1 to 4, the present invention is a scrubber (200, scrubber) that mainly adsorbs SOx in the center, and the exhaust gas flowing from the upper side descends along the spiral path to the exhaust gas. It can be understood that the structure includes the first unit 100 provided as a cylindrical space so that the contained PM is adsorbed.

The first unit 100 includes a first body 110 in which a space is formed, and an exhaust gas inlet part formed on an upper side of the first body 110 and into which exhaust gas containing PM and SOx flows in ( 120) and a cleaning liquid discharge unit 130 formed at a lower end of the first main body 110 to discharge cleaning liquid used for purification of exhaust gas.

The exhaust gas inlet 120 may be formed on an upper side of the first body 110 in a direction parallel to the tangential direction of the wall of the first body 110. The exhaust gas flowing through the exhaust gas inlet 120 flows in a downward direction while turning along the inner wall of the first body 110 by flowing parallel to the tangential direction of the first body 110.

The PM contained in the exhaust gas that descends through the spaced apart space between the first body 110 and the scrubber 200 has a sufficient centrifugal force and is applied to the inner wall of the first body 110 or the outer wall of the scrubber 200. It falls by inertial collision.

At this time, a guide vane 160 (guide vane) may be installed inside the first body 110 to guide the exhaust gas descending orbiting along the spiral path.

The guide vane 160 is formed between the inner wall of the first body 110 and the outer wall of the scrubber 200, and the exhaust gas flowing from the exhaust gas inlet 120 together with the cleaning liquid is the bottom of the first body 110 It forms a spiral path toward the surface and serves to guide it to move.

The guide vane 160 not only serves to guide the flow of the exhaust gas that rotates and descends inside the first body 110, but also forcibly delays the flow of the exhaust gas along a path in a spiral direction, thereby contacting the gas-liquid of the exhaust gas and the cleaning liquid It can be said to be a technical means provided to increase the adsorption rate of PM contained in exhaust gas by increasing the opportunity.

On the other hand, the present applicant is located near the bottom surface of the first body 110 from the exhaust gas inlet 120 is formed on the upper side of the first vane 160, as shown in Figure 2 When it is configured in a form extended to the longest, it has been found that a problem arises in that a turbulence occurs and rather, the flow of the exhaust gas orbits and descends.

In order to solve this problem, the present applicant provides a shorter guide vane 160 as shown in FIG. 3 to be installed only on the inlet side of the first body 110, that is, on the exhaust gas inlet 120 side, Alternatively, as shown in FIG. 4, a configuration in which a shortly formed guide vane 160 is installed on the inlet side of the first body 110 and the intermediate layer of the first body 110 is designed.

That is, the number of guide vanes 160 installed inside the first body 110 along the length of the first body 110 can be flexibly adjusted. However, even in this case, the guide vanes 160 that are installed in plural are provided independently of each other, and it is preferable that they are installed to be separated from each other by a predetermined distance or more.

In the embodiment shown in FIGS. 3 and 4, the meaning that the guide vane 160 is'shortly formed' may mean that the guide vane 160 is formed by rotating in a range of 0.5 to 1.5 wheels. , More preferably, the guide vane 160 is preferably formed by rotating about 1 turn.

Referring back to FIG. 1, the first unit 110 may further include first and second spray assemblies 140 and 150 installed inside the first body 110.

In addition, the drying unit 230 according to the present invention is a member that removes moisture contained in the exhaust gas from which PM and SOx are removed while passing through the scrubber 200, so that only the dried exhaust gas passes therethrough. With the included SOx and residual PM completely removed, it is possible to discharge only the purified exhaust gas as much as possible, which will greatly help in building a reliable and environmentally friendly total gas cleaning system.

In addition, the first unit 100 according to the present invention is formed on the lower side of the first body 110 includes a cleaning liquid discharge unit 130 through which the cleaning liquid used for purification of the exhaust gas is discharged, the cleaning liquid discharge unit ( 130) is inserted into the bottom surface of the first body 110 to protrude toward the inner direction of the first body 110, and accordingly to the exhaust gas by the cleaning liquid received in the bottom of the first body 110 By containing PM and SOx adsorbed at the same time, it will be possible to achieve an effect of significantly increasing the reduction rate of PM and SOx contained in the exhaust gas.

In addition, according to the present invention, the height (h) from the inner bottom surface of the first body 110 to the top of the cleaning liquid discharge unit 130 is adjusted so that the liquid level of the cleaning liquid accommodated in the bottom of the first body 110 can be adjusted. By further comprising a height adjustment unit 170 to adjust, it will be able to help in the construction of a device and system with high versatility corresponding to the capacity of various cleaning solutions.

As described above, the present invention together with sulfur oxides and fine dust to enable the construction of a total gas cleaning system capable of simultaneously reducing sulfur oxides and fine dust contained in exhaust gas discharged from offshore plants or marine combustion facilities. The basic technical idea is to provide a centrifugal cyclone embedded in a scrubber to reduce.

And the present invention is not limited to the described embodiments, it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
