[0040] Reference Figure 1 and Figure 2 The activated carbon regeneration system 1 includes three groups of activated carbon regeneration cabinets 101 arranged equidistantly (the specific number of groups of activated carbon regeneration cabinets 101 is determined according to actual conditions, and this application does not limit it, and only provides one preferred implementation mode), wherein a plurality of waste activated carbon bins 102 and catalyst loading bins 103 are arranged inside the three groups of activated carbon regeneration cabinets 101, wherein the catalyst loading bin 103 is located above the waste activated carbon bin 102, and the air outlet end of the regeneration air supply system 3 is connected to the bottom of the activated carbon regeneration cabinet 101.

[0041] It should be noted that the cabinet body of the activated carbon regeneration cabinet 101 is made of stainless steel, and the non-opening side is wrapped with thermal insulation cotton. The waste activated carbon bin 102 and the catalyst loading bin 103 adopt drawer-type bin bodies, each bin body can be opened independently, and rubber gaskets are provided at the openings to ensure the air tightness of the equipment. The ratio of the number of waste activated carbon bins 102 to the number of catalyst loading bins 103 is 3:1. The waste activated carbon bin 102 is at the bottom. The waste activated carbon bin 102 is filled with adsorption saturated waste activated carbon, and the catalyst loading bin 103 is filled with square ceramic skeleton precious metal catalyst fillers.

[0042] Reference Figure 1 and Figure 2 The flue gas collection system 2 includes a flue gas collecting chamber 201 connected to the top of the activated carbon regeneration cabinet 101, wherein the flue gas collecting chamber 201 is connected to the flue gas main pipe 203 through a flue gas branch pipe 202, and the other end of the flue gas main pipe 203 is connected to the bottom of the absorption chamber 601. A flue gas heat exchange module 8 is provided directly below the activated carbon regeneration cabinet 101; at the same time, a condensate drain valve 204 and a vacuum breaker 205 are provided on the flue gas branch pipe 202 and at the rear end of the flue gas heat exchange module 8.

[0043] It should be noted that the flue gas collection system 2 is located at the top, side and bottom of the activated carbon regeneration cabinet 101, and includes a flue gas collection chamber 201 and a flue gas delivery pipe (including a flue gas branch pipe 202 and a flue gas main pipe 203). The pipe before the flue gas heat exchange module 8 is made of stainless steel pipe wrapped with insulation cotton, and the pipe after the flue gas heat exchange module 8 is made of PP pipe without insulation.

[0044] Furthermore, the flue gas collection system 2 includes a flue gas collecting chamber 201, a flue gas branch pipe 202, and a flue gas main pipe 203. The flue gas is collected by the flue gas collecting chamber 201 and the flue gas branch pipe 202 connected to the top of the activated carbon regeneration cabinet 101, and the flue gas is transported through the flue gas main pipe 203 surrounding the top and sides of the equipment. The flue gas collection system 2 is first connected to the flue gas heat exchange module 8 at the bottom of the activated carbon regeneration cabinet 101 and then transports the flue gas to the terminal absorption system 6, and is discharged into the atmosphere after absorption and cooling. The pipeline at the bottom of the equipment after the flue gas heat exchange module 8 is set with a slope of 1%, and a condensate drain valve 204 is set at the lowest point of the pipeline. The valve is opened to discharge condensate after each regeneration, and the condensate is discharged to the factory sewage treatment. A vacuum breaker 205 (such as Figure 2 As shown), prevent negative pressure suction from drawing the absorption liquid into the equipment.

[0045] Since the flue gas heat exchange module 8 is arranged directly below the activated carbon regeneration cabinet 101, the high-temperature flue gas duct (flue gas main pipe 203) and the regeneration air duct (regeneration air supply pipe 302) are arranged vertically, and the flue gas exchanges heat with the regeneration air through the heat exchange fins of the heat exchange pipe. After heat exchange, the regeneration air enters the regeneration air distribution chamber 303, and enters the waste activated carbon bin 102 at the bottom of the activated carbon regeneration cabinet 101 after balancing the air flow and temperature.

[0046] Reference Figure 3 and Figure 4 The regeneration air supply system 3 includes a regeneration air supply duct 302, wherein the air inlet end of the regeneration air supply duct 302 is provided with a regeneration air inlet louver 301, and the air outlet end of the regeneration air supply duct 302 is connected to the activated carbon regeneration cabinet 101 through a regeneration air distribution chamber 303; a variable frequency fan 5 is also connected in the middle of the regeneration air supply duct 302, wherein the variable frequency fan 5 is arranged on the mobile transport platform.

[0047] It should be noted that the regeneration air supply system 3 includes an air inlet (or air inlet end), a regeneration air supply pipe 302, and a regeneration air distribution chamber 303. The air inlet is arranged on the side and is equipped with a rectifying louver 301, and the fan is a variable frequency fan; the regeneration air supply pipe 302 before the regeneration air heating module 4 adopts a PP pipe without insulation, and the pipe after the regeneration air heating module 4 adopts a stainless steel pipe with external insulation cotton; the regeneration air distribution chamber 303 is located between the flue gas heat exchange module 8 and the activated carbon regeneration cabinet 101, and is used to balance the regeneration air temperature and flow. A temperature sensor is arranged in the air distribution chamber 3, and the signal is transmitted to the PLC electric control cabinet 7.

[0048] Reference Figure 3 and Figure 4The regeneration air heating module 4 includes an electric heater module 401 and an electric heating controller 402, wherein the electric heater module 401 is installed in the regeneration air supply duct 302, and the electric heating controller 402 is arranged on the mobile transport platform and is electrically connected to the electric heater module 401. The heating method adopts electric heating, and the heating power is controlled by the PLC electric control cabinet 701.

[0049] It should be noted that the regeneration air heating module 4 is located at the rear end of the fan 5 and before the flue gas heat exchange module 8. The heating method adopts electric heating, and the electric heating power is automatically adjusted according to the feedback data of the temperature sensor in the regeneration air distribution chamber 303. The equipment starts to heat the regeneration air to the reaction temperature. After the reaction starts, VOCs decompose and release heat. After the flue gas and the regeneration air exchange heat, the regeneration air temperature is further increased. At this time, the electric heating power is reduced to make full use of the flue gas temperature. When the reaction weakens in the later stage and the regeneration air temperature decreases, the electric heating power is increased to maintain the reaction until the regeneration process ends.

[0050] Reference Figure 1 and Figure 2 The terminal absorption system 6 is located at the end of the smoke collection system 2, and comprises an air distribution hole plate 606, an absorption chamber 601, a chimney 602, a rain cap 603, a water supply valve 604, and an air discharge valve 605. The air distribution hole plate 606 is provided at the connection between the bottom of the absorption chamber 601 and the smoke collection system 2, and the air discharge valve 605 is provided on one side of the bottom of the absorption chamber 601. The top of the absorption chamber 601 is connected to the chimney 602, wherein the top of the chimney 602 is provided with a rain cap 603, and the top side of the absorption chamber 601 is also provided with a water supply valve 604;

[0051] It should be noted that the air hole plate 606 decomposes the flue gas into large bubbles that enter the absorption chamber 601. The main components of VOCs flue gas in the lithium battery workshop are cyclic carbonates and chain carbonates. After high-temperature catalytic decomposition, the decomposition products are carbon dioxide and water. Therefore, water can be used as the absorption liquid. The aqueous solution and the activated carbon powder that can intercept the blown off during the regeneration process can also cool and condense the cyclic carbonates and chain carbonates that are not completely decomposed in the flue gas on the water surface. The flue gas after absorption is discharged to the atmosphere through the chimney 602.

[0052] After the regeneration of the waste activated carbon is completed, the liquid in the absorption chamber 601 is emptied through the drain valve 605 and discharged to the sewage treatment facility in the factory area; before the regeneration of the waste activated carbon begins, the absorption liquid is replenished to the specified liquid level through the water replenishment valve 604. The absorption chamber 601 is equipped with a liquid level and temperature sensor, and the signal is transmitted to the PLC electric control cabinet 701. When the liquid level and temperature are abnormal, an alarm is issued to remind the staff to deal with it.

[0053] Reference Figure 1 and Figure 2The PLC electric control cabinet 7 is set on one side of the operation surface, and the control panel of the electric control cabinet faces the operation surface. It receives sensor signals from various parts of the equipment system, and feedbacks and adjusts the air volume of the variable frequency fan and the power of the electric heater. The panel displays the equipment operation status and sensor data of various parts of the system.

[0054] The specific operating principles of this application are as follows:

[0055] First, the adsorption saturated waste activated carbon is evenly filled in the waste activated carbon bin 102, and the equipment is started through the PLC electric control cabinet 7, the frequency conversion fan 5 and the electric heating controller 402 are started, and the air is introduced into the frequency conversion fan 5 through the regeneration air intake louver 301, and is heated to the reaction temperature by the electric heater module 401 after being pressurized, and then transported to the regeneration air distribution chamber 303 by the regeneration air supply pipe 302, and the regeneration hot air is evenly distributed to the waste activated carbon bin 102; after the regeneration hot air enters the waste activated carbon bin 102, the VOCs in the saturated waste activated carbon are blown off to form concentrated exhaust gas, and the concentrated exhaust gas continues to enter the catalyst filling bin 103, and the VOCs undergo an exothermic decomposition reaction under the combined action of the catalyst and temperature, decomposing into carbon dioxide and water to form high-temperature flue gas.

[0056] After being collected by the flue gas collecting chamber 201, the high-temperature flue gas enters the flue gas main pipe 203 through the flue gas branch pipe 202. The high-temperature flue gas is transported from the flue gas main pipe 203 to the flue gas heat exchange module 8. The high-temperature flue gas duct and the regeneration air duct in the flue gas heat exchange module are arranged vertically. The high-temperature flue gas enters the downstream system after heat exchange. After the regeneration air is heated by heat exchange, it enters the regeneration air distribution chamber 303. The temperature sensor in the air distribution chamber is linked to the electric heating controller 402 to reduce the heating power and make full use of the flue gas temperature. The high-temperature flue gas contains water vapor, which is condensed into liquid water after heat exchange and discharged by the condensate drain valve 204 at the end of regeneration;

[0057] The flue gas after heat exchange enters the air distribution plate 606, and the gas decomposes into bubbles and enters the absorption chamber 601. The flue gas after absorption is discharged to the atmosphere through the chimney 602. After the regeneration of the waste activated carbon is completed, the liquid in the absorption chamber is discharged to the factory sewage treatment facility through the drain valve 605; before the regeneration of the waste activated carbon begins, the absorption liquid is replenished to the specified liquid level through the water replenishment valve 604. The absorption chamber 601 is equipped with a liquid level and temperature sensor, and the signal is transmitted to the PLC electric control cabinet 7. When the liquid level and temperature are abnormal, an alarm is issued to remind the staff to deal with it;

[0058] A vacuum breaker 205 is provided at the hump of the flue gas main pipe 203 conveying gas to the air distribution hole plate 606 to prevent the negative pressure of the pipeline from sucking the liquid in the absorption chamber 601 into the system when the machine is shut down.
