Description
Известны способы регенерации силикагел в установках осушкн водорода при получении его электролизом водного раствора щелочей с помощью гор чих газов, например азота. Однако эти способы технологически сложны и св заны с затратами электроэнергии.There are known methods for the regeneration of silica gel in installations drying hydrogen when it is obtained by electrolysis of an aqueous solution of alkali using hot gases, for example nitrogen. However, these methods are technologically complex and are associated with energy costs.
По предлагаемому способу, с целью упрощени технологического процесса и снижени стоимости производства, регенерацию отработанного силикагел производ т влажным водородом, поступающим из прокалочных печей при температуре 200-250°.According to the proposed method, in order to simplify the technological process and reduce the cost of production, the regeneration of spent silica gel is carried out with wet hydrogen coming from calcining furnaces at a temperature of 200-250 °.
Установка дл осушки водорода в соответствии с предлагаемым способом содержит три заполненных силикагелем колонки, св занные между собой необходимыми коммуникаци ми с переключающей арматурой . Кажда из колонок работает поочередно в три цикла:The unit for hydrogen drying in accordance with the proposed method contains three columns filled with silica gel, which are interconnected by necessary communications with switching valves. Each column operates alternately in three cycles:
а)рабочий цикл, во врем которого силикагель осушает проход щий через него водород;a) a duty cycle during which the silica gel dries the hydrogen passing through it;
б)остывание, во врем которого силикагель охлаждаетс уже осушенным водородом;b) cooling, during which the silica gel is cooled with already dried hydrogen;
в)регенераци , при которой гор чий влажный водород из прокалочных печей проходит через отработанны силикагель и отбирает из него влагу.c) regeneration, in which hot, humid hydrogen from calcining furnaces passes through spent silica gel and takes moisture from it.
Водород, полученный электролизом водного раствора щелочей, очищаетс от кислорода в прокалочных печах при температуре 650-700, охлаждаетс в холодильнике до температуры 200-250° и поступает в колонку с силикагелем, работающую в цикле регенерации. Затем водород поступает в следующий холодильник, в котором отдел етс больша часть влаги, а из него в колонку дл топкой осушки. Холодный осушенный водород поступает в третью колонку с силикагелем дл охлаждени последнего и выводитс из установки.The hydrogen obtained by the electrolysis of an aqueous alkali solution is purified from oxygen in calcining furnaces at a temperature of 650-700, cooled in a refrigerator to a temperature of 200-250 ° and fed to a silica gel column operating in a regeneration cycle. The hydrogen then enters the next cooler, in which most of the moisture is separated, and from it into the column for drying furnace. The cold dried hydrogen enters the third silica gel column to cool the latter and is removed from the unit.
Предлагаемый способ позвол ет осушать водород до влажности 0,1-0,2 г/л13 без дополнительных потерь электроэнергии.The proposed method allows hydrogen to be dried to a moisture content of 0.1-0.2 g / L13 without additional energy losses.
