After estimating the number of work cycles, capacity and efficiency of the hydro-cavitation heat of the heater can be made comparative characterized the tick of produced and consumed energy on heating the mixture of water and air on the following physical values.

Determine what amount of heat required to heat 100 kg of water at 40°From 20 to 60°C.

if you take 1 kg of pure water and heat it on 1°it will require a certain amount of heat. This amount of heat is taken as the unit of heat is called the large calorie or kilogram-calorie ( kcal)

therefore, to heat 1 kg of water by 1°you will need 1 kcal

- obviously, for heating 100 kg of water at 40°need

40×100=4000 kcal of heat,

where:

1 W·h = 3600 j

1 kW·h = 100 W·h

1 kW·h = 3600000 j = 860 kcal

1 kcal = 4190 j = 1000 cal = 0,0011627 kW·h

Determine how many kW·h will be required to heat 100 kg of water at 40°

1 kW·h = 860 kcal

X kW·h = 4000 kcal

or

1 kcal = 0,0011627 kW·h

4000 kcal = X kW·h

or

1 kcal = 4190 j

4000 kcal = X j

where:

1 kW·h = 3600000 j

X kW·h = 16760000 J.

It should be stressed (see formula Belashova 8)that by increasing the temperature of the mixture of water and air in the hydro-cavitation heat the heater, reducing the density of water and its kinematic viscosity is changed and the efficiency of the asynchronous motion of the of the motor. Change the power factor when the load changes on the motor shaft is as follows. At idle cosϕ the engine is small (about 0.2), as the active component of the stator current due to power losses in the machine, is small compared to the reactive component of the current that generates the magnetic flux. When you increase the load on the shaft cosϕ engine increases, reaching the highest values (0,8-0,9) by increasing the active component of the stator current. At very high loads there is some decrease in cosϕbecause due to the significant increase of the slip and the frequency of the current in the rotor increases reactance winding of the rotor. Curve efficiency η has the same appearance as in any machine or transformer. At idle efficiency is equal to zero. With increasing load on the shaft of the engine efficiency increases sharply and then decreases. The highest value of efficiency reaches with such a load, when the power losses in the steel and mechanical losses, independent of the load equal to the power losses in the windings of the stator and rotor, regardless of the load.

Depending on the ratio of hydro-cavitation cavitation thermal heater figure 7 shows the graph of the maximum force of the jet stream 131, the effective force of the jet of water flow a minimum strength of the jet stream 133, where stream water stream passes through the pipeline and a narrowing device hydro-cavitation heat of the heater per unit time t. The graph shows the force, which is itself cavitation taking into account the power loss by friction of a mixture of water and air in the pipeline and the power losses eddy resistance of a mixture of water and air in the boundary layer orifice hydro-cavitation thermal heater. In this case, the boundary layer that separates laminar and turbulent flow of the mixture of water and air in the hydro-cavitation thermal heater is refractory insert 17 and refractory insert 47. From the geometric shape of the refractory inserts depends on the resistance of a mixture of water and air in the boundary layer orifice and the intensity of the vortex loop. Cavitator 9 or 40 made of blades 134, Fig. To increase the degree of cavitation and improve the quality of mixing finely blends the blades of the cavitator 9 can be composed of an even or odd number of sections 135, 136 and 137. For example, section 135 of the cavitator 9 must be shifted relative to sections 136 and section 136 should be shifted relative to section 137. The blades of each section can have holes of different diameter 138 and the perforation channels 139, and in some cases the La grinding coarse chemical components cavitator 9 or 40 may be made in the form of a screw. The device separating seal 26 is made in the form of a chamber filled with a separating fluid (e.g., lubricating oil), and provides lubrication for the cylindrical heat-resistant end seals 24 and a cylindrical end floating podrejenih seals 25, maintaining a predetermined pressure by means of capillary tubes 27 and devices pressure control 28. Device pressure regulating 28 contains the regeneration mechanism of the separation of the liquid and the mechanism for disposal of harmful compounds.

Works hydro-cavitation heater heat for Autonomous heating systems, low and medium power as follows.

Turns on the electric actuator 10, which through heat device 96, the shaft 8 transmits rotational moment to the cavitator 9. Included electric actuator 97, through which the heat-shielding device 98, the shaft 71 transmits rotational moment to the cavitator 40. From the tank 94 through pipelines laminar flow of a mixture of water and air is fed into the chamber 85 through the input device of the working mixture 5 and the chamber 87 through the input device of the working mixture 86. Further, under the pressure of a mixture of water and air flows narrowing device 7 through the cavitator 9 and a narrowing device 41 through the cavitator 40. Passing a narrowing device 7 and 41, laminar fluid flow in cuause the device is accelerated, which leads to the pressure drop of a mixture of water and air and increase air bubbles (cavities). When you exit orifice mixture of water and air becomes turbulent fluid flow, in which there is a gap of air bubbles (cavities) and the intensive impact of heat energy through conduction and convection, which has accumulated in the air bubbles (cavities). Thermal energy, which was formed in the intermediate chamber 89, will be transferred to the transfer device and the heat 91, which is made in the form of a boiler, having the inlet pipe 92 and outlet pipe 93. The width and intensity of the vortex flow depends on the pressure and the geometric shape of the output nozzle orifice. From physics we know that water is an incompressible fluid, which has a high anomalous heat capacity, a large kinematic viscosity, but has a good temperature controller. The feed mechanism of liquid, gaseous or solid chemical component is carried out at any stage of the technological process from the tank 31 or 36 through the dosing device 32 or 37 and then through the pipe 33 or 38 in the distribution unit 35 or 39.

In the manufacture of hydro-cavitation thermal heater for Autonomous systems Talon is bienia of small and average capacity must consider a number of specific features and construction details. For example, it is impossible to produce large branch lines from the hydro-cavitation thermal heater as a result of uneven heating of the mixture of water and air and strong heating of the local area hydro-thermal cavitation heater, where the very cavitation. It is necessary to isolate the shaft of the induction motor from the hydro-cavitation thermal heater heat coupling to the temperature hydro-thermal cavitation heater was not transferred to the asynchronous motor and did not reduce its efficiency, it is necessary to consider the behavior of a mixture of water and air at all stages move it by pipeline and hydro-cavitation heat the heater, the material of the blades, shaft material, the material support of the sliding elements, the material hardness, etc.

The invention allows to increase productivity, improve efficiency and extend the functionality of the hydro-cavitation thermal heater and use it as a pump, compressor, fan, mixing device to obtain a finely dispersed mixtures, for Autonomous heating systems, low and medium power, in ecology for the disposal of waste petroleum products and obtaining them from the combustion of fuel. This is the process can be described as a safe way of evaporation from the tank, where is the hydro-cavitation heater heat oil waste, and obtaining from them the furnace or lubricant. In the pulp and paper, chemical, food and other industries for grinding, heating, mixing, homogenization of multi-component systems. In health to obtain drugs in the form of aerosols, i.e. tiny solid and liquid particles dispersed in the air, as well as for military purposes. To reduce production costs, as well as review existing mathematical formula that can be applied now in hydrodynamics.
