The utility model discloses a solution regeneration device based on flash evaporation. The solution regeneration device comprises a solution loop, a water vapor condensing loop and a low-pressure retaining loop. According to the solution regeneration device, throttling flash evaporation of a solution under low pressure is fully used, and water vapor is produced, so that the concentration of the residual solution is increased, and the solution is regenerated; furthermore, the solution regeneration rate and the solution regeneration concentration can be flexibly adjusted; meanwhile, the water vapor produced by flash evaporation is compressed so as to perform condensation to release heat, so that the low-concentration solution is heated, and effective use of water vapor condensation heat is realized; therefore, the whole device does not need a solution regeneration heat source any more, and self balance of solution regeneration energy is realized; the device is compact in structure, is flexibly and conveniently
