Abstract

The invention provides an impregnation alkali blending automatic control system in production of short fiber stock solution viscose. The conventional automatic control system is improved and optimized, and a redundant process control system is constructed by redundant process control software, so that the impregnation alkali blending automatic control system in the production of the short fiber stock solution viscose is established. The control system controls the addition amount of an impregnation alkali raw material, performs comparative analysis on set values of the control system to control the flow rate of each medium, and accurately blends impregnation alkali at required concentration, so that the quality of the subsequent impregnation process and the quality of alkaline fibers obtained by the impregnation process are ensured.

Description

technical field [0001] The invention relates to a DCS automatic control system, more specifically, the invention relates to an automatic control system for impregnating alkali preparation in the production of short fiber stock solution viscose. It belongs to the field of man-made fibers. Background technique [0002] Automatic control refers to the use of external equipment or devices to make a certain working state or parameter of a machine, equipment or production process automatically operate according to a predetermined law without direct participation of humans. Automatic control is relative to the concept of manual control, which refers to the use of control devices to make the controlled object or process automatically run according to the predetermined law without the participation of anyone. [0003] The research of automatic control technology is beneficial to liberate human beings from complicated, dangerous and cumbersome working environment and greatly improve ...
