WITH

The invention relates to air coolers (ABO) for gas of compressor stations (CS) and can be used for cooling gas in gas-lift CS, compressor stations for cycling process, as well as in stations for transporting natural and petroleum (associated) gas.

Air coolers KS are known that contain heat exchangers, fans enclosed in a casing, suction and recirculation chambers, in which the recirculation system is made by means of bypass channels for suction of the recirculation chamber of thermal air and supplying it to the suction fans.

Performing additional bypass channels significantly increases the metal consumption and complicates the design of the ABO.

The closest to the claimed air-cooled gas cooler is

An air cooler containing a suction chamber with louvers, through which air is taken by fans and fed to heat exchangers, a recirculation chamber with louvers, from which warm air is sucked by reversible fans in recirculation mode and fed to the suction side camera on mixing. In this case, the fan drives have an autonomous cooling system.

The disadvantage of this ABO is uneconomical (operation of fans specifically for supplying warm air for mixing into the suction chamber).

The aim of the invention is to increase the reliability and efficiency of the ABO in the recirculation mode.

In order to achieve this goal, the compressor’s air cooler’s gas cooler, including heat

rechargers located in a single housing, a re-use up-camera with drive louvers, reversible fans with blown drives, placed one in each suction chamber, additionally contain hinged boxes placed at the entrance of the suction chambers with the possibility of formation in recirculation mode heated air flow channel from one suction chamber to another.

The installation of hinged ducts provides for the formation of a directional flow of heated air drawn from heat exchangers by fans working in reversing mode (recirculation mode) and supplying it to the mixing of cold air drawn in through the suction chamber of stopped fans.

The inventive air-cooled gas compressor KS possesses the following distinctive features; gas cooling in the recirculation mode is carried out by sucking hot air from the heat exchangers and feeding it into the suction chamber of the stopped fans through the channels formed by ducts, which does not require additional energy and design costs and increases the efficiency and efficiency of the air cooler CS in recirculation mode .

The proposed apparatus is shown schematically in the drawings, where FIG. 1 shows the cooling of the gas in the normal operating mode; Fig. 2 illustrates gas cooling in recycle mode; FIG. 3 shows an autonomous cooling system for fan drives; figure 4 - installation of folding boxes in the summer time; Fig 5 - the position of folding boxes in the cold period of time.

The air cooler gas KS containing heat exchangers 1; reversible fans 2 enclosed in housings 3 and fitted with shells 4 of drives (electric motors) 5, forming suction chamber A with folding boxes 6 installed at the inlet (figure 4, figure 5), while fans 3 are mounted on supports 7 with channels B for exhausting the air cooling the drive 5 of the fan 2; a recirculation chamber 8 with driven louvers 9 from the actuator 10 by means of a lever system 11.

AVO gas KS works as follows.

In the normal mode of gas cooling, the fans 2, sucking the air from the environment through the suction chamber A, blow the heat exchangers 1 and release the heated air through the louvers 9 of the recirculation chamber 8 to the atmosphere. In this case, the drives (electric motors) 5 of the fans 2 are cooled independently of the standard fans, exhausting air through the channels B of the supports 7 to the atmosphere.

In the recirculation mode, part of the fans 2 is stopped, and the rest work in the reversing mode, taking the heated air from the heat exchangers 1. At the same time, the louvers 9 of the recirculation chamber 8 are fixed by means of the actuators 10 and the lever system 11 in a position that allows the cold air to mix suction fans 2 from heat exchangers 1, after which the heated air is supplied to the cooling of heat exchangers 1 (to the suction of fans 2 operating in reversing mode), after which hot air is drawn in into the suction chamber fans stopped by channels formed boxes 6, which is admixed to the cold air, and enters the heat exchanger 1, which is discharged after passing into recirculating chamber 8 where it is mixed with cold air to room recirculation.

Such a constructive implementation of the AVO gas KS increases the efficiency and reliability of cooling, simplifies the design and reduces the metal consumption.
