Abstract
<PICT:0817520/III/1> A process for concentrating and drying solutions or removing water of constitution comprises atomizing the solution or material by means of a nozzle into a flame zone located above a fall zone, said flame zone being in the form of an inverted cone, and spraying uniformly from above into the interior of the flame cone. In a preferred apparatus for carrying out the process, a material 9 to be treated is sprayed through nozzle 8 into a flame zone 7 produced by ring burner 6 and then passes into the atomization tower 2. Hot waste gases together with the resulting final product pass off through line 10 to a cyclone separator in which the product is removed, the gases are conducted through the heat exchanger 4 in countercurrent to fresh air which enters by supply line 12 and is then fed to the top of the atomization tower. The nozzle is preferably arranged above the ring burner at a distance equal to up to half the diameter of the ring burners. In examples: (1) and (2) sodium phosphate is produced by spraying a mixture of phosphoric acid and sodium carbonate; in (3) CaCl2 is dehydrated; and in (4) sodium sulphate is produced in anhydrous form.
