Description
Technical Field
[0001] The invention relates to the technical field of activated carbon processing, and in particular to high-temperature activation equipment for producing activated carbon fiber felt. Background Art
[0002] Activated carbon fiber felt is a fiber material doped with activated carbon. It has strong adaptability, good conductivity and chemical stability. It is widely used in air purification, industry and military fields.
[0003] Rotary kiln refers to a rotary calcining kiln (commonly known as a rotary kiln), which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the different materials they process.
[0004] The high-temperature activation of activated carbon is generally carried out in a rotary kiln. The raw materials for making activated carbon are added to the tail of the kiln by a feeder and slowly move to the head of the kiln with the help of the inclination and rotation of the kiln body. The fuel chamber is set at the head of the kiln. The hot gas generated by the combustion of coal gas or crude oil directly enters the kiln body and moves from the head of the kiln to the tail of the kiln. The high-temperature activation of activated carbon is carried out at 700 to 1000 degrees Celsius. An oxidant is used to remove a small amount of hydrocarbons left during carbonization, and the original pores are expanded and penetrated to make the activated carbon a good porous structure material. The activated activated carbon raw materials and fiber felt are compressed and mixed to make activated carbon fiber felt.
[0005] When activated carbon is activated at high temperature, the activated carbon raw material is usually directly added into the rotary kiln through the hopper. The activated carbon in the rotary kiln is unevenly distributed, which affects the high-temperature activation effect of the activated carbon. A large amount of high-temperature flue gas will be generated during the high-temperature activation of activated carbon. If the high-temperature flue gas can be used to preheat the activated carbon raw material, the efficiency of high-temperature activation of activated carbon can be greatly improved.

Under the obstruction of the inner sealing plate 1807, the high-temperature flue gas moves from the inner flow channel 1806 to the purification filter cartridge 1808, and the high-temperature flue gas is initially purified by the purification filter cartridge 1808. After a purification step, the high-temperature flue gas enters the outer flow channel 1809, and contacts the purification filter cartridge 1810 through the barrier of the outer sealing plate 1811. The high-temperature flue gas is further purified by the purification filter cartridge 1810, and the purified high-temperature flue gas enters the outlet pipe 1813 from the inner flow channel 1812, and then enters the interior of the preheating barrel 1 through the nozzle 1814, heats the interior of the preheating barrel 1, realizes the utilization of waste heat, and purifies the flue gas, which is energy-saving and environmentally friendly.
[0041] Working principle: The activated carbon raw material falls on the spiral feeding hopper 202 through the feeding port of the preheating barrel 1. The spiral feeding hopper 202 adopts a spiral structure. The activated carbon raw material spirally enters the rotary kiln 7. During the feeding process, the motor 207 is started to move the movable rod 201 upward. When the toothless part of the toothless gear 208 rotates to the side of the rack 209, the movable rod 201 moves downward. With the elastic effect of the vibration spring 204, the activated carbon raw material in the spiral feeding hopper 202 vibrates to avoid blockage caused by the accumulation of activated carbon raw materials during the feeding process, thereby ensuring the feeding efficiency. During the feeding process, the motor 2 302 is driven counterclockwise and clockwise to rotate the screw rod 303, and the combing rake claw 306 reciprocates along the inside of the spiral feeding hopper 202. The combing rake claw 306 combs the activated carbon raw material so that the activated carbon raw material is evenly laid on the inner wall of the bottom surface of the spiral feeding hopper 202, and is further combed by the inner and outer shaving plates 307 and 309. The activated carbon raw material slides neatly along the inner wall of the bottom surface of the spiral feeding hopper 202, so that the activated carbon raw material is evenly heated, and the preheating effect of the activated carbon raw material is good. The preheated activated carbon raw material enters the rotary kiln 7, and the activated carbon raw material is high-temperature activated inside the rotary kiln 7. During the high-temperature activation treatment, the high-temperature flue gas generated enters the smoke exhaust box 5, and the carbon ash contained in the high-temperature flue gas is filtered through the inner filter cartridge 8 and the outer filter cartridge 11 to avoid the carbon ash in the high-temperature flue gas from being directly discharged to pollute the environment, thereby completing the high-temperature activation of the activated carbon. After warm activation, start motor three 1201, and the fixed bracket 1202 drives the outer filter cartridge 11 to rotate, so that the inner wall of the outer filter cartridge 11 contacts the surface of the outer cleaning brush 10 at different positions, and the carbon ash condensed on the inner wall of the outer filter cartridge 11 is scraped off. When the screw rod two 1203 rotates, the mounting bracket 1204 slides along the surface of the screw rod two 1203, and the annular cleaning brush 1205 moves along the inner wall of the inner filter cartridge 8 toward the side of motor three 1201, and the carbon ash on the inner wall of the inner filter cartridge 8 is scraped off. The scraped carbon ash falls on the surface of the filter screen plate 14, and the circulation pump 15 is started. The circulation pump 15 draws water out of the water storage tank 13 and sprays it out through the water outlet pipe 16 from the atomizing nozzle 17. The water contacts the carbon ash during the spraying process, so that the carbon ash falls on the filter screen plate 14 to prevent the carbon ash from contacting with the high-temperature flue gas. They enter the preheating barrel 1 together, and the vacuum pump 1801 is started during the process of cleaning the carbon ash. The vacuum pump 1801 generates suction from the outer filter cartridge 11 to the side of the air inlet box 1803 through the vacuum pipe 1802, and the carbon ash on the inner wall of the outer filter cartridge 11 is sucked out and falls on the filter mesh plate 14. At the same time, the high-temperature flue gas enters the flue gas purification cartridge 1805. Under the obstruction of the inner sealing plate 1807, the high-temperature flue gas moves from the inner flow channel 1806 to the purification filter cartridge 1 1808, and the high-temperature flue gas is preliminarily purified by the purification filter cartridge 1 1808. Then the high-temperature flue gas enters the outer flow channel 1809, and contacts with the purification filter cartridge 2 1810 through the obstruction of the outer sealing plate 1811, and the high-temperature flue gas is further purified by the purification filter cartridge 2 1810.The purified high-temperature flue gas enters the outlet pipe 1813 through the second inner flow channel 1812, and then enters the interior of the preheating barrel 1 through the nozzle 1814, heating the interior of the preheating barrel 1, realizing the utilization of waste heat, and purifying the flue gas, which is energy-saving and environmentally friendly.
