In order to effectively remove dust using water, it is necessary to set the ratio of water and dust to a similar ratio, approximately 1:1, and for this purpose, water must be crushed and mixed with dust. However, the surface area of the dust should not be larger than the surface area of the water particles, and in the process of spraying water or in the process of meeting water and dust, the water must be smashed to create an environment where dust and water particles can be in maximum contact.

The present invention can optimize the structure of the blower pipe 200, which is a space in which dust and water particles are in contact, thereby maximizing the combination of dust and water particles.

An air purifying apparatus using water spray according to an embodiment of the present invention includes a blowing fan 100 for sucking air; The blower pipe 200 is provided on the inner surface of the blower pipe 200 and the blower pipe 200 configured to pass air sucked by the blower fan 100, and has a plurality of spray nozzles 410 spraying water to blow the blower pipe 200. It includes a sprinkling pipe 400 for spraying water so that the passed air and the sprayed water particles meet.

Can.

In particular, referring to FIG. 2, the blower pipe 200 includes water particles together with a suction region 210 for receiving air sucked by the blower fan 100, a passing region 220 in which the watering pipe 400 is mounted, and air. It is divided into the discharge area 230 for discharging the, and the cross-section of the passage area 220 is set smaller than the cross-section of the suction area 210 and the discharge area 230 to have a venturi tube shape.

The Venturi tube means a special tube made of a constricted part in the tube, and the air velocity in the constricted part of the Venturi tube, that is, the passage region 220 is increased. For example, the venturi tube may be designed such that the actual air flow rate in the passage region 220 is 30 to 100 m/s or specifically 60 to 70 m/s.

The venturi tube-type blower pipe 200 moves air and dust at a high speed, and in particular, the speed in the passage region 220 where the dust and water particles meet can be faster, so that the water particles can be split into smaller pieces like fog. Through this, the combination of dust and water particles can be maximized. In more detail, in the venturi tube-type blower tube 200, the passage region 220 has a relatively small space and thus has a high density, and since the gap between water particles is small, the probability of dust and water particles meeting may be greater. .

Air purification apparatus using water spray according to an embodiment of the present invention is located on the movement path of the water particles discharged together with the air passing through the blower pipe 200 and the first mesh 510 to control the scattering of water particles ; A storage tank 300 for storing water particles that have passed through the first mesh 510; A second mesh 520 may be provided on the reservoir 300 to control scattering of the stored water.

In addition, the first mesh 510 may be located on a moving path of dust and water discharged from the discharge area 230 of the blower pipe 200 to control scattering or re-aggregation of water particles, through which water particles are ducted. It can be prevented from escaping through 600. In addition, since the air velocity of the air passing through the venturi pipe-type blower pipe is fast, the dust and water are lowered by the straight air flow, and in the process, contact the surface of the first mesh.

In one embodiment, the shape of the first mesh 510 may be provided in a shape corresponding to the shape of any one of the cross-sections of the discharge area of the blower pipe.

In one embodiment, the second mesh 520 is preferably larger than the maximum cross-sectional size of the cross-section of the discharge area of the blower pipe. That is, it is preferable that the diameter of the second mesh is larger than the maximum diameter of the discharge area of the blower pipe. In this case, water mixed with dust passing through the first mesh may fall into the reservoir while passing through the second mesh, and droplets splashing while falling into the reservoir may meet the second mesh.

Dust and water that have passed through the first mesh 510 are collected in the reservoir 300, and the second mesh 520 is positioned on the reservoir 300 to control scattering of the stored water. In detail, as the dust and water passing through the first mesh 510 fall to the water storage tank 300, water droplets may drip, but in the second mesh 520, the water droplets mixed with the splashing dust are returned to the water storage tank 300. It can function to be stored. For example, the first mesh 510 and the second mesh 520 may use a filter mesh of 2 mesh to 20 mesh, and specifically, a filter mesh of 12 mesh. Also, the first mesh 510 and the second mesh 520 may be designed to have different densities.

The air purifying apparatus using water spray according to an embodiment of the present invention includes a first mesh 510 and a second mesh 520 to effectively discharge or circulate air from which dust has been removed by water into the duct 600. Can.

The plurality of spray nozzles may be provided in the direction of the central axis of the blower pipe from the outer surface of the inner ring structure of the sprinkler pipe, and each spray nozzle is spaced at a predetermined interval so that the air containing the sprayed water particles and dust can be efficiently mixed. It may be provided with.

That is, the water spray pipe 400 can increase the density of water particles in the passage region 220 of the blow pipe 200 by spraying water in the direction of the central axis of the blow pipe 200, through which the passage region 220 It is possible to maximize the contact between air and water particles including dust passing therethrough.

For example, the sprinkling pipe 400 may have a ring shape corresponding to the shape of the blower pipe 200 and spray water in the direction of the central axis of the blower pipe 200. The ring may have a circular ring, a square ring, or a polygonal ring shape, and is not limited as long as it is a ring shape having a shape corresponding to a shape of a blower pipe.

In addition, a plurality of sprinkling pipes 400 may be mounted along the inner surface of the blower pipe 200. Due to this structure in which two or more sprinkler pipes are mounted, the blower pipe 200 may form a tunnel-like structure through which air and water particles pass. Dust can be effectively combined with water particles as air including dust passes through the passage region 220 while water is sufficiently sprayed inside the blower tube 200 formed in a tunnel-like structure.
