乳化柴油微波加热装置
技术领域
本发明涉及一种柴油机使用乳化柴油如乳化水柴油或醇型乳化 水柴油等作燃料并能有效提高其燃油效率的供油装置，属于内燃机领 域。
背景技术
乳化柴油是一种在纯柴油中加入一定比例的水或水和醇等与专 用的乳化剂经充分搅拌混合而成的混合燃料，具有较大的功率，廉价 的成本、能够满足燃油锅炉和轮船等大排量的设有蜗流式燃烧室的柴 油机的用油需要，是一种能节约柴油的节能燃料，但是在使用过程中 我们发现了一些问题，例如：用乳化柴油直接进行冷机启动的效果差， 又由于乳化柴油的高黏度性质，如果长时间停止不用就容易出现部分 分离，这种情况下启动发动机，不仅会使部分柴油得不到充分的燃烧， 效率下降， 影响使用效果， 而且还容易产生有害气体，造成一定程度 的环境污染。此外， 由于乳化柴油是一种燃料， 它的最佳使用温度为
70-79 °C , 温度过高或过低都会影响其使用效果， 也会造成燃油的利 用不够充分。对目前已大量使用的直喷式柴油机， 因其直接将与环境 温度相同的低温燃油喷入气缸，严重影响了乳化燃油的使用效果。本 人申请的 200710134031. 6号名称为乳化柴油的高效助燃供油装置的 中国专利，公开了利用发动机冷凝水的热量为乳化柴油进行预热，可 使油温上升到 50°C左右， 再用电热管进行恒温辅助加热到 70- 79°C， 是一种节能型加热方案， 但由于刚幵机时， 发动机冷凝水的温度低， 不能起到加热作用， 电热管加热也需要滞后一段时间， 升温速度慢， 对于间隙性工作的柴油机或大型柴油发电机组等则不太适用。 发明内容
本发明的目的是为了克服上述助燃供油装置的不足之处，设计一 种升温速度快， 油温稳定的乳化柴油微波加热装置。

为了便于用微波对管内乳化柴油加热，所述螺旋管选用 PPR管或 聚丙烯、聚丙烯树脂、复合聚丙烯、聚酰亚胺制成的耐温塑料管， 螺 旋管的长度与微波加热器的数量相对应，螺旋管的内径与供油量相对 应。
为了使乳化柴油顺利通过螺旋管，可增设有增压泵，所述增压泵 串接在螺旋管输入端与乳化柴油管之间，即螺旋管输入端与增压泵输 出端连接， 增压泵输入端与乳化柴油管连接。
本发明的乳化柴油微波加热装置，由于微波能对螺旋管内的乳化 柴油直接加热， 具有升温速度快， 油温稳定等优点， 该装置既可单独 使用，也可与其它如冷凝水等预热装置配合使用。适合安装在各种使 用乳化柴油为燃料的柴油发动机的供油未端使用。可将供给柴油发动 机的乳化柴油保持在 70-79 °C的最佳使用温度之间， 有利于乳化柴油 充分燃烧，提高柴油发动机的工作效率和减少有害气体排放而有利于 环境保护。 是一种适合乳化柴油发动机使用的配套产品。
