生产硬质纤维板(湿法),通常采用挤水、干燥、塑化三段加压成型流程,热压机在干燥过程中,所排放出的大量冷凝水,过去一般采用疏水器回送到锅炉蓄水池,虽能回收一部分热量,但大部分热能白白浪费了。宁波木材厂为进一步提高纤维板生产过稈中热能利用率,78年开始研制凝结水回收 The production of hard fiberboard (wet method) usually uses a three-stage pressurization molding process of squeezing, drying, and plasticizing. During the drying process of the hot press, a large amount of condensed water is discharged. In the past, steam traps were generally sent back to the boiler. Although the pool can recover some of the heat, most of the heat is wasted. In order to further improve the utilization of heat energy in fiber stalk production, the Ningbo Timber Factory began to develop condensate recovery in 78 years.
