Field of the Invention The present invention relates to a flue gas desulfurization apparatus suitable for use in a generator set for burning coal, crude oil and heavy oil, and more particularly to a flue gas desulfurization apparatus which is desulfurized by seawater method. [Prior Art] In the generator set using coal or crude oil as fuel, the combustion exhaust gas (hereinafter referred to as "boiler exhaust") discharged from the steel furnace needs to remove the sulfur dioxide contained in the boiler exhaust gas. (s〇2) and other sulfur oxides (s〇x) can be released into the atmosphere. The desulfurization method for the flue gas desulfurization apparatus for performing such desulfurization treatment is known as a limestone gypsum method, a semi-dry scrubbing method, and a seawater method. Among them, a flue gas desulfurization device using seawater method (hereinafter referred to as "seawater desulfurization device") is a desulfurization method using seawater as an absorbent. The method is to supply seawater and boiler exhaust gas to the inside of a desulfurization tower (absorption tower) which is vertically cylindrical, for example, and to perform wet-based gas-liquid contact with seawater as an absorption liquid. Things. In this way, the seawater dispersion method of the seawater desulfurization device that desulfurizes the seawater flowing from the upper portion of the desulfurization tower and the combustion exhaust gas rising from the lower portion of the desulfurization tower is known to have a sump type, a filling type, and a spray type. And liquid column type. In the above-described seawater desulfurization apparatus, it is usually used in the desulfurization tower as an absorbent after the seawater inflow waterway (Seawater Oxidation Treatment System: SOTS) is discharged to the nearby sea area. 3 ' For the use of 35 in seawater, it is treated with, for example, decarburic acid (aeration). 132461 .doc 200918152 Here, as a prior example of the seawater desulfurization apparatus, a leaky shed structure as shown in Fig. 1A will be briefly described. In the illustrated seawater desulfurization unit, seawater is supplied from the upper portion of the desulfurization tower 2 and naturally falls, and gas-liquid contact is generated between the boiler exhaust gas supplied from the lower portion of the desulfurization tower 2 and raised. The seawater is in contact with the gas and liquid of the boiler exhaust gas, and the multi-stage porous plate shed 3 which is arranged at a certain interval in the upper and lower directions of the desulfurization tower 2 is used as a wet foundation, and the seawater and the boiler exhaust gas are passed through the perforated plate shed 3. A plurality of holes 4 are achieved. In addition, the symbol 5 shown in Fig. 1 is a seawater supply pipe, 5a is a seawater nozzle, 6 is a seawater outlet for discharging seawater after desulfurization, 7 is for exhaust gas supply port, and 8 is for desulfurization. In the seawater desulfurization unit, the desulfurization tower 2 is disposed above the waterway (s〇ts) 9 and desulfurization exists. After that, the used seawater is discharged from the lower end of the desulfurization tower 2, and is directly drained into the waterway 9 by the seawater outlet 6 to be drained. That is, the seawater for dilution flowing in the water passage 9 is mixed with the used seawater which has fallen from the desulfurization tower 2, and is diluted with seawater used for drainage.卩, the water passage 9' used for seawater flow is used to prevent the flow of the steel furnace from the desulfurization tower 2, and the barrier wall for gas sealing (7) is extended before the position into the water. Therefore, the boiler exhaust gas supplied to the desulfurization tower 2 is blocked by the partition wall ι and the water surface so that it cannot leak out from the space formed on the water surface of the water path 9. In addition, the seawater desulfurization device using other seawater dispersion methods (filling type, etc.), the basic composition of desulfurization by seawater flowing from the upper part of the desulfurization tower 2 and the gas-liquid contact rising from the lower side of the desulfurization tower 2 All the same. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. 2001-129352. The tower 2 is mixed and diluted in the seawater for dilution flowing in the waterway (S〇TS) 9, and when it is flushed into the surface of the seawater for dilution, the boiler is mixed into the boiler in the desulfurization tower 2 due to water surface fluctuation or the like. Exhaust concerns. In this way, the exhaust gas of the boiler which has been used in seawater is mixed, and the bubble flows with the flow of the seawater for dilution, and flows to the outside through the barrier wall H). As a result, a part of the steel furnace exhaust gas leaks from the desulfurization tower 2 to the surrounding environment with the seawater for dilution, which is not preferable. In this way, the flue gas desulfurization device (seawater desulfurization device) using the seawater method is expected to solve the problem that the steel furnace exhaust gas mixed in the seawater surface diluted with seawater can be leaked to the desulfurization tower with the flow of the dilute seawater. The problem outside. The present invention is the result of the above-mentioned situation. The purpose of the invention is to prevent or suppress the incorporation of combustion exhaust gas when the sea surface of the seawater used for diluting the seawater is diluted by the seawater method. Gas), from (4) or minimally inhibit the leakage of combustion exhaust. In order to solve the above problems, the present invention employs the following method. The flue gas desulfurization device of one aspect of the present invention is a flue gas desulfurization device using seawater method for desulfurization by seawater flowing from the upper part of the Qing and the combustion exhaust gas rising from the lower part of the desulfurization tower. It is below the position of the exhaust gas stream of the above-mentioned decoupling, and the line is disengaged. (4) The seawater is digested from the (4) desulfurization tower into the dilute seawater flowing in the waterway to relax the above-mentioned used seawater falling into the aforementioned dilution. =, and the impact mitigation device. The impact of the sea "132461.doc 200918152" according to the flue gas desulfurization device, by using the desulfurization tower after the combustion flue gas flow into the position, the desulfurized used seawater is set to fall from the desulfurization tower, The internal motorized dilution is mixed and diluted with seawater, and the impact force mitigation device that uses the impact force when diluting into the seawater for dilution is used, thereby using the seawater that has fallen from the stone shovel and rushing into the seawater for dilution. Before, or into the dilute, when using seawater, the penetration force against water is reduced by the impact mitigation device. The gp 'impact mitigation device subdivides the used seawater flow (seawater group) from the desulfurization tower to the diluted thin surface, or reduces the flow velocity in the direction of the rushing person to reduce the use of the seawater to the surface. The penetration force. As the impact buffering device in this case, there are grids such as grids, perforated plates, and diffraction gratings that are disposed in the seawater for dilution (in combustion exhaust) or in water (including those that continue from water to water). The type of the seawater in which the gas-liquid contact is carried out in the case of the squirting of the slab, and the squirting of the slab, the squirting type, the filling method, the filling type, the spray type or the liquid column type. According to the invention, the stone is removed from the desulfurization tower by using seawater from the desulfurization tower and diluting the seawater for dilution in 2 after the use of seawater. The seawater is used to pass through the impact mitigation device, and the penetration force of the seawater used in the sea is alleviated. Therefore, it is possible to prevent or suppress the de-slustering and mixing into the used seawater stream, and to mix the flow of the seawater for dilution into the water for dilution of the seawater, and to flow out without leaking from the desulfurization tower. Device. That is, in the flue gas desulfurization unit 132461, which is treated by the seawater method, the desulfurized seawater is dropped into the seawater for dilution, and doc 200918152 is set to reduce the dilution sea X by mitigating the penetration force of the seawater used. The water surface is agitated, so it is very effective to prevent or inhibit the use of seawater to flush into the diluted KJc surface and to burn the exhaust gas to prevent or minimize the leakage of the combustion exhaust gas to the outside of the desulfurization tower. [Embodiment] Hereinafter, an embodiment of the flue gas desulfurization apparatus of the present invention will be described based on the drawings.

The seawater flows out from the plurality of seawater nozzles 5a arranged slightly in the upper plane of the absorption tower 2, and flows out to the perforated panel 3 disposed below. The seawater is subjected to gas-liquid contact through the perforated slab 3, in other words, absorbing sulfur oxides in the exhaust gas of the boiler and removing the used raw water after desulfurization, and using the seawater outlet opened from the bottom surface of the desulfurization tower 2 6 directly falls to the surface of the seawater for dilution flowing in the water passage (SOTS) 9 described later, and is mixed and diluted. In addition, the steel furnace exhaust gas after desulfurization after gas-liquid contact is discharged from the outlet exhaust port 8 of the above-mentioned (four) port of the desulfurization tower 2 to the outside of the desulfurization tower. In the case of the seawater dewatering & 1A, the seawater used for use as an absorbent inside the diluted desulfurization tower 2 is used, and the seawater for dilution is placed in the upper portion of the flowing water channel 9. That is, the desulfurization tower 2 is placed over the waterway 9 and the used seawater outlet 6 of the lower end opening is located at the top of the fire a, and is dropped from the desulfurization tower 2 into the seawater. Dilution into diluted brine by dilution of seawater for dilution. The used diluted seawater is treated in the seawater desulfurization apparatus 5 and the waterway 9 (aeration) on the downstream side of the position. _(4) The implementation of, for example, decarbonation, and the use of a seawater flowing water path 9, palladium ruthenium to prevent the flow of milk from the boiler from the desulfurization tower 2, and a barrier wall for extending the sealing is provided. Therefore, the exhaust gas before the position where the seawater is released is used as the outlet of the seawater, and the (4) exhaust gas is blocked by the barrier wall 10 and the water surface of the crucible, and becomes the blocked state 13246I.doc 200918152 state, so that It cannot be leaked outward from the space formed by the water channel 9 <the first embodiment. Hereinafter, the impact of the present invention will be described with reference to Fig. 6 to the nucleus and the nucleus of the nucleus (hereinafter referred to as the mitigation device T.). The inside of the desulfurization tower 2, such as the opening position of the port 7 One, $9 is connected to the boiler exhaust gas to supply the mitigation of the impact force when the seawater surface is released. _=Into the inflow position of the boiler exhaust gas and the position of the device 20, and the dilute seawater flowing in the waterway 9 The upper position is fixedly supported on the desulfurization tower 2 and 20 is arranged to cover the formation of the helium as the mitigation device. & is used in such a way that the entire area of the seawater outlet 6 is used, the mitigation device 20 is contacted or passed through the dilute seawater. The use of water surface k sea KW uses the seawater flow or the flow group to subdivide' or reduce the flow velocity toward the water surface of the dilution seawater to reduce the penetration force of the used seawater to the water surface. The mitigation device 20 shown in Fig. The grid-like member can be formed by, for example, using seawater. In this case, the grid-like member, for example, as shown in FIG. 4 or FIG. 5, may be a flat grid 21 or as shown in FIG. Shown The layer grid 21' or as shown in Fig. 5, is formed by a multi-layered lattice layer in the up and down direction. In addition, in the case of a laminated structure, the openings 21a are preferably overlapped and overlapped. For a modification of the grid member, for example, as shown in Fig. 6, a perforated plate 22 having a plurality of holes 22 & can be used in the circular plate. In the case of the perforated plates 22, i or a plurality of layers can also be used. In addition, in the case of the construction of the laminated layer 132461.doc • 12-200918152, the holes 22a of the laminated perforated plates 22 are preferably overlapped and overlapped. After the mitigation device 20 is provided, the used seawater that has fallen in the desulfurization tower 2 passes through Grid 2 1 or a grid-like member of the perforated plate 22. At this time, the seawater is passed through the opening 21a of the grid 21 or the hole 22a of the perforated plate 22, and the water flow (flow group) is subdivided while the opening 21a or The hole 22a narrows the falling flow path and causes a pressure loss due to the flow path resistance. Thus, the seawater that has fallen from the inside of the desulfurization tower 2 to the sea surface for dilution is flushed into the seawater for dilution (the subdivision of the water flow) Reduction and flow rate reduction, etc. Since the penetration force is lowered, the water surface of the seawater for dilution can be relaxed under the use of the seawater outlet 6, so that the combustion exhaust gas in the desulfurization tower 2 can be prevented or prevented from being mixed into the seawater for dilution. For the grid-like member of 2G, in addition to the grid 21 or the perforated plate 22, for example, a diffraction grating (not shown) or the like may be used. The seawater desulfurization apparatus ιβ of the first modification shown in Fig. 2, The mitigation device 2 having the same basic structure as the mitigation device 20 is disposed in the water flowing from the seawater for dilution in the water passage 9. The mitigation device 2GA in this case is a barrier wall extending to the seawater for dilution. 〇Fixed support is provided in such a way as to cover all areas enclosed by the barrier wall 10. 3. The damper device shown in the drawing - 2GA' is not only thick in the up and down direction, but is set to a water depth slightly the same as the lower portion of the barrier wall, but is not limited thereto. In other words, for example, in the case where the sheet grid 21 is provided as the tempering device 20A, it may be provided in a water-like manner or in a water having a suitable water depth, and may be appropriately changed. The mitigating device 20A having such a structure can also be subdivided or reduced by using the seawater flow (seawater group) falling from the desulfurization tower 2 to the surface of the seawater for dilution after the water is flushed into the diluted 132461.doc 200918152. The flow rate in the direction of the seawater for dilution is reduced, and the penetration force of the seawater washed into the water surface is lowered. That is, the mitigation device 20A can reduce the penetration force of the barrier wall 1 by subdividing the seawater flow by subdividing or reducing the flow rate of the used seawater flow. The dilution of 3 is caused by the sea water surface. Thereby, (4) the seawater desulfurization device B of the mitigation device 20A can prevent or suppress the pin furnace exhaust gas in the desulfurization tower 2 from being mixed into the seawater for dilution. The seawater desulfurization device (1) according to the second modification shown in Fig. 3 is thinned in the same manner as the above-described mitigation device 20A, and is disposed in the water and slightly higher than the seawater for dilution flowing in the waterway 9. Water depth. The mitigation device 20_ in this case is provided in such a manner that the barrier wall extending to the seawater for dilution is fixed and covers all the areas enclosed by the barrier wall. 'The structure of the mitigation device is fine, after using seawater to flush into the seawater for dilution, 'by using the seawater flow to subdivide or reduce the flow rate to reduce the penetration force into the water surface', so use the seawater outlet 6 Below it is a dilution of the seawater surface that can alleviate the area enclosed by the barrier wall. The seawater desulfurization device 1C having the mitigation device can prevent or suppress the boiler exhaust gas in the desulfurization tower 2 from being mixed into the seawater for dilution. Further, the mitigation devices 20, 20A, and 20B are provided on the water or water of the seawater for dilution of the water passage 9, but in the modified example (not shown), the mitigation device is provided with both the 7jC and the water. , or, a mitigation device for water and medium. 7 In addition, for the area covering the mitigation devices 2〇, 2〇A, 2〇B, from the viewpoint of 132461.doc 200918152 effective water suppression, if the kiU is right on the water, it is best to cover the desulfurization tower 2 ^ 吏It is preferable to cover all the areas surrounded by the barrier wall 1 in the case of using seawater, or in water, but it is not particularly limited. <Second Embodiment> Hereinafter, ηπ will be described in the second embodiment with respect to the mitigation device of the present invention. In addition, the same components as those of the above-described embodiment U are denoted by the same reference numerals, and the detailed description thereof will be omitted. The figure of Dingzhi's seawater deguay device 1D has a mitigation device 3 附 attached to the funnel as shown in FIG. The mitigation device 30 with the rushing and weighing plates has a funnel portion 31 and a receiving plate 32. The funnel part 3! is the desulfurization tower 2; (4) the bottom of the seawater outlet 6 is funnel-shaped. The funnel part 3! in this case is formed to be reduced as the bottom of the used seawater outlet 6 below, and has a desulfurization tower. The bottom surface 2a of the inclined surface which is inclined downward at the lower end of the side wall of the side wall of the side wall, and the outlet flow path η which is open at the center of the axis of the desulfurization tower 2 at the lowest point of the bottom surface 2a of the inclined surface. Further, the inclined surface of the bottom surface 2a is preferably as gentle as possible from the viewpoint of suppressing the flow velocity under the flow. The outlet flow path 33 of the funnel portion 31 is a cylindrical flow path that continues to the seawater for dilution. Above the outlet flow path 33, a disk-shaped platen 32 larger than the inlet opening area of the outlet flow path 33 is provided slightly in line with the axial center position. The gap between the parent plate 3 2 and the bottom surface 2 a can be formed as a gap of the flow path using the sea water and is fixedly supported at a position lower than the boiler exhaust supply port 7 into which the boiler exhaust gas is introduced, for example, by the bottom surface 2a. It is mounted on a plurality of support members (not shown). 132461.doc •15- 200918152 By using the mitigation device 3〇, the used seawater dropped in the desulfurization tower 2 is impacted at the center portion and the suction plate 32, and is impacted on the peripheral portion and the bottom surface 2a. As a result, the seawater is used under the center tribe, and the falling speed is lowered by the punching plate 32, and the flow direction is changed, and the flow is directed to the peripheral portion by the upper surface of the receiving plate 32. Thus, from the end of the receiving plate 32 to the bottom surface 2a. fall. At this time, the falling speed is greatly reduced as compared with the falling speed of the falling plate 32. Γ:
另方面，周邊部落下之使用過海水，因底面2a之傾斜 面使落下速度略降低並改變流向，與從受衝板32上落下之 使用過海水匯合流向出口流路33。該情形之流速，因使用 過海水在出口流路33之入口部周圍略均等分散，且，沿較 平緩之傾斜面流動，故流速較小。 如此，從出口流路33流出之使用過海水，其大部分沿出 口流路33之壁面流下，故可緩和㈣過海水沖人稀釋用海On the other hand, the seawater is used under the surrounding tribes, and the inclined surface of the bottom surface 2a slightly lowers the falling speed and changes the flow direction, and merges with the used seawater falling from the receiving plate 32 to flow to the outlet flow path 33. The flow rate in this case is slightly distributed around the inlet portion of the outlet flow path 33 by the use of seawater, and flows along the gentle inclined surface, so that the flow velocity is small. As a result, most of the used seawater flowing out from the outlet flow path 33 flows down along the wall surface of the outlet flow path 33, so that it can be alleviated (4)

Therefore, the 'use of seawater mixed with dilution seawater for dilution' merges smoothly inside the outlet flow path 33 of the front-end flushing (four) seawater, so that the sinking of the seawater surface by the sinker using seawater is suppressed. To a minimum. Therefore, it is possible to prevent or suppress the steel furnace exhaust gas in the desulfurization tower 2 from being mixed into the seawater desulfurization apparatus 1E of the modification shown in Fig. 9 in the sigma flow path 3 3 Second, the mitigation device 30A is different from the horizontal flow path portion 34 in which the seawater outlet 34a is widened to the upstream of the seawater for dilution. Namely, the crucible is configured to flow backward in the flow of the seawater for the release of the water to be mixed with the dilution water. In K and thin 132461 .doc •16· 200918152 The water is diluted by this, and the vortex is generated by the use of the sea. Therefore, it is mixed and diluted in water, and flows through a relatively short ratio of Hi to the seawater for dilution... "Between the flow paths of the road 9, the mixture of the whole: the ratio can effectively achieve a good mixed state." In addition, the seawater desulfurization device of the mitigation device 30A and the steel furnace exhaust gas in the mixture are mixed and diluted for each purpose to prevent or suppress the desulfurization.

Therefore, it is possible to prevent or suppress the use of the seawater flow in the combustion exhaust gas in the desulfurization tower 2, and to exhaust the steel furnace mixed with the seawater for dilution with dilution. The flow of seawater flows out along the waterway 9 and does not leak from the desulfurization tower 2 to the flue gas desulfurization device in the surrounding environment. That is, the seawater method is used to treat the desulfurized seawater after being used in the seawater for dilution. The flue gas desulfurization device is designed to reduce the friction caused by the seawater surface of the seawater by mitigating the penetration force of the seawater used in the seawater. Therefore, it can prevent or inhibit the use of seawater into the combustion seawater when it is flushed into the seawater surface for dilution. The furnace exhaust gas leaks to the outside of the desulfurization tower 2. In each of the embodiments and modifications of the seawater desulfurization apparatus, the seawater flowing down from the upper portion of the desulfurization tower 2 and the combustion flue gas rising from below the desulfurization tower 2 The seawater dispersion method of the gas-liquid contact desulfurization seawater desulfurization device adopts a leak-proof type, but the invention is not limited thereto, and can also be applied to devices such as a filling type, a spray type and a liquid column type. In the mitigation device according to the first and second embodiments, the second embodiment can be combined with the two embodiments in addition to the above-mentioned separate use of 132461.doc • 17-200918152. In the second embodiment, the outlet flow path 33 is described. It has the length of the water into the water. (4) The speed ratio of the seawater used for diluting the seawater used for dilution, and the reduction of the large towel field. Therefore, the length of the outlet flow path 33 can be shortened to the appropriate position on the water surface: no outlet flow path is set at all. In addition, the outlet flow is shortened: 3 or a few are not provided, and the grid-like easing device 2 can be combined.
