Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a kind of waste gas adsorption device for special resin production, including main adsorption box 1, main adsorption box 1 side is provided with spare adsorption box 11, main adsorption box 1 and spare adsorption box 11 top are all provided with opening, main adsorption box 1 and spare adsorption box 11 inside are installed with activated carbon 8, activated carbon 8 is honeycomb structure, with dense pore, for adsorbing harmful substance in waste gas, its regular shape is convenient in main adsorption box 1 It is arranged and installed, and bottom is all provided with heating assembly, main adsorption box 1 and spare adsorption box 11 between connection have Y-shaped pipe 13, as waste gas shunt passage, main adsorption box 1 and spare adsorption box 11 side are communicated with connecting pipe A 4 and connecting pipe B 12 respectively, two outlet pipes of Y-shaped pipe 13 are communicated with connecting pipe A 4 and connecting pipe B 12 respectively, connecting pipe A 4, connecting pipe B 12 and Y-shaped pipe 13 connection place are fixedly connected with control assembly 5, and with Y-shaped pipe 13 cooperation realizes the flexible distribution of waste gas between main adsorption box 1 and spare adsorption box 11. Please refer to Figure 4 Control assembly 5 includes valve body 51, pin hole is symmetrically provided in the inner wall of valve body 51, valve rod 52 is installed between pin hole, valve plate 56 is fixedly connected on the outer surface of valve rod 52, valve plate 56 is in rotating contact with the inner side of valve body 51, pin 53 is sleeved on the both ends of valve rod 52, handle 55 is connected on one end of valve rod 52, self-locking nut 54 is threadedly connected between valve rod 52 and handle 55, handle 55 is firmly fixed on valve rod 52 by the way of thread connection, to prevent handle 55 from loosening or accidentally falling off during use.

[0024] In implementation, the exhaust gas first enters through the inlet of the Y-shaped pipe 13. In the initial state, the valve plate 56 of the connecting pipe A4 is in the open state and the valve plate 56 of the connecting pipe B12 is in the closed state by rotating the handle 55 to adjust the valve rod 52 to rotate the valve plate 56. The exhaust gas enters the main adsorption tank 1 through the connecting pipe A4 and fully contacts the activated carbon 8 inside the main adsorption tank 1. The activated carbon 8 uses its porous structure to adsorb harmful components in the exhaust gas. When the activated carbon 8 inside the main adsorption tank 1 is saturated and needs to be desorbed, the valve plate 56 of the connecting pipe A4 is closed and the valve plate 56 of the connecting pipe B12 is opened, so that the exhaust gas enters the standby adsorption tank 11 through the connecting pipe B12 for adsorption treatment. The saturated activated carbon 8 is desorbed by opening the heating assembly to uniformly transfer heat to the activated carbon 8. As the temperature of the activated carbon 8 rises, the organic molecules adsorbed on the surface and in the pores of the activated carbon 8 are separated from the activated carbon 8 due to the rise in temperature and are discharged from the opening at the top of the main adsorption tank 1.

[0025] Referring to Figures 1-2 As shown, the main adsorption tank 1 and the standby adsorption tank 11 are communicated with the exhaust pipe 7 away from the side of the Y-shaped pipe 13, which is used to discharge the exhaust gas after adsorption treatment. The main adsorption tank 1 and the standby adsorption tank 11 are fixedly connected with the exhaust pipe 2 at the top opening. The butterfly valve is arranged in the exhaust pipe 2 to control the opening and closing of the exhaust pipe 2 without affecting the adsorption of the exhaust gas.

[0026] Referring to Figures 2-3 The bottom of the main adsorption tank 1 is open. The heating assembly includes the electromagnetic valve 9, which is fixedly connected inside the opening of the main adsorption tank 1. The electromagnetic valve 9 is provided with the hot air generator 6 at the bottom. The hot air generator 6 is composed of a blower and a heater. The blower sucks air into the heater to heat the air to become hot air by converting electrical energy into heat energy. When the activated carbon 8 is in normal use, the electromagnetic valve 9 is controlled to be closed to avoid the exhaust gas entering the hot air generator 6 and affecting the adsorption effect of the exhaust gas.

[0027] Referring to Figure 1 Ventilation openings 15 are provided on both sides of the main adsorption tank 1 and the standby adsorption tank 11. The connecting pipes A4 and B12 are installed inside the ventilation openings 15. The ventilation openings 15 enable these pipes to communicate with the internal space of the main adsorption tank 1 and the standby adsorption tank 11, so that the exhaust gas can smoothly enter and exit. The top of the main adsorption tank 1 and the standby adsorption tank 11 is rectangular prism-shaped. In the desorption process, the gas flows upward. The top of the rectangular prism-shaped can guide the gas to converge in the direction of the exhaust pipe 2, reducing the retention of the gas at the top.

[0028] Referring to Figure 1 and Figure 3The inlet pipe of the Y-shaped pipe 13 is clamped with the filter screen 14 through the clamping groove, which can filter out part of the impurity particles in the exhaust gas, reduce the possibility of blocking the pores of the activated carbon 8, and avoid the influence of impurities on the adsorption effect of the activated carbon 8.

[0029] Referring to Figure 5 The main adsorption box 1 is fixedly connected with the electric heating plate 3 on the inner wall of both sides, and the electric heating plate 3 is connected with the heat conduction plate 10 on the opposite side. The heat conduction plate 10 is made of aluminum alloy, which has good heat conduction performance. The heat can be quickly and uniformly transferred from the electric heating plate 3 to the activated carbon 8, so as to avoid the phenomenon of local overheating. The inner side of the heat conduction plate 10 is attached to the activated carbon 8. When the activated carbon 8 needs to be desorbed, the electric heating plate 3 can be used as an auxiliary heating mode, which cooperates with the hot air generator 6 to improve the heating efficiency. The side walls of the main adsorption box 1 and the standby adsorption box 11 are rotatably connected with the rotating shaft 16 through the bearing. The rotating shaft 16 is in interference fit with the side plate 20. The electric heating plate 3 is fixedly connected to the inner side of the side plate 20, which is convenient for the operator to maintain, inspect or replace the activated carbon 8 in the adsorption box, or to carry out diversified treatment on the activated carbon 8.

[0030] Referring to Figure 3 One side of the side plate 20 is fixedly connected with the fixed block 19, and the side surface of the fixed block 19 is fixedly connected with the spring clamp 17, which is composed of a spring and a clamp ring. The standby adsorption box 11 is fixedly connected with the clamping block 18 on the side close to the fixed block 19. The clamping block 18 cooperates with the spring clamp 17 to fix the side plate 20. When the side plate 20 is closed, the spring clamp 17 can be clamped on the clamping block 18, and the side plate 20 is fixed on the standby adsorption box 11 by the elastic force of the spring, which prevents the side plate 20 from being accidentally opened during the operation of the standby adsorption box 11, and ensures the sealing and stability of the standby adsorption box 11.

[0031] Working principle: when in use, connect the device to the power supply. The exhaust gas first enters through the inlet pipe of the Y-shaped pipe 13. The filter screen 14 at the inlet pipe can filter out part of the impurity particles in the exhaust gas. In the initial state, the valve plate 56 of the connecting pipe A4 is in the open state, and the valve plate 56 of the connecting pipe B12 is in the closed state by rotating the handle 55 to adjust the valve rod 52 to drive the valve plate 56 to rotate. The exhaust gas enters the main adsorption box 1 through the connecting pipe A4. The exhaust gas is in full contact with the activated carbon 8 in the main adsorption box 1. The activated carbon 8 uses its porous structure to adsorb harmful components in the exhaust gas. The gas after adsorption treatment is discharged from the exhaust pipe 7 on one side of the main adsorption box 1.

[0032] When the main adsorption box 1 needs to be desorbed, the valve plate 56 connected to the pipe A4 is closed to prevent the exhaust gas from continuing to enter the main adsorption box 1, and the valve plate 56 connected to the pipe B12 is opened to allow the exhaust gas to enter the standby adsorption box 11, where it is adsorbed by the activated carbon 8. At the same time, the electromagnetic valve 9 and the hot air generator 6 can be opened, allowing the hot air generated by the hot air generator 6 to enter the main adsorption box 1 and desorb the saturated activated carbon 8. The electric heating plate 3 is turned on, which evenly transfers heat to the activated carbon 8 through the aluminum alloy heat-conducting plate 10. As the temperature of the activated carbon 8 rises, the organic molecules adsorbed on its surface and in its pores are released due to the increase in temperature, and are then removed from the exhaust pipe 2 along with the hot air blown out by the hot air generator 6.

[0033] After desorption is complete, the heating assembly is turned off, and the activated carbon 8 in the main adsorption box 1 is allowed to cool. When it has cooled to an appropriate temperature, the main adsorption box 1 can be switched back to adsorption mode, while the standby adsorption box 11 is operated in desorption mode. This cycle ensures continuous and effective treatment of special resin production exhaust gas, improving work efficiency.

[0034] When the main adsorption box 1 or the standby adsorption box 11 needs to be repaired, the spring clamp 17 is pulled off the clamping block 18, and the side plate 20 is turned to open, making it easy to replace the old activated carbon 8 or to perform various treatments on the activated carbon 8. The spring force fixes the side plate 20 to the standby adsorption box 11, preventing accidental opening of the side plate 20 during operation of the standby adsorption box 11, and ensuring the sealing and stability of the standby adsorption box 11.
