As a result, the water supplied from the pump 104 injects water into the air passing through the diffuser unit 120 through the plurality of nozzles 128, thereby removing dust and droplets contained in the air passing through the diffuser unit 120. The same foreign matter is adsorbed on the water to separate dust or droplets.

In addition, by providing a plurality of nozzles 128 in the inlet 122 and the outlet 126, respectively, the water is first injected through the plurality of nozzles 128 provided in the inlet 122 and the outlet 126. By secondary injection through a plurality of nozzles 128 provided in the), it is possible to more effectively perform the separation by dust and droplets of water.

As a result, the removal of the foreign matter including the dust and droplets is not only dependent on the filter to be described later, but the dust and droplets can be naturally separated using water sprayed through the plurality of nozzles 128 in the diffuser 120. By doing so, it is possible to extend the life of the filter and to reduce the filter replacement cost.

Thus, the dust and droplets separated by the water sprayed from the nozzle 128 in the diffuser portion 120 flows into the tank 110 through the discharge portion 126 and is then filled in the bottom of the tank 110. Accumulated in the water and through the entrance 108, the worker can enter the inside of the tank to remove the foreign matter accumulated on the floor through the cleaning operation.

"The shape of the joint member 134 is inserted to maintain the spacing interval, and each plate 132 is coupled to the joint member 134 by using bolts and nuts.

On the other hand, the plurality of plates 132 is formed so that a plurality of through-holes 136 are formed at a predetermined interval so that air introduced into the tank through the diffuser portion 120 passes through the plurality of through-holes 136. At this time, the size of the plurality of through-holes 136 is formed in a constant size so that only the size of 10μm or less of the dust contained in the air can pass through.

That is, the air mixed with the water sprayed through the nozzle 128 while passing through the diffuser unit 120 includes moisture as well as foreign substances such as dust and droplets, which is the plate 132 of the primary filter 130. ) And the collision occurs to remove moisture contained in the air, and passes through a plurality of through holes 136 formed in the plate 132, the coarse and large dust and droplets of more than 10μm contained in the air is filtered out, the filtered dust and liquid The enemy flows downward along the plate 132 by its own weight and collects into the water stored at the bottom of the tank.

Meanwhile, the plurality of through holes 136 formed in the plate 132 are formed to cross each other with the plurality of through holes 136 formed in the neighboring plate 132, so that the adjacent plates 132 spaced apart at regular intervals. Air passing through) does not pass in a straight line, and the air passing through the first placed plate 132 collides again with the second placed plate 132, and then the through hole formed at a position away from the straight line 136 Will pass).

This causes the air passing through the primary filter 130 to pass through the through holes 136 formed at different positions in a zigzag, thereby not only lengthening the air passage but also causing collisions several times in the primary filter 130. It is possible to more effectively separate and remove the dust and droplets contained in the air.

It is dispersed in the left and right directions by) and flows into the secondary filter 140. The air introduced into the secondary filter 140 moves along the first slope 143 to separate moisture by its own weight.

In addition, the air moving along the first inclined surface 143 impinges on the first bent portion 144 formed at the end of the first inclined surface 143 and is rotated to move along the first inclined surface 143. The air that is rotated after colliding with the first bent portion 144 generates a vortex, and the air collides with each other by such vortices, thereby removing a part of the dust and droplets and a large amount of moisture that are not removed from the primary filter 130. This separation flows downward along the first inclined surface 143 and accumulates in the water stored in the tank.

Meanwhile, air from which dust, droplets, and water are separated and removed from the first inclined surface 143 and the first bent portion 144 passes through the first moving path 147 and is spaced apart from the first inclined surface 143 by a predetermined interval. It collides again with the second inclined surface 145 located at. After the dust, droplets, and water are separated and removed again by such a collision, they move along the second slope 145 and collide again with the second bent portion 146 formed at the end of the second slope 145.

It is separated and flows downward along the second inclined surface 145 to be accumulated in the water stored in the tank.

As such, the secondary filter 140 extends the air flow path by the first and second bent parts 144 and 146 formed at the ends of the first and second bevel surfaces 143 and 145 and the first and second bevel surfaces 143 and 145 that are bent. It is possible to maximize the efficiency and effect of the separation and removal of dust, droplets and moisture contained in the air.

Down to the bottom.

The air, which has been hit twice, moves along the third inclined surface 157 and is separated and removed again by a collision generated by the collision caused by the third bent portion 159 formed on the rear surface of the bent plate 153. Vortex is formed by the air colliding in the unit 159 and the air moving along the third inclined surface 157. Due to the vortex, the air collides again, and the dust is separated and removed, and then collides with the bent plate 153 which is spaced apart at a predetermined interval and disposed behind. The air passing through the bending plate 153 disposed in the front is separated and removed from the dust contained in the air by the same action generated in the above-described bending plate 153 disposed in the bending plate 153 disposed in the rear. As a result, the dust contained in the air can be separated and removed more effectively.

Meanwhile, a drain pipe (not shown) may be further formed on the lower surface of the tertiary filter 150 between the third slope 157 and the neighboring third slope 157. This is because the air introduced into the tertiary filter 150 collides with the bending plate 153 disposed in the front and rear, and the dust separated and removed from the air flows downward along the bending plate 153, and flows downward. The dust is discharged to the outside of the tertiary filter frame 151 through the drain pipe (not shown) to move to the water stored in the tank.
