Background
In the existing fire retardant process of combustible gas, fire arresters are generally adopted. Flame arrestors for pipes are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. The flame arrester is installed on a pipe network for conveying or discharging inflammable gas, and is necessary safety equipment for preventing inflammable gas combustion explosion caused by backfire from spreading to the whole pipe network.
Flame arresters currently exist in several forms, in terms of flame arresting structures, elements and forms: corrugated plate, filling type, parallel plate type, wire mesh type, porous plate type, etc. 5 kinds of non-water-sealed flame arrestors and water-sealed flame arrestors.
The main advantages and disadvantages of the existing non-water-sealed flame arrester are as follows: the structure is simple, the investment and maintenance cost is low, and the fire retardant effect is better; however, in the case of high content of impurities or salts in the combustible gas, the flame arrester is prone to blockage, and needs to be cleaned in time, and if a spare flame arrester is not installed, the use or discharge of the combustible gas needs to be stopped, which affects production.
The water-sealed flame arrester has a more complex structure than a non-water-sealed flame arrester, and has large investment and occupied area, but the phenomenon of blocking of the flame arrester due to impurities in combustible gas or high salt content is not easy to occur. And because the gas of the water-sealed flame arrester enters a gas using point or an exhaust point after passing through the water seal, part of moisture is included in the gas, which is not beneficial to subsequent combustion.
The combustible gas which is inflammable and explosive is sent into the water seal type flame arrester before being burnt, so that the burning efficiency is reduced and the energy generated by burning is wasted because the moisture in the combustible gas and the moisture brought out from the water seal enter a burning system while the burning or the explosion is prevented.
