In addition, the scrubber 120 is connected to one side of the water storage tank 110 .

Thus, the first fluid introduced into the water storage tank 110 through the first inlet 112 passes through the scrubber 120 and is exhausted. At this time, the first fluid separates and falls part of the harmful substances into the second fluid stored in the water storage tank 110 .

In addition, since the first fluid has a lower specific gravity than the second fluid, the scrubber 120 is connected to the upper surface of the water storage tank 110 .

In addition, the water storage tank 110 forms an outlet 116 to allow the introduced first fluid to flow toward the scrubber 120 . The scrubber 120 has a substantially cylindrical shape, is formed to be opened to both sides along the axial direction, and is fixedly installed on the upper surface of the water storage tank 110 along the edge of the outlet 116 .

In particular, the process water supply line 220 includes a supply pump 224 . Thus, the supply pump 224 forces the second fluid of the water storage tank 110 to flow along the process water supply line 220 at a set flow pressure.

In addition, the process water supply line 220 located inside the scrubber 120 is provided with a spray nozzle 222 at the end. At this time, one or more injection nozzles 222 are provided, and direct injection of the second fluid toward the frame 210 or injection guidance into the internal space of the scrubber 120 corresponding to the upper portion of the frame 210 is provided.

At this time, the flow guide hole 232 is formed to be opened in the same circumferential direction on a plane inside the frame 210 .

Thus, the first fluid changes the flow direction or guides the diffusion flow while passing through each flow guide hole 232 . At this time, the flow rate of the first fluid is determined by the discharge fan (122).

In addition, the flow guide hole 232 of the guide vane 230 serves to discharge the falling second fluid while collecting harmful substances from the upper portion of the frame 210 in the internal space of the scrubber 120 .

In more detail, the frame 210 constitutes an edge with a first surface 215 , a second surface 216 , a third surface 217 , and a fourth surface 218 along the circumferential surface according to the quadrangular frame shape. .

Thereafter, the turbulent first fluid strikes the second fluid sprayed from the inside of the scrubber 120 to the upper portion of the frame 210 .

Due to this, the second fluid is atomized and the specific volume is increased. Thus, harmful substances and foreign substances in the first fluid are aggregated in the atomized fluid.

As the harmful substances and foreign substances are aggregated in the second fluid, the second fluid is bubbled. Therefore, the aggregation efficiency of harmful substances and foreign substances contained in the first fluid is increased.

In addition, the second fluid, which aggregates harmful substances and foreign substances, falls to the surface of the guide vane 230 by its own weight. Thereafter, due to the inclined arrangement of the guide vanes 230 , the second fluid falls into the water storage tank 110 through the flow guide hole 232 .

Accordingly, the second fluid in which harmful substances and foreign substances are aggregated is prevented from being deposited on the guide vanes 230 . In particular, as the first fluid flows in a turbulent flow, the second fluid in which harmful substances and foreign substances are aggregated is forcibly slid and dropped from the surface of the guide vane 230 .

In addition, the first fluid exhausted to the upper portion of the scrubber 120 contains water. Therefore, the scrubber 120 may include a demister 124 to aggregate and separate and discharge the water of the first fluid.
