Product Description

It is suitable for single effect, multiple effect, and secondary steam compression (MVR) design, which has features of high heat exchange efficiency, low energy consumption and anti-scaling. It is widely applicable to the industries such as pulp and paper, grains, chemical, sugar, etc.


Working Principle:

1.The liquid to be evaporated is pumped into the distributor at the upper part of cylinder by the recirculation pump, and the liquid falls freely from the distributor and uniformly spreads on the surface of the heat transferring plate, then film is formed and liquid film flows into the liquid chamber at the bottom of the cylinder in the form of turbulence, and the liquid flowing downward is continuously heated and evaporated.

2. While the liquid is heated, generated vapor continuously rises up and flows through cylinder upper area into grated defoamer at the top of the cylinder, released by vapor pipe at the top, and functions as heat source for next evaporation effect. 


3. After heat-exchange, saturated steam in plate interior is cooled into condensate, flowing into the collector, and be discharged from the bottom of plates.

4. Heavily contaminated and lightly contaminated condensate are separated by plates depending on the amount of sulfide and the methanol substitute materials in the secondary vapor. 


Features:


High heat transfer coefficient.
Especially suitable for materials with heat-sensitivity and with viscosity less than 500CP.
Can evaporate solutions with low solids content.
Design with relatively small temperature difference, so with little heat loss.
Lower second vapor velocity, with less foam entrainment;
Optimum streamline heat transfer surface, with capability of redistribution;
Flat plane heat transfer structure, with scaling easy to be shed.
