The invention relates to an adjustable ozone electrolysis generator assembly. The invention adopts flexible and deformable materials to prepare the anode catalyst membrane, PEM membrane, cathode catalyst membrane and cathode water bag, and integrates the anode catalyst membrane, PEM membrane, cathode catalyst membrane and cathode water bag into an integrated packaging preparation, the spiral electrode The anode catalyst membrane plate, PEM membrane, cathode catalyst membrane plate and cathode water bag in the assembly can be elastically deformed synchronously, and the spiral electrode assembly is spirally coiled in a cylindrical anode water tank to form a cylinder, and a screw loosening control device is also set , the spiral electrode assembly is tightly wound on the vertical shaft in the initial state, which itself has a unwinding stress and a tendency to unwind, and the spiral electrode assembly can be uncoiled or uncoiled under the action of its own stress through the uncoiling control device. A part is tightened so that the contact area for the electrolytic reaction increases or decreases, thereby realizing the adjustment of the electrolysis rate during the ozone preparation process.

A production process of alkali, the steps are as follows: a. Secondary refined brine enters the anode chamber of the electrolytic cell through heat exchanger preheating. When the current reaches 5KA, acid is started to be added to the anode chamber. b. The chlorine gas produced by electrolysis passes through the heat exchanger to preheat the secondary refined brine, so that the temperature of the secondary refined brine reaches 55°C. c. Part of the 32±0.5% concentration of alkali discharged from the cathode chamber is mixed with an appropriate amount of pure water to make a 30±0.5% concentration of alkali into the cathode chamber, where hydrogen is electrolyzed in the cathode chamber. d. The temperature control of the electrolytic cell in the whole electrolytic reaction process is adjusted and controlled at 85-87° C. through the catholyte cooler. e. When the concentration of the electrode catholyte solution reaches 32±0.5%, it will be discharged from the cathode chamber. After passing through the catholyte cooler, part of it will be reused in the cathode chamber, and part will be output to the storage tank. The invention reduces the waste of energy, facilitates the rapid discharge of the generated gas, and improves the productivity of the alkali and the conductivity of the solution.
