Description

Electrolyzer {ELECTROLYTIC CELL}

The present invention relates to an electrolytic cell, and more particularly, to an electrolytic cell capable of uniform flow of an electrolytic solution flowing inside the electrolytic cell.

In general, an electrolytic cell that produces caustic soda and chlorine gas through an electrochemical reaction that occurs in an electrode assembly in which anode, separator, and anode are joined consists of 100 or more unit cells.

The main energy loss factors related to the electrolysis of the electrolyzer may be the wide gap between the anode and the cathode, the low active surface area of the electrodes, the resistance to ion flow between the electrodes, and the inefficient structure of the electrolyzer.

The amount of electrical energy required for ion conduction in the electrolytic cell is proportional to the distance between the anode and cathode separated by a separator. Energy loss can be reduced by reducing the gap between the anode and the cathode and minimizing the internal resistance. In addition, when the surface area per unit volume of the electrode is large, energy efficiency can be increased and the electrolytic cell can be miniaturized.

In the electrolysis process, an electric current flows from an electrode having one polarity to an electrode having an adjacent opposite polarity through the electrolyte and the separator. . Energy loss may be reduced as the flow of ions having an electrical charge between the electrodes is smoother.

In general, the electrolyte may be supplied to the electrode assembly through a plurality of flow paths (about 20) formed in the electrolyte supply unit. The flow rate of the electrolyte supplied to the electrode assembly through the flow path is unevenly distributed as the electrolyte flows into the flow path furthest from the flow path formed at the position closest to the inlet through which the electrolyte is introduced from the outside in the electrolyte supply unit. There was a problem.

This non-uniform flow rate distribution of the electrolyte may make the electrochemical reaction unstable inside the electrode assembly, thereby increasing power consumption of the electrolyzer, and thus increasing the operating cost of the electrolytic cell. In addition, there was a problem in that the maintenance cost of the electrolyzer increases by shortening the product life.

Also, the input path 1220 may include a plurality of primary distribution holes 1221 .

The primary distribution hole 1221 is formed by being perforated in a plurality on the outside of the input path 1220 disposed inside the chamber unit 1210 , and the electrolyte flowing in the input path 1220 is supplied to the chamber unit 1210 . can be ejected with The ejected electrolyte may be filled in the chamber unit 1210 . The primary distribution hole 1221 is parallel to the longitudinal direction of the input passage 1220, and is opposed to each other with an imaginary plane s in the vertical direction passing through the center p of the input passage 1220 therebetween. 1220) may include being perforated in a pair on the outside. Specifically, the pair of primary distribution holes 1221 may be formed in a horizontal direction on the side of the input path 1220 .

The chamber unit 1210 may have an internal space for storing the electrolyte. An input path 1220 may be inserted into the chamber unit 1210 so that the primary distribution hole 1221 is positioned therein. The interior of the chamber unit 1210 may be filled with the electrolyte ejected through the primary distribution hole 1221 .

Therefore, the electrolyte ejected from the primary distribution hole 1221 may not be directly supplied to the electrode assembly 1100 through the secondary distribution hole 1211 . Accordingly, the electrolyte supplied into the chamber unit 1210 through the primary distribution hole 1221 completely fills the interior of the chamber unit 1210 , and then the electrolyte solution continuously supplied through the primary distribution hole 1221 . The electrolyte inside the chamber unit 1210 may be ejected into the secondary distribution hole 1211 under the pressure of , and supplied to the electrode assembly 1100 .

The secondary distribution hole 1211 may be formed at a position corresponding to the pair of primary distribution holes 1221 and the input path 1220 in the longitudinal direction. Therefore, after the electrolyte supplied from the primary distribution hole 1221 is filled in the chamber part 1210, it can be induced to be smoothly supplied to the electrode assembly 1100 through the secondary distribution hole 1211 without a bottleneck. .

Accordingly, as the electrolyte is ejected at a position corresponding to the lower end of the bent portion 1110 , the electrolyte may be divided and flowed to both sides of the bent portion 1110 .

The through hole 1212 is formed by passing the input path 1220 through the chamber unit 1210 , and may be sealed. By sealing the through hole 1212 , it is possible to prevent the electrolyte stored in the chamber unit 1210 from leaking to the outside.

The discharge unit 1300 is formed on the upper end of the electrode assembly 1100 and may discharge gas generated by an electrochemical reaction in the electrode assembly 1100 to the outside.
