[0043] When the first organic matter sensor 401 detects that there is still organic matter in the exhaust gas, the switch is closed and the detection lamp is turned on. However, the first placement frame 31 above the first organic matter sensor 401 continues to adsorb the remaining organic matter. When the activated carbon in the first placement frame 31 is activated, the second placement frame 311 is moved by moving the control rod 333, and the activated carbon in the second placement frame 311 is replaced. The replaced activated carbon can be restored to its activity by chemical or physical means for recycling next time.

[0044] When the second placement frame 311 and the first placement frame 31 move in the inner side of the outer fixed frame 101, the moving groove 204 opened on the side of the built-in frame 201 provides space for them. However, the other side of the built-in frame 201 is not provided with a moving groove 204. To prevent the exhaust gas from entering the inner side of the built-in frame 201 and being discharged into the outside air, when the second placement frame 311 moves to the inner side of the built-in frame 201, the other side of the second placement frame 311 is still blocked at the moving groove 204 to prevent the exhaust gas from spreading. The cleaning rod 205 placed behind the moving groove 204 wipes the water mist attached to the bottom of the second placement frame 311 when it moves.

[0045] Referring to Figures 5 to 8 , the side of the second placement frame 311 is fixedly connected with a moving ring 324, the inner side of the moving ring 324 is connected with a moving rod 32, the side of the moving rod 32 is connected with a T-shaped fixed shaft 321, the side of the T-shaped fixed shaft 321 is fixedly connected with the side of the first placement frame 31, the side of the moving rod 32 is provided with a spiral groove 325, the side of the spiral groove 325 is threadedly connected with the inner side of the moving ring 324, and the bottom end of the spiral groove 325 is fixedly connected with a supporting pad 326.

[0046] The top end of the T-shaped fixed shaft 321 is fixedly connected with a control plate 322, the top end of the control plate 322 is fixedly connected with a second supporting plate 327, the inner side of the second supporting plate 327 is connected with a control rod 333, the top end of the moving rod 32 is connected with a supporting pad plate 326, the top end of the supporting pad plate 326 is fixedly connected with a first supporting plate 323, the side surface of the first supporting plate 323 is connected with the side surface of the control rod 333, and the side surface of the control plate 322 is connected with the inner side of the sliding groove 106.

[0047] The side surface of the control rod 333 is connected with a guide frame 33, the side surface of the guide frame 33 is provided with an annular sliding groove 331, the inner side of the annular sliding groove 331 is connected with the side surface of the control rod 333, the top end of the annular sliding groove 331 is provided with a vertical sliding groove 332, and the bottom end of the guide frame 33 is fixedly connected with a bearing rod 334.

[0048] The monitoring mechanism 4 comprises a first organic matter sensor 401 and a second organic matter sensor 402, the side surface of the first organic matter sensor 401 is fixedly connected with a supporting rod 403, the side surface of the supporting rod 403 is fixedly connected with the inner side of the outer fixed frame 101, and the fixing of the second organic matter sensor 402 is the same as that of the first organic matter sensor 401.

[0049] When the second placing frame 311 moves to the inner side of the built-in frame 201 to replace the activated carbon, the tail gas is subjected to organic matter adsorption treatment through the first placing frame 31, and the movement of the second placing frame 311 and the first placing frame 31 is realized through the control rod 333, when the control rod 333 moves up and down the moving rod 32, the second supporting plate 327 at the top end of the control plate 322 is equivalent to the fulcrum of a lever, so that the control plate 322 does not move up and down with the moving rod 32, and the supporting pad plate 326 at the top end of the moving rod 32 is sleeved, so that the moving rod 32 is not rotated when the control plate 322 rotates, and the movement of the second placing frame 311 and the first placing frame 31 does not interfere with each other.

[0050] The working principle of the application is as follows: when the tail gas to be treated is injected from the air inlet pipe 105 to the inner side of the outer fixed frame 101, the built-in frame 201 is arranged at the inner side of the outer fixed frame 101, so that the inner side of the built-in frame 201 is divided into a hydrolysis bin 107 and an inner side region of the built-in frame 201, a water solution is placed in the hydrolysis bin 107, and the impurities dissolved in water in the tail gas are dissolved, after the tail gas comes out of the hydrolysis bin 107 and reaches the second placing frame 311, the activated carbon placed in the second placing frame 311 can adsorb and treat the organic matter in the tail gas, and after being adsorbed by the second placing frame 311 and the first placing frame 31, the tail gas is discharged to a detection gas device through the air outlet pipe 103 to detect the discharge standard.

[0051] The first organic matter sensor 401 is arranged between the second placing frame 311 and the first placing frame 31, to detect whether the adsorption capacity of the activated carbon inside the second placing frame 311 reaches saturation, when the first organic matter sensor 401 detects organic matter above the second placing frame 311, a closed switch will light up the alarm lamp, after the light is on, the moving rod 32 can be controlled to move the second placing frame 311, through the up-down movement of the moving rod 32, the screw groove 325 on the side of the moving rod 32 is in threaded connection with the moving ring 324, so that the movement of the moving rod 32 drives the rotation of the moving ring 324, the second placing frame 311 fixed on the side of the moving ring 324 can be moved to the inside of the built-in frame 201, when the second placing frame 311 is fixed, the cabinet door 108 on the side of the feeding opening 104 is opened, the activated carbon inside the second placing frame 311 is replaced, then the outer fixed frame 101 is sealed again, the moving rod 32 is moved back to the original position, and the second placing frame 311 is reset, when the second placing frame 311 works again, the first organic matter sensor 401 detects no organic matter, and the power supply is automatically disconnected to turn off the alarm lamp;

[0052] When the built-in activated carbon in the second placing frame 311 is replaced, the tail gas floated subsequently is adsorbed by the first placing frame 31, when the first organic matter sensor 401 and the second organic matter sensor 402 detect organic matter at the same time and the alarm lamp is turned on, the air inlet function of the air inlet pipe 105 is stopped, the activated carbon inside the first placing frame 31 and the second placing frame 311 needs to be replaced, the first placing frame 31 and the second placing frame 311 are moved by controlling the control rod 333, when the control rod 333 slides in the annular sliding groove 331, the T-shaped fixed shaft 321 fixed at the bottom end of the control plate 322 rotates on the side of the moving rod 32, the support pad plate 326 fixed at the bottom end of the first support plate 323 is in sleeve connection with the moving rod 32, so that the rotation of the first support plate 323 does not drive the rotation of the moving rod 32, and the movement of the first placing frame 31 and the second placing frame 311 does not affect each other.

[0053] Therefore, when the control rod 333 slides in the annular sliding groove 331, the first placing frame 31 rotates inside the outer fixed frame 101, the fixed teeth 313 on the side of the first placing frame 31 meshes with the tooth ring 203 from the side, the first placing frame 31 is moved to the inside of the built-in frame 201 for replacement of the activated carbon, and the control rod 333 slides up and down in the vertical sliding groove 332 to drive the moving rod 32 to move up and down, so that the second placing frame 311 rotates to the inside of the built-in frame 201, the moving groove 204 with the height of the first placing frame 31 is opened on the side of the built-in frame 201, so that the second placing frame 311 can also be a sealing door at the built-in frame 201.

[0054] When the second placing frame 311 and the first placing frame 31 move to the inner side of the built-in frame 201, a cleaning rod 205 is arranged at the side of the moving groove 204, and the impurities adsorbed at the bottom end of the second placing frame 311 are wiped clean by the second placing frame 311 rolling at the side of the cleaning rod 205, so as to prevent the secondary pollution of the impurities to the tail gas treatment, and the bottom end of the first placing frame 31 is also provided with the article for cleaning when the first placing frame 31 moves in and out of the moving groove 204.

[0055] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
