Thermal Vapor Recompression Evaporators

Factory price for Thermal Vapor recompression evaporation system according to customers' requirement


thermal vapor recompression (TVR) evaporators use a thermocompressor to reduce the steam required per pound of evaporation—ultimately reducing energy consumption and saving costs.


How Thermal Vapor Recompression Evaporators Work

To reduce energy consumption, water vapor from an evaporator is entrained and compressed with high pressure steam in a thermocompressor so it can be condensed in the evaporator heat exchanger. The resultant pressure is intermediate to that of the motive steam and the water vapor. A thermocompressor is similar to a steam-jet air ejector used to maintain vacuum in an evaporator.

Only a portion of the vapor from an evaporator can be compressed in a thermocompressor with the remainder condensed in the next-effect heat exchanger or a condenser. A thermocompressor is normally used on a single-effect evaporator or on the first effect of a double- or triple-effect evaporator to reduce energy consumption. Like mechanical recompression, thermal recompression is more applicable to low boiling-point rise liquids and low to moderate differential temperatures in the heat exchanger to minimize the compression ratio.

The double-effect evaporator with thermal recompression requires 33% less steam than the conventional double effect. In essence, the steam usage for the double effect with thermal recompression is comparable to that of a triple-effect evaporator.


Features of thermal vapor recompression evaporation crystallizer:

1. In the process of thermal vapor recompression, the steam in the boiling chamber is recompressed to a higher pressure in the heating chamber according to the heat pump principle.

2. The saturated steam temperature corresponding to this heating steam pressure is high


Thermal vapor recompression evaporation crystallizer parameters:

Evaporation(t/h) 0.5-4

Raw steam consumption(t/h) 0.2x evaporation/three-effect meter

Raw steam pressure(MPa) 0.2-0.4

Steam energy consumption ratio(t/t) 0.02

Electric power(Kw) (28-62)x evaporation

Compressor provides temperature range 10-40℃

Evaporation temperature range 40-80℃
