Title:
MEMBRANE ELECTRODE ELECTROLYTIC OZONE GENERATOR AND PREPARATION PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/078266
Kind Code:
A1
Abstract:
The present invention provides a membrane electrode electrolytic ozone generator and a preparation process therefor. The membrane electrode electrolytic ozone generator comprises a cation exchange membrane, and a cathode structure and an anode structure respectively provided at two sides of the cation exchange membrane, wherein a sealing ring is provided on a cathode guide-fastening plate; a cathode microporous plate is put into the sealing ring to be tightly attached to the cathode guide-fastening plate; a cathode catalyst is put into the sealing ring to be attached to the cathode microporous plate; the cathode structure, the cation exchange membrane and the anode structure are integrally fastened by means of fastening elements. The cathode catalyst is a cathode catalyst particle layer formed by Ti2O3 particles or Ti2O3 particle and isolate particle mixtures. The material cost of the cathode catalyst of the membrane electrode electrolytic ozone generator is reduced. After the tight pressing with pressure, the contact of the fastened cathode catalyst particle layer and the cation exchange membrane is more uniform. The problem of current distribution non-uniformity of the membrane electrode electrolytic ozone generator is solved. The service life of the membrane electrode electrolytic ozone generator is effectively prolonged.
