产品简介

详细介绍

概述：

多效蒸发器，由较原始的蒸发釜，发展成单效、双效、三效、四效或者更多效蒸发器，其目的都是为了逐渐减少能源消耗。多效蒸发器是由相互串联的多个蒸发器组成。是利用前一效蒸发产生的二次蒸汽为下一效提供热源，来达到节能的目的。多效可以回收部分的二次蒸汽，效数越多回收的二次蒸汽越多。这一点有别于MVR蒸发器能够回收全部的二次蒸汽。一般米说:三效蒸发每吨水消耗0.37~046吨蒸汽，四效蒸发每吨水消耗0.3~035吨蒸汽，五效蒸发每吨水消耗0.24-0.3吨蒸汽。我们公司的多效蒸发系统，往往考虑回收冷凝水或二次蒸汽的热量，来实现节能的目的。在废水处理中，还要考虑预热器结垢的自动在线清洗。多效蒸发器可以采用强制循环、自然循环、降膜、升膜、板式蒸发器等多种形式，也可以采用多种组合的方式，来较优化工艺。多效蒸发的流程:可以有顺流、逆流、平流、错流等。

Multi-effect evaporators have been developed from primitive evaporation kettles to single-effect,double-effect, triple-effect, four-effect or more effect evaporators,all of which are aimed at gradually reducing energy consumption. The multi-effect evaporator is composed of a plurality of evaporators connected in series. The secondary steam produced by evaporation in the previous effect is used to provide heat source for the next effect,so as to achieve the purpose of energy saving.Multi-effect can recover part of secondary steamａnd the more effectsthe more secondary steam will be recovered, This is different from the fact that MVR evaporator can recover al the secondary steam. Generally speaking,three-effect evaporation consumes 0.37~0.46 tons of steam per ton of water.four-effect evaporation consumes 0.3~0.35 tons of steam per ton of water,ａnd five-effect evaporation consumes 0.24~0.3 tons of steam per ton of water. The multi-effect evaporation system of our company often considers recovering the heat of condensed water or secondarv steam to achieve the purpose of energy savingIn wastewater treatment,automatic on-line cleaning of preheater fouling shouldalso be considered. Multi-effect evaporators can adopt forced circulation.naturalcirculation.fallina film. rising film.plate evaporator and other forms, and can also adopt various combinations to optimize the process.
