The invention relates to hydraulic machines, in particular to hydraulic pulsators, which can be used in various industries for intensification of technological processes, as well as in agriculture, health, and arts and crafts.

There is a method of generating oscillations of a liquid flow, comprising a preliminary separation of the flow on the primary and secondary, twisting the main thread, the partial etching of the additional stream and feeds it to the periphery of the main flow with circumferential velocity less than the main thread, as well as hydrodynamic oscillation generator to implement this method, comprising a housing, a flow chamber therein with a TV twist and a Central body mounted with a clearance relative to the wall of the flow chamber, a pressure line connected to the channel spin, and the output nozzle, an additional line with a flow limiter through which it is connected with a pressure line and through the gap flow chamber with an exit nozzle (RU # 2087756, 20.08.1997 year).

The disadvantages of the known method and device is low and the intensity fluctuations of the fluid flow due to the uncontrolled mixing of the swirling flow with a retarding the flow of the additional line. The red eye reduction is of intensity fluctuations leads and low energy fluid stream in additional highway because of selective grazing pressure, and the presence of a flow limiter that is used to maintain consistent interaction with swirling flow, reduces the working range of flow and pressure. The disadvantages include the need for a preliminary calculation of the additional length of line to maintain oscillations in the flow rate of the fluid in the pressure line.

There is a method of excitation of oscillations of the fluid flow, namely, that the fluid under the same pressure spin and create at least two oppositely directed vortices, the periphery of which is hydraulically connected with the cavity with adjustable elasticity, and an oscillator for carrying out the method, which includes a vortex chamber with a TV twist, at least in two planes of its cross-section with mutually opposite spin orientation and connected to a pressure line, a Central body that is established with a gap in the vortex chamber, the cavity with adjustable elasticity, is in communication with the swirl chamber and through the gap with the output nozzle (RU # 2144440, 20.01.2000 year).

The disadvantages of this method and device are performing channel spin in the vortex chamber and the clearance message cavity with adjustable firmness with the output nozzle at the periphery formed by oppositely directed vortices. This drive is t to premature mixing, inhibition, reduction of the accumulated energy in the cavity with adjustable firmness and size variations in flow through the output nozzle. On the periphery of the formed vortices magnitude of the centrifugal pressure and maximum execution here channels twist leads to the necessity to use high pressure in the pressure line to maintain the intensity of the swirling flow and the magnitude of fluctuations in the flow.

The closest in technical essence and the achieved result when implementation is a method of generating oscillations of a liquid stream, including the tightening of fluid under the same pressure in the two opposite directions in the form of vortices separated by an intermediate nozzle, one of them is connected with the cavity with adjustable firmness, and the other with an output nozzle, and hydrodynamic oscillation generator for its implementation, containing pressure pipeline, a vortex chamber with a TV twist connected with the output nozzle and channels of opposite spin orientation, connected to the cavity with adjustable firmness, intermediate nozzle, separating the spin channels and the channels of the opposite spin orientation and the Central body, installed in the vortex chamber with a gap between its side wall and the intermediate nozzle (RU # 2296894, 10.04.2007,).

p> The disadvantages of the method and its generator can be attributed to the presence of an intermediate tapering nozzle in the vortex chamber in the flow path of fluid moving with the acceleration of the cavity with adjustable firmness through the gap to the outlet nozzle. Additional hydraulic resistance, which creates intermediate nozzle, reduce the effectiveness of the management of swirling flow in front of the outlet nozzle and limits the amount of flow variations through him. The disadvantages include the fact that the spin channels and the channels of the opposite spin orientation is performed in the vortex chamber at the periphery of the formed vortices, and thus creates the maximum amount of back pressure for supplying fluid from the pressure line that leads to further increase in system pressure to maintain operating parameters.

The objective of the invention is to increase efficiency of generation of flow variations due to the optimum conversion of a constant flow of fluid in a pulsating flow and increase the intensity fluctuations due to the reduction of hydraulic losses.

The solution of this problem is achieved by using the known method of generating oscillations of the liquid flow in the environment, consisting in the fact that the fluid of equal pressure pod and tightening the at least two streams in opposite directions and share, one of them is connected with the cavity with adjustable firmness, and the other with an output nozzle, according to the invention, the liquid pre-shared, at least two threads to twist, twirl them at different speeds and at the same time share, swirling flow at a slower speed associated with at least one cavity with adjustable firmness using the channel, and a swirling flow with greater speed - to the output nozzle.

For maximum hydraulic connection this connection it is expedient to carry out through the periphery of the swirling flow at a slower rate as the region having the maximum centrifugal pressure.

Additional regulation of the magnitude of the elasticity of the cavity with regard to its elastic properties and strength of interaction appropriate communication with the swirling flow to make use of the channel inside or outside the cavity with adjustable firmness.

The relationship of the swirling flow with greater speed with the output nozzle provides flow control through it, using this additional cavity with adjustable elasticity extends the control range at the expense of additional accumulated elastic energy.

Frequency-amplitude oscillation parameters are determined by the volume and the value of the adjustable firmness of the cavity, PR is the gas cavity is expedient to regulate the value of its elasticity by pressure, for example, in the pressure line or in the environment.

The problem is solved also by the fact that in the known oscillator liquid flow, comprising a pressure line that is connected to the swirl chamber, the spin channels, the output nozzle, coupled with the spin channels and the cavity with adjustable firmness connected with the channels of the opposite spin orientation, according to the invention the spin channels and the channels of the opposite spin orientation is made in the side wall of the vortex chamber, and the channel spin performed on a smaller radius side wall of the vortex chamber and is connected with an output nozzle, and the channels of the opposite spin orientation is performed on a larger radius side wall of the vortex chamber and is connected through a channel with a closed on the other hand the pipe along its length is set, at least one cavity with adjustable firmness, separated from the pipe and channel sealed with an elastic membrane, and between the spin channels and channels of opposite spin orientation of the installed partition, at least one through-channel.

To regulate the flow of liquid from the channels of the opposite spin orientation in the channel to regulate the force of the compression cavity with adjustable elasticity, it is advisable to establish between them on the additional partition, at least one additional end-to-end channel. The use of end-to-end channel on the radius of the side wall of the vortex chamber is not less than the amount of the larger radius of the side wall of the vortex chamber reduces the speed and impact of flows on each other when tightening. Performing advanced end-to-end channel between the side wall of the vortex chamber and an additional partition promotes optimal conversion constant flow of injection fluid into a pulsating. In both cases, run-through channel and the additional channel monitoring appropriate partition to connect with an additional partition.

To prevent premature mixing and braking oppositely swirling flows through appropriate channel to supply non-return valve.

When the generator of oscillations of the flow is periodic twisting of the liquid before the output nozzle and stop the rotation with the subsequent ejection of fluid into the environment. To reduce the time spent on the twisting of the liquid after it is stopped, it is advisable opposite the outlet nozzle to install additional the swirling chamber, in which a portion of the stream will be on inertia to keep the rotational movement. Additional swirling chamber, the price is EcoObraz set in the partition. When the generator is in the gas environment using additional swirl chamber opposite the outlet nozzle leads to an increase in the amplitude of oscillations of the flow due to the increased volume of the gas cavity formed in the additional vortex chamber on the axis of the twisted, using feeds twist, fluid stream.

For expansion of the amplitude-frequency band oscillations when the generator is advisable to use an additional cavity with adjustable firmness installed in additional the swirling chamber, the adjustable elastic to use inert gas or spring, separated from the liquid through the membrane. For regulating the magnitude of the elasticity of the additional cavity is advisable to fill it with an inert gas under pressure through the valve device, with the aim of preventing destruction of the membrane to set before her the perforated partition.

For regulating the mass of the rotating fluid depending on the flow rate of the pressure line, it is advisable output nozzle is made movable, for example to podporujici relative to the vortex chamber.

The value of the adjustable firmness of the cavity depends on the magnitude of elasticity of the material pressurized elastic shells. To exclude the influence of the panel the guests of material suitable airtight elastic shell to execute inside the channel in the form of a rubber tube, closed with two ends and mounted in a rigid perforated pipe, or in the form of a reinforced rubber tube. To regulate the frequency range of the oscillations, as well as compensation of high pressure in the environment and in the pressure line rubber tube and reinforced rubber tube can be filled with inert gas under pressure through the valve device.

When sharing an adjustable elastic cavity and the elasticity of the material pressurized elastic shells, made in the form of a rubber tube, it is advisable inside it to perform the channel. When this rubber tube, capped at one end and connected the other end of the tube forms between it and the rubber tube cavity with adjustable firmness. The pipe can be filled with inert gas under pressure through the valve device, and when using high values of excess pressure, it is advisable channel be placed in a rigid perforated pipe, which is installed inside the tight elastic membrane in the form of a rubber tube, one end of which is plugged and the other is connected with the pipe. The performance of pressurized elastic shells in the form of a tube allows you to increase the size and strength of interaction of the cavity with adjustable firmness with the liquid in the channel, and reduce glad the social dimensions of the device.

In the invention implements a mechanism of generation of oscillations of fluid flow, which allows to obtain a new technical result, which is that control flow of fluid in the generator is using not less than two separate and oppositely twisted with a different flow rates, one of which is associated with the storage of elastic energy of compression in the form of a cavity with adjustable firmness, and the other with the output nozzle.

Twisting flow in the vortex chamber of the generator is used to create a large hydraulic resistance to fluid flow as temporarily blocking elements due to the greater tangential velocity compared to the radial component. This swirling flow at a slower speed provides by means of the channel the flow of liquid into the cavity with adjustable elasticity, where the energy of the fluid is converted into potential energy of elastic compression. At the same time swirling flow with greater speed blocks the flow of fluid from swirling flow with less speed and movement of fluid through the output nozzle of the generator. Having a larger tangential velocity, swirling flow provides a reliable blocking of the fluid to the outlet nozzle.

Power fluctuations on the eye depends on the size of the accumulated elastic energy in the cavity with adjustable firmness, the mass of fluid in the channel, which operates eject the elastic force, and the hydraulic resistance to the movement of the fluid from the cavity with adjustable firmness through the channel to the outlet nozzle.

The value of the accumulated elastic energy depends on the intensity of rotation opposite to the swirling flow and the maximum in their division. The efficient separation of flow is provided to twisting during tightening, which occurs when the compression cavity with adjustable elasticity due to the action of pressure fluid mass through the channel from the swirling flow with a lesser rate.

When the ejection of the fluid mass under the action of forces adjustable elastic cavity back through the channel provides effective braking swirling flows and removing their blocking action on the liquid, moving to the outlet nozzle. Braking performance depends on the mass of fluid moving with acceleration through the channel towards the output nozzle. While on the path of the fluid minimum resistance is provided by a more straightforward, unlike the prototype, the movement with adjustable pass-section.

The design of the oscillator liquid flow conversion efficiency of forward fluid flow in a pulsating provided by done is of the spin channels and channels of opposite spin orientation at different radii of the side wall of the vortex chamber, unlike the prototype, in which the twisting of threads going on the same radii, where the centrifugal pressure maximum, mean, and maximum resistance to movement of fluid from the pressure line. Energetically favorable fluid flow in the channels twist in the region of the swirling flow, where the pressure is lower than at the periphery, i.e., a smaller radius of the housing of the vortex chamber. According to the law of the constancy of circulation, used in theory of centrifugal vortex nozzles [Abramovich, N. Applied gas dynamics. M., 1953. S. 63], the twisting of the liquid through channels twist on a smaller radius allows you to achieve greater tangential velocity before the output nozzle is more effective to block the exit of fluids from it and increase the value of the accumulated elastic energy. Fluid flow through the channels twist on a smaller radius can significantly reduce energy losses, to increase the power of the swirling flow and the magnitude of fluctuations in the flow.

For efficient separation of oppositely twisted threads to prevent from premature inhibition between channels twist and channels of opposite spin orientation is installed partition with a through channel, for example, in the form of cylindrical holes. These holes are not passed into the effects of each other torques in rotating flows, but ensure the effective transfer of the centrifugal forces that hold the cultivation liquid mass, compressing the cavity with adjustable firmness. For the temporary accumulation of fluid channels of opposite spin orientation, performed on a larger radius side wall of the vortex chamber, connected through the channel closed on the other side of the pipe along its length is set, at least one cavity with adjustable firmness, separated from the pipe and channel sealed with an elastic membrane. Pipe, closed at one end, protects the cavity with adjustable firmness from the action of the pressure in the pressure line, and the tight elastic envelope - from action of fluid pressure in the channel. The performance of the cavity with adjustable firmness along the channel allows you to adjust the amount of fluid mass, compressing the cavity, depending on the intensity of rotation of the flow in the vortex chamber. When the generator is the mass of the fluid interacts with the cavity with adjustable firmness through a tight elastic membrane and makes the channel reciprocating motion. Execution cavity with adjustable firmness along the channel in the tubular embodiment, due to the maximum area of interaction allows to achieve high values of elastic energies acting on the LM is a bone in the channel when using the minimum radial dimensions of the device. Regulation of the magnitude of the forces of elasticity can be produced by setting the pipe two or more cavities with different values of the adjustable elasticities, which allows to expand the range of emitted frequencies and to increase the reliability of the device as a whole.

These advantages, and features of the present invention are illustrated by the choice of its performance with reference to the accompanying drawings.

In Fig.1 shows the diagram of the oscillator liquid flow when performing its basic formula,

in Fig.2 - section a-a and b-b In Fig.1,

in Fig.4 - option of its performance with additions on PP.10, 13.

Since the claimed method is implemented during operation of the proposed oscillator, the method described in the description section of the description of the operation of the device.

An oscillator liquid flow contains a vortex chamber (1) with spin channels (2) and channels of opposite spin orientation (3), performed at different radii in the side wall of the vortex chamber (1). Inside the vortex chamber (1) between the channels of spin (2) and channels of opposite spin orientation (3) there is a partition (4) with a through channel (5). Front wall (4) by channel spin (2) set the output nozzle (6).

On the other side of the s wall (4), side channels of opposite spin orientation (3), swirl chamber (1) connected to pipe (7), closed with the other hand. In the pipe (7) have a cavity with adjustable elasticity (8) forming a channel (9). Cavity with adjustable elasticity (8) is separated from the pipe (7) and the channel (9) is sealed with an elastic sheath (10). For supplying fluid under pressure into the channels of spin (2) and channels of opposite spin orientation (3) use a pressure line (11). Between the pipe (7) and swirl chamber (1) can accommodate an extra partition (12), at least one through channel (13), and in the septum (4) can be made more swirl chamber (14).

An oscillator liquid flow works as follows. Previously, depending on the operating range of the flow rate and pressure in the pressure line (11)and the pressure in the environment, make a calculation of the geometric parameters of the generator and the magnitude of the adjustable firmness of the cavity (8).

An oscillator liquid flow is fixed in the pressure line (11), for example, using the vortex chamber (1). Then the fluid from the pressure line (11) is served in the channel spin (2) and channels of opposite spin orientation (3)made in the side wall of the vortex chamber (1). Swirling through the channels of spin (2) the flow due to the large tangential velocity component of blocking the flow of fluid through outlet nozzle (6). At the same time using centrifugal pressure of this flow is blocked to fluid flow through channel (5) from the side opposite to the swirling through channels of opposite spin orientation (3) stream. Blocking oppositely swirling flow occurs without inhibition, as through channel (5) does not transmit the torque action of the force from the swirling, using feeds twist (2), stream.

Swirling through the channels of the opposite spin orientation (3), the fluid flow passes through the channel (9) in closed on the other side of the pipe (7) and compresses located along the channel (9) cavity with adjustable elasticity (8), closed airtight elastic shell (10). The pressure in the cavity with adjustable elasticity (8) increases due to the inertia of the fluid mass in the channel (9) to a value exceeding the value of the centrifugal pressure through the channel (5). Upon reaching a critical value of the compression ratio and the elastic force is a braking first twisted channels of opposite spin orientation (3) flow, reducing the centrifugal pressure through the channel (5), and then the braking twisted channels of spin (2) flow. As a result, the accession of a moving fluid mass from the channel (9) to the swirling flow causes them to stop and abrupt ejection of fluid is STI via the outlet nozzle (6) into the environment. After the liberation of the pipe (7) from excess fluid mass and reduce pressure in the cavity with adjustable elasticity (8) processes the swirling flow in the vortex chamber (1) resume. To increase the pressure of the compression cavity with adjustable elasticity (8) can accommodate an extra partition (12), at least one through channel (13). Thus the value of pressure is also governed by the centrifugal pressure on the additional pass-through channel (13), which is performed on the corresponding radius of the vortex chamber (1). Before the outlet nozzle (6) in the partition (4) establish additional vortex chamber (14), which allows to reduce the time and increase the intensity of the swirling flow.

FIELD: chemical and petroleum refining industry; production of devices for a dispersion, homogenization and mixing of streams of liquids.

SUBSTANCE: the invention is dealt with devices for a dispersion, homogenizations and mixings of streams of liquids and may be used for intensification of technological processes in petroleum refining industry, chemical and other industries and also for homogenized treatment of heavy petroleum kinds of fuel used in industries and heat power engineering. The hydrodynamic corrector of streams of liquids contains a body 1 with an inlet branch-pipe 2 and an outlet branch-pipe 3. Inside the body 1 there are: a distributor 4 made in the form of a disk with holes 5 and installed with a capability to overlap a working chamber of the body 1 and a tool to provide a speed-up of the treated stream made in the form of a disk 7 with a through conical hole. The distributor 4 has a dome 8. Inside the hydrodynamic corrector in the zone of the outlet branch-pipe 3 there are an emitter 9 with crescent blades 10 and a disk 11 with a through hole installed in the zone of the outlet branch-pipe with a capability to form a cylindrical chamber 12. The distributor 4 with the dome 8 and the disk are located from each other with a capability of formation of a ring channel 13. The emitter 9 dressed on 11 disk 7 are located in respect to each other with a capability to form a ring-shaped channel 13. The emitter 9 is fixed on the disk 11 with a capability to form a zone of mixings 20. Through the inlet branch-pipe 2 the treated stream of a liquid is directed inside the body 1 and through holes 5 of the distributor 4 is directed into the ring-shaped channel 13. Due to contraction of the passing cross-section of the ring-shaped channel the speed of the stream increases and the pressure drops. At the channel outlet the stream runs onto a deflector 14. At the expense of it in the ring-shaped groove 16 a toroidal vortex cavitation zone is formed. Then the stream is rejected into the chamber 6. Then moving in the chamber 6 the stream falls in a conical hole of a booster. Because of a contraction of the passing cross-sections the speed of the stream increases and pressure drops. The stream of liquid coming out of the hole of disk runs onto the deflecting surface 18 of the emitter 9 made in the form of a spherical pit and being deflected from it forms a toroidal vortex cavitation zone again. After that the stream is thrown out into the chamber 19 and moving through it falls through blade-shape vanes into a zone of mixing 20 and then at an acute angle - onto walls of vanes 10, due to that transformation of the treated stream energy into the energy of acoustical oscillations of a broad spectrum is ensured. Under action of the acoustic oscillations in the stream a zone of an acoustic cavitation is formed. In this connection the stream from a cylindrical hole of the disk falls into the chamber. In the chamber the braking of the stream takes place and due to that the final treatment of the stream is ensured, that is appearance of the cavitation bubbles into the outlet branch-pipe 3 is prevented. The technical result is an increase of a degree of dispersion and homogenization of a treated stream.

EFFECT: the invention ensures an increased degree of a dispersion and homogenization of a treated stream.
