The present invention has been filed in "Wet purification system for automobile exhaust gas using a centrifugal impeller", Korean Utility Model Application No. 20-2002-0033201 (the same applicant and inventor), the structure and operating principle of purifying air more efficiently Patent application of “centrifugal type air purifier”, patent registration No. 20-0328651 (Technology Evaluation Confirmation Registration) and dual patent publication No. 10-2004-0043138 and “Air purifier using centrifugal impeller”, patent Invention for miniaturization and lightening structure to have a commercial property based on Publication No. 10-2004-0099193 (same applicant and inventor), after collecting the bacteria, dust, fine particles and other contaminants contained in the air using the washing water It is based on aerodynamics that generate centrifugal force using a centrifugal impeller and a spiral structure that are rotated by an electric motor. Therefore, based on the specific gravity difference between gas and liquid (1: 1000), the air is centrifuged from the liquid contaminated water which collected the air pollutants in the collection chamber to maintain 99.9% of air purification efficiency without a solid filter for a long time. It is.

The present invention primarily collects the fine particulate dust, harmful gas, odor particles, pathogens, and bacteria in the air by using the washing water, and secondly by using the specific gravity difference (1: 1000) between gas and liquid. Centrifugal purification of the cleansing water that collects pollutants in the air, using centrifugal impeller that rotates at high speed. It relates to an air purifier of.

Atmospheric air contains bacteria, pathogens, sand, harmful gases, smoke, dust, oil, moisture, tire dust, pollen, and pollutants including fine dust and odor particles smaller than 0.1 μm in size.

The present invention primarily collects the fine particulate dust, harmful gas, odor particles, pathogens, and bacteria in the air by using the washing water, and secondly by using the difference in specific gravity between gas and liquid (1: 1000). In order to purify the air by centrifugation of the contaminated washing water in the air, the centrifugal impeller or the spiral groove can be used to generate the air in a vortex having a centrifugal force in the air.

Conventional air purification technology generally uses a bag filter in the form of a solid, but it does not completely collect and purify the fine particulate dust, and when air containing dust is attracted, it accumulates on the surface of the filter cloth. This is rapidly deteriorating and becoming a breeding ground for pathogens or bacteria. Therefore, there is a problem of maintenance due to regular replacement, and it is becoming a major cause of global environmental pollution by generating secondary environmental pollutants due to discarded filter nonwoven fabric. .

 In addition, the air purification efficiency of the air purifier including photocatalyst, electrostatic precipitating, and plasma is low, and the negative ion generating air purifier is known to have side effects of ozone generation, which is harmful to human health.

More conventional dry centrifugal air purifiers have a theoretical air purifying efficiency of 85% and are impossible to collect and purify fine particulate dust, pollen, tobacco smoke, and harmful gases with a particle size of 5 μm or less. It is not suitable for industrial clean rooms that require 99.9% purification efficiency.

On the other hand, there is a method of purifying the air by the viscous adhesion of water by attracting the air flow in the conventional wet air purifier by the two-dimensional water film surface contact. Therefore, only contaminants in the air in contact with the water film surface area are purified by the viscous adhesion of water, and most of the contaminants that do not contact the water film surface area are not purified, resulting in low air purification efficiency of 85% and containing excessive moisture. There was a problem that the air is discharged to corrode the precision equipment. More conventional wet air purifier can purify fine dust of 0.1μm size, but it is not sanitary because pathogens and microorganisms do not have their own sterilizing ability. It is not suitable for industrial clean room and hospital facilities that require efficiency.

On the other hand, the conventional humidifier combined air cleaner or anion generating air cleaner using water traps pollutants in the air with moisture and has an anion generating effect by the water molecular collision method, but it also comes with moisture containing pollutants and exhaust air. Since it comes out together, the actual air purification effect is very low, and it is known to be more harmful to human health or health since it is accompanied by pollutants in the moisture.

The present invention is to improve the conventional problems as described above, and to clean the contaminants including air bacteria and dust by centrifugation using a specific gravity difference with the gas, centrifugal type air using an electric motor A purifying apparatus, comprising: to clean air with high performance based on the principle of fluid flow that generates centrifugal force by using a centrifugal impeller that rotates bacteria, dust, fine particles and other contaminants contained in the air at high speed by an electric motor. It is made up.

On the other hand, the clean air lightened by centrifuging the contaminated water is discharged to a predetermined clean air place through the exhaust pipe 832 through a plurality of exhaust holes 850 formed in the exhaust cylinder or the vortex cylinder 813.

3, as shown in the operation diagram of FIG. 1, it is possible to configure and use the washing tub 801 in the lower portion of the inverted body (807). As the centrifugal impeller 808 attached to the rotating shaft 835 of the electric motor 833 rotates, negative pressure due to air flow is generated in the venturi nozzle 803A provided in the intake pipe 831. Therefore, the water in the washing tub 801 is sucked through the venturi tube 802A and sprays or atomizes the fine moisture particles in the form of fog. On the other hand, the air is sucked from the outside through the intake port 805, and the contaminants in the air pass through the intake pipe 831 and are collected three-dimensionally based on the viscous adsorption force of water by the fine moisture particles in the form of fog.

Thus, as the centrifugal impeller 808 having a three-dimensional hydrodynamic structure generating air attraction and centrifugal force rotates, as shown by the arrow, air is attracted in the axial direction and generates centrifugal force in the circumferential direction. In this case, when the flow guide 808A is attached to the centrifugal impeller 808 as a cap, the inflow air flows between the conventional shroud fixed surface and the rotating centrifugal impeller, thereby preventing pressure loss. Separation effect can be improved, and further, by converting a wing shape having a backward tilt angle at the distal end portion of the centrifugal impeller 808 into a shape perpendicular to the circumferential surface, the centrifugal effect can be further improved. In the present invention, an improved centrifugal impeller combining the flow guide 808A with the centrifugal impeller 808 may be used to improve the centrifugal effect as described above.

Here, the axial fan 808E is installed at the upper end of the multi-rotor sirocco fan 808C to effectively suck air, reinforce structural strength to withstand high speed rotation, and strongly fix it to the rotating shaft 835 shown in FIG. 1. have. Therefore, even if a low-speed rotation motor is installed on the basis of the multi-rotor sirocco fan 808C provided in the main body 807, as in the function of the high-speed rotating centrifugal impeller, a large amount of air can be sucked and a centrifugal separation effect can be expected. The multi-rotor sirocco fan 808C is preferably configured in the form of a streamlined cone such as a Francis type impeller so that air intake and centrifugation can occur efficiently. The Francis type impeller is a well-known technical concept in hydraulics, and thus a detailed description thereof will be omitted.
