moistened with the fluid supplied by pump 10 to the perforated coil pipe 8. The vapor-gas mixture formed in layer 7, before being released into the atmosphere, enters the cyclone (C) 14 through pipe 16 to supply steam. The outer walls of C 1A, placed in housing 12, are cooled by evaporating the liquid from layer 15 of a capillary-porous material that crushes the outer wall of C 14. In C 14, the vapor-gas mixture is twisted by a swirl 23, cooled, the steam condenses, and distillate t enters the tank 11, and the lean gas-vapor mixture through the bump 24 through the pipe 21 by the fan 22 is released into the atmosphere. 1 il.

The invention relates to the technological equipment of the microbiological industry and can be used in installations for cooling liquid nutrient and culture media.

The purpose of the invention is to reduce energy consumption and enhance functionality.

j The drawing shows the proposed installation of cooling liquid CD, general view.

The installation for cooling a fluid comprises a heat exchanger housing 1 with an air intake 2 and a filter 35 times a tubular coil 4 in it for cooling a fluid with nozzles 5 and 6, respectively, for introducing and withdrawing fluid, covered with a layer 7 of capillary-porous material of variable thickness, perforated with a serpent A pipeline 8 with a dead end 9 and a pump 10. The coils of the pipeline 8 are located under the coils of the coil 4. The installation contains a capacity of 11 D.PL of distillate collection.

The device for vapor condensation contains a cyclone 14 installed in the casing 12 with the formation of an annular gap 13, the casing wall of which is on the outer side covered with a layer 15 of capillary-porous material.

The cyclone body 14 in the upper part is communicated by a pipe 16 for supplying steam to the heat exchanger body 1a in the housing 12 above the cyclone body.

communicated with tank 11 for collecting distillate. In the lower part, the casing 12 has a pipe 19 for draining coolant, and in the upper part the casing 12 is connected by a pipe 20 with a pipe 16 for supplying steam, a cyclone 14 by a pipe 21 is in communication with a fan 22 and has a single swirler 23 and a baffle 24. Capacity 11 for collecting distillate is provided with a nozzle 25 with stop valves. Under the filter 3 and the air intake 2 is mounted a container 26 for coolant with a pipe and valves 27.

The installation works as follows

A cooled liquid with a temperature of 60–160 ° C is fed to the tubular coil 4 of the heat exchanger through the nozzle 5. To remove heat, the capillary-porous layer 7 of the coil 4 is moistened with the help of the fluid supplied by the pump 10 to the perforated coil pipe 8. As a result of the phase transition steam is formed, which is sucked out of the heat exchanger 1 by the fan 22. The vapor-gas mixture before it enters the atmosphere enters the vapor condensation device containing the cyclone 14 through the steam supply pipe 16. At the same time, the outer walls of the cyclone are cooled by the fluid supplied by pump 10 through conduit 18 due to evaporation of fluid from the capillary-porous layer 15 of the material moistened from the fixture 17. In the cyclone 14, the vapor-gas mixture is twisted by a swirler 23, heat exchange with the elements cooled by vapor liquid vapor

is condensed and the distillate enters the tank 11, and the lean gas-vapor mixture through the baffle 24 through line 21 by the fan 22 is emitted into the atmosphere.

The proposed plant for cooling a liquid reduces energy consumption and expands functional capabilities by reducing the flow rate of the cooling medium while obtaining distillate.
