[0033] In this embodiment, the steam treatment mechanism includes a steam pipe 7, a connecting ring 8 and a connector 9. A positioning rod 10 is fixedly connected to the top and bottom of the connecting ring 8. The positioning rod 10 is inserted into the positioning hole 11 of the shell 3, and then the closing plate 20 is installed on the first closing tube 15, so that the driving motor 19 is connected to the rotating column 14 through an electromagnetic coupling. The connection method can adopt the existing one, or some cylinders are fixed on the electromagnetic coupling, and a cylindrical groove is set on the top of the rotating column 14, and the cylinder is inserted into the cylindrical groove. When the driving motor 19 rotates, the rotating column 14 can be driven to rotate through the electromagnetic coupling.

[0034] Specifically, the activated carbon placement rack 4 includes a containing portion 401 and a closed mesh cover portion 402, the containing portion 401 is connected to the rotating mechanism, the closed mesh cover portion 402 is installed on the top of the containing portion 401, and an array of sewage outlets 5 are opened on the outer wall of the containing portion 401; the containing portion 401 is connected to the inner wall of the shell 3 through a connecting bearing, and the bottom of the containing portion 401 is inclined.

[0035] Specifically, an opening is provided at the bottom of the containing portion 401, and a connecting mesh tube 12 with a closed top is fixedly connected to a position corresponding to the opening inside the containing portion 401.

[0036] Specifically, a receiving ring 13 is fixedly connected to the inside of the shell 3, and the surface of the receiving ring 13 is movably connected to the bottom of the outer wall of the containing part 401. The sewage outlet 5 is located between the receiving ring 13 and the connecting bearing, and the connecting bearing is a waterproof bearing.

[0037] In this embodiment, during the desorption stage, the high-temperature and high-pressure steam is flushed into the shell 3 through the bottom steam treatment mechanism, the steam treatment mechanism in the middle position does not move, and the top steam treatment mechanism absorbs the high-temperature and high-pressure steam to achieve circulation. After a period of treatment, the impurities treated by the high-temperature and high-pressure steam will be separated from the activated carbon and will flow along the bottom of the activated carbon placement rack 4, flow out through the sewage outlet 5, flow into the receiving ring 13, the gap between the connecting bearing and the shell 3, and then flow out through the one-way valve. In order to better flow the retained liquid out of the activated carbon placement rack 4, the drive motor 19 can be started, and the upper rotating column 14 is elastically connected to the lower rotating column 14. In addition, the top steam treatment mechanism is not moved, and the middle steam treatment mechanism moves and draws steam outward, so that the high-temperature and high-pressure steam does not pass through the upper activated carbon, and continues to desorb the lower activated carbon. After that, all steam treatment mechanisms are closed, and the lower activated carbon is subjected to water removal treatment. At the same time, better sewage discharge and desorption can be performed under the action of vibration.

[0038] Specifically, the rotating mechanism includes a rotating column 14, the surface of which is respectively connected to a first closed tube 15 and a second closed tube 16 through two fixed bearings, the activated carbon placement rack 4 is fixedly connected to the rotating column 14, and the first closed tube 15 and the second closed tube 16 are movably connected to the activated carbon placement rack 4; a plug-in rod 17 is fixedly connected to the bottom of the second closed tube 16, and a plug-in groove 18 is provided on the top of the first closed tube 15, and the plug-in rod 17 on the second closed tube 16 located above is movably connected to the plug-in groove 18 of the first closed tube 15 located below; the rotating mechanism also includes a driving motor 19, the driving motor 19 is fixedly connected to the surface of the closing plate 20, the closing plate 20 is plugged into the plug-in groove 18 of the first closed tube 15 through the plug-in rod, the output shaft of the driving motor 19 is connected to the rotating column 14 through an electromagnetic coupling, the surface of the closing plate 20 is fixedly connected to a fixed rod 21, and the fixed rod 21 is clamped with the exhaust hood 1; the rotating column 14 located above is connected to the rotating column 14 located below through a connecting structure.

[0039] Specifically, the connection structure includes a gear connection member connected to the bottom of the rotating column 14, and the top array of the rotating column 14 located below is connected with a plurality of first tooth blocks 22; the gear connection member includes a connecting plate 23 and a second tooth block 24, and the first tooth block 22 is meshed with the second tooth block 24.

[0040] Specifically, the gear connection is movably connected to the rotating column 14, an anti-rotation groove 25 is provided at the bottom of the rotating column 14, the inner side wall of the anti-rotation groove 25 is movably connected to the anti-rotation rod 26, and the end of the anti-rotation rod 26 is fixedly connected to the top of the connecting plate 23; the connecting plate 23 is elastically connected to the rotating column 14.

[0041] Specifically, a spring 27 is fixedly connected to the surface of the connecting plate 23, one end of the spring 27 is fixedly connected to a movable ring 28, the movable ring 28 is movably sleeved on the surface of the rotating column 14, and an electric push rod 29 is fixedly connected to the top of the movable ring 28, and the electric push rod 29 is fixedly connected to the rotating column 14.

[0042] Specifically, a support column 30 is fixedly connected inside the air intake cover 2, and a third tooth block 31 is arranged on the top array of the support column 30. The third tooth block 31 is meshed with the second tooth block 24 on the bottommost gear member.

[0043] In this embodiment, when the activated carbon rack 4 is vibrated, the activated carbon inside it will shake, so that the activated carbons are closer to each other and can fully contact with the organic waste gas. Of course, the main adsorption process still occurs in the activated carbon rack 4 at the bottom. At this time, the electric push rod 29 on the upper rotating column 14 can be started to move the movable ring 28 on it downward, squeeze the spring 27, and then compress the spring 27 to prevent deformation, so that the first tooth block 22 and the second tooth block 24 cannot be relatively displaced. Afterwards, under the action of the drive motor 19, the lower rotating column 14 can be rotated, and the second tooth block 24 and the third tooth block 31 on the lower rotating column 14 can collide with each other, so that the lower activated carbon rack 4 can be vibrated, which can increase the density of the activated carbon, and at the same time reduce the impact of the airflow of the organic waste gas on the activated carbon, so that the activated carbon is loose, which is conducive to adsorption.

[0044] When in use, a proper amount of activated carbon can be placed inside the containing part 401 first, and then the closed mesh cover part 402 can be fixed to the top of the containing part 401 by screws or other existing fastening structures. The closed mesh cover part 402 will be sleeved on the surface of the connecting mesh pipe 12, and a mesh port is provided on the surface of the connecting mesh pipe 12. One of the shells 3 is selected as the topmost structure, and a steam treatment mechanism is placed on the top of this shell 3.

[0045] The steam treatment mechanism includes a steam pipe 7, a connecting ring 8 and a connector 9. A positioning rod 10 is fixedly connected to the top and bottom of the connecting ring 8. The positioning rod 10 is inserted into the positioning hole 11 of the shell 3, and then the closing plate 20 is installed on the first closing tube 15, so that the driving motor 19 is connected to the rotating column 14 through an electromagnetic coupling. The connection method can adopt the existing one, or some cylinders are fixed on the electromagnetic coupling, and a cylindrical groove is set on the top of the rotating column 14, and the cylinder is inserted into the cylindrical groove. When the driving motor 19 rotates, the rotating column 14 can be driven to rotate through the electromagnetic coupling.

[0046] A fixing rod 21 is fixed on the closing plate 20. When the exhaust hood 1 is installed, the fixing rod 21 is made to correspond with the reserved position on the exhaust hood 1, and the positioning hole 11 on the exhaust hood 1 is made to correspond with the positioning rod 10, so as to realize the connection between the exhaust hood 1 and the connecting ring 8 and the upper shell 3. Then, a second steam processing mechanism is installed at the bottom of the upper shell 3, and a second shell 3 is installed below the second steam processing mechanism. When installing the second shell 3, the two rotating mechanisms need to be docked.

[0047] The rotating mechanism includes a rotating column 14, and the surface of the rotating column 14 is respectively connected to a first closed tube 15 and a second closed tube 16 through two fixed bearings, wherein the first closed tube 15 is located above the second closed tube 16, and the top of the first closed tube 15 has a plug-in groove 18, and the top of the second closed tube 16 has a plug-in rod 17. During installation, the plug-in rod 17 is inserted into the plug-in groove 18 to connect the upper second closed tube 16 with the lower first closed tube 15. At the same time, the second tooth block 24 of the toothed member of the upper rotating column 14 will be docked with the first tooth block 22 on the lower rotating column 14 to facilitate transmission.

[0048] Then, the third steam treatment mechanism is installed at the bottom of the lower shell 3, and finally the air intake cover 2 is installed at the bottom of the third steam treatment mechanism, so that the third gear block 31 on the air intake cover 2 is connected with the second gear block 24 of the gear connection member on the lower rotating column 14.

[0049] All the plug-in methods in this embodiment can be plugged in by interference fit to enhance the stability of the connection.

[0050] After the installation is completed, the organic waste gas to be treated is fed into the bottom of the air inlet hood 2, and an exhaust device is set on the top of the exhaust hood 1 to realize the movement of the organic waste gas from bottom to top. Since the organic waste gas can only pass through the connecting network pipe 12, the guidance of the organic waste gas can be realized, so that the organic waste gas enters the connecting network pipe 12 and then begins to diffuse to the outside, that is, the organic waste gas can achieve efficient contact with the activated carbon, instead of the existing gradual contact from bottom to top, which leads to excessive adsorption pressure of the activated carbon at the bottom, and easily causes the activated carbon at the bottom to lose its adsorption capacity quickly. After multiple adsorption and desorption, the service life of the activated carbon at the bottom will be greatly reduced.

[0051] After being treated with activated carbon, it is discharged through the closed mesh cover 402 for secondary activated carbon adsorption. The number of shells can be increased or decreased as needed. During the adsorption process, the drive motor can be started. Under the action of the fixing rod 21 and the exhaust hood 1, the closing plate 20 fixes the top first closing tube 15. The drive motor 19 can make the top rotating column 14 immobile through the electromagnetic coupling. The top rotating column 14 drives the upper activated carbon placement rack 4 to rotate. The rotating column 14 can drive the gear connection to rotate through the anti-rotation groove 25 and the anti-rotation rod 26, so that the lower rotating column 14 can be rotated through the first tooth block 22 and the second tooth block 24. Of course, this is the case when the anti-rotation rod 26 cannot move up and down relative to the anti-rotation groove 25. If the anti-rotation rod 26 can move up and down relative to the anti-rotation groove 25, under the action of the spring 27, the upper rotating column 14 can rotate alone, while the lower rotating column 14 does not rotate. It should be noted that in this case, due to the action of the spring 27, a relative collision will occur between the first tooth block 22 and the second tooth block 24, so that the vibration generated by the collision will be transmitted to the rotating column 14 through the anti-rotation rod 26, and then transmitted to the activated carbon placement rack 4.

[0052] When the activated carbon rack 4 is vibrated, the activated carbon inside it will shake, so that the activated carbons are closer to each other and can fully contact with the organic waste gas. Of course, the main adsorption process still occurs in the activated carbon rack 4 at the bottom. At this time, the electric push rod 29 on the upper rotating column 14 can be started to move the movable ring 28 on it downward, squeeze the spring 27, and then compress the spring 27 to prevent deformation, so that the first tooth block 22 and the second tooth block 24 cannot be relatively displaced. Afterwards, under the action of the drive motor 19, the lower rotating column 14 can be rotated, and the second tooth block 24 and the third tooth block 31 on the lower rotating column 14 can collide with each other, so that the lower activated carbon rack 4 can be vibrated, which can increase the density of the activated carbon, and at the same time reduce the impact of the airflow of the organic waste gas on the activated carbon, making the activated carbon loose, which is conducive to adsorption.

[0053] In the desorption stage, the high-temperature and high-pressure steam is flushed into the shell 3 through the bottom steam treatment mechanism, the steam treatment mechanism in the middle position does not work, and the top steam treatment mechanism absorbs the high-temperature and high-pressure steam to realize circulation. After a period of treatment, the impurities treated by the high-temperature and high-pressure steam will be separated from the activated carbon and will flow along the bottom of the activated carbon placement rack 4, flow out through the sewage outlet 5, flow into the gap between the receiving ring 13, the connecting bearing and the shell 3, and then flow out through the one-way valve. In order to better flow the retained liquid out of the activated carbon placement rack 4, the drive motor 19 can be started, and the upper rotating column 14 is elastically connected to the lower rotating column 14. In addition, the top steam treatment mechanism is not operated, and the middle steam treatment mechanism is operated and steam is pumped out, so that the high-temperature and high-pressure steam does not pass through the upper activated carbon and continues to desorb the lower activated carbon. After that, all steam treatment mechanisms are closed, and the lower activated carbon is subjected to water removal treatment. At the same time, better sewage discharge and desorption can be performed under the action of vibration.
