Claims (1)
- В способе хлорщелочного электролиза, выполняемом в диафрагменном электролизере, содержащем пары чередующихся анодов B и катодов, катоды имеют отверстия и покрыты пористой диафрагмой, стойкой к коррозии, причем по крайней мере часть анодов B снабжена гидродинамическими средствами D для обеспечения циркуляции анодного рассола, причем электролизер имеет входы M для подачи свежего рассола и выходы для удаления получаемых хлора, водорода и каустика, при этом улучшение заключается в контроле кислородосодержания в хлоре и конструкции хлората в каустике, независимо от вводимого указанного свежего рассола и от концентрации указанного рассола, добавлением водного раствора хлористо-водородной кислоты к рассолу в анодном отсеке электролизера через распределитель, расположенный выше гидродинамических средств D.
