[0056] like Figure 1 and Figure 2 As shown, the VOCS zeolite rotor treatment system includes an integrated housing 1, the interior of which is divided into a normal temperature zone 11 and a heat preservation zone 12. Normal temperature zone 11 houses a pre-filtration device 2 and a zeolite rotor adsorption device 3, while heat preservation zone 12 houses a catalytic heat exchange module 4, which is connected to the zeolite rotor adsorption device 3 via a pipeline module 5. Heat preservation zone 12 is filled with insulation material to isolate the high-temperature catalytic heat exchange module 4 from other equipment, minimizing the impact of high temperatures on equipment in normal temperature zone 11. This reduces heat radiation and thermal pollution, thereby improving heat recovery efficiency.

[0057] like Figure 3 、 Figure 4 and Figure 5As shown, the front filter device 2 includes a first filter unit 21, a second filter unit 22 and a third filter unit 23. In the airflow direction, the first filter unit 21, the second filter unit 22 and the third filter unit 23 are arranged in parallel in sequence to perform multi-stage filtration on the exhaust gas entering the all-in-one housing 1.

[0058] The filtered gas flows into the zeolite wheel adsorption device 3 for treatment. The zeolite wheel adsorption device 3 includes a zeolite wheel 31 and two brackets 37. The brackets 37 are fixed on the integrated machine housing 1. The two brackets 37 are arranged in parallel and spaced apart. Figure 6 and Figure 7 As shown, the bracket 37 is provided with an air flow hole corresponding to the position of the zeolite runner 31, and an annular sealing ring 372 is fixed in the air flow hole. The two ends of the zeolite runner 31 extend into the annular sealing ring 372 and are mounted on the shaft seat 371 of the bracket 37 by shaft rotation. In the flow direction of the airflow, the bracket 37 located upstream of the zeolite runner 31 is provided with a first partition interface device 32, and the bracket 37 located downstream of the zeolite runner 31 is provided with a second partition interface device 33 and a third partition interface device 34. The first partition interface device 32 and the second partition interface device 33 correspond to the desorption zone, and the third partition interface device 34 corresponds to the cooling zone; the first partition interface device 32, the second partition interface device 33 and the third partition interface device 34 are all provided with a sliding sealing mechanism 6 between the end face of the zeolite runner 31.

[0059] like Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the sliding sealing mechanism 6 includes an arcuate sealing component 62. At least a first radial sealing component 61 and a second radial sealing component 64 are provided between the arcuate sealing component 62 and the annular sealing ring 372. The first radial sealing component 61 and the second radial sealing component 64 both extend radially along the annular sealing ring 372. The first radial sealing component 61, the arcuate sealing component 62, the second radial sealing component 64 and the annular sealing ring 372 are sequentially connected and sealed to form a desired partition, such as the desorption zone corresponding to the first partition interface device 32. As for the second partition interface device 33 and the third partition interface device 34, as shown in FIG. Figure 6 and Figure 7 As shown, it also includes a third radial sealing component 63, which extends radially along the annular sealing ring 372 and seals the desorption zone and the cooling zone together with the first radial sealing component 61, the arc-shaped sealing component 62, the second radial sealing component 64 and the annular sealing ring 372.

[0060] The third radial seal assembly 63, the first radial seal assembly 61 and the second radial seal assembly 64 each include a main seal plate 653, a connecting intermediate body 651 and an auxiliary seal strip 652. Figure 8 As shown. The main sealing plate 653 is provided with strip-shaped mounting holes and is secured to the mounting beam of the bracket 37 via bolts located within the strip-shaped mounting holes. The connecting intermediate body 651 is secured to the main sealing plate 653, and the auxiliary sealing strip 652 is secured to the side of the connecting intermediate body 651 facing away from the main sealing plate 653. Preferably, the connecting intermediate body 651 is a rectangular tube, with the main sealing plate 653 and the auxiliary sealing strip 652 located on opposite outer walls of the rectangular tube.

[0061] The third radial seal assembly 63 is located between the desorption zone and the cooling zone, and has higher sealing requirements. Figure 10 As shown, the third radial seal assembly 63 also includes an auxiliary seal module, which includes a first seal plate 655 and a second seal plate 654. The first seal plate is fixed to the bracket 37 and is sealed therewith, while the second seal plate 654 is fixed to the first seal plate 655. Taking into account installation and spatial arrangement, the first seal plate 655 and the main seal plate 653 are arranged side by side and fixed to the two sides of the mounting beam respectively. The connecting intermediate body 651, the auxiliary seal strip 652, and the second seal plate 654 are located between the first seal plate 655 and the main seal plate 653, corresponding to the width area of ​​the mounting beam.

[0062] like Figure 9 As shown, the arcuate sealing assembly 62 includes an arcuate main diaphragm 621, an inner arcuate sealing strip 622, and an outer arcuate sealing strip 623. The arcuate main diaphragm is fixed to the mounting beam of the bracket 37 and is coaxially arranged with the annular sealing ring 372. The inner arcuate sealing strip 622 and the outer arcuate sealing strip 623 are respectively mounted on the concave and convex sides of the arcuate main diaphragm 621. Specifically, the inner arcuate sealing strip 622 and the outer arcuate sealing strip 623 are fixed to the arcuate main diaphragm 621 via bolts. The arcuate main diaphragm 621 has a strip-shaped hole and is fixed to the bracket 37 via bolts located in the strip hole, thereby sealing the arcuate main diaphragm 621 to the bracket 37. The arcuate sealing assembly 62 and the end surface of the zeolite wheel 31 also form a double-layer seal, that is, the inner arcuate sealing strip 622 and the outer arcuate sealing strip 623 achieve a seal.

[0063] When the zeolite rotor 31 is assembled with the bracket 37, the arc-shaped sealing component 62, the first radial sealing component 61, the second radial sealing component 64 and the third radial sealing component 63 can be moved in the axial direction of the zeolite rotor 31 through the strip hole structure, thereby adjusting the sealing gap between the end face of the zeolite rotor 31, thereby obtaining the best sealing effect and improving the working efficiency of the zeolite rotor 31.

[0064] like Figure 3、 Figure 4 and Figure 5 As shown, after the airflow filtered by the pre-filter device 2 is adsorbed by the zeolite rotor 31, the main airflow is discharged from the integrated machine through the exhaust channel 56, the exhaust fan 57, and the external exhaust pipe 58. The remaining part enters the catalytic heat exchange module 4 under the guidance of the pipeline module 5. Specifically, the gas flows into the third partition interface device 34, and then flows through the first pipe 52, the catalytic heat exchange module 4, the second pipe 53, the second partition interface device 33, the zeolite rotor 31, and the first partition interface device 32 in sequence, desorbing the zeolite rotor 31. The concentrated exhaust gas after desorption passes through the third pipe 51 and the concentrating fan 54 and enters the catalytic heat exchange module 4, which processes the concentrated exhaust gas and recovers and utilizes the heat.

[0065] Specifically, such as Figure 11 As shown, the catalytic heat exchange module 4 includes a combustion furnace 45, a desorption gas heat exchange module 41 and a concentrated gas heat exchange module 42. The desorption gas heat exchange module 41 and the concentrated gas heat exchange module 42 are arranged side by side up and down, and are arranged near the gas outlet of the combustion furnace 45, so as to reduce the length of the pipeline and reduce heat loss. The desorption gas heat exchange module 41 has a first high-temperature exhaust gas flow channel and a desorption gas flow channel, and the concentrated gas heat exchange module 42 has a second high-temperature exhaust gas flow channel and a concentrated gas flow channel. Among them, the first high-temperature exhaust gas flow channel and the second high-temperature exhaust gas flow channel are connected through the second guide box 43.

[0066] The concentrated exhaust gas flows into the concentrated gas flow channel through third pipe 51, where it is preheated in concentrated gas heat exchange module 42 before flowing into combustion furnace 45 through fourth pipe 47. A second heating device 46 is installed on fourth pipe 47. If the preheating temperature does not meet the catalytic reaction requirements, second heating device 46 reheats the concentrated exhaust gas to ensure the catalytic treatment effect. Second heating device 46 can be an electrically heated heat exchanger.

[0067] The high-temperature flue gas discharged from the combustion furnace 45 flows sequentially through the first high-temperature exhaust gas flow channel, the second guide box 43, and the second high-temperature exhaust gas flow channel before being discharged from the integrated unit through the fifth pipe 48. The gas flowing into the third partition interface device 34 is sent to the desorption gas flow channel through the first pipe 52, heated in the desorption gas heat exchange module 41, and then sent to the second partition interface device 33 through the second pipe 53 for desorption treatment on the zeolite rotor 31. Furthermore, a first heating device 55 is provided on the second pipe 53. When the temperature of the gas flowing out of the desorption gas heat exchange module 41 does not meet the desorption requirements, the first heating device 55 is controlled to heat the gas again to ensure the desorption effect. The first heating device 55 can be an electrically heated heat exchanger.

[0068] like Figure 11 and Figure 12As shown, the desorbed gas heat exchange module 41 and the concentrated gas heat exchange module 42 each have two heat exchange bodies 7, and the two heat exchange bodies 7 are located in the shell. Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 As shown, each heat exchanger 7 includes several heat exchange units 71, which are stacked and welded together. Each heat exchange unit 71 is composed of two heat exchange unit bodies 76 welded together. Within the heat exchanger 7, a first flow channel 75 is formed between two adjacent heat exchange units 71, and a second flow channel 74 is formed between the two heat exchange unit bodies 76 of the same heat exchange unit 71. When the two heat exchangers 7 are placed side by side and welded together, the first flow channels 75 in the two heat exchangers 7 correspond to each other and are connected. The second flow channels 74 in the two heat exchangers 7 are connected through the first flow guide box 44.

[0069] For the desorption gas heat exchange module 41, multiple first flow channels 75 constitute the first high-temperature exhaust gas flow channel, and multiple second flow channels 74 constitute the desorption gas flow channel; and for the concentrated gas heat exchange module 42, multiple first flow channels 75 therein constitute the second high-temperature exhaust gas flow channel, and multiple second flow channels 74 constitute the concentrated gas flow channel.

[0070] like Figure 16 As shown, the heat exchange unit 76 is a rectangular plate, equipped with a first flange group and a second flange group. The first flange group includes two first bends 73, located at two opposing edges of the heat exchange unit 76. The first bend 73 has a first flange 732 and a second flange 731. The first flange 732 is connected to the heat exchange unit 76 and extends toward the second flow channel 74. The first flange 732 and the heat exchange unit 76 are perpendicular or at a set angle. The second flange 731 connects to the first flange 732 and extends outward from the heat exchange unit 76.

[0071] The second flange group includes two second bends 72 located at the other two opposing edges of the heat exchange unit 76. The second bend 72 includes a third flange 722 and a fourth flange 721. The third flange 722 connects to the heat exchange unit 76 and extends toward the first flow channel 75. The third flange 722 and the heat exchange unit 76 are perpendicular or at a predetermined angle. The fourth flange 721 connects to the third flange 722 and extends outward from the heat exchange unit 76.

[0072] In the same heat exchange unit 71 , the first bending portions 73 of the two heat exchange unit bodies 76 are butted one by one, welded together and sealed; the second bending portions 72 of the two adjacent heat exchange units 71 are butted one by one, welded together and sealed.

[0073] like Figure 17 and Figure 18 As shown, the heat exchanger 76 also includes several expansion joints 8. The expansion joints 8 are elongated and are used to seal the ends of the first bend 73 and the second bend 72. The expansion joints 8 include a U-shaped body 81, which has an airflow channel 82 therein; both ends of the airflow channel 82 are sealed by end plates 83. The expansion joints 8 are welded and sealed to the heat exchange unit 76 as a whole. One of the side surfaces of the U-shaped body 81 forms a sealing surface, which is welded and sealed to the end surface of the first bend 73, sealing the side opening of the first bend 73. In other words, the side opening of the first flow channel 75 at the junction of the two heat exchangers 7 is closed, allowing airflow to flow in only one direction. After the U-shaped body 81 is welded to the second bend 72, the opening of the airflow channel 82 faces the second flow channel 74 and is connected. The airflow channel 82 allows airflow at the second bend 72 to flow perpendicular to the direction of the airflow, which helps to balance the air pressure within each second flow channel 74 within the heat exchanger and buffer the airflow pressure.

[0074] Optimally, the material of the expansion joint 8 is the same as that of the unit body, which can support the unit body and has a consistent amount of thermal deformation to maintain a stable seal.

[0075] A plurality of first protrusions 78 protruding toward the first flow channel 75 and a plurality of second protrusions 77 protruding toward the second flow channel 74 are stamped in the middle of each heat exchange unit body 76. The first protrusions 78 between two adjacent heat exchange unit bodies 76 correspond one to one, and the second protrusions 77 between two adjacent heat exchange unit bodies 76 correspond one to one. When the heat exchange unit body 76 is installed, the corresponding two first protrusions 78 abut against each other, and the corresponding two second protrusions 77 abut against each other, thereby achieving support for the unit body.

[0076] The heat exchange unit body 76 adopts a one-step molding process, that is, the first bend portion 73, the second bend portion 72, the first convex portion 78 and the second convex portion 77 are hydraulically molded at one time. The first convex portion 78 and the second convex portion 77 can enhance the strength of the heat exchanger and increase the heat exchange area.

[0077] The number of heat exchange units 76 in each heat exchange body 7 can be adjusted according to the heat exchange demand.

[0078] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
