Electrolytic cell device with separated cathode and anode compartments for electrolytic preparation of ozone water

Abstract

The invention discloses an electrolytic cell device for separating cathode and anode chambers for preparing ozone water by electrolysis, comprising an electrolytic cell, a cathode electrode and an anode electrode are arranged in the electrolysis cell, and the bottom of the cathode electrode and the anode electrode are in contact with the electrolytic cell. The bottom of the cell is completely in contact, and the electrolytic cell is divided into an anode chamber and a cathode chamber that are independent of each other. The separation between the anode chamber and the cathode chamber is provided with a proton exchange membrane that allows ions to pass through but isolates hydrogen from passing through the anode region. Due to the structural design of the present invention, the anode chamber and the cathode chamber are isolated and separated from each other, so that the water in the cathode chamber will not be mixed into the anode chamber, thus avoiding the hydrogen generated in the cathode chamber from being mixed into the anode chamber and the neutralization reaction with ozone O3 , thereby reducing the consumption of ozone O3 and improving the production efficiency and content of ozone O3.

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
