A two-effect falling-film evaporator with thermocompressor requires about 0.32 kg of steam to evaporate 1 kg of water, and a five-effect evaporator requires 0.09 kg of steam. Without the thermocompressor, the specific steam consumption would be approx. 0.55 and 0.2 kg per kg of water evaporation respectively.

Forced Circulating Evaporator

Forced Circulating Evaporator

After forced circulating, the evaporator is heated ev-enly in the pipe with high heat transfer coefficient, in order to prevent the occurrence of dry walls. 6. The materials and liquids are separated after coming into the separator. The effect of separating is greatly improved, and it is flexible to operate. 7.

Aug 29, 2019 Natural/forced circulation evaporator. ... The amount of evaporation that takes place depends on the temperature difference between the steam and the solution. Problems can arise if the tubes are not well-immersed in the solution. If this occurs, the system will be dried out and circulation compromised. ... Falling film evaporator.

Falling Film Tubular Evaporator - Thermal Kinetics

Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a combination of the two. The major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unit. Liquid entering the top of the unit passes either through a spray ...

May 01, 2021 In falling film devices, this process happens at the liquid-vapor interface. It means that the device can use a lower temperature, meaning less energy use and some other benefits. For example, as there is no nucleate boiling on the tube walls, the solution in the evaporator will not crystalize. These long-tube devices are very energy efficient ...

May 03, 2022 1) Multiple Effect Evaporator (MEE) In a multi effect evaporator, the secondary steam produced by the first effect does not enter the condenser, but will be reused as heating medium for second effect.The new steam consumption can be effectively reduced by about 50%. The new steam consumption can be further reduced by using this principle repeatedly.

Evaporator Systems- Manufacturing Principal Types

The compact evaporator operates by the simple falling film principle, in which fluid is pumped into the top of each heater through a liquid distributor and flows down the inside of each tube as a thin liquid film. Hot vapors condense on the outside tube walls, releasing heat that is transferred to the fluid. Vigorous boiling takes place as the ...

Forced circulation evaporation

Forced circulation evaporation

The forced circulation evaporator comprises a heat exchanger, a separator and a circulation pump. The product is sent to the exchanger where it is heated and then sent to the separator. After evaporation, the liquid portion is pumped again to be resent to the exchanger. The forced circulation evaporator is great for the following applications:
