Description

Technical Field

[0001] This application relates to the field of reverse osmosis membranes, and in particular to an integrated device for removing and replacing medical pure water reverse osmosis membrane elements. Background Technology

[0002] Reverse osmosis membrane elements are a special type of filtration element that effectively removes dissolved salts, heavy metal ions, colloids, bacteria, viruses, and other impurities from water. These elements are typically made of polymers such as cellulose acetate or aromatic polyamide, and have tiny pores that prevent most harmful substances from passing through while allowing water molecules to pass through. Reverse osmosis membrane elements are widely used in seawater desalination, brackish water desalination, boiler feedwater production, industrial pure water preparation, and drinking water production. In the prior art, a reverse osmosis membrane element includes an element body with a raw water inlet and a pure water outlet at both ends, and a concentrate outlet on the side of the element body near the blow water outlet. The element body filters the incoming raw water, and the filtered water is discharged from the pure water outlet, while other filtered substances are discharged from the concentrate outlet.

[0003] Regarding the aforementioned patents, when reverse osmosis membrane elements suffer irreversible damage such as oxidation, back pressure, and mechanical damage, or when their performance naturally declines with age, the reverse osmosis system cannot meet the desalination rate and permeate volume requirements even through online or even offline chemical cleaning. In such cases, the membrane elements need to be replaced. This requires shutting down the entire reverse osmosis membrane system and suspending the supply of pure water. In emergency situations such as hospitals, the suspension of pure water supply can disrupt normal operations and urgently needs improvement. Summary of the Invention

A plurality of raw water insertion tubes connected to the raw water pipe are spaced apart on the sliding plate. Each raw water insertion tube corresponds to a reverse osmosis membrane element on the mounting base. The raw water insertion tube is inserted into the raw water inlet. When the raw water insertion tube is inserted into the raw water inlet of the working unit, it is the working time. When the raw water insertion tube is inserted into the raw water inlet of the standby unit, it is the replacement time.

[0006] By adopting the above technical solution, during use, the raw water inlet of the working unit is inserted into the raw water inlet, allowing the reverse osmosis membrane element to operate normally. When the reverse osmosis membrane element of the working unit reaches the end of its service life after a period of use, the raw water inlet of the spare unit is inserted into the raw water inlet for replacement, allowing for continuous output of pure water and replacement of the reverse osmosis membrane element of the working unit. After replacement, the reverse osmosis membrane element of the working unit is reinserted into the installation chamber, and the raw water inlet is reinserted into the raw water inlet of the working unit to continue the reverse osmosis operation. Multiple working units can be provided, which can greatly reduce the cycle time for replacing reverse osmosis membrane elements and improve the convenience of using the device. This provides a solution that enables the removal and replacement of reverse osmosis membrane elements in pure water equipment in hospitals and pharmaceutical fields without shutting down the system, allowing the entire pure water treatment system to achieve 24-hour uninterrupted water production.
