Flue gas treatment requires desulfurization and denitrification, which requires the use of desulfurization and denitrification equipment. The wastewater generated by the desulfurization and denitrification equipment spraying will be filtered to obtain desulfurization and denitrification gypsum. In order to save resources and avoid waste, the desulfurization and denitrification gypsum waste will be collected and utilized.

[0003] When filtering wastewater, the waste collection device used in the existing desulfurization and denitrification equipment only filters through a single filter screen. The filter screen is easily blocked by the desulfurization and denitrification gypsum, which affects the filtering effect. In addition, the filter screen is generally set to be detachable. After the filtration is completed, the filter screen is manually disassembled, the desulfurization and denitrification gypsum on the filter screen is collected, and then installed, which is time-consuming, labor-intensive and inefficient.

[0004] To this end, we propose a waste collection device for desulfurization and denitrification equipment. Utility Model Content
