Abstract

The invention relates to the technical field of steam turbine air extractors, and discloses a multistage jet type air extractor used for a steam turbine. The multistage jet type air extractor comprises a main air extractor and an auxiliary air extractor. The auxiliary air extractor is installed in the main air extractor. An auxiliary exhaust port of the auxiliary air extractor communicates with the outside world. An auxiliary air inlet of the auxiliary air extractor is arranged in the manner that the auxiliary air inlet of the auxiliary air extractor faces a main exhaust port of the main air extractor. According to the multistage jet type air extractor used for the steam turbine, the auxiliary air extractor is arranged in the main air extractor, the inner space of the main air extractor issufficiently utilized, and the problem that the space of the part of a steam inlet of the main air extractor cannot be effectively utilized is solved.

Description

technical field [0001] The invention relates to the technical field of steam turbine air extractors, in particular to a multi-stage jet air extractor for steam turbines. Background technique [0002] The function of the air extractor is to continuously extract the air leaked into the condenser to maintain a high vacuum in the condenser, so the working efficiency of the air extractor has a great influence on the condenser. [0003] In the prior art, in order to effectively extract non-condensable gases, the air extractors are usually designed as a multi-stage structure arranged in series. Since the jet air extractor needs to achieve air extraction through jet negative pressure, the steam flow rate in the working process is high. Heat pipe. It can be seen that there is a certain waste in the internal space of the serial air extractor. Contents of the invention [0004] An embodiment of the present invention provides a multi-stage jet air extractor for a steam turbine, whi...
