中文摘要:
      以2 500 t/d大豆加工厂为例,对浸出车间汽提塔二次蒸汽热能利用进行了分析。通过增加200 m2的换热器,将汽提塔二次蒸汽与一蒸后的混合油进行换热,可将混合油的温度由55 ℃提升至62 ℃。经计算,可节省蒸汽1.98 kg/t,可减少冷凝系统循环水热负荷491 952.71 kJ/h,同时使蒸发系统的真空系统更加稳定,对提高油脂加工厂的生产稳定和经济效益有重要的意义。
英文摘要:
      Taking the 2 500 t/d soybean plant as an example, the utilization of the secondary steam thermal energy in the stripper in leaching sector was studied. By adding 200 m2 heat exchanger, the heat exchange between the secondary steam in the stripper and the miscella oil after first evaporator was designed to increase the temperature of miscella oil from 55 ℃ to 62 ℃. It could save steam 1.98 kg/t, reduce heat load 491 952.71 kJ/h. At the same time, the vacuum of the evaporation system was more stable, which was of great significance to the production stability and economic benefits of the oil plant.
