Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon regeneration, in particular to an activation furnace for activated carbon regeneration. Background Art

[0002] Activated carbon regeneration method, activated carbon regeneration is to reactivate the fully adsorbed activated carbon after being treated under certain conditions. Activated carbon has been widely used in environmental protection, industry and civil use, and has achieved considerable results. However, after the activated carbon is replaced after adsorption saturation, the use of activated carbon adsorption is a physical process. Therefore, high-temperature steam can also be used to desorb the impurities in the used activated carbon and restore its original activity to achieve the purpose of reuse, which has obvious economic benefits. The regenerated activated carbon can still be reused and regenerated continuously. Activated carbon regeneration is to reactivate the fully adsorbed activated carbon after being treated under certain conditions.

[0003] For example, patent application number CN202020058989.2 discloses an activated carbon activation and regeneration device, which includes a furnace body assembly, an activation heating assembly and an activated carbon support assembly. The activation heating assembly is arranged below the furnace body assembly, and multiple activated carbon support assemblies can be placed at one time through the three-dimensional activation furnace, so that more activated carbon can be activated and regenerated at the same time. At the same time, the activated carbon support assembly at the bottom can be pulled out, and the activated carbon support assembly with activated carbon placed on it can be added to the interior of the activation furnace again from the feed port at the top of the activation furnace, so that the activated carbon can be continuously activated and regenerated, which greatly improves the treatment efficiency, and each activated carbon can be effectively treated through the placement plate in the activated carbon support assembly, resulting in better effect of activated carbon activation and regeneration.

[0004] Based on the above search, combined with the prior art, it is found that the internal bottom side of the activated carbon activation and regeneration device similar to the above disclosed in the prior art lacks a buffer structure. After taking out the lowermost placement plate, the upper placement plate will fall rapidly under the action of gravity, and violently collide with the bottom of the device, which is easy to damage the device; in addition, the support feet of the placement plate are set so that the high-temperature steam inside the device will overflow from the feeding port and the feeding port. Even if a sealing door is set at the feeding port and the feeding port, the sealing door needs to be frequently opened and closed before and after loading and unloading, which is relatively cumbersome. Therefore, an activation furnace for activated carbon regeneration is proposed to improve the above problems. Utility Model Content

[0027] The activated carbon to be treated is placed in a placement frame 6, and the placement frame 6 is stacked inside the furnace body 1 through the discharge port 7. The heating device 4 is started to heat the water in the furnace body 1 so that the water generates high-temperature steam, and the high-temperature steam activates the activated carbon. When taking it out, a placement frame 6 at the lowest end of the furnace body 1 is taken out through the feeding port 8. At this time, the other stacked placement frames 6 are moved down as a whole, and the placement frame 6 with activated carbon placed can be added again from the discharge port 7 on the top of the furnace body 1 to the inside of the furnace body 1, so as to realize continuous activation and regeneration of the activated carbon.

[0028] A dispersion plate 5 and a buffer plate 10 are provided on the upper side of the heating device 4, and both the dispersion plate 5 and the buffer plate 10 are densely covered with pores. The dispersion plate 5 is located on the lower side of the buffer plate 10, and the dispersion plate 5 is fixed to the inner wall of the furnace body 1. The buffer plate 10 is in sliding contact with the inner wall of the furnace body 1, and a buffer spring 11 is fixed between the buffer plate 10 and the dispersion plate 5. A high-temperature resistant buffer gasket 20 is fixedly connected to the upper end of the placement frame 6.

[0029] By setting the buffer plate 10 and the buffer spring 11, when a placement frame 6 at the lowest end of the furnace body 1 is taken out, the other stacked placement frames 6 fall onto the buffer plate 10 as a whole, and cooperate with the buffer spring 11 to achieve a good buffering effect to avoid damage caused by severe impact. In addition, the high-temperature resistant buffer gasket 20 set at the upper end of the placement frame 6 can achieve a buffering effect between two adjacent placement frames 6 to better protect the placement frame 6.

[0030] The placement frame 6 is a frame-shaped frame with air holes densely distributed on the bottom, and the two side frames of the placement frame 6 corresponding to the discharge port 7 and the material taking port 8 can seal the discharge port 7 and the material taking port 8 to prevent high-temperature steam from overflowing from the furnace body 1. Before and after placing the placement frame 6, there is no need to perform additional sealing operations on the discharge port 7 and the material taking port 8. The structure is simple and the operation is convenient.

[0031] Furthermore, both the discharge port 7 and the take-out port 8 are provided with limit frames 9 , which are fixed on the outer wall of the furnace body 1 , so as to facilitate the placement frame 6 during the process of taking and placing the placement frame 6 .

[0032] Among them, a plurality of heat-conducting columns 12 are evenly fixed on the inner bottom end of the placement frame 6, and a lifting plate 13 is provided on the inner bottom end of the placement frame 6.

In order to quickly remove the activated carbon blocks stuck between adjacent heat-conducting columns 12 and the activated carbon blocks attached to the bottom of the frame, the cross bar 16 can be manually pulled upwards. The cross bar 16 moves up with the lifting plate 13 through the sliding sleeve 15, and the activated carbon blocks are brought upwards. At this time, the activated carbon can be quickly taken out. The coordinated setting of the sliding column 17, the limiting sliding block 19 and the limiting sliding groove 18 can effectively prevent the lifting plate 13 from detaching from the heat-conducting column 12.

When taking it out, a placement frame 6 at the lowest end of the furnace body 1 is taken out through the material taking port 8. At this time, the other stacked placement frames 6 move downward as a whole, and the placement frame 6 with activated carbon placed can be added to the inside of the furnace body 1 again from the discharge port 7 at the top of the furnace body 1, so as to realize continuous activation and regeneration of the activated carbon; wherein, through the buffer plate 10 and the buffer spring 11 are set, when a placement frame 6 at the lowest end of the furnace body 1 is taken out, the other stacked placement frames 6 fall on the buffer plate 10 as a whole, and the buffer spring 11 can achieve a good buffering effect to avoid damage caused by severe impact. In addition, the high-temperature resistant buffer gasket 20 set at the upper end of the placement frame 6 can achieve a buffering effect between two adjacent placement frames 6, so as to better protect the placement frame 6; when the activated carbon in the placement frame 6 needs to be taken out, the cross bar 16 is manually pulled up, and the cross bar 16 moves up with the lifting plate 13 through the sliding sleeve 15, and the activated carbon block is brought up and out, and the activated carbon can be quickly taken out at this time.
