Description

Technical Field

[0001] The utility model belongs to the field of chlorine-containing waste gas treatment, and specifically relates to a combined treatment device for chlorine-containing organic waste gas. Background Art

[0002] At present, some methods are adopted to pass chlorine-containing waste gas into alkaline liquid for neutralization treatment. However, although the chlorine is removed by passing into the alkaline gas, alkaline water vapor will adhere to the waste gas, causing secondary pollution, making the exhaust gas acidic, which is not conducive to the cleanliness of the exhaust gas.

[0003] The Chinese patent with the publication number CN209752550U discloses a multi-stage absorption device for chlorine-containing waste gas, including a tank body with an absorption liquid inlet at the top and an absorption liquid overflow outlet at the bottom, a stirring mechanism inside the tank body, an air intake distributor and an exhaust gas discharge outlet at the top, a bubbler immersed in the absorption liquid at the lower end of the air intake branch pipe of the air intake distributor, and a multi-stage absorption structure is arranged in the bubbler. Chlorine-containing waste gas is injected into the tank body through the air intake distributor, and the chlorine-containing waste gas enters the bubbler from the air intake branch pipe. With the help of the multi-stage absorption structure in the bubbler, the chlorine-containing waste gas can be fully contacted with the absorption liquid, and the chlorine in the chlorine-containing waste gas is dissolved in the absorption liquid; the absorption liquid absorbing chlorine is stirred by the stirring mechanism, and the absorption liquid keeps the liquid level in the tank body unchanged through the absorption liquid inlet and the absorption liquid overflow outlet. The absorption efficiency of the utility model reaches more than 90%, which realizes the recovery and reuse of chlorine, reduces the amount of alkali used in the final alkali solution absorption, and saves costs. However, the nozzle of the multi-stage absorption device for chlorine-containing waste gas in the application is directly sprayed into the reaction liquid, which is easy to generate bubbles and cause part of the gas to be discharged from the device without complete reaction, affecting the treatment effect of the waste gas.

[0004] In view of this, the present utility model is proposed. Utility Model Content
