The housing 1 and the rotor 5 of the heat generator made of normal steel and coated by spraying with zirconium oxide.

Consider the multifunction vortex heat generator according to the first variant (Fig 1). The generator works as follows. After filling the heating system and the closed casing 1 heat source through the inlet pipe 2 of the working fluid (water) is included with the motor 11 drives 10, driving the turbine 7 together with the disks 6 and the fluid. After passing through the turbine 7 with two sides and a conically cylindrical holes 12 drive 6, the fluid flows are divided into many powerful jets on each disk 6 and are directed towards each other, and then after the collision of these flows are discarded due to the centrifugal force in the perpendicular direction between the rotating in opposite directions disk 6 with the fingers 13. Sanitization between the rows of fingers 13 of the disk 6, the liquid due to centrifugal force thrown onto the wall of the housing 1, and then flows through the pipe 3 into the fluid collector 4, included in the heating duct, through the circulation pump 14.

In the cavity between the discs 6 with the fingers 13 are formed a powerful vortex flow of liquid from the center to the periphery of the disk 6, which increases the cavitation process. In the result, the vortex is formed inside the region of exhaustion, in which p is oshodi the occurrence of cavitation bubbles, in areas of high pressure in counter flow micro-bubbles “burst” on the walls of the disks 6 and the inside of the fluid flow with the rapid release of energy in thermal infrared range without destroying the disks 6 with the fingers 13. Temperature control of the heated fluid in the collector 4 is on-off motor 11 according to the signals of the temperature sensor installed in the collector 4 heated liquid. When the coolant maximum temperature specified by the consumer (not >95°C), the motor 11 is turned off, when the cooling fluid (water) to the minimum set temperature (<65°C) motors 11 are included. Upon reaching the upper or lower level in the collector 4, the signal from the level sensor is supplied to the operator trunk. During the heating season average heat works 25-30% of the time.

Compared with the prototype of the proposed design multifunction vortex heat generator provides a more rapid heating of the liquid, easy to manufacture, reliable in operation and can be used for grinding, mixing, activation, degradation of liquid and granular components.

Consider the multifunction vortex heat generator according to the second variant (Figure 2).

Heat work is t similarly, as the heat generator according to the first embodiment (Fig 1), but with the following fundamental difference. The principal difference is that the fingers 13 (2) disks 6 of the rotor 5 made in the form of an ellipsoid of finger-blades, perforated through conically cylindrical holes 15 and secured to the disk 6 so that the holes 15 of finger-blades 13 are orientated in the direction of rotation of the discs 6 and when the rotation of the disk 6 create heavy duty zones of compression and rarefaction within the fluid flow, which dramatically reduces the time required for heating the liquid, and a device 16 for regulating the rotational speed of the motor 11 by means of the frequency Converter allows you to create optimum heating the liquid.

Consider the multifunction vortex heat generator according to a third variant (Figure 3).

Heat works the same way as the heat source in the first embodiment (Fig 1), but with the following difference. The difference lies in the fact that the heat source is supplied by a control unit 17 (Fig 3), which is used to soft start the motor 11. Before putting the boiler into operation at the control unit 17 are upper (>95°C) and lower (<65°C) temperature limits fluid. When the temperature of the liquid in the collector 4 of the upper limit of the electric motors 11 otkluchayut is, and when reaching the lower limit is smoothly incorporated. Coating the inner surface of the housing 1 and the working elements of the rotor 5, the shafts 8, turbines 7, disk 6, the fingers 11 wear-resistant ceramics (zirconium oxide) significantly increases the time efficiency of the heat generator.

Compared with the prototype of the proposed options for multi vortex heat generator provide faster heating the liquid, the simplification of the structure (in the prototype of the present complex system of pipes, reducer in the form of a belt and a small maintainability) with a simultaneous increase reliability and extend the scope of application in other industries.

SUBSTANCE: steam from electric steam generator is delivered to jet apparatus nozzle where it is mixed with cold liquid flow for forming two-phase flow at acceleration to supersonic velocity. At mixing chamber outlet, this two-phase flow is decelerated for forming shock wave and converting the flow into liquid flow after shock wave. Then, flow is divided and one part is directed to heat exchanger of vortex tube where it is heated and directed for replenishment of electric steam generator. Other part is directed to nozzle apparatus where it is accelerated to supersonic velocity for forming two-phase flow, after which it is decelerated for converting it into liquid flow saturated with micro-bubble component. Nozzle apparatus outlet is connected with swirler inlet where vortex flow is formed; from swirler, flow is directed to vortex tube where heat is released and flow is divided into hot and cold components. From vortex tube, flow is directed to heat exchanger for transfer of heat to second loop; cooled liquid flow is directed to ejector inlet.

EFFECT: enhanced efficiency of plant.
