Description

Efficient cooling structure with filtering function Technical Field The utility model relates to the technical field of cooling structures of incineration devices, in particular to a high-efficiency cooling structure with a filtering function. Background The carbon fiber varieties produced in large scale in industrialization are polyacrylonitrile-based carbon fiber, pitch-based carbon fiber and viscose-based carbon fiber. The polyacrylonitrile-based carbon fiber has the advantages of simple production process, good comprehensive performance, rapid development and absolute advantage in carbon fiber production. The VOCs gas generated in the production process of the polyacrylonitrile-based carbon fiber contains Hydrogen Cyanide (HCN) extremely toxic substances, the discharge index of the substances is extremely severe, the discharge is standard, and the VOCs containing hydrogen cyanide usually adopt a sectional type multistage combustion treatment process. The sectional multistage combustion treatment process adopts a direct combustion furnace for zone combustion, oxidation-reduction reaction temperature in the furnace is up to 1200 ℃, and the wall surface of the furnace in a combined form of refractory bricks and ceramic cellucotton with high temperature resistance and good heat insulation effect is still not reduced to the heat insulation standard (less than or equal to 60 ℃) of industrial equipment due to the overhigh reaction temperature, so that a cooling cover is arranged at the periphery of the incineration equipment, and the wall surface of the furnace is further cooled in an air draft mode. However, in the carbon fiber production process, the impurities and defects of the precursor are inevitably transferred to the PAN-based carbon fiber, stress concentration occurs under the action of tension in the pre-oxidation and carbonization processes, and when the bearing capacity of the precursor exceeds that of the precursor, the defect part is broken to generate broken filaments. The broken carbon wires are fine like hairlines and can float in the air, the air inlet of the cooling housing can continuously suck the carbon wires, the carbon wires block the fan, the fan is caused to run out in a fault mode, and then the stable operation of the waste gas treatment equipment is affected. In the prior art, the solution is to separate a reinforced concrete structure factory building for a direct-fired furnace (an incineration device) and isolate the factory building from production equipment so as to avoid the phenomenon of carbon wires in the air, but the manufacturing cost is high, and the air inlet pipeline is also frequently blocked due to overlong waste gas air inlet pipeline. Disclosure of utility model The utility model aims to provide a high-efficiency cooling structure with a filtering function, wherein a gas channel formed by an air inlet, a cooling cavity, an air outlet, an air pipe and a cooling fan can continuously contact low-temperature gas with an incineration device, so that the cooling effect of the incineration device is ensured, and a filtering unit can prevent carbon wires in air from entering the cooling fan to influence the normal operation of the cooling fan, and can rapidly open the filtering unit or disassemble and assemble a filtering layer, thereby being convenient for cleaning and replacement.
