[0002] In the waste gas treatment technical field, volatile organic gas (VOCS gas) treatment is particularly important, and the existing technology mainly includes zeolite rotating adsorption subassembly and heat decomposition of regenerative organic waste gas incinerator (RTO) for VOCs gas treatment. First, the adsorption subassembly with zeolite rotating adsorption adsorbs VOCs gas, and then the VOCs gas adsorbed in the zeolite rotating adsorption is separated from the zeolite rotating adsorption and enters the RTO for heat decomposition into carbon dioxide and water, thereby completing the VOCs gas treatment and ensuring that the waste gas meets the emission standard. Therefore, the performance of the adsorption subassembly directly affects the treatment effect of VOCs gas.

[0003] The adsorption subassembly of VOCs gas in the prior art mainly uses zeolite rotating adsorption. The zeolite rotating adsorption adsorbs VOCs gas during rotation, and then the adsorbed VOCs gas is desorbed and enters the RTO for heat decomposition after the zeolite rotating adsorption rotates to the heat desorption zone. The zeolite rotating adsorption is mainly a disc-shaped member formed by splicing multiple fan-shaped zeolites.

[0004] In the above assembly structure, the zeolite rotating block is embedded in the placement cavity of the rotating frame to complete the installation of the zeolite rotating block. However, the above assembly structure still has certain defects during use, which are as follows.

[0006] To solve the problem, the utility model provides a VOCs adsorption subassembly, which improves the stability of the zeolite block to solve the above problem. UTILITY MODEL CONTENTS

[0059] Secondly, the "one embodiment" or "embodiment" referred to herein means that a certain feature, structure or characteristic can be included in at least one implementation of the utility model. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments. The utility model provides the following embodiments.

[0060] Example 1: As Figures 7-9 As shown, this is a schematic diagram of the structure of the zeolite rotor assembly 200 in this embodiment. The zeolite rotor assembly 200 in this embodiment includes a rotor frame 201, zeolite blocks 202, and clamps 203. In this embodiment, multiple zeolite blocks 202 are provided and have a fan-shaped structure. The zeolite blocks 202 are sequentially installed on the rotor frame 201 to form the zeolite rotor structure. In addition, clamps 203 are connected to the zeolite rotor structure. The clamps 203 fix multiple zeolite blocks 202 on the rotor frame 201 to form the zeolite rotor assembly 200 in this embodiment.

[0061] like Figure 9 As shown, in this embodiment, the rotating frame 201 includes a rotating shaft 204 and fixed frames 205 arranged in a ring on the rotating shaft 204. Zeolite blocks 202 are installed between two adjacent fixed frames 205. To ensure the stability of the installation between the zeolite blocks 202 and the fixed frames 205, as shown... Figure 10 As shown, the fixing frame 205 in this embodiment includes a mounting plate 205a and fixing plates 205b connected to both sides of the mounting plate 205a. In this embodiment, one end of the mounting plate 205a is fixedly connected to the rotating shaft 204, and a U-shaped groove structure is formed between the fixing plates 205b on both sides of the mounting plate 205a and the mounting plate 205a. The zeolite block 202 is installed between adjacent mounting plates 205a, and the zeolite block 202 is limited by the U-shaped groove structure, the effect of which is as follows. Figure 11 and Figure 12 As shown, in this embodiment, the fixing plates 205b on both sides of the mounting plate 205a restrict the movement of the zeolite block 202 along the axial direction of the zeolite wheel assembly 200, thereby ensuring the stability of the zeolite block 202.

[0062] In addition, after multiple zeolite blocks 202 are installed on the wheel frame 201 to form a zeolite wheel structure, a clamp 203 is fitted on the outside of the zeolite wheel structure to limit the zeolite blocks 202, preventing the zeolite blocks 202 from moving along the diameter direction of the zeolite wheel assembly 200, thereby ensuring the stability of the zeolite blocks 202 on the zeolite wheel assembly 200 and improving the performance of the zeolite wheel assembly 200.

[0063] Example 2: To further ensure the stability of the clamp 203 and the wheel frame 201, the zeolite wheel assembly 200 in this example is based on Example 1, as follows: Figures 13-16As shown, the end of the fixing frame 205 is provided with a clamping groove 205c, and the inner wall of the clamping hoop 203 is provided with a protrusion 203a, when the clamping hoop 203 is sleeved on the zeolite runner structure, the protrusion 203a on the inner wall of the clamping hoop 203 is clamped into the clamping groove 205c of the end of the fixing frame 205, thereby improving the fixing effect of the clamping hoop 203 relative to the runner frame 201, in the embodiment, a cavity is formed between the clamping hoop 203 and the fixing frame 205, and the zeolite block 202 is installed in the cavity, on one hand, the stability of the zeolite block 202 is improved due to the limiting of the U-shaped groove structure, and on the other hand, the stability of the zeolite block 202 on the runner frame 201 is further ensured due to the fixation of the clamping hoop 203 relative to the fixing frame 205.

[0064] Therefore, on one hand, the zeolite block 202 is limited by the U-shaped groove structure on the fixing frame 205, and on the other hand, the stability of the zeolite block 202 is further ensured by improving the stability of the clamping hoop 203 relative to the runner frame 201, thereby ensuring the stability of the zeolite runner assembly 200, and facilitating the rotation of the zeolite runner assembly 200 in the shell 100 to adsorb VOCs gas.
