Energy Saving Application of Lithium Bromide Absorption Refrigeration Technology in Polyester Production Process

文中介绍了溴化锂吸收式制冷技术的工作原理以及溴化锂制冷机的产品优势,将该技术应用于化纤生产工艺中,可充分利用化纤聚酯生产工艺过程的酯化蒸汽,制取聚酯工艺冷却、喷丝冷却车间等工艺需要的冷水,实现余热利用,节能高效目的。文中结合实际案例对酯化蒸汽采用间接利用与直接利用两种节能方案,通过与传统电驱动制冷机方案对比,采用溴化锂吸收式制冷技术的节能方案收益性明显,投资回收期短,对同行业在节能减排、余热利用等方面具有重要的参考意义。

This paper introduces the working principle of lithium bromide absorption refrigeration technology and the product advantages of lithium bromide refrigerator.Applying this technology to the chemical fiber production process can make full use of the esterification steam in the chemical fiber polyester production process to produce the cold water required by polyester process cooling and spinning cooling workshop,so as to realize the purpose of waste heat utilization,energy saving and high efficiency.Combined with practical cases,two energy-saving schemes of indirect utilization and direct utilization are adopted for esterification steam.Compared with the scheme of traditional electric driven refrigerator,the energy-saving scheme using lithium bromide absorption refrigeration technology has obvious profitability and short investment payback period,which has important reference significance for the same industry in energy conservation,emission reduction and waste heat utilization.
