Abstract
1. Способ охлаждения узлов металлургических печей, заключающийся в течении теплоносителя во всасывающем трубопроводе, коллекторе, подводящем трубопроводе, охлаждаемом узле, отводящем трубопроводе, герметичной емкости и всасе насоса под давлением ниже атмосферного, отличающийся тем, что теплоноситель подают в охлаждаемые узлы, размещенные на различных высотных отметках печи, при этом каждая группа узлов с различными высотными отметками имеет питающую емкость, каскадно-соединенную с емкостью нижней группы узлов, а во всасывающем трубопроводе создают неравномерное движение двухфазного потока теплоносителя, ускоряя поток от начальной скорости равной нулю до скорости во всасывающем трубопроводе равной 0,05-0,2 от скорости теплоносителя в охлаждаемом узле, обеспечивая объемное содержание газовой и паровой фаз на выходе из охлаждаемых узлов менее 25% от жидкой фазы.2. Установка для охлаждения узлов металлургических печей, включающая сообщающуюся с атмосферой питающую емкость с теплоносителем и с входными отверстиями всасывающих трубопроводов, размещенных ниже уровня теплоносителя, а также герметичную емкость с выходными отверстиями отводящих трубопроводов, размещенных в ее газовой полости, при этом герметичная емкость снабжена устройством для удаления газа и пара, отличающаяся тем, что уровень теплоносителя в герметичной емкости располагают ниже уровня теплоносителя нижней питающей емкости, а слив теплоносителя из герметичной емкости оборудуют гидрозатвором, и уровень отверстия гидрозатвора располагают ниже отметки расположения герметичной емкости.1. The method of cooling the nodes of metallurgical furnaces, which consists in the coolant in the suction pipe, manifold, supply pipe, cooled unit, outlet pipe, pressurized tank and pump suction under atmospheric pressure, characterized in that the coolant is supplied to the cooled units located on different elevations of the furnace, each group of nodes with different elevations has a supply tank cascaded to the capacity of the lower group of nodes, and in the suction pipe an uneven motion of a two-phase coolant flow is created, accelerating the flow from an initial velocity of zero to a speed in the suction pipe of 0.05-0.2 of the velocity of the coolant in the cooled unit, providing a volumetric content of the gas and vapor phases at the outlet of the cooled units of less than 25% from the liquid phase. 2. Installation for cooling units of metallurgical furnaces, including a supply tank connected to the atmosphere with a coolant and with inlet openings of the suction pipelines located below the level of the coolant, as well as a sealed container with outlet openings of the discharge pipelines located in its gas cavity, while the sealed container is equipped with a device for gas and steam removal, characterized in that the coolant level in the sealed container is located below the coolant level of the lower supply tank, and ive coolant from the hermetic vessel equipped with a hydraulic lock and the level of a hydraulic lock hole below the location of the hermetic vessel.
