Electrolytic cell device provided with separated cathode and anode chambers and used for preparing ozone water through electrolysis

Abstract

The invention discloses an electrolytic cell device provided with separated cathode and anode chambers and used for preparing ozone water through electrolysis. The electrolytic cell device comprises an electrolytic cell, wherein cathode electrodes and anode electrodes are arranged inside the electrolytic cell; the bottoms of the cathode electrodes and anode electrodes are in complete contact with the bottom end of the electrolytic cell to divide the electrolytic cell into anode chambers and cathode chambers independent to one another; a proton exchange membrane for allowing ions to permeate, but preventing hydrogen from permeating into the anodic area is arranged at the separated part of each anode chamber and the corresponding cathode chamber. Through the adoption of the structural design, the anode chambers and the cathode chambers are separated and not communicated, so that water in the cathode chambers cannot enter the anode chambers, and further, the situation that hydrogen generated in the cathode chambers enters the anode chambers to be in neutralization reaction with ozone O3 is avoided; therefore, the consumption amount of ozone O3 is reduced, the production efficiency of ozone O3 is improved, and the content of ozone O3 is increased.

Description

technical field [0001] The invention relates to the research field of electrolytic cell devices, in particular to an electrolytic cell device for separating cathode and anode chambers for electrolytic preparation of ozone water. Background technique [0002] The application of electrolyzed water was used by NASA in manned spacecraft to supply oxygen to astronauts as early as the 1970s. Especially after the 1980s, the application of solid polymer electrolyte (SPE) technology in the electrolysis of water to produce hydrogen and oxygen has been promoted. Using general conductive materials as electrodes, electrochemical reactions can occur on the anode and cathode surfaces to generate oxygen and hydrogen respectively. The conductive diamond material has been proved to have excellent electrochemical properties. Using conductive diamond as an anode can make ozone directly soluble in water, referred to as ozone water. [0003] Chinese patent CN20061009226.7 and CN20118006557.9 ad...

Problems solved by technology

[0003] Chinese patent CN20061009226.7 and CN20118006557.9 adopt diamond electrodes to prepare ozone water, but the anode area and the cathode area are not separated, and the anode chamber and the cathode chamber are connected (such as figure 1 As shown), the ozone generated after electrolysis will mix from the connected area, so that the hydrogen in the water is oxidized by the ozone, and the ozone content is diluted at the same time, resulting in low ozone production efficiency and low ozone concentration of the generator
