年产5万吨熔喷布生产工艺设计

北京理工大学珠海学院 2020 届本科生毕业设计年产 5 万吨熔喷布的生产工艺设计摘 要2020 年新冠疫情之下，熔喷布的短缺为人们敲响警钟，提高产量满足市场需要称为当下紧迫问题。本设计通过科学合理规划设计出一条年产 5 万吨熔喷布的生产工艺流程，并进行了相关工艺计算。计算出实际年产量为 50010285.6kg，采用的加热方式主要为电加热，输入总能量为 1877332.79kJ/h。对车间进行了合理化布局，满足生产需要。采用的主体设备为熔喷模头，三废处理采用活性炭吸附等方法，处理效果达标。最后对成本进行核算，年利润为 122418.051 万元。本设计数据为熔喷布的工业化生产提供了重要的数据参考。本设计首先进行了生产工艺设计，本设计首先进行了生产工艺设计，对熔喷布的生产工艺进行了一定调整，然后通过物料衡算、热量衡算等工作，得到了能够满足目标产量的生产线。本设计的关键是对原料 PP 进行热处理，同时使用一些助剂避免产品品质的损失。此外，为了达到设计目标--年产 5 万吨熔喷布，需要定制加长款熔喷模头组件，通过计算与合理布局设计，需要 9 条生产线才能完成任务。关键词：熔喷法；非织造布；高产量；工厂设计北京理工大学珠海学院 2020 届本科生毕业设计Annual production process design of 50,000 tons of melt-spraying clothAbstractUnder the covid-19 outbreak in 2020, the shortage of melt-spraying cloth has sounded the alarm for people, and it is an urgent problem to increase production to meet the market demand. The design of a scientific and reasonable planning and design of an annual output of 50,000 tons of melt-spraying cloth production process, and the relevant process calculation. The actual annual output was calculated to be 50010285.6kg. The heating method was mainly electric heating, and the total energy input was 1877332.79kJ/h. The workshop was rationalized to meet the production needs. The main equipment used is the melting spray die head, the three waste treatment methods such as activated carbon adsorption, the treatment effect is up to standard. Finally, the annual profit is 122.48...
