Intelligent pure water/ultra-pure water preparing system and automatic control method thereof

Abstract

The present invention provides an intelligent pure water / ultra-pure water preparing system and an automatic control method thereof, which comprises the steps of pretreating, medicine adding, film filtering, sterilizing and disinfecting to the water. The invention is characterized in that: the full flow from the raw water inlet to the pure water product is designed with modules, and the whole process flow is composed of a pretreating module, a constant temperature module, an anti-penetration primary desalting module, an EDI advanced desalting module, a physical sterilizing module, a TOC decomposing module, a degassing module, a temperature regulating module and a water-quality fine-processing module which are sequentially connected in series; the operation of each stage of module in the flow adopts a distributed automatic control system, the centralized management and three-stage control of distributed control to the operation condition of each process flow module are realized through PC technology with the field bus. The system of the invention is designed to an integrated device, and the modularized designing of the full flow is designed to a state that the modules can be added ordeleted randomly without affecting the operation of the whole system. The intelligent pure water / ultra-pure water preparing system has high flexibility in the application aspect and has the advantages of compact structure, construction quality increase, shortened construction period, etc.

Description

technical field [0001] The invention relates to a water treatment technology, and in particular discloses an intelligent pure water / ultrapure water production system and an automatic control method thereof, which are applied to the fields of high-purity water in the pharmaceutical industry, pure water industry and electronic industry. Background technique [0002] With the introduction of foreign pure water / ultrapure water equipment in the 1990s and the rapid development of domestic industrial water treatment technology and equipment, advanced pure water / ultrapure water manufacturing process equipment and automation control are widely used in this field , has a great market demand, and almost all industries of the national economy will use pure water or ultrapure water. [0003] The automatic control content of the general pure water / ultrapure water production system includes: automatic start and stop of equipment, automatic cleaning or regeneration of equipment, and automat...
