Method for producing pure water and device thereof

Abstract

The invention relates to a method for producing purified water and a device thereof; the method includes a production process of the purified water and a refluxing and sterilization treatment processof the purified water. The method is characterized in that the refluxing and sterilization treatment process of the purified water is to regularly filtrate all the purified water stored in an elevatedtank in the production process of purified water via an ultra filter and to reflux to the elevated tank. Compared with the prior art, the invention has the advantages that even a particular drinkingwater machine does not work for a long time, bacteria can not generate in the device to result in secondary pollution of the purified water and that the device and the operation are low in cost.

Description

Technical field: [0001] The present invention relates to a water treatment device. Background technique: [0002] The existing pure water production device that supplies drinking water to the group is mainly composed of a main machine that produces pure water, a pressure tank that ensures the water supply pressure, and drinking water dispensers distributed throughout the group. The drinking water dispenser passes through the pipeline and the pure water outlet of the pressure tank connected together. When in use, the external tap water is processed by the host to become pure water, and then under the action of the pressure tank, it is supplied to the drinking water dispensers in various places of the group for people to drink under a certain pressure. This kind of pure water production device, because pure water flows on the water dispenser everywhere, when individual water dispenser does not work for a long time, will keep part stagnant water in the water dispenser, externa...

AI Technical Summary

Problems solved by technology

This kind of pure water production device, because pure water flows on the water dispenser everywhere, when individual water dispenser does not work for a long time, will keep part stagnant water in the water dispenser, external pollutants (such as bacteria will Enter the water dispenser along the outlet tap of the water dispenser and breed in the still water in the dispenser and spread along the water supply pipeline to contaminate the entire system

For this reason, the inventor has designed the 03267585.2 patented technology to solve the above problems, but the reflux device of this technology needs to be provided with pressure tanks and pressure detectors, and needs to reflux without interruption to sterilize pure water. To increase the cost of equipment, and increase the operating cost of the device
