Description

Technical Field

[0001] This utility model relates to the field of volatile gas recovery technology, and in particular to an absorption device for volatile components in the production process of environmentally friendly flame-retardant lubricants. Background Technology

[0002] In the production process of environmentally friendly flame-retardant lubricants, especially in the processes of raw material heating, mixing reaction, and dehydration, volatile organic compounds (VOCs) and other volatile components with odors are inevitably generated. If these gases are directly emitted, they will not only cause environmental pollution and endanger human health, but also lead to the loss of production materials.

[0003] Currently, adsorption, especially activated carbon adsorption beds, is one of the common methods for treating low-concentration, high-volume organic waste gases. The principle is to utilize the large specific surface area and abundant pore structure of activated carbon to capture and enrich the volatiles in the waste gas within a fixed adsorption bed, thereby purifying the emitted gas.

[0004] Chinese utility model patent with announcement number CN221207429U discloses an absorption device for volatile components in the lubricant production process. This device uses a cylindrical processing device to adsorb and recover the volatile components and discharge the purified gas. This device first treats large-scale waste gas directly in the production line. However, this device has low efficiency when desorbing activated carbon and cannot effectively clean up small amounts of sticky dust in the volatile gas. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model discloses an absorption device for volatile components during the production process of an environmentally friendly flame-retardant lubricant.

A second pipe is arranged at the lower end of the adsorption box. An installation frame is slidably arranged on the support frame. A striking plate is slidably arranged on the installation frame. A spring is arranged between the striking plate and the installation frame. A second motor is arranged on the installation frame. A cam is arranged on the output shaft of the second motor. The cam is rotatably connected to the installation frame. The cam is in contact with the striking plate. When the striking plate slides back and forth on the installation frame, it strikes the adsorption boxes.

[0007] Furthermore, it also includes a first pipe, which is connected to multiple adsorption boxes. A valve third is provided between the first pipe, the second pipe and the adsorption boxes.

Detailed Implementation

[0018] refer to Figures 1 to 4 The device shown is an absorption device for volatile components in the production process of an environmentally friendly flame-retardant lubricant. It includes an adsorption box 1 containing activated carbon. The adsorption box 1 adsorbs the volatile gas through the activated carbon. After the adsorption is completed, the gas is discharged through a pipe 2 5. The activated carbon is desorbed through a gas-liquid separator 2 and an inlet box 3. After the desorption is completed, the non-condensable gas is reprocessed to complete the gas recycling process and improve the recovery efficiency.

[0019] refer to Figure 1 , Figure 2 The support frame 14 shown has three sets of adsorption boxes 1. Each adsorption box 1 is filled with activated carbon. The upper end of the adsorption box 1 is connected to pipe 4. After pretreatment, the collected volatile gas is transported to the adsorption box 1 through pipe 4 for adsorption. The lower end of the adsorption box 1 is connected to pipe 5. Pipe 5 is installed on the support frame 14 and is filled with a filter screen. Each connection between pipe 4, pipe 5 and adsorption box 1 is equipped with valve 13. The gas discharge in the adsorption box 1 is controlled by controlling the closing of valve 13. When the adsorption box 1 is needed to adsorb gas, valve 13 at both the upper and lower ends of the adsorption box 1 is opened to connect the adsorption box 1, pipe 4 and pipe 5. The gas enters the adsorption box 1 through pipe 4 and is discharged through pipe 5 after adsorption is completed.

[0020] refer to Figures 1 to 4 The support frame 14 shown has pipes 11 and 12 at its upper and lower ends, respectively. Both pipes 11 and 12 are connected to three adsorption boxes 1 via valves 16. Pipe 11 is located at the upper end of adsorption box 1, and pipe 12 is located at the lower end of adsorption box 1. Valves 16 are installed at the connection points of pipe 15 and multiple adsorption boxes 1. By controlling the closure of pipe 11, pipes 11 and 12 can communicate with adsorption boxes 1.

[0021] refer to Figure 1 , Figure 2The diagram also includes an air intake box 3, on one side of which is an air pump 10. The other end of the air intake box 3 is connected to pipe six 12. A heating element is installed inside the air intake box 3. The air pump 10 draws air into the air intake box 3 and the heating element heats the air. The air is then transported to the adsorption box 1 through pipe six 12. The hot air desorbs the activated carbon in the adsorption box 1. The air carrying the desorbed material then enters pipe five 11 through pipe seven 15.

[0022] refer to Figures 1 to 4 The diagram also includes a gas-liquid separator 2, with a pipe 4 7 installed on the side of the gas-liquid separator 2. A tubular cooler is installed inside the pipe 4 7, which is connected to the pipe 5 11. A pipe 3 6 is installed at the upper end of the gas-liquid separator 2, which is connected to the side of the pipe 1 4. A valve 1 8 is installed between the gas-liquid separator 2 and the pipe 3 6, which controls the connection between the gas-liquid separator 2 and the pipe 3 6. The desorbed gas is discharged into the pipe 4 7 through the pipe 5 11, where the pipe 4 7 cools the gas. The cooled gas-liquid mixture enters the gas-liquid separator 2, and the liquid falls to the bottom of the gas-liquid separator 2. The gas is transported to the pipe 1 4 through the pipe 3 6 at the upper end of the gas-liquid separator 2 for adsorption again.

[0023] A motor 17 is mounted on the support frame 14. A lead screw 18 is mounted on the output shaft of the motor 17 and is rotatably connected to the support frame 14. A mounting frame 19 is slidably mounted on the support frame 14 and is threadedly connected to the lead screw 18. A striking plate 20 is slidably mounted on the mounting frame 19 and is connected to the striking plate 20 by a spring 21. A motor 22 is mounted on the mounting frame 19 and is mounted on the output shaft of the motor 22. The cam 23 is in contact with the striking plate 20. When the motor 22 is started, it drives the cam 23 to rotate, which in turn drives the striking plate 20 to slide on the mounting frame 19. The striking plate 20 slides back and forth on the mounting frame 19 due to the deformation restoring force of the spring 21. The striking plate 20 strikes the adsorption box 1, thereby improving the desorption effect of the activated carbon in the adsorption box 1.

[0024] Working principle: In the initial state, the air pump 10 and all valves are closed. When it is necessary to adsorb volatile gases, select the two sets of adsorption boxes 1 that need to be operated, and open the valves 13 at both ends of the two sets of adsorption boxes 1. At this time, the pipeline 1 4, the adsorption box 1 and the pipeline 2 5 are connected. The volatile gas is pretreated by filtering, dust removal, dehumidification and pre-cooling before being transported into the pipeline 1 4. After the pretreated volatile gas enters the pipeline 1 4, it enters the adsorption box 1. The activated carbon in the adsorption box 1 adsorbs the gas. After the adsorption is completed, it is discharged through the pipeline 2 5. The filter screen set in the pipeline 2 5 filters the gas again.

[0025] If the activated carbon in adsorption box 1 reaches saturation and needs to be desorbed during operation, close valves 313 at both ends of this set of adsorption boxes 1 to prevent volatile gases from re-entering the adsorption box 1 for adsorption. At the same time, open valves 313 at both ends of the idle set of adsorption boxes 1 to replace adsorption boxes 1, so as to avoid affecting the volatile gas processing capacity of this device when desorbing activated carbon.

[0026] When desorbing activated carbon, first open valve 16 at both ends of the adsorption box 1 to be desorbed, and simultaneously open valve 9 and valve 8. At this time, start the air pump 10 and the heating element in the air inlet box 3. The air pump 10 draws air into the air inlet box 3, and the heating element heats the air entering the box. Then, the air pump 10 delivers the heated air to the adsorption box 1 through pipe 12 and pipe 15. The air enters the adsorption box 1 from the bottom and blows off the substances on the activated carbon, which then move with the gas. The gas carrying the desorbed substances is delivered to pipe 7 through pipe 15 and pipe 11. The tubular condenser in pipe 7 is started in advance. The tubular condenser cools and condenses the gas passing through pipe 7. Then, it enters the gas-liquid separator 2 for gas-liquid separation. The liquid is discharged through the bottom of the gas-liquid separator 2, and the non-condensable gas enters pipe 4 through pipe 6 for adsorption again, realizing the cyclic adsorption of volatile gases.

[0027] After the desorption of activated carbon is completed, turn off the air pump 10 and simultaneously close valve 8, valve 9, and air pump 10. At the same time, put the adsorption box 1, which has completed desorption, into idle state for later use.

[0028] While desorbing the activated carbon in the adsorption box 1, motor 17 is started. Motor 17 drives the lead screw 18 to rotate. The lead screw 18 drives the mounting frame 19 to slide on the support frame 14. The position of the mounting frame 19 is adjusted. When the mounting frame 19 drives the striking plate 20 to align with the adsorption box 1, motor 22 is started. Motor 22 drives the cam 23 to rotate. The cam 23 drives the striking plate 20 to slide back and forth on the mounting frame 19. The striking plate 20 strikes the adsorption box 1, improving the desorption efficiency of the activated carbon in the adsorption box 1.
