Description

Technical Field

[0001] This invention belongs to the field of air purification technology, and in particular relates to a multi-stage combined water-air separation water curtain air purification device. Background Technology

[0002] Negative ion generators, capable of producing high concentrations of negative ions and also offering air purification, are gradually becoming a hot topic in market research. Currently, purification devices that utilize the Leonard effect of water (the phenomenon where water droplets ionize the surrounding air when water flows onto a hard surface or breaks) to generate negative ions and perform air purification have been reported. These devices typically mimic the waterfall principle, using a water curtain or spray system to contact the air, aiming to achieve a three-in-one effect of humidification, purification, and negative ion generation. However, existing technologies still have shortcomings in practical applications:

[0003] The efficiency of particulate matter capture needs to be improved: Most existing equipment relies on the natural interception of water curtains or simple spray washing. For suspended particulate matter with small particle size in the air, such as PM2.5 or even PM0.3, the efficiency of capturing by collision of water curtains alone is low, and the airflow is prone to short-circuiting, resulting in some air that has not been fully washed being discharged directly, and the purification effect is not thorough.

[0004] Insufficient gas-liquid mixing leads to fluctuations in negative ion production: Traditional water curtain generators have a fixed structure, and the contact between water flow and air flow is mostly passive cross. Since the direction and speed of air flow cannot be actively adjusted, it is difficult to ensure that the air flow and water curtain have a continuous and stable intense collision within the entire contact surface, resulting in unstable negative ion excitation efficiency and easy formation of water-encapsulated gas or gas-flow short-circuiting phenomena.

[0005] In addition, existing equipment mostly adopts a single purification mechanism and lacks the synergistic combination of multiple separation technologies, making it difficult to achieve efficient and synergistic removal of complex pollutants such as particulate matter, aerosols, and microorganisms.

[0006] Therefore, how to design a multi-stage combined water-air separation water curtain air purification device that can achieve efficient particulate matter capture, stable excitation of high-concentration negative ions, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-stage combined water-air separation water curtain air purification device to solve the above-mentioned problems.

[0008] The present invention is implemented as follows: a multi-stage combined water-air separation water curtain air purification device includes a shell, in which a centrifugal filter tube, a negative oxygen ion generating chamber, a gas-liquid separator, an ultraviolet disinfection box, and a negative pressure machine are sequentially connected. The centrifugal filter tube is connected to the air inlet port of the shell, and the negative pressure machine is connected to the air outlet port of the shell.

[0009] The negative ion generating chamber is equipped with a water curtain washing mechanism for achieving gas-liquid mixing. The water curtain washing mechanism includes a stepped guide plate. Each side baffle of the stepped surface of the stepped guide plate is slidably connected to a guide slide. Each guide slide is rotatably connected to a counter-impact roller. The guide slide supports and guides the counter-impact roller, and all counter-impact rollers are in contact with the surface of the stepped guide plate. The stepped guide plate is also connected to an airflow guiding component. The airflow guiding component can guide the airflow and pass through the water curtain on the stepped guide plate, and the airflow guiding component can drive all the counter-impact rollers to reciprocate.

[0010] A water storage tank is provided at the bottom of the negative oxygen ion generating chamber. A filter tank for purifying and filtering sewage is provided on one side of the water storage tank. A water guide pipe is connected to the bottom of the stepped guide plate. The bottom of the water guide pipe is inserted into the filter tank. The filter tank is connected to a pumping system. The pumping system can transport the purified water to the upper side of the water curtain washing mechanism and the negative oxygen ion generating chamber.

[0011] The centrifugal filter tube is equipped with a centrifugal capture mechanism, which can create a vortex in the outside air and throw the particulate matter carried by the airflow into the water film on the inner wall of the centrifugal filter tube cavity.

[0012] Furthermore, the airflow guiding component includes a rotating rod. Each stepped surface of the stepped guide plate is rotatably connected to the rotating rod via an elastic torsion spring. The connection position between the rotating rod and the stepped surface of the stepped guide plate is sealed with a flexible material. Each rotating rod is fixedly connected to an air guide pipe. An air outlet is provided on the lower side of each stepped surface of the stepped guide plate. Two rows of interconnected air outlet holes are provided on the upper side of each air outlet. Each air guide pipe is provided with an air inlet and two air outlets. A filter screen for filtering particulate matter is provided at the air inlet of the air guide pipe. The two air outlets of the air guide pipe are respectively connected to the air outlet and the air outlet hole on one side of the stepped guide plate via flexible hoses.

[0013] Furthermore, a second vibrator is fixedly connected to the bottom of one of the air ducts, and all the air ducts are connected by a common connecting rod. The inner top surface of the air duct is rotatably connected to a guide plate through an elastic torsion spring.

[0014] Furthermore, one end of the rotating rod is provided with a guide groove, and a slider is slidably connected in the guide groove. One end of the counter-impact roller is rotatably connected to the slider.

[0015] Furthermore, the centrifugal capture mechanism includes a guide rod and a sliding sleeve. The guide rod is fixedly connected to the inner wall of the centrifugal filter tube, and the guide rod coincides with the axis of the centrifugal filter tube. The sliding seat of the sliding sleeve is inserted into and slidably connected in the guide rod, and a spring is connected between the sliding seat of the sliding sleeve and the guide rod. The sliding seat of the sliding sleeve is connected to a first vibrator that can drive the sliding sleeve to reciprocate along the guide rod. The sliding sleeve is spirally provided with a first spiral guide plate for guiding airflow along its length.

[0016] Furthermore, the pumping system includes a pump, the pumping pipe of which is connected to the filter tank, and the pumping outlet pipe of which is connected to the upper part of the stepped guide plate and a row of spray holes on the top surface of the centrifugal filter tube through a first guide pipe and a second guide pipe.

[0017] Furthermore, a second spiral guide plate is fixedly connected in the gas-liquid separator.

[0018] Furthermore, the upper and lower end faces of the inner side of the ultraviolet disinfection box are provided with partitions, all partitions are equally spaced, and ultraviolet lamps are provided between adjacent partitions.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This application effectively solves the problems of uneven airflow guidance leading to insufficient gas-liquid mixing, fluctuations in negative ion yield, and easy accumulation of impurities on the stepped horizontal surface in the prior art. Specifically, this application actively guides the airflow through the water curtain on the stepped guide plate at a specific angle using an airflow guiding component. The intense collision between the airflow and the water curtain ensures full contact and mixing between the airflow and the water curtain. This active guiding mechanism effectively solves the problems of airflow "short circuit" and "water encapsulating air", thereby stabilizing and improving the yield of negative oxygen ions and providing users with higher quality negative oxygen ion air.

[0021] 2. In the airflow guiding component of this application, the rotating rod connected by the elastic torsion spring allows the airflow guiding component to adaptively adjust the airflow direction, ensuring that the airflow continuously and stably passes through the water curtain within a specific angle range. This greatly enhances the intense collision effect between the airflow and the water curtain, achieving thorough mixing and washing of gas and liquid, and thus stably and efficiently stimulating high-concentration nano-level negative oxygen ions. More importantly, the air guide pipe is connected to the air outlet and two rows of interconnected air outlet holes on the stepped guide plate via a flexible hose. This multi-path, uniform air outlet design not only improves the uniformity of airflow and increases the uniformity of gas-liquid mixing, but also allows the airflow to impact the stepped horizontal surface of the stepped guide plate within a specific angle range, effectively flushing the deposited impurities into the water storage tank. This achieves the self-cleaning function of the stepped guide plate, avoiding the impact of impurity accumulation on the uniformity of the water curtain and the purification efficiency of the equipment, and significantly reducing maintenance frequency and costs.

[0022] 3. This application effectively solves the problems of limited airflow impact range and easy clogging of air outlets. By driving the guide plate to dynamically swing through the second vibrator, the airflow pressure and angle continuously change, significantly increasing the impact range of the airflow on the stepped horizontal surface of the stepped guide plate. This greatly improves the uniformity and efficiency of gas-liquid mixing, promoting the stable and efficient generation of negative oxygen ions. Simultaneously, this dynamic impact effectively cleans blockages in the air outlets, achieving a self-cleaning function, preventing impurity accumulation, extending the equipment's lifespan, and reducing maintenance costs. In conjunction with modules such as centrifugal filter tubes, negative oxygen ion generating chambers, gas-liquid separators, ultraviolet disinfection boxes, and negative pressure units, this equipment can provide a more comprehensive, efficient, and stable air purification effect.

[0023] 4. This application effectively solves the shortcomings of traditional centrifugal capture mechanisms in terms of vortex formation stability and particulate matter capture efficiency. The synergistic effect of the guide rod, sliding sleeve, first vibrator, and first spiral guide plate forces the air entering the centrifugal filter tube to form a more stable and stronger vortex. The first vibrator drives the sliding sleeve and its spiral guide plate to reciprocate. This dynamic disturbance effectively breaks the laminar flow state of the airflow, enhances the uniformity and intensity of the centrifugal force, and thus allows the particulate matter carried by the airflow, especially small-diameter suspended particulate matter, to be more thoroughly and evenly thrown towards the inner wall of the centrifugal filter tube cavity. Combined with the capillary microporous hydrophilic layer and dynamic water film capture layer on the inner wall of the centrifugal filter tube, the particulate matter can be strongly embedded in the water film, significantly improving the particulate matter capture efficiency and the reliability of the initial separation. This not only improves the overall air purification effect but also reduces the burden on subsequent purification modules and extends the service life of the equipment. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0036] like Figure 1 , Figure 3 as well as Figure 5 As shown, a multi-stage combined water-air separation water curtain air purification device according to an embodiment of the present invention includes a housing 1. A centrifugal filter tube 11, a negative oxygen ion generating chamber 12, a gas-liquid separator 13, an ultraviolet disinfection box 14, and a negative pressure unit 15 are sequentially connected within the housing 1. The centrifugal filter tube 11 is connected to the air inlet port of the housing 1, and the negative pressure unit 15 is connected to the air outlet port of the housing 1. Preferably, a U-shaped water seal pipe can be installed at the bottom drain outlet of the gas-liquid separator 13. The U-shaped water seal pipe utilizes the water column retained within its curved structure to form a dynamic seal.

[0037] The negative ion generating chamber 12 is equipped with a water curtain washing mechanism 6 for achieving gas-liquid mixing. The water curtain washing mechanism 6 includes a stepped guide plate 61. Each side baffle of the stepped surface of the stepped guide plate 61 is slidably connected to a guide slide 62. Each guide slide 62 is rotatably connected to a counter-impact roller 63. The guide slide 62 is used to support and guide the counter-impact roller 63. All counter-impact rollers 63 are in contact with the surface of the stepped guide plate 61. The stepped guide plate 61 is also connected to an airflow guiding component 65. The airflow guiding component 65 can guide the airflow and pass through the water curtain on the stepped guide plate 61. The airflow guiding component 65 can also drive all the counter-impact rollers 63 to reciprocate.

[0038] A water storage tank 3 is provided at the bottom of the negative oxygen ion generating chamber 12. A filter tank 4 for purifying and filtering sewage is provided on one side of the water storage tank 3. A water guide pipe 64 is connected to the lowest step horizontal surface of the stepped guide plate 61. The bottom of the water guide pipe 64 is inserted into the filter tank 4. The bottom port of the water guide pipe 64 is lower than the lowest working liquid level of the filter tank 4 to ensure that a water seal is formed to prevent odor from escaping. At the same time, the inner diameter of the water guide pipe 64 should meet the maximum wastewater flow requirements to avoid poor drainage. The filter tank 4 is connected to a pumping system 5. The pumping system 5 can transport the purified water to the upper side of the water curtain washing mechanism 6 and the negative oxygen ion generating chamber 12. A centrifugal capture mechanism 2 is provided in the centrifugal filter tube 11. The centrifugal capture mechanism 2 can make the outside air form a vortex and throw the particulate matter carried by the airflow into the water film on the inner wall of the centrifugal filter tube 11.

[0039] In this embodiment, the device employs a modular air handling process. Specifically, the outer casing 1 contains, in sequence, a centrifugal filter tube 11, a negative ion generating chamber 12, a gas-liquid separator 13, an ultraviolet disinfection box 14, and a negative pressure unit 15. The centrifugal filter tube 11 is connected to the air inlet of the outer casing 1, responsible for the initial pretreatment of the incoming external air; the negative pressure unit 15 is connected to the air outlet of the outer casing 1, creating negative pressure inside the device to drive air to flow sequentially through each functional module along a preset path. As an optional implementation, the modules can be connected by flanges or sealed sleeves to ensure the airtightness and continuity of the airflow. This series-connected modular design allows the air to undergo multi-stage purification, thereby improving the overall purification effect.

[0040] Secondly, in order to achieve efficient gas-liquid mixing and negative oxygen ion activation, a water curtain washing mechanism 6 is installed in the negative oxygen ion generating chamber 12. The core component of the water curtain washing mechanism 6 is a stepped guide plate 61, whose surface is designed to be multi-layered stepped, so that when water flows down from the top, it can form a continuous falling water curtain on each step.

[0041] Furthermore, to enhance the gas-liquid counterflow effect and aid in cleaning, guide slides 62 are slidably connected to one side baffle of the stepped facade of the stepped baffle 61, and counterflow rollers 63 are rotatably connected to each guide slide 62. All counterflow rollers 63 maintain contact with the surface of the stepped baffle 61. Alternatively, the guide slides 62 can be designed with grooves, and the counterflow rollers 63 are mounted on the guide slides 62 via their bearings, allowing limited sliding and rotation of the counterflow rollers 63 on the stepped facade. This configuration enables the counterflow rollers 63 to dynamically interact with the water curtain and airflow, thereby promoting gas-liquid mixing.

[0042] Furthermore, to optimize the contact efficiency between the airflow and the water curtain, the stepped guide plate 61 is also connected to an airflow guiding component 65. This airflow guiding component 65 can guide the airflow through the water curtain on the stepped guide plate 61 and can drive all the counter-rolling rollers 63 to reciprocate. This active airflow guidance and the movement of the counter-rolling rollers 63 ensure that the airflow can fully and evenly contact the water curtain, thereby improving washing efficiency and negative oxygen ion production.

[0043] Furthermore, to achieve water resource recycling and prevent impurity accumulation, a water storage tank 3 is installed at the bottom of the negative ion generating chamber 12 to collect wastewater after washing. A filter tank 4 for purifying and filtering wastewater is installed on one side of the water storage tank 3. A water guide pipe 64 is connected to the lowest step of the stepped guide plate 61, with its bottom inserted into the filter tank 4 to guide the wastewater to it. The filter tank 4 is connected to a pumping system 5, which can transport the purified water to the upper part of the water curtain washing mechanism 6 and the negative ion generating chamber 12. For example, the filter tank 4 can have multiple layers of filter screens or activated carbon filter cartridges built in for physical filtration and adsorption treatment of the wastewater. The pumping system 5 can be a simple water pump that transports the filtered water back to the top of the water curtain washing mechanism 6 through pipes, forming a closed-loop water circulation system.

[0044] Finally, to improve the particulate matter capture efficiency, a centrifugal capture mechanism 2 is provided in the centrifugal filter tube 11. This centrifugal capture mechanism 2 enables the outside air to form a high-speed rotating vortex after entering the centrifugal filter tube 11, and throws the particulate matter carried by the airflow into the water film on the inner wall of the centrifugal filter tube 11 under the action of centrifugal force. The inner wall of the centrifugal filter tube 11 is designed with a hydrophilic surface, and a small amount of water continuously flows along the wall to form a water film to capture the thrown-out particulate matter.

[0045] like Figure 5 and Figure 6As shown, in a preferred embodiment of the present invention, the airflow guiding component 65 includes a rotating rod 651. Each stepped surface of the stepped guide plate 61 is rotatably connected to the rotating rod 651 via an elastic torsion spring. The connection position between the rotating rod 651 and the stepped surface of the stepped guide plate 61 is sealed with a flexible material. Each rotating rod 651 is fixedly connected to an air guide pipe 652. An air outlet 66 is provided on the lower side of each stepped surface of the stepped guide plate 61. Two rows of interconnected air outlet holes 67 are provided on the upper side of each air outlet 66. Each air guide pipe 652 is provided with an air inlet and two air outlets. A filter screen for filtering particulate matter is provided at the air inlet of the air guide pipe 652. The two air outlets of the air guide pipe 652 are respectively connected to the air outlet 66 and the air outlet hole 67 on one side via flexible hoses.

[0046] In this embodiment, the airflow guiding component 65 is a mechanism for guiding the direction and flow of airflow. The rotating rod 651 enables the dynamic adjustment function of the airflow guiding component 65. One end of the elastic torsion spring is fixed and the other end is connected to the rotating rod 651, allowing the rotating rod 651 to rotate at a certain angle when subjected to airflow, and to return to its initial position after the airflow weakens or disappears. This connection method allows the rotating rod 651 to swing flexibly according to the dynamic changes of airflow, thereby achieving adaptive adjustment of the airflow direction.

[0047] The flexible material seal is designed to prevent moisture or impurities from leaking or seeping into the connection gap between the rotating rod 651 and the stepped guide plate 61. This flexible material can be selected from seals with good elasticity and water resistance, such as silicone rubber, EPDM rubber, or polyurethane, including sealing rings, gaskets, or flexible rubber strips. Its function is to ensure the airtightness of the negative ion generating chamber 12, prevent untreated air from short-circuiting, and prevent moisture corrosion of the rotating mechanism, thus extending the service life of the equipment.

[0048] The air duct 652 is a conduit for conveying and distributing airflow. It is fixedly connected to the rotating rod 651, meaning the orientation of the air duct 652 changes with the rotation of the rod 651, thus achieving precise control over the airflow direction. The air inlet of the air duct 652 receives airflow from upstream, while its two exhaust ports distribute the airflow along different paths. This design allows the airflow to be precisely guided to different positions on the stepped guide vane 61, enabling finer airflow control and distribution. A filter screen is used to initially filter particulate matter from the airflow before it enters the air duct 652, preventing larger particles from entering the air duct 652 and causing blockage or wear. A flexible hose connects the two exhaust ports of the air duct 652 to the exhaust ports 66 and 67 on the stepped guide vane 61. The flexibility of the hose allows the rotating rod 651 and the air duct 652 to remain connected during rotation, while avoiding stress concentration caused by a rigid connection.

[0049] The air outlets 66 are channels through which airflow enters the negative ion generating chamber 12 from the air guide pipe 652. These outlets 66 are located on the lower side of the stepped facade and are designed to guide the airflow to specific areas of the water curtain for full contact and counter-current. The air vents 67 are tiny holes that further disperse the airflow; they are located above the air outlets 66 and arranged in two rows that are interconnected. This design increases the contact area between the airflow and the water curtain and makes the airflow distribution more uniform.

[0050] The solution proposed in this application achieves precise airflow guidance and uniform distribution through the ingenious design of the airflow guiding component 65, thereby optimizing the gas-liquid mixing efficiency and the self-cleaning capability of the equipment. Specifically, the core of the airflow guiding component 65 is the rotating rod 651, which is rotatably connected to each stepped surface of the stepped guide plate 61 via an elastic torsion spring. This connection method allows the rotating rod 651 to swing flexibly according to the dynamic changes in airflow, ensuring that the airflow always passes through the water curtain at a specific angle range, avoiding uneven airflow distribution or short-circuiting phenomena that may occur with traditional fixed structures. To ensure the airtightness of the system and prevent water vapor corrosion, the connection between the rotating rod 651 and the stepped guide plate 61 is sealed with a flexible material. The air guide pipe 652, which is fixedly connected to the rotating rod 651, has an air inlet and two exhaust ports inside. A filter screen is installed at the air inlet to perform preliminary filtration of the incoming airflow, effectively preventing particulate matter from clogging the air guide pipe 652 and the subsequent air outlet 66 and air vent 67. The two exhaust ports of the air duct 652 are connected to the air outlet 66 and the air vent 67 on the stepped guide plate 61 via flexible hoses. The air outlet 66 is located on the lower side of the stepped facade, while two rows of interconnected air vents 67 are provided on its upper side. This multi-path distribution and dispersed air outlet design allows the airflow to be evenly distributed to different areas of the stepped guide plate 61, greatly improving the uniformity of airflow.

[0051] In the entire purification process, firstly, the air pretreated by the centrifugal filter tube 11 enters the negative oxygen ion generating chamber 12. The pumping system 5 transports the purified water from the storage tank 3 to the top of the stepped guide plate 61, forming a multi-layered, continuously cascading waterfall curtain. At this point, the airflow guiding component 65 plays a crucial role:

[0052] On the one hand, it precisely guides the airflow within a specific angle range, causing it to pass through these water curtains and violently collide with them. This active and uniform collision not only achieves thorough mixing and washing of the gas and liquid, but also more efficiently utilizes the Leonard effect to stimulate high concentrations of nanoscale negative oxygen ions.

[0053] On the other hand, the airflow impacts the stepped horizontal surface of the stepped guide plate 61 at a specific angle range. This impact force can effectively wash away impurities deposited on the stepped horizontal surface, causing them to be continuously carried downwards with the water flow and eventually collected in the reservoir 3.

[0054] Furthermore, the combined air outlet 66 and air outlet 67 enhance the uniformity and impact of the airflow, which not only improves the uniformity of gas-liquid mixing but also ensures the self-cleaning ability of the stepped guide plate 61, preventing the long-term accumulation of impurities.

[0055] Through the above structure and working mechanism, the solution of this application solves the problems of insufficient gas-liquid mixing and fluctuation of negative ion yield caused by uneven airflow in basic air purification equipment by optimizing airflow guidance and distribution. At the same time, it effectively avoids the accumulation of impurities on the stepped guide plate 61, and improves the self-cleaning ability and operational stability of the equipment.

[0056] like Figure 6 as well as Figure 8 As shown, in a preferred embodiment of the present invention, a second vibrator 653 is fixedly connected to the bottom of one of the air ducts 652, and all the air ducts 652 are connected by a common connecting rod 654. The inner top surface of the air duct 652 is rotatably connected to a guide plate 655 through an elastic torsion spring.

[0057] In this embodiment, the second vibrator 653 is a device for generating mechanical vibration. Its function is to provide vibrational energy and transmit it to the air duct 652, thereby driving the air guide plate 655 to oscillate. Specifically, the vibration generated by the second vibrator 653 is transmitted to the inner top surface through the wall of the air duct 652, causing the elastic torsion spring to deform periodically, thereby driving the air guide plate 655 to oscillate back and forth around its axis. The second vibrator 653 preferably adopts an eccentric wheel motor. The rotation of the motor drives the eccentric wheel to generate an unbalanced force, thereby producing periodic vibration. The function of the connecting rod 654 is to mechanically connect all the air ducts 652 together to ensure that they can move synchronously or transmit vibration.

[0058] The air guide plate 655 is a plate-like structure installed inside the air duct 652, and its main function is to change the direction and velocity of the airflow. The elastic torsion spring provides restoring force, allowing the air guide plate 655 to return to its initial position after being subjected to force or to maintain dynamic balance during vibration. One end of the elastic torsion spring is fixed to the inner top surface of the air duct 652, and the other end is fixed to the rotating shaft of the air guide plate 655. When the vibration frequency of the second vibrator 653 increases, its driving power supply frequency or voltage can be controlled to generate higher frequency vibrations, thereby increasing the swing amplitude of the air guide plate 655 through mechanical coupling.

[0059] The oscillation of the air guide plate 655 directly alters the path and force distribution of airflow through the outlets 66 and 67 of the stepped guide plate 61, resulting in dynamic changes in air pressure and airflow angle. This dynamically changing airflow can cover a larger area of ​​the stepped guide plate 61, thus interacting more effectively with the water curtain and sediment. Simultaneously, the dynamically changing air pressure and airflow angle can exert an impact force on particles that may clog the 67 outlets, thereby achieving self-cleaning.

[0060] The proposed solution cleverly combines a second vibrator 653, a connecting rod 654, and a guide plate 655 to form a mechanism for dynamically regulating airflow. Specifically, the second vibrator 653 acts as the vibration source, and its vibration is synchronously transmitted to all air ducts 652 via the connecting rod 654. The guide plate 655, connected to the top surface of the inner end of the air duct 652, oscillates at a certain frequency and amplitude under the action of vibration, aided by an elastic torsion spring. As the vibration frequency of the second vibrator 653 increases, the oscillation amplitude of the guide plate 655 increases accordingly, causing the airflow pressure and angle ejected from the outlets 66 and 67 of the stepped guide plate 61 to change dynamically and periodically, rather than remaining constant. This dynamically changing airflow can act on the stepped horizontal surface of the stepped guide plate 61 with a wider range and stronger impact force, thereby significantly increasing the contact area and counter-current intensity between the airflow and the water curtain, promoting thorough mixing of gas and liquid, and further stimulating high concentrations of negative oxygen ions. Furthermore, this dynamic impact can effectively flush away impurities that may accumulate on the surface of the stepped guide plate 61 and impact blockages inside or at the edges of the air outlet 67, preventing their accumulation and thus achieving the self-cleaning function of the equipment. Compared with the fixed airflow guidance method in the prior art, this solution introduces dynamic vibration and the oscillation of the guide plate 655, making the airflow impact on the water curtain more comprehensive and in-depth. This not only improves the uniformity of gas-liquid mixing but also solves the long-standing self-cleaning problem of water curtain purification equipment, significantly improving the operational stability and purification efficiency of the equipment.

[0061] like Figure 7 As shown, in a preferred embodiment of the present invention, one end of the rotating rod 651 is provided with a guide groove 7, and a slider 8 is slidably connected in the guide groove 7. One end of the counter-impact roller 63 is rotatably connected to the slider 8.

[0062] In this embodiment, a guide groove 7 is provided at one end of the rotating rod 651. The function of the guide groove 7 is to provide a precise motion trajectory for the subsequent slider 8, ensuring its stable movement in a specific direction. Inside the guide groove 7, the slider 8 is slidably connected. The slider 8 is a component that can reciprocate or slide unidirectionally along the trajectory of the guide groove 7. In addition, one end of the counter-impact roller 63 is rotatably connected to the slider 8. This connection method allows the counter-impact roller 63 to rotate freely around its own axis while maintaining connection with the slider 8.

[0063] In this embodiment, by providing a guide groove 7 at one end of the rotating rod 651 and allowing the slider 8 to slide within it, the impact roller 63 gains an additional degree of freedom, namely, it can be finely adjusted within the range defined by the guide groove 7. When the impact roller 63 rolls on the surface of the stepped guide plate 61, if it encounters unevenness or needs to adjust the contact pressure, the slider 8 can slide in the guide groove 7, thereby allowing the impact roller 63 to make small displacement compensations in directions perpendicular to or parallel to the surface of the stepped guide plate 61, maintaining the contact stability between the impact roller 63 and the stepped guide plate 61.

[0064] The solution proposed in this application establishes a dynamically adjustable connection between the anti-roller 63 and the rotating rod 651, enabling the anti-roller 63 to better adapt to the surface condition of the stepped guide plate 61 and the dynamic changes during equipment operation. In the water curtain washing mechanism 6, when the rotating rod 651 rotates, it pushes the slider 8 to slide in the guide groove 7. At this time, the slider 8 drives the connected anti-roller 63 to roll vertically. The rotational connection between the anti-roller 63 and the slider 8 ensures that the anti-roller 63 can rotate continuously to complete its functions of rinsing and uniform water curtain. This design cleverly combines the rolling function of the anti-roller 63 with dynamic adaptive capability. Especially when the second vibrator 653 is working, the vibration it generates is transmitted to the air guide pipe 652 and the connecting rod 654, thus affecting the rotating rod 651. Without this adaptive mechanism, the vibration may cause the anti-roller 63 to frequently jump off the surface of the stepped guide plate 61, affecting the cleaning effect. In this design, the cooperation between the guide groove 7 and the slider 8 enables the counter-impact roller 63 to absorb and buffer these vibrations, and always maintain stable contact with the stepped guide plate 61. This ensures that under dynamic working conditions, the counter-impact roller 63 can still efficiently flush away impurities and maintain the uniformity of the water curtain.

[0065] like Figure 2As shown, in a preferred embodiment of the present invention, the centrifugal capture mechanism 2 includes a guide rod 21 and a sliding sleeve 22. The guide rod 21 is fixedly connected to the inner wall of the centrifugal filter tube 11, and the axis of the guide rod 21 coincides with that of the centrifugal filter tube 11. The sliding seat of the sliding sleeve 22 is inserted into and slidably connected to the guide rod 21, and a spring is connected between the sliding seat of the sliding sleeve 22 and the guide rod 21. The sliding seat of the sliding sleeve 22 is connected to a first vibrator capable of driving the sliding sleeve 22 to reciprocate along the guide rod 21. The sliding sleeve 22 is spirally equipped with a first spiral guide plate 23 for guiding airflow along its length. When the outside air enters the centrifugal filter tube 11 under negative pressure, it forms a high-speed rotating vortex. The particulate matter carried by the airflow is thrown towards the inner wall of the centrifugal filter tube 11 cavity under the action of centrifugal force. The inner wall of the centrifugal filter tube 11 is covered with a capillary microporous hydrophilic layer. Circulating water flows down the wall to form a dynamic "water film capture layer". The particulate matter is forcefully thrown into the water film and captured under the action of centrifugal force, realizing the first efficient separation of air and particulate matter.

[0066] In this embodiment, the guide rod 21 serves as the core support component of the centrifugal capture mechanism 2, and its main function is to provide a stable sliding path and positioning reference for the sliding sleeve 22. The sliding sleeve 22 is a sleeve-shaped structure capable of reciprocating along the guide rod 21, and its interior is provided with a sliding seat that cooperates with the guide rod 21.

[0067] The sliding seat of the sliding sleeve 22 is inserted into and slidably connected to the guide rod 21. This connection allows the sliding sleeve 22 to perform linear reciprocating motion on the guide rod 21. A spring connects the sliding seat of the sliding sleeve 22 and the guide rod 21. The spring's function here is to provide elastic restoring force, ensuring that the sliding sleeve 22 can reciprocate smoothly during vibration and reducing vibration impact. The first vibrator is the core component for realizing the dynamic reciprocating motion of the sliding sleeve 22. Its function is to generate periodic mechanical vibration and transmit the vibration to the sliding sleeve 22. The first vibrator can be an eccentric wheel vibrator, in which a motor drives the eccentric wheel to rotate at high speed, generating an unbalanced force, thereby causing vibration.

[0068] The sliding sleeve 22 is spirally provided with a first spiral guide plate 23 for guiding airflow along its length. The first spiral guide plate 23 is a key structure for guiding airflow to form a stable vortex. Its function is to force the incoming air to flow along the spiral path, thereby efficiently forming a high-speed rotating vortex.

[0069] The inner wall of the centrifugal filter tube 11 is covered with a capillary microporous hydrophilic layer, which is a coating material with a microporous structure and a hydrophilic surface. Its function is to enhance the adhesion of the water film, allowing water to spread evenly on the tube wall and form a stable water film. This material can be hydrophilic ceramics, polymer materials, or specially treated metal surfaces.

[0070] The solution presented in this application significantly improves the particulate matter capture efficiency through its ingenious structural design and dynamic operating mechanism. The core of this centrifugal capture mechanism 2 lies in the synergistic effect of the guide rod 21, the sliding sleeve 22, the first vibrator, and the first spiral guide plate 23.

[0071] When the equipment starts, the negative pressure unit 15 generates negative pressure, drawing outside air into the centrifugal filter tube 11. Upon entering the centrifugal filter tube 11, the air is first forced into a high-speed rotating vortex by the first spiral guide plate 23. During this process, the first vibrator drives the sliding sleeve 22 and its first spiral guide plate 23 to reciprocate along the guide rod 21. This dynamic vibration causes the vortex flow field to be periodically disturbed, rather than static, thereby enhancing the turbulence intensity and the uniformity of centrifugal force. Particulate matter carried in the airflow is more effectively thrown towards the inner wall of the centrifugal filter tube 11 under the enhanced centrifugal force.

[0072] The inner wall of the centrifugal filter tube 11 is covered with a capillary microporous hydrophilic layer, and circulating water supplied by the pumping system 5 flows down the wall to form a dynamic "water film capture layer." The powerful centrifugal force assisted by vibration allows particles to be more deeply and firmly embedded in the dynamic water film and captured when thrown against the tube wall. This combination of dynamic vibration and spiral flow not only ensures the stable formation of eddies but also effectively overcomes the "short-circuit" phenomenon and incomplete particle capture problems that may occur in traditional centrifugal separation through continuous disturbance. In particular, the capture efficiency is significantly improved for small-diameter suspended particles. Through this mechanism, the first efficient separation of air and particles is achieved, reducing the burden on the subsequent negative ion generation chamber 12 and water curtain washing mechanism 6, and ensuring the efficient operation of the entire air purification equipment.

[0073] like Figure 4 As shown, in a preferred embodiment of the present invention, the pumping system 5 includes a pumping pump 51, the pumping pipe of the pumping pump 51 is connected to the filter tank 4, and the outlet pipe of the pumping pump 51 is connected to the upper part of the stepped guide plate 61 and a row of spray holes 17 on the inner top surface of the centrifugal filter tube 11 through a first guide pipe 52 and a second guide pipe 53 respectively.

[0074] In this embodiment, by optimizing the structure of the pumping system 5, precise distribution and delivery of water flow are achieved. The pump 51, as the core power source, draws purified water from the filter tank 4, ensuring the cleanliness of the water source and reducing the risk of impurity introduction and clogging at the source. Subsequently, the outlet pipe of the pump 51 splits the water flow, with one portion precisely delivered to the upper part of the stepped guide plate 61 via the first guide pipe 52. This design ensures that the water flow can uniformly and continuously cover the stepped guide plate 61, forming a stable water curtain, thereby maximizing the contact area between the airflow and the water curtain, improving gas-liquid mixing efficiency, and promoting the Leonard effect to generate high concentrations of negative oxygen ions. Simultaneously, the continuous scouring of the stepped guide plate 61 surface by the water flow helps remove deposited impurities, effectively preventing clogging of the water curtain structure. The other portion of the water flow is delivered through the second guide pipe 53 to a row of spray holes 17 on the inner top surface of the centrifugal filter tube 11. The spray nozzle 17 evenly sprays water onto the inner wall of the centrifugal filter tube 11, forming a dynamic "water film capture layer." This water film works synergistically with the centrifugal capture mechanism 2 to efficiently capture particles thrown against the tube wall by centrifugal force and carry them away with the water flow, significantly improving particle capture efficiency. Furthermore, the continuous water film effectively prevents scale buildup on the inner wall of the centrifugal filter tube 11 due to dryness. This branched, precise water supply design ensures that both the water curtain washing mechanism 6 and the centrifugal capture mechanism 2 receive sufficient and uniform water, maximizing their purification efficiency and ensuring the efficient and stable operation of the entire multi-stage combined water-air separation water curtain air purification equipment.

[0075] like Figure 3 As shown, in a preferred embodiment of the present invention, a second spiral guide plate 9 is fixedly connected in the gas-liquid separator 13.

[0076] In this embodiment, the present application's solution uses a second spiral guide plate 9 fixedly connected to the gas-liquid separator 13. This allows the airflow carrying a large amount of water mist from the negative oxygen ion generating chamber 12 to be forcibly guided by the second spiral guide plate 9 upon entering the gas-liquid separator 13, forming a high-speed rotating vortex. Under the action of the vortex, because the density of water droplets is much greater than that of air, the water droplets are thrown towards the inner wall of the gas-liquid separator 13 under the action of centrifugal force. The water droplets thrown towards the inner wall will collect along the wall surface and flow downwards, eventually being discharged, while the relatively dry gas continues to flow upwards or forwards, leaving the gas-liquid separator 13. This fixed connection method ensures that the second spiral guide plate 9 can maintain a stable structure and guiding effect under the impact of airflow, thereby continuously and efficiently performing gas-liquid separation. In this way, the water vapor content in the airflow can be effectively reduced, providing drier gas for the subsequent ultraviolet disinfection box 14 and negative pressure machine 15. This avoids water vapor corroding the ultraviolet lamp 16 and damaging the negative pressure machine 15, ensuring the long-term stable operation of the equipment and the overall purification effect.

[0077] like Figure 9 As shown, in a preferred embodiment of the present invention, the upper and lower end faces of the inner side of the ultraviolet disinfection box 14 are provided with partitions 10. All partitions 10 are equally spaced, and ultraviolet lamps 16 are provided between adjacent partitions 10. A continuous curved flow channel is formed in the ultraviolet disinfection box 14 through each partition 10. The partitions 10 are made of high reflectivity material, or the surface of the partitions 10 is coated with an ultraviolet reflective coating, so that the ultraviolet light is reflected multiple times in the curved channel, ensuring that the airflow can be fully irradiated in all directions.

[0078] In this embodiment, the solution of this application optimizes the internal structure of the ultraviolet disinfection chamber 14 to ensure that the airflow is fully exposed to ultraviolet light during the disinfection process, thus solving the problem of insufficient disinfection. Specifically, in the multi-stage combined water-air separation water curtain air purification device, the air undergoes preliminary particulate matter separation through the centrifugal capture mechanism 2 of the centrifugal filter tube 11, gas-liquid mixing, negative oxygen ion activation, and further washing through the water curtain washing mechanism 6 of the negative oxygen ion generation chamber 12, and water-air separation through the gas-liquid separator 13 before entering the ultraviolet disinfection chamber 14. In the ultraviolet disinfection chamber 14, partitions 10 are provided on both the upper and lower inner surfaces, and all partitions 10 are equally spaced, so the forced airflow no longer passes through rapidly along a straight path. Instead, the airflow is guided to form a continuous curved guide channel. This curved channel design significantly prolongs the residence time of the airflow in the ultraviolet disinfection chamber 14. At the same time, since ultraviolet lamps 16 are provided between adjacent partitions 10, it is ensured that the airflow is continuously and evenly exposed to ultraviolet light when passing through each curved channel. This structural layout ensures full contact between airflow and ultraviolet light, avoiding the "short circuit" phenomenon and disinfection blind spots that may occur in traditional disinfection boxes. In this way, the ultraviolet disinfection box 14 can efficiently and thoroughly kill bacteria, viruses, and other microorganisms in the air, ensuring that the air discharged from the equipment's outlet is not only clean but also fully disinfected. This design seamlessly integrates with the entire purification process of the multi-stage combined water-air separation water curtain air purification equipment. Under the suction action of the negative pressure unit 15, it ensures that the air, after centrifugal filtration, water curtain washing, and gas-liquid separation, finally undergoes deep purification and disinfection in the ultraviolet disinfection box 14, forming a complete and efficient air handling chain.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
