According to the calculation and can shift production continuously, arrange three shifts a day, 8 hours per shift production strength, design can reach 1100 tons annual output of 400000 tons of polyvinyl chloride (PVC) production workshop.The plant's location according to the characters of natural geography, transportation, water and power supply conditions, construction conditions and workers housing conditions such as optimization of principle.Rectangular workshop to make plant general layout, economical use of land, convenient equipment arrangement, there are more metope provide for the use of natural lighting and ventilation design.This design also fully consider the staff's working environment and work safety, as far as possible to the workshop planning for safe, green.In the process of production, in the case of staff observe workshop operation procedures, required production personnel strictly comply with operation procedures, and often take part in the safety knowledge training, information, work more safety and efficiency.In terms of environmental protection, discharge of waste water and noise has carried on the strict requirements.
According to the design plan descriptions of the task, I successfully completed the PVC polymerization process of process design.Throughout the design process of polyvinyl chloride production process, and its applications have a more comprehensive understanding, it is engaged in the related work to lay the foundation for the future.
Chun-hua xu, an associate professor in the whole design process is put forward many valuable guidance, can make the design more efficient completion, express our heartfelt thanks here.Given the limited knowledge and practical experience, the design is lack, please read the teacher comment.
