Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas treatment, in particular to a purification device for industrial waste gas which is easy to clean. Background Art

[0002] Waste 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 sites. Common waste gas purifications include factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc. Waste gas emitted by industrial production often has harmful effects on the environment and human health. Purification measures should be taken before it is discharged into the atmosphere to make it meet the requirements of waste gas emission standards. This process is called waste gas purification. Commonly used waste gas purification methods are: absorption method, adsorption method, condensation method and combustion method. Waste gas purification equipment is widely used in industries with toxic and harmful gases such as chemical plants and paint factories. Generally speaking, a complete waste gas purification system is composed of devices for capturing polluted gases and treating waste gases. Among them, the gas collecting hood developed by the adsorption method in the prior art has the widest application range. Although the activated carbon plate inside the gas collecting hood of the adsorption collection is replaceable, after a long period of filtration, the filtered dirt will still stick to the inner wall of the box, which will lead to a decrease in filtration efficiency and a deterioration in filtration effect over time. Therefore, the utility model proposes a purification device for industrial waste gas that is easy to clean.

[0003] In the prior art, a Chinese patent document with publication number CN216395656U and publication date April 29, 2022 is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A purification device for industrial waste gas that is easy to clean, belonging to the field of waste gas purification, a purification device for industrial waste gas that is easy to clean, comprising a purification chassis, gas inlets and outlets are opened on both sides of the purification chassis, a drive chamber is installed on the top of the purification chassis, and a cover plate is rotatably installed on the top of the drive chamber, the purification chassis comprises a main side panel and a rotating side panel, the main side panel is arranged in an "L" shape, and the bottom side edge of the rotating side panel is rotatably connected to the side edge of the main side panel, fixed steel frames A are installed at both ends of the interior of the purification chassis, and multiple fixed steel frames B are installed between the two fixed steel frames A and located inside the purification chassis, and the fixed steel frame B is arranged in a "U" shape, which can facilitate the cleaning of the interior of the purification chassis and wipe off the dirt stuck on the inner wall of the chassis.

[0004] In order to solve the problem that the filtered dirt will still stick to the inner wall of the box after a long period of filtration inside the adsorption-type collection hood, the existing technology is to connect the bottom side of the rotating side panel with the side of the "L" shape and the main body side panel, and open the rotating side panel to facilitate cleaning of the inside of the purification case. The motor is arranged on the top of the purification case. When the motor drives the wiping plate to rotate, the top wall of the purification case can be cleaned. A wiping brush is installed on the top of the wiping plate to wipe off the dirt stuck to the inner wall of the box. However, there may be a situation where the purification case needs to reserve space for the motor and the scraper plate on the top, which leads to the problem that the activated carbon cannot be installed on the top, and the industrial waste gas passing through the top cannot be adsorbed, resulting in incomplete treatment.
