Product Features 产品优势 废水的组成比较复杂，没有一种固定的方式可以处理所有的废水。我们针对高危的委外废水进行分类，通过我们自身设备的多种组合，可以对大部分的切削废水、重金属废水、半导体加工废水、高COD废水进行浓缩处理，与EVCS系列蒸发结晶设备配合使用可达到零排放。 EVCO的模块系统设备可以为客户提供定制化的服务；设备结构紧凑，操作方便；强制循环防止管道结垢；蒸汽闭路循环降低能耗，至高可达95%的能源循环利用；设备采用PLC控制，智能化运行；自动化学清洗让运转更加流畅；可根据客户需求对馏分进行自动控制。
Principles and Features 工作原理及特性 物料原液从换热器加入，经过布液器把物料分配到每根换热管内，并且沿着换热管内壁形成均匀的液体膜，管内液体膜在向下流的过程中被壳程的加热蒸汽加热，边向下流动边沸腾并进行蒸发。到换热管底端物料变成浓缩液和二次蒸汽。浓缩液落入下蒸发室，二次蒸汽进入气液分离器。在气液分离器中二次蒸汽夹带的液体飞沫被去除，纯净的二次蒸汽从分离器中输送到蒸汽压缩机。蒸汽压缩机把二次蒸汽压缩后作为加热蒸汽输送到换热器壳程用于蒸发器热源。实现连续蒸发过程。
