| 中文摘要: |
| 植物油加工企业的节能降耗是维持其持续发展的重要保证。在原有的400 t/d浸出生产线基础上，将一蒸、二蒸的溶剂蒸气出口与蒸发冷凝器之间增加风冷换热器，充分利用其蒸发器出来的二次溶剂蒸气所含的热量给干空气加热，通过传质、传热降低DC湿粕中的水分及温度，既减少了蒸发二次溶剂蒸气冷凝所需的冷却水用量，又省去原有冷凝回水加热热风的热量，有效降低了植物油厂产品加工吨料成本。 |
| 英文摘要: |
| The energy conservation and consumption reduction of vegetable oil processing enterprises is an important guarantee for maintaining their sustainable development. Based on the existing leaching production line of 400 t/d, the air-cooled heater was assembled between the solvent vapor outlet of the first and second evaporators and the evaporative condenser. The heat contained in the secondary solvent vapor from the evaporator was used to heat the dry air and reduce the moisture and temperature in the DC wetness through mass transfer and heat transfer, which could reduce the cooling water required for the evaporation of the secondary solvent vapor and eliminate the heat of the original condensed return water to heat the hot air. So, the cost of processing tons of vegetable oil plant products could be effectively reduced. |
