中文摘要:
      对浸出油厂二蒸产生的二次蒸汽热能、汽提毛油的热能利用进行了研究。通过加装溴化锂制冷机,将溴化锂制冷机出来的75 ℃循环热水与二蒸产生的二次蒸汽和汽提毛油通过换热器制成95 ℃的热水,用于溴化锂制冷机吸热系统。从溴化锂制冷机出来的7 ℃的冷冻水用于给尾气和石蜡油降温,之后升温到12 ℃再回到溴化锂制冷机制冷系统中进行循环。通过使用溴化锂制冷机,2 500 t/d大豆加工厂的溶耗下降了0.13 kg/t(以大豆质量计),同时降低了冷凝系统循环水的热负荷1 172 979.04 kJ/h,对浸出油厂的生产稳定和经济效益提高有重要的意义。
英文摘要:
      The utilization of the thermal energy of the secondary steam produced by the secondary evaporation and the thermal energy of the stripped crude oil was studied. By installing a lithium bromide refrigerator, the 75 ℃ cycling hot water from the lithium bromide refrigerator was heated to 95 ℃ by the thermal energy of the secondary steam and the stripped crude oil through heat exchanger for heat absorption system of the lithium bromide refrigeration. The 7 ℃ frozen water form the lithium bromide refrigerator was used to cool the exhaust gas and paraffin oil, and then the forzen water with 12 ℃ was returned to the refrigeration system of the lithium bromide refrigerator for recycling. Through the use of lithium bromide refrigerator, the solvent consumption for the 2 500 t/d soybean processing plant was reduced by 0.13 kg/t(on the basis of soybean mass), and the heat load of the condensation system was reduced by 1 172 979.04 kJ/h. The design was of great significance to the stability of production and the improvement of economic benefits of oil leaching plants.
