Description

Известны воздухоразделительные установки с выдачей газообразного кислорода под избыточным давлением, содержащие ректификационную колонну с конденсатором-испарителем, теплообменник-газификатор и насос, установленный между колонной и теплообменником. В этих установках газообразный кислород выдаетс  под избыточным давлением равномер но , независимо от режима потреблени , а регулирование расхода осуществл етс  созданием запаса газообразного кислорода под давлением в буферных емкост х.Known air separation plant with the issuance of gaseous oxygen under pressure, containing a distillation column with a condenser-evaporator, a heat exchanger-gasifier and a pump installed between the column and the heat exchanger. In these plants, gaseous oxygen is released under excess pressure evenly, regardless of the consumption mode, and flow control is carried out by creating a supply of gaseous oxygen under pressure in buffer tanks.

Предлагаема  установка отличаетс  от известной тем, что к конденсатору-испарителю подключены сосуд Жидкого кислорода, св занный через регулирующий орган с насосом, и сосуд жидкого азота, св занный через регулирующий орган с теплообмепником-газ:Ификатором . Это обеспечивает возможность, неравномерной выдачи газообразного кислорода в зависимости от нужд потребител  непосредственно с усталовки без устройства буферных емкостей и без изменени  тепловых нагрузок основных аппаратов.The proposed installation differs from that known in that a liquid oxygen vessel connected through a regulator to a pump and a liquid nitrogen vessel connected through a regulator to a heat exchanger-gas: Ifikator are connected to the condenser-evaporator. This provides the possibility of uneven delivery of gaseous oxygen, depending on the needs of the consumer, directly from the installation without installing buffer tanks and without changing the thermal loads of the main apparatus.

На чертеже изображена предлагаема  установка .The drawing shows the proposed installation.

Установка работает следующим образом.The installation works as follows.

Жидкий кислород отбирают из конденсатора-испарител  2 насосом 4 и под давлением направл ют в теплообменник-газификатор 3 и частично в сосуд 5 жидкого кислорода через регулирующий орган 7. В теплообменнике-газификаторе жидкий кислород газифицируют под необходимым давлением за счет тепла встречного теплого потока, вводимого в установку , и направл ют потребителю. Расход кислорода в зависимости от нужд потребител  регулируют измепением количества жидкого кислорода , отводимого после насоса в сосуд жидкого кислорода. Нормальный температурный режим теплообменника 3 при снижении потреблени  кислорода поддерживают подачей в теплообменник-газификатор необходимого количества жидкого азота из сосуда 6. В последнем жидкий азот накапливают путем посто нного отбора из линии подачи жидкого азота из конденсатора-испарител  2 на верх ректификациониой колонны /. Количество отбираемого жидкого азота регулируют пр.и помощи вептил  8. При подаче жидкого азота через теплообменник-газификатор автоматически поддерживают посто нной температуру встречного потока (Г const) при помощи регулирующего органа 9.Liquid oxygen is taken out of the condenser-evaporator 2 by pump 4 and sent under pressure into the heat exchanger-gasifier 3 and partially into the liquid oxygen vessel 5 through the regulator 7. In the heat exchanger-gasifier, liquid oxygen is gasified under the required pressure due to the heat of the counter-warm flow introduced to the installation and sent to the consumer. The consumption of oxygen, depending on the needs of the consumer, is regulated by measuring the amount of liquid oxygen discharged after the pump into a vessel of liquid oxygen. The normal temperature of the heat exchanger 3 while reducing oxygen consumption is maintained by supplying the required amount of liquid nitrogen from vessel 6 to the heat exchanger-gasifier. In the latter, liquid nitrogen is accumulated by continuously withdrawing from the supply line of liquid nitrogen from the evaporator 2 to the top of the distillation column. The amount of liquid nitrogen to be taken out is controlled by the help of the aid of the Veptils 8. When supplying liquid nitrogen through the heat exchanger-gasifier, the temperature of the counter flow (G const) is automatically maintained by the regulator 9.

держ,ивают автоматически изменением количества жидкого кислорода, подводимого к конденсатору из сосуда жидкого кислорода через регулирующий оргаи 10. Дл  создани  необходимого напора жидкого кислорода сосуд жидкого кислорода располагают выше конденсатора-испарител  и газовые полости этих двух аппаратов сообщают между собой.holding, automatically, by changing the amount of liquid oxygen supplied to the condenser from the liquid oxygen vessel through the regulator. 10. To create the necessary pressure of liquid oxygen, the liquid oxygen vessel is located above the condenser-evaporator and the gas cavities of these two devices communicate with each other.
