Impregnation automatic control system in production of short fiber stock solution viscose

Abstract

The invention provides an impregnation 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 automatic control system in the production of the short fiber stock solution viscose is established. The concentration of pulp is controlled by controlling the feeding speed and addition amount of the pulp and the addition amount of impregnation alkali; a feeding system comprises a pulp feeder and an impregnation alkali feeding pipe which are provided with devices for controlling the feeding amount of the pulp and the impregnation alkali; and the concentration of the pulp has been adjusted during feeding, so that the influence of other interference factors in the subsequent impregnation process is greatly reduced.

Description

technical field [0001] The present invention relates to a DCS automatic control system, more specifically, the present invention relates to a dipping automatic control system in the production of short fiber raw liquid 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 the control effic...
