Standard Shell And Evaporator

Evaporation system belongs to the natural circulation evaporator, which is composed of heating chamber and evaporation chamberheating tube isΦ25-Φ75 wide and 0.6-2 meters long, There is a comparatively large downcomer in between of tube bundle, the cross section area is 40-100% in heating tube.

Due to difference temperature of downcomer and material liquid in heating tube, The heat transfer effect of evaporation is improved by continuous circulation between the heating tube and the drop tube.A total heat transfer coefficient of 580-3000 W/(㎡*K).This equipment is suitable for Solutions with low scale, small amount of crystallization precipitation and low corrosive. Equipment heat transfer surface up to hundreds of square meters

External heating evaporator belongs to New circulation external heating evaporator of heating tube type external boiling. Its structure is characterized by the addition of 2.7-5m high support section and steady flow section at the upper part of heating chamber, so solution in heating chamber will bear large liquid column static pressure, without boiling. Only in the steady flow section with low static pressure will it begin boiling and vaporization.

Natural external heating evaporator is an efficient, energy-saving, environmentally friendly, easy to operate, and widely applicable evaporation system, with broad application prospects.
