Novel pure water supplying system

Abstract

The invention discloses a novel pure water supplying system. The system comprises a raw water box, a reverse osmosis membrane treating device, a pure water tank and a concentrated water tank, whereinraw water in the raw water tank is guided to the reverse osmosis membrane treating device to be treated to produce pure water and concentrated water, and the pure water and the concentrated water arecorrespondingly guided to the pure water tank and the concentrated water tank; the reverse osmosis membrane treating device comprises at least one two-stage reverse osmosis membrane treaters; the reverse osmosis membrane treater at each stage comprises a plurality of reverse osmosis membranes which are connected in parallel; a raw water inlet of each reverse osmosis membrane is connected to a mainraw water input pipe through a raw water input branch pipe; a pure water inlet of each reverse osmosis membrane is connected to a main pure water output pipe through a pure water output branch pipe;a concentrated water inlet of each reverse osmosis membrane is connected to a main concentrated water output pipe through a concentrated water output branch pipe; and the reverse osmosis membrane treaters are interconnected in series or in parallel. With the adoption of the system, the pure water yield and utilization rate can be increased; the production demand is met; and the water is saved.

Description

technical field [0001] The invention belongs to the technical field of industrial water supply, and in particular relates to a novel pure water supply system. Background technique [0002] The pure water used in the production of general industrial enterprises is supplied by the enterprise itself. The production of pure water usually adopts reverse osmosis membrane technology. The reverse osmosis membrane technology can filter out impurities and ions in the raw water, and the filtered water is pure water. However, while pure water is produced, concentrated water must be discharged, and concentrated water is often discharged directly. Moreover, the pure water output of the general water supply system is constant. When the amount of pure water required is small, the pure water output of the water supply system will be excessive, resulting in waste of production capacity; and when the amount of pure water required is large, and the pure water index When the requirements are on...

However, while pure water is produced, concentrated water must be discharged, and concentrated water is often discharged directly

Moreover, the pure water output of the general water supply system is constant. When the amount of pure water required is small, the pure water output of the water supply system will be excessive, resulting in waste of production capacity; and when the amount of pure water required is large, and the pure water index When the requirements are only qualified for important indicators, the pure water output of the water supply system will be insufficient to meet the production needs
