AI Technical Summary

Technical Problem

In existing reverse osmosis systems, the pressure coupling imbalance caused by the direct connection between the pretreatment section and the high-pressure pump leads to the degradation of reverse osmosis membrane life and a high system failure rate.

Method used

A transfer tank is introduced between the pretreatment section and the high-pressure pump to form a liquid buffer zone, which can absorb sudden changes in flow rate, provide constant head suction conditions, ensure that the booster pump outputs a stable high-pressure water flow, and build a dynamic buffer center to avoid damage to the reverse osmosis membrane caused by pressure fluctuations.

Benefits of technology

This achieves stabilization of the reverse osmosis membrane's operating pressure range, extends membrane life, improves system reliability and ease of maintenance, and ensures the stable production of high-purity medical water.

Abstract

The utility model relates to medical pure water preparation technical field, concretely relates to a medical purified water reverse osmosis treatment device, and the device forms the buffer hub between pretreatment and reverse osmosis unit through the transfer tank bottom end connection booster pump suction end. The transfer tank absorbs the front water flow pulsation, eliminates flow fluctuation, and provides constant head condition for the booster pump, guarantees the high pressure required by reverse osmosis to establish stably, and the booster pump output water flow to the reverse osmosis filter completes molecular sieve, and the bottom end discharge joint exports pure water, and the radial outside waste joint leads and arranges the concentrated solution, and the filling joint on the top of transfer tank realizes the injection of reagent, and the first cover of reverse osmosis filter top supports the maintenance of membrane, and the structure solves the pressure concussion problem caused by the direct coupling of pretreatment unit and high pressure pump, avoids the mechanical damage of reverse osmosis membrane by wave crest and the risk of wave trough incrustation, prolongs the life of membrane, and the pure waste shunt and detachable structure improve operation reliability and maintenance efficiency.
