Acid gas discharging device for papermaking workshop

Abstract

The invention discloses an acid gas discharging device for a papermaking workshop. The device comprises an alkaline liquor box and a purification box, the upper end of the alkaline liquor box and theupper end of the purification box are both provided with an opening, the purification box is fixedly connected to the side wall of the alkaline liquor box through a supporting plate, and a first coverbody and a second cover body sleeve the openings in the upper ends of the alkaline liquor box and the purification box; a gas inlet mechanism is fixedly connected to the side, away from the purification box, of the alkaline liquor box, an L-shaped breather pipe is arranged at the inner bottom of the alkaline liquor box, and the upper end of the L-shaped breather pipe penetrates through the alkaline liquor box and is fixedly connected with the gas inlet mechanism; a drainage pipe is arranged at the inner bottom of the alkaline liquor box , an alkaline liquor spraying device is arranged insidethe alkaline liquor box, and the alkaline liquor box is communicated with the interior of the purification box through an exhaust mechanism. The acid gas discharging device is compact in structure andconvenient to operate, acid substances in waste gas can be sufficiently neutralized, the neutralized waste gas is then filtered and adsorbed, the quality of exhaust gas is improved, and the environment is prevented from being polluted.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an acid gas discharge device used in a papermaking workshop. Background technique [0002] A large amount of waste gas will be generated in the production process of the paper making workshop, and there will be a large amount of sour and odorous substances in the waste gas. If the gas generated in the paper making workshop is not treated and discharged directly into the atmosphere, it will not only endanger human health, but also seriously pollute the atmospheric environment. . [0003] At present, although there is equipment for purifying the waste gas discharged from the papermaking workshop in the prior art, it often only treats some acidic gases in the waste gas. Generally, the waste gas is passed into lye for neutralization treatment, but the effect of acid-base mixing degree Poor, unable to remove the acidic substances in the exhaust gas to the maximum extent, ...

Problems solved by technology

[0002] A large amount of waste gas will be generated in the production process of the paper making workshop, and there will be a large amount of sour and odorous substances in the waste gas. If the gas generated in the paper making workshop is not treated and discharged directly into the atmosphere, it will not only endanger human health, but also seriously pollute the atmospheric environment.

[0003] At present, although there is equipment for purifying the waste gas discharged from the papermaking workshop in the prior art, it often only treats some acidic gases in the waste gas. Generally, the waste gas is passed into lye for neutralization treatment, but the effect of acid-base mixing degree Poor, unable to remove the acidic substances in the exhaust gas to the maximum extent, and there are still harmful substances in the discharged gas, which cannot be completely purified
