Description

Technical Field

[0001] This application relates to the technical field of air purification treatment, and particularly to an air odor purification treatment device for the end air outlet of a high-precision laboratory. Background Art

[0002] With the continuous improvement of the requirements for air cleanliness and gas component stability in high-precision experimental environments, air purification equipment has become a key component of the laboratory air treatment system. To ensure indoor air quality, existing technologies usually set up multi-stage filtration units at the intake end, such as primary, intermediate, and high-efficiency filters, and set up treatment devices for removing odors and harmful gases at the exhaust end.

[0003] During actual use, the treatment device at the exhaust end often adopts a series-connected split structure and is fixedly installed in the air duct. Once a certain module needs maintenance, replacement, or fault repair, the entire system often needs to be shut down, resulting in the interruption of the entire air treatment system and seriously affecting the continuous operation of the laboratory. Summary of the Invention

[0004] In order to achieve non-stop maintenance of the gas treatment device at the tail end of the laboratory exhaust and still have a gas treatment effect during maintenance to ensure the continuous progress of the experiment, this application provides an air odor purification treatment device for the end air outlet of a high-precision laboratory.

[0005] An air odor purification treatment device for the end air outlet of a high-precision laboratory provided by this application adopts the following technical solutions: A high-precision air odor purification and treatment device for the end air outlet of a laboratory, comprising a housing, a first ionic oxygen air purifier, a first activated carbon adsorption module and a first photocatalytic oxidation purifier. A main air duct and a bypass air duct are arranged in the housing. The first ionic oxygen air purifier, the first activated carbon adsorption module and the first photocatalytic oxidation purifier are arranged in sequence along the exhaust air direction and are respectively installed in the main air duct through a drawing component. A second ionic oxygen air purifier, a second activated carbon adsorption module and a second photocatalytic oxidation purifier are sequentially arranged in the bypass air duct along its exhaust air direction. The drawing component is connected with an opening and closing component, and the opening and closing component is arranged in the bypass air duct. The three drawing components are respectively used for drawing / inserting the first ionic oxygen air purifier, the first activated carbon adsorption module and the first photocatalytic oxidation purifier into / from the housing. The three opening and closing components are respectively used for closing / opening the intake end and the exhaust end of the second ionic oxygen air purifier, the intake end and the exhaust end of the second activated carbon adsorption module, and the exhaust end and the exhaust end of the second photocatalytic oxidation purifier. When the drawing component is in the drawn state, the drawing component drives the opening and closing component to open the corresponding part of the bypass air duct of the drawing component, and the opening and closing component closes the corresponding part of the main air duct of the drawing component. The bypass air duct is provided with a first ventilation opening and a second ventilation opening. The first ventilation opening is located between the first ionic oxygen air purifier and the first activated carbon adsorption module, and the second ventilation opening is located between the first activated carbon adsorption module and the first photocatalytic oxidation purifier.

[0006] By adopting the above technical solution, during normal operation, the gas sequentially passes through the first ionic oxygen air purifier, the first activated carbon adsorption module and the first photocatalytic oxidation purifier. The first ionic oxygen air purifier plays a role in quickly removing odors and killing microorganisms. The first activated carbon adsorption module further adsorbs and purifies residual molecules and non-polar organic substances. Since the first activated carbon adsorption module is prone to saturation, the first photocatalytic oxidation purifier continuously decomposes the unadsorbed molecules to ensure the purification effect of the gas.

[0007] When it is necessary to replace the first ion-oxygen air purifier, the corresponding pulling component is extracted. The pulling component simultaneously drives the corresponding opening and closing component to start. The opening and closing component closes part of the main air duct corresponding to the first ion-oxygen air purifier, and at the same time, the opening and closing component opens the bypass air duct part corresponding to the second ion-oxygen air purifier. The gas can first enter the bypass air duct, pass through the second ion-oxygen air purifier, and then be discharged into the main air duct from the first ventilation opening, and then pass through the first activated carbon adsorption module and the first photocatalytic oxidation purifier. At this time, the first ion-oxygen air purifier can be disassembled from the corresponding pulling component and replaced. After the replacement is completed, the pulling component is re-inserted into the housing, and the corresponding opening and closing component closes the corresponding parts of the bypass air duct (i.e., the intake end and the exhaust end of the second ion-oxygen air purifier) again, and opens the corresponding parts of the main air duct (i.e., the intake end and the exhaust end of the first ion-oxygen air purifier).

[0008] And so on. When replacing the first activated carbon adsorption module, the gas passes through the first ion-oxygen air purifier, the second activated carbon adsorption module and the first photocatalytic oxidation purifier in sequence. When replacing the first photocatalytic oxidation purifier, the gas passes through the first ion-oxygen air purifier, the first activated carbon adsorption module and the second photocatalytic oxidation purifier in sequence.

[0009] It realizes the gas treatment device at the tail gas end of the laboratory without shutting down the machine for maintenance, and still has the gas treatment effect during maintenance, ensuring the continuous progress of the experiment. Multiple units are integrally installed in the same housing, replacing the design of setting multiple independent installation positions in the traditional structure. Only one overall installation opening needs to be opened in the system air duct, avoiding the problem that the opening of multiple small installation openings easily weakens the structure of the air duct wall, resulting in cracks or deformation during long-term use, which is beneficial to maintaining the integrity and strength of the overall structure of the air duct.

[0010] Moreover, it avoids all airflows bypassing into the complete bypass during switching during maintenance, and avoids relying on all units of the bypass to bear all the purification burdens; therefore, the design of this technical solution can achieve that during repair, other main path processing units still work normally, and only a single unit is temporarily downgraded for processing, reducing the impact on the overall tail gas treatment effect.

[0011] Optionally, the pulling component includes a pulling seat. The housing is provided with installation openings corresponding to the pulling seats one by one. The pulling seat is provided with an insertion opening, and a pulling plate is installed in the insertion opening. The first ion-oxygen air purifier and the first photocatalytic oxidation purifier are installed on the corresponding pulling plates. The first ion-oxygen air purifier, the first activated carbon adsorption module and the first photocatalytic oxidation purifier can be inserted into the housing through the corresponding insertion openings. The pulling seat is connected to the opening and closing component through a connecting piece.

[0012] By adopting the above technical solution, when replacing the first ion oxygen air purifier, the draw-out seat is pulled out of the housing. The draw-out seat drives the connecting member to control the opening and closing assembly to close the main air duct part where the first ion oxygen air purifier is located. At the same time, the opening and closing assembly opens the bypass air duct part where the second ion oxygen air purifier is located. Then, the draw-out plate is separated from the draw-out seat, and the draw-out plate and the first ion oxygen air purifier are separated from the draw-out seat.

[0013] Similarly, for the replacement of the first activated carbon adsorption module and the first photocatalytic purifier, only the corresponding draw-out seat and draw-out plate need to be pulled out in sequence.

[0014] Optionally, the connecting member includes a sliding plate. The sliding plate is supported on the inner bottom wall of the housing and is slidably connected to the housing. A connecting plate is installed at one end of the sliding plate away from the draw-out seat. When the connecting plate abuts against the inner wall of the main air duct facing the draw-out seat, the draw-out seat is located within the installation opening, and the connecting plate is connected to the opening and closing assembly.

[0015] By adopting the above technical solution, the sliding plate is slidably connected to the housing, enabling the draw-out seat to be stably pulled out of the housing. The connecting plate is connected to the opening and closing assembly. When the connecting plate moves, the connecting plate drives the opening and closing assembly to move. And when the connecting plate abuts against the inner wall of the housing facing the draw-out seat, it indicates that the draw-out seat has been inserted in place. When the connecting plate abuts against the inner wall of the housing away from the draw-out seat, it indicates that the opening and closing assembly has opened the corresponding bypass air duct part and closed the corresponding main air duct part.

[0016] Optionally, a plug pin is connected to the connecting plate. A slot is formed on the inner side wall of the housing facing the connecting plate. A clamping groove is formed on the plug pin. A clamping rod is arranged inside the housing. The clamping rod is provided with a guiding surface. A spring is connected to the clamping rod. The plug pin can be inserted into the slot, and the clamping rod can be inserted into the clamping groove. An electromagnet is commonly installed at one end of the clamping rod away from the slot and the housing.

[0017] By adopting the above technical solution, when the draw-out seat is pulled in place, the plug pin is inserted into the slot. And during the process of the plug pin being inserted into the slot, it acts on the guiding surface, causing the clamping rod to first move away from the plug pin and then be inserted into the clamping groove, realizing the automatic locking of the draw-out seat, avoiding the sliding of the draw-out seat during maintenance, which affects the installation of the first ion oxygen air purifier, the first activated carbon adsorption module, and the first photocatalytic oxidation purifier, and also avoiding causing the opening and closing assembly to open the main air duct, thereby resulting in gas leakage.

[0018] When it is necessary to push the draw-out seat back into the housing again, the electromagnet is activated. The electromagnet drives the clamping rod away from the slot, so that the plug pin can be disengaged from the slot, enabling the draw-out seat to be pushed back into the housing again.

[0019] Optionally, the first activated carbon adsorption module is installed on the corresponding pull-out plate through a mounting member.

[0020] By adopting the above technical solution, the first activated carbon adsorption module is detachably connected to the pull-out plate through the mounting member, rather than directly pushing the first activated carbon adsorption module into the pull-out seat. This helps prevent activated carbon particles from directly falling on the pull-out plate, thereby reducing the residue of activated carbon particles in the housing.

[0021] Optionally, the mounting member includes a connecting block. The connecting block is installed on the corresponding pull-out plate. When the pull-out plate connected to the connecting block is located in the corresponding insertion opening, the support plate supports on the corresponding sliding plate. At one end of the support plate away from the connecting block, two limiting rods are installed. The two limiting rods are L-shaped and arranged oppositely. When the first activated carbon adsorption module is located on the support plate, two corners of the first activated carbon adsorption module are respectively located in the depressions of the two limiting rods.

[0022] By adopting the above technical solution, the pull-out plate drives the connecting block to move, so that the support plate and the limiting rods drive the first activated carbon adsorption module to separate from the pull-out seat, and the limiting rods and the connecting block play a role in limiting the front end and the rear end of the first activated carbon adsorption module.

[0023] Optionally, one end of the pull-out seat inserted into the installation opening is adapted to the installation opening, and a sealing gasket is arranged along the circumferential direction of the pull-out seat at the end inserted into the installation opening. At least one group of abutting plates is hinged on the side of the pull-out seat away from the installation opening. The number of each group of abutting plates is two and they are respectively located on one side of the pull-out seat. A strip-shaped hole is opened in the abutting plate. A tightening bolt is hinged on the housing. The tightening bolt is connected with a strip-shaped block. When the strip-shaped block is in the same length direction as the strip-shaped hole, the strip-shaped block can pass through the strip-shaped hole.

[0024] By adopting the above technical solution, after the pull-out seat is inserted into the installation opening, the abutting plate is flipped to make the strip-shaped hole pass through the strip-shaped block, and then when the strip-shaped block is rotated, the strip-shaped block presses the abutting plate, thereby realizing the fixation of the pull-out seat in the housing, which is convenient for installation and fixation. At the same time, the sealing gasket plays a sealing role to reduce the leakage of gas in the housing from the installation opening.

[0025] Optionally, a first replacement opening, a second replacement opening and a third replacement opening are opened at the bottom of the housing. The second ionic oxygen air purifier is installed in the side air duct through the first replacement opening, the second activated carbon adsorption module is installed in the side air duct through the second replacement opening, and the second photocatalytic oxidation purifier is installed in the side air duct through the third replacement opening.

[0026] By adopting the above technical solution, the settings of the first replacement port, the second replacement port and the third replacement port facilitate the replacement of the second ionic oxygen air purifier, the second activated carbon adsorption module and the second photocatalytic oxidation purifier.

[0027] Optionally, the opening and closing assembly includes two fixed sleeves, the fixed sleeves are arranged in the side air duct, air vents are formed in the circumferential surface of the fixed sleeves, a secondary telescopic member is installed in the fixed sleeves, the secondary telescopic member can pass through the side air duct and block the main air duct, and the secondary telescopic member is connected to the pulling assembly.

[0028] By adopting the above technical solution, during normal operation, the secondary telescopic member is located in the fixed sleeve, the secondary telescopic member closes the air vent, so that the corresponding part of the side air duct is in a closed state. When maintenance and replacement are required, the pulling assembly drives the secondary telescopic member to move. When the secondary telescopic member completely extends, the secondary telescopic member extends into the main air duct to block the corresponding part of the main air duct, while the air vent is opened, so that the corresponding part of the side air duct is opened.

[0029] Optionally, the secondary telescopic member includes a sliding sleeve plate. The fixed sleeve is provided with a first sliding groove along its length direction. The sliding sleeve plate is connected with a first limiting block, and the first limiting block is slidably arranged in the first sliding groove. The sliding sleeve plate is sleeved in the fixed sleeve and fits with the inner wall of the fixed sleeve. A second sliding groove is formed in the sliding sleeve plate, a sliding plate is inserted into the sliding sleeve plate, and the sliding plate is connected with a second limiting block, and the second limiting block is slidably arranged in the second sliding groove.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: 1. During normal operation, the gas sequentially passes through the first ionic oxygen air purifier, the first activated carbon adsorption module and the first photocatalytic oxidation purifier. The first ionic oxygen air purifier plays a role in quickly removing odors and killing microorganisms. The first activated carbon adsorption module further adsorbs and purifies residual molecules and non-polar organic substances. Since the first activated carbon adsorption module is prone to saturation, the first photocatalytic oxidation purifier continuously decomposes the unadsorbed molecules to ensure the purification effect of the gas; 2. It realizes the maintenance of the gas treatment device at the tail end of the laboratory exhaust gas without stopping the machine, and still has the gas treatment effect during maintenance, ensuring the continuous progress of the experiment. Multiple units are integrally installed in the same housing, replacing the design of separately setting multiple independent installation positions in the traditional structure. Only one overall installation opening needs to be opened in the system air duct, avoiding the problem that the opening of multiple small installation openings easily weakens the wall structure of the air duct, resulting in cracks or deformation during long-term use, which is beneficial to maintaining the integrity and strength of the overall structure of the air duct; 3. It avoids all airflows from bypassing into the complete bypass during maintenance, and avoids relying on all units of the bypass to bear the entire purification burden. Therefore, the design of this technical solution can ensure that during repair, other main path processing units still operate normally, and only a single unit is temporarily downgraded for processing, reducing the impact on the overall effect of tail gas treatment.

[0039] The following further describes the present application in detail Figure 1-7 in conjunction with the attached drawings.

[0040] An embodiment of the present application discloses an air odor purification and treatment device for the end air outlet of a high-precision laboratory.

[0041] As Figure 1 shown in Figure 2 FIGs.

[0042] As Figure 2 shown in Figure 3, the bottom of the housing 1 is successively provided with a first replacement opening 16, a second replacement opening 17, and a third replacement opening 18 along its length direction. The first replacement opening 16, the second replacement opening 17, and the third replacement opening 18 are communicated with the side air duct 14. A second ion oxygen air purifier 34 is installed in the side air duct 14 through the first replacement opening 16, a second activated carbon adsorption module 35 is installed in the side air duct 14 through the second replacement opening 17, and a second photocatalytic oxidation purifier 36 is installed in the side air duct 14 through the third replacement opening 18. Moreover, the first ion oxygen air purifier 31 and the second ion oxygen air purifier 34 are arranged along the width direction of the housing 1, the first photocatalytic oxidation purifier 33 and the second photocatalytic oxidation purifier 36 are arranged along the width direction of the housing 1, and the first activated carbon adsorption module 32 and the second activated carbon adsorption module 35 are arranged along the width direction of the housing 1.

[0043] Each of the three drawing components 2 is connected with an opening and closing component 5. The opening and closing component 5 is arranged in the side air duct 14. The three drawing components 2 are respectively used for drawing / inserting the first ion oxygen air purifier 31, the first activated carbon adsorption module 32, and the first photocatalytic oxidation purifier 33 into / from the housing 1; The opening and closing component 5 near the air inlet is used for opening and closing the corresponding parts of the side air duct 14 at the air inlet end and the air outlet end of the second ion oxygen air purifier 34, and for opening and closing the corresponding parts of the main air duct 13 at the air inlet end and the air outlet end of the first ion oxygen air purifier 31; The opening and closing component 5 located in the middle of the housing 1 is used for opening and closing the corresponding parts of the side air duct 14 at the air inlet end and the air outlet end of the second activated carbon adsorption module 35, and for opening and closing the corresponding parts of the main air duct 13 at the air inlet end and the air outlet end of the first activated carbon adsorption module 32; The opening and closing component 5 near the air outlet is used for opening and closing the corresponding parts of the exhaust air duct at the air outlet end of the second photocatalytic oxidation purifier 36 and the air outlet end, and for opening and closing the corresponding parts of the main air duct 13 at the air inlet end and the air outlet end of the first photocatalytic oxidation purifier 33.

[0044] The three drawing components 2 are respectively used for drawing / inserting the first ion oxygen air purifier 31, the first activated carbon adsorption module 32, and the first photocatalytic oxidation purifier 33 into / from the housing 1. When the drawing component 2 is in the drawn state, the drawing component 2 drives the opening and closing component 5 to open the corresponding part of the side air duct 14, and the opening and closing component 5 closes the corresponding part of the main air duct 13. The side air duct 14 is provided with a first ventilation opening 19 and a second ventilation opening 110. The first ventilation opening 19 is located between the first ion oxygen air purifier 31 and the first activated carbon adsorption module 32, and the second ventilation opening 110 is located between the first activated carbon adsorption module 32 and the first photocatalytic oxidation purifier 33.

[0045] During normal operation, the gas passes through the first ionic oxygen air purifier 31, the first activated carbon adsorption module 32, and the first photocatalytic oxidation purifier 33 in sequence. The first ionic oxygen air purifier 31 plays a role in quickly removing odors and killing microorganisms. The first activated carbon adsorption module 32 further adsorbs and purifies residual molecules and non-polar organic compounds. Since the first activated carbon adsorption module 32 is prone to saturation, the first photocatalytic oxidation purifier 33 continuously decomposes the unadsorbed molecules to ensure the purification effect of the gas.

[0046] When the first ionic oxygen air purifier 31 needs to be replaced, the corresponding drawer assembly 2 is pulled out. The drawer assembly 2 simultaneously drives the corresponding opening and closing assembly 5 to start. The opening and closing assembly 5 partially closes the main air duct 13 corresponding to the first ionic oxygen air purifier 31. At the same time, the opening and closing assembly 5 opens the bypass air duct 14 corresponding to the second ionic oxygen air purifier 34. The gas can first enter the bypass air duct 14, pass through the second ionic oxygen air purifier 34, and then be discharged into the main air duct 13 from the first ventilation opening 19, and then pass through the first activated carbon adsorption module 32 and the first photocatalytic oxidation purifier 33. At this time, the first ionic oxygen air purifier 31 can be removed from the corresponding drawer assembly 2 and replaced. After the replacement is completed, the drawer assembly 2 is reinserted into the housing 1, and the corresponding opening and closing assembly 5 closes the corresponding parts of the bypass air duct 14 (i.e., the inlet and outlet ends of the second ionic oxygen air purifier 34) again, and opens the corresponding parts of the main air duct 13 (i.e., the inlet and outlet ends of the first ionic oxygen air purifier 31).

[0047] And so on. When the first activated carbon adsorption module 32 is replaced, the gas passes through the first ionic oxygen air purifier 31, the second activated carbon adsorption module 35, and the first photocatalytic oxidation purifier 33 in sequence. When the first photocatalytic oxidation purifier 33 is replaced, the gas passes through the first ionic oxygen air purifier 31, the first activated carbon adsorption module 32, and the second photocatalytic oxidation purifier 36 in sequence.

[0048] It realizes the gas treatment device at the tail end of the laboratory without stopping the machine for maintenance, and still has the gas treatment effect during maintenance, ensuring the continuous progress of the experiment. Multiple units are integrally installed in the same housing 1, replacing the design of separately setting multiple independent installation positions in the traditional structure. Only one overall installation opening 15 needs to be opened in the system air duct, avoiding the problem that the opening of multiple small installation openings 15 easily weakens the structure of the air duct wall and causes cracks or deformation during long-term use, which is beneficial to maintaining the integrity and strength of the overall structure of the air duct.

[0049] Moreover, it avoids all airflows from bypassing into the complete bypass during maintenance, and avoids relying on all units of the bypass to bear the entire purification burden; therefore, the design of this technical solution can achieve that when repairing, other main path processing units still work normally, and only a single unit is temporarily degraded, reducing the impact on the overall tail gas treatment effect.

[0050] Such as Figure 3 , the pulling component 2 includes a pulling seat 21, the pulling seat 21 is T-shaped, an insertion opening 211 is formed in the middle of the pulling seat 21, a pulling plate 22 is bolted to the insertion opening 211, the first ionic oxygen air purifier 31 and the first photocatalytic oxidation purifier 33 are installed on the corresponding pulling plate 22, and the first ionic oxygen air purifier 31, the first activated carbon adsorption module 32 and the first photocatalytic oxidation purifier 33 can be inserted into the housing 1 through the corresponding insertion opening 211, and the pulling seat 21 is connected to the opening and closing component 5 through a connecting piece 23.

[0051] Such as Figure 4 and Figure 5 , the connecting piece 23 includes a sliding plate 231, the sliding plate 231 is supported on the inner bottom wall of the housing 1 and is slidably connected to the housing 1, a connecting plate 232 is installed at one end of the sliding plate 231 away from the pulling seat 21, when the connecting plate 232 abuts against the inner wall of the main air duct 13 facing the pulling seat 21, the pulling seat 21 is located in the installation opening 15, and the connecting plate 232 is connected to the opening and closing component 5.

[0052] A plug pin 24 is connected to the side of the connecting plate 232 facing the pulling seat 21, the number of the plug pins 24 is two and they are respectively located on both sides of the connecting plate 232, a slot 111 is formed on the inner side wall of the housing 1 facing the connecting plate 232, the slot 111 corresponds to the plug pin 24 one by one, a clamping groove 241 is formed in the plug pin 24, a clamping rod 25 is slidably arranged in the housing 1, a guiding surface 251 is arranged on one side of the clamping rod 25 facing the plug pin 24, a spring 26 is connected to the clamping rod 25, the plug pin 24 can be inserted into the slot 111, the clamping rod 25 can be inserted into the clamping groove 241, and an electromagnet 27 is jointly installed at one end of the clamping rod 25 away from the slot 111 and the housing 1.

[0053] One end of the pulling seat 21 inserted into the installation opening 15 is adapted to the installation opening 15, and a sealing gasket 28 is arranged along the circumferential direction of the pulling seat 21 at one end of the pulling seat 21 inserted into the installation opening 15. Two abutting plates 29 are hinged to the side of the pulling seat 21 facing away from the installation opening 15, the two abutting plates 29 are respectively located on one side of the pulling seat 21, a strip-shaped hole 291 is formed in the abutting plate 29, a tightening bolt 292 is hinged to the housing 1, a strip-shaped block 293 is connected to the tightening bolt 292, and when the strip-shaped block 293 is in the same length direction as the strip-shaped hole 291, the strip-shaped block 293 can pass through the strip-shaped hole 291.

[0054] When replacing the first ionized oxygen air purifier 31, the drawer base 21 is pulled out of the housing 1. The drawer base 21 drives the connecting plate 232 to control the opening and closing assembly 5 to close the main air duct 13 where the first ionized oxygen air purifier 31 is located. At the same time, the opening and closing assembly 5 opens the bypass air duct 14 where the second ionized oxygen air purifier 34 is located. Then, the drawer plate 22 is separated from the drawer base 21, and the drawer plate 22 and the first ionized oxygen air purifier 31 are separated from the drawer base 21. When the drawer base 21 is pulled to the in-place position, the insertion pin 24 is inserted into the insertion slot 111. And during the process of the insertion pin 24 being inserted into the insertion slot 111, it acts on the guiding surface 251, causing the clamping rod 25 to first move away from the insertion pin 24 and then insert into the clamping slot 241, realizing the automatic locking of the drawer base 21, avoiding the sliding of the drawer base 21 during maintenance and affecting the installation of the first ionized oxygen air purifier 31, the first activated carbon adsorption module 32, and the first photocatalytic oxidation purifier 33, and avoiding causing the opening and closing assembly 5 to open the main air duct 13, thereby causing gas leakage.

[0055] After installing the new first ionized oxygen air purifier 31 on the drawer base 21, when the drawer base 21 is pushed into the housing 1, the electromagnet 27 is activated. The electromagnet 27 drives the clamping rod 25 away from the insertion slot 111, so that the insertion pin 24 can be disengaged from the insertion slot 111, enabling the drawer base 21 to be pushed back into the housing 1 again. When the drawer base 21 is inserted into the installation opening 15, the abutting plate 29 is flipped so that the strip-shaped hole 291 passes through the strip-shaped block 293, and then when the strip-shaped block 293 is rotated, the strip-shaped block 293 presses the abutting plate 29, thereby realizing the fixation of the drawer base 21 in the housing 1, which is convenient for installation and fixation. At the same time, the sealing gasket 28 plays a sealing role, reducing the leakage of gas in the housing 1 from the installation opening 15. Similarly, the replacement of the first activated carbon adsorption module 32 and the first photocatalytic purifier only requires pulling the corresponding drawer base 21 and drawer plate 22 in sequence.

[0056] The settings of the first replacement opening 16, the second replacement opening 17, and the third replacement opening 18 facilitate the replacement of the second ionized oxygen air purifier 34, the second activated carbon adsorption module 35, and the second photocatalytic oxidation purifier 36.

[0057] As Figure 6 , the installation part 4 includes a connecting block 41. The connecting block 41 is installed on the corresponding drawer plate 22. The connecting block 41 has a support plate 42. When the drawer plate 22 connected to the connecting block 41 is located in the corresponding insertion opening 211, the support plate 42 is supported on the corresponding sliding plate 231. Two limiting rods 43 are installed at one end of the support plate 42 away from the connecting block 41. The two limiting rods 43 are L-shaped and are arranged oppositely. The two limiting rods 43 are respectively located at two corners of the drawer plate 22. When the first activated carbon adsorption module 32 is located on the support plate 42, two corners of the first activated carbon adsorption module 32 are respectively located in the recesses of the two limiting rods 43.

[0058] The draw-out plate 22 drives the connection block 41 to move, thereby enabling the support plate 42 and the limiting rod 43 to drive the first activated carbon adsorption module 32 to separate from the draw-out seat 21, and the limiting rod 43 and the connection block 41 start to limit the front end and the rear end of the first activated carbon adsorption module 32.

[0059] Such as Figure 7 , the opening and closing assembly 5 includes two fixed sleeves 51. The fixed sleeves 51 are arranged in the side air duct 14. The peripheral surface of the fixed sleeve 51 is provided with air vents 511. A secondary telescopic member 52 is installed in the fixed sleeve 51. The secondary telescopic member 52 can pass through the side air duct 14 and block the main air duct 13. The secondary telescopic member 52 is connected to the draw-out assembly 2; The secondary telescopic member 52 includes a sliding sleeve plate 521. The fixed sleeve 51 is provided with a first sliding groove 512 along its length direction. The sliding sleeve plate 521 is connected with a first limiting block 5211. The first limiting block 5211 is slidably arranged in the first sliding groove 512. The sliding sleeve plate 521 is sleeved in the fixed sleeve 51 and fits with the inner wall of the fixed sleeve 51. A second sliding groove 5212 is formed in the sliding sleeve plate 521. A sliding plate 522 is inserted into the sliding sleeve plate 521. The sliding plate 522 is connected with a second limiting block 5221. The second limiting block 5221 is slidably arranged in the second sliding groove 5212.

[0060] When both the sliding plate 522 and the sliding sleeve plate 521 reach the stretching limit, the sliding plate 522 and the sliding sleeve plate 521 jointly block the main air duct 13.

[0061] Among the two fixed sleeves 51 of the opening and closing assembly 5 near the air inlet, one fixed sleeve 51 is arranged near the air inlet end of the second ionic oxygen air purifier 34, and the other fixed block is arranged near the exhaust end of the second ionic oxygen air purifier 34. When the two sliding plates 522 extend into the main air duct 13, one sliding plate 522 is arranged near the air inlet end of the first ionic oxygen air purifier 31, and the other sliding plate 522 is arranged near the exhaust end of the first ionic oxygen air purifier 31.

[0062] Among the two fixed sleeves 51 of the opening and closing assembly 5 located in the middle of the housing 1, one fixed sleeve 51 is arranged near the air inlet end of the second activated carbon adsorption module 35, and the other fixed block is arranged near the exhaust end of the second activated carbon adsorption module 35. When the two sliding plates 522 extend into the main air duct 13, one sliding plate 522 is arranged near the air inlet end of the first activated carbon adsorption module 32, and the other sliding plate 522 is arranged near the exhaust end of the first activated carbon adsorption module 32.

[0063] Among the two fixing sleeves 51 of the opening and closing assembly 5 near the exhaust port, one fixing sleeve 51 is arranged near the air inlet end of the second photocatalytic oxidation purifier 36, and the other fixing block is arranged near the exhaust port of the second photocatalytic oxidation purifier 36. When the two sliding plates 522 extend into the main air duct 13, one sliding plate 522 is arranged near the air inlet end of the first photocatalytic oxidation purifier 33, and the other sliding plate 522 is arranged near the exhaust port of the first photocatalytic oxidation purifier 33.

[0064] During normal operation, the secondary telescopic member 52 is located within the fixing sleeve 51, and the secondary telescopic member 52 closes the ventilation port 511, keeping the corresponding part of the bypass air duct 14 in a closed state. When maintenance and replacement are required, the connecting plate 232 drives the sliding plate 522 and the sliding sleeve plate 521 to move. When both the sliding plate 522 and the sliding sleeve plate 521 reach the extension limit, the sliding plate 522 and the sliding sleeve plate 521 jointly block the main air duct 13, while the ventilation port 511 opens, opening the corresponding part of the bypass air duct 14.

[0065] The implementation principle of the embodiment of this application is as follows: During normal operation, the gas sequentially passes through the first ionic oxygen air purifier 31, the first activated carbon adsorption module 32, and the first photocatalytic oxidation purifier 33. The first ionic oxygen air purifier 31 plays a role in quickly removing odors and killing microorganisms, and the first activated carbon adsorption module 32 further adsorbs and purifies the residual molecules and non-polar organic substances. Since the first activated carbon adsorption module 32 is prone to saturation, the first photocatalytic oxidation purifier 33 continuously decomposes the unadsorbed molecules to ensure the purification effect of the gas.

[0066] When the first ionic oxygen air purifier 31 needs to be replaced, the corresponding draw component 2 is extracted. The draw component 2 simultaneously drives the corresponding opening and closing assembly 5 to start. The opening and closing assembly 5 partially closes the main air duct 13 corresponding to the first ionic oxygen air purifier 31. At the same time, the opening and closing assembly 5 opens the part of the bypass air duct 14 corresponding to the second ionic oxygen air purifier 34. The gas can first enter the bypass air duct 14, pass through the second ionic oxygen air purifier 34, and then be discharged into the main air duct 13 from the first ventilation port 19, and then pass through the first activated carbon adsorption module 32 and the first photocatalytic oxidation purifier 33. At this time, the first ionic oxygen air purifier 31 can be removed from the corresponding draw component 2 and replaced. After the replacement is completed, the draw component 2 is reinserted into the housing 1, and the corresponding opening and closing assembly 5 closes the corresponding part of the bypass air duct 14 (i.e., the air inlet end and the exhaust port of the second ionic oxygen air purifier 34) again, and opens the corresponding part of the main air duct 13 (i.e., the air inlet end and the exhaust port of the first ionic oxygen air purifier 31).

[0067] And so on. When replacing the first activated carbon adsorption module 32, the gas sequentially passes through the first ionic oxygen air purifier 31, the second activated carbon adsorption module 35 and the first photocatalytic oxidation purifier 33. When replacing the first photocatalytic oxidation purifier 33, the gas sequentially passes through the first ionic oxygen air purifier 31, the first activated carbon adsorption module 32 and the second photocatalytic oxidation purifier 36. The gas treatment device at the tail end of the laboratory exhaust gas can be maintained without shutting down the machine, and still has the gas treatment effect during maintenance, ensuring the continuous progress of the experiment.

[0068] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
