Abstract: Изобретение может быть использовано при получении чистого кислорода. Способ получения кислорода из воздуха характеризуется использованием генератора кислорода, который состоит из первого и второго адсорберов, каждый из которых содержит входные и выходные патрубки. Входные патрубки через входные клапаны подключены к линии подачи сжатого воздуха и через клапаны сброса к атмосфере. Выходные патрубки соединены между собой через перепускной клапан и ограничительную дюзу и через обратные клапаны с кислородным ресивером. Воздух из линии поступает через открытый входной клапан в первый адсорбер, который задерживает азот и пропускает кислород через обратный клапан в кислородный ресивер и через ограничительную дюзу во второй адсорбер. При этом происходит сброс азота в атмосферу через клапан сброса. После насыщения первого адсорбера азотом происходит выравнивание давления в адсорберах через перепускной клапан. Воздух из линии поступает во второй адсорбер, и цикл повторяется. В момент выравнивания давления в адсорберах оба входных клапана открыты, подача воздуха из линии осуществляется в оба адсорбера. Изобретение позволяет исключить воздушный ресивер на входе в генератор кислорода и снизить энергопотребление компрессора. 1 з.п. ф-лы, 1 ил.
