By rotating the X-axis of the measurement coordinates, the straightness data of each generatrix are transformed into a unified 3D coordinate system whose Z-axis superposes the least square mean axis calculated with the data of the multiple generatrices. The computer simulations and experiments prove that the construction by rotating the abscissas can effectively eliminate the distortion of the constructed profile.

The result showed that the conventional and optimum design model of complex multi-evaporation had good universality. The new algorithm could be used to solve model more stably and more effectivly. The energy-saving effect was notable when all kinds of energy-saving measure were adopted and T0, Tk, tpj,Δti were optimized. In these conditions, the annual cost of optimum design decreased by 36.44% and 40.76% respectively than conventional design for the complex cross-feed and parallel-feed quadruple-effect evaporation system with solid separation. An optimum design software for multi-evaporation was developed, which had strong function, amity interface and easy maneuverability. This software may be applied to conventional and optimum design of multi-evaporation system under different conditions.
