[0002] Activated carbon is a specially treated type of carbon. Organic raw materials are heated in the absence of air to reduce non-carbon components, then react with gases, causing surface erosion and creating a highly porous structure. Because the activation process is microscopic—the erosion of numerous molecular carbides is point-like—the activated carbon surface has countless tiny pores.

[0003] In the production process of existing activated carbon, the surface pores grow slowly, which easily leads to insufficient activation and low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a production device for promoting the growth of activated carbon pores. It uses an air pump to fill the inside of an externally insulated tank with air, preheats the air, and then injects it into the inner liner. The tank is then heated again and the raw material is carbonized on the surface under high temperature. In addition, the carbon monoxide and carbon dioxide generated during the carbonization process can continue to react with the raw material at high temperature inside, promoting the growth of carbonized pores, increasing the pore growth rate, and improving the uniformity of activation.

There are two internal temperature sensors, which are symmetrically distributed at the upper and lower ends of the internal heating plate.

[0006] According to the aforementioned equipment for promoting activated carbon pore growth, the output end of the air pump passes through the outer barrel and the outer insulation barrel, and a cavity is provided between the outer insulation barrel and the inner insulation barrel.

[0007] According to the aforementioned equipment for promoting activated carbon pore growth, an upper air pipe is fixedly connected to the top of the inner liner, and the top of the upper air pipe penetrates the inner heat insulation barrel.

[0008] According to the aforementioned equipment for promoting activated carbon pore growth, a feed pipe is fixedly connected to the top of the outer barrel, and the bottom of the feed pipe passes through the outer insulation barrel and the inner insulation barrel and is fixedly connected to the inner liner.

[0009] According to the activated carbon pore growth production equipment, the bottom of the outer barrel is fixedly connected to a discharge pipe, and the top of the discharge pipe passes through the outer insulation barrel, the inner insulation barrel, the inner liner and the mesh barrel and is fixedly connected.

[0023] Reference Figure 1-4This utility model embodiment of a production equipment for promoting activated carbon pore growth includes: an outer barrel 1; an outer heat-insulating barrel 2 fixedly connected to the inner circumferential surface of the outer barrel 1; an inner heat-insulating barrel 3 disposed inside the outer heat-insulating barrel 2; an inner liner 4 fixedly connected to the inner circumferential surface of the inner heat-insulating barrel 3; and an inner heating plate 5 fixedly connected to the inner circumferential surface of the inner liner 4. Activating the inner heating plate 5 provides the high-temperature environment required for activation, allowing the internal gas to activate the surface of the raw materials. A mesh barrel 6, made of stainless steel, is disposed inside the inner heating plate 5 for placing the raw materials. The top of the mesh barrel 6 is fixedly connected to the inner liner 4. A lower heating plate 7 is fixedly connected to the inner bottom surface of the outer heat-insulating barrel 2. Activating the lower heating plate 7 preheats the air inside the cavity. Eight lower air pipes 8 are fixedly connected to the bottom of the inner liner 4. The bottom of the inner liner 4 is evenly distributed. A valve is provided on the circumference of the lower air pipe 8. When the valve is opened, preheated air can be injected into the inner liner 4 through the lower air pipe 8. After reheating, the raw materials are surface activated. An external temperature sensor 9 and a pressure sensor 10 are fixedly connected to the inner circumference of the outer heat insulation barrel 2. There are two external temperature sensors 9, which are symmetrically arranged at the top and bottom, and are used to monitor the air pressure and temperature in the cavity. An internal temperature sensor 12, an internal carbon monoxide sensor 13, and an internal carbon dioxide sensor 14 are fixedly connected to the inner circumference of the inner liner 4. They are used to monitor the concentration and temperature of carbon monoxide and carbon dioxide in the inner liner 4. There are two internal temperature sensors 12, which are symmetrically distributed at the top and bottom ends of the inner heating plate 5. An air pump 15 is fixedly connected to the circumference of the outer barrel 1.

[0024] The output end of the air pump 15 passes through the outer barrel 1 and the outer insulation barrel 2. A cavity is provided between the outer insulation barrel 2 and the inner insulation barrel 3. The air pump 15 can be used to fill the cavity inside the outer insulation barrel 2 with air to facilitate preheating.

[0025] The top of the inner liner 4 is fixedly connected to an upper air pipe 18, the top of which passes through the inner heat insulation barrel 3 and communicates with the cavity, thereby forming an internal circulation. This allows the carbon monoxide and carbon dioxide generated during the activation process to circulate continuously inside and continue to react with the raw materials under high temperature conditions, thereby promoting the growth of surface pores and making the activation more complete. The top of the outer barrel 1 is fixedly connected to a feed pipe 19, the bottom of which passes through the outer heat insulation barrel 2 and the inner heat insulation barrel 3 and is fixedly connected to the inner liner 4. The bottom of the outer barrel 1 is fixedly connected to a discharge pipe 20, the top of which passes through the outer heat insulation barrel 2, the inner heat insulation barrel 3, the inner liner 4 and the mesh barrel 6 and is fixedly connected to the outer barrel 1. The top of the outer barrel 1 is fixedly connected to an exhaust pipe 21. Both the feed pipe 19 and the discharge pipe 20 are made of non-thermal conductive ceramic material. The bottom of the exhaust pipe 21 passes through the outer heat insulation barrel 2 and is connected to an external cooling device.

[0026] The bottom of the outer tub 1 is fixedly connected to a support column 22. There are four support columns 22, which are symmetrically distributed below the outer tub 1.

[0027] Working principle: Raw materials are fed into the mesh barrel 6 through the feed pipe 19. Then, the air pump 15 is started to inject air into the internal cavity of the outer heat-insulating barrel 2. The lower heating plate 7 is started to preheat the air. Then, the lower air pipe 8 is opened to inject the preheated air into the inner liner 4. The inner heating plate 5 is started to continue to raise the internal temperature and activate the surface of the raw materials. The gas after the reaction enters the cavity again through the upper air pipe 18. The air pump 15 continuously injects cold air to create a large temperature difference between the inside and outside, thereby forming a gas circulation. When the internal air pressure is too high, some gas is discharged from the exhaust pipe 21 into the cooling equipment. After cooling, it is discharged again. After activation is completed, the discharge pipe 20 is opened to discharge the activated carbon.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
