Regarding fans

This post was last edited by sunjl1981 on 2013-1-6 at 22:39. The fan used for removing contaminants creates negative pressure; is it really necessary to maintain negative pressure? Why would positive pressure cause chlorine to leak? Can’t the gas stay inside a pipeline with negative pressure?? # + +
Reply to 1# True Man: Has your company started production so quickly? Theoretically, gas will flow as long as there is a pressure difference, but since there is pressure in the pipe, chlorine will definitely flow out from the end of the pipe where there is no pressure. It’s the same as electric current – it flows first through the resistor with the lowest resistance: lol You know this! They didn’t even say anything when they changed the phone number
Reply to 2# wqhhdiaodu: It seems I understand now. Setting it to a negative pressure is intended to ensure a proper chlorine-hydrogen pressure difference during startup and shutdown; that’s why it’s best to maintain negative pressure for harm control. I guess it would also work if positive pressure is used instead. These are all my small accounts; what’s your full account number? You’re too reluctant to tell me it, what can I do?
Reply to 4# renzongkai: The chlorine system operates under slight negative pressure; therefore, an accident scenario also requires operation under negative pressure.
Negative pressure operation can prevent chlorine leaks
The exhaust system requires negative pressure. Some devices are connected to exhaust gas.
