Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon regeneration equipment, and in particular to a cooling device for activated carbon regeneration. Background Technology

[0002] Activated carbon is a porous carbon material with extremely high specific surface area and adsorption capacity. It can adsorb impurities, organic matter, heavy metals, etc. in gases or liquids. These impurity molecules enter the micropores of activated carbon and undergo physical or chemical adsorption with the surface of activated carbon. When the adsorption sites on the surface of activated carbon are completely occupied, it reaches the adsorption saturation state. In this state, activated carbon can no longer adsorb more impurities, and even if it continues to come into contact with a medium containing impurities, there will be no obvious adsorption effect.

[0003] Activated carbon regeneration is a process that restores the adsorption properties of used activated carbon. Regeneration can extend the service life of activated carbon, reduce operating costs, and reduce waste disposal.

[0004] The utility model patent with publication number CN221071041U discloses an activated carbon cooling rotary furnace, including a rotary furnace body and a cooling tank. The bottom of the cooling tank is provided with a support block. The rotary furnace is cylindrical in shape and movably connected to the support block. The cooling tank is provided with a water inlet and a water outlet. Both the water inlet and the water outlet are provided with one-way control valves to solve the problems of low natural cooling efficiency after activated carbon carbonization and the dangerous removal and transportation process in the existing methods of removing high-temperature activated carbon for cooling.

[0042] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] like Figure 1-7 As shown, the present invention provides a cooling device for activated carbon regeneration, comprising a base 1, a roller 2, a cooling mechanism 3, a circulation mechanism 4, a drive device 5, and a hopper 6.

[0044] The base 1 is used to support the roller 2, the circulation mechanism 4 and the drive device 5.

[0045] The roller 2 is used to hold activated carbon, and the roller 2 is driven to rotate by the drive device 5 to turn the activated carbon. In order to achieve the rotation of the roller 2, a toothed ring 51 is set at one end of the roller 2. The toothed ring 51 is set on the base 1 through a bearing seat. The base 1 is also equipped with a roller to support the end of the roller 2 away from the toothed ring 51.

[0046] Cooling mechanism 3 is used to cool the activated carbon inside drum 2, such as Figure 4 As shown, the cooling mechanism 3 includes a return water pipe 31, a return water pipe 32, an inlet water pipe 33, an inlet water pipe 34, and a cooling pipe 35. The return water pipe 31 is a tubular structure with one end closed. The return water pipe 31 passes through the gear ring 51 and is rotatably connected to the gear ring 51, so that the return water pipe 31 does not rotate with the rotation of the roller 2. The return water pipe 32 is fixedly installed on the outer wall of the return water pipe 31, and the two are connected. The inlet water pipe 33 is a tubular structure with both ends closed to prevent cooling water from leaking from both ends of the inlet water pipe 33. A round hole is opened in the middle of the closed end of the return water pipe 31. One end of the inlet water pipe 33 is inserted into the interior of the return water pipe 31 through the round hole and is fixedly connected to the return water pipe 31 to prevent leakage at the connection between the inlet water pipe 33 and the return water pipe 31. The inlet water pipe 33 and the return water pipe 31 are spaced apart to leave a gap between the inlet water pipe 33 and the return water pipe 31, so as to realize the return of cooling water.

[0047] The inlet water pipe 34 is fixedly installed on the outer wall of the end of the inlet water pipe 33 away from the return water pipe 32, and the inlet water pipe 34 is connected to the inlet water pipe 33. Multiple return water pipes 32 and multiple inlet water pipes 34 are provided, and the multiple return water pipes 32 and multiple inlet water pipes 34 are arranged in a circumferential array around the center line of the return water pipe 31 and correspond one to one. The two ends of the cooling pipe 35 are respectively connected to the interior of the inlet water pipe 34 and the return water pipe 32. Cooling water flows into the inlet water pipe 34 through the inlet water pipe 33 to realize the diversion of cooling water, and then flows from the inlet water pipe 34 through the cooling pipe 35 and back to the return water pipe 32. The activated carbon is in direct contact with the cooling pipe 35, and the heat is carried away by the cooling water. Finally, it flows into the return water pipe 31. Multiple cooling pipes 35 are provided between the return water pipe 32 and the inlet water pipe 34 to increase the distribution range of the cooling pipes 35, thereby increasing the contact area with the activated carbon and improving the cooling efficiency of the activated carbon.

[0048] In order to ensure that the activated carbon in the drum 2 can flow normally, multiple cooling pipes 35 are arranged in parallel and at intervals, leaving gaps between the cooling pipes 35 to prevent material from accumulating inside.

[0049] To prevent deformation of the return water pipe 31, and to improve the load-bearing capacity, support strength, and stability of the inlet water pipe 33, such as Figure 5 As shown, the cooling mechanism 3 also includes a support plate 36, which is fixedly installed between the return water pipe 31 and the inlet water pipe 33. The return water pipe 31 is supported by the support plate 36, and multiple support plates 36 are arranged in a circumferential array around the center line of the return water pipe 31 to avoid obstructing the normal flow of cooling water.

[0050] The circulation mechanism 4 is used to cool the drum 2 and the cooling water. The circulation mechanism 4 includes a cooling tank 41, a support 42, a spray pipe 43 and a water pump 44. The cooling tank 41 is fixedly installed inside the base 1 and is used to hold the cooling water. The heat carried by the activated carbon will be transferred to the drum 2, causing the temperature of the drum 2 to rise. The lower part of the drum 2 is immersed in the cooling tank 41. As the drum 2 rotates, the heat is carried away by the cooling water, thereby cooling the drum 2.

[0051] The bracket 42 is fixedly installed on the top of the base 1, which supports the spray pipe 43. The spray pipe 43 is fixedly installed on the top of the bracket 42 and is located above the roller 2. The spray pipe 43 sprays cooling water onto the surface of the roller 2, which can further cool the roller 2. The cooling water cools down during the flow process, improving the overall cooling effect. The water pump 44 is fixedly installed on the top of the base 1, and the input end of the water pump 44 is located in the cooling tank 41. The output end of the water pump 44 is connected to the water supply pipe 37 and the spray pipe 43 through a T-junction. The water pump 44 delivers the cooling water in the cooling tank 41 to the water supply pipe 37 and the spray pipe 43, realizing the circulation of cooling water.

[0052] The cooling mechanism 3 also includes a water supply pipe 37 and a guide pipe 38. A round hole is provided on the outer wall of the return water pipe 31. The water supply pipe 37 passes through the round hole and is fixedly connected to the round hole. The water supply pipe 37 is located outside the roller 2 and is connected to the inside of the inlet water pipe 33 to deliver cooling water to the inlet water pipe 33. The guide pipe 38 is fixedly installed at one end of the opening of the return water pipe 31 and is perpendicular to the return water pipe 31 and the two are connected. The cooling water in the return water pipe 31 is introduced into the cooling tank 41 through the guide pipe 38 to prevent the cooling water from spraying out.

[0053] Drive unit 5 is used to drive the rotation of roller 2, such as Figure 7 As shown, the drive device 5 also includes a motor base 52, a reduction motor 53, and a drive gear 54. The motor base 52 is fixedly mounted on the top of the base 1, and the reduction motor 53 is fixedly mounted on the motor base 52. The drive gear 54 is fixedly mounted on the output end of the reduction motor 53, and the drive gear 54 meshes with the gear ring 51. The reduction motor 53 drives the gear ring 51 to rotate through the drive gear 54, thereby realizing the rotation of the roller 2.

[0054] The hopper 6 is used for feeding and discharging. The hopper 6 is located at the end of the drum 2 away from the toothed ring 51. The hopper 6 is provided with a feed inlet 601 and a discharge outlet 602, which are located at the top and bottom of the hopper 6, respectively. The end of the drum 2 away from the toothed ring 51 is provided with a feed inlet 201, and the discharge outlet 602 is connected to the feed inlet 201. In order to achieve discharge, a spiral auger blade is provided on the inner wall of the hopper 6. When the drum 2 rotates in the forward direction, the activated carbon will not leak out from the feed inlet 201. When the drum 2 rotates in the reverse direction, the activated carbon is pushed to the discharge outlet 602 by the action of the auger blade on its inner wall and discharged from the drum 2 through the discharge outlet 602. This technology is existing technology. The auger blade should avoid contact with the cooling mechanism 3 to prevent collision between the two.

[0055] The method of using the cooling device for activated carbon regeneration according to this utility model is as follows:

[0056] First, inject an appropriate amount of cooling water into the cooling tank 41, ensuring that the lower part of the drum 2 is immersed in the cooling water. Activated carbon is then poured into the drum 2 through the feed port 601. The drive device 5 drives the drum 2 to rotate, thereby agitating the activated carbon. During this process, the water pump 44 delivers the cooling water in the cooling tank 41 to the cooling mechanism 3 and the spray pipe 43. The cooling mechanism 3 cools the activated carbon in the drum 2, while the cooling water sprayed from the spray pipe 43 cools the drum 2 and the cooling water at the same time, thus achieving the cooling of the activated carbon. After the activated carbon has cooled, the drum 2 rotates in the reverse direction, discharging the activated carbon from the discharge port 602.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
