Abstract
本发明公开了一种用含油脂废水生产皂基的方法，所述含油脂废水是按照以下方法加工成皂基的：(1)将含有少量油脂的废水引入室外沉淀池塘，使其在阳光下自然酸败；(2)从池塘水面上捞取酸败后的油脂得皂化原料；(3)将皂化原料与火碱进行皂化反应，并分离出皂基，该方法可以利用含有少量油脂的废水生产出皂基，且生产成本低，环保。
Description
技术领域
本发明涉及一种皂基的生产方法，尤其是一种利用含少量油脂的废水生产皂基的方法。
背景技术
骨粉生产过程中需定期清洗压力罐、输送机、储油容器等，会产生大量的废水，这种废水中油脂含量通常不超过5％，直接用来生产皂基会因为其中油脂含量少，需要进行反复浓缩处理，生产成本高，而直接排放会污染环境，因此，通常要经过净化处理才能排放，不但增加了生产成本而且也浪费了资源。
发明内容
发明要解决的技术问题：提供一种用含油脂废水生产皂基的方法，该方法可以利用含有少量油脂的废水生产出皂基，且生产成本低，环保。
解决技术问题所采取的技术方案：一种用含油脂废水生产皂基的方法，所述含油脂废水是按照以下方法加工成皂基的：
(1)将含有少量油脂的废水引入室外沉淀池塘，使其在阳光下自然酸败；
(2)从池塘水面上捞取酸败后的油脂得皂化原料；
(3)将皂化原料与火碱进行皂化反应，并分离出皂基。
作为本发明的改进：在步骤(1)中，酸败过程为5-10天。
有益效果：本发明中由于采用了先将含有少量油脂的废水引入室外沉淀池塘，使其在阳光下自然酸败，再从池塘水面上捞取酸败后的油脂作为皂化原料，最后将皂化原料与火碱进行皂化反应，并分离出皂基的生产工艺，使得原本没有利用价值、且要付出环保成本的废水能够生产出皂基；在本发明中使含少量油脂(低于5％)的废水在池塘中自然酸败，使污水中含的少量难于分离的油脂在酸败后浮于水面上，便于收集，较采用加热蒸发浓缩的收集方式节约了大量的成本，使这种油脂含量少的废水具备了利用价值，并且由于油脂酸败的过程中在生物、酶、空气中的氧的作用下已经发生部分水解，因此，在皂化反应时更容易水解成皂基，加快了皂化反应的过程，较直接用油脂进行皂化降低了成本。
具体实施方式
下面对本发明的技术方案作进一步详细说明：
一种皂基的生产方法，所述皂基是按照以下方法生产的：
(1)将骨粉生产过程中清洗压力罐、输送机、储油容器等产生的含有少量油脂(油脂含量小于5％)的废水，直接引入室外沉淀池塘，使其在阳光下经生物、酶、空气中的氧的作用发生自然酸败，酸败过程为5-10天，酸败后的油脂会漂浮在水面上；
(2)从池塘水面上捞取酸败后的油脂得皂化原料；
(3)将皂化原料送到皂化车间，采用普通的皂化技术使皂化原料与火碱进行皂化反应，并分离出皂基。
Claims (2)
1.一种用含油脂废水生产皂基的方法，其特征是：所述含油脂废水是按照以下方法加工成皂基的：
(1)将含有少量油脂的废水引入室外沉淀池塘，使其在阳光下自然酸败；
(2)从池塘水面上捞取酸败后的油脂得皂化原料；
(3)将皂化原料与火碱进行皂化反应，并分离出皂基。
2.根据权利要求1所述的一种用含油脂废水生产皂基的方法，其特征是：在步骤(1)中，酸败过程为5-10天。
