Sea water, or to the open sea, and fresh sea water mixed. The aeration which is placed in the discharge path is discharged, and J50645.doc 201127754 is used to perform aeration in which the fine aeration bubbles of the discharge path flow out, and the decarbonation of the discharged seawater is referred to as an "aeration zone". 'If the seawater is discharged by decarbonation as described above? When 11値 and d〇値 are adjusted, the fine aeration bubbles or the organic components contained in the seawater interact with each other to generate a material on the water surface of the discharged seawater flowing in the discharge path. The bubble is discharged from the discharge path and discharged from the seawater to the surrounding sea area (4)*. Because of &, there will be problems with floating in the outer sea in the landscape. Further, even in the case of the flue gas desulfurization apparatus which does not employ the seawater washing method, there is a possibility that the foaming problem occurs due to the seawater property or the like. In order to solve the above problems, there has been proposed a technique for removing foam from discharged seawater flowing in a discharge path (for example, refer to Patent Document 1). As a result, the problem of the landscape caused by the foam is solved by removing the foam from the discharged seawater. [PRIOR ART DOCUMENT] [Patent Document 1] [Patent Document 1] Japanese Patent Application Laid-Open No. Hei No. 5-22092 (Draft of the Invention) [Problems to be Solved by the Invention] However, as shown in the technique of Patent Document 1, 'based on self-discharged seawater The method of removing the foam has the problem that the disposal of the foam component contained in the removed foam is difficult. For example, it is also conceivable that the blister component is separated from the foam and is in the form of a powder or a slurry, and is discarded in the ash disposal site of the power plant. 150645.doc 201127754 method. However, since the fuel burned by the steel furnace differs from the foam component, the method of separating the foam component from the foam, that is, the separation method using the filter, or the separation method using the centrifugal force, has not been established yet, and there is a self-bubble. Beads cannot easily separate this problem from foam ingredients. The present invention has been made to solve the above problems, and an object thereof is to provide a foam removing device which can remove a bubble bed from a sea surface of a discharge path and can easily process a foam component. [Technical means for solving the problem] In order to achieve the above object, the present invention provides the following steps. The present invention relates to a foam removing device i, which is characterized in that it is disposed on a discharge path through which the discharged seawater flows through the power generating device, and is set to #: shouting the water surface of the discharged seawater flowing through the waterway a bubble recovery portion of the floating foam; a bubble recovery tank for inflowing the foam from the foam recovery portion; a defoaming portion for defoaming the foam flowing into the foam recovery tank; and The defoaming unit returns the bubble bed component obtained by the front L; the bubble and the discharged seawater to the discharge port in the vicinity of the discharge path with the foam-flowing person. According to the present invention, the foam recovered from the surface of the discharged seawater flowing through the discharge path to the foam recovery tank is defoamed by the defoaming portion, and the foam component is returned to the discharge water discharged from the foam recovery tank. The ^ of the path is near. Therefore, the foam component can be easily handled as compared with the method of forming the bead component into a powder or separating the exudate from the discharged seawater. In addition, because the foam component is originally composed of organic matter contained in seawater, even if the foam component is returned to the discharge path, the discharged seawater flowing in the discharge path does not contradict the environmental standard. In the above invention, it is desirable that the foam recovery tank is provided with a showering portion for discharging the seawater which flows in together with the bubble. According to the present invention, by stirring the discharged seawater flowing into the bubble recovery tank, the bead component does not precipitate in the foam recovery tank. In other words, since the foam component agitated by the dispensing portion is returned to the discharge path by the discharge portion together with the discharged seawater, it is less likely to precipitate on the bottom surface of the foam recovery tank. In general, in the case where the discharged seawater of the foam recovery tank is not stirred, it is necessary to remove the precipitated foam component because the foamed component of the foaming agent causes a decrease in the available volume of the foam recovery tank. On the other hand, according to the foam removing device of the present invention, since the foam component does not precipitate on the bottom surface of the foam recovery tank, the operation of removing the precipitated foam component or the like can be reduced. [Effect of the Invention] According to the foam removing device of the present invention, the foam from the water surface of the discharged seawater flowing through the discharge path is recovered to the foam recovery tank by the defoaming portion, and the foam component and the foam recovery tank are used. The discharged seawater is returned to the vicinity of the discharge path together, so that the effect of removing the package/end from the sea surface of the discharge path and easily treating the foam component can be obtained.

As shown in Figs. 2 and 5, the defoaming spray nozzle 41 and the defoaming spray pump 42 are mainly provided in the defoaming portion 4. The defoaming spray nozzle 41 is for defoaming the foam crucible by dispersing seawater from above. The discharged seawater is supplied from the defoaming spray pump 42 to the defoaming spray nozzle 41. The defoaming spray nozzle 41 is disposed above the first region 3 1 and the second region 3 2 of the foam recovery tank 3. Further, a known configuration can be used as the configuration of the squirting nozzle 41, and is not particularly limited. The defoaming spray pump 42 is a system that supplies seawater obtained from the discharge path 于 to the defoaming spray nozzle 41. In the present embodiment, an example in which two defoaming spray pumps 42 are provided will be described. Thereby, seawater can be supplied to the defoaming spray nozzle 41 using one of the defoaming spray pumps 42, and the other defoaming spray pump 42 can be used as a preparation. Further, in the case where the amount of the foam B to be defoamed is changed, the number of the defoaming spray pumps 42 which are activated by the change can be made to correspond, and there is no particular limitation. On the inlet side (upstream side) of the defoaming spray pump 42, a deaeration flow rate valve 43 which is basically set to be fully open or fully closed is provided, and on the outlet side (downstream side), discharge water which regulates the inflow or outflow of the pump is provided. The flow rate defoaming flow valve 43 is used. The agitating portion 5 is for preventing the foam component of the foam B from being deposited on the bottom surface of the foam recovery tank 3. The agitating portion 5 is disposed in the second region 32 of the foam collecting tank 3, and an example in which six agitating portions 5 are provided in the present embodiment will be described. As shown in Fig. 2, the agitating portion 5 is mainly provided with a rotating portion 51 and a stirring horse 150645.doc 12 201127754 up to 52.

As shown in Fig. 2, the discharge portion 6 is mainly provided with a discharge flow path 61 and a scum slurry pump 62. The discharge flow path 6 1 is a flow path connecting the second region 32 of the foam recovery tank 3 and the vicinity of the discharge path 10. A scum slurry pump 62 is disposed in the discharge flow path 6丨, and the scum slurry pump 62 is the first of the foam recovery tanks 3. The discharged seawater and the foam component in the region 32 are sent back to the discharge path via the discharge flow path 6. In this embodiment In the state, an example in which two sets of scum slurry pumps 62 are provided is described. Thus, one side of the scum slurry pump 62 can be used to return the discharged seawater and foam components to the discharge path 10, and the other side of the scum slurry. The pump 62 is used as a pre-requisite. In the case where the amount of discharged seawater and foam components returned to the discharge path is changed, the number of the scum slurry pump 62 can be changed by changing the number of the scum slurry pumps 62. There is no particular limitation on the inlet side (upstream side) of the scum charging pump 62. The flow rate valve 63 for discharge is basically provided to be fully open or fully closed, and the flow inflow is provided on the outlet side (downstream side). Or the flow rate discharge valve 63 for discharging the flow rate of the discharged seawater flowing out of the pump. Next, the operation of the bubble removing device 1 including the above configuration will be described with reference to Figs. 1 to 5. For example, the discharged seawater discharged from the flue gas desulfurization device Flowing into the discharge path 1A, as shown in Fig. 1, decarbonation is performed in the aeration zones 12A, 12B, and 12C. Foam B is formed on the water surface WL of the decarbonated seawater, and the foam B is oriented toward the discharged seawater. Downstream As shown in Fig. 2 and Fig. 3, the foam B flowing downstream is intercepted by the foam holding portion 22 below the foam recovery portion 2. The intercepted foam B is guided along the guide portion The bridge truck 23 that reciprocates in the direction across the discharge path 1〇 is recovered to the foam recovery tank 3. Specifically, if the bridge body 23A moves along the guide portion 21 toward the bubble recovery tank 3 Then, the trapped foam b can be collected and collected toward the foam recovery tank 3 by the self-bridging truck body 23 extending to the lower rafter 23B. If the rafter 23B reaches the sloping wall surface 14 provided at the opening portion 13, the accompanying bridge When the carriage body 23A is moved, the lower end of the dice 23B can be lifted upward along the wall surface of the inclined wall surface 14. At this time, the foam B is held by the tweezers 23B, and on the other hand, the discharged seawater flows downward through the gap of the tweezers 23B and the inclined wall surface 14... The bead B is separated from the discharged seawater. 150645.doc -14 - 201127754 - The end of the foam recovery tank $ side of the rafter 23B passing through the inclined wall surface i4 is dropped into the bubble recovery tank 3 by the bubble B held by the mouse 23B. When the right-hand truck 23 arrives at the end of the guide portion 21 on the side of the bubble recovery tank 3, it is made to f; >> 'Purpose the universal reversal' and start moving toward the direction away from the bubble recovery tank 3. . iVl* l At this time, the dice 23B can easily cross the inclined wall surface 14 by bending it. When the test is moved on the discharge path 10, the tweezers 23 Β ', ° prevent the collection of the bubble B in the direction away from the bubble recovery tank 3 by f-curve. The foam B that has fallen into the/recovery recovery tank 3 is initially guided to the first region 3丨 and then guided to the second region 32. In the first region 3 1 and the second region 3 2, the defoaming sprinkling nozzle 41 discharges the seawater to the bubble B, and defoams the foam B. The discharged seawater dispersed from the 'Shaw/pack spray nozzle 41 is supplied from the discharge path 10 by the defoaming spray pump 42. In the present embodiment, an example in which one of the two defoaming spray pumps 42 is applied is described. In this case, the defoaming flow rate valve 43 disposed on the upstream side and the downstream side of the defoaming spray pump 42 that is operated is opened, and is disposed on the upstream side and the downstream side of the stopped defoaming spray pump 42 for defoaming. The flow valve 43 is closed. Therefore, the discharged seawater is supplied to the defoaming spray nozzle 4j via the opened defoaming flow rate valve 43 and the defoaming spray pump 42 in operation. In addition, in FIG. 2, the defoaming flow rate valve 43 which is opened is shown by the blank, and the defoaming flow rate valve 43 which is not closed is blackened. The bubble B contains a foam component such as an organic substance contained in seawater, and if the bubble B is defoamed, the foam component is mixed into the discharged seawater in the bubble recovery tank 3. 150645.doc 15 201127754 In the second zone 32, since the discharged seawater is given by the transfer portion 5, the bead components are also mixed together with the discharged seawater. The 'driving force' causes the rotation ' to be disposed on the shaft portion, whereby it is allowed to flow in, that is, the rotary unit 51 is rotationally driven by the supply of the electric power stirring motor 52. The agitating member at the lower end of the rotary portion 51 that is rotationally driven also rotates in the discharged seawater. In the discharged seawater of the second region 32, a circulating water flow is generated, for example, in the up and down direction, and the foam component having a heavier specific gravity than the discharged seawater is uniformly dispersed in the discharged seawater. The discharged seawater in the second region 32 and the foam component contained therein are returned to the region near the bottom surface of the discharge path i 经 via the discharge passage 6 1 of the discharge portion 6 and the scum slurry pump 62. In the present embodiment, an example in which one of the two scum slurry pumps 62 is applied will be described. In this case, the discharge flow rate valve 63 that is disposed on the upstream side and the downstream side of the scum slurry pump 62 that is operated is opened, and is disposed on the upstream and downstream side flow discharge valves of the stopped slurry pump 62. 63 was closed. Therefore, the discharged seawater is supplied to the defoaming spray nozzle 41 via the opened discharge flow rate valve 63 and the scum slurry pump 62 in operation. In addition, in Fig. 2, the flow valve 63 for discharge which is opened is indicated by a blank, and the flow rate valve 63 for discharge which is closed is indicated by black. Further, the 'slurry slurry pump 62 and the discharge flow rate valve 63 are controlled based on the measurement enthalpy of the horizontal sensor 64 disposed in the foam recovery tank 3 for measuring the water level of the discharged seawater. The slurry pump 62, the defoaming flow rate valve 43, and the discharge flow rate valve 63 may be controlled based on the measurement of the horizontal sensor 64 of the water level of the seawater by the measurement discharge disposed on the foam recovery tank 3. There are no special restrictions. According to the above-described water surface WL of the discharged seawater flowing through the discharge path technology, the foam B recovered to the foam recovery tank 3 is defoamed by the defoaming portion 4, and the foam component thereof and the foam recovery tank 3 are The discharged seawater is returned to the vicinity of the discharge path 10. Therefore, the foam component can be easily handled as compared with the method of separating the foam component as a powder or a slurry from the discharged seawater. Further, since the foam component is originally composed mainly of organic substances contained in seawater, even if the foam component is returned to the discharge path 1 , the discharged seawater flowing through the discharge path 10 does not touch the environmental standard. Since the agitating portion 5 agitates the discharged seawater flowing into the foam recovery tank 3, the foam component does not precipitate in the foam recovery tank 3. In other words, since the foam component agitated by the agitating portion 5 is returned to the discharge path 10 by the discharge portion 6 together with the discharged seawater, it is difficult to precipitate on the bottom surface of the foam recovery tank 3. In general, in the case where the discharged seawater of the foam recovery tank 3 is not stirred, the operation of removing the precipitated foam component is necessary because the precipitated foam component causes the available volume of the foam recovery tank 3 to be reduced. On the other hand, according to the bubble removing device i of the present embodiment, since the foaming component does not cover the bottom surface of the bubble collecting tank 3, it is not necessary to remove the beads of the sinking chamber: • injury work, or It can reduce the frequency of doing work.
