强制循环结晶器

强制循环蒸发结晶器
一、概 述：
强制循环蒸发结晶器又称FC( Forced Circulation ）型结晶器，是一种可以连续生产的通用型结晶设备，广泛应用于化工、轻工、医药等行业的生产以及环保行业废水蒸发结晶处理。根据料液性质的不同，FC型结晶器分为加热蒸发型、间壁冷却型或真空冷却型等以满足各种结晶工艺的需要。
强制循环蒸发结晶器是由加热器对待处理的料液进行加热进入结晶分离室蒸发分离，溶液达到过饱和状态便产生结晶现象，由强制循环泵经多次循环加热后结晶室内过饱和溶液沉浸在悬浮晶粒表面上，使晶体逐渐长大，当晶体数量达到一定浓度时即可将晶浆排出另作处理。强制循环蒸发结晶器具有生产能力大，产品的粒度分布较宽，约在0.8~4mm 的范围，适应各种物料的结晶等特点。
二、结构组成：
强制循环蒸发结晶器主要由换热器、结晶分离室、冷凝器、循环管、循环泵、晶浆泵、真空泵、控制系统等组成；按物料浓度高低与生产能力的大小不同，可分为一效、二效、三效、四效强制循环蒸发器。

Forced Type Circulation Evaporation Crystallizer
I. Introduction
Forced Circulation Evaporation Crystallizer is a kind of continuous crystallizer with crystal slurry circulation. On production, raw solution feed from bottom of circulation pipeline,and then mixed with crystal slurry which left from bottom of crystallizer, the mixed fluid will be pumped into the heat exchanger,it will increase temperature in the heater (normal increase 2-6℃),but it will not evaporation. Once hot crystal slurry flow into crystallization chamber,after boiling, it will reached super saturation,so parts of solute sedimentate on the surface of suspended crystal, and then grow bigger,finally discharge out from the top of circulation tubes. FC Crystallizer have large production capacity, but product size dimension arranged widely.
II. Structure Component
Forced Circulation Crystallizer consist of Crystallization Chamber, circulation tubes, circulation pump and heat exchanger etc.
Crystallization Chamber designed with cone type bottom,crystal slurry discharge out from the cone bottom,pumped into the heat exchanger by Axial Flow pump through circulation tubes,after heating or cooling,re-back into the crystallization chamber,it will continue having such circulation running.that’s the reason it called crysta-slurry circulation type.crystal slurry discharge let is near the bottom of crystallization chamber,and feed let is lower then discharge level.
III. Usage 
Forced Circulation Evaporation Crystallizer widely used in the industry of chemical, light industry,pharmacy etc, for product manufacturing and waste water treatment. FC type Crystallizer could work for evaporation crystallization, batch cooling crystallization or vacuum cooling crystallization. Product size dimension during the range of 0.8-4mm.
