Embodiment 1

[0081] Such as figure 1 As shown, the present embodiment provides a joint production system of polyvinyl chloride resin, which includes a chlorine gas generating device 10, an ethylene production device 13, an ethylene method for producing polyvinyl chloride device 14, an acetylene method for producing polyvinyl chloride device 15, a polypropylene Production device 16.

[0082] Described chlorine generating device 10 comprises electrolytic potassium chloride device 11 and electrolytic magnesium chloride device 12; Connection; said electrolytic magnesium chloride device 12 is connected with said ethylene method production of PVC device 14.

[0083] The ethylene production unit 13 , the ethylene-based PVC production unit 14 , and the acetylene-based PVC production unit 15 are sequentially connected, and the ethylene production unit 13 is also connected to the polypropylene production unit 16 .

[0084] Such as figure 2 Shown, the joint production method of described polyviny...

Embodiment 2

[0131] PVC resin was prepared according to the steps in Example 1, but chlorine was only provided by the electrolytic potassium chloride device 11.

Embodiment 3

[0133] The PVC resin is prepared according to the steps in Example 1, but the production scale of the production of PVC device 15 by the acetylene method is determined according to the scale of the hydrogen chloride produced by the PVC device 14 by the ethylene method, that is, the production of the PVC device 15 by the acetylene method The raw material hydrogen chloride is only provided by the polyvinyl chloride production unit 14 by the ethylene method.

Abstract

The invention discloses a combined production system of polyvinyl chloride resin. The system comprises a chlorine generating device, an ethylene generating device, an ethylene method polyvinyl chloride producing device and an acetylene method polyvinyl chloride producing device. The chlorine generating device and the ethylene generating device are separately connected to the ethylene method polyvinyl chloride producing device, and chlorine produced by the chlorine generating device and ethylene produced by the ethylene generating device are supplied to the ethylene method polyvinyl chloride producing device; the ethylene method polyvinyl chloride producing device is connected to the acetylene method polyvinyl chloride producing device, and acetylene produced by calcium carbide and water and a byproduct hydrogen chloride produced by the ethylene method polyvinyl chloride producing device are supplied to the acetylene method polyvinyl chloride producing device. The invention also provides a combined production method of polyvinyl chloride resin and removes the probability of explosion of hydrogen chloride, and the prepared polyvinyl chloride resin is excellent in quality, extremely competitive and environment-friendly and economical in production process.

Description

technical field [0001] The invention relates to the technical field of resource comprehensive utilization of chemical products, in particular to a polyvinyl chloride resin joint production system and method. Background technique [0002] Polyvinyl Chloride (PVC for short) 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 preparation method of PVC resin, vinyl ...
