Description

 The invention relates to techniques for the destruction of bacterial shells by hydrodynamic, cavitation and thermal effects and can be used in heating systems of residential and industrial buildings, structures.

 Known disintegration installation comprising a housing with suction and discharge nozzles, a rotor located along the axis of the housing, made with alternating protrusions and depressions interacting through the annular channel with the protrusions and depressions of the housing, the disadvantage of which is the low degree of transition of high-speed and static pressures during their multiple transformations in thermal, which reduces the effectiveness of its use in heating systems.

 The purpose of the invention to increase the efficiency of the installation is achieved by the fact that the protrusions and depressions are made in the form of an elastic strip located on the side surface of the housing, with cells, the volume of which increases from the discharge pipe to the suction.

 The cavitation phenomenon is generated by the condensation of microbubbles of steam, which form steam voids, and the centers of condensation are bacteria, and in heating systems, in particular, iron bacteria, the greater the disunity of the cells, the more foci of collapse of microbubbles, and correspondingly more sections of the transition of high-speed pressure into static and vice versa, and part of the pressure energy goes into heat, providing heating of the working fluid. Moreover, at the suction nozzle, where in the annular channel the velocities of the incoming working fluid are small, the transformation process itself is predominant, and therefore the cells have a larger volume than the cells at the discharge nozzle.

 In FIG. 1 shows the installation, a longitudinal section; in FIG. 2 is a view along arrow A in FIG. one; in FIG. 3 installation diagram in the heating system.

 The disintegration installation comprises a housing 1 with a suction 2 and discharge 3 nozzles, a rotor 4 located along the axis of the housing 1, made with alternating protrusions 5 and depressions 6, interacting through the annular channel 7 with the protrusions and depressions of the housing 1, made in the form of a strip 8 located on the side surface of the housing 1, with cells 9, the volume of which increases from the discharge 3 to the suction 2 nozzles of the housing 1. In the heating system, a supercharger 11 is installed in parallel with the disintegrator 10, and their connection to the system e is carried out through valves 12, 13, 14 and 15 of thermostat 16. The disintegrator 10 is mounted on an elastic support 17 and communicate with the system via elastic elements 18.

 Disintegration installation works as follows. The working fluid, for example water, enters through the nozzle 2 into the annular gap 7, in which it undergoes hydrodynamic influences, in particular, it is ejected from the cavity 6 and enters into the cells 9 of the strip 8, in which the fluid decelerates and the high-speed pressure is transformed into static and at a higher static pressure, the liquid is absorbed into the next cavity 6 and is repeated many times with increasing static pressure in the cells 9. When the liquid is sucked from the cells 9 in the latter there is a vacuum, local boiling the formation of microbubbles, which condenses the new portions of the liquid. During condensation, with bacteria being the centers of condensation, liquid rushes into the voids and destroys the shells of bacteria. With multiple transitions of pressure, high-speed to static and vice versa, part of the pressure energy goes into heat. To exclude vaporization in the entire volume of the liquid, the temperature relay switches off the disintegrator 10 through switching the shut-off valves 12, 13, 14 and 15 and switches on the supercharger 11, in which there are no cells 9, as a result, the temperature of the working fluid decreases and the disintegrator 10 is turned on via the temperature relay 16 .

 The use of a disintegration unit eliminates the biological fouling of pipelines and heating devices, respectively, the hydraulic resistance decreases, and the heat transfer coefficients increase. Local heating systems eliminate the need for heating pipelines from the CHP. The system becomes mobile and responsive to changes in temperature in the house or premises, increases the service life of materials.
