Description

technical field [0001] The invention belongs to the technical field of environmental protection detection equipment, and in particular relates to a dust generation device and method with controllable concentration. Background technique [0002] With the development of my country's economy and the adjustment and transformation of industrial structure, the environmental pollution problems caused by pollution sources such as industrial boilers, power plant boilers and industrial kilns have become more and more prominent, among which dust pollution is particularly serious. In recent years, the "ultra-low emission" transformation of domestic coal-fired power plants has been gradually implemented. The control of dust is mainly through bag dust removal (or electric dust removal) in conjunction with wet desulfurization and wet electric dust removal processes, resulting in low concentrations of dust emissions from domestic pollution sources. , High humidity compound working condition...
