A casing type electrolyzed water oxygen generator

Abstract

A casing tube type water electrolysis oxygen production device comprises an oxygen production reactor. According to the oxygen production reactor, a three-layer casing tube is composed of a tube-type solid oxide electrolytic tank, a tube-type solid oxide fuel cell and an insulation sealing tube from inside to outside. A front sealing end board and a rear sealing end board are installed at the two ends of the three-layer casing tube and fixedly connected through screws and nuts. In the use process, 1.2 V to 2.0 V voltage is input between the positive electrode and the negative electrode of the tube-type solid oxide electrolytic tank, a positive electrode reaction is generated on the positive electrode side to consume H2O and produce H2, and a negative electrode reaction is generated on the negative electrode side to produce O2; meanwhile, 0.6 V to 0.9 V voltage is output through the two sides of the tube-type solid oxide fuel cell, an anode reaction is generated on the anode side to consume H2 and produce H2O, a cathode reaction is generated on the cathode side to consume O2 in the air, and generated electric energy is input to the tube-type solid oxide electrolytic tank; and by the adoption of the casing tube oxygen production reactor, the complexity of a system is lowered.

Description

technical field [0001] The invention belongs to the technical field of oxygen production, and in particular relates to a casing type electrolytic water oxygen production device. Background technique [0002] There are three main methods for producing high-purity oxygen: (1) cryogenic method; (2) pressure swing adsorption method; (3) electrolytic water oxygen production method. Among them, the electrolytic water oxygen production method has high stability, low energy consumption, and wide application range of capacity. At present, proton exchange membrane electrolyte is mostly used in oxygen production by electrolysis of water. This kind of electrolyte has low working temperature (<100 ℃) and good portability, but the system efficiency and service life are low. The electrolytic water oxygen production method using solid oxide electrolyte works at 600°C-1000°C without noble metal catalysts, which can reduce costs, improve system efficiency and life, and the system is small...
