Description

Technical Field

[0001] This utility model relates to the field of gas impurity removal technology, and more specifically, to an industrial gas impurity removal device. Background Technology

[0002] Industrial gas purification refers to the process of removing unwanted impurities from raw materials, process gases, or product gases in industrial production. Its purpose is to purify the gas to meet the purity, safety, and quality requirements of specific applications. In the continuous process of industrial production, raw gas is continuously produced from the previous process (such as gasifier, fermenter, reactor) and needs to be purified immediately before entering the next process. Therefore, the purification operation is carried out directly in the pipeline transporting the raw gas, without intermediate storage and transfer, ensuring seamless connection and maximum efficiency of the production process. Currently, pipelines transporting industrial gases are closed structures, while the filtration and impurity removal mechanisms are located inside the pipelines. This requires frequent shutdowns for cleaning, which involves a large workload. In addition, some hazardous gases may leak out during shutdowns for cleaning, posing a safety hazard. To address the aforementioned problems, this application proposes an industrial gas purification device. Utility Model Content

[0003] The purpose of this invention is to provide an industrial gas purification device to solve the problems in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: An industrial gas impurity removal device includes a gas transmission pipe and a transfer pipe at its end, with impurity removal pipes connected between adjacent transfer pipes; The impurity removal mechanism is installed inside the impurity removal tube and includes a fixing frame, the outer layer of which is made of rubber. The fixed frame has a conical guide frame and a conical filter screen at the entrance, which are staggered left and right. The conical guide frame is a solid structure. An airflow channel is formed on the outer side of the conical guide frame. A storage cylinder extends to the right from the center of the conical filter screen. A screen is fixed inside the junction of the conical filter screen and the storage cylinder. A fixing plate is fixed on the right side of the conical guide frame to form a closed space. A rotary motor is built in the space, and a pressure plate is fixed at one end of its rotating shaft to press impurities against the screen. The storage cylinder is fixed to the right end with a discharge pipe, which is connected to the protruding pipe at the upper end of the discharge pipe.

[0005] Preferably, the two ends of the impurity removal tube are provided with an inner tube and an outer tube with inner and outer layers. The inner tube is attached to the inner wall of the transfer tube, and the inner side of the outer tube is spirally connected to the transfer tube.

[0006] Preferably, a connecting pipe is fixedly installed at the upper end of the tapered guide frame, which is connected to the second protrusion at the upper end of the impurity removal pipe. The connecting pipe is used to pass through the wires to connect the rotary motor.

[0007] Preferably, the outer side of the conical guide frame is provided with multiple ring frames, and an annular channel is formed between adjacent ring frames.

[0008] Preferably, a fixing rod is fixed to the outer side of the tapered guide frame, and is fixedly connected to the ring frame and the fixing frame.

[0009] Preferably, a scraper is provided on the outer side of the rotating shaft of the rotary motor, and is fixedly connected by a connecting rod on the side of the scraper. A scraper blade extends from one side of the scraper and fits against the inner side of the conical filter screen.

[0011] Preferably, a connecting rod is fixedly installed on the outer side of the storage cylinder, with its end connected to the inner wall of the fixed frame.

[0012] The beneficial effects of this utility model are: 1. Through the bidirectional guidance of the conical guide frame and the conical filter screen, the gas enters the outer ring area and passes through the conical filter screen. The continuous gas output guides the impurities intercepted by the conical filter screen to gather in the inner ring area and into the storage cylinder, thereby forming a self-cleaning effect. This achieves the effect of long-term impurity removal without frequent manual cleaning. 2. The scraping of the screen by the pressure plate causes impurities to pass through the screen and be sucked out by the impurity discharge pipe, thereby achieving the separation of impurities and industrial gas. After the impurities are automatically collected, they are discharged through the branch line, which not only further maintains the self-cleaning effect, but also avoids safety accidents such as gas leakage caused by manual cleaning.

[0015] 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.

[0016] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] An industrial gas impurity removal device is designed to remove impurities from industrial gases in real time. It forms a bidirectional guide with a conical guide frame 42 and a conical filter screen 43, which can both intercept impurities and promote their accumulation in the central storage cylinder 44. Then, the pressure plate 46 presses the impurities into the interior of the storage cylinder 44 and extracts them through the impurity discharge pipe 441 (the impurity discharge pipe 441 is connected to an external vacuum pump via a convex pipe 33 to achieve the suction effect), thus forming a diversion. This enables long-term automatic cleaning of impurities and prevents the risk of gas leakage from manual cleaning. In some embodiments, the specific structure of the industrial gas purification device is as follows: Figure 1-6 As shown, it includes a gas transmission pipe 1, a transfer pipe 2, and a debris removal pipe 3; The impurity removal pipe 3 is connected to the gas transmission pipe 1 as a whole through the adapter pipes 2 at both ends; One end of the transfer pipe 2 has a flared structure and is fitted onto the outside of the gas transmission pipe 1; The other end of the adapter pipe 2 has a threaded structure on the outside, which is spirally connected to the inner side of the outer tube 32 of the outer ring at the end of the impurity removal pipe 3. The inner tube 31 of the inner ring at the end of the impurity removal pipe 3 fits against the inner wall of the adapter pipe 2 to form a seal. The impurity removal mechanism 4 has a fixed frame 41 as its main body, located inside the impurity removal pipe 3. A left and right conical guide frame 42 and a conical filter screen 43 are installed in the inlet area. Among them, the cone point of the cone-shaped guide frame 42 is on the left, and the cone point of the cone-shaped filter screen 43 is on the right; It is understandable that the conical guide frame 42 guides the gas and impurities to the outer ring and then into the area where the conical filter screen 43 is located, where they are guided a second time. The subsequent gas uses a thrust to push the intercepted impurities towards the inner ring area. A storage cylinder 44 is fixed at the center of the conical filter screen 43, located in the right end area; Among them, a screen 431 is fixedly installed on the center line of the conical filter screen 43, located at the inlet of the storage cylinder 44; Furthermore, a rotary motor is installed at the rear of the tapered guide frame 42, and a pressure plate 46 is fixedly installed at the end of its rotating shaft to press the impurities on the mesh and surface of the screen 431 into the interior of the storage cylinder 44. Furthermore, a waste discharge pipe 441 is fixedly installed at the other end of the storage cylinder 44, which is connected to the protrusion 33 at the upper end of the waste removal pipe 3; Understandably, the screen 431 intercepts the impurities that are guided towards the inner circle and is pressed into the interior of the storage cylinder 44 by the pressure plate 46. Then, through the discharge pipe 441 and the external suction pipe of the convex pipe 33, a branch for the discharge of impurities is formed.

[0018] like Figure 2 and Figure 3 As shown, a fixing plate 422 is fixed to the right end of the tapered guide frame 42, and a cavity for installing the rotary motor is formed between the two. Among them, the upper end of the tapered guide frame 42 is fixed with a connecting pipe 4212, which is connected to the inside of the convex pipe 34 at the upper end of the impurity removal pipe 3; Understandably, the connecting pipe 4212 is used to run wires so that the rotating motor can be electrically connected to external equipment; It should be noted that the outer body of the fixing frame 41 is made of elastic silicone rubber material, which can automatically form a seal against the inner wall of the impurity removal tube 3.

[0019] like Figure 3 As shown, the outer layer of the conical guide frame 42 is provided with multiple ring frames 421, and a fixing rod 4211 is fixedly connected between the conical guide frame 42 and the ring frames 421. One end of the fixing rod 4211 is connected to the fixing frame 41. Among them, airflow channels are formed between adjacent annular frames 421 to expand the guided and reduced flow area.

[0020] like Figure 3 and Figure 4 as well as Figure 5 As shown, the inner side of the conical filter screen 43 is provided with multiple scrapers 45, which are evenly distributed around the rotating shaft of the rotary motor. Among them, a scraper blade 451 extends out from one side of the scraper 45 and is attached to the conical filter screen 43 to scrape off impurities and prevent long-term adsorption. Furthermore, a connecting rod 452 is fixed to one side of the scraper 45, and one end of the connecting rod 452 is fixedly connected to the rotating shaft.

[0021] like Figure 4 and Figure 6 As shown, the pressure plate 46 includes a guide plate 461 and a pressure plate 462; Among them, the guide plate 461 is attached to the screen 431, and the pressing plate 462 is raised outward to guide the impurities adsorbed on the screen 431, so that they enter between the screen 431 and the guide plate 461, and are squeezed through the screen 431 into the interior of the storage cylinder 44. Furthermore, a connecting rod 442 is fixed to the outside of the storage cylinder 44, with one end connected to the inner wall of the fixing frame 41.

[0022] It should be noted that the fixing frame 41 is an annular cylindrical structure. Through the elastic deformation of the outer layer of silicone rubber material, it can be directly inserted into the interior of the impurity removal pipe 3, so that the impurity discharge pipe 441 and the connecting pipe 4212 are respectively connected to the convex pipe 33 and convex pipe 34 at the upper end of the impurity removal pipe 3 to form positioning and fixation.

[0023] Some publicly available information describes the specific usage methods of industrial gas purification devices as follows: S1. After the adapter pipe 2 and the outer pipe 32 are screwed together to form an integral unit, the adapter pipe 2 is sleeved on the end of the gas transmission pipe 1, so that the gas transmission pipe 1, the adapter pipe 2 and the impurity removal pipe 3 are connected as one unit. S2. When the gas passes through the impurity removal pipe 3, it is first blocked by the conical guide frame 42 and guided to flow in the outer ring area. During this process, it passes through the through slots between adjacent annular frames 421 in layers. S3. Gas enters the area where the conical filter 43 is located. The gas passes through the conical filter 43 continuously. Impurities in the gas are intercepted by the conical filter 43. With the continuous transmission of subsequent gas, a thrust is formed on the impurities, causing them to move towards the central area. S4. The rotating motor between the conical guide frame 42 and the ring frame 421 scrapes the conical filter screen 43 through the scraper 45 on the outside of its rotating shaft, so that the impurities fall off in time and gather in the central area under the push of the subsequent gas, and are finally intercepted by the screen 431. S5. The guide plate 461 on the outside of the rotating shaft guides the impurities, and then the pressure plate 462 squeezes the impurities, so that the impurities pass through the screen 431 and enter the interior of the storage cylinder 44, and are finally sucked out by the impurity discharge pipe 441 to form a branch flow.
