Factory price for Thermal Vapor recompression evaporation system in environmental waste water treatment
TVR evaporators use Thermal Vapour Recompression to recompress a portion of the vapour from the vapour separator and mix it with the steam to heat the first stage.
Process for TVR evaporator
Thermal Vapour Recompression (TVR) normally takes place across one or more stages by utilizing medium or high pressure steam in an ejector which recycle a portion of the vapour from the vapour separator and mixing it with the steam. This mixture is used for heating of the first evaporation stage.
The steam consumption for a TVR evaporator will vary between approx. 0.3 - 0.07 kg steam per kg water evaporation depending on the number of stages over which the recompression takes place.
This design provides for less costly machinery than straight steam heated designs but requires motive steam pressure.
Thermal Vapor Recompression Evaporators
thermal vapor recompression (TVR) evaporators use a thermocompressor to reduce the steam required per pound of evaporation—ultimately reducing energy consumption and saving costs.
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:
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℃
