[0025] Please refer to Figs. 1 to 3 The utility model provides a kind of technical scheme: a kind of comprehensive treatment device suitable for dust-containing waste gas, including gas dust separation tank 1, fixedly connected to the inlet valve 2 of the gas dust separation tank 1 inlet and fixedly connected to the exhaust valve 3 of the gas dust separation tank 1 exhaust, the upper surface of gas dust separation tank 1 is equipped with the spray structure for gas dust separation.

[0027] The inlet end of inlet valve 2 is provided with a pretreatment assembly for adsorbing harmful substances in the gas.

[0028] The inner side of gas dust separation tank 1 is provided with an auxiliary assembly for improving the efficiency of gas dust separation.

[0029] It should be noted that the end of water delivery pipe 7 away from water pump 6 penetrates the upper surface of gas dust separation tank 1 and extends to the inner side of gas dust separation tank 1 and is fixedly connected to the water inlet of spray pipe 8, and the end of water delivery pipe 7 away from water pump 6 penetrates gas dust separation tank 1 and is fixedly connected to spray pipe 8, which ensures that the water pumped by water pump 6 can be smoothly delivered to spray pipe 8, providing stable water source for spray structure.

[0030] The spray pipe 8 is fixedly connected between the left and right inner side walls of the gas-dust separation box 1, the bottom of the spray pipe 8 is provided with a plurality of spray water outlets, and each spray water outlet is fixedly connected with an atomizing nozzle 9. This design enables water to be uniformly sprayed in the gas-dust separation box 1, and the water is atomized into fine droplets by the atomizing nozzle 9, increasing the contact area with the dust exhaust gas, thereby improving the gas-dust separation efficiency.

[0031] The pretreatment assembly includes a pretreatment box 10 fixedly connected to the air inlet end of the air inlet valve 2, three activated carbon plates 11 fixedly connected to the inner side of the pretreatment box 10, and an exhaust gas delivery pipe 12 fixedly connected to the air inlet of the pretreatment box 10. The activated carbon plates 11 can adsorb harmful substances in the gas, such as particulate matter and volatile organic compounds, reducing the pollutant content in the exhaust gas entering the gas-dust separation box 1, thereby reducing the subsequent processing burden.

[0032] The right side of the gas-dust separation box 1 is fixedly connected with a support plate 13, and the upper surface of the support plate 13 is in close contact with the bottom of the pretreatment box 10, providing stable support for the pretreatment box 10 and ensuring the smooth progress of the pretreatment process. The exhaust end of the exhaust valve 3 is fixedly connected with a gas discharge pipe 14.

[0033] The auxiliary assembly includes a partition plate 15 fixedly connected to the inner side of the gas-dust separation box 1, a motor 16 fixedly connected to the bottom of the partition plate 15, a transmission rod 17 fixedly connected to the output shaft of the motor 16, a transmission gear 18 fixedly connected to the outer side of the transmission rod 17, a driven gear 19 meshing with the left and right sides of the transmission gear 18, a driven rod 20 fixedly connected to the inner side of the center of the driven gear 19, and a stirring paddle 21 fixedly connected to the outer side of the driven rod 20.

[0035] In addition, the front of the gas-dust separation box 1 is provided with a cleaning door and a motor maintenance door. The design of the cleaning door enables the operator to easily access the inside of the gas-dust separation box 1 for regular cleaning of accumulated dust and dirt, which helps to maintain the cleanliness of the inside of the gas-dust separation box 1. The motor maintenance door allows the operator to easily access the motor components for necessary inspection, maintenance and replacement.

[0036] The working principle of the above embodiment is as follows:

[0037] The waste gas conveying pipe 12 introduces the dust-containing waste gas into the pretreatment box 10, and the box is provided with three activated carbon plates 11. Due to the pore structure and chemical properties of the activated carbon plates 11, the activated carbon plates 11 have strong adsorption capacity for harmful substances such as particulate matter and volatile organic compounds in the waste gas. Through the adsorption of the activated carbon plates 11, the content of pollutants in the waste gas is significantly reduced, thereby reducing the burden of subsequent gas-dust separation.

[0038] The water pump 6 is started, the water pump 6 draws clean water from the water tank 4, and the water is conveyed to the water conveying pipe 7 through the water suction pipe 5, and finally injected into the spray pipe 8. The spray pipe 8 is fixedly installed between the inner walls of the gas-dust separation box 1, and the bottom of the spray pipe 8 is densely covered with atomizing nozzles 9. The atomizing nozzles 9 can finely atomize the water into small water droplets to form a dense water mist covering the inside of the gas-dust separation box 1. When the dust-containing waste gas enters the gas-dust separation box 1 through the air inlet valve 2, it first encounters the water mist. Due to the small size and high specific surface area of the water droplets, they can quickly combine with the dust particles in the waste gas to form heavier particulate matter, thereby preliminarily realizing gas-dust separation.

[0039] In order to improve the separation efficiency, the motor 16 drives the transmission rod 17 to rotate, thereby synchronously rotating the transmission gear 18 and the driven gear 19. The driven gear 19 is connected to the stirring paddle 21 through the driven rod 20, so that the stirring paddle 21 can freely rotate in the gas-dust separation box 1. The rotation of the stirring paddle 21 not only enhances the collision opportunity between the water droplets and the dust particles, but also promotes the uniform distribution of the waste gas, thereby improving the efficiency of the gas-dust separation. At the same time, the water-absorbing sponge 22 on the partition plate 15 can absorb the excess water generated during the separation process.

[0040] The electrical components appearing in the text are electrically connected with the main controller and the power supply. The main controller can be a conventional known device such as a computer, and the existing disclosed power connection technology is not described in detail in the text.
