Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a waste gas treatment and purification device and method for asphalt production, which solves the problem that the existing purification device proposed in the above-mentioned background technology cannot handle large particles of impurities in the waste gas during use. It is sufficient, and cannot re-use the waste water generated in the spraying process, and the purification effect is not good, it is easy to cause the blockage of the filter screen, and it is not convenient to deal with the generated impurities, which cannot meet people's needs. demand and other issues

The invention discloses a waste gas treatment and purification device and method for asphalt production, relates to the technical field of asphalt production equipment, and in particular, relates to a waste gas treatment and purification device and method for asphalt production. The waste gas treatment and purification device for asphalt production comprises a spray tower and a water pipe; the left side of the spray tower is fixedly connected with a gas inlet, and the interior of the spray tower is fixedly connected with a flow guide cover; and a spray head is in threaded connection with the lower portion of the water pipe, the water pipe is located below the flow guide cover, a bottom plate is fixedly connected to the lower portion of the spray tower, water pumps are arranged on the left side and the right side of the bottom plate, a connecting pipe is movably connected to the upper portion of the spray tower, and a purification tower is arranged on the right side of the connecting pipe. When the waste gas treatment and purification device and method for asphalt production are used, large-particle impurities in waste gas are fully treated, waste water generated in the spraying process can be well reused, meanwhile, the purification effect is good, a filter screen is not prone to being blocked, and the generated impurities can be conveniently treated.
Description
technical field [0001] The invention relates to the technical field of asphalt production equipment, in particular to a waste gas treatment and purification device and method for asphalt production. Background technique [0002] Asphalt is a viscous, black and highly viscous liquid or semi-solid petroleum with a black surface and soluble in carbon disulfide and carbon tetrachloride. Asphalt can be mainly divided into coal tar pitch, petroleum pitch and natural There are three types of asphalt: among them, coal tar pitch is a by-product of coking, petroleum asphalt is the residue after crude oil fractionation, and natural asphalt is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. The main purpose of asphalt is about 70% Asphalt, is used in road construction, asphalt is used as a glue or binder mixed with construction aggregate granules to produce asphalt concrete, other major uses of asphalt are for bitumen waterproofing, includ...
