Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas purification technology, specifically a gas purification device. Background Technology
[0002] Gas purification refers to the process of removing impurities or pollutants from a gas mixture through physical, chemical, or biological methods to meet specific environmental, industrial, or health standards. It has a wide range of applications, including industrial emission control, indoor air quality improvement, and medical gas purification. In semiconductor manufacturing, gas purification is a core component of specialty gas systems.
[0003] However, most existing gas purification devices use filter screens and activated carbon plates to filter gases, which is difficult to fully remove various impurities contained in the gas. The interception effect of large particles in the impurities is poor, which can easily reduce the filtration efficiency of impurities in the gas and affect the purity of the purified gas. Utility Model Content
[0004] The purpose of this invention is to provide a gas purification device that, through the structural design of pipe joints, sintered metal felt, honeycomb ceramic membrane and zeolite, can effectively remove various impurities contained in the gas, thus solving the problem of the difficulty in effectively removing various impurities contained in the gas.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model is a gas purification device, including a box body. An air inlet pipe is embedded in one side plate of the box body and communicates with the interior of the box body. A mesh frame is set inside the box body, and zeolite is placed inside the mesh frame. An annular groove is opened in the inner circle of one end of the air inlet pipe. A honeycomb ceramic membrane, a metal sintered felt and a pipe joint are arranged in sequence from left to right in the annular groove. One end of the pipe joint is in contact with the surface of the metal sintered felt, and the end of the pipe joint away from the metal sintered felt is located outside the end of the honeycomb ceramic membrane.
[0007] Furthermore, a through hole is provided on one side panel of the housing, and the outer surface of the end of the air intake pipe away from the pipe joint is matched with the through hole.
[0008] Furthermore, a base is provided at the bottom of the box, and two diagonal braces are provided at the bottom of the air intake pipe, with the bottom ends of the two diagonal braces connected to the surface of the base.
[0009] Furthermore, a push ring is provided on the metal sintered felt, with one end of the push ring contacting one end of the honeycomb ceramic membrane.
[0010] Furthermore, two guide grooves are provided in the annular groove, and a locking groove is provided in the guide groove. Two locking blocks are provided on the outer surface of the pipe joint. The locking blocks cooperate with the guide grooves and the locking blocks engage with the locking grooves. A movable ring is provided in the annular groove.

Six compression springs are provided on the side of the movable ring away from the honeycomb ceramic membrane. One end of the six movable rings is connected to the inner wall of the annular groove.
[0011] Furthermore, the top of the box is provided with a cover plate, and a through groove is opened on the cover plate. An air outlet pipe is fitted in the through groove and is connected to the inside of the box.
[0012] This utility model has the following beneficial effects:
[0013] 1. This utility model, through the structural design of pipe joints, sintered metal felt, honeycomb ceramic membrane and zeolite, enables the gas to be fully purified after passing through the triple filtration of sintered metal felt, honeycomb ceramic membrane and zeolite in sequence. This can effectively remove various impurities contained in the gas, improve the interception effect of large particles in the impurities, improve the filtration efficiency of impurities in the gas, and ensure the purity of the purified gas.
[0014] 2. This utility model, through the structural design of locking blocks, movable rings, and compression springs, achieves rapid removal of the metal sintered felt and honeycomb ceramic membrane within the ring groove by separating the two locking blocks from their corresponding slots and the rebound force of the six compression springs pushing the movable ring to slide within the ring groove. This allows for convenient installation and disassembly of the metal sintered felt and honeycomb ceramic membrane, effectively shortening the installation and disassembly time, reducing the difficulty of installation and disassembly, simplifying operation, saving effort, and greatly improving the maintenance efficiency of the device.

[0021] 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.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a gas purification device, including a housing 1, a cover plate on the top of the housing 1, a through groove on the cover plate, an outlet pipe 101 in the through groove, the outlet pipe 101 communicating with the interior of the housing 1, which can conveniently discharge purified gas, an inlet pipe 2 embedded in one side plate of the housing 1, a through hole on one side plate of the housing 1, the outer surface of the end of the inlet pipe 2 away from the pipe connector 3 mates with the through hole, which can conveniently connect the inlet pipe 2 to the housing 1, a base at the bottom of the housing 1, two diagonal braces at the bottom of the inlet pipe 2, the bottom ends of the two diagonal braces are connected to the surface of the base, which can support the inlet pipe 2 and ensure the stable installation of the inlet pipe 2, the inlet pipe 2 communicating with the interior of the housing 1, a mesh frame 7 is provided inside the housing 1, and zeolite 8 is placed in the mesh frame 7, which can conveniently and selectively adsorb impurities such as H2O, CO2, and small molecule gases, so that the gas is fully purified.
[0023] An annular groove 201 is provided on the inner ring of one end of the intake pipe 2. From left to right, a honeycomb ceramic membrane 5, a metal sintered felt 4, and a pipe connector 3 are arranged in the annular groove 201. One end of the pipe connector 3 is in contact with the surface of the metal sintered felt 4. A push ring 401 is provided on the metal sintered felt 4. One end of the push ring 401 is in contact with one end of the honeycomb ceramic membrane 5, which can facilitate the honeycomb ceramic membrane 5 to push the metal sintered felt 4 to slide in the annular groove 201. The end of the pipe connector 3 away from the metal sintered felt 4 is located on the outer side of one end of the honeycomb ceramic membrane 5, which can facilitate connection with the external gas transmission pipeline.
[0024] During gas purification, the gas delivery pipeline is connected to the pipe connector 3. After the gas enters the inlet pipe 2 through the pipe connector 3, it passes through the sintered metal felt 4, where the sintered metal felt 4 intercepts and filters large particulate impurities in the gas. The gas then passes through the sintered metal felt 4 and enters the honeycomb ceramic membrane 5. Through the honeycomb structure on the honeycomb ceramic membrane 5, the gas makes full contact with the interior of the honeycomb ceramic membrane 5, allowing the honeycomb ceramic membrane 5 to quickly adsorb and filter the tiny impurities in the gas. This significantly reduces the impurity content in the gas. Then, the gas enters the chamber 1 through the inlet pipe 2 and passes through the zeolite 8 filled in the mesh frame 7. The zeolite 8 selectively adsorbs impurities such as H2O, CO2, and small molecule gases in the gas, thereby effectively filtering the impurities and achieving thorough purification of the gas.
[0025] Two guide grooves 202 are provided in the annular groove 201, and a slot 203 is provided in the guide groove 202. Two locking blocks 301 are provided on the outer surface of the pipe connector 3. The locking blocks 301 cooperate with the guide grooves 202 and are engaged with the slots 203. A movable ring 6 is provided in the annular groove 201. One side of the movable ring 6 contacts the end of the honeycomb ceramic membrane 5 away from the metal sintered felt 4. Six compression springs 601 are provided on the side of the movable ring 6 away from the honeycomb ceramic membrane 5. One end of the six movable rings 6 is connected to the inner wall of the annular groove 201. A damping pad is provided on one end of the compression spring 601. One side of the damping pad is connected to the inner wall of the annular groove 201, which can ensure that the compression spring 601 contracts and rebounds stably in the annular groove 201.
[0026] When the sintered metal felt 4 and honeycomb ceramic membrane 5 inside the intake pipe 2 require maintenance and cleaning after prolonged use, rotate the pipe connector 3 counterclockwise. This causes the two locking blocks 301 on the pipe connector 3 to separate from their corresponding slots 203. Continue rotating the pipe connector 3 until the two locking blocks 301 are fully inserted into their corresponding guide slots 202. Then, stop rotating the pipe connector 3 and remove it from the annular groove 201. At this point, the locking effect of the locking blocks 301 disappears. The rebound force generated by the compression of the six compression springs 601 on the movable ring 6 causes the rebound force of the six compression springs 601 to pass through the movable ring 6. The honeycomb ceramic membrane 5 is pushed to slide within the annular groove 201, causing it to contact the push ring 401 and push the metal sintered felt 4 towards the outside of the annular groove 201. This causes the metal sintered felt 4 to pop out of the annular groove 201. After removing the metal sintered felt 4, the honeycomb ceramic membrane 5 is then removed from the annular groove 201, thus achieving convenient removal of the metal sintered felt 4 and the honeycomb ceramic membrane 5. Similarly, when it is necessary to return the metal sintered felt 4 to the annular groove 201, the above operation is repeated in reverse order, thus achieving rapid installation of the metal sintered felt 4 and the honeycomb ceramic membrane 5.
[0027] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
