Ozone water concentration stabilization constant voltage system of beverage-packaging production line

The invention relates to the technical field of beverage-packaging production line sterilization, in particular to an ozone water concentration stabilization constant voltage system of a beverage-packaging production line. At present, when the beverage-packaging production line stops working, an ozonator does not work and ozone water concentration in pipelines decreases; after the beverage-packaging production line is started, the concentration of the ozone water entering a washer cannot increase to the sterilization concentration instantly, and accordingly the sterilization for liquid beverage bottles is not thorough. The ozone water concentration stabilization constant voltage system is composed of a softened water supply system, an ozone water mixing system and an ozone water constant voltage constant current system. A softened water tank is connected with a water pump, an outlet of the water pump is connected with an inlet of a filter vat, and an outlet of the filter vat is connected with a four-way valve disposed at the bottom of an ozone water blending tank. The high-pressure water pump is connected with the four-way valve disposed at the bottom of the ozone water blending tank, and the outlet end of the high-pressure water pump is connected with a steam water mixing system. An ozonator is connected onto a pipeline through a jet device, and the high-pressure water pump and the steam water mixing system are connected onto the pipeline, too. The ozone water blending tank is connected with the ozone water constant voltage constant current system. The ozone water constant voltage constant current system is also connected with the beverage-packaging production line and the softened water tank.
