Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to a multi-stage chamber-type air inactivation device. Background Technology

[0002] With the increasing demands for air purification quality in fields such as healthcare, food processing, and public places, air inactivation equipment, as a core device for removing harmful bacteria, viruses, volatile organic compounds, and dust impurities from the air, is finding increasingly widespread applications. Currently, air inactivation equipment on the market mainly employs single or combined technologies such as high-temperature thermal inactivation, irradiation sterilization, activated carbon adsorption filtration, and ozone disinfection. While these technologies can achieve basic air purification functions, many technical challenges remain to be addressed in practical applications, severely impacting the equipment's operating efficiency, sterilization effectiveness, and operating costs.

[0003] Currently, existing air inactivation devices still have shortcomings in use: 1. High-temperature thermal inactivation is one of the most thorough sterilization methods in air inactivation technology. Its principle is to destroy the protein structure of harmful microorganisms by heating the air to a specific high temperature (usually not lower than 120°C), thus achieving complete inactivation. However, existing equipment using high-temperature inactivation technology generally suffers from serious heat energy waste: on the one hand, the hot air after high-temperature treatment is directly discharged into the environment without recovering and utilizing the large amount of heat energy it carries, resulting in serious energy loss; on the other hand, the fresh cold air to be treated needs to be directly heated from room temperature to the temperature required for high-temperature inactivation. This not only involves a long heating process and slow heating rate, but also causes the heating elements (such as resistance wires, heating tubes, etc.) to operate under high load for a long time. This not only increases the energy consumption cost of the equipment, but also easily leads to accelerated aging of the heating elements and shortens the service life of the equipment. Especially in large-scale air treatment scenarios, this "direct discharge" heat energy waste mode will cause huge energy consumption, which is not in line with the development trend of energy conservation and environmental protection. 2. Existing air inactivation equipment often uses a fixed structure design for its internal airflow channels, such as fixed partitions or a single flow chamber. This makes it impossible to dynamically adjust the airflow path and flow area according to the actual airflow velocity entering the equipment. In practical applications, the airflow velocity is affected by various factors such as external fan power, pipe resistance, and ventilation requirements of the usage scenario, resulting in a large fluctuation range. When the negative pressure system has a large air extraction volume or high ventilation requirements, the airflow velocity will increase significantly. At this time, the fixed airflow channel will cause the air to pass through the sterilization area quickly, forming a "short-circuit flow." Harmful microorganisms will not stay in the high temperature or irradiation environment for a sufficient time, resulting in incomplete sterilization. Conversely, when the airflow velocity is too slow, the air stays in the sterilization area for too long, which will not only cause low equipment processing efficiency but may also cause the internal components of the equipment to age due to excessively high local temperatures, and may even cause organic matter decomposition, resulting in secondary pollution and affecting the air purification quality. This "one-size-fits-all" fixed structure design makes it difficult for the equipment to adapt to the airflow requirements under different working conditions, resulting in poor sterilization effect stability. 3. Activated carbon, due to its rich pore structure and excellent adsorption performance, is widely used in air inactivation equipment to adsorb impurities such as dust, odors, and volatile organic compounds in the air. However, the adsorption capacity of activated carbon has a physical saturation limit, and the activated carbon filter layers in existing equipment are mostly statically fixed: one side of the filter layer (adsorption surface) is in constant contact with the airflow and continuously adsorbs impurities, while the other side (backlight surface) cannot fully contact the airflow and is difficult to be irradiated by the radiation sterilization device, causing its deep pores to be easily blocked by organic matter, making regeneration impossible. As the usage time increases, the adsorption efficiency of the activated carbon filter layer will drop rapidly from the initial high value. When adsorption saturation is reached, it must be replaced in time to ensure the filtration effect. Frequent replacement of activated carbon filter layers not only increases the user's consumable costs, but also requires downtime for maintenance, affecting the continuous operating efficiency of the equipment and causing many inconveniences to the user. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing air inactivation devices, such as heat energy waste, poor airflow control, and easy saturation of activated carbon, and to propose a multi-stage chamber air inactivation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-stage chamber-type air inactivation device includes a housing, which contains a heat exchange section, a radiation sterilization section, and a high-temperature inactivation section. The high-temperature inactivation section contains an inactivation unit, which consists of two high-temperature inactivation chambers placed side by side and two sets of airflow path control structures. The two high-temperature inactivation chambers are fixedly connected by a second air injection pipe. The two high-temperature inactivation chambers can increase the inactivation time of the air in the inactivation unit. The radiation sterilization section is equipped with an irradiation sterilization unit, which includes a photohydrogen ion generator, an irradiation sterilization chamber, and multiple activated carbon filter layers. A first gas injection pipe is fixedly connected to one side of the irradiation sterilization chamber. One end of the first gas injection pipe is fixedly extended into the adjacent high-temperature inactivation chamber and is tangential to the inner wall of the high-temperature inactivation chamber, so that air enters tangentially to form a swirling flow to increase the residence time. The heat exchange section is equipped with a heat recovery unit, which includes an outer heat exchange tube and an inner heat exchange tube fixed inside the outer heat exchange tube. A hot air pipe is fixedly connected to one side of the inner heat exchange tube, and one end of the hot air pipe is fixedly connected to a corresponding high-temperature inactivation chamber. This is used to inject inactivated high-temperature air into the inner heat exchange tube to exchange heat with the cold air in the outer heat exchange tube, thereby realizing heat recovery.

[0006] In one possible design, the wind path control structure includes a rotating shaft rotatably connected within a high-temperature inactivation chamber. Multiple longitudinally arranged partition plates are rotatably fitted onto the outer wall of the rotating shaft. These partition plates are fixed within the high-temperature inactivation chamber. Each partition plate contains two symmetrical ventilation holes for allowing air to flow through the ventilation holes within the high-temperature inactivation chamber. A sealing plate is slidably connected to the top of each partition plate to close adjacent ventilation holes. Two adjacent sealing plates are symmetrically placed, allowing air to flow along a serpentine path as the sealing plates close the ventilation holes, thereby increasing the inactivation time.

[0007] In one possible design, two sets of symmetrically arranged closed structures are provided between two adjacent partition plates. The closed structure includes an outer liner plate fixed to the outer wall of the rotating shaft. The top of the outer liner plate is fixedly connected to the bottom of the partition plate. The length of the outer liner plate away from the rotating shaft is adapted to the inner cavity of the high-temperature inactivation chamber. An inner liner plate is longitudinally slidably connected inside the outer liner plate. The length of the inner liner plate is adapted to the inner cavity of the high-temperature inactivation chamber. An air flow gap is formed between the bottom of the inner liner plate and the top of the partition plate below it. When the rotating shaft rotates, the inner liner plate moves down along the arc-shaped rod of the inner wall of the high-temperature inactivation chamber to reduce the air flow gap and reduce the air velocity.

[0008] In one possible design, a drive unit is also included, comprising two curved blades fixed to the outer walls of two rotating shafts. The second gas injection pipe is located near the bottom of the high-temperature inactivation chamber and its two ends are tangent to the inner wall of the high-temperature inactivation chamber. The first gas injection pipe is located near the top of the high-temperature inactivation chamber. The outlet end of the first gas injection pipe extends into the first high-temperature inactivation chamber and faces the corresponding curved blade in that chamber. The two ends of the second gas injection pipe extend into the two high-temperature inactivation chambers respectively, and their outlet directions are both facing the curved blades in the corresponding chambers, for driving the rotating shafts to rotate when the air flow rate is high. A transmission shaft is fixed to the top of the rotating shafts, and the top end of the transmission shaft extends rotatably into the protective cover above the high-temperature inactivation chambers. A torsion spring is sleeved on the outer wall of the transmission shaft for driving the rotating shafts to return to their original rotation.

[0009] In one possible design, the irradiation sterilization unit further includes multiple rotating blades rotatably connected to the irradiation sterilization chamber via a rotating shaft. Multiple activated carbon filter layers are respectively fixed within the rotating blades for air adsorption and filtration. The flash tube of the photo-ion generator extends into the irradiation sterilization chamber and is located above the rotating blades, for irradiating and sterilizing the air and activated carbon filter layers. A spur gear is fixed to one end of the rotating shaft of the rotating blades. A sliding plate is slidably connected to one side of the irradiation sterilization chamber. A rack meshing with the spur gear is fixed to the bottom of the sliding plate. The sliding plate is connected to the output shaft of a pneumatic cylinder fixed to the irradiation sterilization chamber, for driving the rotating blades to flip so that the activated carbon filter layers are irradiated by the photo-ion generator.

[0010] In one possible design, the heat recovery unit further includes a first spiral guide vane fixed to the outer wall of the inner heat exchange tube, the outer wall of the first spiral guide vane abutting against the inner wall of the outer heat exchange tube, for increasing the heat exchange time of cold air in the outer heat exchange tube; The top of the external heat exchange tube is connected to the bottom of the irradiation sterilization chamber via a second connecting pipe; a second spiral guide vane is fixed inside the internal heat exchange tube to increase the heat exchange time of the high-temperature air inside the internal heat exchange tube; an exhaust pipe is fixedly connected to the end of the internal heat exchange tube away from the hot air pipe to discharge the air after heat exchange; multiple heat dissipation fins extending into the external heat exchange tube are fixedly penetrated through the outer wall of the internal heat exchange tube to increase the heat conduction efficiency.

[0011] In one possible design, a mixing chamber is fixed on one side of the housing, and the mixing chamber is connected to an external heat exchange tube through multiple first connecting pipes for injecting cold air into the external heat exchange tube; an ozone generator is fixed at the bottom of the radiation sterilization section, and the ozone outlet pipe of the ozone generator extends into the mixing chamber for mixing the cold air with ozone for preliminary sterilization.

[0012] In one possible design, the inner wall of the heat exchange section is fixed with multiple C-shaped clamps for clamping the external heat exchange tube; the high-temperature inactivation section is fixed with an installation base, and both high-temperature inactivation chambers are fixedly penetrated through the installation base.

[0013] In one possible design, a control unit is also provided inside the housing. A main control center is fixed inside the control unit. Multiple carbon fiber far-infrared heating tubes are fixedly embedded in the inner walls of the two high-temperature inactivation chambers. The main control center is electrically connected to the ozone generator, the photo-hydrogen ion generator, and the carbon fiber far-infrared heating tubes to control the inactivation and sterilization process.

[0014] In one possible design, an annular component is fixed to the inner wall of the mixing chamber, and multiple perforations are provided in the annular component. The ozone outlet pipe of the ozone generator extends into the annular component to allow ozone to be evenly discharged through the perforations. A drive rod is rotatably connected to the inner wall of the mixing chamber, and a turbine is fixed to one end of the drive rod to drive the turbine to rotate when cold air flows, thereby enhancing the mixing effect of ozone and air.

[0015] Beneficial Effects: This invention employs a three-stage synergistic sterilization method: ozone preliminary sterilization, photo-hydrogen ionization sterilization, and high-temperature thermal inactivation. This progressively removes harmful bacteria, viruses, and organic matter from the air. The high-temperature inactivation section features two series-connected high-temperature inactivation chambers. Combined with a wind path control structure, the airflow path and flow gap can be dynamically adjusted according to the intake airflow velocity. When the intake airflow velocity is high, the airflow drives the curved blades to rotate the shaft, and the sealing plate closes some of the ventilation holes, causing the air to flow along a serpentine path. The inner liner plate moves downward to reduce the flow gap, extending the residence time of the air in the high-temperature inactivation chamber. When the flow velocity decreases, the torsion spring drives the rotating shaft to reset, ensuring that the equipment achieves ideal inactivation effects under different airflow rates, effectively solving the problem of incomplete sterilization at high flow rates. In this invention, the heat exchange section adopts an inner and outer double heat exchange tube structure. The high-temperature inactivation air in the inner heat exchange tube and the cold air to be treated in the outer heat exchange tube exchange heat efficiently. The first spiral guide vane in the outer heat exchange tube and the second spiral guide vane in the inner heat exchange tube extend the flow path of the hot and cold air, respectively. The heat dissipation fins increase the heat conduction area and significantly improve the heat exchange efficiency. The cold air to be treated enters the subsequent sterilization stage after preheating, reducing the heating energy consumption of the high-temperature inactivation section. The high-temperature inactivation air is discharged after cooling, avoiding direct waste of heat energy and significantly reducing the overall operating energy consumption of the equipment. In this invention, the activated carbon filter layer of the radiation sterilization section is fixed on the rotating blades. The flash tube of the photohydrogen ion generator can not only irradiate and sterilize the filtered air, but also irradiate the surface of the activated carbon filter layer to decompose the adsorbed organic matter. The pneumatic cylinder drives the rotating blades to rotate through the meshing of the rack and spur gear, so that the two sides of the activated carbon filter layer are alternately irradiated for desorption and regeneration, avoiding the filter layer from being frequently replaced due to adsorption saturation, extending its service life, and reducing equipment maintenance and operating costs. In this invention, a ring-shaped component and a turbine are installed inside the mixing chamber. Ozone generated by the ozone generator is evenly discharged towards the center through multiple perforations in the ring-shaped component. Simultaneously, cold air introduced by an external fan drives the turbine to rotate, throwing the cold air outwards. This ensures that the ozone and cold air fully contact and mix evenly within the mixing chamber. This structure avoids excessively high or low local ozone concentrations, ensuring both initial sterilization effectiveness and reducing ozone residue, thus minimizing harm to humans and the environment. In this invention, the multi-stage chamber design effectively extends the air inactivation time and improves the sterilization effect. The heat recovery section realizes heat exchange between hot and cold air, reducing heat waste and energy consumption. The wind path control structure automatically adjusts the path according to the air flow rate to avoid "short circuit" or overheating, ensuring thorough sterilization. The irradiation sterilization section realizes the desorption and regeneration of activated carbon through a photo-hydrogen ion generator and a reversible activated carbon filter layer, extending the service life and reducing maintenance costs. The overall structure of the equipment is reasonable, the operation is stable, and it is suitable for various air inactivation scenarios, with significant economic and social benefits.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] In one embodiment: Refer to Figure 1 and Figure 2 A multi-stage cavity air inactivation device, relating to the field of air purification technology, mainly includes a housing 1, a mixing chamber 7, a heat exchange section 2, a radiation sterilization section 3, a high-temperature inactivation section 4, and a control unit 5. The housing 1 is a rectangular cavity structure, and the mixing chamber 7 is fixedly penetrated through one side wall of the housing 1 and is located in the lower region of the housing 1.

[0020] Furthermore, refer to Figure 2 and Figure 4 The mixing chamber 7 is a cylindrical cavity structure. One end of the mixing chamber 7 is connected to the air outlet of the external fan to introduce the cold air to be treated. Three first connecting pipes 9 are evenly distributed at the other end of the mixing chamber 7. The three first connecting pipes 9 are evenly arranged along the circumference of the mixing chamber 7. The first connecting pipe 9 is a cylindrical structure. One end of the first connecting pipe 9 is fixedly connected to the outer wall of the mixing chamber 7 and connected to the inside of the mixing chamber 7. The other end extends into the external heat exchange pipe 11 to realize the airflow communication between the mixing chamber 7 and the heat exchange section 2.

[0021] Furthermore, refer to Figures 2-4 An ozone generator 8 is fixed to the bottom inner wall of the radiation sterilization section 3. The ozone generator 8 is fixed to the bottom of the irradiation sterilization chamber 19 by a bracket. The power cord of the ozone generator 8 is electrically connected to the main control center 6 of the control unit 5, and the main control center 6 controls its start-up and shutdown and the ozone output concentration.

[0022] Furthermore, refer to Figure 2 and Figure 4 Multiple C-shaped clamps 10 are fixed to the inner wall of one side of the heat exchange section 2. There are 4 to 6 C-shaped clamps 10, evenly arranged along the length of the external heat exchange tube 11. The C-shaped clamps 10 are made of elastic metal, and their inner diameter matches the outer diameter of the external heat exchange tube 11. The elastic clamping force of the C-shaped clamps 10 securely clamps the external heat exchange tube 11 to the inner wall of the heat exchange section 2, ensuring that the external heat exchange tube 11 does not shift during equipment operation. The external heat exchange tube 11 has a circular tubular structure, and both ends of the external heat exchange tube 11 are closed. The structure includes an external heat exchange tube 11, one end of which is fixedly connected to and communicates with the ends of three first connecting tubes 9, allowing air in the mixing chamber 7 to enter the interior of the external heat exchange tube 11 through the first connecting tubes 9. A second connecting tube 13 is fixedly connected to the top of the external heat exchange tube 11. The second connecting tube 13 is a circular tube structure. The lower end of the second connecting tube 13 is fixedly connected to and communicates with the top outer wall of the external heat exchange tube 11, and the upper end extends to the bottom of the irradiation sterilization chamber 19 of the radiation sterilization section 3, thereby achieving airflow communication between the external heat exchange tube 11 and the irradiation sterilization chamber 19.

[0023] Furthermore, refer to Figure 2 , Figure 5 and Figure 6 An inner heat exchange tube 14 is fixedly installed inside the outer heat exchange tube 11. The inner heat exchange tube 14 has a circular tube structure, and its axis coincides with the axis of the outer heat exchange tube 11, forming an annular cold air channel between them. A first spiral guide vane 12 is fixedly sleeved on the outer wall of the inner heat exchange tube 14. The material of the first spiral guide vane 12 is the same as that of the inner heat exchange tube 14. The outer wall of the first spiral guide vane 12 is in close contact with the inner wall of the outer heat exchange tube 11, dividing the annular cold air channel into a spiral channel, extending the flow path and heat exchange time of the cold air within the channel. One end of the 4 is fixedly connected to a hot air pipe 15. The hot air pipe 15 is a circular pipe structure. One end of the hot air pipe 15 is fixedly connected to the outer wall of the inner heat exchange tube 14 and is in communication with it. The other end extends to the side of the corresponding high temperature inactivation chamber 28 in the high temperature inactivation section 4 near the top, so as to realize the airflow communication between the inner heat exchange tube 14 and the high temperature inactivation chamber 28. A second spiral guide vane 17 is fixed inside the inner heat exchange tube 14. The outer wall of the second spiral guide vane 17 is in close contact with the inner wall of the inner heat exchange tube 14 to form a spiral high temperature air channel, which prolongs the flow path and heat exchange time of the high temperature air in the inner heat exchange tube 14.

[0024] Furthermore, refer to Figures 3-4 Multiple heat dissipation fins 16 are fixedly penetrated through the outer wall of the inner heat exchange tube 14. The number of heat dissipation fins 16 is 20 to 30, which are evenly arranged along the length of the inner heat exchange tube 14. The heat dissipation fins 16 are rectangular sheet structures and are set perpendicular to the axis of the inner heat exchange tube 14. The end of the heat dissipation fins 16 away from the inner heat exchange tube 14 extends into the annular cold air channel inside the outer heat exchange tube 11, increasing the heat conduction area between the inner heat exchange tube 14 and the cold air and improving the heat exchange efficiency. The end of the inner heat exchange tube 14 away from the hot air pipe 15 is fixedly connected to an exhaust pipe 18. The exhaust pipe 18 is a circular pipe structure. One end of the exhaust pipe 18 is fixedly connected to the end of the inner heat exchange tube 14 and is connected to it. The lower end extends vertically downward to the bottom of the casing 1 for discharging the inactivated air after heat exchange from the equipment.

[0025] Furthermore, refer to Figure 2 , Figure 3 and Figure 9An irradiation sterilization chamber 19 is fixed to one inner wall of the radiation sterilization section 3. The irradiation sterilization chamber 19 has a rectangular cavity structure. The bottom of the irradiation sterilization chamber 19 is fixedly connected to the upper end of the second connecting pipe 13, so that the air in the heat exchange tube 11 outside the heat exchange section 2 can enter the interior of the irradiation sterilization chamber 19 through the second connecting pipe 13. A first air injection pipe 27 is fixedly connected to the upper part of one side of the irradiation sterilization chamber 19. The first air injection pipe 27 has a circular tube structure. One end of the first air injection pipe 27 is fixedly connected to the outer wall of the irradiation sterilization chamber 19, and the other end extends to the top of the adjacent high-temperature inactivation chamber 28 in the high-temperature inactivation section 4. The end of the first air injection pipe 27 is tangent to the inner wall of the high-temperature inactivation chamber 28, so that the air can enter the chamber along the tangential direction of the inner wall of the high-temperature inactivation chamber 28.

[0026] Furthermore, refer to Figure 3 and Figure 8A photo-ion generator 20 is fixedly installed on the top of the irradiation sterilization chamber 19. The power range of the photo-ion generator 20 is 300 to 500 watts. Its flash tube extends vertically downwards into the interior of the irradiation sterilization chamber 19. The lower end of the flash tube is located in the middle area inside the irradiation sterilization chamber 19 and above the rotating blades 21. The photo-ion generator 20 generates photo-ion ions that irradiate the interior of the irradiation sterilization chamber 19 through the flash tube. This not only sterilizes the air filtered by the activated carbon filter layer 22, but also irradiates the surface of the activated carbon filter layer 22, decomposing the adsorbed organic matter. The interior of the irradiation sterilization chamber 19 is connected to multiple rotating blades 21 via a rotating shaft. There are four to six rotating blades 21, evenly arranged along the length of the irradiation sterilization chamber 19. Both ends of the rotating shaft are rotatably connected to the inner walls of both sides of the irradiation sterilization chamber 19 via bearings. Each rotating blade 21 has a rectangular frame structure, and an activated carbon filter layer 22 is fixed inside the frame of the rotating blade 21. The size of the activated carbon filter layer 22 is adapted to the size of the frame of the rotating blade 21, and it is used to adsorb and filter the air flowing from bottom to top. One end of the rotating shaft of each of the multiple rotating blades 21 extends rotatably into the irradiation sterilization chamber 19. On one side of the outer wall of the irradiation sterilization chamber 19, a slide rail is fixed, and a sliding plate 25 is slidably connected to the slide rail. A rack 24 is fixed to the bottom of the sliding plate 25. The length of the rack 24 is adapted to the length of the sliding plate 25. The rack 24 meshes with multiple spur gears 23. When the sliding plate 25 moves back and forth along the slide rail, the rack 24 drives the multiple spur gears 23 to rotate synchronously, thereby driving the rotating blades 21 to rotate around the axis. The rotation angle range is 180 degrees, so that both sides of the activated carbon filter layer 22 can alternately face the flash tube to receive irradiation. For desorption and regeneration, a pneumatic cylinder 26 is fixed to one side of the outer wall of the irradiation sterilization chamber 19. The pneumatic cylinder 26 is of the SC80 to 120 series. The cylinder body of the pneumatic cylinder 26 is fixed to the outer wall of the irradiation sterilization chamber 19 by a bracket. The output shaft of the pneumatic cylinder 26 is set in the horizontal direction, and the end of the output shaft is fixedly connected to one end of the sliding plate 25. The pneumatic cylinder 26 drives the output shaft to extend and retract, which drives the sliding plate 25 to move back and forth along the slide rail, thereby realizing the flipping action of the rotating blade 21. The working frequency of the pneumatic cylinder 26 can be adjusted according to the adsorption of the activated carbon filter layer 22, and is usually set to flip once every 3 to 6 hours.

[0027] Furthermore, refer to Figure 2 and Figure 3The high-temperature inactivation section 4 has a fixed mounting base 46 inside. Two high-temperature inactivation chambers 28 are fixedly inserted through the mounting base 46. Each high-temperature inactivation chamber 28 is a cylindrical cavity structure. The two high-temperature inactivation chambers 28 are placed side-by-side along the length of the mounting base 46. The two high-temperature inactivation chambers 28 are fixedly connected by a second gas injection pipe 29. The second gas injection pipe 29 is a cylindrical structure located near the bottom of each high-temperature inactivation chamber 28. Both ends of the second gas injection pipe 29 are fixedly connected to and communicate with the outer walls of the two high-temperature inactivation chambers 28, and the end of the second gas injection pipe 29 is connected to the outer wall of each high-temperature inactivation chamber 28. The inner walls of chambers 8 are tangential, allowing air to enter one high-temperature inactivation chamber 28 tangentially from another. Each high-temperature inactivation chamber 28 contains multiple carbon fiber far-infrared heating tubes, with 6 to 10 tubes evenly arranged around the circumference of the chamber. The carbon fiber far-infrared heating tubes are fixed to the inner wall of the chamber 28 by supports, which are set along the height of the chamber. The axis of the carbon fiber far-infrared heating tubes is parallel to the axis of the chamber, enabling uniform heating of the air inside the chamber and achieving high-temperature thermal inactivation of the air.

[0028] Furthermore, refer to Figure 9 and Figure 10 Each high-temperature inactivation chamber 28 is equipped with a set of airflow path control structures, which include a rotating shaft 30, a partition plate 35, a sealing plate 37, a stop block 38, and a sealing structure. The rotating shaft 30 has a cylindrical structure, and its axis coincides with the axis of the high-temperature inactivation chamber 28. The two ends of the rotating shaft 30 are rotatably connected to the top and bottom inner walls of the high-temperature inactivation chamber 28 through bearings. The outer wall of the rotating shaft 30 is rotatably fitted with a plurality of longitudinally arranged partition plates 35, the number of which is 8 to 12, evenly arranged along the length of the rotating shaft 30. The distance between two adjacent partition plates 35 is 80 to 120 mm. The partition plates 35 have a circular plate structure, the diameter of which matches the inner diameter of the high-temperature inactivation chamber 28. The edge of the partition plate 35 is fixedly connected to the inner wall of the high-temperature inactivation chamber 28. The center of the partition plate 35 is provided with a through hole that matches the rotating shaft 30. The rotating shaft 30 is rotatably connected to the through hole of the partition plate 35 through bearings, so that the rotating shaft 30 can rotate freely relative to the partition plate 35.

[0029] Furthermore, refer to Figure 10 and Figure 11Each partition plate 35 has two symmetrically placed ventilation holes 36. The ventilation holes 36 have a fan-shaped structure and are symmetrical about the center of the partition plate 35. The ventilation holes 36 penetrate the upper and lower surfaces of the partition plate 35 to allow air to flow between adjacent partition plates 35. A sealing plate 37 is slidably connected to the top of each partition plate 35. The sealing plate 37 has a fan-shaped plate structure, and its size is adapted to the size of the ventilation holes 36. The bottom of the sealing plate 37 has a groove, and the top of the partition plate 35 has a slide rail adapted to the groove. The sealing plate 37 slides along the top of the partition plate 35 through the cooperation of the groove and the slide rail, which can control the airflow between adjacent partition plates 35. The adjacent ventilation holes 36 are sealed, and the two adjacent sealing plates 37 are placed symmetrically. That is, when the sealing plate 37 of the upper partition plate 35 seals the left ventilation hole 36, the sealing plate 37 of the lower partition plate 35 seals the right ventilation hole 36. In this way, when the sealing plate 37 seals the adjacent ventilation holes 36, the air can only flow between the adjacent partition plates 35 through the unsealed ventilation holes 36, forming a serpentine winding path, which prolongs the residence time of the air in the high-temperature inactivation chamber 28. Multiple sealing plates 37 are fixedly sleeved on the outer wall of the rotating shaft 30. When the rotating shaft 30 rotates, it can drive all the sealing plates 37 to rotate synchronously, realizing the sealing and opening of the ventilation holes 36.

[0030] Furthermore, refer to Figure 10 A stop block 38 is fixed to the top of the uppermost partition plate 35. The stop block 38 is fixed at the top of the partition plate 35 near the ventilation hole 36. When the sealing plate 37 rotates to the limit position of closing the ventilation hole 36, the edge of the sealing plate 37 contacts the stop block 38, thereby limiting the sealing plate 37 and preventing the sealing plate 37 from rotating excessively.

[0031] Furthermore, refer to Figure 10 and Figure 12 Two sets of symmetrically arranged closed structures are provided between two adjacent partition plates 35. The closed structure includes an outer liner plate 39, an inner liner plate 40, and an arc-shaped rod 41. The outer liner plate 39 is a rectangular plate structure and is fixed to the outer wall of the rotating shaft 30. The top of the outer liner plate 39 is fixedly connected to the bottom of the adjacent upper partition plate 35. The length of the outer liner plate 39 away from the rotating shaft 30 is adapted to the inner cavity of the high-temperature inactivation chamber 28. The sliding fit clearance range is 0.5 to 1 mm. The inner liner plate 40 is longitudinally slidably connected inside the outer liner plate 39. The inner liner plate 40 is a rectangular plate structure and its length is adapted to the length of the outer liner plate 39. The length of the inner liner plate 40 is adapted to the inner cavity of the high-temperature inactivation chamber 28. The sliding fit clearance range is 0.5 to 1 mm. An air flow gap is formed between the bottom of the inner liner plate 40 and the top of the lower partition plate 35. When the inner liner plate 40 moves down, the height of the air flow gap decreases, thereby reducing the air velocity.

[0032] Furthermore, refer to Figure 10and Figure 12 An arc-shaped rod 41 is fixed to the inner wall of the high-temperature inactivation chamber 28. The arc-shaped rod 41 has a circular arc structure. The length of the arc-shaped rod 41 is adapted to the rotation trajectory of the inner liner plate 40. The top of the arc-shaped rod 41 is an inclined surface with an inclination angle ranging from 30 to 45 degrees. The bottom of the inner liner plate 40 slides in conjunction with the top of the arc-shaped rod 41. When the rotating shaft 30 drives the outer liner plate 39 to rotate, the bottom of the inner liner plate 40 slides along the inclined surface of the arc-shaped rod 41. Under the action of gravity, the inner liner plate 40 gradually moves down, reducing the air flow gap and completing the adjustment of the flow area.

[0033] Furthermore, refer to Figure 9 and Figure 10 The high-temperature inactivation section 4 also includes a drive unit, which is used to adjust the structure operation according to the wind force path driven by the wind entering the high-temperature inactivation chamber 28. The drive unit includes curved blades 31, a drive shaft 32, a protective cover 34, and a torsion spring 33. There are two curved blades 31, which are fixed on the outer walls of the two rotating shafts 30 respectively. The two curved blades 31 are located near the top and bottom of the high-temperature inactivation chamber 28 and correspond to the outlet ends of the first air injection pipe 27 and the second air injection pipe 29 respectively. The curved blades 31 have an arc-shaped blade structure. The outlet end of the first air injection pipe 27 extends into the first high-temperature inactivation chamber 28 and faces the corresponding curved blade 31 in the chamber. The two ends of the second air injection pipe 29 extend into the two high-temperature inactivation chambers 28 respectively, and their outlet directions are both facing the curved blades 31 in the corresponding chambers. When air is discharged from the air injection pipe, the airflow impacts the curved blades 31, driving the curved blades 31 to rotate the rotating shaft 30.

[0034] Furthermore, refer to Figure 9 and Figure 10 Both rotating shafts 30 have a drive shaft 32 fixed to their tops. The drive shaft 32 is cylindrical, and its bottom end is fixedly connected to the top end of the rotating shaft 30. The top end of the drive shaft 32 extends rotatably above the high-temperature inactivation chamber 28. Both high-temperature inactivation chambers 28 have a protective cover 34 fixed to their tops. The protective cover 34 is a cylindrical cavity structure, and its bottom end is fixedly connected to the top end of the high-temperature inactivation chamber 28. This protective cover protects the drive shaft 32 and the torsion spring 33. The top end of the drive shaft 32 is connected to the protective cover 34 via a bearing. The top inner wall is rotatably connected, and the outer wall of the drive shaft 32 is fitted with a torsion spring 33. The diameter of the steel wire of the torsion spring 33 ranges from 1.2 to 2.8 mm, the free length ranges from 25 to 38 mm, and the stiffness coefficient ranges from 0.8 to 1.6 N / mm. The top end of the torsion spring 33 is fixedly connected to the top inner wall of the protective cover 34 through a spring seat, and the spring seat is fixed to the inner wall of the protective cover 34 by bolts. The bottom end of the torsion spring 33 is fixedly connected to the outer wall of the drive shaft 32 through a spring seat, and the spring seat is fixedly fitted on the outer wall of the drive shaft 32.

[0035] Specifically, when the airflow drives the rotating shaft 30 to rotate, the torsion spring 33 is twisted and stores energy. When the airflow speed decreases, the torsion spring 33 releases its elastic potential energy and drives the rotating shaft 30 to reset and rotate.

[0036] Furthermore, refer to Figure 2 The control unit 5 has a rectangular hollow structure. The main control center 6, an industrial-grade PLC controller (model S7-200SMART series), is fixed to the bottom inner wall of the control unit 5 via a bracket, which is bolted to the inner wall of the control unit 5. A heat insulation layer is installed on the partition plate 1 between the control unit 5 and the high-temperature inactivation section 4. Ventilation holes and a cooling fan are provided on the housing of the control unit 5 to ensure that the main control center 6 operates at a suitable temperature.

[0037] Furthermore, refer to Figure 2 and Figure 7 The main control center 6 is electrically connected to the ozone generator 8, photo-ion generator 20, carbon fiber far-infrared heating tube, and pneumatic cylinder 26 via power and signal lines, enabling start / stop control, parameter adjustment, and status monitoring of each component. The main control center 6 is equipped with a temperature sensor interface. A PT100 temperature sensor is fixed inside the high-temperature inactivation chamber 28, with its detection end extending into the interior of the chamber. The signal output end of the temperature sensor is electrically connected to the interface of the main control center 6 for real-time monitoring of the temperature inside the high-temperature inactivation chamber 28. When the temperature is lower than the set value, the main control center 6 controls the carbon fiber far-infrared heating tube to increase its power; when the temperature is higher than the set value, the main control center 6 controls the carbon fiber far-infrared heating tube to decrease its power, thus stabilizing the temperature inside the high-temperature inactivation chamber 28 within the set range.

[0038] Furthermore, refer to Figure 2 , Figure 7 and Figure 8 The main control center 6 is also equipped with a flow rate sensor interface. A flow rate sensor, model FS4001, is fixed inside the mixing chamber 7. The sensor's detection end is located at the air inlet of the mixing chamber 7 to monitor the airflow rate entering the equipment in real time. The signal output end of the flow rate sensor is electrically connected to the interface of the main control center 6. Based on the detection data from the flow rate sensor, the main control center 6 adjusts the operating frequency of the pneumatic cylinder 26 and the irradiation intensity of the photoionizer 20. When the flow rate is high, the rotation frequency of the pneumatic cylinder 26 and the power of the photoionizer 20 are increased to ensure sterilization effect; when the flow rate is low, the operating parameters of relevant components are appropriately reduced to save energy.

[0039] In another embodiment: Refer to Figure 13 and Figure 14The structure of this embodiment is basically the same as that of the previous embodiment, except that: an annular part 42 is fixed in the middle of the inner wall of the mixing chamber 7. The annular part 42 is a circular structure with an outer diameter that matches the inner diameter of the mixing chamber 7. Multiple perforations 43 are evenly arranged in the circumferential direction of the annular part 42. The number of perforations 43 is 12 to 20. The perforations 43 are arranged radially along the annular part 42. The ozone generator 8 is fixed in the bottom inner wall of the radiation sterilization section 3. The ozone generator 8 is selected to be an ozone generator with an output concentration of 0.1 to 0.3 mg / m³. The ozone outlet pipe of the ozone generator 8 extends horizontally into the interior of the mixing chamber 7, and the end of the ozone outlet pipe is fixedly extended to the inner ring area of ​​the annular part 42, so that ozone can be evenly discharged into the middle area of ​​the mixing chamber 7 through the multiple perforations 43 of the annular part 42.

[0040] Reference Figure 13 and Figure 14 A drive rod 44 is rotatably connected to one side of the inner wall of the mixing chamber 7 away from the external fan. The drive rod 44 is a cylindrical structure. One end of the drive rod 44 is rotatably connected to the inner wall of the mixing chamber 7 through a bearing. The other end of the drive rod 44 is fixedly connected to a turbine 45, which is located in the central area inside the mixing chamber 7.

[0041] Specifically, when the external fan introduces cold air into the mixing chamber 7, the flow of cold air will generate thrust on the blades of the turbine 45, driving the turbine 45 to rotate the drive rod 44 around the bearing. During the rotation of the turbine 45, the cold air is thrown out in all directions, so that the cold air is fully mixed with the ozone discharged from the annular component 42, thereby improving the initial sterilization effect.

[0042] A method of using a multi-stage chamber-type air inactivation device includes the following steps: S1. Start-up phase: The equipment is started through the main control center 6, and the external fan starts working, introducing the cold air to be treated into the mixing chamber 7; at the same time, the main control center 6 controls the ozone generator 8 to start, and the generated ozone is evenly discharged into the middle area of ​​the mixing chamber 7 through the perforation 43 of the annular component 42; the flow of cold air drives the turbine 45 to rotate, throwing the cold air out in all directions, so that the ozone and cold air are fully mixed, and the large number of harmful bacteria in the air are initially killed.

[0043] S2, Heat exchange stage: The mixed air enters the outer heat exchange tube 11 of the heat exchange section 2 through the first connecting pipe 9, and flows along the spiral channel formed by the first spiral guide vane 12, extending the flow path; at the same time, the high-temperature inactivated air discharged from the high-temperature inactivation section 4 enters the inner heat exchange tube 14 through the hot air pipe 15, and flows along the spiral channel formed by the second spiral guide vane 17; cold air and high-temperature air exchange heat through the tube walls of the outer heat exchange tube 11 and the inner heat exchange tube 14 and the heat dissipation fins 16.

[0044] S3. Radiation Sterilization and Activated Carbon Regeneration Stage: Preheated air enters the irradiation sterilization chamber 19 through the second connecting pipe 13, passing through the activated carbon filter layer 22 inside the rotating blades 21 from bottom to top. Impurities and dust in the air are adsorbed and filtered. The main control center 6 controls the photo-hydrogen ion generator 20 to start, and the flash tube releases photo-hydrogen ions to irradiate and sterilize the filtered air. At the same time, it irradiates the upper surface of the activated carbon filter layer 22 to decompose the adsorbed organic matter. According to the equipment running time or the activated carbon adsorption status, the main control center 6 controls the pneumatic cylinder 26 to start. The output shaft of the pneumatic cylinder 26 extends and retracts, driving the sliding plate 25 to move back and forth along the slide rail. The rack 24 drives the spur gear 23 to rotate, thereby driving the rotating blades 21 to rotate 180 degrees, so that the lower surface of the activated carbon filter layer 22 turns upward and continues to receive irradiation desorption and regeneration. The regenerated activated carbon filter layer 22 can continue to perform adsorption and filtration.

[0045] S4. High-Temperature Inactivation Stage: After radiation sterilization, the air enters the first high-temperature inactivation chamber 28 through the first air injection pipe 27 along the tangential direction of the inner wall of the high-temperature inactivation chamber 28. When the airflow velocity is high, to avoid the air passing through the high-temperature inactivation chamber 28 too quickly and thus failing to fully inactivate, the high-velocity airflow impacts the curved blades 31, driving the curved blades 31 to rotate the rotating shaft 30. The rotating shaft 30 drives the sealing plate 37 to rotate, closing part of the ventilation holes 36. Since the upper and lower adjacent sealing plates 37 are symmetrically placed, air can only pass through... The unsealed ventilation hole 36 flows along a serpentine path; at the same time, the rotating shaft 30 drives the outer liner 39 to rotate, and the inner liner 40 moves down along the inclined surface of the arc rod 41 under the action of gravity, reducing the air flow gap and reducing the air velocity; during the flow, the air is heated by the carbon fiber far-infrared heating tube, and harmful bacteria and viruses are completely inactivated; subsequently, the air enters the second high-temperature inactivation chamber 28 tangentially through the second air injection pipe 29, repeating the above path regulation and high-temperature inactivation process, further extending the residence time to ensure thorough sterilization.

[0046] S5. Exhaust and Heat Recovery Stage: After high-temperature inactivation, the air enters the inner heat exchange tube 14 through the hot air pipe 15, where it exchanges heat with the cold air in the outer heat exchange tube 11. The cooled inactivated air is then discharged from the equipment through the exhaust pipe 18 and can be directly discharged into the room or other areas that require air purification. The main control center 6 monitors the temperature inside the high-temperature inactivation chamber 28 in real time through a temperature sensor and adjusts the power of the carbon fiber far-infrared heating tube according to the temperature data to ensure that the temperature inside the chamber is stable within the set range. The flow rate sensor monitors the intake airflow rate in real time and adjusts the rotation frequency of the pneumatic cylinder 26 and the power of the photohydrogen ion generator 20 according to the flow rate data to ensure that the equipment can operate stably under different working conditions.

[0047] S6. Shutdown Phase: When the equipment completes the air inactivation operation or needs to be shut down, the main control center 6 sequentially shuts down the external fan, ozone generator 8, photo-hydrogen ion generator 20, carbon fiber far-infrared heating tube and pneumatic cylinder 26; after the air in the equipment is completely discharged, the main control center 6 cuts off the power supply and the equipment stops running.

[0048] However, as is well known to those skilled in the art, the working principles and wiring methods of the photo-ion generator 20, the ozone generator 8, and the main control center 6 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
