In other words, due to the operation of the suction fan 130, the water and air rapidly flowing into the fluid rotating cyclone 150 are spirally moved due to the shape of the fluid rotating cyclone 150 and then discharged to the inner space part 1211. , The discharged water and air are rapidly moving and rising along the inner circumferential surface of the inner space portion 1211 of the main body 120.

However, the discharged water moves in a spiral shape along the inner circumferential surface of the inner space portion 1211, and then moves over a certain distance and then falls by gravity.

At this time, the pollutants contained in the water also fall with the water.

In summary, the shape of the fluid rotating cyclone 150 is a shape that rises while drawing a spiral, and the upper end of the fluid rotating cyclone 150 is disposed to be close to the inner circumferential surface of the inner space portion 1211 of the main body 120, The rapidly discharged water and air move spirally along the inner circumference of the inner space part 1211 and rise, and the discharged water and air cause vortices in the inner space part 1211 to rise.

The water discharged to the internal space portion 1211 at a high speed due to the vortex phenomenon falls after moving a certain distance, but may continue to rise with air in some cases.

However, in the present invention, after the water hits the blocking plate 160, the rapidly decelerated water falls downward by gravity, so that most of the water containing contaminants can be easily moved to the reservoir 110. There will be.

Therefore, the blocking plate 160 is installed at a right angle to the discharge direction of the water and air discharged through the upper end of the fluid rotating cyclone 150, and at the same time, an area larger than the cross-sectional area of the internal passage 151 of the fluid rotating cyclone 150. It is preferably made to have a shape to effectively reduce the flow rate.

Mist drop plate 180,

2 and 3,

It is installed along the inner circumference of the inner space portion 1211 of the main body 120 located on the upper side of the fluid rotating cyclone 150,

It consists of a belt shape having a downward inclined surface, and after passing through the fluid rotating cyclone 150, the water that has risen while vortexing is blocked to fall and induce the air to continue to rise.

As mentioned above, most of the water discharged through the fluid rotating cyclone 150 moves in a spiral along a circumference of the inner circumferential surface of the inner space portion 1211, and then rises and falls, but in some cases strong vortex phenomenon. Due to this, a part of the water may not fall and may continue to rise spirally along the inner circumference of the inner space portion 1211 of the body 120 together with air.

However, the water rising along the circumference of the inner circumferential surface of the inner space portion 1211 hits the downward inclined surface of the mist falling plate 180 and is decelerated and then falls.

That is, most of the water discharged through the fluid rotating cyclone 150 rises and then falls by gravity, and a portion of the water that continues to rise is hit by the mist falling plate 180 and is decelerated before falling.

Stainless steel filter 190,

2 and 3,

It is installed in the inner space portion 1211 of the main body 120 located on the upper side of the mist drop plate 180, and is configured to block water and drop it and pass air through it to the outlet.

The stainless mesh filter 190, the perforated plate 191, the edge of which is placed along the upper surface of the stepped portion 1217, the filter body 192, which is placed on the upper portion of the perforated plate 191, the filter It is made of a pressing perforated plate (193) mounted on the upper portion of the body (192),

The stepped portion 1217, the perforated perforated plate 191, the filter body 192, the pressing perforated plate 193 is configured to be bolted to each other.

Most of the water hitting the mist drop plate 180 is decelerated and falls, but in some cases, due to a strong vortex phenomenon, only a small portion of the water that has not been dropped may rise along the flow of air. 190) can effectively block the rise of water.

In the present invention made of the above configuration, to summarize the movement path of water and air, respectively,

Figure 4 shows the movement path of the water,

When the suction fan 130 is operated, water flows into the dust collection induction duct 140, and water is formed between the lower part of the dust collection induction duct 140 and the water surface by the orifice principle, and a water film is formed. The contaminated air introduced into the accommodating portion 111 of the 110 is mixed with water while passing through the rising water film.

Therefore, the water containing contaminants passes through the dust collection induction duct 140 and flows into the fluid rotating cyclone 150 through the communication hole 114.

And the water passing through the fluid rotating cyclone 150 is rotated and discharged in a spiral due to the shape of the fluid rotating cyclone 150, thereby causing vortex phenomena in the inner space portion 1211 of the main body 120 to move, and blocking A portion of the water hitting the plate 160 drops by decelerating, and the rest of the water rises while moving a certain distance due to a vortex phenomenon and then falls naturally by gravity.

And some of the water that continued to rise without falling falls on the mist dropping plate 180 and then decelerates and falls, and even after striking the mist dropping plate 180 due to strong vortex phenomenon, the water that has not risen without falling is the stainless steel. After hitting the mesh filter 190, it falls and flows into the water storage tank 110.

Therefore, the contaminants are included through the above process, the water flowing into the internal space portion 1211 falls and flows into the reservoir 110, and the purified air from which contaminants have been removed is discharged through the exhaust port 1221. Will be.

Figure 5 shows the path of movement of air,

When the suction fan 130 is operated, a water film is formed between the lower part of the dust collecting induction duct 140 and the water surface by an orifice principle, and at this time, it is introduced into the receiving part 111 of the water storage tank 110. As the contaminated air passes through the rising water film and comes into contact with water, contaminants contained in the air are mixed with water and rises in the inner space portion 1211 of the main body 120 and then falls with water as mentioned above.

At this time, the purified air that does not contain contaminants is decelerated briefly after hitting the blocking plate 160 immediately after being discharged from the fluid rotating cyclone 150, but continues to rise along the circumference of the inner circumferential surface of the inner space portion 1211 by the vortex phenomenon. do.

And the purified air that has risen is decelerated briefly after hitting the mist drop plate 180, but continues to rise along the inner circumference of the inner space portion 1211 beyond the mist drop plate 180 due to a vortex phenomenon.

In addition, the purified air is discharged through the exhaust port 1221 after passing through the stainless mesh filter 190.

Therefore, in the present invention, the contaminants contained in the air are mixed with water and rapidly discharged to the inner space portion 1211 of the main body 120, and then naturally discharged by gravity or collided with the blocking plate 160 to slow down. It is mostly filtered primarily by falling.

In addition, the contaminant bill, which failed to fall and rose with water due to a vortex phenomenon, is secondaryly filtered by falling by physical collision with the mist falling plate 180.

In addition, in some cases, contaminants that have been continuously mixed with water beyond the mist drop plate 180 are filtered thirdly by hitting the stainless steel filter 190 and then falling.

Therefore, the present invention can improve the filtration efficiency for contaminated air.
