High filter pressure difference

Remove the filter element and clean it manually (using high-pressure water).
Please clean the filter element. A coarse filter can be added in front.
If it’s temporary, you can temporarily switch to a 50μ filter element to find out the cause of the blockage
80um is sufficient for quench water; 25um is too fine and prone to clogging
The filter has been modified into an auto-cleaning filter
It’s still 100um at the moment; not much has changed. The range of the differential pressure gauge is 20 kp – is the range of this gauge too small?
The range of the differential pressure gauge is indeed a bit small; it should be around 50 KPa. Are yours also automatic backwash filters? Find out whether the reason is insufficient hydrogenation in the hydrogenation reactor or poor operation of the upstream system, which results in dirty exhaust gas entering the quench tower
The hydrogen was in excess and caused a fire; there was no automatic backwashing, and the operation remained relatively stable
It’s not automatic backwashing; we always have an excess of hydrogen, and the previous system is also working normally
