The central part of the washing chamber 10 has a rotary shaft 30, supported by a bearing and a bearing housing 32 at both ends of the rotary shaft 30, one end of the rotary shaft 30 is a motor 21 and a power transmission device ( 22 is connected to and interlocked with the necessary power is transmitted, the other end of the rotary shaft 30 is configured with a blowing wing (20). The inner wall of the washing chamber 10 has a plurality of fixing pins which are maintained toward the center of the washing chamber from the inner wall of the washing chamber while maintaining a constant interval on a circumferential line on any one cross-section of the inner wall behind the blower blade 20 ( 15), the fixing pin 15 is formed a plurality of spaced apart at a constant distance in the rear longitudinal direction of the inner wall of the washing chamber (10).

In addition, the washing chamber 10 is provided on the inner center line in the longitudinal direction and is installed on the surface of the rotary shaft 30 and the rotary shaft 30 is installed so as not to contact the end of the fixing pin 15, the washing chamber (10) while maintaining a certain interval on the cross-sectional line of the surface of the rotary shaft 30 corresponding to the intermediate position between the fixing pin 15 and the fixing pin 15, which is built on a plurality of cross-sectional lines of the inner wall, Rotating pins 31 which do not collide with the fixing pin 15 and do not contact the inner wall of the washing chamber 10 and rotate at high speed together with the rotating shaft are formed. The length should be designed to minimize leakage of contaminated air into a gap that does not reach the pin while ensuring smooth rotation of the rotating shaft 30 and the rotating pin 31.

One side of the washing chamber 10 is provided with an inlet 11 for sucking contaminated air, and the exhaust port 12 and the exhaust guide tube 13 and the water mixing prevention wing for discharging the purified air on the other side There is 16

Meanwhile, referring to FIGS. 3 to 4, the outlet 12 of the purified air may be formed in a form different from that described above, that is, from the upper space of the washing water storage tank, Purified air to the outside through the exhaust guide pipe 13-1 protruding from the lower part in the washing chamber 10 through the lower part and the exhaust port 12-1 provided in the upper wall of the washing water storage tank. Can be discharged.

A spray nozzle 43 for spraying the washing water into the contaminated air at one end of the air suction side of the washing chamber 10 is provided in front of the blower vane 20, and the spray nozzle 43 is pressurized with the washing water supply pipe 40. It is connected to the wash water storage tank 50 through the pump 42 and the water filter 41. The storage tank 50 includes an automatic water supply valve 51, a drain valve 52, and a chemical inlet 53.

In the lower part of the washing chamber 10, the dirty contaminants in the air are washed and separated from the air, the washing water collected and collected through the drain 14 to the washing water storage tank 50 is circulated in the air purification and used repeatedly.

In addition, the spray nozzle 43 of the washing water supply means, pressurized pump 42, when used to separate / recover the water and chemicals of the wet air mixed with a large amount of water and chemical particles generated in the industrial washing process, etc. The water filter 41 and the washing water supply pipe 40 and the automatic water supply valve 51 of the washing water storage tank 50 may be omitted or not used.

Hereinafter, the operation and operation of one embodiment according to the present invention described above will be described in detail.

1, 2, 3 to 4, first to supply the water to the appropriate level through the automatic water supply valve 51 to the washing water storage tank 50 in the lower portion of the water cleaning air purifier, When the watch is turned on to supply power, the motor 21 or the power transmission device 22 operates to transmit power to the rotating shaft, and the rotating shaft 30 rotates at a high speed, and the air contaminated by the suction force generated by the blower blade 20. The suction is introduced into the suction port 11 of the washing chamber 10, and the washing water is sprayed and mixed into the contaminated air in a small particle state by the pressure pump 52 and the spray nozzle 43. The contaminated air mixed with a large amount of water collides with the pins numerous times and is beaten while passing through the passage formed with the pair of fixed pins 15 and the rotating pins 31 rotating at high speed in the washing chamber 10. Like tapping a laundry with a laundry bat, it is similar to sucking a laundry by hand, and the polluted air is split very finely into contact with water, and the contact area is enormously enlarged, so that fine dust and pollutants in the air It is cleaned / removed cleanly.

For reference, when calculated by the values exemplified below, when the contaminated air passes through the rotary pin 31 and the fixing pin 15, the degree of collision with the pins and the degree of finely splitting and dividing can be roughly known.

Cylindrical diameter of washing chamber: 300mm Rotational speed: 1800 rpm

Number of pins in a row: 12, Number of pins in pin: 7

Number of rotating pins in a row: 6 Number of rotating pins: 6

Diameter of the pin: 10mm

Axial distance between fixing pin and fixing pin of next stage: 20mm

If the polluted air speed is 6000mm / sec,

Pin tip speed V = 300 x 3.14 x (1800 ÷ 60) = 28260mm / sec

Rotating Pin Axial Speed V '= 80 x 3.14 x (1800 ÷ 60) = 7536mm / sec

The distance between the push pin and the push pin s is s = 300 x 3.14 ÷ 12 = 78.5 mm (in the inner wall of the passage), 20.9 mm (in the center of the passage), and the time it takes for the rotary pin to reach the next pin (t) '= s ÷ V = 78.5 ÷ 28260 = 0.0028 seconds, the distance s "in the axial direction between the fixed pin and the next fixed pin is 20mm, and the time taken for contaminated air to pass through this distance t" = 20 ÷ 6000 = 0.0033 seconds.

Here, while the contaminated air travels 20mm between the fixed pin and the next fixed pin, the rotary pin has a distance of 78.5mm between the fixing pin (at the end of the pin) and 20.9mm (with a diameter of 80). The air flows through the air at a speed of 28260mm / sec and 7536mm / sec. In other words, the distance that the rolling pin goes at 0.0033 seconds is 28260mm / sec x 0.0033 = 93.3mm, 7536mm / sec x 0.0033 = 24.9mm, which runs more than the distance between the circumferential fixing pins of the same cross section. Occurs repeatedly on the stationary and rotating pins.

In this process described above, the sprayed water is mixed with the fixed pin rotary pin and the fixed pin rotary pin .... in order to collide violently in succession, and enormous vortices occur in the air flow, Severe friction and collisions occur between pollutant particles, and the contact surface between water and air is infinitely large, and contaminants in the air are cleaned and removed by water.

Here, if the number and number of the fixing pins 15 and the rotating pins 31, the thickness of the pins, the distance between the fixing pins and the rotating pins, the shape of the pins, and the number of rotations of the shaft are more appropriately changed, the existing air purifier can be hardly realized. The removal of very small dust particles and gaseous contaminants, as well as air disinfection, is sufficient.

The sprayed water receives a large centrifugal force while colliding with the rotary pin 31 while the mixed air passes through the fixed pin 15 and the rotary pin 31, and reaches the final rotary pin 31 of the rotary pin 31. Is separated from the air and gathers toward the inner wall of the washing chamber, and is recovered to the washing water storage tank through the drain hole 14 in the lower portion of the washing chamber 10 and circulated again to use to clean the polluted air.

When the dirty contaminants are removed and separated from the water, the purified air is discharged to the outside through the exhaust guide tube 13 and the exhaust port 12 which protrude in the inner longitudinal direction of the washing chamber 10. The water mixing prevention blade 16 of 13) prevents the water collected into the inner wall of the passage from being mixed with the air discharged again.

On the other hand, referring to Figures 3 to 4, the method of exhausting the purified air is not limited only to the above technique, the washing chamber (through the lower portion of the washing chamber 10 from the upper space of the washing water storage tank 50) 10) to the outside through the exhaust port (12-1) provided on the upper outer wall of the wash water storage tank through the exhaust guide pipe 13-1 and the upper space of the wash water storage tank protruding into the lower portion of the inside. When discharged, the flow rate is drastically reduced as the air flow changes rapidly from the vertical down direction to the vertical upward direction, so even if there are water particles entrained in the air, it is separated from the air again by inertia force and water is not mixed with the discharged air.

The water naturally consumed by the operation of the air purifier is automatically replenished by the automatic water supply supplement valve 51 and always maintains a constant water level. The dirty water used for a certain period of time is discharged using the drain valve 52. Replace with clean water.

The water filter 41 of the washing water supply pipe prevents the spray nozzle 43 from being clogged by foreign matter so that the washing water is always smoothly sprayed, and the periodic water filter 41 needs to be cleaned.

In addition, the spray nozzle 43 of the washing water supply means, pressurized pump 42, when used to separate and recover the water and chemicals of the wet air mixed with a large amount of water and chemical particles generated in the industrial washing process, etc. If the water filter 41 and the washing water supply pipe 40 are omitted or not used, and the separated and collected water reaches a predetermined level without using the automatic water supply valve 51 of the washing water storage tank 50, the drainage device Drain through (52).

Water purifier air purifier according to the present invention, by tapping the polluted air sprayed with water in the washing chamber numerous times, very finely split and divided, and the contact surface with the water is almost infinitely large to clean / remove, The removal of extremely small fine dust and a large amount of dust powder, which was almost impossible, can be effectively removed with a minimum static pressure loss, thereby reducing the size of the air purifier and improving the quality of the air purifier.

In addition, the water cleaning air purifier according to the present invention has no phenomenon that the air filter generated in the filtration type air purifier is not clogged at all, so that the static pressure loss does not occur, the blowing efficiency is high, and the filter replacement and cleaning are not necessary at all. It is very easy to manage and exchange cost is very low.
