Изобретение относитс к хранению сж иженных газов в подземных низкотемпературных резервуарах без внутренней облицовки и может быть использовано на предпри ти х газовой , нефтехимической и химической промышленности при хранении сжиженного азота , метана, пропана, аммиака, этилена и др.The invention relates to the storage of compressed gases in underground low-temperature tanks without lining and can be used in the gas, petrochemical and chemical industries during storage of liquefied nitrogen, methane, propane, ammonia, ethylene, etc.
Известен способ защиты от разрушени стен льдогрунтового резервуара дл хранени сжиженного газа путем смачивани внутренней поверхности резервуара сжиженным газом .A known method of protection against the destruction of the walls of an ice-ground tank for storing liquefied gas by wetting the inner surface of the tank with liquefied gas.
Цель изобретени - защита стенок от сублимационного разрушени . Дл этого смачивание производ т хранимым сжиженным газом , который подают по периметру стен до получени сплошной пленки.The purpose of the invention is to protect the walls from sublimation destruction. For this, wetting is carried out with stored liquefied gas, which is fed around the perimeter of the walls until a continuous film is obtained.
Пример осуществлени способа показан на чертеже.An example of the method is shown in the drawing.
Резервуар 1, имеющий ледонородную оболочку 2, перекрытие 3, покрывают слоем льда 4 способом набрызгивани или заполнени водой с последующей откачкой. В результате достигаетс выравнивание, а значит более равномерное смачивание внутренней поверхности сжиженным газом и, кроме того, повышаетс The tank 1, having the glacial shell 2, the overlap 3, is covered with a layer of ice 4 by spraying or filling it with water, followed by pumping. As a result, alignment is achieved, which means that the inner surface is more uniformly wetted with liquefied gas and, in addition, increases
надежность защиты. Под перекрытием 3 ледопородную оболочку 2 делают с откосом 5 в сторону резервуара и также покрывают льдом, что обеспечит равномерное образование пленки сжиженного газа по внутренней поверхности стенок в парофазном пространстве, наход щимс над зеркалом продукта 6. Стены смачивают с помощью коллектора 7 с отверсти ми .reliability of protection. Under the overlap 3, the ice-breeding shell 2 is made with a slope 5 towards the tank and is also covered with ice, which will ensure the uniform formation of a film of liquefied gas on the inner surface of the walls in the vapor-phase space above the product 6 mirror. The walls are moistened with a hole collector 7.
В коллектор 7 сжиженный газ поступает из установки 8 повторного сжижени по трубопроводу 9.Into the manifold 7, the liquefied gas is supplied from the re-liquefaction unit 8 via pipeline 9.
Дл получени пленки используют сжиженный газ, хранимый в резервуаре.To obtain a film, liquefied gas stored in a tank is used.
Предмет изобретени Subject invention
Способ защиты от разрушени стен льдогрунтового резервуара дл хранени сжиженного газа путем смачивани внутренней поверхности резервуара сжиженным газом, отличающийс тем, что, с целью защиты стенок от сублимационного разрушени , смачивание производ т хранимым сжиженным газом , который подают по периметру стен до получени сплошной пленки,The method of protection against the destruction of the walls of an ice-ground tank for storing liquefied gas by wetting the inner surface of the tank with liquefied gas, characterized in that, in order to protect the walls from sublimation destruction, the wetting is performed by stored liquefied gas, which is served around the perimeter of the walls until a continuous film is obtained,
