Material of the foam catcher: first suction, second suction
Thread Content
What is the material used for the dry absorber and the foam trap in the second absorber – tetrafluorine fiber or glass fiber?
This might vary depending on the manufacturer; the materials used could also be different! Previously, when we were working on the sulfuric acid project, the only suggestion given was to use “fiber mist removal elements”. You could contact Xin Hongda; they produce many such products, and I think they will be able to provide you with the answer you’re looking for. (Moderators, please don’t punish me – I swear this is not an advertisement.)

Early absorption towers used a foam-trapping layer made of PTFE mesh. Later, due to the increased operating intensity of the absorption tower, the amount of mist entrained rose, so a cylindrical demister was introduced; the fiber bed was made of glass fibers.
:Handshake: Handshake. What’s the material used in Meng Moke’s product after one or two sucks? Is it fiberglass or PTFE?
It is said that abroad, tetrafluoro membrane stacks are used in place of tetrafluoro wire meshes, with a demisting efficiency of over 99.7%. They offer excellent corrosion resistance as well as outstanding demisting performance; I wonder if anyone has seen them in use.
