Method for slowing electrolysis bath anion and cation thin film laminar flow and device

Abstract

The invention provides a method for slowing electrolyte tank anion and cation membrane laminar flow and a device thereof, wherein, corresponding inner faces of two shells are provided with pole plates on which cathodes and anodes are correspondingly arranged, center positions on shells or pole plates are provided with water intake flow passages by which two electrolytic spaces are divided into, the raw water flows in through water inlets of the water intake flow passages and is electrolyzed directing to both sides, thereby slowing down the water velocity during the electrolytic process of the alkaline water and the acidic water, helping the split flow of the alkaline water and the acidic water and avoiding the mixed flow phenomenon.

Description

technical field [0001] The slow flow method and device for the laminar flow of anion and cation films in an electrolytic cell of the present invention are mainly applied to the slow flow technology of the laminar flow of anion and cation films in an electrolytic water machine. Background technique [0002] see figure 1 Shown: It is a schematic diagram of the shunting state of the invention patent case of Taiwan Patent Publication No. 301644 "Diaphragmless Electrolyzer for Electrolysis of Water". According to the scope of the patent application: [0003] Two anode plates 81 and a cathode plate 82 are mainly arranged in the electrolytic cell 80, and water channels 83 and 84 as electrolysis chambers are formed between the anode plate 81 and the cathode plate 82, and water is passed through the water channels 83 and 84 for simultaneous electrolysis. water to produce acidic water and alkaline water, the anode plate 81 is provided with a slit 85 for the acidic water recovery por...

AI Technical Summary

Problems solved by technology

[0007] 1. The unit area of ​​the water inlet and outlet water of the electrolytic cell is equal, that is, the flow velocity entering the electrode plate inlet is equal to the flow velocity leaving the electrode plate outlet. Since the water outlet flow velocity cannot be slowed down, it will be excited at the branch of the alkaline water and acidic water outlet. Turbulent flow, causing alkaline water and acidic water to easily mix, not suitable for high flow rate water

[0008] 2. It is impossible to guide the diversion of cations in alkaline water and anions in acidic water, which will easily cause the mixed flow of alkaline water and acidic water

[0009] 3. Since the electrode plate itself is not equipped with reinforcing ribs, the electrode plate is directly welded to the electrode plate when making the electrode, so the electrode plate after welding will be warped and twisted, resulting in the electrode plate being unable to maintain In a certain horizontal plane, the gap between the two electrode plates will inevitably increase, and it is not suitable for electrode tanks without diaphragms and spacers with relatively small intervals.
