摘要
松脂是我国丰产的特色林产资源,其主要加工产品松香、松节油等均是重要的林源基础化工原料,然而,虽然国内松脂加工企业众多,近年来相关加工技术却没有太大改进,普遍存在水耗高、损耗大等缺陷。针对上述问题,本研究开发出松脂节水减排绿色加工工艺,通过松脂节水输送、松脂节水溶解、松脂节水净化、中层脂液节水回收以及净制脂液节水蒸馏等技术有效降低了松脂加工的耗水量。通过相关研究及生产示范,云南松/思茅松松脂加工的耗水量为0.759 t/t,马尾松松脂加工的耗水量为0.836 t/t,较现有优质松脂加工企业节水70%以上,中层脂液中机械杂质的去除率超过90%。
Oleoresin is a characteristic high output forestry resource in China and its main processing products such as rosin and turpentine are important forest-based chemical raw materials.However,even there are many rosin production enterprises in our country,the processing technology of oleoresin had almost no improvement in recent years.The water-consumption and the loss of oleoresin in these processes are still very high.To solve these problems,this paper reported a watering-saving and emission-reduction green processing technology for oleoresin.The water consumption was evidently reduced through water-saving oleoresin transportation,oleoresin melting,oleoresin impurity removal,recycling of the middle-layer oleoresin liquid and purified oleoresin distillation technologies.Through relevant research and production demonstrations,the water consumption for the oleoresin process of Pinus yunnanensis/Pinus kesiya was 0.759 ton per ton(oleoresin),and that of Pinus massoniana was 0.836 ton per ton,which was nearly 70%less than the existing high-quality rosin processing enterprises.The removal rate of mechanical impurities in middle-layer oleoresin liquid was over 90%.
