泡沫灭火系统中泡沫比例混合装置在集输站库中的运行

Operation of foam proportioning devices for foam fire extinguishing system in gathering station library

泡沫灭火系统主要由消防水泵、消防水源、泡沫灭火剂储存装置、泡沫比例混合装置、泡沫产生装置及管道等组成。它是通过泡沫比例混合器将泡沫灭火剂与水按比例混合成泡沫混合液,再经泡沫产生装置形成空气泡沫后施放到着火对象上实施灭火的系统。泡沫灭火系统按泡沫产生倍数的不同,分为高、中、低倍数三种系统。文中重点对泡沫比例混合装置在油田大站大库中运行时存在的问题进行探讨。

The foam extinguishing system consists of fire pumps, fire water, foam extinguishing agent storage device, foam proportioning mixing device, foam generating apparatus and pipes and other components. The foam proportioner mixes foam extinguishing agent with water in a certain proportion to form a foam mixture, and then the air foam is generated by the bubble generating device and is expelled onto a fire. There are three kinds of foam fire extinguishing systems which are systems with high, medium and low multiples of foam acoording to the multiples of foam generated by the system. This paper discusses the problems created in the operation of the foam proportioning device in oilfield major stations and library.
