High purity water device for clinical laboratory

Abstract

The invention discloses a high purity water device for a clinical laboratory. The high purity water device comprises a pretreatment unit, wherein the pretreatment unit comprises a mesh filter and an integrated pretreatment column, which are connected with each other; an advanced treatment unit comprises a high pressure pump, a reverse osmosis assembly and a conductivity meter, which are sequentially connected with one another, and the high pressure pump is connected with the integrated pretreatment column; a precision treatment unit comprises an ultraviolet sterilizer, an integrated purifying column, a conductivity meter and a hyperfiltration membrane assembly, and the ultraviolet sterilizer is connected with the conductivity meter; an emergency bypass comprises a ball valve, one end of the ball valve is connected with the integrated pretreatment column, and the other end of the ball valve is connected with the integrated purifying column; and the high pressure pump, the conductivity instrument, the ultraviolet sterilizer and a resistance meter are electrically connected with a measurement and control integrated high-integration intelligent system. The high purity water device is simple in structure, the pollution is avoided, and the water purity is improved.

Description

technical field [0001] The invention relates to a pure water device, in particular to a high-purity water device for laboratory. Background technique [0002] At present, pure water, high-purity water, and ultra-pure water are one of the indispensable and very important basic raw materials of modern industry, and have a very wide range of uses in the fields of electronics, electricity, chemistry, medicine, biology, and information; for medical institutions, especially It is a variety of laboratory departments. Due to the large demand for pure water and high water quality requirements, it is especially necessary for an integrated intelligent device that can use tap water or similar water sources as raw water to facilitate the preparation of high-purity water. [0003] In the existing technology, the processes used in the preparation of pure water mainly include: reverse osmosis + ion exchange, two-stage reverse osmosis process, ion exchange process, etc. The water prepared b...

AI Technical Summary

Problems solved by technology

The water prepared by the ion exchange process has high purity and good stability of effluent water quality, but the process is complicated, and a large amount of acid and alkali are consumed in the system regeneration process, which causes great pollution to the environment; the secondary reverse osmosis process is simple and the effluent water quality Good stability, no need for acid-base regeneration, continuous operation and easy membrane cleaning and maintenance, but there are technical problems such as low desalination rate of the secondary system, high effluent conductivity, and low water purity; and in these processes, once the equipment appears Malfunction, which can lead to the defect that pure water cannot be prepared
