Abstract

Изобретение относится к способу получения гранулированного перкарбоната натрия путем грануляции в псевдоразряженном слое, содержащем частицы перкарбоната натрия, в который через, по меньшей мере, одну многокомпонентную форсунку с внешним смешиванием распыляют водный раствор пероксида водорода и водный раствор карбоната натрия при одновременном испарении воды; причем раствор карбоната натрия дополнительно включает карбонат натрия и/или перкарбонат натрия в суспендированном виде, а перед подачей в многокомпонентную форсунку его пропускают через диспергатор для диспергирования твердых веществ.
