Problems solved by technology

[0003] Although the polyaluminum chloride production boiler system can achieve energy saving and consumption reduction and reduce dust emission to a certain extent, the dust removal effect of the desulfurization and dust removal device on the flue gas is not ideal, resulting in the final flue gas discharged from the high-altitude chimney Contains dust, causing certain environmental pollution, unable to meet the requirements of use
