Description
Изобретение относитс к парогенераторам, преимущественно дл атомных электростанций .The invention relates to steam generators, mainly for nuclear power plants.
Известны парогенераторы, содержащие нагревательные трубы, заключенные в открытый снизу сосзД, на крышке которого установлены нароотделители и камера, в последнюю из сосуда поступает паровод на смесь, распредел юща с затем при помощи радиальных трубопроводов по пароотделител м, нижп часть которых снабл :ена дренажными отверсти ми, расположенными ниже уровн воды в парогенераторе 1.Steam generators are known that contain heating pipes enclosed in an open bottom of the vessel, on the lid of which the separators and chamber are installed. located below the water level in the steam generator 1.
Недостатками описанного парогенератора вл етс сложность конструкции и иизкое качество сепарации пара при пониженном уровне воды вследствие захвата его в опускной участок парогенератора.The disadvantages of the described steam generator are the complexity of the design and the low quality of steam separation at a reduced water level due to its capture in the downstream section of the steam generator.
Известны также парогенераторы, содержащие нагревательные трубы, заключенные в открытый снизу сосуд, на крыщке которого установлены пароотделители и кольцевое перепускное ребро, охватывающее часть пароотделителей , а его верхн кромка расположена ниже водосливного выпуска пароотделителей (2.Also known are steam generators containing heating pipes enclosed in an open bottom vessel, on the lid of which steam separators and an annular bypass rib are mounted, covering part of the steam separators, and its upper edge is located below the overflow outlet of the steam separators (2.
Недостатком указанного парогенератора вл етс низкое качество сепарации пара при пониженном уровне воды вследствие захвата его в опускной участок парогенератора.The disadvantage of this steam generator is the low quality of steam separation at low water levels due to its capture in the descending part of the steam generator.
С целью улучщени сепарации пара при понил енном уровне воды в парогенераторе в предлагаемом парогенераторе кольцевое ребро охватывает все пароотделители, снабженоIn order to improve the separation of steam at a reduced water level in the steam generator in the proposed steam generator, the annular rib covers all steam traps, is equipped with
дренажными отверсти ми в нижней части, а его верхн кромка расположена вьпие водосливного выпуска нароотделителей.the drainage holes are in the lower part, and its upper edge is located at the outlet of the water separators.
На чертеже схематически изображен продольный разрез парогенератора.The drawing shows schematically a longitudinal section of a steam generator.
Парогенератор содержит корпус 1, нагревательные трубы 2, заключенные в открытый снизу сосуд 3, на крыщке 4 которого установлены пароотделителн 5 и кольцевое перепускное ребро 6, снабженное в нижней частиThe steam generator includes a housing 1, heating pipes 2, enclosed in an open bottom vessel 3, on the lid 4 of which a steam separator 5 is installed and an annular bypass rib 6 provided in the lower part
дренажными отверсти ми 7, а его верхн кромка 8 расположена выще водосливного выпуска 9 пароотделителей 5.the drainage holes 7, and its upper edge 8 is located above the overflow outlet 9 of the steam trap 5.
Парогенератор работает следующим образом .The steam generator works as follows.
Греющий теплоноситель проходит по нагревательным трубам 2 и отдает тепло воде, кип щей в межтрубном пространстве. Образовавша с паровод на смесь ноступает в пароотделители 5, из которых пар направл етс к потребителю, а вода выходит через водосливные выпуски 9 и заполн ет ограниченное кольцевым перепускным ребром 6 и крыщкой 4 нространство, из которого через дренажныеThe heating coolant passes through the heating pipes 2 and gives off heat to the water boiling in the annular space. Formed from the steam pipe to the mixture enters the steam trap 5, of which steam is sent to the consumer, and the water comes out through the spillway outlets 9 and fills the space limited by the annular bypass rib 6 and the lid 4
отверсти 7 и верхнюю кромку 8 поступает вholes 7 and the upper edge 8 enters
