Nevertheless; Before and after “COD 5 and 00; pH Return seawater out to the sea to adjust conditions (pH if needed; with water” (effluent seawater similar); the outgoing seawater (outbound seawater) is mixed Discharged pure sea in some cases. Discharged and discharged seawater mixing channel structure as a channel merging system from During which the outgoing seawater and a fluid stream or fluid transport pipe flowing from the Alla tower (3835 discharge channel) dilute the outgoing seawater through which the seawater streams dilute with each other. And in, and return it to the sea as long as the amount of desulfurization seawater From the VO desulfurization tower the treatment is generally large; a mixing channel combination is used in which a fluid stream or a small pipe is combined

YY - - Let the fluid have a channel area with a relatively small cross-sectional cross-section with a discharge channel having a channel area with a relatively large cross-sectional cross-section. A mixing channel configuration according to the above-mentioned channel merging system will be briefly described by referring to Figures 14 to TY© in the channel combination used for mixing shown in Figures “Yo 5 19 Discharge Conjugation

In addition, as shown in Figure YY, the discharge channel 1 is provided with a length suitable for mixing L from the junction of ? Y fluid conduit

0 Mixing length 1. This is the length of the spillway 1 needed to mix the outgoing seawater and the softened seawater mixed with it to get a diluted seawater; whereby the conditions of each are controlled at a predetermined level or less; Their concentration is controlled to be approximately equal. The outgoing seawater flowing into spillway 1 is then mixed almost uniformly with grouted seawater along the mixing length (LL) and thus the mixed seawater thus obtained is returned to the sea.

It should be noted that no references have been previously published on a mixing channel structure that can reduce the mixing length 1. required to obtain seawater mixed more or less uniformly by mixing diluted seawater and effluent seawater© from the desulfurization tower and then returning it to the desulfurization tower. the sea. The general description of the invention, however, according to the configuration of the channel used for mixing and according to the channel merging system “excluded_is mentioned above in the relevant art; Seawater Ada is supplied from the lateral surface of discharge channel 1 for mixing; Which requires a large amount of mixing 1, to obtain draft water 0 mixed almost uniformly. It is thought to be motivated by the merging of diluted seawater with seawater emerging from the side surface; The diluted seawater flowing into the spillway 1 is greatly affected by the outgoing seawater flow; So the diluted seawater does not easily reach (pass to) the side wall opposite to the side that is fed with seawater Ad which is in the direction of the width of the discharge channel 1. In addition; When installing a downspout 1 that has a large length for the .1 mixture described above; Besides the uC VO site, this also entailed a significant construction cost. Therefore, when the outgoing seawater from the desulfurization tower is returned to the sea to be returned to the mixed seawater that meets the predetermined environmental standards by Jalil, the main obstacles surrounding this are the need to prepare a facility area on site; increased processing costs; and the like. in addition to; may be

Since irregular currents 31 are present in this case; Perpendicular thin plates are provided on the flat portion in an overlapping manner.

In the second embodiment shown in Figures 17 and 17, YY irregularities are provided along zigzag lines placed with a predetermined slope in the flow.

© Due to the presence of the irregular TY in this case; For example; Thin plates each folded as shown in the cross sectional drawing of Fig. 117 shall be additionally fixed to the surface of the flat part Ye; Yay from the TY described above; For example, JB can provide two irregular streams SIE "ab" formed repeatedly for folding thin plates 040 inscribed shapes on the flat part 010 as in the third example 0 rate shown in tables 08 or 81b, respectively. When irregular currents (TY 5 oF) and © FY are used in the first three examples, for example, eddies are generated in the outflow of seawater and the inflow of mixed seawater » and turbulence is generated in the flow in the flow; thus, the mixing process between the outgoing seawater and seawater (Ada) is greatly improved.

0 according to the duct fittings used for mixing in previous models; When the mixed seawater obtained by diluting the seawater discharged in the discharge channel 11 is returned with the diluted seawater flowing into the fluid conduit 11 or the fluid-conducting tube vy which is Combine it with seawater leaving the channel side surface to “ya” and as long as the diluted seawater is combined with seawater leaving at a level lower than the water level;

mm 11

this? - the discharge channel is regulated in the lower channel surface part of discharge channel 11 in the direction of channel 7 at the confluent portion of the diluted seawater with the discharge channel; A fluid mixing method can be obtained where the effect of the outgoing seawater flow is less on the diluted seawater mixed with it from the channel side surface ¢ and thus the diluted seawater flowing into the drainage channel 11 can easily reach the side wall at the side corresponding in the direction of .Wh channel width plus ely according to the fluid mixing channel structure and mixing method of the present invention; For example; As in this case, in which the mixed seawater obtained by mixing the outgoing seawater from the desulfurization tower Ve and seawater Ada is returned to the sea, the mixing length L required to mix two types of fluids; As a result; The mixing process can be done efficiently. and when reducing the mixing length .1 as described above; In unit facilities that require a channel assembly for fluid mixing; Js discharge channel 11 channel or fluid conduit VY fluid conduit Site size and equipment cost can be reduced in particular »; As long as the downstream channel 11 at the downstream side VO of the OF can be reduced, great design freedom can be enjoyed. in the models described above; The composition will be described as a mixing channel in which a large volume of discharged seawater (influent seawater) discharged from the desulfurization tower of a gas desulfurization facility is mixed through a discharge pipe with pure, diluted seawater for the dilution process; Nevertheless; The present invention is not limited to this. Nevertheless; The present invention can also be applied to a

- 10 together efficiently to form a fluids a channel combination for mixing and a mixing method to mix two other types of fluids a mixture with nearly consistent properties and concentration. on previous models and can be radically modified without going out Mall In addition to that; The invention is not limited to the scope and scope of the current invention
