Kiln gas semi-dry process defluorination desulphurization dedusting equipment

Abstract

The invention provides kiln gas semi-dry process defluorination desulphurization dedusting equipment. The kiln gas semi-dry process defluorination desulphurization dedusting equipment comprises a technology water tank, a technology water pump, a first stage technology water flowmeter, a defluorination tower Venturi segment structure, a leakproof cap, a waste dust packaged conveying vehicle structure, a defluorination tower structure, a second stage technology water flowmeter, a defluorination tower outlet flue, a cyclone separator, a cyclone separator outlet flue, a discharge pipe, a first stage smoke discharge pipe, a defluorination tower material return inclined groove, a lime powder cabin structure, a first stage connecting pipe, a hand-operated valve, a desulphurization outlet flue, asmoke outlet pipe, a desulphurization Venturi segment, a desulphurization lower layer nozzle, a desulphurization upper layer nozzle, a desulphurization tower, a flue gas induced draught fan, a cloth bag dedusting cylinder structure, a desulphurization material return inclined groove, and a second stage smoke discharge pipe. According to the kiln gas semi-dry process defluorination desulphurizationdedusting equipment, the defluorination tower and the desulphurization tower are adopted, it is beneficial for defluorination and then desulphurization, interaction of defluorination and desulphurization is avoided, defluorination and desulphurization effect is improved; the mechanical valve, a flue gas inlet pipe, and a filter screen are adopted, so that it is beneficial for control of smoke introduction speed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection dust removal equipment, and in particular relates to a kiln flue gas semi-dry defluorination, desulfurization and dust removal equipment. Background technique [0002] The existing coal-fired flue gas purification is mainly desulfurization. The desulfurization device generally includes a reactor nested in the shell. The reactor is equipped with an absorption liquid atomization spray device. The flue gas enters from the upper end of the reactor and is mixed with the fog. After the absorbed liquid (generally ammonia water) is reacted and absorbed, it enters the interlayer between the reactor and the shell through the dehydration demister at the lower end of the reactor, and then is output from the flue gas outlet provided on the shell. On the one hand, due to the short reaction process, the existing desulfurization devices cannot meet the treatment of a large amount of flue gas cont...
