Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a multi-stage waste gas purification treatment device. Background Technology

[0002] Waste gas is toxic and harmful gas emitted by humans during production and daily life, especially from chemical plants, steel plants, pharmaceutical plants, coking plants, and oil refineries. If waste gas is directly discharged into the atmosphere, it will cause environmental pollution. Therefore, waste gas needs to be purified before it is discharged.

[0003] The prior art, with publication number CN218794875U, discloses a multi-stage waste gas purification device, which includes a treatment box. A drain pipe is located at the bottom of one side of the treatment box, and an exhaust pipe is located at the top of one side of the treatment box, directly above the drain pipe. One end of the exhaust pipe is connected to a filter element. A fixing ring is installed inside the treatment box, and a filter plate is located at the top of the fixing ring. A shielding cover is located at the top of the filter plate. The device uses a longitudinal parallel arrangement to purify the waste gas, effectively saving space. Simultaneously, the filter element design effectively adsorbs impurities and odors in the waste gas, improving the cleanliness of the waste gas emissions and thus protecting the environment.

[0004] However, this waste gas purification device does not have the function of cleaning the filter plates during use. After long-term use, some impurities in the waste gas accumulate on the surface of the filter plates, causing blockage of the filter plates, affecting the transport of waste gas, and reducing the waste gas treatment effect. Therefore, a multi-stage purification waste gas purification device is proposed to solve the problems mentioned above. Utility Model Content

It solves the problem that existing waste gas purification devices do not have the function of cleaning the filter plates during use, and after long-term use, some impurities in the waste gas accumulate on the surface of the filter plates, causing filter plate blockage, affecting the transport of waste gas, and reducing the waste gas treatment effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage waste gas purification treatment device, comprising a housing, wherein a filter plate is fixedly installed inside the housing, a demister is fixedly installed on the top of the housing, a spraying mechanism is provided between the filter plate and the demister, and a cleaning mechanism is provided below the filter plate.

[0007] The cleaning mechanism includes a drive motor, a shaft is fixedly mounted on the output shaft of the drive motor, a main gear is fixedly connected to the end of the shaft away from the drive motor, a driven gear meshes with the outer side of the main gear, a connecting shaft is fixedly connected to the upper side of the driven gear, and a brush plate is fixedly connected to the upper end of the connecting shaft. The brush plate is in contact with the lower surface of the filter plate.

[0008] Furthermore, an exhaust pipe is fixedly installed on the top of the demister, and an air inlet pipe is fixedly installed on the side wall of the housing.

[0009] Furthermore, a mounting bracket is fixedly connected to the outer wall of the box, the drive motor is fixedly mounted on the upper side of the mounting bracket, and a drain pipe is also provided on the side wall of the box.

[0010] Furthermore, the shaft extends into the interior of the housing, and an installation plate is fixedly installed inside the housing, with an opening on the inner side of the installation plate.

[0011] Furthermore, a protective cover is fixedly connected to the top of the mounting plate, and both the main gear and the driven gear are located inside the protective cover. Both the main gear and the driven gear are bevel gears, and the shaft and the connecting shaft are connected to the inner wall of the protective cover through bearings.

[0012] Furthermore, the spraying mechanism includes a water pump and a water distribution pipe. The water pump is fixedly installed on the outer wall of the housing, and the water distribution pipe is fixedly installed inside the housing.

[0013] Furthermore, the output end of the water pump is fixedly connected to a connecting pipe, and the end of the connecting pipe away from the water pump is connected to the inlet of the water distribution pipe. The bottom of the water distribution pipe is provided with multiple water outlets, and a nozzle is fixedly installed at the bottom of each water outlet.

[0014] Compared with the prior art, this utility model provides a multi-stage purification device for waste gas treatment, which has the following beneficial effects:

[0015] This multi-stage waste gas purification device works by starting a drive motor to rotate a shaft, which in turn drives a main gear and a driven gear. The driven gear then drives a connecting shaft, which in turn rotates a brush plate. The brush plate cleans impurities from the filter plate surface. The cleaned impurities fall to the bottom of the housing with the spray from the nozzles and are discharged through a drain pipe. This process cleans the filter plates, ensuring the smooth passage of waste gas. It solves the problem of existing waste gas purification devices that lack the function of cleaning filter plates during use. After long-term use, some impurities in the waste gas accumulate on the filter plate surface, causing blockage, affecting the transport of waste gas, and reducing the waste gas treatment effect.
