求翻译：通过研究在pvc生产过程对HCl合成以及VCM合成中的余热回收利用，对电石法生产pvc中电石炉的改造，以及对pvc厂加强管理以达到节能的目的是什么意思？

Hcl synthesis and the vcm synthesis in waste heat recovery, use the pvc production process by studying the production of calcium carbide process of the transformation of calcium carbide furnace in pvc, pvc factory strengthen management to achieve energy saving

Through the study of the PVC production HCl VCM synthesis, synthetic as well as the residual heat recycling, production of calcium carbide in PVC for calcium carbide furnace of transformation, as well as strengthening the management of the PVC plant to save

Through the research in the pvc production process to in the HCl synthesis as well as the VCM synthesis afterheat recycling use, produces in pvc to the calcium carbide law the carbide furnace transformation, as well as achieves the energy conservation to the pvc factory enhancement management the go

HCl synthesis through the research in the production process of PVC and VCM recovery and utilization of waste heat in the synthesis, modification of carbide PVC production by calcium carbide furnace, as well as for strengthening the management of PVC in order to achieve the goal of energy saving
