Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment devices, and particularly relates to a waste gas treatment device and method for cable production. Background Art

[0002] There are numerous wire and cable products, and some production processes will generate air pollutants during production. For example, the waste gas generated by the up-drawing method for copper rod production, the organic waste gas generated by the extrusion process, and the waste gas generated by the cable coating curing production process; among them, the main pollutants in the waste gas of the cable coating curing production process are cresol, ethylene, etc., which mostly come from the volatilization of solvents or diluents in the drying process.

[0003] An existing waste gas treatment device for cable production (Publication No.: CN219804445U) has at least the following drawbacks: The above patent mixes the waste gas with the treatment liquid in the treatment tank. After the treatment liquid is mixed, the waste gas rises. During the rising process, the treatment liquid enters the spray pipe through the connecting pipe, and the waste gas is further treated by the spray head. The waste gas after spraying rises to the activated carbon filter plate, and the activated carbon filter plate adsorbs the remaining substances in the waste gas; since when using the activated carbon filter plate to adsorb harmful substances in the waste gas, the adsorption capacity of the activated carbon particles will gradually reach the saturation state, at this time, it is necessary to stop the machine to replace the activated carbon filter plate, resulting in the inability to continuously purify the waste gas.
