Is it necessary to install an explosion vent in an activated carbon adsorption box for exhaust gases?
Thread Content
I heard that an explosion vent needs to be installed in the activated carbon adsorption box for exhaust gases; the only reason I can think of is that the activated carbon might catch fire, causing the internal pressure to rise, and thus an explosion vent is necessary. But it seems a bit far-fetched. So let’s discuss whether it’s necessary to install an explosion vent; personally, I don’t think it’s needed.
During use, exhaust gas activated carbon adsorption units may experience some abnormal conditions, such as the activated carbon catching fire or an increase in internal pressure. These problems can lead to the explosion or damage of the adsorption box; therefore, when considering safety issues, some factories or enterprises may choose to install explosion venting devices in the activated carbon adsorption boxes for waste gas to ensure safety. However, whether a blast relief device is necessary depends on the specific process and working environment. If the activated carbon used in the exhaust gas adsorption box is relatively safe, and no abnormal conditions such as high temperatures or pressures occur under normal operation, then there is no need to install an explosion venting device. However, if the activated carbon used is prone to catching fire or may cause an increase in pressure inside the box under certain conditions, an explosion venting device must be installed in the exhaust gas activated carbon adsorption box. Therefore, we recommend that when using exhaust gas activated carbon adsorption units, an assessment should be conducted based on specific circumstances to determine whether it is necessary to install explosion relief devices, in order to ensure the safe and stable operation of the production process. .
Organic gases adsorbed by activated carbon might explode, right, regarding what is being adsorbed?
This requirement is not specified in the \"Technical Specifications for the Treatment of Industrial Organic Waste Gas by Adsorption Method\" (HJ2026-2013)
It is not necessary; the activated carbon box requires cooling and fire suppression capabilities.
There’s no need for explosion venting, right? After the activated carbon absorbs the substances, they’re usually just discharged
The concentration of flammable and explosive gases entering the activated carbon adsorption unit for exhaust gas must be below 25% of the lower explosion limit
Only low-concentration waste gas can enter; high-concentration gas is highly flammable.
