DETAILED DESCRIPTION

[0022] The present application is further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0023] A waste gas adsorption recovery and treatment device, such as Figure 1-Figure 2 As shown, it includes: a filter tank 1, an air outlet 17 is provided on the top of the filter tank 1, and the air outlet 17 is connected to the drying tank 2 through a pipe. The end of the drying tank 2 away from the filter tank 1 is connected to the adsorption tank 3 through a pipe. Two air inlets 16 are provided on the top of the filter tank 1, and an air inlet pipe 11 is inserted into the air inlet 16. The air inlet pipe 11 reaches the bottom of the filter tank 1 directly. A separator plate 10 is provided in the filter tank 1. The height of the separator plate 10 is less than the height of the filter tank 1. The separator plate 10 is fixedly connected to the bottom of the filter tank 1, so that there will be space for air circulation above the separator plate 10 and the filter tank 1, which is convenient for the filtered gas to flow into the air outlet 17. The two sides of the separator plate 10 are fixedly connected to the side walls of the filter tank 1. The bottom of the filter tank 1 is provided with two sewage outlets 6, and the two sewage outlets 6 are respectively located on both sides of the separator plate 10.

[0024] like Figure 2 As shown, the two air inlets 16 are axially symmetrical with the liquid separator 10 as the center line, so that the air inlet pipe 11 inserted from the air inlet 16 can be passed into the space on both sides of the liquid separator 10 to react with the absorption liquid 18 therein.

[0025] like Figure 1 As shown, two liquid adding ports 5 are further provided on the side of the filter tank 1 , and the liquid adding ports 5 are axially symmetrical with the liquid separation plate 10 as the center line, so as to facilitate adding the absorption liquid 18 to the space on both sides of the liquid separation plate 10 .

[0026] like Figure 2 As shown, the drying tank 2 is provided with a mesh grid plate 12, which divides the drying tank 2 into a water absorption layer 13 and a gas circulation layer 14. The water absorption layer 13 and the gas circulation layer 14 are alternately arranged. Quicklime is provided in the water absorption layer 13, and quicklime is used to absorb water vapor to improve the gas drying efficiency.

[0027] like Figure 2As shown, the adsorption tank 3 is provided with strip activated carbon 15 , and the strip activated carbon 15 is parallel to the bottom of the adsorption tank 3 , so that the toxic substances in the dried gas can be adsorbed again by the strip activated carbon 15 .

[0028] like Figure 1 As shown, the sides of the drying tank 2 and the adsorption tank 3 are both provided with inspection ports 8 to facilitate replacement of the substances in the drying tank 2 and the adsorption tank 3 .

[0029] like Figure 1 As shown, it also includes a first exhaust fan 7 and a second exhaust fan 9. The first exhaust fan 7 is provided on the pipeline between the filter tank 1 and the adsorption tank 3, and the second exhaust fan 9 is provided on the pipeline between the adsorption tank 3 and the drying tank 2 to improve the efficiency of the exhaust gas flow.

[0030] like Figure 1 As shown, a stop valve 4 is provided on the air inlet 16 , and the opening and closing of the air inlet 16 is controlled by the stop valve 4 .

[0031] like Figure 1 As shown, a stop valve 4 is provided on the sewage outlet 6, and the opening and closing of the sewage outlet 6 is controlled by the stop valve 4.

[0032] In the technical solution of the present application, the exhaust gas is absorbed by the absorption liquid 18 in the filter tank 1, input into the drying tank 2 through the first exhaust fan 7, the water vapor in the exhaust gas is dried, and then input into the adsorption tank 3 through the second exhaust fan 9. The exhaust gas is adsorbed by the activated carbon, and finally transported to the working device for recycling.

[0033] A liquid separator 10 is arranged in the middle of the filter tank 1 to divide the absorption liquid 18 in the filter tank 1 into two parts. Two different air inlet pipes 11 are inserted into the absorption liquid 18 on both sides of the liquid separator 10. The two air inlet pipes 11 can be opened and closed by the stop valves 4 on the two air inlets 16. The stop valves 4 of the two air inlets 16 can be opened at the same time or in turn.

[0034] When the absorption liquid 18 needs to be replaced, the air inlet pipes 11 on both sides of the separator plate 10 are opened in turn by controlling the on and off of the stop valve 4. First, close one stop valve 4, thereby closing the air inlet pipe 11 on one side, and open the drain port 6 on the filter tank 1 corresponding to the closed air inlet pipe 11, so that the absorption liquid 18 that needs to be replaced can be discharged. After draining, add the absorption liquid 18 through the liquid filling port 5. During this process, the air inlet pipe 11 on the other side of the separator plate 10 remains open, so that the entire filter tank 1 will not be closed, affecting the adsorption of the exhaust gas. Therefore, through the technical solution of the present application, the continuous treatment of the exhaust gas in the filter tank 1 can be guaranteed, and the exhaust gas adsorption device will not be stopped due to the replacement of the absorption liquid 18.

[0035] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
