Multi Effect Sodium Chloride Industrial Salt Line Mvr Falling Film Vacuum Evaporator For Salt Making
Multiple Effect Evaporation
The multiple effect evaporation processes can optimise the energy efficiency of facilities through the recycling of vapour.
Functioning
During the first effect, the vapour provided generates vapour at a lower pressure. These vapours are then employed as a vapour heating steam in a second effect.
The number of effects might range from one to eight. The quantity of effects is determined by the investment and operating costs.
The vapours at the last effect's output should be condensed.
Example Parallel flow principle
The first stage's evaporator circuit is where the solution is introduced. Here, it combines with the circulating solution and receives steam heating in heater H. In the evaporator V1, the water-based solvent evaporates as the solution is cooled to boiling point. The second stage, which is run at a lower temperature and lower pressure, receives the solution after that. The solution is evaporated in the second stage using the vapour produced in the first stage as a heating medium. Depending on the elevation of the solution's boiling point and the frame circumstances at the time, this procedure may be repeated numerous times.The vapour of the last stage is condensed via cooling water. If salt shall be crystallized in the plant, further evaporation concentrates the solution to such an extent that crystals are formed. If desired, the crystals in the suspension can then be separated from the solution and dried.
Suitable for any type of evaporator
The multiple effect evaporator can be made up of falling film, forced or flash-cooling circulation evaporators.
Application
This technology is great when the cost of vapour is low.
Major Advantages of Multi-effect systems:
Ability to maximize usage of input energy (steam economy)
Reduced energy required to run full system
Reduced condensing load with additional effects (less cooling water needed)
Liquor flow control
Convenient foul condensate collection and processing
Ability to do online cleaning of individual effects
Maximum thermal efficiency with concurrent flow option
