Structure and performance

Single-effect evaporator is composed by one heating room and one vapor-liquid separating room. This evaporator unit is composed by two or more evaporators, heat pump, various feeding and discharging pumps, vacuum device, test instrument, pipeline and valve. The heating room is mostly composed by crust, pipe bundling device and connection pipe. And vapor-liquid separating room is composed by crust and foam eliminator.

a.This machine unit feeds material continuously in downstream or in upstream or in mixed flow. If feeding in downstream, the flow direction of solution is the same as that of steam during heating. Raw material is preheated to boiling point by pre-heater and then reaches to the first effect. As the boiling point of solution in former effect is higher than that in latter effect, material will be overheating and evaporate by itself once entering to the latter effect, meanwhile, as the condensed water in former effect can also evaporate after coming into the latter effect, secondary stream will be produced more. If feeding in upstream, raw material is fed in the third effect. The first-effect material is discharged through the second-effect one. When feeding mixed material, raw material is fed by the third-effect material and is discharged by the second-effect one through the first effect.
b.Relying on the effect of heat-insulation compression, steam eject heating pump makes some secondary steam in the first effect improve its saturation temperature and return to the first-effect heating room to act as heating steam, thus, economic degree for producing steam is improved. 
c.The static distribution panel makes material form film-like flow evenly and effectively after entering into feeding pipe from the top of heating room, so the coefficient of heat transfer is improved greatly; and temperature loss caused by static-pressure head may be omitted; therefore, the effect temperature difference is much large in the condition of the same falling film evaporator.
d.As solution stays for short time in evaporator, it is much suitable for evaporating heat-sensitive material.
