Problems solved by technology
[0003] If the flue gas enters the demister system directly after cyclic absorption, it will cause problems such as blockage of the demister. The specific manifestations are: 1. There are many impurities in the cyclic absorption liquid. Effective removal of aerosol; 2. Improper operation will easily cause blockage of the demister; 3. The dust content at the outlet is too high to meet the requirements of future environmental protection standards

Description
technical field [0001] The invention relates to a purification device, in particular to an ultra-low emission purification device, which belongs to the field of environmental protection. Background technique [0002] The traditional ammonia desulfurization process includes ammonia addition system, circulation system, oxidation system, ammonium sulfate post-treatment system, and purification and demisting system. [0003] If the flue gas enters the demister system directly after cyclic absorption, it will cause problems such as blockage of the demister. The specific manifestations are: 1. There are many impurities in the cyclic absorption liquid. Effective removal of aerosol; 2. Improper operation may easily cause blockage of the demister; 3. The dust content at the outlet is too high to meet the requirements of future environmental protection standards. [0004] Therefore, it is an urgent technical problem in this technical field to provide an ultra-low emission purificatio...
