Description
Известные газовые эжекторы содержат сопло дл высоконапорпого газа, приемную и смесительную камеры и диффузор.Known gas ejectors contain a nozzle for high-pressure gas, receiving and mixing chambers and a diffuser.
Дл предотвращени обмерзани рабочих поверхностей в известных эжекторах в газовый поток ввод т антпфризы, например метапол и т. п., или осуш,ествл ют подогрев газа до эжектора, или примен ют обогрев последнего в местах интенсивного образовани снегообразной массы.To prevent frosting of working surfaces in known ejectors, entfreezes are introduced into the gas flow, for example, metapol, etc., or dried, the gas is heated to the ejector, or the latter is heated in places with intensive snow-like mass.
В предложенном газовом эжекторе рабочие поверхности покрыты защитпым несмачивающимс материалом, например пластмассой.In the gas ejector according to the invention, the working surfaces are covered with protective non-wetting material, for example plastic.
Такое выполнение эжектора позвол ет предот фап;ать обмерзапие его рабочих поверхностей при наименьших материальных и эксплуатацпонных затратах и обеспечивает устойчивую работу эжектора.Such an implementation of the ejector allows to prevent frosting of its working surfaces at the lowest material and operational costs and ensures stable operation of the ejector.
Па чертеже схематически изображен описываемый эжектор.Pa drawing shows schematically described the ejector.
Он содержит сопло / дл высокопаиорного газа, приемпую 2 и смесительпую 3 камеры и диффузор 4. Рабочие поверхности эжектора покрыты защитным материалом 5, нанример пластмассой, не смачивающимс пластовой влагой в процессе ее конденсации. Эжектор устанавлнваетс с уклоном в направлении газового потока (при возможности-вертикально ) с тем, чтобы по мере образовани жидких гидратов в приемной камере последние скатывались к камере смешени и уносились газовым потоком в трубопровод. Кристаллы гидрата, намерзающие на стенках камеры смешени , также будут уноситьс газовым потоком вследствие низкой адгезии их к покрытию . В трубопроводе гидраты разлагаютс , так как отсутствуют услови , поддерживающие их существование.It contains a nozzle / dl for high-vaporizer gas, receiving 2 and mixing 3 chambers and a diffuser 4. The working surfaces of the ejector are covered with protective material 5, such as plastic, which is not wetted by formation moisture during its condensation. The ejector is installed with a slope in the direction of the gas flow (if possible, vertically) so that as the formation of liquid hydrates in the receiving chamber, the latter are rolled to the mixing chamber and carried away by the gas flow into the pipeline. Hydrate crystals that freeze on the walls of the mixing chamber will also be carried away by the gas flow due to their low adhesion to the coating. In the pipeline, hydrates decompose because there are no conditions supporting their existence.
Следовательно, в описываемом эжекторе устранены локальные услови , поддерживающие процесс обмерзани рабочих поверхпостей , что обеспечивает устойчивую работу эжектора.Consequently, in the described ejector local conditions are eliminated, supporting the process of frosting of working surfaces, which ensures stable operation of the ejector.
Кроме того, покрытие будет защищать рабочие поверхности эжектора от коррозии и эрозии и нозволит исключить примепепие высоколегированных сталей дл изготовлени сопла и камеры смешени .In addition, the coating will protect the working surfaces of the ejector from corrosion and erosion and will prevent the use of high alloy steels for the manufacture of the nozzle and the mixing chamber.
