Abstract

The invention discloses a high-humidity low-concentration dust generating device. The high-humidity low-concentration dust generating device mainly comprises an air compressor (1), an atomizing device(3), a sample gas heating device (6), a sample gas detecting device, a diluting heating device (16), other gas distributing device (17) and a flow control system, wherein the flow control system comprises a sample introduction flow control device (2), a sampling flow control device (14) and a diluting flow control device (15); and the sample gas detecting device is sequentially provided with an air outlet (10), an observation room (9), an air inlet room (7) and a waste liquor guide-out room (8) from top to bottom. According to the invention, an ultralow-emission dust removal process, especially mixed liquor atomizing design, is imitated, so that in comparison with dust preparation by conventional mechanical operation, operation stability is stronger; concentration controllability is stronger; dust grain size is more uniform; and concentration generation is more stable.

Description

technical field [0001] The invention belongs to the technical field of environmental detection equipment, and in particular relates to a high-humidity and low-concentration dust generating device. 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 conditions, online monitori...
