页岩气压缩机撬装模块系统散热分析及布局优化

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

页岩气压缩机在工作时易受到高温环境的影响,产生的大量余热积聚在隔声罩内,导致电机、管道、空冷器等过热,影响关键设备的使用寿命,严重威胁页岩气开采安全。因此,以DTY500型页岩气压缩机为研究对象,建立了压缩机撬装模块系统的散热仿真模型,开展其速度场和温度场特性仿真研究,并通过现场实验验证了仿真分析方法的正确性,最后对压缩机撬装模块进行布局优化。结果表明:进排风口布局优化前大部分高速流体并未覆盖电机、压缩缸、管道等热源区域,不利于设备的通风散热;优化后,系统的相对散热量提高了46.34%,散热效果显著提升。研究结果为压缩机撬装模块系统的优化设计提供了理论指导。

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.
