Abstract

15,990. Dunn, J. E. July 18, 1910, [Convention date]. Concentric straighttube apparatus. - Relates to an evaporator comprising concentric tubes 7, 15, between which the liquid passes and which are heated on the side remote from the liquid. The evaporator is either of the construction shown in which the liquid after passing once through the apparatus is discharged therefrom by a pipe 29, or is arranged as a bulk evaporator of the calandria type with an internal or external circulation of t h e liquid. The heating- medium enters the chamber 10 surrounding the tube 7 and passes thence by a pipe 12 to a chamber 13 supplying the inner tubes 15. The inner tubes are closed at their upper ends except for a small aperture through which uncondensed vapours escape. The outer tubes extend beyond the tube-plates 8, 9 and may be bevelled at their lower ends. A distributing-baffle 18 is fitted in the supply chamber 4. When arranged for multiple effect, the successive evaporators are provided with heating-elements having a decrcasing number of tubes, each of increasing evaporating surface; particulars of the dimensions adopted are given in the Specification.
