Technical Field

The invention relates to the technical field of ozone generators, in particular to an ozone generator capable of vaporizing liquid oxygen by utilizing self waste heat.

Background

The existing ozone preparation process flow is that liquid oxygen in a liquid oxygen storage tank is vaporized by a vaporizer, then is input into a tank body of an ozone generator under the pressure regulation of a pressure reducing valve, and generates ozone after passing through an ozone pipe. When the ozone generator works, gaseous oxygen is used as a raw material, and the oxygen is ionized by corona discharge to generate ozone. Can produce a large amount of heats among the ionization process, this just need cool off the generator, in time take away the heat, otherwise the temperature risees and can make ozone output reduce, and too high can make the equipment piece bad. In the process of preparing ozone by the ozone generator, circulating cooling water needs to be introduced into the tank body to cool the tank body, and heat generated by the ozone generator is not well utilized, so that heat waste is caused.

The raw material required by the ozone generator for preparing ozone is oxygen. At present, two methods of PSA pressure swing adsorption oxygen production and liquid oxygen production by fractionating liquid air are industrially obtained. Because liquid oxygen purity is higher than PSA system oxygen (liquid oxygen purity 99.5%, PSA system oxygen purity 90%) and use the equipment fault rate low more stable, so mostly adopt the liquid oxygen mode. The gaseous oxygen required by the ozone generator is formed by vaporizing liquid oxygen, and the vaporization of the liquid oxygen into the gaseous oxygen needs to absorb heat.

In the existing ozone preparation process, oxygen is changed into gas from liquid after a vaporizer absorbs heat. The heating vaporizer consumes energy to heat and vaporize the liquid oxygen. The air temperature type vaporizer heats low-temperature liquid oxygen by utilizing natural convection of air to gasify the low-temperature liquid oxygen, although the heat exchanger is energy-saving, the heat exchanger is particularly sensitive to the ambient temperature, and the problem of incomplete gasification of the liquid oxygen can be caused when the ambient temperature is low. Meanwhile, the use of the liquid oxygen vaporizer increases the cost and occupies a part of the space.
