Abstract

The invention discloses a polyvinyl chloride cleaning closed loop preparation system and method. The polyvinyl chloride cleaning closed loop preparation system comprises a chlorine absorption device, a caustic soda device, a magnesium hydroxide device, a magnesium oxide device, a calcium carbide device, an acetylene device, a VCM (Vinyl Chloride Monomer) device, a PVC (Polyvinyl Chloride) device, a C-PVC (Chlorinated Polyvinyl Chloride) device, an E-PVC (Emulsion Polyvinyl Chloride) device and a cement device, wherein the chlorine absorption device, the caustic soda device, the magnesium hydroxide device and the magnesium oxide device are connected together sequentially, a product of a front device is a raw material of a next device; the calcium carbide device, the acetylene device, the VCM device, the PVC device, the C-PVC device and the E-PVC device are also connected together sequentially, a product of a front device is a raw material of a next device; and calcium carbide slag produced by the acetylene device can be recycled as a raw material used for producing cement. With the adoption of the system and the method, polyvinyl chloride cleaning closed loop preparation of resource, production, product, consumption, waste recycling, production, product and consumption is realized, thus driving comprehensive development of multiple resources such as chloride, sodium, coal, limestone and the like, and constructing an integral industry chain of circular economy.

Description

technical field [0001] The invention belongs to the field of resource comprehensive utilization of chemical products, and in particular relates to a resource comprehensive utilization production system and method of a polyvinyl chloride integrated project. Background technique [0002] Polyvinyl chloride is one of the bulk basic chemical raw materials. It occupies a considerable proportion in plastic processing and plays an important role in the national economy. In particular, the policy orientation of "replacing wood with plastic" and "replacing steel with plastic" in the building materials industry has promoted my country's strong demand for PVC. At present, polyvinyl chloride has been widely used in industry, transportation, construction, packaging, electronics, medical and health industries. As the largest organic chlorine-consuming product in the chlor-alkali industry, polyvinyl chloride resin plays an extremely important role in the development of the chlor-alkali in...
