High Heat Transfer Coefficient TVR Evaporator In Pharmaceutical

Industrial High heat transfer coefficient Thermal Vapor Recompression TVR Evaporator in pharmaceutical production

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.

WORKING PRINCIPLE

The Evaporator Falling Film TVR is fed from the wet process area. From the balance tank product is heated to at least boiling temperature of the first calandria, depending on the final product demands. This can be done by plate heat exchangers, tubular heat exchanger and/or direct heaters by use of condensate, excess vapours, steam and/or hot water. After the heating process the product is fed to the first calandria where the product starts to evaporate. The evaporator works according the falling film principle, which means that product and vapour are flowing downwards through the tubes. At the bottom, concentrate falls down and vapour is sucked into the separator, whereby the smaller concentrate droplets are separated from the vapour. Concentrated product is pumped to the next pass, whereby the product is further concetrated. After the final calandria pass product is pumped, depending on the product and required concetrate properties, to a next calandria, concentrate tanks of the dryer or via a flash cooler to crystallisation tanks. As the amount of water evaporation is limited and the required temperature difference is relatively high, steam is used as driving force. This is referred to as thermal vapour recompression (TVR). Depending on capacity and specific product needs the number of stages and thermo-compressors are defined. A density controller in the concentrate flow is used to set the steam flow to the thermo-compressor.

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.
