強(qiáng)制循環(huán)蒸發(fā)結(jié)晶器

一、概 述：

強(qiáng)制循環(huán)蒸發(fā)結(jié)晶器又稱(chēng)FC( Forced Circulation ）型結(jié)晶器犀呼，是一種可以連續(xù)生產(chǎn)的通用型結(jié)晶設(shè)備幸撕，廣泛應(yīng)用于化工、輕工外臂、醫(yī)藥等行業(yè)的生產(chǎn)以及環(huán)保行業(yè)廢水蒸發(fā)結(jié)晶處理坐儿。根據(jù)料液性質(zhì)的不同，F(xiàn)C型結(jié)晶器分為加熱蒸發(fā)型宋光、間壁冷卻型或真空冷卻型等以滿(mǎn)足各種結(jié)晶工藝的需要貌矿。

強(qiáng)制循環(huán)蒸發(fā)結(jié)晶器是由加熱器對(duì)待處理的料液進(jìn)行加熱進(jìn)入結(jié)晶分離室蒸發(fā)分離，溶液達(dá)到過(guò)飽和狀態(tài)便產(chǎn)生結(jié)晶現(xiàn)象罪佳，由強(qiáng)制循環(huán)泵經(jīng)多次循環(huán)加熱后結(jié)晶室內(nèi)過(guò)飽和溶液沉浸在懸浮晶粒表面上逛漫，使晶體逐漸長(zhǎng)大，當(dāng)晶體數(shù)量達(dá)到一定濃度時(shí)即可將晶漿排出另作處理锉择。強(qiáng)制循環(huán)蒸發(fā)結(jié)晶器具有生產(chǎn)能力大土霞，產(chǎn)品的粒度分布較寬，約在0.8~4mm 的范圍沟脓，適應(yīng)各種物料的結(jié)晶等特點(diǎn)每访。

二、結(jié)構(gòu)組成：

強(qiáng)制循環(huán)蒸發(fā)結(jié)晶器主要由換熱器咨捕、結(jié)晶分離室闰收、冷凝器、循環(huán)管础川、循環(huán)泵淀税、晶漿泵、真空泵韵绿、控制系統(tǒng)等組成狂篇；按物料濃度高低與生產(chǎn)能力的大小不同，可分為一效赁栈、二效岗屏、三效、四效強(qiáng)制循環(huán)蒸發(fā)器漱办。

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.
