Full-automatic control system and control method of ultra pure water machine

Abstract

The invention discloses a full-automatic control system and a control method of an ultra pure water machine and relates to a water purification system. Concentrated water which is discharged from a reverse osmosis module is recycled; at the same time a cycle control method of ultra pure water can effectively clean an ultra pure water circulation system through disinfection, the necessary purity degree of the ultra pure water circulation system can be guaranteed, and circulation flow of disinfectants in the system enables the disinfection effect to be obvious and thorough; and accordingly pure circulation environment can be fully guaranteed compared with the traditional ultra pure water circulation systems.

Description

Technical field [0001] The invention relates to a water purification system, in particular to an ultrapure water circulation control system and a control method. Background technique [0002] The existing ultrapure water system uses a PP filter element to remove impurities such as rust, sand, algae, etc., and an activated carbon filter element to absorb and filter residual chlorine, odor, and color in the tap water; the reverse osmosis module can filter out bacteria, Viruses, inorganic salts, pesticides, etc., the existing ultrapure water machine needs to replace the filter element after purifying a certain volume of water, but the existing ultrapure water machine does not have precise and detailed flow monitoring and alarm functions; at the same time, the existing In the ultrapure water manufacturing device, the reverse osmosis module directly discharges wastewater, and the wastewater cannot be recycled, nor can it be monitored for tertiary water and ultrapure water.

Problems solved by technology

[0002] The existing ultrapure water system uses PP filter elements to remove impurities such as rust, sediment, and algae in the water, and uses activated carbon filter elements to absorb and filter residual chlorine, odor, and color in tap water; the reverse osmosis module can filter out bacteria, Viruses, inorganic salts, pesticides, etc., the existing ultrapure water machine needs to replace the filter element after purifying a certain volume of water, but the existing ultrapure water machine does not have accurate and detailed flow monitoring and alarm functions; at the same time, the existing In the ultrapure water manufacturing device, the reverse osmosis module directly discharges the wastewater, which cannot be recycled, nor can it monitor the tertiary water and ultrapure water

[0003] In the existing ultrapure water manufacturing process, only pure ultrapure water production and consumption are performed based on the ultrapure water manufacturing system, which cannot monitor the system to ensure the safe operation of the system. More importantly, in the ultrapure water After the system has been used for a period of time, biofilm will form in the pipeline. If it cannot be cleaned regularly, it will not only affect the quality of ultrapure water but also reduce the service life of the system.
