Description

Technical Field

[0001] This utility model relates to the field of air pollution control technology, and in particular to a multi-stage interception, filtration, exhaust gas purification and recovery device. Background Technology

[0002] As people place increasing emphasis on environmental protection, countries are imposing increasingly stringent emission standards on exhaust gases. This has prompted enterprises and research institutions to develop more efficient and multifunctional exhaust gas purification and recovery devices to meet increasingly stringent environmental requirements. Direct incineration produces corrosive gases and easily causes secondary pollution. Direct absorption is difficult to select suitable absorbents and separation is challenging, making it difficult to meet emission standards. Direct condensation has limited applicability. Adsorption is mainly suitable for treating low to medium concentration organic waste gas and has limitations. Exhaust gases have complex compositions, including particulate matter and harmful gases. Traditional single treatment methods are insufficient to effectively address these issues, requiring multi-stage treatment to achieve better purification results. Exhaust gases often contain valuable components. To achieve resource recycling and improve enterprise economic efficiency, it is necessary to develop devices that can purify exhaust gases and recover useful components.

[0003] With increasingly stringent environmental standards, countries have formulated strict laws and regulations on exhaust emissions. Enterprises and vehicles must ensure that their exhaust emissions meet the standards. Purifying and collecting exhaust gases is a necessary measure to meet regulatory requirements. Exhaust gases contain a large number of pollutants, which can lead to environmental problems such as acid rain and photochemical smog. Purification and collection can effectively reduce pollutant emissions and improve air quality. Existing technologies use activated carbon and molecular sieves to adsorb harmful substances in exhaust gases. After the adsorption is saturated, the adsorbent is regenerated by heating to achieve recycling. However, in this filtration and adsorption equipment, the activated carbon is stacked together, which can easily cause blockage, leading to oversaturation in some parts and making it difficult to fully utilize all the activated carbon. Furthermore, the activated carbon is not easy to recycle and replace after long-term use. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-stage interception and filtration exhaust gas purification and recovery device, which aims to improve the problems in the existing technology where filtration and adsorption equipment using a large amount of activated carbon for filtration and adsorption is prone to clogging, leading to oversaturation in some parts, making it difficult to fully utilize all the activated carbon, and the activated carbon is inconvenient to recycle and replace after long-term use.
