低浓度瓦斯输送管路发生爆炸燃烧事故或发电机组因故停机时,势必造成瓦斯输送管路堵塞,瓦斯抽放泵站出现憋泵情况,直接影响到煤矿生产安全。阻火式超压放散装置利用水封原理在输送管路压力超过设定值时自动放散,避免出现憋泵;另外该装置还具有阻火功能,提高了抽放系统的安全性。介绍了阻火式超压放散装置的方案设计;详细说明了装置的结构设计和水位自动控制系统设计。
Low concentration gas pipeline explosion occurred combustion accident or genset shutdown, it is bound to result in gas transmission pipeline blockage, gas pump pumping stations appear Case directly affect the safety of coal production. The fire-retardant overpressure diffusing device utilizes the principle of water seal to automatically dissipate when the pressure of the delivery pipeline exceeds the set value, so as to avoid the occurrence of a hold-up pump. In addition, the device also has a fire-blocking function to improve the safety of the drainage system. The scheme design of fire retardant overpressure diffusing device is introduced. The structure design of the device and the design of automatic control system of water level are described in detail.
