Heat dissipation analysis and layout optimization of skid mounted module system of shale gas compressor

Abstract

Shale gas compressor is vulnerable to high temperature environment during operation. A large amount of waste heat generated during operation accumulates in the acoustic enclosure, resulting in overheating of motor, pipe, air cooler, etc., affecting the service life of key equipment and seriously threatening the safety of shale gas exploitation. Therefore, the DTY500 shale gas compressor was taken as the research object, a heat dissipation simulation model of the compressor skid mounted module system was established, the velocity field and temperature field characteristics were simulated, and the correctness of the simulation analysis method was verified by field experiments. Finally, the layout of the compressor skid mounted module was optimized. The results showed that most of the high-speed fluid did not cover the heat source areas such as the motor, compression cylinder and pipeline before the layout optimization of the air inlet and outlet, which was not conducive to the ventilation and heat dissipation of the equipment; after optimization, the relative heat dissipation of the system was increased by 46.34%, and the heat dissipation effect was significantly improved. The research results provide theoretical guidance for the optimization design of compressor skid mounted module system.
