Abstract
Description
Technical Field
[0001] The utility model relates to the field of titanium dioxide preparation, in particular to a titanium dioxide preparation acidolysis tail gas spray water treatment device. Background Art
[0002] The preparation of titanium dioxide usually involves the process of extracting titanium from titanium ore, in which acidolysis is an important step. Acidolysis tail gas mainly refers to the gas produced during the acidolysis process. These gases may contain ammonia, carbon dioxide, hydrogen sulfide, etc. Acidolysis tail gas cannot be discharged directly and needs to be sprayed through a spray tower. The spray water in the tower is not frequently replaced. After each treatment of the acidolysis tail gas, the spray water will be recycled and reused. However, in order to ensure the spray water's ability to absorb specific gases in the acidolysis tail gas, specific chemicals need to be added to the recycled spray water.
[0003] After searching, Chinese patent announcement number: CN221492042U discloses an automatic dosing system for a tail gas spray tower. In view of the existing practice of adding drugs to the spray tower, manual dosing is usually performed manually. Manual dosing is not only time-consuming and labor-intensive, but also the amount of drugs added is not accurately controlled. As a result, manual calculation is required to obtain the required amount of drugs, which reduces the accuracy of drug amount control. The following scheme is proposed, including a spray tower body, a control box is fixedly installed on the outer wall of the spray tower body, and a liquid alkali concentration detector and a liquid level meter are respectively provided on the top outer wall of the spray tower body. When used, the utility model is conducive to the spray tower body to treat the tail gas to meet emission standards, while achieving the effect of automatic dosing and improving the accuracy of the amount of liquid medicine to be added. There is no need for manual dosing, which is not only time-consuming and labor-intensive, but also the amount of drugs added is not accurately controlled.

If it is directly added to the spray water without mixing, it is easy to cause uneven solution, affecting the treatment effect of the spray water, which is not practical enough. Therefore, a titanium dioxide preparation acidolysis tail gas spray water treatment device is proposed to solve the above problems. Utility Model Content
