Problems solved by technology

[0006] The above method can achieve a certain removal effect on dust particles and harmful gases in the exhaust gas, but these removal equipment occupy a large area, have insufficient stability, and complex processes, resulting in high maintenance and operating costs, and cannot be achieved once for high-concentration smoke and dust. In general, multi-level composite treatment is required for permanent removal; and in the process of dust removal, because the filter bag used in the existing dust removal technology is designed with seams, part of the dust will leak from the gap, which has a certain impact on the removal effect. It is difficult to stabilize the processing capacity of PM0.1-2.5MM above 85%
