Abstract
1. Устройство (100) для удаления влаги из паровой турбины, содержащее кольцо, устанавливаемое в наружном кожухе (101), в котором расположена ступень паровой турбины, и имеющее одно или более отверстий, которые проходят от внутреннего диаметра указанного кольца к его внешнему диаметру и выполнены с обеспечением прохода через них влаги и ее выведения из парового тракта турбины. ! 2. Устройство по п.1, в котором указанное кольцо расположено между рабочей лопаткой и направляющей лопаткой (104) ступени. ! 3. Устройство по п.2, дополнительно имеющее по меньшей мере одну влагоотводящую щель (108), которая проходит через наружный кожух (101) и выполнена с обеспечением прохода через нее влаги и ее выведения из парового тракта турбины. ! 4. Устройство по п.3, в котором одна влагоотводящая щель (108) расположена вровень с задней кромкой вращающейся лопатки предыдущей ступени. ! 5. Устройство по п.2, дополнительно имеющее: ! канал (113), проходящий от первого конца внутри направляющей лопатки (104) и через наружный кожух (101) ко второму концу, ! щель, расположенную на напорной стороне направляющей лопатки (104) и проточно сообщающуюся с первым концом канала (113), и ! щель, расположенную на всасывающей стороне направляющей лопатки (104) и проточно сообщающуюся с первым концом канала (113), причем указанные щели выполнены с обеспечением возможности протекания через них влаги с поверхности направляющей лопатки (104) к первому концу канала (113). ! 6. Устройство по п.1, в котором указанное кольцо содержит несколько колец, причем по меньшей мере одно кольцо расположено за рабочей лопаткой (106) предпоследней ступени перед направляющей лопаткой (104), и по меньшей мере одно 1. A device (100) for removing moisture from a steam turbine, containing a ring installed in the outer casing (101), in which the stage of the steam turbine is located, and having one or more holes that extend from the inner diameter of the specified ring to its outer diameter and designed to ensure the passage of moisture through them and its removal from the steam path of the turbine. ! 2. The device according to claim 1, in which the specified ring is located between the working vane and guide vane (104) stages. ! 3. The device according to claim 2, additionally having at least one moisture-removing slot (108), which passes through the outer casing (101) and is made with the passage of moisture through it and its removal from the steam path of the turbine. ! 4. The device according to claim 3, in which one wicking slot (108) is located flush with the trailing edge of the rotating blade of the previous stage. ! 5. The device according to claim 2, additionally having: ! channel (113) extending from the first end inside the guide vane (104) and through the outer casing (101) to the second end, ! a slot located on the pressure side of the guide vane (104) and in fluid communication with the first end of the channel (113), and ! a slot located on the suction side of the guide vane (104) and in fluid communication with the first end of the channel (113), and these slots are made to allow moisture to flow through them from the surface of the guide vane (104) to the first end of the channel (113). ! 6. The device according to claim 1, in which the specified ring contains several rings, and at least one ring is located behind the working blade (106) of the penultimate stage in front of the guide vane (104), and at least one
