Description

Electrode plate for electrolysis liquid treatment equipment {ELECTROLYSIS FOR MESH TYPE ELECTRODE}

The present invention relates to an electrode plate for an electrolytic liquid treatment apparatus, and more particularly, the contact area when the discharged water and the solution is to pass through the flow path is installed on the flow path for the solution containing the effluent or noble metal that requires electrolysis The present invention relates to an electrode plate for an electrolytic liquid treatment device, which is capable of achieving efficient electrolysis by forming a maximized and regular flow path and smoothly and quickly passing the electrode plate to shorten the electrolytic treatment time.

In general, as industrialization progresses, the amount of water used increases and the air / water pollution becomes more serious, and the necessity of treating wastewater and reusing water is increasing. For example, an electrolysis liquid treatment apparatus is used for sewage treatment, manure treatment, swimming pools, factory wastewater, ballast water, recovery of precious metals in plating processes, and the like.

In other words, for the sewage treatment and water recycling, disinfection to remove bacteria and viruses and the removal of suspended solids in water are becoming important factors. As such, the necessity of sterilization of the effluent generated in the sewage treatment plant is mandated by law, and the conventional effluent sterilization techniques include chlorine disinfection, UV disinfection, ozone disinfection, and electrolysis.

In particular, disinfection using electrolysis is a method in which various chemical substances added or generated during the electrolysis of water are used as a mechanism for killing microorganisms or viruses.

Electrolysis for the purpose of disinfection requires additives (NaCl, Ag, Ca, Br, I), various auxiliary devices for supplying the additives, and depending on the properties of the water to be disinfected and changes in flow rate, Its addition amount is known to be a very complicated disinfection method.

As the method using the electrolysis in the above disinfection method, the "Y" shaped dividing wall dividing the effluent into two streams in front of the effluent inlet of the rectangular discharge tank formed with the inlet and the outlet of the effluent at the same height.壁) is formed so that a plurality of sets of electrode plates are arranged in a staggered manner in each classified space, or the inflow port of the effluent is formed at the lower side and the outlet port is formed at the upper side with a narrow and deep depth. It is formed horizontally on both inner wall surfaces in the longitudinal direction of the discharge tank, and a plurality of electrode plates are arranged upside down, and a plurality of electrode plates are arranged in the discharge tank substantially parallel or inclined with the flow of the discharge water. Electrolytic disinfection facilities for sewage treatment plants for electrolytic disinfection. The purpose of such facilities is to It is installed in the existing discharge tank to provide a more efficient and cheap disinfection treatment means.

On the other hand, since the washing water generated in the plating process contains a large amount of precious metals, recovering such precious metals is a very important treatment process in order to save resources or to prevent contamination by heavy metal-containing waste water.

Therefore, the noble metal is recovered by passing the solution containing the noble metal generated in the plating process through the electrode plate of the electrolysis liquid treatment apparatus. That is, as the solution containing the noble metal passes through the electrode plate supplied with the negative electrode, the cation in the solution diffuses to the surface of the electrode plate, and the noble metal is transferred to the electrode plate by an electrochemical reduction reaction in which the cation receives electrons and is reduced. It is attached and recovered.

The electrode plate is provided in both the electrolysis liquid treatment device for discharged water for sterilization and disinfection or the electrolysis liquid treatment device for recovering the precious metal from the solution containing the precious metal generated in the plating process.

However, the conventional electrode plate installed in the electrolytic liquid treatment device as described above is inclined or zigzag and has a structure in which the effluent or noble metal-containing solution can flow, so that both the effluent or the solution can flow. There is a problem that the electrolytic efficiency is reduced because it flows directly without passing through the electrode plate.

In addition, the solution containing the effluent or noble metal that requires electrolysis passes between the positive electrode and the negative electrode, that is, between the electrode plates. When the electrode plate is installed where a large amount of effluent or solution flows, the flow rate increases and the surface of the electrode plate There is a problem that this is quickly damaged.

In particular, according to the shape of the electrode plate, the mesh-type porous electrode plate crosses thin wires to form a mesh, so that a large amount of effluent or solution comes into contact with the electrode plate for a long time, and foreign matter adheres to the iron plate, and thus the electrode plate and the discharge water or In addition to reducing the contact area of the solution as well as disconnection of the iron wire occurs, there is a problem that the overload of the rectifier causes the operation of the entire device is stopped.

The present invention is to solve the above problems, when the effluent or noble metal-containing solution that requires electrolysis to pass through the electrode plate to maximize the contact area with the electrode plate so that the electrolysis can be made more efficiently An object of the present invention is to provide an electrode plate for an electrolysis liquid treatment apparatus.

In addition, when the effluent or noble metal-containing solution that needs disinfection passes through the electrode plate, a regular flow path is formed so that the effluent or solution can smoothly and quickly pass through the electrode plate to shorten the electrolysis time. The object is to provide an electrode plate for the device.

Is achieved by.

Here, when the first mesh electrode layer and the second mesh electrode layer are stacked, an intersection point where the transverse iron wire and the longitudinal iron wire of the first mesh electrode layer intersect, and an intersection point where the transverse iron wire and the longitudinal iron wire of the second mesh electrode layer intersect. It is preferable to contact this.

In addition, it is preferable that the first mesh electrode layer and the second mesh electrode layer stacked by spot welding are fixed to the second mesh electrode layer laminated with the first mesh electrode layer.

In addition, the stacked first mesh electrode layer and the second mesh electrode layer are preferably rolled up to form a cylindrical shape.

In addition, it is preferable that a fixing ring is fitted to each of the upper and lower ends of the laminated and rolled first mesh electrode layer and the second mesh electrode layer, and the fixing ring is fixed by spot welding.

In addition, the first mesh electrode layer and the second mesh electrode layer are preferably made of titanium.

According to the electrode plate for the electrolytic liquid processing apparatus according to the present invention, when the first mesh electrode layer and the second mesh electrode layer each having a mesh are stacked, the second mesh is intersected or staggered at 90 degrees so that the second mesh is interposed between the meshes of the first mesh electrode layer. The transverse iron wires and the longitudinal iron wires of the electrode layer are visible so that the contact area of the effluent or the noble metal-containing solution requiring electrolysis through the electrode plate is maximized, thereby achieving efficient electrolysis.

In addition, when the meshes of the first mesh electrode layer and the second mesh electrode layer overlap or cross each other as described above, a regular flow path is formed when the effluent or noble metal-containing solution that needs to be sterilized passes through the electrode plate. This smooth and rapid passage through the electrode plate can shorten the electrolytic treatment time.

And a second mesh 122 stacked with the first mesh electrode layer 110 and intersecting the transverse wire and the longitudinal wire, wherein the first mesh 112 and the second mesh 112 of the first mesh electrode layer 110 are formed. The mesh 122 is composed of a second mesh electrode layer 120 that is stacked alternately or staggered 90 degrees.

In other words, the first mesh electrode layer 110 extends in a direction in which horizontal wires are arranged in diagonal lines, and longitudinal wires are arranged in diagonal lines so as to intersect the horizontal wires so that the horizontal wires and the longitudinal wires intersect. As a result, the first mesh 112 is formed.

The second iron electrode layer 120 is formed below the first mesh electrode layer 110 having the first mesh 112 formed in such a manner that the transverse iron wire and the longitudinal iron wire are arranged diagonally.

Similar to the first mesh electrode layer 110, the second mesh electrode layer 120 extends in a direction in which the horizontal wires are arranged in diagonal lines, and the longitudinal wires extend in a diagonal line so as to intersect with the horizontal wires.
