Description

Technical Field

[0001] The utility model relates to an absorption device, in particular to a tail gas absorption device for waste acid treatment, belonging to the technical field of waste acid. Background Art

[0002] Waste acid refers to acidic waste liquid generated during industrial production, which is common in production activities in the chemical, petrochemical, steel and other industries. These waste acids include various acidic substances such as sulfuric acid, hydrochloric acid, nitric acid, etc., which may contain harmful substances such as heavy metals and organic pollutants, posing a potential threat to the environment and human health. Waste acid may be generated in the nitration, esterification, sulfonation, alkylation, catalysis and gas drying of organic matter, or in the production of titanium dioxide, steel pickling and gas drying.

[0003] When treating waste acid, harmful acidic gases and volatile organic compounds will be generated. If these gases are discharged into the atmosphere, they will pollute the environment and cause harm to human health. Therefore, it is necessary to use a tail gas absorption device to absorb and filter the tail gas. The authorization announcement number (CN209630927U) discloses a tail gas absorption device for waste acid treatment. In view of the problem of pollution caused by tail gas emissions in the existing waste acid treatment, the following scheme is proposed, which includes a tail gas absorption tower body, the bottom inner wall of the tail gas absorption tower body is provided with a mounting groove, and a rotating motor is installed in the mounting groove by screws, the top of the rotating motor is connected to an active rod, and the top of the active rod extends to the top inner wall of the tail gas absorption tower body and is rotatably connected thereto, and the two side walls of the tail gas absorption tower body are provided with symmetrically arranged vents, and a filter plate is installed on the side of the vent close to the outer wall of the tail gas absorption tower body;

[0004] Although the above technology can absorb the exhaust gas generated during the waste acid treatment and fully mix it with the dissolving liquid, thereby improving the exhaust gas collection efficiency of the waste acid treatment and effectively reducing environmental pollution, the filter may be difficult to disassemble during use, resulting in a decrease in the filtration efficiency due to impurities and blockages accumulated on the filter, making it impossible to effectively filter harmful gases, thereby increasing environmental pollution and threats to human health. In addition, if the filter is severely clogged and cannot be handled in time, it may cause the pressure of the entire absorption system to increase, increase the equipment failure rate, shorten the service life of the filter, and require more frequent replacement, increasing operating costs.

[0005] Therefore, a tail gas absorption device for waste acid treatment is proposed. Utility Model Content
