Is there a hot gas pipe in the room that needs to be led outside for venting? Can it be vented directly, or is it necessary to use a fan to dilute the gas before venting it?

Is there a hot gas pipe in the room that needs to be led outside for venting? Can it be vented directly, or is it necessary to use a fan to dilute the gas to levels below its explosive limit before it can be released? ? ?

Some can be discharged directly, while others cannot. Could you tell me the name of your combustible gas?

So how can we distinguish this modification? ? Since it is a gas generated during the wastewater treatment process, its composition is quite complex; it contains oxygen, ammonia nitrogen, volatile phenols, flammable gases emitted from tar, hydrogen sulfide, and other substances, all of which are produced during the hydroprocessing of tar-containing wastewater

Well, that’s called exhaust gas; you need to collect and treat it, as it can’t be released directly into the air. I thought it was a single category of substance.

Hydrogen is discharged directly; a flame arrester must be installed on the discharge pipes, and lightning rods are required at high points. Your exhaust gas needs to be treated

So if only hydrogen is being released, is it still necessary to use a fan to reduce the hydrogen concentration below its explosive limit before releasing it? ? Can it still be emitted as long as it is within the explosion limit?

Regarding your question, it is recommended that you follow the provisions of 5.5.11 in the \"GB 50160-2008 Code for Fire Protection Design of Petrochemical Enterprises\". For your reference

According to current environmental regulations, the exhaust gases generated from wastewater treatment cannot be released directly, nor can they be released after dilution; they must be treated before being discharged. You might want to find out about the local environmental regulations.
