20 Jul 1983TL;DR: In this paper, a liquid diverting system is used for alternating the flow of water between the rotating spray arm and the extendable top spray tower to reduce the overall flow rate and the total water consumption.
Abstract: A dishwashing machine including upper and lower dish supporting racks and a liquid wash spray assembly having a rotating arm for spraying water upwardly on the lower dish load and an extendable top wash tube which sprays liquid at an intermediate level between the upper and lower dish supporting racks in the machine. A liquid diverting system provides means for automatically alternating the flow of water between the rotating spray arm and the extendable top spray tower. Water is directed continuously to a jet port on the spray arm which insures that the arm will continue to rotate independent of the liquid diverting system when the water is diverted to the top spray tower. The spray arm and tower each deliver effective water flow on an alternating basis while the overall flow rate and the total water consumption is reduced.

TL;DR: In this paper, a theoretical analysis of direct contact latent heat transfer between two immiscible liquids in a counterflow spray column is presented, where the non-dimensional parameters governing the evaporation process are identified and a study of the effects of the variation of these parameters is made.

TL;DR: In this paper, a process for making alkali metal polyphosphates was described, where a fine particulate solution or suspension was forced through at least one nozzle and then sprayed inside a spray tower through a flame zone produced by one or more burners arranged in annular fashion.
Abstract: The disclosure relates to a process for making alkali metal polyphosphates, especially alkali metal triphosphates. To this end, the disclosure provides for an alkali metal phosphate solution or suspension to be forced through at least one nozzle and for them to be sprayed inside a spray tower through a flame zone produced by a one or more burners arranged in annular fashion. More particularly, the disclosure provides for fine particulate alkali metal polyphosphates, especially alkali metal triphosphates, to be additionally introduced into the spray tower from above and for them to be regularly distributed across the spray region(s) of the nozzle(s) with formation of agglomerated products. The disclosure also relates to an apparatus for carrying out the process. The apparatus is comprised of a cylindrical spray tower (1) having a tapered lower end (3) and being closed by means of a cover (2); a spray means (6) being passed centrally through the cover (2); a plurality of burners (11) and a solid matter feed means being passed through the cover concentrically with respect to the spray means (6) and so as to be spaced therefrom; and a bevelled issuing gas outlet (4) opening upwardly from the tapered end of the spray tower (1).
