Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly to a waste gas treatment device for epoxy resin production. Background Art

[0002] A zeolite rotor is a waste gas treatment device based on the adsorption characteristics of zeolite molecular sieves, mainly used for treating waste gas with large air volume and low concentration of volatile organic compounds (VOCs). Its core principle is to concentrate low-concentration waste gas into high-concentration waste gas through the cyclic process of adsorption, desorption, and cooling, reducing the energy consumption and cost of subsequent treatment equipment;

[0003] When the zeolite rotor rotates to the desorption area during use, the impurities on the surface of the rotor are blocked outside the desorption area by the partition frame in the adsorption area and cannot enter the desorption area for desorption treatment, resulting in the residue and accumulation of impurities in the adsorption area, causing the purification pressure in the adsorption area. Moreover, when the rotor material in the desorption area is desorbed at high temperature, the temperature will be transmitted to the adsorption area, causing the part of the rotor in the adsorption area close to the desorption area to be preheated and desorbed in advance. The waste gas in the adsorption area will separate the desorbed impurities from the rotor and then mix with the purified air, affecting the purification rate. Summary of the Invention

[0027] 2. By installing a surface impurity anti-scratching mechanism, the present invention covers the rotor near the desorption area and located in the adsorption area, avoiding the premature detachment of impurities that are pre-heated and detached from the adsorption area in advance, resulting in the premature discharge of harmful substances and mixing with the purified gas in the adsorption area, reducing the air purification rate. It insulates the pre-heated position to avoid the low-temperature exhaust gas from cooling the heated position, ensuring the temperature of the heated part when it enters the desorption area. In addition, the surface impurity anti-scratching mechanism allows the impurities on the rotor surface to enter the adsorption area without damage, avoiding the accumulation of impurities remaining in the adsorption area when the rotor material rotates to the desorption area.

[0028] 3. By installing a heat preservation and isolation mechanism to cover the pre-heated part, the present invention further avoids the exhaust gas in the adsorption area from contacting the pre-heated area, preventing the premature desorption of premature impurities. In addition, by covering and insulating the pre-heated area, it avoids the low-temperature exhaust gas from cooling the heated position, ensuring the temperature of the heated part when it enters the desorption area. Desorption can be achieved without long-term heating of this position, reducing the heating and desorption time of the rotor material and improving the desorption efficiency.

The inner rod is sleeved inside the outer cylinder, and the spring is fixed on the inner wall of the outer cylinder and fixedly connected to the inner rod.

[0066] Working principle:

[0067] The waste gas enters the interior of the circular shell 23 through the waste gas inlet 15, contacts the zeolite rotor 28 in the adsorption area, then passes through the zeolite rotor 28. The zeolite rotor 28 isolates harmful substances, and the isolated gas is discharged through the clean gas outlet 16.

[0068] After a specified filtering time, it is necessary to gradually desorb and cool and regenerate some positions in the adsorption area. The controller 18 controls the opening of the control valve in the desorption frame air supply pipe 13, and then controls the electromagnet two 44 to magnetically attract the piston plate 31. The hot gas supply assembly connected to the desorption frame air supply pipe 13 passes hot gas through the desorption frame air supply pipe 13 and the folding pipe 32 into the space between the piston plate 31 and the baffle 33. The gas pushes the piston plate 31 to move, and the piston plate 31 drives the partition one 41 and the heat preservation and isolation mechanism 5 to move. The partition one 41 disengages from the zeolite rotor 28. Since both sides of the U-shaped frame 42 are blocked by the desorption frame one 29 and the fixed cylinder 213, the gas inside the U-shaped frame 42 will enter the cavity one 410 through the pipe 49, causing the partition three 412 to pull the spring telescopic rod three 411 to move. The inner rod of the spring telescopic rod three 411 pulls the spring inside the outer cylinder to stretch. The partition three 412 moves to press on the roller 416 and the roller mounting frame 415, causing the roller 416 and the roller mounting frame 415 to compress the spring three 414 inside the cavity two 413. One side of the partition three 412 contacts the zeolite rotor 28 and generates friction. The partition two 48, the partition three 412, the roller 416 and the roller mounting frame 415 cover some of the zeolite rotor 28 materials in the adsorption area close to the partition one 41. Since the zeolite rotor 28 material has thermal conductivity, when the hot gas flushes the zeolite material in the desorption area, the zeolite material close to the desorption area will cause some of the materials in the adsorption area to be desorbed in advance due to temperature diffusion. Therefore, when the waste gas enters the adsorption area and the heated part, it will blow out the desorbed materials in advance, thereby reducing the purification rate. Therefore, covering some positions in the adsorption area close to the desorption area can prevent the gas in the adsorption area from entering the interior, thereby preventing the prematurely desorbed substances from being blown out prematurely. Covering the heated part can also prevent the low-temperature waste gas from cooling the heated position. Because when the heated part enters the adsorption area, the heating time of this part through the hot gas can be reduced, saving time and efficiency. At the same time, the heated part is covered by the closing plate 51 and the heat preservation layer 52 for further heat preservation;

[0069] Further seal the heated part, and then stop the gas supply. The partition three 412 is in close contact with the zeolite rotor 28. Then control the motor 26 to drive the rotating shaft 24 and the zeolite rotor 28 to rotate. The zeolite rotor 28 drives the partition two 48, the partition three 412, the roller 416 and the roller mounting frame 415 to move along by friction. During the movement, the spring telescopic rod two 46 and the spring telescopic rod four 419 are squeezed. The spring telescopic rod two 46 and the spring telescopic rod four 419 are compressed and contracted. Under the condition of heat preservation, the heated part rotates into the desorption area through the gap between the partition one 41 and the zeolite rotor 28. The movement of the partition one 41 to generate a gap with the zeolite rotor 28 can cause the impurities on the surface layer of the zeolite rotor 28 to enter the desorption area together, preventing the impurities from being blocked outside the desorption area, resulting in the accumulation of impurities in the adsorption area that cannot be desorbed and treated by the desorption area;

[0070] Turn off the motor 26, the zeolite rotor 28 stops rotating, turn off the electromagnet two 44, and the magnetic attraction between the piston plate 31 is released. The spring two 43 pushes the partition one 41 to move to reorganize the desorption area. The heat insulation and isolation mechanism 5 performs heat insulation and isolation on the next heated part. When the partition one 41 moves, the gas in the cavity one 410 will be evacuated. The spring telescopic rod three 411 pulls the partition three 412 to reset. At the same time of resetting, the roller 416 contacts the zeolite rotor 28 to ensure the sealing performance. When the partition three 412 is no longer in contact with the zeolite rotor 28, the spring telescopic rod two 46 and the spring telescopic rod four 419 push the partition two 48, the partition three 412, the roller 416 and the roller mounting bracket 415 to move back to their original positions. The roller 416 rolls on the zeolite rotor 28 to prevent the impurities on the surface of the zeolite rotor 28 from being scraped off and following, ensuring that the impurities on the surface of the zeolite rotor 28 can enter the desorption area for treatment without damage;

[0071] Continue to supply gas between the piston plate 31 and the baffle 33. After supplying the specified pressure (the pressure is detected by an external gas supply component), start the electromagnet one 38 to suck the sealing plate 39 over, compress the spring one 37, and open the air outlet 34. Because when the piston plate 31 moves, it pulls the inner rod of the spring telescopic rod one 310 to move, stretching the internal spring. When the air outlet 34 is opened, the spring pulls the piston plate 31 to move to squeeze the gas out through the air outlet 34 to form an impact gas. The impact gas contacts the previous heated part and causes it to vibrate. The vibration improves the desorption efficiency. The hot air enters the interior of the heated part, flushing the impurities desorbed in advance and the impurities desorbed by vibration into the interior of the desorption frame two 212, and then entering the next processing device through the desorption frame outlet pipe 12. After the gas impact contact, turn off the electromagnet one 38 to block the air outlet 34 and wait for the next heated position to enter the desorption area when the zeolite rotor 28 rotates next time. The position where the desorption is completed rotates into the cooling area. The cold air enters through the cooling frame air supply pipe 14, passes through the zeolite rotor 28 to cool it, enabling it to restore its adsorption capacity, and then is discharged from the cooling frame outlet pipe 17. The above steps are used to achieve cyclic filtration.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
