Abstract

The invention discloses a control method and system suitable for treating viscose waste liquid through a bipolar membrane in a spinning system, and belongs to the field of viscose fiber production. The control system is arranged in a viscose fiber production line and comprises a bipolar membrane controller for performing electrodialysis treatment on the viscose waste liquid, wherein the bipolar membrane controller is connected with a human-computer interface through a data input interface, the bipolar membrane controller is connected with a data acquisition unit through a data feedback interface, and the bipolar membrane controller is connected with an execution unit through a data output interface. Through the arrangement of the control system and the control method for treating the viscose waste liquid by the bipolar membrane, the automation of treating the viscose waste liquid in a spinning process by bipolar membrane electrodialysis is realized, the labor intensity is reduced, and the stability, the controllability and the traceability of viscose waste liquid treatment are ensured; and meanwhile, the viscose waste liquid is effectively treated, so that the waste liquid is recycled, and the environmental protection pressure is reduced.

Description

technical field [0001] The invention relates to a control system suitable for a spinning system, in particular to a control method and system for treating viscose waste liquid with a bipolar membrane suitable for a spinning system, and belongs to the field of viscose fiber production. Background technique [0002] Viscose fiber is a chemical fiber made of polymer materials containing natural cellulose, such as wood pulp and cotton pulp, through chemical and mechanical processing. It is the most similar type of chemical fiber to natural fiber clothing. Breathable, elegant hanging, bright dyeing, antistatic and easy for textile processing, etc., it is derived from natural and superior to natural regenerated cellulose fiber, and is one of the important raw materials for the textile industry. The production and spinning of viscose fiber requires a large amount of chemical raw materials, which leads to a large amount of harmful waste liquid. The waste liquid contains sulfuric aci...
