Polyvinyl chloride joint production system and interlocking control method thereof

Abstract

The invention discloses a polyvinyl chloride joint production system. The polyvinyl chloride joint production system comprises an electrolytic magnesium chloride device, an electrolytic potassium chloride device, a chlorine distribution device, an ethylene-process polyvinyl chloride production device, an acetylene-process polyvinyl chloride production device and an interlocking device, wherein theinterlocking device comprises a plurality of interlocking signal lines arranged among the devices; when a certain device stops, the interlocking device transmits a stopping signal to an up-down stream device connected with the stopped device through the interlocking signals; the up-down stream device determines whether interlocking stopping is executed or not according to the stopping signals. According to the polyvinyl chloride joint production system disclosed by the invention, the production is safer and more reliable by adopting a control way of the interlocking device, and automatic control can be carried out; once failures or accidents occur, manual operations are reduced; the device can stop once interlocking of the system is carried out; relative to manual operation, the lag is reduced, and the safe production is facilitated.

Description

technical field [0001] The invention relates to the technical field of resource comprehensive utilization of chemical products, in particular to a polyvinyl chloride joint production system and an interlocking control method thereof. Background technique [0002] Polyvinyl Chloride (PVC for short) resin is a high molecular compound polymerized by Vinyl Chloride Monomer (VCM for short). PVC resin is a kind of synthetic material that is popular, popular and widely used at present. It has become the second largest general-purpose resin in the world after polyethylene resin, accounting for 29% of the world's total consumption of synthetic resin. . PVC resin is easy to process, and can be processed by molding, lamination, injection molding, extrusion, calendering, blow molding, etc. PVC resin is mainly used to produce plastic soft products such as artificial leather, film, wire sheath, etc. Hard plastic products such as doors, windows, pipes and valves. [0003] In the prepara...
