Gas filtering system

气体过滤系统

Abstract

The utility model discloses a gas filtering system. The system comprises a gas filter, wherein a gas inlet of the gas filter is connected with a gas inlet pipe of gas to be filtered; an exhausting hole of the gas filter is connected with a filtered gas exhausting pipe; the gas inlet pipe and the exhausting pipe are provided with bent pipe sections respectively; each bent pipe section is provided with a liquid inlet and an overflowing hole along a gas conveying device; each overflowing hole is higher than each liquid inlet so that liquid pressure between each overflowing hole and each liquid inlet is greater than gas inlet pressure of each bent pipe section when liquid is injected into the bent pipe section; a liquid discharging hole is further formed in the bottom of each bent pipe section; and valves are arranged on the liquid inlets, the overflowing holes and the liquid discharging holes respectively. With the adoption of the system, cutting-off devices connected onto the gas inlet pipe and the exhausting pipe of the gas filter are improved so that the gas filtering system is prevented from a condition that the system cannot work normally and the anti-leaking performance is relatively good.
本实用新型公开了一种气体过滤系统,该系统包括气体过滤器,所述气体过滤器的进气口连接待过滤气体进气管,气体过滤器的排气口连接已过滤气体排气管,所述进气管和排气管上分别设置有弯曲形管段,所述弯曲形管段上沿气体输送方向分别设置有进液口和溢流口,所述溢流口的高度高于进液口的高度从而当从所述进液口向该弯曲形管段中注入液体后使进液口与溢流口之间的液体压力大于该弯曲形管段的进气压力,弯曲形管段的底部还设有排液口,所述进液口、溢流口以及排液口上分别设有阀门。该系统对连接其气体过滤器的进气管以及排气管上的切断装置进行了改进以防止其无法正常工作且防泄露更好。
