Abstract

В заявке описаны способ и устройство для очистки от твердых частиц полимера трубы, которая соединена с циркуляционным реактором. Устройство имеет датчик (441) давления в циркуляционном реакторе (1), установленный на идущем к нему трубопроводе, сообщаемый с ним первый клапан, второй клапан (418), расположенный между трубопроводом (416) и первым источником (412) инертного разбавителя и сообщаемый с трубопроводом (416) в точке, расположенной между циркуляционным реактором (1) и первым клапаном. По сигналу датчика (441) первый клапан закрывается, а второй открывается, обеспечивая поступление в трубу инертного разбавителя в необходимом для ее очистке от твердых частиц полимера количестве и достаточном давлении.Отчет о международном поиске был опубликован 2000.08.31.
