[0002] The activated carbon carbonization process is to put the formed strips into the carbonization furnace, and then drive out the moisture and most of the volatiles in the formed strips to form a carbonized material with a certain skeleton strength. In the traditional process, the flue gas containing volatile substances generated during the carbonization of the formed strips in the carbonization furnace is pumped into the incinerator for incineration, and the large amount of heat generated during the incineration process is used to heat the boiler to produce steam, thereby achieving the purpose of waste heat utilization, but the waste heat cannot be fully utilized, and part of the waste heat is discharged directly or indirectly. At the same time, in order to ensure the furnace temperature during operation, a certain amount of fuel must be burned at the burner as the heat source of the carbonization furnace (coal, coal gas, natural gas, etc.), resulting in increased production costs.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-7A novel self-heating balanced carbonization furnace comprises a burner combustion chamber 1, a furnace body 3, a flue 7, an incinerator 8 and a waste heat boiler 10. The burner combustion chamber 1 is fixedly connected to one side of the furnace body 3, and a hopper 5 is connected to the other side of the furnace body 3. An arc-shaped baffle 4 is provided on the side where the hopper 5 is connected to the furnace body 3. One side of the bottom surface of the furnace body 3 is connected to the flue 7, and the end of the flue 7 is connected to the incinerator 8. The incinerator 8 is connected to the waste heat boiler 10. One side of the waste heat boiler 10 is connected to an induced draft fan 11, and the induced draft fan 11 is connected to a chimney 12. A steam jet pump 9 is provided on the top of the incinerator 8, and the input end of the steam jet pump 9 is connected to the incinerator 8, and the output end of the steam jet pump 9 is connected to the burner combustion chamber 1. The waste heat boiler 10 is connected to the input end of the steam jet pump 9 through a steam pipe 13, and a steam regulating valve 14 is provided on the steam pipe 13. In the initial state of carbonization, external energy is required to ignite the burner combustion chamber 1. After the furnace body 3 reaches the carbonization temperature, the raw materials are added from the hopper 5, and the materials enter the tail of the carbonization furnace from the inlet 6 and are discharged from the discharge trough 2. The material is slowly carbonized in the furnace body 3, and a large amount of volatile combustible flue gas will be generated at this time. Since the induced draft fan 11 at the end of the equipment continues to work, these combustible flue gases are sucked into the flue 7 from the tail, and then enter the incinerator 8, where they are fully burned to become clean tail gas, and a large amount of heat energy is generated at the same time. Part of this heat energy is sucked into the waste heat boiler 10 to generate steam for production use, and part of the heat energy is blown into the burner combustion chamber by the steam jet pump 9 to provide a continuous heat source for the furnace body 3. The amount of heat obtained by the furnace body 3 can be controlled by adjusting the steam jet pump airflow through the steam regulating valve 14. The amount of induced air of the induced draft fan 11 at the end of the equipment matches the amount of airflow generated by the steam jet pump 9. Through regulation, the heat balance of the carbonization furnace can be achieved.

[0020] Through the use of this equipment technology, the fuel usage of the carbonization furnace can be reduced, which can save fuel costs; at the same time, the temperature of the carbonization furnace can be stably controlled, and the quality of the carbonized material can be improved.

By rotating the adjusting stud 23, the angle of the partition 15 can be adjusted, thereby adjusting the discharge speed of the material inside the furnace body 3.

[0022] A cleaning structure is provided above the interior of the furnace body 3, and the cleaning structure includes a reciprocating screw 24, which is rotatably mounted on the top wall of the interior of the furnace body 3, and a first bevel gear 25 is fixedly connected to one end of the reciprocating screw 24.

The second bevel gear 26 is meshed with the first bevel gear 25. A U-shaped mounting bracket 28 is screwed to the reciprocating screw 24, and a third bevel gear is sleeved on the reciprocating screw 24 between the mounting brackets 28. Wheel 34, a key strip 35 is fixedly connected to the inner wall of the third bevel gear 34, a key groove 36 is opened on the outer wall of the reciprocating screw 24, the key strip 35 is slidably connected in the key groove 36, a slide tube 29 is rotatably installed at the bottom of the mounting frame 28, a fourth bevel gear 30 is fixedly connected to the top of the slide tube 29, the fourth bevel gear 30 is meshed with the third bevel gear 34, a square plug rod 37 is inserted at the bottom of the slide tube 29, the bottom end of the plug rod 37 is connected to the brush 32 through a universal coupling 31, and a spring 33 is sleeved on the plug rod 37. Start the motor 27, and the motor 27 drives the second bevel gear 26 to rotate. The rotation of the second bevel gear 26 drives the first bevel gear 25 to rotate. The first bevel gear 25 drives the reciprocating screw 24 to rotate. When the reciprocating screw 24 rotates, it drives the mounting frame 28 to move horizontally inside the furnace body 3, thereby driving the brush 32 to move inside the furnace body 3. During the movement, the brush 32 will clean the upper surface of the partition 15 to prevent material from remaining on the surface of the partition 15. During the movement of the mounting frame 28, the rotation of the reciprocating screw 24 will also drive the third bevel gear 34 to rotate. The rotation of the third bevel gear 34 drives the fourth bevel gear 30 to rotate. The rotation of the fourth bevel gear 30 drives the slide tube 29 to rotate. The slide tube 29 drives the insertion rod 37. The rotation of the insertion rod 37 drives the brush 32 to rotate through the universal coupling 31.
