Referring to fig. 1 and 2, the present invention provides an activated carbon regeneration waste heat recovery device, including:
an exhaust pipe 1 connected to an exhaust port of the activated carbon regeneration reaction apparatus 90;
a steam generator 2 connected to the activated carbon regeneration reaction device 90 and configured to provide superheated steam to the activated carbon regeneration reaction device 90;

the heat exchanger 4 is connected with the exhaust pipe 1 and used for cooling the exhaust gas output by the exhaust pipe 1 through cooling water; the heat exchanger 4 includes a water inlet 401 for connection with an external water supply system, and a water outlet 402 connected with the water storage tank 3 through a first pipe 5.
When the device is used, the water inlet 401 of the heat exchanger 4 is connected with an external water supply system, cooling water is provided by the external water supply system, the waste gas output by the exhaust pipe 1 is cooled through the heat exchanger 4, so that heat in the waste gas is transferred into the cooling water, the cooling water is sent into the water storage tank 3 for storage, and finally the cooling water is supplied into the steam generator 2 to form superheated steam to be input into the activated carbon regeneration reaction device 90 for reaction; thereby realizing the heat recovery and reutilization of the waste gas discharged by the activated carbon regeneration reaction device 90, reducing the energy consumption and reducing the resource waste.
In some embodiments, see fig. 2, the heat exchanger 4 comprises a housing 403, and a spiral heat exchange tube 405 disposed within an interior cavity 404 of the housing 403; the water inlet 401 and the water outlet 402 are both communicated with an inner cavity 404 of the shell 403; two ends of the spiral heat exchange tube 405 extend out of the shell 403, and one end of the spiral heat exchange tube is connected with the exhaust pipe 1. When the exhaust pipe works, the exhaust pipe 1 inputs exhaust gas into the spiral heat exchange pipe 405, and when the exhaust gas flows along the spiral heat exchange pipe 405, the heat is transferred to cooling water in the inner cavity 404 under the heat conduction action of the spiral heat exchange pipe 405; because the spiral heat exchange tube 405 is extended spirally, under the condition that the volume of the inner cavity 404 is fixed, the total length of the spiral heat exchange tube 405 is larger, which is beneficial to prolonging the moving distance of the waste gas in the inner cavity 404, thereby prolonging the heat exchange time of the waste gas and the cooling water, leading the heat in the waste gas to be more fully recovered and improving the recovery rate of the heat.
In some preferred embodiments, see fig. 2, the housing 403 comprises an outer cylinder 406, an inner cylinder 407 coaxially disposed with the outer cylinder 406, an annular top plate 408 connected between an upper end of the outer cylinder 406 and an upper end of the inner cylinder 407, and an annular bottom plate 409 connected between a lower end of the outer cylinder 406 and a lower end of the inner cylinder 407; the spiral heat exchange tube 405 is disposed around the inner cylinder 407. In the casing 403 of this structure, inner chamber 404 is the annular cavity to the inner space of inner chamber 404 can fully be occupied to spiral heat exchange tube 405, and the cooling water that flows into inner chamber 404 can more fully contact with spiral heat exchange tube 405, thereby more heats can be taken away to the cooling water of unit flow, and the cooling effect is better, and heat recovery efficiency is higher.
Further, referring to fig. 2, the water inlet 401 is disposed on the annular top plate 408, the water outlet 402 is disposed on the annular bottom plate 409, and the water inlet 401 and the water outlet 402 are different by 180 ° in the circumferential direction of the housing 403; thereby maximizing the distance between the water inlet 401 and the water outlet 402, and the residence time of the cooling water in the inner cavity 404 is longer, and it is advantageous to prevent a part of the cooling water from staying in the inner cavity 404, thereby improving the heat recovery efficiency.
In order to avoid the loss of the recovered heat through the casing 403 of the heat exchanger 4, a first thermal insulation layer 410 may be disposed on the outer surface of the casing 403, thereby further improving the recovery rate of the heat.

Since the operation of the steam generator 2 is intermittent and the capacity of the water storage tank 3 is limited during the regeneration treatment of the activated carbon, if the external water supply system continuously supplies water to the heat exchanger 4, the flow rate of the cooling water can only be set to be small in order to avoid the water storage tank 3 from being full, so that the heat recovery rate of the exhaust gas is low; here, by returning the water in the water storage tank 3 to the water inlet 401 to circulate, the flow rate of the cooling water in the heat exchanger 4 can be increased, thereby increasing the heat recovery rate.
Further, a check valve 9 is disposed on the second pipe 7, so as to prevent the cooling water input from the external water supply system from flowing into the second pipe 7.
