Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, and in particular to a zeolite rotary adsorption device. Background Technology

[0002] The zeolite rotary adsorption system uses a rotating zeolite wheel to concentrate large volumes of low-concentration VOCs waste gas into small volumes of high-concentration waste gas. The zeolite rotary adsorption device is a commonly used equipment for industrial waste gas treatment. Based on the adsorption and desorption characteristics of zeolite materials, it achieves the removal and concentration of harmful substances in waste gas.

[0003] Traditional waste gas adsorption devices suffer from problems such as poor waste gas flow and insufficient contact area. After the waste gas enters, dead zones are easily formed, resulting in insufficient contact between the zeolite and the waste gas and low adsorption efficiency. Especially when treating high-concentration waste gas, excessively fast or slow local airflow can cause blockage on the zeolite surface, affecting the long-term operational stability of the device. To address these issues, we propose a zeolite rotary adsorption device. Utility Model Content

[0004] The purpose of this invention is to provide a zeolite rotary adsorption device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A zeolite rotary adsorption device includes an adsorption cylinder, a rotary motor fixedly connected to the upper surface of the adsorption cylinder, a main rotating shaft fixedly connected to the output end of the rotary motor, a plurality of zeolite placement frames fixedly connected to the outer surface of the main rotating shaft, a plurality of support members fixedly connected to the inner wall of the adsorption cylinder, a plurality of guide vanes fixedly connected to the lower part of the outer surface of the main rotating shaft, and a guide shroud fixedly connected to the inner bottom wall of the adsorption cylinder.

[0007] In a further embodiment, an air inlet pipe is fixedly connected to the bottom surface of the adsorption cylinder, and an exhaust pipe is fixedly connected to the top surface of the adsorption cylinder.

[0008] In a further embodiment, the bottom surface of the adsorption cylinder is fixedly connected to a plurality of bases with openings, and the front surface of the adsorption cylinder is provided with an arc-shaped cover plate.

[0009] In a further embodiment, each of the supports includes a flow guide ring fixedly connected to the inner wall of the adsorption cylinder, and the bottom of the flow guide ring is inclined at 45 degrees.

[0010] In a further embodiment, each of the flow guide rings has an annular groove on its upper surface, and a sliding ring is slidably connected inside each annular groove. The top end of each sliding ring is fixedly connected to the bottom surface of the zeolite placement frame.

[0011] In a further embodiment, the inner wall of the adsorption cylinder is fixedly connected with a plurality of fixed connecting rods, and the bottom surface of each fixed connecting rod is fixedly connected with a plurality of dispersing rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses guide vanes that rotate with the main shaft to evenly throw the exhaust gas from the inlet pipe onto the inner wall of the adsorption cylinder. Combined with the converging effect of the guide hood, the exhaust gas rises in a spiral shape, covering all the zeolite placement frames. Furthermore, the inclined design of the bottom of the guide ring of the support component guides the exhaust gas to converge towards the center along the annular groove, avoiding airflow short-circuiting and ensuring full contact between the exhaust gas and zeolite particles, significantly increasing the adsorption area. In addition, the dispersing rod of the fixed connecting rod rotates with the main shaft, continuously agitating the zeolite particles to prevent clumping caused by adsorption saturation and maintain the permeability of the zeolite surface.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 In this utility model, a zeolite rotary adsorption device includes an adsorption cylinder 1. A rotary motor 6 is fixedly connected to the upper surface of the adsorption cylinder 1. A main rotating shaft 7 is fixedly connected to the output end of the rotary motor 6. Multiple zeolite placement frames 8 are fixedly connected to the outer surface of the main rotating shaft 7. Multiple support members 11 are fixedly connected to the inner wall of the adsorption cylinder 1. Multiple guide vanes 9 are fixedly connected to the lower part of the outer surface of the main rotating shaft 7. A guide hood 10 is fixedly connected to the inner bottom wall of the adsorption cylinder 1. The zeolite placement frames 8 are driven to rotate by the rotary motor 6. The guide vanes 9 and the guide hood 10 work together to guide the airflow, so that the waste gas passes through the zeolite layer in a spiral path, solving the problem of dead airflow in traditional devices.

[0024] An air inlet pipe 4 is fixedly connected to the bottom surface of the adsorption cylinder 1, and an exhaust pipe 5 is fixedly connected to the top surface of the adsorption cylinder 1. The air inlet pipe 4 and the exhaust pipe 5 are distributed vertically to form a convection channel with the bottom inlet and the top outlet. With the agitation of the guide vanes 9, the exhaust gas is ensured to form a stable vortex in the cylinder, avoiding short-circuiting. Multiple bases 3 with openings are fixedly connected to the bottom surface of the adsorption cylinder 1. An arc-shaped cover plate 2 is provided on the front of the adsorption cylinder 1, and a sealing ring is provided on the side of the arc-shaped cover plate 2 near the adsorption cylinder 1 to prevent exhaust gas leakage. The bases with openings 3 provide stable support, and the arc-shaped cover plate 2 facilitates quick replacement of the failed zeolite, which is especially suitable for industrial scenarios that require regular maintenance and reduces downtime.

[0025] Each support 11 includes a guide ring 111 fixedly connected to the inner wall of the adsorption cylinder 1, with the bottom of the guide ring 111 inclined at 45 degrees. An annular groove 112 is formed on the upper surface of each guide ring 111, and a sliding ring 113 is slidably connected inside each annular groove 112. The top of each sliding ring 113 is fixedly connected to the bottom surface of the zeolite placement frame 8. The 45° inclined bottom surface of the guide ring 111 guides the exhaust gas towards the center. The sliding ring 113 ensures the stability of the zeolite placement frame 8 during rotation, allowing the exhaust gas to pass evenly through each layer of zeolite. Multiple fixed connecting rods 12 are fixedly connected to the inner wall of the adsorption cylinder 1, and the bottom surface of each fixed connecting rod 12 is fixedly connected to... Multiple dispersing rods 13 and fixed connecting rods 12 can disperse the zeolite in the zeolite placement frame 8 that rotates with the main shaft 7, continuously dispersing agglomerated zeolite, maintaining unobstructed exhaust gas flow, and preventing pressure drop caused by zeolite accumulation. After the exhaust gas enters from the inlet pipe 4, it is first thrown towards the cylinder wall by the guide vanes 9 to form an initial vortex. The guide shroud 10 gathers the airflow to the bottom of the zeolite placement frame 8, and the inclined guide ring 111 guides the airflow to diffuse upward along the annular groove 112, ensuring that each zeolite particle is in full contact with the exhaust gas. The dispersing rods 13 simultaneously agitate the zeolite layer to prevent the accumulation of saturated adsorbed particles, maintain unobstructed airflow, and finally discharge the exhaust gas through the exhaust pipe 5.

[0026] The working principle of this utility model is as follows:

[0027] When treating organic waste gas from a printing plant, first open the arc-shaped cover 2 and place an appropriate amount of zeolite in each layer of zeolite placement frame 8. After closing the arc-shaped cover 2, the waste gas enters through the inlet pipe 4. The rotary motor 6 can be started to rotate the main shaft 7, and the guide vanes 9 can rotate with the main shaft 7 to evenly throw the waste gas onto the cylinder wall. The gas is then guided upward by the guide hood 10. Moreover, the zeolite placement frame 8 rotates synchronously with the main shaft 7, ensuring that the upward-flowing waste gas comes into full contact with the zeolite particles. The clean gas after adsorption is discharged from the exhaust pipe 5. The actual adsorption efficiency is significantly improved compared to the traditional static adsorption device.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
