The invention relates to the field of operation of compressor stations of main gas pipelines, in particular air cooling machines.

At compressor stations of main gas pipelines as a means of cooling the gas and oil used air cooling units (ACU), which represent the heat exchangers according to the scheme "cross-talk" between the two environments is tsya organic and inorganic particles, which degrades the heat transfer in the environment.

The prototype is the air cooling unit comprising a heat exchanger unit, fan drive, supports, and system of a water irrigation [2].

The disadvantage of the prototype is that on the finned surfaces of the heat exchanger intensively precipitate hydrated organic and inorganic particles that impair heat transfer.

The objective of the invention is to increase the heat transfer rate.

The technical result from the use of the invention lies in the substantial intensification of the process of cooling the natural gas in air cooling units, maintaining their thermal parameters in time, improving the stress-strain state of the pipeline for compressor stations, reducing the risk of stress corrosion cracking under stress, improve technical and economic efficiency of the transport gas.

This is achieved in that the air cooling unit comprising a heat exchanger unit, fan drive, supports and systems of water irrigation, between the supports and the bottom plane of the unit heat exchangers installed frame with metal mesh and filter cloth, for example, from geotext smennymi pipes, jet barrel is directed from the top down and from the center to the perimeter, to jet the trunk attached air compressor, on the perimeter of the floor laid the tray with water.

The invention is illustrated in the drawing, in which the following notation: 1 - block heat exchangers; 2 - fan drive, 3 - bearing; 4 - water, 5 - frame; 6 - metal mesh; 7 - filter cloth, such as geotextile JSC "Komitex" (art. 1.300.160.03, 1.300.330.03 and so on), 8 - jet trunks with a slit with the tip located in a number of zigzag; 9 - air compressor; 10 - tray with water; 11 - metal wire.

In the air cooling unit comprising a heat exchanger unit 1, fan 2 with the drive supports 3 and water 4, between the supports installed the frame 5 with a metal grid 6 and the filter cloth 7, for example geotextile JSC "Komitex" (art. 1.300.160.03, 1.300.330.03 and so on), metal grid 6 by means of a metal wire 11 is electrically connected to the unit heat exchangers 1, jet barrel 8 with slot tip, oriented parallel to the plane of the frame, is directed from the top down and from the center to the perimeter, to jet the shaft 8 by means of the air compressor 9 the supplied compressed air, Peremohy 6 and the filter cloth 7 is installed on the bottom plane of the unit heat exchangers 1.

Proposed air cooler works as follows. When the fan 2 with the intensification of the cooling of the natural gas transported by the pipe 1 by wrapping them in an air stream having a lower temperature than the compressed natural gas. Air passing through the filter cloth 7 is purified from organic and inorganic impurities, which substantially reduced the contamination of the heat transfer tubes 1, which leads to the conservation of heat in time. Metal mesh 6 reduces the efforts of the air flow on the filter cloth and in electrical connection with the grounded heat exchanger 1 carries out the removal of static electricity from synthetic fabric. While smaller particles passing through the canvas, charged by static electricity, and push away from the heat exchange tubes, with a potential similar to the potential of synthetic fabric 7, which further reduces the intensity of contamination of the heat exchanger. At high ambient temperatures applied irrigation water. The jet direction of the trunk from top to bottom and from the center to the perimeter provides hydration vertical filter floor is the evaporation of water and cooling air. A supply of compressed air to the jet barrel 8 significantly intensifies the grinding water particles, the process of evaporation of water and cooling air is employed as the refrigerant in the AVO. The location of the jet drive shafts on each side in a series of zigzag creates overlapping zones of irrigation without crossing. The movement of water particles from top to bottom facilitates the involvement of small impurities passing through the filter cloth down and settling on the floor. The tray 10 with water contributes to the intensification of air purification from mechanical impurities. The filter cloth 7 installed on the bottom plane of the unit heat exchangers 1, picks up small particles of water. Here is the evaporation of water under the action of the air flow and the deposition of mineral particles in water, the fibers of the filter cloth, which can further enhance the cooling of the air mass and to protect the tubes from dirt dust and mineral substances, for example salts contained in water for irrigation. This in turn allows for irrigation use has not passed special training, particularly hard water.

Cleaning of the filter cloth from organic and inorganic plageman the invention allows significantly intensify the process of cooling the natural gas in the air cooling apparatus, to maintain their thermal parameters over time, to improve the stress-strain state of the pipeline for compressor stations, to reduce the risk of stress corrosion cracking under stress, improve technical and economic efficiency of the transport gas.
