Description

Technical Field

[0001] This utility model relates to the field of activated carbon preparation technology, and in particular to industrial production equipment for activated carbon with rich micropores. Background Technology

[0002] The process of giving carbon particles activity, enabling them to form a porous microcrystalline structure with a large surface area, is called activation. The commonly used activation method for coal-based activated carbon is physical activation. In this method, the carbonized material is activated in an activation furnace by contacting it with water vapor, flue gas (a mixture of water vapor, CO2, N2, etc.), CO2, or air as the activation gas at a high temperature of 800-1000℃ (flue gas is most commonly used in actual production).

[0003] Patent publication number "CN109809406A", entitled "An Activation System for Activated Coke or Activated Carbon", includes a first half-furnace and a second half-furnace with the same structure. The first half-furnace includes a furnace body and a furnace core disposed inside the furnace body. The furnace body is a closed cavity with a feeding port at the top and a discharging port at the bottom. A reprocessing chamber is disposed below the discharging port and connected to the bottom of the furnace body. Several vent pipes for introducing oxygen-containing mixed gas are disposed on the side wall of the reprocessing chamber. The furnace body, from top to bottom, consists of a feeding section, a preheating section, a reaction section, a cooling section, a rapid cooling section, and a discharging section. To ensure pressure balance inside the activation furnace and prevent external gas from entering, a water seal is used to seal the connection between the furnace cover and the furnace body.

[0004] However, the high temperature inside the activation furnace can also heat the sealing water through the gap between the furnace cover and the furnace body, causing the water to evaporate. In order to ensure the water sealing effect, it is necessary to replenish the water when the water level drops, resulting in the activation furnace consuming a large amount of water when it is working. Utility Model Content

[0005] The purpose of this invention is to provide an industrial production equipment for activated carbon with rich micropores. It can supply low-temperature water for sealing to the activation furnace during operation, and cool the hot water in the activation furnace after it is discharged. The cooled water is then used to seal the activation furnace again, which avoids the water temperature in the activation furnace being too high, reduces the evaporation of the sealing water, and thus reduces the amount of water consumed when the activation furnace is working.

[0006] To achieve the above objectives, an industrial production device for activated carbon with rich micropores is provided, comprising a first half-furnace and a second half-furnace. The first half-furnace is installed at one end of the second half-furnace. A water seal trough is fixedly connected to the top of both the first and second half-furnaces. A furnace cover is provided above the water seal trough, with its bottom extending into the water seal trough. Cooling mechanisms are installed on opposite sides of the first and second half-furnaces, communicating with the water seal trough. Branch pipes are fixedly connected to the center of each of the four outer faces of the water seal trough, communicating with the bottom of the water seal trough. The end of the branch pipe furthest from the water seal trough is installed in the cooling mechanism. This device can supply low-temperature water for sealing to the activation furnace during operation, and cool the hot water in the activation furnace after discharge. The cooled water is then reused to seal the activation furnace, preventing the sealing water temperature from becoming too high, reducing the evaporation rate of the sealing water, and thus reducing the water consumption during activation furnace operation.

[0007] According to the aforementioned industrial production equipment for activated carbon with rich micropores, the cooling mechanism consists of a water pump, a water tank, and a water distributor. The water pump, water tank, and water distributor are fixed to the surface of the first or second half-furnace from bottom to top. The inlet of the water pump extends upward into the water tank and is fixedly connected to the water tank. The outlet flange of the water pump is connected to an inlet pipe, and the end of the inlet pipe away from the water pump is fixedly connected to the input end of the water distributor. The surface of the water distributor has four identical outlets, and the four outlets are respectively fixedly connected to four branch pipes on the surface of the water seal trough. Two water filters are installed at the upper end of the water tank, and the bottom of the water filters is connected to the water tank. The upper end of the water filters is fixedly connected to a return water pipe, and the end of the return water pipe away from the water filters is fixedly connected to a drain pipe. The drain pipes are respectively fixedly connected to the middle of both sides of the water seal trough. A drain trough is opened at the upper end of the middle of both sides of the water seal trough, and the water seal trough is connected to the drain pipe through the drain trough. The water pump delivers water from the water tank to the water seal trough sequentially through the inlet pipe, distributor, and branch pipe. Water on the upper surface of the water seal trough enters the drain pipe through the drain channel and returns to the water tank through the return pipe, thus causing the water in the water seal trough to flow.

[0008] According to the industrial production equipment for activated carbon with rich micropores, several heat dissipation fins are fixedly connected to both ends of the water tank, and a cooling fan is fixedly connected to the end of the heat dissipation fins away from the water tank. The heat dissipation fins increase the contact area between the water tank surface and the air, thereby improving the heat dissipation efficiency of the water tank. The cooling fan increases the airflow velocity on the surface of the heat dissipation fins, further improving the heat dissipation efficiency.

[0009] According to the aforementioned industrial production equipment for activated carbon with rich micropores, the water filter consists of a sealing cap, a filter element, and a shell. The shell is fixedly connected to the upper end of the water tank, the filter element is disposed within the shell, and the sealing cap is fixedly connected to the upper end of the shell. Openings are provided in the middle of the sealing cap and the lower middle of the shell, and the shell communicates with the water tank through its bottom opening. A return water pipe is fixedly connected to the upper end of the sealing cap and communicates with the shell through an opening on the sealing cap. The filter element is used to filter the water discharged from the water seal tank, removing dust and impurities. The sealing cap allows the water filter to be opened for easy replacement of the filter element.

[0010] According to the industrial production equipment for activated carbon with rich micropores, the drain pipe gradually slopes downwards from one end of the water seal tank. The angle of inclination of the drain pipe allows water in the water seal tank to flow into the drain pipe and then naturally flow into the return water pipe.

[0011] According to the industrial production equipment for activated carbon with rich micropores, the water tank is made of aluminum, a metal with good thermal conductivity. The aluminum material improves the thermal conductivity of the water tank and shortens the cooling time for the sealing water.

[0012] The above solution has the following advantages: water is supplied to the water seal tank through the water pump and water tank in the cooling mechanism. At the same time, the water above the water seal tank returns to the water tank through the drain pipe and return water pipe and is cooled and recycled. This avoids the water used for sealing on the activation furnace from being continuously heated and evaporated, and reduces the amount of water consumed when the activation furnace is water-sealed.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The end of the branch pipe 15 away from the water seal trough 5 is installed in the cooling mechanism 4.

[0023] The cooling mechanism 4 consists of a water pump 10, a water tank 11, and a water distributor 14. The water pump 10, water tank 11, and water distributor 14 are fixed sequentially from bottom to top on the surface of the first half-furnace 2 or the second half-furnace 3. The inlet of the water pump 10 extends upward into the water tank 11 and is fixedly connected to it. The outlet flange of the water pump 10 is connected to an inlet pipe 13, and the end of the inlet pipe 13 furthest from the water pump 10 is fixedly connected to the input end of the water distributor 14. The surface of the water distributor 14 has four identical outlets, and each of the four outlets is fixedly connected to four branch pipes 15 on the surface of the water seal trough 5. Two water filters 9 are installed at the upper end of the water tank 11. The bottom of the water filter 9 is connected to the water tank 11. The upper end of the water filter 9 is fixedly connected to the return water pipe 7. The end of the return water pipe 7 away from the water filter 9 is fixedly connected to the drain pipe 6. The drain pipe 6 is fixedly connected to the middle of both sides of the water seal trough 5. The upper end of the middle of both sides of the water seal trough 5 is provided with a drain trough 16. The water seal trough 5 is connected to the drain pipe 6 through the drain trough 16. The water pump 10 delivers water from the water tank 11 to the water seal trough 5 through the inlet pipe 13, the water distributor 14 and the branch pipe 15 in sequence. The water on the upper surface of the water seal trough 5 enters the drain pipe 6 through the drain trough 16 and returns to the water tank 11 through the return water pipe 7, thereby making the water in the water seal trough 5 flow.

[0024] Several heat dissipation fins 12 are fixedly connected to both ends of the water tank 11. A cooling fan 8 is fixedly connected to the end of the heat dissipation fins 12 away from the water tank 11. The heat dissipation fins 12 increase the contact area between the surface of the water tank 11 and the air, thereby improving the heat dissipation efficiency of the water tank 11.

[0026] The drain pipe 6 gradually slopes downward from one end of the water seal trough 5. The angle of inclination of the drain pipe 6 allows the water in the water seal trough 5 to flow into the drain pipe 6 and then naturally flow into the return water pipe 7.

[0027] The water tank 11 is made of aluminum, a metal with good thermal conductivity. The aluminum material improves the thermal conductivity of the water tank 11 and shortens the cooling time of the sealed water.

[0028] Working principle: When the activation furnace is in use, the water pump 10 pumps water from the water tank 11 into the water seal tank 5 through the inlet pipe 13, the water distributor 14 and the branch pipe 15. When the water level in the water seal tank 5 reaches the bottom of the drain tank 16, the excess water will enter the drain pipe 6 through the drain tank 16 and then enter the water filter 9 through the return pipe 7 for filtration to remove dust and impurities. The filtered water returns to the water tank 11. The heat dissipation fins 12, together with the heat dissipation fan 8, dissipate heat from the surface of the water tank 11, thereby cooling the water in the water tank 11 and recycling it.

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.
