Technical Field
[0001] This invention relates to the field of air purification equipment, and more particularly to a liquid-based air circulation purification device. Background Technology
[0002] Existing air purification technologies, such as physical filtration, chemical adsorption, and catalytic oxidation, while effective in removing particulate matter, chemical pollutants, and microorganisms, still have limitations in adapting to diverse purification scenarios. Traditional filters are prone to clogging and require frequent replacement. Chemical adsorption and catalytic technologies have limited effectiveness in treating various gaseous pollutants, especially under resource constraints or special environments (such as microgravity conditions), where performance is difficult to maintain consistently. In various scenarios, purification equipment needs to handle multiple pollutants while balancing high efficiency, durability, and low maintenance. However, traditional technologies struggle to simultaneously meet these diverse requirements.
[0003] Liquid-gated technology achieves efficient capture and release of pollutants through a controllable liquid interface, possesses self-cleaning capabilities, and effectively avoids the clogging problems of traditional filters. Liquid membranes exhibit greater adaptability in complex environments and can adapt to the characteristics of different pollutants by adjusting the liquid composition. Despite the numerous advantages of liquid-gated technology, dedicated purification equipment has not yet been developed, with challenges lying in achieving uniform solid-liquid mixing, self-cleaning, and liquid recycling.

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.
[0026] This embodiment provides a liquid-based air circulation purification device to solve the above-mentioned technical problems. The device includes a housing 9 and a device body placed inside the housing 9. The device body includes a power system, a filtration system 19, a drive system, a control system, a wetting and recovery system 15, a sealing mechanism, and a liquid storage tank 22 located at the bottom of the device body. The wetting and recovery system 15 integrates the spraying mechanism and the liquid recovery mechanism into one unit.
[0027] The power system uses a fan to provide airflow power. The fan can be an axial fan or a centrifugal fan, and the appropriate airflow configuration can be selected according to actual needs. The power system also includes an air guide shroud and a filter baffle 24. The air guide shroud is used to guide airflow and optimize airflow efficiency; the filter baffle 24 is used to prevent large objects from entering the system, ensuring the normal operation of the equipment and avoiding damage to the fan or other critical components.
[0028] The outer casing 9 is equipped with a human-machine interface 25 and ventilation holes on all four sides. It also has casters at the bottom for easy movement and handling. A mounting bracket 1 is provided on the inner wall of the outer casing 9. The device body includes a mounting base 2, which is connected to the outer casing 9 via the mounting bracket 1. A fan mounting hole 10 is installed on the mounting base 2. The fan is positioned above and concentrically with the mounting base 2, and the motor driving the fan is located at the center of the mounting base 2.
[0029] The device body also includes a fixed bracket 20, which is located below the fixed base 2. The filtration system 19 is installed in the internal space enclosed by the fixed bracket 20. The center of the filtration system 19 is connected to the centrifugal motor of the drive system to achieve coaxial transmission. The filter screen of the filtration system 19 rotates around the axis under the action of the centrifugal motor, and the rotation speed can be controlled by the speed of the centrifugal motor, switching between low and high speed. A solid-phase filter layer is attached to the filter screen of the filtration system 19, and the solid-phase filter layer is made of solid porous material. At the same time, a negative ion generator can be added to the front or rear side of the filter screen in this embodiment to further enhance the purification effect. The filter screen can be grounded to improve its electrostatic adsorption capacity, thereby improving the filtration effect on fine particulate matter.
[0030] The filtration system 19 is coaxially fitted with an annular wetting and recovery system 15. The inner side of the wetting and recovery system 15 is provided with evenly distributed nozzles 17. The wetting and recovery system 15 is connected to the water pumps in the purified liquid area and the polluted liquid area of the liquid storage tank 22 through flexible pipelines. The wetting and recovery system 15 draws purified liquid through the water pump and sprays the purified liquid onto the filtration system 19 through the nozzles 17. The purified liquid and the porous material on the filter screen combine to form a filtration system, thereby purifying the air introduced by the fan.
[0031] To ensure that the purified liquid is evenly sprayed onto the filtration system 19, the wetting and recovery system 15 moves up and down along the height of the filtration system 19 under the action of the drive system. Specifically, the fixed base 2 is provided with a coupling 11, which is connected to a transmission screw 12. The transmission screw 12 is arranged along the height of the filtration system 19, and the lifting motor of the drive system is connected to the transmission screw 12 through the coupling 11. It also includes a packaging chassis, the lower end of the transmission screw 12 is fixed to the packaging chassis, and an optical axis 13 parallel to the transmission screw 12 is provided between the fixed base 2 and the packaging chassis. A bearing sleeve 14 is installed on the optical axis 13. The wetting recovery system 15 is connected to the transmission screw and the bearing sleeve 14. The lifting motor drives the wetting recovery system 15 to move up and down along the optical axis 13 through the transmission screw, so that the wetting recovery system 15 can move up and down under the action of the lifting motor. In conjunction with the rotation of the filtration system 19, the purified liquid is evenly sprayed onto the filtration system 19 and helps the purified liquid to be evenly dispersed in the solid porous material.
[0032] To ensure that the wetting and recovery structure does not exceed a predetermined range during movement, thereby avoiding mechanical damage and ensuring the stability and safety of the equipment, a photoelectric baffle 23 is also provided on the wetting and recovery system 15. This baffle can locate the position of the wetting and recovery system 15, thus enabling precise control of the displacement range.
[0033] A camera can also be added to the wetting and recovery system 15 for real-time monitoring of the liquid spraying and recovery process. Through the human-machine interface 25, users can view real-time images and assess the liquid-solid mixture to optimize operational performance. As a simple alternative to this embodiment, the spraying mechanism and recovery mechanism of the wetting and recovery system can also be divided into two independent mechanisms.
[0034] The wetting and recovery system 15 is surrounded by a sealing mechanism. This sealing mechanism can switch between an open and a closed state under the action of the drive system, allowing the device to switch between purification and recovery processes. When the sealing mechanism is open, the filtration system 19 rotates at low speed, and the wetting and recovery system 15 moves up and down along the height of the filtration system 19 under the action of the drive system, spraying purification liquid onto the filtration system 19. This purification liquid, combined with the solid-phase filter layer, is used to purify the air introduced by the power system. When the sealing mechanism is closed, the wetting and recovery system 15 is in contact with the inner wall of the sealing mechanism, and the filtration system 19 rotates at high speed, causing the filtered contaminated liquid to fall into the wetting and recovery system 15 for recovery under centrifugal force. The contaminated liquid falling into the wetting and recovery system 15 is pumped by a water pump to the contaminated liquid area of the storage tank 22 for recovery.
[0035] Specifically, the closing mechanism consists of six closing baffles 21 evenly distributed on the outside of the filtration system 19. A ring-shaped transmission gear ring 4 is mounted on the fixed base 2. The fixed base 2 also has multiple transmission gears 3 meshing with the transmission gear ring 4. The transmission gear ring 4 rotates under the drive of a drive gear 5, which in turn drives the transmission gears 3. The drive gear 5 is driven by a drive motor 6. The upper end of the closing baffle 21 is mounted on the bottom of the fixed base 2 and connected to the transmission gears 3. The lower end of the closing baffle 21 passes through a hole in the bottom of the fixed bracket 20 and is rotatably connected to the fixed bracket 20. The drive gear 5 drives the transmission gear ring 4 to rotate, thereby driving the transmission gears 3 to rotate. The transmission gears 3 are connected to the closing baffles 21, thus allowing the closing baffles 21 to open and close around the fixed bracket 20 on the outside of the filtration system 19. A flexible material is provided on the outside of the wetting recovery system 15. When the closing baffles 21 are closed, the flexible material on the outside of the wetting recovery system 15 allows it to fit tightly against the inside of the closing baffles 21.
[0036] The control system includes a microcontroller minimum system, sensor communication circuit, screen communication circuit, motor drive circuit, relay drive circuit, host computer communication circuit, and power management circuit. It is used to control the operation of various mechanisms and systems within the purification device, ensuring coordinated system operation. Simultaneously, the control system is responsible for data transmission and real-time display, providing a user-friendly interface, real-time monitoring of equipment status, and optimizing the control and adjustment of the purification process.
[0037] When the purification equipment is in the purification process, the control system controls the drive gear 5 to rotate, thereby opening the closed baffle 21 to ensure air circulation. Simultaneously, the control system activates the centrifugal motor and the lifting motor. The filtration system 19 rotates at low speed under the action of the centrifugal motor, and the wetting and recovery system 15 moves up and down along the height of the filtration system 19 under the action of the lifting motor, spraying purification liquid onto the filtration system 19. The purification liquid is evenly sprayed onto the filter screen of the filtration system 19 and combines with the porous material thereto to form a filtration system. At this time, the user can view real-time images and assess the combination of purification liquid and solids through the human-machine interface 25 on the outer casing 9. The fan of the power system introduces air into the purification equipment, which, after being filtered by the filtration system formed by the purification liquid and porous material, flows into the air outside the equipment through the ventilation holes. The purification liquid can be selected and replaced with different components according to the characteristics of different pollutants in the air. After filtration, the purification liquid absorbs pollutants from the air to form a polluted liquid.
[0038] When contaminated liquid needs to be recovered, the user can switch the purification equipment to the recovery process. The control system controls the drive gear 5 to rotate, thereby closing the baffle 21 to form a sealed chamber, enclosing the filtration system 19 inside. Simultaneously, the control system controls the centrifugal motor and the lifting motor. The filtration system 19 rotates at high speed under the action of the centrifugal motor, and the wetting recovery system 15 is positioned at the recovery location under the action of the lifting motor. The outer wall of the wetting recovery system 15 is tightly attached to the baffle 21, preventing the contaminated liquid from being thrown out of the equipment. Under the action of centrifugal force and the obstruction of the baffle 21, the contaminated liquid falls onto the wetting recovery system 15. The wetting recovery system 15 has an annular groove to catch the contaminated liquid. The contaminated liquid falling into the wetting recovery system 15 is then transported to the contaminated liquid area of the storage tank 22 by a water pump, thus completing the recovery.
[0039] Furthermore, corresponding sensors can be placed in the liquid storage tank 22 to detect the type of pollutants in the contaminated liquid. The signals collected by the sensors are transmitted to the control unit of the control system, thereby realizing real-time monitoring and treatment optimization of pollutants, and improving purification efficiency and flexibility.
[0040] The liquid-based air circulation purification device of this embodiment can realize the construction of a liquid gated purification system by setting up a filtration system 19, a wetting and recovery system 15, a sealing mechanism, a control system and a power system. The cooperation between the filtration system 19 and the wetting and recovery system 15 can achieve uniform compounding of liquid and porous material in various scenarios and realize recovery, which can achieve the goal of not replacing the filter membrane. In addition, by adjusting different liquids, it can achieve multi-functional and multi-field purification, improving air purification efficiency and functional diversity.
