DETAILED DESCRIPTION

[0025] The embodiment of the utility model provides a segmented waste heat utilization activated carbon regeneration device.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a furnace body 1, a bottom plate 12 and a water pipe 10, the furnace body 1 is provided with an air guide groove 4 and two air inlets 2, a flared pipe 5 is provided on one side of the air guide groove 4, one end of the flared pipe 5 is fixedly connected to an air guide pipe 6, an air extraction pump 7 is fixedly connected to one side of the furnace body 1, the air inlet end of the air extraction pump 7 and one end of the air guide pipe 6 are fixedly connected to a connecting box 8, a plurality of heat exchange tubes 9 are fixedly connected between the two connecting boxes 8, an air outlet end of the air extraction pump 7 is fixedly connected to an air outlet pipe 11, a diverter box 13 is fixedly connected to the top of the bottom plate 12, and a plug-in component is provided between the air outlet pipe 11 and the diverter box 13.

[0027] When the utility model is in use: the water pipe 10 supplies water to the interior of the furnace body 1, which is used to spray the activated carbon inside the multiple storage boxes 14. The principle of wet regeneration of the activated carbon inside the multiple storage boxes 14 inside the furnace body 1 can refer to the existing patent application number: 201820309117.1, an activated carbon regeneration device, which will not be repeated here.

[0028] In the present application, the bottom plate 12 is used to install a cart and a hydraulic lifting device, and supports the needs of plane movement and up and down movement of multiple storage boxes 14 fixedly installed on the top of the bottom plate 12 through the diverter box 13. When the bottom plate 12 moves to the bottom of the furnace body 1, the hydraulic lifting device is controlled to push the bottom plate 12 to the bottom of the furnace body 1, so that the bottom plate 12 is close to the bottom of the furnace body 1, so as to avoid the heat generated by the internal operation of the furnace body 1 from escaping and reduce the impact on the environment. At this time, multiple storage boxes 14 and the activated carbon stored in the storage boxes 14 enter the furnace body 1 and are processed. The furnace body 1 works and controls the vacuum pump 7 to work at the same time. The flaring pipe 5 is fixedly connected to the furnace body 1, and one end of the flaring pipe 5 is fixedly connected to the air guide pipe 6. The vacuum pump 7 is fixedly connected to one side of the furnace body 1. The air inlet end of 7 and one end of the air guide pipe 6 are fixedly connected with a connecting box 8, and a plurality of heat exchange tubes 9 are fixedly connected between the two connecting boxes 8, so the vacuum pump 7 works to extract air from the inside of the air guide groove 4 through the two connecting boxes 8, a plurality of heat exchange tubes 9, the air guide pipe 6 and the expanding tube 5. A partition plate 3 is arranged between the two air inlets 2, and the partition plate 3 is fixedly connected to the furnace body 1. The partition plate 3 separates the airflow entering the inside of the air guide groove 4 through the two air inlets 2, so that the airflow entering the inside of the air guide groove 4 through the two air inlets 2 flows to the expanding tube 5 through the two sides of the air guide groove 4, thereby ensuring the contact area between the airflow and the furnace body 1, ensuring the heating effect of the heat inside the furnace body 1 on the airflow, playing a role in cooling the surface of the furnace body 1, and reducing the surface temperature value of the furnace body 1. One end of the water pipe 10 extends through the furnace body 1 to the interior of the furnace body 1. The water pipe 10 serves to supply water for spraying multiple storage boxes 14 for hot processing of activated carbon. Since multiple heat exchange tubes 9 all penetrate the water pipe 10, hot air from the multiple heat exchange tubes 9 exchanges heat with water in the water pipe 10 to heat the water in the water pipe 10. The heat generated by the activated carbon processing in the furnace body 1 is used to heat the water in the water pipe 10, thereby reducing the temperature difference between the water sprayed on the activated carbon and the activated carbon, and reducing the breakage of the outer wall due to excessive temperature difference during the processing of the activated carbon. The hot air extracted by the vacuum pump 7 is discharged through the outlet pipe 11 fixedly connected to the outlet end.

[0029] And the connecting pipe 18 in the plug-in assembly is fixedly connected to the shunt box 13, so the connecting pipe 18 and the shunt box 13 move up synchronously, the mounting frame 16 to which one end of the connecting pipe 18 is fixedly connected moves up synchronously, and the fixed box 15 fixedly connected to the top of the mounting frame 16 moves up. Since the rubber tube 17 fixedly connected inside the fixed box 15 is arranged at the bottom of the outlet pipe 11, after the bottom plate 12 is moved up, the rubber tube 17 is sleeved on the outside of the outlet pipe 11, and the rubber tube 17 is deformed to ensure the sealing between the fixed box 15 and the outlet pipe 11. The hot air discharged from the air outlet pipe 11 enters the diversion box 13 through the fixed box 15, the mounting frame 16 and the connecting pipe 18, and multiple storage boxes 14 are each provided with multiple L-shaped elbows 19, the bottom ends of the L-shaped elbows 19 extend to the diversion box 13 and are fixedly connected to the diversion box 13, so the hot air is discharged into the bottom of the inner cavity of the storage box 14 through the multiple L-shaped elbows 19, the hot air heats the activated carbon at the bottom of the inner cavity of the storage box 14, and preheats the activated carbon inside the storage box 14, so as to avoid rapid heating of the activated carbon inside the storage box 14, which may cause external cracking, and ensure the quality of activated carbon processing.

[0030] A sealing block 20 is fixedly connected between the outside of the L-shaped bend 19 and the diversion box 13. The sealing block 20 fills the space between the L-shaped bend 19 and the diversion box 13 to prevent the L-shaped bend 19 from preventing the activated carbon from being discharged from the storage box 14. A filter screen 21 is fixedly connected to one side of the inside of the L-shaped bend 19. When processing smaller activated carbon, the filter screen 21 is installed inside multiple L-shaped bends 19 to prevent the activated carbon from entering the L-shaped bend 19 and being unable to be discharged from the storage box 14.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
