Description

Technical Field

[0001] The utility model relates to the technical field of waste gas filtering, in particular to a municipal environmental protection waste gas filtering device. Background Art

[0002] Exhaust gas filtration, also known as exhaust gas purification, mainly refers to the work of treating industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial places. Common exhaust gas purifications include factory smoke exhaust gas purification, workshop dust exhaust gas purification, organic waste gas purification, exhaust gas odor purification, acid and alkali waste gas purification, and chemical waste gas purification.

[0003] For example, the Chinese patent with patent number CN209679862U proposes an exhaust gas filter device. The patent sets an exhaust gas filter device at the exhaust port position in the factory. When the air in the factory is discharged to the outside, the harmful gas is processed by the filter device, thereby ensuring the clean index of the exhaust gas. A first filter plate is set in the shell, and the first filter plate is set in a manner perpendicular to the flow direction of the air entering the shell. The first filter plate is provided with a photocatalyst material layer and a combination of an ultraviolet lamp to disinfect the harmful substances in the air, thereby ensuring the quality of the exhaust air. However, in this scheme, since the industrial waste gas contains not only particulate waste gas, but also gaseous waste gas such as sulfur dioxide, when the gaseous waste gas passes through the filter plate and the ultraviolet lamp, the harmful substances inside it may not be easy to be removed, and then the gaseous waste gas will be discharged outdoors, which may cause pollution to the outside air and is not conducive to environmental protection.

[0004] For example, the Chinese patent with patent number CN213853614U proposes an exhaust gas filtering device, which first performs the first step of filtration when passing through the filter element, and then passes through multiple annular filter elements for a second filtration when passing through the air duct. Multiple air ducts can achieve efficient and rapid air intake, improve efficiency, and the exhaust gas is disinfected and sterilized by ultraviolet lamps when passing through the air duct. The long stroke and the short-term blocking of the annular filter element prolong the disinfection time, achieve efficient disinfection and sterilization, and meet the use requirements. However, in this solution, since the industrial waste gas contains not only particulate waste gas, but also gaseous waste gas such as sulfur dioxide, when the gaseous waste gas passes through the filter element and the ultraviolet lamp, the harmful substances inside it may not be easy to be removed, and the gaseous waste gas will be discharged outdoors, which may cause pollution to the outside air and is not conducive to environmental protection.
