The invention relates to a power system and can be used in heating systems and heating apparatus of wide application.
Known heat source described in the patent of Russian Federation №2045715, CL F 25 29/00, publ.10.10.95. According to this invention, in the heat, having a cylindrical body with h the s to the cylindrical body portion. In the base of the cylindrical portion opposite the cyclone mounted brake device.
The working fluid is supplied under pressure through a nozzle placed tangentially to the cyclone body. Inside the heat source occurs strongly swirling motion of the fluid. However, in accordance with the laws of thermodynamics, fluid mechanical energy is converted into thermal energy.
The disadvantage of this generator is to reduce the intensity of heating of the fluid due to the decreasing velocity of the fluid as it is removed from the cyclone, and hydrodynamic losses due to the small diameter and large length of the overflow pipe. All this reduces the effectiveness tepdogeneratora in General.
The closest analogue of the invention is a vortex heater (patent RF № 2129689, CL F 25 29/00, 27.04.99). Vortex heater includes an inner cylindrical shell, one end of which is set accelerator of the fluid made in the form of a cyclone, the inlet of which prednaznachen to connect to the pump. Additional outer shell located around the inside. Between the shells is a spiral channel. In the inner shell at its end, Realny channel between the shells. The outlet is located on an additional (outer) shell side of the accelerator of the fluid.
A disadvantage of the known device is the presence of spiral channels, which do not allow to develop liquid highest possible speed in the case of the heat source, because the fluid is forced to move along a spiral channels, which create at the beginning of the flow of the braking effect. Because of this, when the braking fluid at a lower speed generates less heat.
The technical problem of the invention is to increase the efficiency of the heat generator by creating the maximum velocity of the fluid inside the heat source, effective braking and exhaust heated liquid.
The problem is solved so that the heat-generator-containing accelerator of the fluid in the form of a cyclone with an inlet pipe for supplying fluid under pressure hull of the two tubular shells - inner and outer, of the outlet pipe connected to the outer casing, according to the invention, the inner and outer casings are placed symmetrically on both sides of the cyclone and in the far end from the cyclone muted, and the inner shell on the remote from the cyclone area per two shells symmetrically on both sides of the cyclone allows you to create maximum initial velocity in the cyclone, because the annular jet diverge on both sides, without creating interference to the flow and the initial part of the inner shell of the heat source without providing additional resistance.
The perforated portion of the inner shell is an effective braking device for the rotational motion of the fluid at high speed.
Plugged the ends of the inner and outer shells of the body heat source cause spun up to high speed fluid flows completely through the perforated portion of the inner sheath in the annulus, when this happens the brake fluid without hydraulic shocks, and the kinetic energy of the fluid is transferred into thermal energy.
The connection housing outer shells common outlet pipe ensures the effective use of both halves of the body heat source placed on both sides of the cyclone.
Boiler scheme is shown in the figure.
The heat source comprises an accelerator of the fluid 1, made in the form of a cyclone, the body consisting of the outer shell 2 and the inner shell 3, the perforated portion 4 of the inner shell, the cover 5 of the housing, a nozzle inlet 6 with the nozzle, atronomy the pipe 7 is then connected circuit of heat and fluid return line on the pump intake (not shown).
The generator works as follows.
The working fluid by the pump under pressure supplied through pipe 6 into the cyclone 1. At the entrance to the cyclone 1 pipe ends with the nozzle placed tangentially to the wall of the housing of the cyclone and section 5-10 times smaller than the cross section of the pipe 6. Of course, from the nozzle the liquid flows at high speed and moving in strongly swirling condition on the cylindrical wall of the cyclone and the inner shell boiler through the ring-shaped path.
However, due to internal friction in the fluid layer and wall friction the kinetic energy of the flow is turning into heat. On a perforated portion 4 of the inner shell 3 of the body heat source due to inertial forces holding the liquid to the wall, the annular movement of the liquid through the radial channels perforation flows into the annulus between the inner and outer membranes of the body heat source. This dramatically slowed the annular fluid movement, of the stream of liquid coming through the canal perforation hit the wall of the outer shell 2.
Thus, the perforated portion of the inner shell kinetic energy of the fluid flow rapidly pre is OK 7. Heat the liquid in the initial period and maintaining the required temperature is effected by the circulation of the liquids in a small loop from the output pipe 7 directly to the pump intake and feed back to the input pipe 6. The heated liquid to the required temperature goes on a path of heat consumption. If necessary and rational use of body heat boiler and insulated pipelines.
The heat source can be operated without a personal pump. One pump is sufficient performance can provide multiple heat generators placed at several sites of the heat consumer. In addition, a heat source can be operated through the selection of the flow of fluid, such as pressurized water, oil and so on
The symmetrical arrangement of body heat from the inner and outer shells on both sides of the cyclone reduces initial resistance at the entrance of the liquid in the heat generator allows you to create the maximum speed of the swirling annular liquid flow that ensures the maximum amount of heat in the heat.
Perforation only the final part of the length is in the swirl and braking just flow without hydraulic hammer and the gradual removal of the heated first layer flow at the wall.
Silencing the far end of the inner and outer shells makes the entire flow through the perforated portion with a maximum heat. In addition, the friction of the muffled face allocated an additional amount of heat.
Common outlet for the hot liquid from the two halves of the body heat source provides a self-flux distribution inside the heat source.
Thus, the solution of the technical problem - improving the efficiency of the heat generator by creating maximum velocity of the fluid inside the heat source and effective braking and selection of heated liquid.
