A compact and economical array of vertical tube evaporators is disclosed in a multi-effect process, for desalination of sea water, brackish water, and in general to any water with dissolved solids, in order to produce fresh water for oil offshore platforms, ships, and for some arid locations, using rejected waste heat of thermal machines. This invention is based on a concentric disposition of the evaporators or stages, having three different specially designed evaporators, which the first stage is a shell and tube evaporator built in a ring format, named Ring Shell And Tube Evaporator, including an internal shell, and having a vapour chamber above its upper tubesheet; the intermediate stage is a bundle of tubes in a ring format named Ring Bundle Evaporator, having a vapour chamber above its upper tubesheet; and the last stage that is a bundle of tubes in a circular arrangement named Cylindrical Bundle Evaporator.
“Desalinization Machine”, comprising of a series of vertical tube bundles, each bundle compounding an evaporator or stage, supported and sealed by an upper and a bottom tube sheet, in a multi effect process, characterised by having the assembling of the stages in a concentric disposition (FIGS. 1, 10 and 16), where the first stage is a shell and tube exchanger in a ring format, here named Ring Shell and Tube Evaporator (FIGS. 3 and 11) having a free space at the centre of the bundle, where is inserted the next stage or intermediate stage that is a bundle of tubes in a ring format, here named Ring Bundle Evaporator, having also a free space in the centre (FIG. 12), where is inserted the next stage that could be another intermediate stage or the last stage that is a bundle of vertical tubes here named Cylindrical Bundle Evaporator (FIG. 5).
