Description

technical field

[0001] The invention relates to a dust removal device, in particular to a dust-laden steam flow flue gas wet-type high-efficiency dehumidification and dedusting device for air pollution prevention and control, which belongs to the technical field of flue gas dedusting, desulfurization and purification devices, and can also be used in gas cooling and dehumidification systems . Background technique

[0002] The iron and steel industry is the basic industry of modern economic construction and modern national defense. It is also a large resource and energy consumer. At the same time, a large number of by-products and pollutants are produced in the production process. The task of energy conservation and emission reduction is urgent and heavy. In terms of air pollution control, on February 27, 2013, the state decided that steel, cement and other industries would implement special emission limits for air pollutants at different times. Strengthen the control of inha...
