[0002] In the existing process, the concentrated water produced in sewage treatment contains chemical elements such as Fe, P, Al, Ca, Cd, Co, Cr, Cu, K, Mg, Mn, Na, Ni, Pb, Tl, Zn, N, and Li. It is concentrated into concentrated liquid through high-pressure reverse osmosis and then produced into finished ammonium sulfate through MVR multi-effect evaporation.

[0003] Before the concentrate enters the MVR multi-effect evaporator, it needs to be heated by a plate heat exchanger before entering the multi-effect evaporator. Because the concentrate contains various chemical elements, the plate heat exchanger is blocked and scaled, the flow rate is reduced, the energy consumption is increased, and the workshop needs to be stopped for cleaning after the blockage, which increases the workload of employees and reduces the output of finished products. Therefore, it is necessary to design an ammonium sulfate concentrate processing device that can effectively filter the concentrate and will not cause the workshop to stop when cleaning the filter cartridge to solve the above problems.
