Automatic Thermal Vapor Recompression TVR Evaporator
TVR evaporation and concentration equipment
It is an evaporation concentration crystallization equipment which
uses TVR heat pump to recompress part of secondary steam as heat
source of heating chamber.
The supply conditions for stable supply of saturated steam above
0.7MPa are required.
The performance of TVR is directly related to the effect of steam
saving, so it is necessary to use products with guaranteed
operation performance.
If the quality and performance of TVR is poor, the steam saving
effect is not obvious, and it is easy to damage because of the
noise and vibration.
Process description
The solution is preheated with condensate and enters the
evaporation circuit. Here it mixes with the circulated solution and
is warmed up in heater H. In the evaporator V, solvent (water)
evaporates while cooling the solution to the boiling temperature.
The resulting vapour steam is compressed to a higher pressure and
temperature level by the steam jet pump with the help of steam, so
that it can be used as a heating medium for heating the circulated
solution. The excess vapour is condensed. If salt shall be
crystallized in the plant, further evaporation concentrates the
solution to such an extent that crystals are formed. If desired,
the crystals in the suspension can then be separated from the
solution and dried.
Characteristics
Only a fraction of the evaporation energy has to be used in the
form of live steam.
Low investment costs.
Retrofitting in existing plants is possible.
Suitable for various applications.

This equipment is a continuous concentration equipment, which is
composed of TVP steam heat pump, heating tube, evaporation chamber,
condenser, vacuum pump, circulating discharge pump and operation
platform. It is suitable for concentration in food, pharmaceutical,
chemical, bioengineering, environmental engineering, waste liquid
recovery and other industries. This equipment adopts TVR heat pump
technology, so as to save a lot of energy. Adding TVR heat pump can
save energy, at least equivalent to one more effect, that is, the
steam consumption of four effect + TVR is basically the same as
that of five effect.
