Waste gas from oily wastewater treatment equipment: flame arrester clogged
Thread Content
Basic process: Oil-containing wastewater is subjected to air flotation; the exhaust gases from the related wastewater tanks are collected and sent to the incinerator. The process involves air flotation, a flame arrester, an alkaline scrubber tower, a buffer tank, another flame arrester, a fan, yet another flame arrester, another buffer tank, yet another flame arrester, and finally the incinerator. Current issue: Due to cost considerations, the original design specified carbon steel for the exhaust gas collection pipes; flame arresters are installed at the inlet and outlet of the fans, at the inlet of the incinerator, and in the exhaust gas collection area. The current problem is that the flame arrestor is severely clogged, and replacing it with a stainless steel pipe is too costly, making it impractical. Discussion: Are there any simple and inexpensive solutions? Is it possible to use a water seal to replace part of the flame arrestor? If so, what are the requirements for the water seal?
Consider cleaning the flame arrester regularly to reduce clogging, or look for cheaper alternatives to the flame arrester. It is feasible to use a water seal in place of part of the flame arrestors, but the specifications and requirements for such a water seal need to be determined based on the specific composition of the exhaust gases and the handling requirements, in order to ensure safety and effectiveness. .
It has already been answered upstairs; I’ll add that the wire mesh inside the flame arrester is clogged, so it needs to be removed and cleaned
The problem is that it can’t last even a week; it’s too troublesome!
It is possible to detect the LEL concentration of exhaust gases, and by increasing the dilution air, the concentration of organic substances can be reduced； Install a flame arrester near the incinerator ； Prevent tempering inherently. All these flame arrestors are merely passive measures after backfire.
First, determine whether the explosion protection rating of the flame arrester is over-designed, resulting in too small gaps in the flame arrester disc
This blockage is probably caused by dust. There seems to be a sonic soot blower; maybe turning it on and using the vibrations of sound waves to blow away the soot would work? I’m not sure though
