我厂发动机油封在试车过程中产生大量油雾。最初该车间仅安装一根自然通风管将含油气体直接排至室外,效果很差。室外地面布满了油迹,连草都不生长,周围环境污染严重,能源浪费,而且火灾很容易发生。为了解决这一实际问题,当初在无专用产品可资选用情况下,拟用铬酸净化回收器代替,期望通过分离空气中的油雾,达到回收润滑油的目的。但从该没备的资料情况看, Our engine oil seal produced a lot of oil mist during the test run. Initially, the shop installed only a natural draft tube to drain the oily gas directly to the outside. The effect was poor. The outdoor ground is full of oil traces, and even the grass does not grow. The surrounding environment is seriously polluted, energy is wasted, and the fire easily occurs. In order to solve this practical problem, it was originally intended to use chromic acid purifiers instead of alternatives in the absence of special products. It is hoped that oil mist can be separated from the air to achieve the purpose of recovery of lubricating oil. However, from the situation of the unprepared data,
