Wet dust removal device for steelmaking slag braising smoke dust

Abstract

The utility model discloses a wet dust removal device for steelmaking slag braising smoke dust, and belongs to the technical field of smoke dust treatment. The device comprises a trapping cover, a dust removal vertical pipe, a dust removal inclined pipe, a wet dust remover, a fan, a chimney, a main water supply pipe slag braising pool and the like. The components 1-20 form a flue gas dust removalsystem, and an integrated three-stage wet-type filtration efficient dust remover technology is adopted; and a water supply system is used for meeting the metal water film filtering water supply requirement of the fine filtering section of the wet dust remover and the fan impeller cleaning water supply requirement. The device has the following advantages: the integrated three-stage wet-type filtering efficient dust remover technology is adopted to carry out the wet-method dust removal process on steelmaking braised slag water-containing smoke dust, the problem that dust emission of a conventional wet-method dust removal system cannot reach the standard is solved, the water resource quality-divided recycling technology is adopted, the water consumption is reduced, the operation cost is reduced, zero emission of sewage is achieved, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of smoke and dust control, and in particular relates to a wet dust removal device for steelmaking slag smoke and dust. Background technique [0002] The smoke and dust produced by the steelmaking slag process, the main components are: CaO, SiO 2 , MgO, S, MnO and other particulate dust and a large amount of water vapor. At present, many enterprises adopt unorganized emission, which causes fog to diffuse in the slag crossing area, which seriously affects the atmospheric environment. At the same time, the diffuse water vapor corrodes the steel structure, posing safety hazards. [0003] At present, the Ministry of Ecology and Environment's "Steel Enterprise Ultra-Low Emission Transformation Work Plan (Draft for Comment)" requires all new (including relocation) steel projects to reach ultra-low emission levels, and the ultra-low emission limit of dust particles is required to reach ≤10mg / Nm3 ; By the end of 202...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a wet dust removal device for steelmaking slag dust, which solves the problem that the dust discharge cannot meet the standard when adopting fugitive emission and conventional wet dust removal technology, shortens the process flow of the dust removal system, and reduces the occupation. At the same time, the quality and recycling of water resources is carried out to reduce water consumption, reduce operating costs, realize "zero discharge" of sewage, and reduce environmental pollution
