AI Technical Summary

Technical Problem

Existing diaphragmless electrolyzers suffer from problems such as short circuits between the cathode and anode plates, high voltage due to bubble accumulation, high energy consumption, low electrolysis efficiency, scale deposition, and uneven ion transfer, which are particularly severe in small electrolyzers.

Method used

An insulating mesh with perforations is used to separate the cathode and anode plates. The insulating mesh is designed with a wave-like structure and has dynamic turbulence and scraping functions. It expands and contracts under the action of water flow to avoid short circuits, promote the discharge of air bubbles, inhibit scale deposition, and enhance ion transfer.

Benefits of technology

It effectively avoids short circuits, improves electrolysis efficiency and stability, reduces energy consumption, inhibits scale deposition, and enhances ion transfer efficiency and pH stability.

Abstract

The application discloses a diaphragm-free electrolytic cell, which comprises a cell body (1) with an electrode chamber (110), a pair of electrode sheets (3) arranged at intervals in the electrode chamber (110), and a cathode sheet (3a) and an anode sheet (3b). The electrode chamber (110) is provided with an insulating screen (4) for separating the cathode sheet (3a) and the anode sheet (3b). The insulating screen (4) is provided with a plurality of screen holes (411) for fluid. Compared with the prior art, the diaphragm-free electrolytic cell can avoid short circuit caused by the contact between the cathode sheet and the anode sheet, accelerate exhaust, inhibit scale deposition, and accelerate ion transfer.
