Description

Technical Field

[0001] The utility model relates to the field of industrial waste gas adsorption and dust removal, in particular to an industrial waste gas adsorption and dust removal device. Background Art

[0002] Industrial waste gas refers to gaseous emissions emitted during the industrial production process, including oxides, particulate matter, volatile organic compounds, ammonia, sulfides, etc. These waste gas emissions may cause harm to the environment and human health, so they need to be treated through appropriate control and treatment methods to reduce the impact on the environment. The waste gas contains a lot of dust, which needs to be treated before purifying the air to ensure the purification effect.

[0003] After searching, the dust removal device of the waste gas pretreatment equipment with announcement number CN214233363U includes an air duct, a primary dust removal mechanism, and a secondary dust removal mechanism. The right side wall of the primary dust removal mechanism is connected to one end of the air duct, and the other end of the air duct is connected to the secondary dust removal mechanism. The present application sets a primary dust removal mechanism and a secondary dust removal mechanism, and performs pre-dust removal by the primary dust removal mechanism and then performs secondary dust removal by the secondary dust removal mechanism, so that the dust in the industrial waste gas can be further adsorbed, which to a certain extent avoids the phenomenon that the dust removal of the existing dust removal mechanism is not thorough enough and improves the dust removal efficiency. The dust in the industrial waste gas can be further adsorbed through the secondary dust removal, which greatly solves the problem that the dust removal of the existing dust removal mechanism is not thorough enough. At the same time, the present application sets an exhaust fan at the lower end of the air outlet, so that the suction force of the exhaust fan can be utilized, which effectively speeds up the working efficiency of the dust removal mechanism and saves time.

[0004] Based on the above patent, the background technology mentioned in it only relies on the cloth bags to adsorb the dust in the industrial waste gas. Due to the small area of ​​the cloth bags, the contact area with the waste gas is small when adsorbing the waste gas. In addition, the cloth bags in the prior art will cause the gaps in the bags to be blocked after long-term use, resulting in low dust removal efficiency during the dust removal process. In this regard, in response to this technical problem, this application proposes an industrial waste gas adsorption dust removal device. Utility Model Content
