Description

Technical Field

[0001] The utility model relates to the technical field of sulfur dioxide purification equipment, in particular to sulfur dioxide gas adsorption purification equipment. Background Art

[0002] Sulfur dioxide is one of the main air pollutants. Since coal and oil usually contain sulfur, sulfur dioxide is generated when they are burned. When sulfur dioxide is dissolved in water, sulfurous acid is formed. If sulfurous acid is further oxidized in the presence of PM2.5, sulfuric acid (one of the main components of acid rain) is quickly and efficiently generated. Therefore, sulfur dioxide gas usually needs to be purified before it can be discharged into the air.

[0003] At present, sulfur dioxide gas adsorption purification equipment is usually used to purify sulfur dioxide gas. During the use of sulfur dioxide gas adsorption purification equipment, the sulfur dioxide gas adsorption purification equipment needs to introduce sulfur dioxide gas into the equipment through a fan arranged inside the exhaust pipe, and then pass through adsorption equipment such as activated carbon filter plates to adsorb and purify it. The purified gas is then discharged through the fan, thereby achieving the purification of sulfur dioxide gas;

[0004] Although the existing sulfur dioxide gas adsorption purification equipment can filter sulfur dioxide gas through adsorption equipment such as activated carbon filter plates during use, the adsorption effect of adsorption equipment such as activated carbon filter plates will gradually decrease after long-term use. At this time, it is necessary to replace adsorption equipment such as activated carbon filter plates. However, since adsorption equipment such as activated carbon filter plates are installed and fixed by tightening bolts, the tightening bolts often rust and strip after long-term use, the installation and disassembly of adsorption equipment such as activated carbon filter plates are cumbersome, which reduces the purification efficiency. For this reason, we propose a sulfur dioxide gas adsorption purification equipment. Utility Model Content
