[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-5 A novel activated carbon regeneration tower includes a regeneration tower body 1, a feed port 2 is provided at the top of the regeneration tower body 1, a discharge port 3 is provided below the regeneration tower body 1, and a preheating section 4, a heating section 5, a first cooling section 6, and a second cooling section 7 are sequentially arranged in the regeneration tower body 1 from top to bottom between the feed port 2 and the discharge port 3. The multi-stage heating and cooling arrangement facilitates ensuring heating and cooling effects;

[0024] The preheating section 4 and the heating section 5 are connected together, and heat exchangers are provided in the preheating section 4, the heating section 5, the first cooling section 6 and the second cooling section 7, and the preheating section 4 and the heating section 5 share one heat exchanger;

[0025] The heat exchanger includes a cylinder 8, which has a hollow structure and is made of copper. Several penetration tubes 9 are provided through the cylinder 8, and the penetration tubes 9 are made of copper. A heat exchange medium input tube 10 and an output tube 11 are provided on the outside of the cylinder 8, and the heat exchange medium input tube 10 is located below the corresponding output tube 11.

[0026] In use, the device can complete preheating and cooling by sequentially passing through the preheating section 4, the heating section 5, the first cooling section 6 and the second cooling section 7 after the waste activated carbon is put into the regeneration tower body 1 from the feed inlet 2, and the purpose of heating and cooling is achieved by adding a heat source or a cold source to the inside of the cylinder 8 to complete heat exchange with the waste activated carbon. Compared with the prior art, the device has a compact structure, uniform heat exchange can be achieved through the feeding pipe 9, and the movement trajectory of the activated carbon is vertical, which is suitable for the demand of large-scale and high-efficiency regeneration of activated carbon.

[0027] In the embodiment, the upper part of the preheating section 4 and the lower part of the heating section 5 are both provided with a flower plate 12 installed inside the regeneration tower body 1, a plurality of gas distribution pipes 13 are vertically arranged on the two flower plates 12, and gaps exist between the plurality of gas distribution pipes 13. One side of the gas distribution pipe 13 of the upper flower plate 12 is provided with a first inert gas inlet pipe 14 communicating with the inside of the regeneration tower, one side of the gas distribution pipe 13 of the lower flower plate 12 is provided with a second inert gas inlet pipe 15 communicating with the inside of the regeneration tower, and the other side of the gas distribution pipe 13 of the lower flower plate 12 is provided with an inert gas outlet pipe 16 communicating with the inside of the regeneration tower. After the activated carbon falling in the regeneration tower passes through the gas distribution pipe 13 and reaches the lower part of the gas distribution pipe 13, the activated carbon, which is a solid material, will not be in the gap between the two gas distribution pipes 13 due to the effect of the angle of repose. At this time, the heating section 5 in the regeneration tower heats the activated carbon, and the organic matter in the activated carbon is evaporated into the gap between the two gas distribution pipes 13. At this time, inert gas can be sent into the gap by cooperating with an external device to realize the carrier gas process of waste gas. The inert gas carries the waste gas from the first inert gas inlet pipe 14 to the second inert gas inlet pipe 15, and the second inert gas inlet pipe 15 also completes the above process. At this time, the inert gas can be extracted by cooperating with an external device, which realizes the uniform distribution of waste gas and is beneficial to uniform carrier gas and ensures the regeneration effect of activated carbon.

[0028] In the embodiment, the inert gas outlet pipe 16 is connected with an air extraction device 17 through a pipeline, and the air extraction device 17 is a fan for extracting the inert gas.

[0029] In the embodiment, a plurality of gas distribution pipes 13 form a plurality of annular array groups arranged on the flower plate 12, and the spacing of the plurality of annular array groups is the same, which facilitates the uniform distribution of gas in each gap.

[0030] In the embodiment, the first inert gas inlet pipe 14 is horizontally arranged at the center of the corresponding gas distribution pipe 13, so as to facilitate the inert gas to be sent into the gas distribution pipe 13; the bottom of the second inert gas inlet pipe 15 is horizontally arranged at the bottom of the corresponding gas distribution pipe 13; and the bottom of the inert gas outlet pipe 16 is horizontally arranged at the bottom of the corresponding gas distribution pipe 13, so as to facilitate the inert gas to be sent into the gas distribution pipe 13 and to be discharged by the inert gas outlet pipe 16.

[0031] In the embodiment, the diameter of the feed pipe 9 is larger than that of the gas distribution pipe 13, so as to facilitate the waste activated carbon to be sent into the feed pipe 9 from the gas distribution pipe 13.

Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
