Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a chemical waste gas treatment device comprises a fan I1, a pre-cooling pipe 2, a chimney 3, a pre-cooling tower 4, an adsorption tower 5, a desulfurization tower 6, a waste gas processor 7 and a fan II 8.
The fan I1 is an axial flow fan and provides power for waste gas inlet. The fan I1 is communicated with the precooling pipe 2 and blows the waste gas to be treated into the precooling pipe 2. The pre-cooling pipe 2 is spirally wound outside the chimney 3, so that the pre-cooling pipe is installed by taking the chimney as a basic frame, and a larger heat exchange area is realized. The precooling pipe can absorb the cold energy of the treated waste gas in the chimney, and can absorb the cold energy in the air outside the chimney. Therefore, by utilizing the heat exchange and air cooling principles, the waste gas is pre-cooled in advance, and the energy consumption of the subsequent pre-cooling tower is reduced.
The inlet of pre-cooling pipe 2 is located at the upper part of chimney 3, and the outlet of pre-cooling pipe 2 is located at the lower part of chimney 3. The flow direction of the waste gas in the precooling pipe is opposite to that of the waste gas in the chimney, countercurrent heat exchange is formed, and the heat exchange efficiency is improved.
The pre-cooling pipe 2 is communicated with the pre-cooling tower 4, and the waste gas after primary pre-cooling enters the pre-cooling tower for secondary pre-cooling to ensure that the temperature of the waste gas is reduced to a required value. The pre-cooling tower 4 is communicated with a filtering and purifying system, and the filtering and purifying system purifies the waste gas, decomposes and absorbs toxic substances in the waste gas. Filtration purification system and fan II8 intercommunication, fan II8 are centrifugal fan, and fan II8 provides power for the waste gas after handling once more. And the fan II8 is communicated with the chimney 3, the treated waste gas is blown into the chimney, and exchanges heat with the waste gas before treatment, and the cold energy is transferred to the waste gas before treatment and finally is dispersed into the atmosphere.
Specifically, the filtering and purifying system comprises an adsorption tower 5, the precooling tower 4 is communicated with the adsorption tower 5, and an activated carbon adsorbent is arranged in the adsorption tower 5 and used for adsorbing organic waste gas in the waste gas. The adsorption tower 5 is communicated with a desulfurizing tower 6, and the desulfurizing tower carries out desulfurization treatment on the waste gas.
