Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment for chemical equipment, in particular to a waste gas filtering device for chemical equipment. Background Art

[0002] Chemical equipment waste gas refers to the toxic and harmful gases discharged by chemical plants during the chemical production process. These waste gases often contain a variety of pollutants with complex physical and chemical properties and different toxicities, which seriously pollute the environment and affect human health.

[0003] The patent website announcement number CN217746226U discloses an exhaust gas filter device for chemical equipment, which uses a filter tank, a filter screen is provided inside the filter tank, an air inlet hole connected to an air pipe for conveying exhaust gas from the outside is provided at the center of one end face of the filter tank corresponding to the filter screen, and a plurality of baffles are provided at the air inlet hole; one end of each baffle is hinged to the end face of the air inlet hole of the filter tank through a corresponding hinge; each baffle is evenly distributed along the center of the air inlet hole and stacked in sequence; each baffle can be synchronously rotated around the corresponding hinge under the drive of the driving member, thereby changing the size of the opening formed by each baffle and the air inlet hole of the filter tank. The air inlet opening of the utility model can be evenly changed and adapted to the filter tank, and has high filtering efficiency.

[0004] The above-mentioned device only controls the gas volume by synchronously rotating each baffle around the corresponding hinge under the drive of the driving member, thereby changing the opening size formed by each baffle and the air inlet hole of the filter tank to achieve the purpose of purifying and filtering waste. However, after long-term use, a large amount of deposited dust will be generated on the inner wall of the air pipe for external exhaust gas transportation, which will cause the pipe aperture to shrink, thereby affecting the waste filtering and purification effect, so it needs to be improved.

At the same time, the blower 2 inhales air to accelerate the exhaust gas to move inward through the smoke exhaust pipe 31 for purification. At this time, the airflow in the smoke exhaust pipe 31 increases. Due to the action of the bearing 361 and the blade 381, the cleaning rod 38 rotates under the action of the airflow, so that the cleaning brush 382 brushes and cleans the inner wall of the smoke exhaust pipe 31, and removes the deposited dust, thereby ensuring that the aperture of the smoke exhaust pipe 31 remains unchanged, and the purpose of purifying and filtering the exhaust gas is achieved efficiently.
