The invention relates to a mechanical processing waste liquid evaporation device. The evaporator connects the waste liquid trough through a filter, uses a vacuum pump to wash the air in the evaporator to make the vacuum degree. The compressor pressurizes the refrigerant so as to release heat during the process of transforming it into a liquid. The heat is transferred to the waste liquid by the radiation coil in the evaporator, and the refrigerant evaporates. The coil of the evaporator is cooled to liquid and then vaporized in the coil of the condensing tank to cool down. The steam evaporated from the evaporator condenses into clear water in the condensing tank. With the evaporation of the waste liquid in the evaporator, the concentration of the waste liquid increases gradually, the evaporation temperature increases gradually until the end point of the evaporation, the system stops running, and the relief valve at the bottom of the evaporator is opened. The concentrate is packed in barrels. The invention applies the refrigerating machine technology with special mechanical structure to evaporate and treat the waste liquid of mechanical processing, and achieves good effects such as low energy consumption, high concentration ratio, non-blocking and NO-adding defoamer. The economic index is obviously superior to the imported and domestic products of the same kind, and the equipment occupies a small area and has low energy consumption.

一种机械加工废液蒸发装置
本专利技术涉及机械加工行业废液处理
,尤其涉及一种机械加工废液蒸发装置。
技术介绍
近年来,随着国家环保要求逐渐提高,对危险废弃物处置管理逐渐严格,部分企业从原先的灰色操作转为合法处置,导致近年来全国危废处置厂商的业务量显著上升,多地更是发生危废囤积数月甚至整年无法找到处置商外运的情况,企业无法在厂内存放大量危废,出厂堆放又会违法,导致企业生产受影响。在这种危废处置产能严重紧缺的情况下,危废的处置价格近年来逐年高涨。目前作为危险废弃物的机械加工废液,价格普遍已高于2500元/吨,部分焚烧类危废处置价格已高于1万/吨。为了避免危废无法外运而导致企业停产,也为了降低企业的运行成本,目前企业需要在自己厂区内实现危废的减量化,同时各地环保部门在改扩建或新建项目做环评时必须落实排污总量控制,因此各企业必须要实现危废的减量化。
