Smoke recycling and purifying device

Abstract

The invention discloses a smoke recycling and purifying device, and belongs to the technical field of smoke treatment, the smoke recycling and purifying device comprises a main smoke pipe, one side of the main smoke pipe is connected with a smoke inlet pipe, one end of the main smoke pipe is internally provided with a dust screening mechanism, the dust screening mechanism comprises a screen and a fixing frame, the screen is fixedly installed on the inner side of the fixing frame, and the screen is fixedly installed on the inner side of the fixing frame. The four corners of the top end of the fixing frame are fixedly connected with sliding rods, the top ends of the sliding rods are fixedly connected with limiting blocks, the outer sides of the sliding rods are sleeved with springs, the inner wall of the main smoke pipe is fixedly connected with a fixing block, the fixing block is arranged at the top end of the fixing frame, and a sliding hole is formed in the fixing block; by arranging the purification assembly, the activated carbon plate rotates integrally, the activated carbon plate can make full contact with smoke and conduct effective adsorption and purification when rotating, the plate-shaped activated carbon plate circularly rotates, the smoke can be conducted downwards, the smoke purification effect can be improved, the smoke discharging speed can be increased, and the smoke recycling and purification effect can be improved.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a smoke recovery and purification device. Background technique [0002] In the process of cutting, forging, grinding, shaping and welding of industrial production equipment, metal parts are accompanied by the emission of some toxic gases and smoke, which will often cause harm to the on-site production personnel. This smoke needs to be cleaned after purification recycle and re-use. [0003] The smoke is generally stored in the smoke storage tank through the smoke pipe. In the prior art, the smoke is generally purified by adding fixed activated carbon in the smoke pipe to absorb the poisonous particles in the smoke. However, adding multiple layers of activated carbon will reduce The smoke exhaust efficiency of the smoke pipe, the purification and adsorption effect of single-layer activated carbon is poor. Therefore, the fixed addition of activated carbon in the smoke pi...

[0003] The smoke is generally stored in the smoke storage tank through the smoke pipe. In the prior art, the smoke is generally purified by adding fixed activated carbon in the smoke pipe to absorb the poisonous particles in the smoke. However, adding multiple layers of activated carbon will reduce The smoke exhaust efficiency of the smoke pipe, the purification and adsorption effect of single-layer activated carbon is poor, therefore, the fixed addition of activated carbon in the smoke pipe has certain limitations for smoke purification
