Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and particularly relates to a water medium atomized agglomerate air purification device and a purification method. Background Art

[0002] With the acceleration of the industrialization process, the problem of air pollution has become increasingly severe. In particular, pollutants such as PM2.5, formaldehyde, benzene series substances, and bacteria pose a serious threat to human health. Traditional air purification technologies have the following limitations: Single function defect: Although the HEPA filter technology can filter particulate matter, it cannot decompose gaseous pollutants (such as formaldehyde).

[0003] Insufficient collaborative treatment: Existing technologies are mostly designed for single pollutants and it is difficult to achieve the collaborative purification of multiple pollutants (particulate matter, organic matter, microorganisms). For example, although the atomization technology can adsorb particulate matter through water molecules, it lacks the ability to decompose volatile organic compounds (VOCs).

[0004] Therefore, there is an urgent need for an air purification technology that integrates adsorption, catalysis, and sterilization functions. Summary of the Invention

[0028] The following is a detailed description of the present invention with reference to the accompanying drawings: A water - medium atomized granule air purification device of the present invention includes a purification chamber 1 and a liquid storage tank 12. A spiral purification air duct 21 is arranged in the purification chamber 1. The spiral purification air duct 21 can extend the contact time between the granules and PM2.5. The inlet end of the purification air duct 21 is connected to an air inlet pipe 2. A first fan 3 is connected to the air inlet pipe 2. A granule bin 4 is arranged at the air inlet pipe 2. The discharge port of the granule bin 4 is connected to the air inlet pipe 2. The top of the granule bin 4 is connected to a first cyclone separator 5. A hot air duct 7 is arranged at the inlet end of the first cyclone separator 5. The hot air duct 7 is connected to a hot air blower 8. An atomizer 9 connected to the hot air duct 7 is arranged at the hot air duct 7. The atomizer 9 is connected to the liquid storage tank 12 through a water replenishing pipe 10 and a water pump 11. A stirring shaft 13 is arranged in the liquid storage tank 12 to prevent the precipitation of the water - medium solution and keep the water - medium solution homogeneous. The outlet end of the purification air duct 21 is connected to an electrostatic chamber 14. An electrostatic plate 15 is arranged in the electrostatic chamber 14. The outlet end of the electrostatic chamber 14 is connected to an ultraviolet disinfection chamber. Ultraviolet lamps 17 are arranged on the side wall of the ultraviolet chamber 16. The outlet end of the ultraviolet disinfection chamber is connected to the inlet end of a second cyclone separator 19 through a second fan 18. The bottom of the second cyclone separator 19 is connected to a collection bin 20.

[0029] Diversion grooves are arranged at the bottoms of both the granule bin 4 and the collection bin 20. The bottom of the diversion groove is connected to a screw conveyor. The discharge port of the screw conveyor at the granule bin 4 is connected to the air inlet pipe 2.

[0030] The air outlet of the first cyclone separator 5 is connected to an exhaust pipe 6 for discharging the humid and hot gas. As a preferred solution, the exhaust pipe 6 can be dried through a filter screen with a desiccant and then input into the hot air blower 8 for recycling to reduce energy consumption.

[0031] A PM2.5 sensor 22 and a VOCs sensor 23 are arranged at the air outlet of the second cyclone separator 19 for detecting the air purification effect.

[0032] A purification method of a water - medium atomized granule air purification device is as follows: Granule preparation: Nanometer titanium dioxide, activated carbon powder, quaternary ammonium salt bactericide and silicon source precursor are dispersed in deionized water to form a homogeneous water - medium solution and added to the liquid storage tank 12. The water - medium solution is pumped into the atomizer 9 by the water pump 11, atomized by the atomizer 9 and enters the hot air duct 7. The atomized liquid droplets are dried by 200 °C hot air, so that the atomized liquid droplets are quickly dehydrated to form porous granules, improving the specific surface area and adsorption activity. The generated granules fall into the granule bin 4 after being separated by the first cyclone separator 5. The granules can be sent into the air inlet pipe 2 through the transportation of the screw conveyor for air purification. The motor speed of the screw conveyor at the granule bin 4 can be controlled to adjust the addition amount of the granules. Purification stage: The agglomerates initially adsorb PM2.5 in the air in the purification air duct 21; in the electrostatic chamber 14, the collision between PM2.5 and the agglomerates is increased through the action of static electricity to help the agglomerates further adsorb PM2.5; in the ultraviolet chamber 16, ultraviolet rays sterilize the air and at the same time activate titanium dioxide to decompose formaldehyde and benzene series; during the purification stage, the agglomerates release quaternary ammonium salts for sterilization; Particle recovery: The purified particles fall into the collection bin 20 through the separation of the second cyclone separator 19. The agglomerates in the collection bin 20 can be recycled after treatment. The preferred treatment method is microwave regeneration, that is, the temperature inside the agglomerates is increased by microwave irradiation at 2.45 GHz to desorb pollutants and restore activity, so as to be recycled.

[0033] Preferably, the silicon source precursor is sodium silicate.

[0034] Preferably, the working voltage of the electrostatic plate 15 is 500 - 1500V.

[0035] The air purification effect can be monitored through the PM2.5 sensor 22 and the VOCs sensor 23. If the detected value is greater than the preset value, the agglomerates collected in the collection bin 20 cannot be recycled.
