Cartridge filter for desulfurization slurry pump outlet of thermal power plant and operation method thereof
By simplifying the structure and operation, a cylindrical filter with a conical positioning surface and a cover plate plane is used to fix the filter screen. This solves the problems of complex structure and poor reliability of existing cylindrical filters at the outlet of desulfurization slurry pumps in thermal power plants, and achieves the effects of extended filter screen life, high rubber lining reliability and high filtration efficiency.
