Detailed description

Multi effect counter current, counter current and falling film evaporator series equipment is used for the evaporation and concentration of corn pulp, fermented sugar juice industry, fruit juice, beverage industry, milk, liquor tank filtrate, pharmaceutical industry, fermentation liquid, high concentration organic or chemical wastewater. The utility model has the advantages of energy saving, short heating time, suitable for evaporation, concentration and large concentration ratio of materials with high viscosity, and can obtain deionized water with excellent quality to meet the needs of industrial boiler water. It can be combined into double effect, three effect, four effect and five effect evaporation systems. The waste steam from the top of tube bundle or disc dryer and other low calorific value heat sources (such as condensate steam) can also be used as the heat source of evaporator to become waste heat evaporator, which can greatly reduce the consumption of steam and achieve great energy saving effect. When there is sufficient supply of waste heat steam, no steam can be generated and remarkable economic benefits can be achieved.

working principle:

The material is evenly distributed to each evaporator pipe through the distributor. Under the action of gravity and secondary steam in the form of self evaporation, the material forms a spiral film flow from top to bottom. At the same time, the heat exchange between the material film and the steam on the outer wall of the tube makes the water in the material heated and evaporated. The stable temperature difference and heat transfer area form a stable amount of water evaporation, which is formed by the evaporated water The secondary steam has been used for many times to make great use of heat energy, reduce steam consumption and form the design principle of multiple evaporation.

Big performance features:

The distribution plate of the evaporator is spiral, the material distribution is particularly balanced, the liquid is absolutely falling along the inner wall of the tube, and it is suitable for sugar concentration

The top cover of evaporator is flat, which is convenient for cleaning and maintenance.

If the production capacity does not need large evaporation capacity. The heat exchange area can be changed.

Vacuum system can be selected by user, water ring vacuum pump or water jet pump.

Condensate can be recycled.

When the evaporation capacity is 3900kg / h, the steam consumption is 1300kg / h.

The heat dissipation is small, especially the secondary steam.

It is easy to operate and occupies a small area.
