Acid resistant hot filtration
Thread Content
Talents engaged in chemical equipment, take a look at the following situations and see what tips you have: The material is acidic and requires hot filtration, but the general hot filter is made of stainless steel. I looked online and found that there are few enamel hot filters with jacketed insulation for sale, or equipment with the same function. This may be a business opportunity! If anyone knows, please feel free to tell me!
Acid-resistant non-metallic filter materials include polypropylene, but polypropylene can only be used below 90 degrees. PTFE can withstand a certain temperature, but the filtration accuracy is too high, and the coarsest one is only 4-5U. If the shell is jacketed, considering the heat transfer effect, it should be made of metal, right? It's best to make your requirements clearer, such as how to grow the medium, temperature, pressure, flow rate, and filtration accuracy. Someone may be able to help you.
The microporous ceramic filter can be tailor-made according to the pore size and flow rate of the material. The ceramic filter has strong acid resistance and high temperature resistance. The pressure loss is 0.5 kg and the heat transfer effect is good.
Do ceramics conduct heat well? Never heard of it. . . . .
My material is an organic substance with two carboxylate groups, which appears red when exposed to stainless steel. It can be dissolved in hot water with pH=1 at 93 degrees Celsius, and will precipitate when cooled to 85 degrees Celsius. Activated carbon is required for decolorization. As we all know, if there is product precipitation, it will clog the filter paper, so it must be kept warm. I wonder if you prawns have any clever tips?
I have an idea, but I don’t know if it is mature, and there are still many things I don’t understand about your situation, so I need to discuss it with you. If it is convenient for you, please call me at 13917574010 Mr. Tian.
Thank you, Brother Tian. I have recently found a solution. It is not filtering under acidic conditions, but under alkaline conditions. The effect is okay. Thank you for your help.
Back to the fourth floor: Ceramics will indeed lower the temperature of the medium at the beginning, but after a few minutes of operation, the filter element will no longer lose heat.
My company also has a ceramic filter, which is only used for cold filtration. I think the ceramic may be more effective if it is preheated in advance.
