Abstract

FIELD: fluid engineering; systems for saturating liquids with gas, gas compression or removal, such as evacuation systems of steam turbines. SUBSTANCE: gas-and-liquid ejector has coaxially mounted active nozzle, mixing chamber, diffuser, intake chamber with passive-medium supply pipe, active-medium supply pipe. Pipe interior communicates with mixing chamber on its inlet section through transfer ducts provided with control nozzles mounted inside mixing chamber and with regulating throttles. Transfer ducts may be made to communicate with mixing chamber at its outlet section through taps also provided with control nozzles mounted inside mixing chamber and with regulating throttles. Control nozzles are arranged symmetrically about its axis for changing their inclination angle relative to mentioned axis. EFFECT: intensified spraying of active liquid jet to produce uniform gas-and-liquid flow on smaller length of mixing chamber which reduces its axial dimensions; reduced friction loss due to shorter length of chamber which improves efficiency of ejector; provision for initiating mixing zone and stabilizing its position thus improving operational stability, reliability, and efficiency; efficient operation under variable conditions.

Изобретение относится к струйной технике и может быть использовано в системах насыщения жидкости газом, сжатия газов или их удаления, например в системах вакуумирования паровых турбин. Задача: создание жидкостно-газового эжектора, обеспечивающего интенсификацию процесса дробления струи активной жидкости и получения однородного жидкостно-газового потока на меньшей длине камеры смешения, что приводит к уменьшению осевых габаритов камеры смешения, уменьшению потерь на трение за счет снижения длины камеры смешения и, следовательно, к повышению КПД эжектора. Сущность: жидкостно-газовый эжектор содержит соосно установленные активное сопло, камеру смешения, диффузор, приемную камеру с патрубком подвода пассивной среды, патрубок подвода активной среды. Полость патрубка сообщена с камерой смешения на ее входном участке посредством перепускных каналов, снабженных соплами управления, установленными в корпусе камеры смешения, и регулирующими дросселями. Перепускные каналы могут быть сообщены с камерой смешения на ее выходном участке посредством отводов, также снабженных соплами управления, установленными в корпусе камеры смешения, и регулирующими дросселями. Сопла управления установлены в корпусе камеры смешения симметрично вокруг оси ее с возможностью изменения их углов наклона относительно указанной оси.The invention relates to inkjet technology and can be used in systems for saturating a liquid with a gas, compressing gases or removing them, for example, in vacuum systems for steam turbines. Objective: the creation of a liquid-gas ejector, which intensifies the process of crushing a jet of active liquid and obtain a homogeneous liquid-gas stream over a smaller length of the mixing chamber, which leads to a decrease in the axial dimensions of the mixing chamber, reducing friction losses by reducing the length of the mixing chamber and, therefore to increase the efficiency of the ejector. SUBSTANCE: liquid-gas ejector contains coaxially mounted active nozzle, mixing chamber, diffuser, receiving chamber with passive medium supply pipe, active medium supply pipe. The cavity of the pipe is in communication with the mixing chamber at its inlet by means of bypass channels equipped with control nozzles installed in the housing of the mixing chamber and regulating chokes. The bypass channels can be communicated with the mixing chamber at its outlet section by taps also equipped with control nozzles installed in the housing of the mixing chamber and control chokes. The control nozzles are installed in the housing of the mixing chamber symmetrically around its axis with the possibility of changing their tilt angles relative to the specified axis.
