VORTEX HEAT-GENERATOR

This invention belongs to heat-and-power engineering and, in particular, is intended for heating of various premises and hot water supply. This invention can be also applied in various industries, in particular for processing of liquid mediums, thus obtaining necessary physical and chemical technological properties.

Well-known mechanical heat-generator [1], which heat exchanger is simultaneously works as a water circulation balancer and water generator consists of discs, and the inlet branch pipe is equipped with internal Archimedes's screw allows avoiding application of the circulation pump. One of the disadvantages of the present invention is rather complex construction of the hot water generator and significant rotational frequency up to 1000 rpm.

Another known type of rotary pump heat-generator [2] is characterized- with the following: rotation of the rotor shaft inflows fluid into the axial chamber, where it passes on the vanes of rotating rotor, made in the form of bilateral impeller of the centrifugal pump. Then fluid passes through the aperture of rotor ring and stator. It provides conditions of cavitation, which ensure intensive heating of fluids. One of the disadvantages of the present invention is rather complex construction of the rotor and stator and even the presence of the stator. Considering this, effective heating of fluid requires high frequency rotation of the rotor, which in turn reduces service reliability of the heat- generator.

Cavitation-vortex heat-generator [3] represents itself most similar technical invention to the present device in technical essence and achievable results. The cavitation-vortex heat- generator has a body with feed and discharge branch-pipes, a stator is installed in the body, it has two annular disks perforated by through holes, and two rotors installed between the disks of the stator with a gap relative to each other and the disks of the stator installed on independent shafts having independent drives and rotating in the opposite directions. One of the main advantages of the present invention is the application of two rotors with independent drives that 'allows intensifying heating of liquids, but at the same time, presence of stator not only complicates heat generator's design, but also requires high frequency rotation of ^~ the rotor, which in turn reduces service reliability of the heat generator.

Technical result of the present invention is the increase of the liquid heating efficiency due to intensification of the heating process.

The mentioned technical result is achieved, because the vortex heat-generator has a body with inlet and outlet branch-pipes and rotors installed in the generator's body in the from of two

coaxial disks positioned with a gap relative to each other on the independent shafts, having independent drives rotating towards each other, is distinguished, as the internal plane of the discs is equipped with the rings, having openings positioned on the whole diameter with possibility for engagement of the rings of one disc between the rings of the other disc, radially directed blades and shafts are equipped with iron rings, helical ports are positioned on the shafts along the full length of the contact with iron rings and the inlet branch-pipes are positioned on the iron rings in front of helical ports of shafts.

The specified purpose can be achieved by the following. The Section of the prospective vortex heat-generator is shown on the draft below. Vortex heat-generator has a body (1), inlet (2), and outlet (3) branch-pipes, rotors installed inside the body of the heat pump, made in the from of coaxial disks (4) and (5), installed with the gap relative to each other on the on independent shafts (6) and (7), having independent drives and rotating toward each other. The internal plane of the discs is equipped with the rings (8) and (9), with openings (10) positioned on the whole diameter with possibility for engagement of the rings of one disc between the rings of the other disc. Radially directed blades (11) and (12) and shafts are equipped with iron rings (13) and (14). Helical ports (15) and (16) are positioned on the shafts along the full length of the contact with iron rings. Inlet branch- pipes (2), are positioned on the iron rings (13) and 14 in front of helical ports (15) and (16) of shafts (6) and (7). The prospective vortex heat-generator works as follows:

The cold fluid, for example water, passes into the chamber A through the inlet branch- pipes (2), at the rotation of shafts (6) and (7) and due to depression origin,ating at the helical ports (15) and (16) and hard contact with inner surface of the inner rings (13) and (14). Then the fluid passes through the helical ports, where rotational fluid motion ensures intensive heating and additional heating due to friction of the contacting surfaces of the shaft and iron rings into the chamber B. Then the warmed-up whirling water hits on the outer side of the discs (4) and (5) and undergoes braking, as rotation of discs is opposite to the rotational motion of the fluid and efficiency of the fluid braking increases due to radial blades (11) and (12). It results in excessive pressure and origination of fluctuation, which in turn results in even more intensive heating and origination of vapor-pressure pockets, which collapse's efficiency increases as a result of acoustic effect, which originates at counterrotation of discs (4 ) and (5) due to installed rings (8) and (9) with openings (10). Then intensively heated fluid hits on the peripheral face of the body (1) and can be delivered to the hot water supply or heating systems through the outlet branch- pipe (3).

Installation of rings on the inner plane of the discs, with openings positioned on the whole diameter with possibility for engagement- of the rings of one disc between the rings of the other disc allows creating acoustic effect. Thus, generation of acoustic vibrations occurs due to counterrotation of rings with openings, increases efficiency of vapor-pressure pockets collapse and provides intensive heating of water.

Radially directed blades installed on the outer surface of the dicks form effective rotating detacher of vortex flow, thus providing instant heating of water due to effective vortex flow braking, pressurization and initiation of pulsations. At the same time, rotation of discs ¹ in the direction opposite to the rotation of vortex flow aliows increasing the speed of the vortex flow braking, and provides intensive heating of water.

Equipment of shafts with the iron rings and arrangement of helical ports along the full length of the contact with iron rings, allows providing heating fluid with vortex motion, thus ensuring additional heating, originating as a result of friction between contacting surfaces of the shaft and iron rings. Helical ports generate depression and ensure rather intensive heating of the fluid, simultaneously with the supply of fluid, and do not require application of special pump, intended for the supply of fluid.

Location of inlet branch-pipes on the iron rings in front of helical ports of the shafts ensures supply of the initial fluids without application of pumps.

Application of the prospective vortex heat-generator allows considerable increase of the energy production efficiency due to vortex motion with subsequent effective braking of the vortex flow, originating due to counterrotation of the- rotating detacher with the vortex flow with simultaneous acoustic effect.
