Product Description: SJN-1000~40000 Multi-effect fall-film vacuum evaporator


Multi-effect fall-film vacuum evaporator


Multi-effect Fall-film Vacuum Evaporator adopts falling film evaporating principal to heat the dilute solution to boiling, vaporized some water to get the concentrating solution. This set of device is a new production by our companys research and developed, and each technical index up to international advanced standards. Compared to traditional evaporator, our product enjoys widely used to in such fields as food processing, juice concentration, drinking production, dairy production, chemical industry, pharmaceutical industry, waste water treatment and environmental project etc, and having advantages of low cost, easy operation and stable performance.



 Main characteristics as follows:

1. Fast Heat Transmission and Energy Saving. As high efficient energy-saving concentrating equipment, the evaporator can be assembled into two-effect, three-effect, four-effect and five-effect evaporation system, fully utilizing heat energy and low steam consumption. One kilogram steam can evaporate four kilogram water. One effect evaporator goes through the jet heat pump, the pressure (pressure energy) convert to the speed (kinetic energy), so the evaporator shell works under vacuum state. The tail steam of one-effect enters into pre-heater with some secondary steam of the preheated liquid pumped into one-effect again by jet heat pump, making fully use of heat.



2. High Concentration Ratio (1/51/10), wide viscosity area (<400cp) Due to the falling film evaporation, the liquid film flows from top to bottom along the pipe wall. What's more, owing to the gravity, the high viscosity solution flows and evaporates easily without coking.



3. The equipment can adopt downstream continuous feeding, also can adopt up-stream or mixed-flow feeding. When adopting down-stream feeding, the flow direction of solution is the same as the flow direction of heating steam, and the material enters into the one-effect. However, when adopting up-stream feeding, inlet the material heated to boiling by pre-heater enter into the first effect. When adopting Up-steam feeding, the material enter from the last effect while outlet from the first effect.



4. The equipment can be controlled manually, as well as semi automatically or automatically. When controlled automatically, the technological parameters such as steam pressure, the temperature of each control point, liquid level, vacuum degree and feed liquid proportion etc, feedback their technical parameter to computer control system through the sensor, so the operator can control these parameter by computer in the control room.



5. The equipment can be made of different kinds of material according to different materials and technological demand, such as TA2 Titanium,1Cr18Ni9Ti stainless steel, ordinary carbon steel (surface contacting with material is bedaubed with special antiseptic and antirust paint). Under the condition of waste water treatment, bedaub the surface of ordinary carbon steel with special antiseptic and antirust paint can save a large sum of device investment, which have been tested by our factory repeatedly. So the equipment is really a preferred product for the wastewater treatment station.
