[0002] In the process of semiconductor manufacturing, a series of toxic and harmful gases are often generated, such as ammonia, chlorine, hydrogen fluoride, etc. If these gases are directly discharged without treatment, they will not only cause serious pollution to the environment, but also pose a threat to the health of workers. As an efficient gas purification device, the dry adsorption barrel is widely used in the waste gas treatment of the semiconductor industry. Its working principle depends on the strong adsorption capacity of the adsorbent, which can effectively capture and fix these toxic gas molecules to ensure the cleanliness and safety of the production environment.
