Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gas purification equipment, and in particular to a device for loading and processing catalytic adsorption materials in an adsorption cylinder. Background Technology
[0002] Catalytic filtration is a conventional method for gas purification. Existing gas catalytic filtration technologies generally involve placing layered catalytic adsorbent particles in a gas flow channel to form an adsorption bed. The gas to be treated is then driven to flow through the adsorption bed, allowing harmful components in the gas to come into contact with and react with the adsorbent, thus capturing and purifying them. In some technologies, adsorbent particles are loaded onto porous materials to form an adsorption material; however, during adsorption, the gas to be treated is still driven to pass through the adsorption material for adsorption treatment.
[0003] In this existing catalytic adsorption filtration method, the gas to be treated typically passes through the adsorbent material in a unidirectional vertical direction. This usually presents the following problems: 1. The contact-collision-reaction filtration process between the gas to be treated and the adsorbent material is relatively short, making it difficult to improve adsorption filtration efficiency. 2. Because the gas to be treated passes through the adsorbent material vertically, the initial contact area between the adsorbent material and the gas to be treated has a higher reaction efficiency, while the subsequent contact area has a lower reaction efficiency. This uneven reaction efficiency makes it difficult to control the overall regeneration time of the adsorbent, and this inconsistency in purification efficiency reduces the overall purification effect and efficiency. 3. The gas to be treated passes through the adsorbent material uniformly. After the adsorbent material at the front comes into contact with harmful substances and reacts, it increases in volume and blocks the pore channels, leading to blockage and reducing the purification reaction efficiency of the subsequent adsorbent materials.
[0004] To address the aforementioned issues, the applicant designed an adsorption cylinder structure. The cylinder is cylindrical, with several purification channels of progressively smaller cross-sections evenly distributed along its outer perimeter. A layer of catalytic adsorption material is deposited on the inner wall of each channel. The innermost end of each channel communicates with the inner cavity of the adsorption cylinder via a porous structure loaded with the catalytic adsorption material. A layer of catalytic adsorption material is also placed on both the inner and outer sides of the cylinder. The inner layer of catalytic adsorption material, corresponding to the inner end of the purification channel, has a weak area allowing gas to pass through. This arrangement of the catalytic adsorption purification material on the inner wall of the gradually decreasing diameter purification channel allows it to contact the passing gas and react with and purify harmful components. When the gas is at the rear inlet of the purification channel, the concentration of harmful components is higher, corresponding to a larger area of purification material on the inner wall of the channel. As the gas flows forward through the purification channel, the cross-section gradually decreases, the area of the purification material decreases, but the concentration of harmful components also decreases as the gas is purified, and the flow velocity increases as the cross-section of the purification channel decreases. Therefore, this allows the purification rate to remain highly consistent throughout the purification channel, improving the uniformity of adsorption material usage and thus enhancing the purification efficiency of adsorption treatment.
[0005] However, the loading method of the catalytic adsorption material on the adsorption cylinder in the above-mentioned adsorption cylinder structure is different from that of conventional adsorption packing structure. Therefore, how to load the catalytic adsorption material on the adsorption cylinder more quickly and conveniently has become a technical problem that needs to be further considered and solved. Utility Model Content
[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide an adsorption cylinder with an inward purification flow channel on its outer peripheral wall, and an adsorption cylinder catalytic adsorption material loading and processing equipment that can realize the rapid loading and processing of catalytic adsorption material on the inner wall of the purification flow channel.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] An adsorption cylinder catalytic adsorption material loading and processing device, characterized in that it includes an overall cylindrical shell with a depth greater than the height of the adsorption cylinder. The inner diameter of the shell is greater than the outer diameter of the adsorption cylinder, and a central tube is vertically fixed at the axial position. A pressure plate is set at the upper end of the central tube corresponding to the height of the adsorption cylinder. The pressure plate matches the shape of the upper end of the adsorption cylinder and is used to press and fix the adsorption cylinder. The central tube has a central tube vent hole. An end cap is also set at the upper end of the shell. An upper gas pipe is connected upward from the middle of the end cap. The lower end of the upper gas pipe passes through the end cap and... After the end cap is closed, it is connected to the central tube. An upper fan is installed on the upper air pipe. An upper feeding pipe with a switch valve is also connected to the upper air pipe between the upper fan and the end cap. The upper feeding pipe is connected to an upper feeding box. A hollow interlayer is provided on the outer shell and a lower air pipe is connected to it. A lower fan is installed on the lower air pipe. A lower feeding pipe with a switch valve is also connected to the lower air pipe between the lower fan and the outer shell. The lower feeding pipe is connected to a lower feeding box. An outer shell air hole communicating with the hollow interlayer is opened on the inner wall of the outer shell.
[0009] In this way, when the processing equipment is working, first open the end cover, and insert the adsorption cylinder into the central tube according to its own layers. Use a pressure plate to fix the adsorption cylinder and seal the upper port of the adsorption cylinder to complete the installation of the adsorption cylinder. Then close the end cover. First turn on the lower fan to guide the airflow, so that the inner cavity of the adsorption cylinder generates an outward negative pressure. Then add granular catalytic adsorption material through the upper feeding box. It enters the inner cavity of the adsorption cylinder with the negative pressure airflow through the upper feeding pipe and the central tube. Under the action of negative pressure, it adheres and fixes to the inner wall of the adsorption cylinder to complete the load, forming a layer of catalytic adsorption material on the inner wall of the adsorption cylinder. Then turn off the lower fan and turn on the upper fan to create an upward airflow negative pressure. Then add granular catalytic adsorption material through the lower feeding box. It enters the inner cavity of the outer shell with the negative pressure airflow through the lower feeding pipe and the hollow interlayer on the outer shell. Under the action of negative pressure, it adheres and fixes to the outer wall of the adsorption cylinder and the inner wall of the purification channel to complete the load, forming a layer of catalytic adsorption material on the outer wall of the adsorption cylinder and the inner wall of the purification channel. During the loading process, under the negative pressure of the upward airflow, the inner end of the purification channel is the thinnest part of the adsorption cylinder. The inward airflow is the strongest at this point, which can blow away some of the inner adsorption material that was previously loaded at this point. Therefore, after the loading is completed, the catalytic adsorption material at this point on the inner wall of the adsorption cylinder is relatively thin, which can naturally form a weak area that allows gas to pass through.
[0010] Furthermore, atomizing nozzles are respectively provided on the outer wall of the central tube and the inner wall of the outer shell, and the atomizing nozzles are connected to the loaded agent source through the spray pipe.
[0011] In this way, during the loading of the catalytic adsorption material, while or before adding the catalytic adsorption material, the atomizing nozzle sprays out a mist of the loading agent. The main component of the loading agent is a binder, which can better cooperate with the negative pressure airflow to complete the loading of the catalytic adsorption material on the inner and outer side walls of the adsorption cylinder and the inner wall of the purification channel, thereby improving the adhesion of the catalytic adsorption material.
[0012] Furthermore, the pressure plate is installed on the central tube by means of a threaded connection.
[0013] This facilitates the loading and unloading of the pressure plate to enable the installation of the adsorption cylinder.
[0014] Furthermore, a positioning cone is provided on the bottom surface of the outer shell at the lower end of the central tube.
[0015] This facilitates the positioning and installation of the lower end of the adsorption cylinder.
[0016] Furthermore, a sealing ring is provided at the upper end of the central tube.
[0017] This makes it easy to close the end cap, and ensures a sealed connection between the upper air tube and the central tube, preventing air leakage.
[0018] Furthermore, one end of the end cap is hinged to the outer shell, and a locking device is provided between the other end and the outer shell.
[0019] This makes it easy to open and lock the end cap.
[0020] Furthermore, the central tube vents and the outer shell vents are evenly distributed in the circumferential direction and layered in the height direction.
[0021] This allows for a more uniform loading of the catalytic adsorption material.
[0022] Therefore, the above-mentioned adsorption cylinder catalytic adsorption material loading processing equipment can efficiently, quickly, stably and uniformly load the adsorption cylinder with catalytic adsorption material. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] Example: An adsorption cylinder catalytic adsorption material loading and processing device, see [link to example]. Figures 1-2As shown, the device includes an outer shell 11 that is cylindrical in shape and has a depth greater than the height of the adsorption cylinder. The inner diameter of the outer shell 11 is greater than the outer diameter of the adsorption cylinder, and a central tube 12 is vertically fixed at the axial position. A pressure plate 13 is provided at the upper end of the central tube 12 corresponding to the height of the adsorption cylinder. The pressure plate 13 matches the shape of the upper end of the adsorption cylinder 6 and is used to press and fix the adsorption cylinder 6. A central tube air hole 14 is opened on the central tube 12. An end cap 15 is also provided at the upper end of the outer shell. An upper air pipe 16 is connected upward from the middle of the end cap 15. The lower end of the upper air pipe 16 passes through the end cap and connects with it after the end cap is closed. The central tube is connected to an upper air pipe 16, on which an upper fan 17 is installed. An upper feeding pipe with a switch valve is also connected to the upper air pipe between the upper fan and the end cap. The upper feeding pipe is connected to an upper feeding box 18. A hollow interlayer 24 is provided on the outer shell, and a lower air pipe 19 is connected to it. A lower fan 20 is installed on the lower air pipe. A lower feeding pipe with a switch valve is also connected to the lower air pipe between the lower fan 20 and the outer shell. The lower feeding pipe is connected to a lower feeding box 21. An outer shell air hole 22 communicating with the hollow interlayer is opened on the inner wall of the outer shell. Atomizing nozzles 23 are also provided on the outer wall of the central tube and the inner wall of the outer shell. The atomizing nozzles 23 are connected to a loading agent source (not shown in the figure) via a spray pipe.
[0027] In this way, when the processing equipment is working, first open the end cap, and insert the adsorption cylinder into the central tube layer by layer. Use a pressure plate to fix the adsorption cylinder and seal the upper port of the adsorption cylinder to complete the installation of the adsorption cylinder. Then close the end cap. First turn on the lower fan to guide the airflow, so that the inner cavity of the adsorption cylinder generates an outward negative pressure. Then turn on the atomizing nozzle on the outer wall of the central tube to spray the loading agent. The main component of the loading agent is a binder, which can evenly adhere to the inner wall of the adsorption cylinder under the action of negative pressure airflow. Then turn off the atomizing nozzle, and then add granular catalytic adsorption material through the upper feeding box. It enters the inner cavity of the adsorption cylinder with the negative pressure airflow through the upper feeding pipe and the central tube, and adheres and fixes to the inner wall of the adsorption cylinder under the action of negative pressure to complete the loading, forming a layer of catalytic adsorption material on the inner wall of the adsorption cylinder. Then, the lower fan is turned off and the upper fan is turned on to create an upward airflow negative pressure. The atomizing nozzle on the inner wall of the outer shell is opened, spraying out the loading agent, which adheres to the outer wall of the adsorption cylinder and the inner wall of the purification channel. Next, granular catalytic adsorption material is added through the lower feeding box, allowing it to enter the inner cavity of the outer shell through the lower feeding pipe and the hollow interlayer on the outer shell, carried by the negative pressure airflow. Under the action of negative pressure, it adheres and fixes to the outer wall of the adsorption cylinder and the inner wall of the purification channel, completing the loading process and forming a layer of catalytic adsorption material on the outer wall of the adsorption cylinder and the inner wall of the purification channel. During the loading process, under the upward airflow negative pressure, the inner end of the purification channel is the thinnest point inside and outside the adsorption cylinder. The inward airflow is strongest at this point, blowing away some of the inner layer of adsorption material previously loaded at this location. Therefore, after loading, the catalytic adsorption material at this location on the inner wall of the adsorption cylinder is relatively thin, naturally forming a weak area that allows gas to pass through. Alternatively, if the adsorption cylinder is 3D printed as a whole, the loading of the catalytic adsorption material can be completed using the aforementioned processing equipment after forming.
[0028] The pressure plate 13 is installed on the central tube 12 by means of a threaded connection.
[0029] This facilitates the loading and unloading of the pressure plate to enable the installation of the adsorption cylinder.
[0030] The lower end of the central tube 12 has a positioning cone 24 on the inner bottom surface of the outer shell facing upwards.
[0031] This facilitates the positioning and installation of the lower end of the adsorption cylinder.
[0032] A sealing ring 26 is provided at the upper end of the central tube 12.
[0033] This makes it easy to close the end cap, and ensures a sealed connection between the upper air tube and the central tube, preventing air leakage.
[0034] One end of the end cap 15 is hinged to the outer shell 11, and a locking device is provided between the other end and the outer shell.
[0035] This makes it easy to open and lock the end cap.
[0036] The central tube vent 14 and the outer shell vent 22 are both evenly distributed in the circumferential direction and layered in the height direction.
[0037] This allows for a more uniform loading of the catalytic adsorption material.
[0038] Therefore, the above-mentioned adsorption cylinder catalytic adsorption material loading processing equipment can efficiently, quickly, stably and uniformly load the adsorption cylinder with catalytic adsorption material.
