Abstract
一种冷凝式油水分离方法，通过油和水的凝固点不同，在油达到凝固点而水并未达到凝固点的温度范围内，实现油和水的高效油液分离，包括步骤：1)、制作冷凝板；2)、对冷凝板进行降温冷凝，使得冷凝板的温度高于水的凝固点而等于或低于油的凝固点；3)、将冷凝后的冷凝板底面放置并接触在静止后的盛有油液的机箱内的液体上表面，将悬浮在液体表面的油冷凝成油脂并粘附到冷凝板上；4)、用刮油板刮除粘附在冷凝板上的油脂。
Description
本发明涉及油水分离技术领域，具体地说是一种冷凝式油水分离方法。
众所周知，现有的油水分离设备的分离方式大致可分为重力式分离、离心式分离、电分离、吸附分离、气浮分离等，这些油水分离方式均存在各自的实质性缺陷，油水分离时间长、提油效率低、出油纯度低，如重力式分离方式采用沉降池形式，会导致液体流动存在死区，部分液体得不到流动置换，水中有机质会逐渐腐败变臭；气浮分离方式会产生大量臭气；离心式分离方式设备动力部件维护困难，目前只应用于实验室的分析设备等。
另外，上述分离方法分离出的油水由于分离不彻底，导致油品差，储存及再利用困难。
发明内容
本发明的目的在于解决现有技术的不足，提供一种方法简单、油水分离时间短、提油效率高、出油纯度高的冷凝式油水分离方法。
本发明解决其技术问题所采用的技术方案是：
一种冷凝式油水分离方法，其特征在于通过油和水的凝固点不同，在油达到凝固点而水并未达到凝固点的温度范围内，实现油和水的高效油液分离，
本发明冷凝式油水分离方法通过以下步骤得到：
1、制作冷凝板；
2、对冷凝板进行降温冷凝，使得冷凝板的温度高于水的凝固点而等于或低于油的凝固点；
3、将冷凝后的冷凝板底面放置并接触在静止后的盛有油液的机箱内的液体上表面，将悬浮在液体表面的油冷凝成油脂并粘附到冷凝板上；
4、用刮油板刮除粘附在冷凝板上的油脂；
由于油的浮力大于水和杂物而悬浮于液体表面，因此，如此反复重复上述1-4步骤，即可将油水渣分离彻底，显著提高了提油纯度和提油效率。
本发明还包括步骤5：对刮除后的除油槽进行加热，以使油脂加热后形成液体油而快速流入到接油桶中。
本发明所述步骤1冷凝板是由平板和冷板蒸发器构成，所述冷板蒸发器固定在平板上，所述冷板蒸发器与热泵系统连接，所述热泵系统与温控开关连接，所述平板是由导温材 料制成。
本发明所述步骤5除油槽是由槽体和槽体下面的油冷冷凝器构成，所述油冷冷凝器与热泵系统连接。
本发明所述温控开关可以采用PLC控制器，以达到自动控制的作用。
本发明由于采用上述方法，具有结构新颖，提油效率高，出油纯度高等优点。
下面结合附图和实施例对本发明进行说明。
