[0002] In the production process of metal cleaning agents, since a lot of chemical raw materials are needed in the preparation process, a lot of acidic, alkaline and neutral mists are generated during production. If these mists are not treated and discharged into the air, they will cause a great degree of pollution and are very harmful.

[0003] After searching, a Chinese patent discloses a waste gas treatment device for a metal cleaning agent production line (authorization announcement number CN206688490U), including a production tank, an acid mist treatment tank is provided on the right side of the production tank, an alkaline solution is provided in the acid mist treatment tank, an alkali mist treatment tank is provided on the right side of the acid mist treatment tank, an acid solution is provided in the alkali mist treatment tank, a first pipe is provided in the acid mist treatment tank, a second pipe is provided in the alkali mist treatment tank, and both the first pipe and the second pipe are connected to the production tank through a mist outlet pipe; a purification tank is provided on the right side of the alkali mist treatment tank, water is provided in the purification tank, an air inlet pipe is provided in the purification tank, and the air inlet pipe is connected to the top of the acid mist treatment tank and the alkali mist treatment tank through a third pipe and a fourth pipe, respectively. Although the patented technology can neutralize the acid gas or alkalinity separately to ensure that the generated waste gas is effectively treated, it is then discharged into the purification tank, and the waste gas is treated to make the discharged waste gas non-toxic and harmless.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when the above metal cleaning agent waste gas treatment device is used, a large number of bubbles will be generated when the gas is passed into the water, resulting in incomplete treatment of the waste gas. In addition, a fixed adsorption layer is provided in the above device. After long-term use, more impurities are attached to the filter screen. Excessive accumulation of impurities on the filter screen can easily affect the circulation speed of the waste gas, thereby reducing the purification efficiency of the waste gas.

Thus, the exhaust gas impurities adhering to the inner wall of the treatment tank 1 can be cleaned by the scraping plate 8 to improve the treatment effect of the exhaust gas. When the activated carbon adsorption plate 18 needs to be replaced, the bolts can be loosened, separating the tank cover 2 from the treatment tank 1, and rotating the activated carbon adsorption plate 18 to the left, so that the clamping blocks 19 on both sides of the activated carbon adsorption plate 18 can be disengaged from the limit of the clamping grooves 21, and then the activated carbon adsorption plate 18 can be taken out of the treatment tank 1 for cleaning, and thus the purification effect of the activated carbon adsorption plate 18 can be restored.
