The invention relates to an apparatus and method for input and distribution of a fluid medium, in particular gas-containing liquid in a container according to the preamble of claim 1 of the claims. The capacity can be implemented as a device or as a separation device. The invention also relates to a container having such a device.

The mere possibility of entry of the fluid into the container is an inlet attached to the vessel wall. Fluid is a gas containing liquid is distributed therein in the form of small droplets. The distribution of the fluid in the vessel cannot be affected downstream from the inlet. Fluid is not distributed evenly in the inner space of the tank. Intake device for a fluid medium with improved distribution of the fluid is known, for example, from the publication WO 06122940. The device includes a vertical channel adjacent to the intake pipe and passing essentially over the entire diameter of the vessel. This distribution channel has a plurality of deflecting plates. Each of the guide plates is centered around one part of the flow of the first fluid and rejects the first fluid medium is essentially 90°. Fluid, in this case, is introduced into the container on the left and on the right side of the tank. Simultaneously the separation of the Jew�spine from a fluid medium, far from deflecting plates in the form of a gas with a portion of the residual liquid.

The gas passes through the tank and comes to contact the surface on which the gas and residual liquid are separated due to different density. The liquid is separated at the contact surface, and the gas passes through the contact surface. The contact surface may, for example, be formed as a woven separation device.

The device according to the publication WO 06122940 represents an improvement over the inlet, since gas is more evenly distributed in the tank. However, it was discovered that the separation of the liquid occurs in an unsatisfactory manner, and the liquid is drawn in part of the capacity is located downstream from the contact surface.

Moreover, it is found that the cross-sectional area of the tank, located downstream from the device according to WO 06122940, has two relevant areas in which the gas flow rate is greater than in the rest of the surface cross section.

This means that the device according to WO 06122940 should be recognized as representing an improvement of conventional inlet pipe into the vessel wall, but it turns out to be unsatisfactory due to the uneven distribution of gas in the tank, the so-called broken Cam�tion remains, and liquid is drawn in part of the capacity is located downstream from the device.

Therefore, the object of the invention is to provide a device for the distribution of fluid medium in the vessel, whereby is obtained an improved separation of the fluid on the gas and the liquid and a uniform distribution of gas in the tank.

This is the challenge that the device for introducing and distributing a fluid into the inner space of the tank. The device includes an inlet channel and distribution channel. The inlet channel is open into the distribution channel with the possibility of directing fluid from the inlet channel into the distribution channel. The distribution channel has a shell having at least one outlet. The inlet channel is connected with a distribution channel with at least one opening disposed in the shell of a distribution channel. The hole is located so that fluid enters the distribution channel is tangential to the hole with the possibility of creating a rotating flow in the inner space of the distribution channel. The distribution channel is preferably designed in the form of a tubular element having, in particular, axisymmetric cross-section, preferably a circular cross-section. Hole location�but in the shell, in particular tubular sheath distribution channel, made in the form of a tube element, thus, the fluid passes through the hole tangentially relative to the pipe shell.

Fluid is a compressible fluid, typically a gas containing liquid, distributed in Gaza in the form of drops. The gas coming from the inlet channel, thus is routed through a hole in at least one distribution channel, preferably in a variety of distribution channels. The distribution channel is at an angle greater than 0° and less than 180° to the inlet channel, in particular an angle greater than 60° and less than 120° to the inlet channel. According to the private preferred embodiment of the angle between the inlet channel and the discharge channel is approximately 90°.

Important is different from the prior art, the location of the hole in the distribution channel. The opening may, in particular, to be located in the upper half or lower half of the shell. The flow to the distribution channel, thus, goes on a tangent. The advantage is that portion of the stream can be branched off at the next junction canal, on the one hand, and fluid enters through the opening into the distribution channel at a tangent, on the other hand�. In this case, the “tangent” means that fluid passes through the hole essentially parallel to the tangent at the point of distribution channel, nearest to the top or bottom of the inlet channel. If fluid is in the distribution channel, the fluid deflected by the inner wall of the distribution channel. Fluid when it is driven in rotation, and the liquid droplets in the gas are accelerated in the direction towards the pipe wall and are then separated on the inner surface of the shell and is displayed through the item collection of fluid. The efficiency of separation of liquid from gas, while increasing through more intensive contact with the inner wall of the distribution channel. The liquid thus separated and displayed in front of the inlet into the container and, thus, does not reach the main stream of gas. According to a preferred variant implementation, the plurality of holes are located in particular in the upper half of the shell; according to the private preferred embodiment of the two holes located in the upper half of the shell.

The hole may, additionally, have the guide piece. The guide element, in particular, made in the form of a reed made by punching in the wall of the distribution channel and then bent. Alternative �whether in addition to this, can also be created a lot of guide elements. The guide element can be either in the internal volume of the distribution channel, but can also act out of a distribution channel in the direction of the inlet fluid. The guide element may, in particular, to act in the direction of the internal space of the distribution channel and to be on the edge of the hole, which is achieved by the first flow of fluid, and can be oriented upstream at the hole edge, which the flow of fluid reaches the last. Thus to give the fluid more accurately defined flow direction can be performed in the air supply conduit, so that less edge vortex flows are generated in a rotating flow, which can have harmful effects on the separation of liquids. Guide elements can also be welded separately to the tubular element forming the distribution channel.

Preferably, there is an element of the fluid collection, which may be the inlet channel or the channel element, placed on the wall of the distribution channel or distribution element, and coupled with the outlet of the liquid in the wall of the distribution channel or distribution of the item. The liquid separated on the inner surface� the casing wall, can be put outside the sheath of the distribution element or a distribution channel through the element in the direction of the fluid. Element of the collection fluid may comprise at least one hole for drainage.

In the area of the element of fluid collection or upstream from the element collection of fluid may be located in the pre-separation element. The separation of the liquid can be further improved by pre-separation element. If the pre-separation element is designed in the form of a structure containing voids, such as a filter, a woven material, woven material or felt, the droplets may be trapped in the structure, can connect and be directed to the outlet opening of the fluid. Alternatively, the pre-separation element may be configured as a locking element, which fluid hits and undergoes a forced deviation. The locking element may also have a throttle action. The locking element may additionally be arranged so that the separated liquid is routed directly to the outlet of the liquid. The shorter the length of the hole at a constant width of the hole, the more significant is the revolving flow path length from the hole to the exhaust hole�of rste increases for shorter holes and the number of cycles of rotation increases until reaching the fluid outlet. Hole can, in particular, perform in the form of a slit, and the distance between the first end of the slit and the second end of the slit hole is a long hole. The distance between the first wall and the second wall of the hole is the width of the hole. First wall and the second wall, in this case, pass between the first and second end of the slit.

According to a preferred embodiment of the distribution channel can join the distribution element, wherein the distribution channel and the distribution element is connected to the outlet so that fluid may be directed from the distribution channel in the junction element.

The distribution element has a shell with a slot made in it, through which the fluid may be directed into the inner space of the tank. The slot is located on the control element so that the gas flow essentially in the direction of the longitudinal axis of the tank. This means that the gas separated from the liquid that emerges from the slits, which can, in particular, to perform in the form of slotted holes in the direction of the longitudinal axis of the container. In particular, the distribution element may have a tubular configuration element.

Shell junction element has a first end of the shell and the second end of the shell, so about�points passes between the first and second ends of the shell. The shell can be directed through the inlet channel so that the shell forms a distribution channel in the inlet element. Alternative to this, the distribution element may be sent through a distribution channel that may contain a cutout from the interior of the distribution channel. Alternative to this, the first end of the casing, the distribution element may be adjacent to the distribution channel or to speak in the distribution channel.

The slot can be performed in the form of a slit having a longitudinal dimension extending from the first to the second end of the slit. First wall and second wall extend between the first and second ends of the slit. The average distance between the first wall and the second wall of the slit is the slit width. The longitudinal size of at least twice, preferably three times, particularly preferably at least five times the width of the slit to achieve as far as possible a uniform distribution of gas across the cross sectional area of the vessel.

The width of the openings in the distribution channel is preferably greater than the width of the slit, in particular, when the longitudinal size of the slot is greater than the width of the hole or if a lot of the slits is made near one another.

Preferably the distribution element has an element of fluid collection for a direction�Oia fluid, separated at the inner wall of the shell from the outer shell surface of the distribution element.

Preferably in the inlet channel has many distribution channels.

The device is preferably used according to one of the aforementioned embodiments of the separating device or in the mass-transfer device.
