Large-capacity integrated pure water supply system for laboratories

Abstract

The invention discloses a large-capacity integrated pure water supply system for a laboratory. The system comprises a pre-treatment unit, and the like. An original water pump, an automatic active carbon filter, a front filtering assembly, and a micro-filtration membrane assembly are sequentially connected. A pressure detecting device, and the like are connected between the original water pump and an intelligent programmable control system. An advanced treatment unit comprises a high pressure pump, a reverse osmosis membrane assembly, a flow detecting device, and a second flowmeter, which are connected in sequence. The high pressure pump is connected to the micro-filtration membrane assembly. A one-key disinfection unit is internally provided with a medicine feeding box, which is connected to the reverse osmosis membrane assembly. A fine treatment unit comprises a third flowmeter, an electrodeionization module, a resistivity meter, and a cone-base water tank, which are connected in sequence, wherein the third flowmeter is connected to the second flowmeter; and the cone-base water tank is provided with an air filter and an immersed UV bactericidal lamp and is connected to a water supply pump. According to the invention, the problem of secondary pollution of water can be effectively avoided; automatic filtering and washing can be carried out according to set time; and the working strength is reduced.

Description

technical field [0001] The invention relates to a water supply system, in particular to a large-capacity integrated pure water supply system for laboratories. Background technique [0002] At present, pure water and ultrapure water are indispensable and one of the very important basic raw materials for modern industry, and have a very wide range of uses in the fields of electronics, electricity, chemistry, medicine, biology, and information; Various laboratories, due to the large demand for pure water, especially need an integrated equipment that can use tap water or similar water sources as raw water to facilitate the preparation of pure water and ultrapure water with a small footprint. [0003] In the prior art, the processes used in the preparation of pure water mainly include: reverse osmosis + ion exchange, reverse osmosis + electrodeionization, two-stage reverse osmosis process, ion exchange process, etc.; the purity of water prepared by ion exchange process is high, ...
