Unikan - Model MVR -Horizontal Falling Film Evaporator
The MVR horizontal falling film evaporator is very suitable for industries of food&beverage,chemicals,pharmaceuticals,waste water treatment,etc... The material liquid is firstly pumped into the system and pre-heated by plate heat exchangers where the heat souce comes from condensate and concentrated liquid,in order to make full use of the heat source.Then it goes into the top of the horizontal evaporating chamber spraying out and flows down the pipelines on shell side.While the vapour goes through the horizontal pipeline and makes heat exchanging with material liquid.
During the liquid down flowing along with the pipeline as film,its temperature is rising and begins to evaporate.When the liquid is being concentrated,the vapour is generated and transfered into the compressor to raise its temperature and pressure.After compressed,the high-temperature and pressure vapour will be tranfered back into the horizontal pipelines as heating source.Thus,more and more vapour is compressed and recycled without using original steam source.
Horizontal falling film MVR system nowadays which is explored and designed by our company.Taking place of the high vertical evaporating chamber,it uses the horizontal evaporating chamber which will save much space occupation and easily for operation and maintenance.Because of its special horizontal falling film principle,it can even save more 10-15% electric consumption,compared with the MVR vertical falling film evaporation system.
The composition of MVR horizontal falling film evaporation system
