On-line control system and method for waste viscose liquid

Abstract

The invention relates to an on-line control system and method for waste viscose liquid. The on-line control system comprises a master controller, a centrifuge, a transfer chute, a blending tank, a resin tower and a bipolar membrane device, wherein a rotation speed signal from the master controller is received by the centrifuge; an air-operated automatic regulating valve A and a conductivity meterA are mounted on the transfer chute; the conductivity meter A is used for sending a concentration signal to the master controller; a temperature sensor A, an air-operated automatic regulating valve B,an air-operated automatic regulating valve C, a conductivity meter B, a ph meter A and a plate type heat exchanger A are mounted in the blending tank; the temperature sensor A is used for sending a temperature signal to the master controller. According to the on-line control system disclosed by the invention, a detection signal is remotely transmitted to the master controller through electricity,and intelligentized control is performed on a whole production line according to practical situations by the master controller, so that the treatment time of waste liquid is prolonged, and the treatment efficiency of the waste liquid is improved.

Description

technical field

[0001] The invention belongs to the technical field of viscose waste liquid treatment, and in particular relates to an online control system and method for viscose waste liquid. Background technique

[0002] Viscose fiber is a chemical fiber processed by chemical and mechanical methods using polymer materials such as wood pulp and cotton pulp containing natural cellulose. Viscose fiber is the kind of chemical fiber that is closest to the performance of natural fiber clothing. It has the characteristics of soft hand feeling, moisture absorption and breathability, elegant hanging, bright dyeing, antistatic and easy textile processing. It is a regenerated fiber derived from nature and superior to nature. Vegan fiber is one of the important raw materials for the textile industry. At present, there are about 40 viscose fiber enterprises in my country. In addition to producing ordinary viscose fiber (filament, short fiber) and strong yarn, high wet modulus fibers ...
