A structure for a multiple-effect still includes a horizontal shell (20) encompassing a plurality of effects (12) and a series of vertical compound baffles (214) fastened to the horizontal shell and dividing it into a series of pressure-tight chambers (10). Each chamber along with its associated apparatus constitutes an effect. Each compound baffle comprises a fixed baffle (252) and a removable baffle (254). A heat exchanger is fastened to the removable baffle and includes an evaporation surface, a condensation surface, and a pressure chamber isolated from the pressure-tight chamber in which it is located. A port in the compound baffle allows evaporate (66) to pass between the pressure chamber and the pressure-tight chamber of an adjacent effect. The shell is provided with a removable top plate (230) to provide access to the heat exchanger and allow removal of the heat exchanger and removable baffle. |
