Description

Technical Field

[0001] This application relates to the technical field of waste-to-energy plants, and in particular to an activated carbon feeding device for waste-to-energy plants. Background Technology

[0002] Currently, the conventional method for waste-to-energy plants to adsorb residual heavy metals and dioxins from flue gas is through activated carbon technology. During continuous production, activated carbon needs to be continuously injected to complete the adsorption, and the activated carbon needs to be unloaded from the purchased packaged activated carbon into the activated carbon silo.

[0003] In related technologies, activated carbon packaging bags are manually opened on-site and poured into a transfer warehouse. Then, the activated carbon is pumped into the activated carbon warehouse. However, in order to improve the adsorption effect and increase the contact area of ​​the activated carbon, the activated carbon used to adsorb flue gas is fine powder, which is very easy to generate dust. Therefore, the on-site environment for manual unpacking is extremely poor, and the occupational health and safety of workers cannot be guaranteed. Moreover, the loss of activated carbon in the long-term continuous production process cannot be ignored. Utility Model Content

[0004] The purpose of this application is to provide an activated carbon feeding device for waste incineration power plants, in order to solve the problems of extremely poor working conditions at manual unpacking sites, the inability to guarantee the occupational health and safety of workers, and the significant losses of activated carbon carried away during long-term continuous production.

[0005] The activated carbon feeding equipment for a waste-to-energy plant provided in this application adopts the following technical solution:

[0006] An activated carbon feeding device for a waste incineration power plant includes a discharge hopper, a transfer hopper at the bottom of the discharge hopper, and the discharge hopper and the transfer hopper are internally connected. A grid plate for supporting activated carbon packaging bags is provided between the inner sides of the discharge hopper and the transfer hopper. An operating device for cutting open the activated carbon packaging bags is provided on one side of the discharge hopper. A conveying device is provided at the bottom of the transfer hopper, and the output end of the conveying device is connected to the input end of an external activated carbon hopper.

[0007] Furthermore, the unloading hopper is provided with symmetrical operating hand holes on one side. The operating device includes operating gloves respectively disposed inside the two operating hand holes. The operating gloves are inserted into the operating hand holes and located inside the unloading hopper. An observation window is also provided on one side of the unloading hopper.

[0008] Furthermore, a tool hook is provided on one side of the unloading hopper, and a tool is hung on the tool hook.

[0009] Furthermore, the conveying device includes a pneumatic diaphragm pump disposed between the spare compartment and the activated carbon compartment. The input end of the pneumatic diaphragm pump is connected to the bottom of the spare compartment through a conveying pipe, and the output end of the pneumatic diaphragm pump is connected to the top of the activated carbon compartment through an output pipe.

[0010] Furthermore, the grid plate has a number of mesh holes.

[0011] Furthermore, the top of the unloading hopper is provided with a loading and unloading port, and a sealing cover is hinged to one side of the loading and unloading port. A sealing device is provided between the sealing cover and the unloading hopper.

[0012] Furthermore, the sealing device includes a sealing frame strip disposed on one side of the closed cover plate, a sealing protrusion strip disposed on one side of the sealing frame strip, and a sealing groove that cooperates with the sealing protrusion strip is provided on the top of the unloading bin.

[0013] Furthermore, a handle is provided on the surface of the closed cover.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: by setting up a structure in which the unloading bin, the transfer bin, the grid plate, the operating device and the conveying device cooperate with each other, it is possible to achieve contactless unloading during the process of "unloading activated carbon packaging bags" in which activated carbon is raised and workers have the closest contact. The unpacked activated carbon is then centrally stored in the transfer bin, and the activated carbon in the transfer bin is then intermittently extracted to the activated carbon bin for spraying using the conveying device. This ensures a good working environment at the manual unpacking site, protects the occupational health of workers, and reduces the loss of activated carbon. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] This application discloses an activated carbon feeding device for a waste incineration power plant, referring to... Figure 1 and Figure 2 In this embodiment, the activated carbon feeding equipment for the waste-to-energy plant includes an unloading hopper 1, a transfer hopper 2, a grid plate 3, an operating device, and a conveying device. The unloading hopper 1 is installed inside the waste-to-energy plant via a support frame. The transfer hopper 2 is installed at the bottom of the unloading hopper 1, with its top connected to the bottom of the unloading hopper 1. The transfer hopper 2 has a funnel-shaped structure, facilitating the collection and storage of activated carbon.

[0021] Preferably, in this embodiment, a loading / unloading port 12 is provided at the top of the unloading hopper 1 opposite to the transfer hopper 2. A sealing cover 7 is hinged to one side of the loading / unloading port 12. The sealing cover 7 is used to cover the top of the unloading hopper 1 to seal the loading / unloading port 12, thereby preventing the activated carbon from being lifted and floating out of the unloading hopper 1. At the same time, a handle 8 is also installed on the surface of the sealing cover 7. The handle 8 makes it easy to flip and open the sealing cover 7 to place the activated carbon packaging bag into the unloading hopper 1.

[0022] And refer to Figure 1 and Figure 2 In this embodiment, a sealing device is also provided between the closed cover plate 7 and the unloading bin 1. This sealing device can more tightly seal the closed cover plate 7 onto the top of the unloading bin 1. Specifically, the sealing device includes a sealing frame strip 71 and a sealing protrusion strip 72. The sealing frame strip 71 is installed around the inner side of the closed cover plate 7; when the closed cover plate 7 is closed onto the top of the unloading bin 1, the sealing frame strip 71 abuts against the top side of the unloading bin 1.

[0023] The sealing protrusion 72 is installed on the side of the sealing frame 71 away from the sealing cover 7, and a sealing groove 13 is provided on the top of the unloading bin 1. The sealing groove 13 cooperates with the sealing protrusion 72. When the sealing frame 71 abuts against the top side of the unloading bin 1, the sealing protrusion 72 is inserted into the sealing groove 13, thereby further improving the sealing degree between the sealing cover 7 and the unloading bin 1.

[0024] At the same time, refer to Figure 1 In this embodiment, the grid plate 3 is installed between the inner sides of the unloading bin 1 and the transfer bin 2. When the worker places the activated carbon packaging bag into the unloading bin 1, the grid plate 3 can not only support the activated carbon packaging bag to facilitate subsequent cutting, but also reduce the worker's workload during unloading. Furthermore, the grid plate 3 has several mesh holes 31. Through these mesh holes 31, after the activated carbon packaging bag is cut open, the activated carbon is poured into the transfer bin 2 directly below, thus achieving the collection and storage of activated carbon.

[0025] Additionally, refer to Figure 1 In this embodiment, the operating device is located on one side of the unloading hopper 1 for cutting open activated carbon packaging bags placed on the grid plate 3. Specifically, the operating device includes operating gloves 4 and observation windows 5. Operating hand holes 11 are symmetrically provided on one side of the unloading hopper 1. Two operating gloves 4 are provided, with the openings of the two gloves respectively installed inside the two operating hand holes 11, and the two gloves 4 are inserted into the two operating hand holes 11 and located inside the unloading hopper 1.

[0026] This not only allows workers to insert their hands into two operating gloves 4 to facilitate the subsequent process of cutting open the activated carbon packaging bags, but also allows workers to complete the unloading process with large movements without worrying about dust, thus improving unloading efficiency, since they do not come into direct contact with the activated carbon throughout the unloading process.

[0027] The observation window 5 is installed on one side of the unloading hopper 1 and is located on the same side as the operating handhole 11. The observation window 5 allows the worker to see the environment inside the unloading hopper 1. A knife hook is also installed on one side inside the unloading hopper 1. A knife is hung on the knife hook and is used to cut open the activated carbon packaging bag.

[0028] In this way, by using the observation window 5, along with the operating gloves 4 and the knives prepared inside the unloading bin 1, the worker can cut open the activated carbon packaging bags inside the unloading bin 1. This ensures contactless unloading during the process of "unloading activated carbon packaging bags," in which the activated carbon is thrown up and the worker has the closest contact with it. The unpacked activated carbon is then stored in the transfer bin 2 along the mesh 31.

[0029] In addition, refer to Figure 1 In this embodiment, the conveying device is located at the bottom of the standby chamber 2, and the output end of the conveying device is connected to the input end of the external activated carbon chamber to extract the activated carbon stored in the standby chamber 2 into the activated carbon chamber for storage and processing.

[0030] Specifically, the conveying device includes a pneumatic diaphragm pump 6, a conveying pipe 61, and an output pipe 62. The pneumatic diaphragm pump 6 is positioned between the standby chamber 2 and the activated carbon chamber. One end of the conveying pipe 61 is connected to the input end of the pneumatic diaphragm pump 6, and the other end is connected to the bottom of the standby chamber 2. One end of the output pipe 62 is connected to the output end of the pneumatic diaphragm pump 6, and the other end is connected to the top of the activated carbon chamber.

[0031] When the pneumatic diaphragm pump 6 is started, the activated carbon in the standby chamber 2 is extracted through the delivery pipe 61, and then the activated carbon is extracted into the activated carbon chamber through the output pipe 62 for storage.

[0032] The implementation principle of an activated carbon feeding device for a waste incineration power plant according to an embodiment of this application is as follows:

[0033] The worker first opens the sealing cover 7, then places the activated carbon packaging bag onto the grid plate 3 inside the unloading hopper 1, and then closes the sealing cover 7. Using the observation window 5, operating gloves 4, and the knife prepared inside the unloading hopper 1, the worker cuts open the activated carbon packaging bag placed on the grid plate 3, allowing the activated carbon to be poured into the transfer hopper 2 directly below through the mesh holes 31 on the grid plate 3. Then, the worker starts the pneumatic diaphragm pump 6, which, through the cooperation of the delivery pipe 61 and the output pipe 62, intermittently extracts the activated carbon into the activated carbon hopper for storage, to be used for spraying later.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
