Description

Technical Field

[0001] The present invention belongs to the field of biochar carbonization, and specifically relates to a continuous carbonization and activation furnace for biochar and its usage method. Background Art

[0002] Biochar is a refractory, stable, highly aromatic, carbon-rich solid substance produced by slow pyrolysis of biological residues under anoxic conditions at high temperature; Activated carbon activation is to make the pore structure of activated carbon more developed through physical methods (such as high-temperature steam treatment) or chemical methods (such as treatment with an activator), thereby improving its adsorption capacity.

[0003] Traditional carbonization furnaces usually put raw materials into them, then turn on the heating system to heat and carbonize them, and then turn off the heating system. After waiting for the finished product to cool for a period of time, the finished product is taken out. The entire work process has many steps, seriously affecting production efficiency.

[0004] Therefore, the present invention provides a continuous carbonization and activation furnace for biochar and its usage method. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A continuous carbonization and activation furnace for biochar of the present invention includes a carbonization furnace. A heating platform is fixedly connected to the bottom of the carbonization furnace, and an exhaust valve I is fixedly connected to the top of the carbonization furnace. A moving track is arranged inside the carbonization furnace. The moving track consists of two spiral tracks. The middle parts of the two spiral tracks are fixedly connected by a central track. A rectangular track is fixedly connected to the outside of the two spiral tracks. An activation box is installed outside the rectangular track. A plurality of support platforms are slidably clamped above the moving track. The plurality of support platforms are connected by a series chain. A driving motor for driving the series chain to move is fixedly connected to the bottom of the rectangular track. A feeding cabinet is arranged on the top of the support platform, and an exhaust valve I is fixedly connected to the top of the carbonization furnace; Put the biochar raw materials to be processed into the feeding cabinet. Drive the series chain to move through the driving motor. Drive the support platform and the feeding cabinet to move on the moving track through the series chain. The moving track, the central track and the rectangular track form a closed circular track. The whole series chain moves in the closed track, so as to drive multiple support platforms and feeding cabinets to move in a cycle. When the feeding cabinet moves to the rectangular track exposed outside, it is used to feed raw materials and recycle the finished biochar that has been carbonized. When the feeding cabinet moves into the carbonization furnace, the heating platform at the bottom of the carbonization furnace table can use electric heating or other methods to heat up the carbonization furnace. Thus, the raw materials moved into the carbonization furnace can be subjected to high-temperature water treatment, enabling the raw materials to be steadily carbonized. During the continuous movement of the series chain, continuously feed biochar raw materials into the empty feeding cabinet, and let the new feeding cabinet enter the carbonization furnace. According to different raw materials, adjust the driving speed of the driving motor, and then the carbonization time of the feeding cabinet in the carbonization furnace can be controlled. It can make the feeding cabinet just complete the carbonization time when it exits the carbonization furnace. A temperature measurement module is arranged inside the carbonization furnace to detect the temperature inside the carbonization furnace. At the same time, the exhaust valve 1 can control its own exhaust according to the measured temperature of the temperature measurement module, because when the water vapor is too high, it will cause the temperature inside the carbonization furnace to exceed the predetermined temperature. Then the raw materials and the feeding cabinet in the high-temperature state enter the activation box for activation treatment. The activation box can inject activation gases such as carbon dioxide or air into the feeding cabinet. The activation gas reacts with the carbonized material to form a pore structure and improve the adsorption capacity of the activated carbon. Through this method, continuous carbonization and activation treatment of biochar raw materials are realized. At the same time, the spiral moving track is set, so that the carbonization furnace first enters from the edge, then slowly moves to the central position, and finally transfers out from the edge. The temperature in the central position is relatively high, and the temperature on both sides is relatively low. In this way, the raw materials can be preheated first, and then heated and carbonized intensively at the central position. During the outward transfer process, the temperature is appropriately reduced to finally obtain high-quality carbonized products. This continuous working method greatly improves the production efficiency, can realize uninterrupted production. Compared with the traditional carbonization furnace, the continuous carbonization process can save more steps and effectively improve the production efficiency.

The sealing plates are grabbed by the hydraulic rod. A connecting valve is fixedly connected to the bottom of the hydraulic rod for grabbing and fixing the sealing plates. Then the hydraulic rod drives the sealing plates to move above the feeding cabinet. As the sealing plates approach the feeding cabinet, the locking arms will contact the latch blocks, thereby fixing the feeding cabinet and the sealing plates. Then the hydraulic rod can drive the feeding cabinet to move; Q2: An air pump is installed on the top of the sealing plate, which is used to continuously pump the air in the activation tank into the feeding cabinet.

When the feeding cabinet 5 moves to the rectangular track 19 exposed outside, it is used to feed the raw materials and recycle the finished biochar that has been carbonized. When the feeding cabinet 5 moves into the carbonization furnace 1, the heating platform 7 at the bottom of the carbonization furnace platform 1 can use electric heating or other methods to heat up the carbonization furnace 1. Thus, the raw materials moved into the carbonization furnace 1 can be subjected to high-temperature water treatment, enabling the raw materials to be steadily carbonized. During the continuous movement of the series chain 13, continuously feed the biochar raw materials into the empty feeding cabinet 5, so that the new feeding cabinet 5 enters the carbonization furnace 1. According to different raw materials, adjust the driving speed of the drive motor 6, and the carbonization time of the feeding cabinet 5 in the carbonization furnace 1 can be controlled.

The activation box 3 can inject activation gases such as carbon dioxide or air into the feeding cabinet 5. The activation gas reacts with the carbonized material to form a pore structure and improve the adsorption capacity of the activated carbon. Through this method, the continuous carbonization and activation treatment of the biochar raw materials are realized.

9. A method for using a biochar continuous carbonization and activation furnace, characterized in that: The method is applicable to any one of the biochar continuous carbonization activation furnaces described in claims 1 to 8 above, and the method is specifically: S1: The biochar raw materials to be processed are placed in the delivery cabinet, and the series chain is driven by the driving motor to move, and the series chain drives the support table and the delivery cabinet to move on the moving rail. The moving rail, the center rail and the rectangular rail form a closed circular track. The entire series chain moves in the closed track, thereby driving multiple support tables and delivery cabinets to move in a cycle; S2: When the delivery cabinet is moved to the carbonization furnace, the heating table at the bottom of the carbonization furnace table uses electric heating and other methods to heat the carbonization furnace, so that the raw materials moved into the carbonization furnace can be subjected to high-temperature dehydration treatment, so that the raw materials can be stably carbonized; S3: During the continuous movement of the series chain, biochar raw materials are continuously put into the empty delivery cabinet, so that the new delivery cabinet can enter the carbonization furnace. According to different raw materials, the driving speed of the driving motor is adjusted to control the carbonization time of the delivery cabinet in the carbonization furnace; the delivery cabinet can be made to complete the time required for carbonization when it leaves the carbonization furnace, and then the raw materials and delivery cabinet in a high temperature state enter the activation box for activation treatment.

10. The method for using the biochar continuous carbonization and activation furnace according to claim 9, characterized in that: The activation treatment method of the activation box in step S3 is specifically as follows: Q1: A sealing plate is stacked on one side of the activation box. The sealing plate is picked up by a hydraulic rod. A connecting valve is fixed to the bottom of the hydraulic rod to grab and fix the sealing plate. Then the hydraulic rod drives the sealing plate to move to the top of the delivery cabinet. As the sealing plate approaches the delivery cabinet, the locking arm will contact the card block, thereby fixing the delivery cabinet and the sealing plate. Then the hydraulic rod can drive the delivery cabinet to move; Q2: An air pump is installed on the top of the sealing plate to continuously draw the air in the activation box into the delivery cabinet. When the hydraulic rod is released from the sealing plate, the air pump starts to work, and the outside of the activation box is connected to the pipeline to continuously inject the activation gas into the activation box. The gas injected by the air pump is eventually discharged from the exhaust hole at the bottom to ensure that the gas contacts all finished products, thereby ensuring the activation process of the finished products.
