Abstract

The invention belongs to the technical field of dust removal after incineration of large-tow carbon fiber waste gas, and particularly relates to a high-temperature silicon-containing dust cleaning device after incineration of carbon fiber waste gas. Wherein the dust removal machine body comprises a settling chamber, an aeration pipe arranged in the settling chamber, a waste discharge fan mounted on the settling chamber and used for exhausting air, and a waste discharge pipeline connected to the exhaust side of the waste discharge fan; the dust removal mechanism is connected to the waste discharge pipeline and comprises an air inlet pipe connected to the waste discharge pipeline. Compared with original manual cleaning, manpower is saved, safety and reliability are achieved, cleaning can be conducted without personnel entering the boiler, hidden dangers are avoided, the personal health of the personnel is guaranteed, cleaning can be conducted after shutdown, the situation that maintenance and cleaning can be conducted after the temperature needs to be reduced to 40 DEG C or below is avoided, cleaning time is saved, and the working efficiency is improved. Therefore, a guarantee is provided for driving in advance, energy waste is reduced, the yield is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of dust removal after the incineration of large tow carbon fiber waste gas, in particular to a high-temperature silicon-containing dust cleaning device after the incineration of carbon fiber waste gas. Background technique [0002] Carbon fiber carbonization is an important process in the production of PAN-based carbon fibers. During the carbonization process, pyrolysis and polycondensation reactions occur, resulting in a large amount of by-product waste gas and tar. These reactions produce gases of suspended particulate matter such as NH3, HCN, SO2, and nitrogen oxides, which are directly discharged and cause air pollution. The exhaust gas needs to be decomposed by a direct-fired incinerator, and the dust generated after combustion settles in the settling chamber of the boiler. , Long-term production, more and more dust, hanging on the wall of the heat exchange tube and the settling chamber, resulting in po...
