Problems solved by technology

[0005] Increase the operating voltage of the single slot of the generator, which will eventually affect the operating life of the generator. When the operating voltage of the single slot rises above 5 volts, the generator will be damaged and unable to operate
Metal ions (Me n+ ) pollutes the pure water in the cathode water tank at the same time, affecting its recycling

Embodiment Construction

[0032] as attached figure 1 Shown, a kind of proton exchange membrane type water electrolysis ozone / oxygen generator with self-purification function, comprises pure water tank, ozone / oxygen generator, anode water tank, cathode water tank, the anode of described ozone / oxygen generator chamber and the anode water tank form a loop, the cathode chamber of the ozone / oxygen generator forms a loop with the cathode water tank, and the lower end of the cathode water tank communicates with the pure water tank through a return line to recover the return water from the cathode water tank. The pure water tank communicates with the anode water tank through a diaphragm pump, a two-way solenoid valve and a conductivity sensor to supply water to the anode water tank; a cation exchanger is connected in series in the loop between the cathode chamber and the cathode water tank.

[0033] The ion exchanger is filled with ion exchange resin, the water outlet of the ion exchanger is connected to the...

Abstract

The invention belongs to the technical field of electro-chemicals, and relates to a proton exchange membrane water electrolysis ozone / oxygen generation device with a self-purifying function. An ion exchanger is serially connected in a cathode chamber and cathode water tank circulating loop; ion exchange resins are filled in a pure water tank for further purifying reflux water of a cathode water tank and fed raw material water; and the purified water is fed to the cathode water tank. The device can effectively exchange metal ions migrated to the cathode chamber through a proton exchange membrane and fed in the water of the cathode water tank by the cathode chamber, reduces the electric conductivity of the water to reduce the working voltage of an electrolysis tank, and largely prolongs the generator operation life.

Description

technical field [0001] The invention belongs to the technical field of electrochemistry and relates to a proton exchange membrane water electrolysis ozone / oxygen generator with internal self-purification function. Background technique [0002] The proton exchange membrane type water electrolysis type ozone generator and the proton exchange membrane type water electrolysis type oxygen generator have the same structure, but the catalyst used in the generator is different. Both use pure water as the raw material. Under the action of low-voltage direct current, high-concentration and high-purity ozone / oxygen can be produced in the anode area, and high-purity hydrogen can be produced in the cathode area without producing nitrogen oxides (NOx ), the application prospect is very broad. [0003] Existing electrolytic ozone / oxygen generators, such as Chinese patent ZL201420547893.7 disclose a water electrolysis ozone generator, and Chinese patent ZL201520619763.4 discloses a proton ...
