Oxygen compressor system for purifying methanol feed gas

The utility model provides an oxygen compressor system for methanol feed gas purification, which comprises multiple stages of oxygen pressure units, each oxygen pressure unit comprises a buffer tank, the buffer tanks on two adjacent stages of oxygen pressure units are communicated, a plurality of support columns are mounted at the bottoms of the buffer tanks, and elastic buffer blocks are arranged on the support columns. Vibration generated in the working process of the oxygen compressor system can be buffered and weakened through the elastic buffer block, and the situation that pipelines, elbows and safety valves on oxygen compressor accessory equipment are damaged and leakage points occur due to vibration of the buffer tank can be effectively prevented. 本实用新型提出了用于甲醇原料气净化的氧压机系统，其包括多级氧压单元，氧压单元包括缓冲罐，相邻两级氧压单元上的缓冲罐连通，缓冲罐的底部安装有多根支撑柱，支撑柱上设置有弹性缓冲块。通过弹性缓冲块可对氧压机系统工作过程中产生的振动进行缓冲、弱化，可有效防止因缓冲罐振动对氧压机附属设备上的管道、弯头以及安全阀造成损坏并出现漏点的情况。
