Description

Technical Field

[0001] The invention relates to the technical field of zeolite concentration rotors, and more specifically to a novel zeolite concentration rotor module for VOC treatment. Background Art

[0002] The zeolite concentrating rotor is a modular device for adsorbing volatile organic compounds in exhaust gas. Most of them are installed in integrated VOC treatment equipment for use, and are used to purify VOC in exhaust gas. The zeolite concentrating rotor is generally divided into a treatment adsorption zone, a desorption zone, and a cooling zone. The zeolite rotor rotates at a certain speed to allow the exhaust gas to enter the zeolite wheel core, and then the VOC is adsorbed and removed under the action of the adsorbent. Finally, the purified air is discharged from the treatment zone of the zeolite concentrating rotor. At present, the zeolite wheel core is mostly a whole. When the zeolite wheel core adsorbs, purifies and discharges VOC, if part of it is damaged, it needs to be replaced as a whole. In addition, large zeolite wheel core modules have certain difficulties in transportation, installation and maintenance, and the cost is high. When desorbing VOC by hot air, due to the integrity of the zeolite wheel core, the zeolite wheel core part adjacent to the desorption zone is difficult to effectively adsorb VOC. Therefore, it is necessary to provide a new zeolite concentrating rotor module for VOC treatment to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0037] See also Figure 1 to Figure 7 In an embodiment of the present invention, a novel zeolite concentrating rotor module for VOC treatment includes:

[0038] Fixed frame 1;

[0039] A rotating mechanism 2 is fixed on the fixed frame 1;

[0040] The zeolite wheel concentrator 3 is fixedly connected to the upper part of the rotating mechanism 2;

[0041] The closed conveying device 4 is provided at the upper and lower parts and the side parts of the zeolite wheel concentrator 3 .

[0042] In this embodiment, the rotating mechanism 2 includes:

[0043] A rotating motor 21 is fixed at the center of the fixed frame 1;

[0044] The connecting shaft 22 is fixedly connected to the rotating motor 21 and is also fixedly connected to the inner side of the zeolite wheel concentrator 3 .

[0045] That is to say, driven by the rotating motor 21, the zeolite wheel concentrator 3 is driven to rotate slowly through the connecting shaft 22, and then the exhaust gas is transported from the upper part of the closed conveying device 4 to the zeolite wheel concentrator 3, and under the adsorption action of the zeolite wheel concentrator 3, VOC is removed, and the purified exhaust gas is discharged through the lower part of the closed conveying device 4.

[0046] In this embodiment, the zeolite wheel concentrator 3 comprises:

[0047] Connecting inner ring 31, fixedly connected to rotating mechanism 2;

[0048] A plurality of zeolite wheel units 32 are provided in an annular arrangement and are fixed between the connecting inner ring 31 and the closed conveying device 4 .

[0049] That is, the rotating motor 21 drives the connecting inner ring 31 to rotate through the connecting shaft 22, and then drives the zeolite wheel unit 32 to rotate between the closed conveying device 4 to purify the VOC in the exhaust gas.

[0050] In this embodiment, the zeolite wheel concentrator 3 also includes an adsorption area 33, a transition area 34, a desorption area 35 and a cooling area 36, ​​the adsorption area 33 corresponds to multiple zeolite wheel units 32, and the transition area 34, the desorption area 35 and the cooling area 36 correspond to a single zeolite wheel unit 32 respectively.

[0051] That is to say, driven by the rotating mechanism 2, the zeolite rotor unit 32 passes through the adsorption area 33, the transition area 34, the desorption area 35 and the cooling area 36 in sequence. In the adsorption area 33, the exhaust gas enters the zeolite rotor unit 32, adsorbs the VOC, and discharges the purified exhaust gas. As the rotating mechanism 2 rotates, the zeolite rotor unit 32 enters the transition area 34. In the transition area 34, the zeolite rotor unit 32 is isolated from the exhaust gas to prevent the exhaust gas from entering. Then, it enters the desorption area 35, and the VOC adsorbed on the zeolite rotor unit 32 is removed by hot air. Driven by the hot air, it is transported to the combustion device for combustion treatment. After the desorption is completed, it enters the cooling area 36 to cool the zeolite rotor unit 32, and then enters the adsorption area 33 again to adsorb and purify the exhaust gas.

[0052] In this embodiment, the closed conveying device 4 includes:

[0053] The pre-treatment component 41 is disposed above the zeolite wheel unit 32 and corresponds to the adsorption area 33;

[0054] A fixed outer ring 42 is arranged outside the zeolite wheel unit 32;

[0055] The discharge assembly 43 is disposed below the zeolite wheel unit 32 , with the top connected to the pre-treatment assembly 41 via a fixed outer ring 42 , and the bottom fixedly connected to the fixing frame 1 .

[0056] That is to say, the exhaust gas is preliminarily treated by the pre-treatment component 41 to remove particulate matter to ensure the absorption efficiency of the zeolite, and then the exhaust gas enters the zeolite wheel unit 32 in the adsorption area 33, and after adsorption and purification, it is discharged downward and discharged through the discharge component 43.

[0057] In this embodiment, the zeolite wheel unit 32 includes:

[0058] The connecting body 321 is rotatably connected to the closed conveying device 4;

[0059] Two fixing plates 322 are symmetrically arranged about the connecting body 321 and fixed to the outer side of the connecting inner ring 31;

[0060] Two spacer frames 323 are symmetrically arranged and disposed between the fixing plates 322 and fixedly connected to the connecting inner ring 31;

[0061] The zeolite module 324 is fixed on the spacer frame 323 .

[0062] That is to say, in the adsorption area 33, the exhaust gas is transported to the zeolite wheel unit 32 through the exhaust gas inlet channel between the spacing frames 323. Since the bottom of the channel is in a closed state, the exhaust gas flows to both sides, passes through the zeolite module 324, and flows to the side channels between the fixed plates 322 and the spacing frames 323 on both sides. When passing through the zeolite module 324, VOCs in the exhaust gas are removed, and the purified exhaust gas flows to the exhaust component 43 through the side channel between the fixed plate 322 and the spacing frame 323, and is discharged from the exhaust component 43.

[0063] In this embodiment, the upper and lower ends of the transition area 34 are respectively provided with closed panels 341 corresponding to the zeolite wheel unit 32 .

[0064] That is to say, since the exhaust gas inlet channel is in the middle of the zeolite wheel unit 32, when the zeolite wheel unit 32 gradually enters the transition area 34, the exhaust gas can still continue to enter the zeolite wheel unit 32, pass through the zeolite module 324 on the side away from the transition area 34 for adsorption and purification, and then be discharged until the exhaust gas inlet channel rotates into the closed panel 341, and the zeolite wheel unit 32 stops the adsorption and purification of the exhaust gas.

[0065] In this embodiment, a hot air conveying component 351 is provided at the bottom of the desorption area 35 , and an exhaust gas conveying component 352 corresponding to the hot air conveying component 351 is provided at the top.

[0066] That is to say, when the zeolite rotor unit 32 rotates from the transition area 34 to the desorption area 35, as the zeolite rotor unit 32 gradually rotates, the bottom hot air delivery component 351 delivers hot air to the side channel between the fixed plate 322 and the spacing frame 323. When the exhaust gas inlet channel between the spacing frames 323 enters the desorption area 35, the hot air enters from the side channel, back-blows away the VOC adsorbed on the zeolite module 324, and is taken out to the exhaust gas delivery component 352 through the exhaust gas inlet channel between the spacing frames 323, and is delivered to the combustion device by the exhaust gas delivery component 352 for combustion. Combustion treatment is carried out; when the zeolite rotor unit 32 rotates from the desorption area 35 to the cooling area 36, ​​the side channel between the fixed plate 322 and the spacing frame 323 first enters the cooling area 36 for cooling, and then the exhaust gas enters the channel between the spacing frames 323 and enters the cooling area 36. At this time, the hot air can no longer flow in the zeolite rotor unit 32, and then the exhaust gas entering the channel area is cooled. As the zeolite rotor unit 32 enters the cooling area 36 in its entirety, the hot air is lost, and the side channel portion of the zeolite rotor unit 32 that enters the cooling area 36 later is cooled during the gradual rotation.

[0067] In this embodiment, cooling panels 361 corresponding to the zeolite wheel units 32 are respectively provided at the upper and lower ends of the cooling area 36 .

[0068] That is to say, when the zeolite wheel unit 32 rotates into the cooling area 36, ​​under the action of the cooling panel 361, the side channel part, the exhaust gas inlet channel part and the side channel part are closed in turn to isolate the transportation of hot air, and then the zeolite wheel unit 32 is gradually cooled by the cooling area 36 so as to enter the adsorption area 33 again to adsorb and purify the VOC in the exhaust gas.

[0069] During the specific implementation, first, driven by the rotating mechanism 2, the zeolite rotor unit 32 passes through the adsorption area 33, the transition area 34, the desorption area 35 and the cooling area 36 in sequence, and transports the exhaust gas to the zeolite rotor concentration device 3 through the top of the closed conveying device 4. The exhaust gas is preliminarily treated by the pre-treatment component 41 to remove particulate matter to ensure the absorption efficiency of the zeolite, and then the exhaust gas enters the zeolite rotor unit 32 in the adsorption area 33. The exhaust gas is transported to the zeolite rotor unit 32 through the exhaust gas entry channel between the spacing frames 323, and flows to the side channel between the fixed plates 322 and the spacing frames 323 on both sides through the zeolite module 324. When passing through the zeolite module 324, VOC in the exhaust gas is removed, and then the purified exhaust gas flows to the exhaust component 43 through the side channel between the fixed plate 322 and the spacing frame 323, and is discharged from the exhaust component 43. As the rotating mechanism 2 rotates, the zeolite rotor unit 32 enters the transition area 34. In the transition area 34, the zeolite The zeolite rotor unit 32 is isolated from the exhaust gas to prevent the exhaust gas from entering, so that the exhaust gas adsorption work and the VOC desorption work are completely isolated, and the mutual influence between the two processes is effectively avoided. Then the zeolite rotor unit 32 enters the desorption area 35, and the VOC adsorbed on the zeolite rotor unit 32 is removed by hot air. The hot air enters from the side channel, back-blows away the VOC adsorbed on the zeolite module 324, and is taken out to the exhaust gas conveying component 352 through the exhaust gas inlet channel between the spacing frames 323. The exhaust gas conveying component 352 conveys it to the combustion device for combustion treatment. After the desorption is completed, the zeolite rotor unit 32 enters the cooling area 36. Under the action of the cooling panel 361, the side channel part, the exhaust gas inlet channel part and the side channel part are closed in turn to isolate the transportation of hot air, and then the cooling area 36 gradually cools the zeolite rotor unit 32 so that it can enter the adsorption area 33 again to adsorb and purify the VOC in the exhaust gas.
