Abstract

The invention relates to the control technology field and particularly relates to a DCS redundancy control system for the foodstuff grade terpenes resin production line. The DCS redundancy control system for the foodstuff grade terpenes resin production line comprises a central monitor server, a DCS upper industrial computer, and a PLC module which are connected successively. The PLC module is connected to a temperature transmitter, a double-flange differential pressure transmitter, a throw-in type liquid level transmitter and a pressure transmitter. The DCS redundancy control system for the foodstuff grade terpenes resin production line solves the extra polymer produced through the polymerization process, improves the yield, realizes the effective separation of the high/low polymer and the catalysis residue, solves the problems of the water volume of the hot water supply system and the super high energy consumption materials, solves the explosion caused by the overreaction in the polymerization procedure, solves the no good distillation effect in the toluene distillation process and hard control in the reaction process, guarantees the product distillation effect and improves the product yield rate.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a DCS redundant control system used in a food-grade terpene resin production line. Background technique [0002] Terpene resin is light yellow transparent, brittle solid. It is non-toxic, odorless, radiation-resistant, resistant to dilute acid, dilute alkali, anti-crystallization, and strong electrical insulation. It has good compatibility with various synthetic compounds, easily soluble in benzene, toluene, turpentine, ether and other organic solvents, insoluble in water, formic acid and ethanol, etc. It has a wide range of applications and is widely used in rubber, adhesives, heat-sensitive adhesive tapes, hot-melt coatings, paints, flat inks, packaging, anti-rust oil, chewing gum (food grade) and other industries. [0003] At present, the domestic terpene resin production lines generally have the following production problems: [0004] 1) The enamel polymerization kettle pr...
