摘要： The disclosure relates to a process for making alkali metal phosphates, especially alkali metal polyphosphates, from alkali metal phosphate solutions or suspensions. To this end the solutions or suspensions are forced to flow through a plurality of single opening nozzle structures under a pressure of 6 to 66 bars and sprayed inside a tower through a flame zone produced by a plurality of burners arranged in annular fashion. The disclosure also relates to a device for carrying out the process, wherein a cylindrical spray tower (1) having a tapered lower end and being closed by means of a cover (2) has a solvent feed pipe (5) terminating in a spray means (6) centrally passed through the cover, and wherein a plurality of burners is passed through the cover (2), concentrically around the solvent feed pipe (5). The spray means (6) is comprised of a feed pipe (15) and at least one spray head (12), which has a plurality of single opening nozzle structures (17) disposed in its terminal surface area (13). At least one pressure-increasing pump ( 7) is disposed in the solvent feed pipe (5).
摘要翻译：本公开涉及由碱金属磷酸盐溶液或悬浮液制备碱金属磷酸盐，特别是碱金属多磷酸盐的方法。为此，溶液或悬浮液被迫在6至66巴的压力下流过多个单个开口喷嘴结构，并通过由以环形方式布置的多个燃烧器产生的火焰区域在塔内喷射。本公开还涉及一种用于执行该方法的装置，其中具有锥形下端并通过盖（2）封闭的圆柱形喷射塔（1）具有以喷射装置终止的溶剂供给管（5）（6）集中地通过所述盖，并且其中多个燃烧器同心地围绕所述溶剂供给管（5）通过所述盖（2）。喷雾装置（6）由进料管（15）和至少一个喷头（12）组成，喷头具有设置在其端表面区域（13）中的多个单开口喷嘴结构（17）。至少一个增压泵（7）设置在溶剂进料管（5）中。
