Reverse osmosis system capable of continuously operating and continuously chemically cleaning

Abstract

The invention discloses a reverse osmosis system capable of continuously operating and continuously chemically cleaning. The system comprises a purification system and a cleaning system, the purification system comprises at least two groups of reverse osmosis assemblies, which are arranged in parallel; and the cleaning system comprises a plurality of branch cleaning assemblies arranged in parallel. The branch cleaning assemblies and the reverse osmosis assemblies are arranged in one-to-one correspondence; at least two reverse osmosis assemblies are arranged in parallel, when part of the reverse osmosis assemblies are polluted, the reverse osmosis assemblies can be seamlessly switched to other reverse osmosis assemblies to purify produced water, at the moment, the polluted reverse osmosis assemblies can be cleaned, it is guaranteed that the purification system continuously outputs purified water, and the water use requirements of production enterprises are met. Due to the fact that pollutants on the reverse osmosis surface can be flushed regularly, shutdown of the system is avoided, operation of the whole system is not affected, the chemical cleaning period of reverse osmosis is prolonged, the frequency of chemical cleaning of reverse osmosis is reduced, and the service life of membrane elements in the reverse osmosis system is prolonged.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a reverse osmosis system with continuous operation and uninterrupted chemical cleaning. Background technique [0002] The reverse osmosis system uses a selective permeable membrane as the separation medium. When there is a driving force on both sides of the membrane, the components of the raw material can pass through the selective membrane to separate, purify and concentrate the raw liquid. Since the membrane pore size of the reverse osmosis membrane is very small, it can effectively remove dissolved salts, bacteria, colloids, microorganisms, organic matter, etc. in water. After the reverse osmosis system has been in normal operation for a period of time, the reverse osmosis membrane elements will be polluted by suspended substances or insoluble substances in the feed water, which will reduce the membrane performance. At this time, the reverse osmosis system needs to be ...

AI Technical Summary

Problems solved by technology

After the reverse osmosis system has been in normal operation for a period of time, the reverse osmosis membrane elements will be polluted by suspended substances or insoluble substances in the feed water, which will reduce the membrane performance. At this time, the reverse osmosis system needs to be physically flushed or chemically cleaned to recover. The performance of the membrane element, but in the actual cleaning process, frequent cleaning will cause the production work of the enterprise to be unable to continue, affecting the production progress of the enterprise
