Did you know?
Due to the intimate contact of the liquid with the heating surface, these evaporators are sensitive to fouling from precipitating solids. Low liquid velocity at the inlet is usually not sufficient to perform an effective self-cleaning of the tubes. Falling film evaporators are therefore used in clean, non-precipitating liquids. … See more A falling film evaporator is an industrial device to concentrate solutions, especially with heat sensitive components. The evaporator is a special type of heat exchanger. See more In general evaporation takes place inside vertical tubes, but there are also applications where the process fluid evaporates on the … See more Horizontal falling film evaporators have a number of potential advantages over their vertical counterparts in the petrochemical industry, … See more • Falling Film Evaporators • Wolverine Tube Heat Transfer Databooks See more Falling film evaporators have a number of advantages over their flooded evaporator counterparts. They require a lower charge, as the entire shell (in the case of horizontal evaporators) or all the tubes (in the case of a vertical … See more • Climbing and falling film plate evaporator See more WebFalling-film evaporators are constructed around a vertical bundle of large-diameter long tubes, with a liquid distributor on top and a vapor/liquid separator section below.

WebHow does an evaporator work? At first, the chemical compound is fed to the evaporator. It then passes across a heat source that the compound into a gaseous form (vapor). ... Falling film evaporator; Rising film (Long Tube Vertical) evaporator; Short Tube evaporator; Climbing and falling-film plate evaporator; Multiple- effect evaporator ... WebIn the operation of a falling film evaporator, fluid is pumped to the top of the heat exchanger and is evenly distributed across the tubesheet and into the heat transfer area. Proper wetting of the heat transfer area is required to maintain the dynamics of the evaporation process.
WebJan 27, 2024 · Falling film evaporators have tubes sprayed with refrigerant, which falls in cascade, covering them with a refrigerant film: hence the term falling film, recently introduced by Unilab in its SHELL software for Shell & Tube heat exchangers. WebA multiple-effect evaporator, as defined in chemical engineering, is an apparatus for efficiently using the heat from steam to evaporate water. [1] Water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapor boiled off in one vessel ...
