Descriptions

In the forced circulation evaporation system, the material flows in the heat exchange tube at a speed of 1-3m/s through acirculating pump, and the temperature rises by 1-5 C .The state of crystal slurry and scaling-prone materials in evaporatorneat exchange tubes is equivalent to their movement state in the same size pipes and at the same flow rate, and theinfluence of a small amount of temperature change is not obvious, That is to say, under the same conditions, if the materiacan pass through a pipe, it can pass through the heat exchange tube of the evaporator. The specification of circulatincpump in forced circulation system is much higher than that in falling film system. For crystalizer, the head of circulatingpump is very low. The anti-scaling ablity of forced circulation evaporation system is stronger than that of faling filmsystem, and it is suitable for concentration or continuous crystalization of materials easy to scaleAccordina to the characteristics of evaporated materials, faling film and forced circulaion can be combined in the designt0 treat materlals with scalnd oroblems and contnuous crvstalizalon svstem, Pre-concentration ot materials is completerin falling film unit, and then enters forced circulation unit to complete final concentration or continuous crvstallizationsaving equipment investment and operation cost.

Features

It has the characteristics of wide range of concentrated materials, arge concentration ratio, high discharge concentration, full anti-fouling and anti-blocking.
