Compatible sea water electrolytic cell with a transparent body for Power Plant

The present invention relates to a seawater electrolytic cell for a power plant, and more specifically, to the electrolytic treatment of seawater for the purpose of removing various sea creatures contained in seawater, which is a cooling water introduced to a plurality of waste steam of the power plant, seawater inflow observation Improves the electrolysis efficiency of seawater by uniformly stabilizing the flow of seawater flowing into the electrolytic cell from the side and moving to the side, and stably fixing and installing the electrode plate disposed inside the electrolytic cell, and assembling and disassembling easily. It relates to a transparent seawater electrolyzer for power plants with configured compatibility.

The power plant is located mainly on the coast, where condenser condensate is freely supplied. The hot and high-pressure steam generated by the steam boiler spins the turbine and cools the waste steam to convert it back into the liquid phase. use. However, since various sea creatures exist in such seawater, a kind of pretreatment process is required to use such seawater as cooling water. A method of killing seawater organisms in seawater by electrolyzing seawater to generate sodium hypochlorite is mainly adopted.

6 is a front view showing an example of a conventional seawater electrolytic cell, Figure 7 is a perspective view of an electrolytic cell according to another conventional example.

The electrolyzer of FIG. 6 forms a plurality of seawater inlets 2 and seawater outlets 4 above and below the outer circumferential surface of the casing C, and a plurality of seams in the inner space of the casing partitioned by portions corresponding to the inlets and outlets 2 and 4. The electrolytic decomposition may be performed by embedding the electrode plate stack structure, and the seawater introduced from the inlet 2 passes through the space between the plate-shaped electrodes 22 and is immediately discharged to the outlet 4 directly above. However, in the electrolyzer having such a structure, turbulent water is formed in the electrolyzer because seawater introduced from the inlet side by a booster pump (not shown) passes through the electrode 22 at a very high speed and pressure and is discharged to the outlet 4. There is a shortcoming of sufficient time for decomposition to decrease the electrolysis efficiency, and as it is discharged as it is to the outlet (4) in the state of low sodium hypochlorite production concentration in the electrolytic cell has a disadvantage that the microbial sterilization effect in the sea water is reduced.

Even in the case of the electrolyzer of FIG. 7, since the above-mentioned problems remain as it is, the electrolytic ability is lowered, and there is still a problem that the microbial sterilization effect in seawater is not satisfactory.

Therefore, the flow of seawater flowing into the electrolyzer at high pressure and high speed by a booster pump or the like is stabilized and uniformly distributed to improve the electrolysis efficiency of the seawater, simplifying the configuration of the electrode plate installed inside the electrolyzer, and simultaneously improving the electrode plate. There is a need to develop an electrolytic cell having a structure that can be stably supported.

It is an object of the present invention to replace a square electrolyzer, which is mainly installed in an existing power plant, for example, a single pole square electrolyzer for DC current 5,500 A and DC voltage 35 V, without replacing the rectifier. It is not only compatible so that it can be used, but also it is designed to suppress the turbulent flow of seawater in the electrolyzer and induce laminar flow to stabilize and evenly flow the seawater. To provide.

Another object of the present invention is to provide a seawater electrolyzer for a power plant designed to increase the sealing force so that the seawater inside the electrolyzer does not leak, to stably support the electrode plate, and to easily assemble, dismantle and maintain the electrode plate structure.

In order to achieve the above object, in the present invention, it is formed of a transparent synthetic resin material to observe the inside, the casing flange 115 is formed at both ends, the sea water inlet pipe 171 on one side of the outer peripheral surface to communicate with the inside A casing 110 having a hollow cylinder shape formed on the other side thereof so that the seawater outlet pipe 172 communicates with the inside thereof; A disk-shaped partition partition wall disposed in plural in the longitudinal direction of the casing to divide the casing inner space into a plurality of spaces; An electrode plate (161, 162) arranged in a plurality of spaces divided by the divided partitions and configured by stacking a plurality of plates to be spaced apart from each other by a predetermined interval; It is attached to both side end surfaces of the electrode plate so as to be perpendicular to the plate surface of the stacked electrode plate located in the space where the seawater inlet pipe is formed among the divided spaces inside the casing, and a plurality of plate-like plate body 131 The seawater distribution hole 132 of the pair of seawater powders 130 are formed through; A coupling flange 117 which bolts to the casing flange 115 to seal the inside of the casing; And electrode pins 163 and 164 electrically connected to the electrode plates 161 and 162 and formed at one end thereof to protrude to the outside through the coupling flange 117. Disclosed is a transparent seawater electrolyzer for power plants having a compatibility, characterized in that the configuration, including.

Here, it is preferable that the pair of seawater powders 130 installed on both side end faces of the electrode plate are fixedly coupled to each other by the powder fastening bolts 133a and the nuts 133b.

In addition, the side fixing plate 140 is attached to the outer side of the outermost electrode plate of the plurality of stacked electrode plates (161,162), the side fixing plate 140 has a cross-section 'b' shaped side fixing bracket 145 It can be fixed to the partition partition wall (120) by.

The partition partition wall 120 is formed of an elastic material synthetic resin or a rubber packing material 123 having a diameter larger than the diameter of the wall as being coupled to the disk-shaped wall 121 and the plate surface of the wall. desirable.

End portions of the seawater inlet pipe 171 and the seawater outlet pipe 172 may be coupled to the expansion joint pipes 173 and 174 to be detachable.

According to the present invention, since the flow of seawater flowing into the electrolyzer through the seawater inlet pipe by a booster pump is stable and uniformly distributed and flowed into each compartment, the seawater stays between the electrode plates and the laminar flow is generated in the electrolyzer. Due to this it is possible to increase the sodium hypochlorite production efficiency. Therefore, the microbial treatment in the seawater used as the cooling water can be surely prevented, and the damage caused by the harmful organisms accumulated in the cooling system can be prevented.

1 is a partial perspective view of a seawater electrolytic cell for a power plant according to the present invention, Figure 2 is a front view of the seawater electrolytic cell for a power plant according to the present invention.

In the present invention, for convenience of description, the left and right directions, the up and down directions, and the front and rear directions are defined based on the electrolytic cell of FIG. 2. The front-rear direction shall mean the direction perpendicular to the ground.

Electrolyzer 100 of the present invention is largely composed of the outer casing 110 and the inner electrode plate (161,162).

The casing 110 may have a hollow cylindrical shape having a circular cross section, and may be formed of a synthetic resin made of a transparent material such as acrylic so as to easily observe a scale accumulated in the electrode plates 161 and 162 installed therein. Casing flanges 115 having a diameter larger than the diameter of the casing 110 are formed at both end (left and right) ends of the casing 110. The casing flange 115 is preferably formed integrally with the same material as the casing 110.

A coupling flange 117 is coupled to the casing flange 115 by flange fastening bolts and nuts 118a and 118b. The coupling surface of the casing flange 115 and the coupling flange 117 is placed in the sealing material of the synthetic resin or rubber material of the elastic material so that the fluid flowing inside the casing 110 does not leak. Electrode pins 163 and 164 to be described later penetrate and couple to the coupling flange 117. Electrode pins 163 and 164 are installed on the coupling portion of the electrode pins 163 and 164 and the coupling flange 117 by sealing a synthetic resin or rubber material. ) So that the seawater flowing inside the casing 110 to the coupling site does not leak.

The interior of the casing 110 is divided into a plurality of spaces by the partition partition wall 120. The partitioned partition wall 120 is composed of walls 121 and 122 having a disk shape and a packing material 123 between the walls 121 and 122. The walls 121 and 122 are formed of an insulating material such as a synthetic resin material having rigidity, and the packing material 123 is formed of a material such as a synthetic resin material or rubber having elasticity. The diameter of the packing material 123 is preferably formed to be slightly larger than the diameter of the walls (121, 122). That is, in the case of the packing material 123, the diameter of the packing material 123 is slightly larger than the inner diameter of the casing 110 so as to be tightly sealed. By doing so, the seawater can flow only between the electrode plates 161 and 162 to be described later between the spaces divided by the partition partition walls 120.

The space divided per unit casing by the partition partition wall 120 is preferably about 6 to 14, but is not limited thereto.

FIG. 3 is a cross-sectional view along cut line III-III of FIG. 2. In each divided space of the casing 110, a plurality of electrode plates 161 and 162 may be stacked to be spaced apart from each other by a predetermined interval. In the embodiment of the figure, the electrode plates 161 and 162 are erected perpendicular to the ground, and are configured to be stacked in plural in the front-rear direction. The electrode plates 161 and 162 are a mono-polar method in which an anode plate and a cathode plate are alternately arranged in front, rear, left, and right directions, or bipolar having both an anode and a cathode in one electrode plate. (bi-polar) may be adopted. Since the arrangement of the electrode plates of the monopolar and bipolar methods corresponds to a known concept, a detailed description thereof will be omitted.

The electrode plates 161 and 162 extend and support the partition partition walls 120. The left and right outermost electrode plates 161 and 162 are electrically connected to the electrode pins 163 and 164.

The electrode plates 161 and 162 are supported by the partition partition wall 120 and additionally fixed and supported by a separate side fixing plate 140. The side fixing plate 140 is a plate-shaped frame, which is configured to press and support the plate surfaces of the electrode plates 161 and 162 of both side surfaces (the outermost electrode plate in the front and rear directions) positioned in each divided space inside the casing 110. It is arranged extending in the longitudinal direction of 110.

The side fixing plate 140 is fixedly coupled to the partition partition wall 120 by a side fixing bracket 145, which is a kind of angle having a cross section 'a'. In the drawings, reference numerals 145a and 145b denote side fixing bolts and nuts, respectively.

A seawater inlet pipe 171 is formed at the lower left end of the outer circumferential surface of the casing 110 to communicate with the inner space, and a seawater outlet for discharging the seawater electrolytically treated inside the casing is provided at the upper right end. 172 is formed to communicate with the interior space. That is, the seawater inlet pipe 171 is formed below the first space on the left side of the internal space divided by the partition partition wall 120, and the seawater outlet pipe 172 is formed above the last space on the far right side. .

4 is an external perspective view of the seawater powder according to an embodiment of the present invention, Figure 5 is an external perspective view of the seawater powder according to another embodiment of the present invention.

Seawater powders 130 are fixedly attached to both side ends (upper and lower in FIG. 1) of the electrode plates 161 and 162 positioned in the divided space having the seawater inlet 171 directly below. The seawater agar powder 130 is formed by penetrating a plurality of seawater distribution holes 132 in a plate-like plate body 131 in a rectangular shape, to stabilize the flow of seawater flowing into the flow and evenly distributed in each divided space It is for. In the drawings, reference numeral 133c denotes a bolt fastening hole.

A booster pump (not shown) is typically used to lift seawater from the sea, which is the source of water intake, and transfer it into the electrolytic cell 100. The seawater pumped into the casing through the seawater inlet pipe 171 by the booster pump has a very high flow rate. Thus, the seawater introduced through the seawater inlet pipe 171 is electrolytically processed through each of the divided spaces at a high speed and then quickly discharged through the seawater outlet pipe 172. However, since the seawater pumped at a high pressure by the booster pump flows out of the casing 110 at a too high speed, the electrolysis does not occur sufficiently between the electrode plates 161 and 162. In addition, conventionally, since the seawater flowing at a high speed and high pressure forms turbulence and drift inside the casing 110, the electrolytic treatment efficiency is lowered. Thus, in the present invention, seawater agglomerates 130 are provided at both side ends of the electrode plates 161 and 162 directly above the seawater inflow pipe 171 into which seawater is first introduced, thereby realizing stabilization of the seawater and uniform flow distribution. That is, while the seawater flowing in between the electrode plates 161 and 162 through the seawater inlet pipe 171 passes through the seawater distribution hole 132 of the seawater powder 130, the flow rate is calmed and stabilized. Thus, sufficient time and area are allowed for electrolysis in the first space. That is, it is possible to prevent the phenomenon that the seawater is left as it is along the main stream formed by the drift or turbulent flow due to the seawater mycelium 130. The seawater stabilized in the first space is subjected to electrolysis while uniformly flowing between the electrode plates 161 and 162 in the next adjacent space without generation of drift.

The pair of seawater powders 130 attached to both side ends of the electrode plates 161 and 162 are fixedly coupled to each other by the powder powder fastening bolt 133a and the nut 133b. Therefore, the coupling structure is simple and the assembly and disassembly are free.

The rod-shaped upper fixing frame 151 and the lower fixing frame are provided at both side ends (upper and lower ends of FIG. 1) of the electrode plates 161 and 162 provided in a space other than the leftmost division space where the seawater inflow pipe 171 is located. 152 is installed and fixed by the fixing bolt 153 and the nut 154.

As shown in FIG. 2, expansion seam pipes 173 and 174 having bellows shapes are coupled to ends of the seawater inflow pipe 171 and the seawater outflow pipe 172. The expansion joint pipes (173, 174) may be a well-known pipe is formed so as to be able to be bent freely, and flanges (173a, 173b, 174a, 174b) for connecting to the pipe to be connected to both ends are formed. That is, as shown in the drawing, one flange 173a of the expansion joint 173 is bolted to the flange 171a of the seawater inlet pipe 171, and the connection pipe 175 is connected to the other flange 173b of the expansion joint. Connection of the pipe is performed by bolting the flange 175a of the. This makes it quick and simple to connect or disconnect the seawater inlet pipe 171 and the seawater pipe connected to the booster pump regardless of the position or shape of the electrolytic cell 100 or the pipe.

In addition, it can absorb the shock of the fluid generated during the sudden start of the booster pump, so that it can help to stably absorb the sudden pressure rise or pressure wave inside the electrolyzer, and also helps the life of the device.
