Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, specifically a high-efficiency dust removal and energy-saving waste gas treatment device. Background Technology

[0002] Waste gas treatment devices are facilities used to purify harmful waste gases emitted from industries such as manufacturing and transportation. Their primary purpose is to reduce environmental pollution and protect human health and ecological balance. The working principles of waste gas treatment devices mainly include physical, chemical, and biological methods. Physical methods remove particulate matter and harmful gases from waste gases through adsorption and filtration; chemical methods utilize chemical reactions to convert harmful substances into harmless ones; and biological methods use microorganisms to degrade pollutants in waste gases. Waste gas treatment devices are characterized by high purification capacity, reliable operation, and low carbon footprint, and are widely used in industries such as chemical, metallurgical, power, and printing. With technological advancements, future waste gas treatment devices will become more intelligent and efficient, making a greater contribution to improving the ecological environment.

[0003] An energy-saving waste gas treatment device for high-efficiency dust removal, as disclosed in announcement number CN108119906A, comprises a housing, a heat recovery device, and a cyclone dust collector. An inlet pipe is located on the left side of the housing, extending into the housing and tangentially connected to the cyclone dust collector. A heat recovery device is located on the right side of the housing within a spiral settling cylinder. This invention achieves energy savings by efficiently recovering heat from boiler waste gas through the heat recovery device. The cyclone dust collector and settling cylinder efficiently settle dust in the waste gas, facilitating subsequent processing by a bag filter. The multi-stage dust collection system improves the effectiveness and efficiency of waste gas dust removal. Furthermore, the inclusion of an adsorption box and staggered baffles within the adsorption box increases the contact time between the waste gas and the liquid adsorption medium, enhancing the adsorption effect.

[0004] The aforementioned devices have low dust removal efficiency and are not suitable for long-term dust removal; therefore, we propose an energy-saving waste gas treatment device with high efficiency dust removal to solve the problems mentioned above. Utility Model Content
