Abstract
Description
Technical Field
[0001] The present application relates to the technical field of water backflow prevention devices, and in particular to a water backflow prevention device for an ozone generator in a pure water station. Background Art
[0002] Ozone water can be produced by passing it into water. When the concentration of ozone water is greater than 5ppm, it has a super strong bactericidal ability. It is widely used in the food processing industry, and its main function is to sterilize and disinfect food. Because the pure water station has a high pressure when producing water, and the simple one-way valve originally provided by the factory is rough, when it is used for too long or the flow is insufficient, it is very easy to cause water to flow to the ozone generator. The working output voltage of the ozone generator is about 3000 volts. The backflow of water can easily damage the equipment or cause serious accidents, resulting in economic losses. Therefore, an anti-backflow device is connected to the output end of the ozone generator to improve the safety of the equipment when it is in use.
[0003] The existing anti-backflow device generally uses an anti-backflow pipe to prevent water backflow, that is, the backflow water must flow into the anti-backflow tank before entering the generator pipe. The anti-backflow tank uses the principle that water is heavier than ozone, and will discharge the water below through the pipe, thereby effectively preventing water from flowing into the generator and damaging the normal operation of the equipment. However, this structural form is too simple to prevent the backflow of water vapor. In addition, due to the presence of the drain pipe, when ozone is negatively adsorbed and transported by the gas-water mixing device, the pressure is easily changed due to the branching of the passage, which causes the ozone content to fluctuate. Therefore, in view of the above problems, an anti-backflow device for the ozone machine of a pure water station is proposed. Utility Model Content
