Fig. 4 is a view schematically showing a state in which a male attaching portion is added in Fig. 1. Fig. Referring to FIGS. 1 to 4, the scrubber 1 according to an embodiment of the present invention may further include a water receiving portion 50. The water adhering portion 50 is embedded in the case portion 10 and is disposed between the water discharging portion 20 and the handmade refuse 30 to adhere moisture in the exhaust gas.

The attachment protrusions 51 of the water attachment portion 50 are alternately protruded from both sides of the inside of the cylindrical portion 11 of the case portion 10 to guide the exhaust gas to move in a zigzag manner. For example, the attachment protrusions 51 may be formed to have an isosceles triangle shape in cross section so that the upper side and the lower side have an inclination. This allows the water to flow down along the upper and lower sides after moisture is deposited.

The water-attaching portion 50 may further include an attachment cooling portion 52. The attachment cooling section 52 is mounted on the attachment projection section 51, and cools the attachment projection section 51. When the attachment protrusions 51 are cooled, the condensed water adheres to the attachment protrusions 51 to improve the water recovery rate. For example, the attachment cooling section 52 can cool the attachment projection section 51 while the cooling water is circulated.

The operation of the scrubber according to one embodiment of the present invention will now be described.

The exhaust gas flowing into the lower portion of the cylindrical portion 11 is purified while passing through the water discharging portion 20, the water attaching portion 50, the handmade refuse 30, and the water receiving portion 40 in sequence, .

The water discharging portion 20 injects water so that moisture is adsorbed by the exhaust gas. At this time, the water discharging portion 20 can spray water in a spray form so as to improve the attraction force of water and exhaust gas.

The attachment protrusions 51 guide the exhaust gas containing moisture in a staggered manner. As a result, a part of the moisture of the exhaust gas adheres to the attachment protrusions 51 together with the harmful substances and flows down. At this time, if the attachment protrusions 51 are cooled by the attachment cooling section 52, the water adhesion rate on the surface of the attachment protrusions 51 can be improved.

The exhaust gas that has passed through the water adhering portion 50 passes through the first handmade rejection 31 and the second homemade rejection 32 in order and finally passes through the male membrane portion 40. At this time, a first water treatment section 33 is arranged between the first handmade refuse 31 and the second handmade refuse 32, and a second water treatment section 33 is disposed between the second handmade refuse 32 and the water receiving section 40 34 are disposed.

When the water filtered by the first handmade refuse 31 accumulates, the water drops into the water adhering portion 50. When the water filtered by the second handmade refuse 32 is accumulated, the water is collected through the first water treatment portion 33 into the cylindrical portion 11, So that it does not affect the first handmade rejection 31. When the water filtered by the water receiving portion 40 is accumulated, the water drops to the inside of the cylindrical portion 11 through the second water processing portion 34, and does not affect the second homemade rejection 32. That is, the falling water is bypassed by the first water treatment section 33 and the second water treatment section 34 to the first homemade rejection 31 and the second removal section 32. As a result, it is possible to prevent the exhaust gas passing rate from decreasing due to excessive moisture of the first homemade refuse 31 and the second homemade refuse 32.

The first inclined projection 333 has a shape converging toward the upper portion and a first inclined hole portion 332 is formed at the highest point of the first inclined projection 333. [ The first inclined hole portion 332 is formed uniformly over the entire surface of the first inclined plate portion 331. As a result, the exhaust gas is increased in speed while passing through the first inclined hole portion 332, and is evenly supplied over the entire surface of the second homemade refuse 32.

Likewise, the second inclined projection 343 has a shape converging toward the upper portion, and the second inclined hole portion 342 is formed at the highest point of the second inclined projection 343. The second inclined hole portion 342 is formed uniformly over the entire surface of the second inclined plate portion 341. As a result, the exhaust gas is increased in speed while passing through the second inclined hole portion 342, and is uniformly supplied over the entire surface of the water receiving portion 40.

In the scrubber 1 according to an embodiment of the present invention, the first homemade refuse 31 and the second homemade refuse 32 are arranged in the upper and lower directions to remove moisture, thereby improving the purification efficiency of the exhaust gas.

The scrubber 1 according to the embodiment of the present invention is configured such that the first water processor 33 disposed between the first handmade refuse 31 and the second handmade refuse 32 is dropped from the second handmade refuse 32 It is possible to suppress the lowering of the exhaust gas passing rate of the first homemade reject 31 due to the water falling in the second homemade reject 32 because the water is treated.

The scrubber 1 according to an embodiment of the present invention is configured such that the second water treatment portion 34 disposed between the second hand rest 32 and the water receiving portion 40 processes moisture falling from the water receiving portion 40 , It is possible to suppress a decrease in the exhaust gas passing rate of the second homemade refuse (32) due to the water falling from the water receiving portion (40).

The scrubber 1 according to an embodiment of the present invention can arrange the cooled water attaching portion 50 between the water discharge portion 20 and the handmade refuse 30 to pretreat water.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand. Accordingly, the true scope of protection of the present invention should be defined by the following claims.
