Defluorination and desulfuration dust removal device and technology

Abstract

The invention relates to a defluorination and desulfuration dust removal device and technology. The defluorination and desulfuration dust removal device comprises a shell, a gas inlet, an atomization throat, a swirl chamber, a swirl plate, a liquid stopping plate I, a spraying nozzle, a defogger, a liquid stopping plate II and a gas outlet. The defluorination and desulfuration dust removal technology comprises the steps of mixing dust-containing gas with water in a gas inlet chamber to settle down dust in the gas and remove components such as hydrogen fluoride and sulfur dioxide; introducing atomization liquid into the swirl chamber, atomizing and spraying the gas by the spraying nozzle to further remove fluorine and sulfur as well as the dust; inputting the atomized gas subjected to dust removal into a gas exhaust chamber, removing water fog in the gas after passing through the defogger and the liquid stopping plates, and discharging the gas through the gas outlet, wherein the removed water fog forms absorption liquid which is recycled by a circulating pump. According to the defluorination and desulfuration dust removal device and technology, the dust in post-treatment equipment is greatly reduced, and the reliable running of the post-treatment equipment is guaranteed; meanwhile, the device and the technology are convenient to operate and maintain, and the defluorination and desulfuration dust removal effect on the dust-containing gas is enhanced.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to a defluorination, desulfurization and dedusting device and process for purifying dusty gas. Background technique [0002] The backwardness of flux exhaust gas treatment technology in our country has caused the situation of flux exhaust gas pollution to be still very severe. The waste gas generated during the production process of smelting flux belongs to fugitive emission, and the waste gas contains dust. In addition, it also contains: carbon dioxide, sulfur dioxide, sulfur trioxide, hydrogen fluoride, water and other components. The hydrogen fluoride gas in it is very harmful to the crops in the surrounding environment. The treatment of fluorine-containing waste gas is very necessary and urgent. [0003] The traditional wet flue gas dedusting and defluorination dedusting process is generally an external tower type, and the purpose of removing hydrogen fluoride in the flue ...

AI Technical Summary

Problems solved by technology

The deficiencies of commonly used technologies such as cloth bag, cyclone, static electricity, and water film are: high equipment purchase costs; easy blockage of the system; dust removal and dehydrogenation cannot be completed simultaneously; high environmental protection operation costs; poor defluorination effect

[0004] This shows that above-mentioned existing defluorination desulfurization dedusting device and technology obviously still have inconvenience and defect, and urgently need to be further improved

In order to solve the existing problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time. This is obviously a problem that the relevant industry is eager to solve.
