Regeneration Performance of High Concentration Solution by Mechanical Vapor Recompression System

Blog Article

A mechanical vapor recompression (MVR) system is an efficient evaporation system.In this study, the performance of an MVR system in generating high concentration CaCl2 solutions was studied through simulation analysis and experiments.The influence of input parameters, including evaporation pressure and inlet dilute solution concentration, on the regeneration performance of the MVR system was studied.The regeneration rate is affected by evaporation pressure on which the suction density is depended.The higher the evaporation pressure, the higher the regeneration rate and energy consumption of the system.

Under the condition that the concentration of the CaCl2 solution at the inlet was 0.3, the SEC value of MVR regeneration system increased from 46.67 to 79.51 kWh/m3, and the COP of the system decreased redken shades eq 07m driftwood from 14.4 to 8.

2 when the evaporation pressure increased from 20 to 80 kPa.The concentration of the inlet solution affects the regeneration performance of the stickers logos dallas cowboys MVR system by increasing the boiling point of the solution.The higher the concentration of the solution, the higher the boiling point, and the higher the power consumption of the compressor.Under the condition that the evaporation pressure was 20 kPa, the SEC value of the system increased from 36.68 to 75.

76 kWh/m3, and the COP of the system decreased from 18.1 to 9.1 when the concentration of inlet CaCl2 solution increased from 0.25 to 0.39.

In terms of solution concentration, equivalent moisture content, and evaporation pressure, the CaCl2 solution had the best regeneration performance in the MVR system compared with the LiCl and LiBr solutions.
