Automatic Thermal Vapor Recompression TVR Evaporation System with local service
Thermal Vapor Recompression (TVR)
A method to reduce the energy consumption of a steam heated evaporator system.
Uses high pressure steam as the motive fluid to a steam ejector, to entrain recycled lower pressure steam and discharge the combined steam at a more useful intermediate pressure.
The vapor compression cycle relies on the condensation temperature of the lower pressure steam increasing with the increase in pressure.
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.
