Abstract

The invention relates to the technical field of steam power devices, and discloses an air exhaust system for a steam power device. The air exhaust system comprises a first-level main air exhaust device, a second-level main air exhaust device, a steam sealing air exhaust device and an integrated cooler, wherein a first-level cooling section, a steam sealing cooling section and a second-level cooling section, which are mutually independent, are arranged in the integrated cooler; the inlet of the first-level main air exhaust device is connected with a condenser air exhaust pipeline, and the outlet of the first-level main air exhaust device is connected with the inlet of the first-level cooling section; the inlet of the second-level main air exhaust device is connected with the outlet of the first-level cooling section, and the outlet of the second-level main air exhaust device is connected with the inlet of the second-level cooling section; the inlet of the steam sealing air exhaust device is connected with the outlet of the steam sealing cooling section, and the outlet of the steam sealing air exhaust device is connected with the inlet of the second-level cooling section; and the inlet of the steam sealing cooling section is connected with a shaft sealing air exhaust pipeline. The air exhaust system for the steam power device is convenient in intensively providing working steam and recovering condensed water of which the apparent contact angle is greater than 90 degrees, so that a space occupied for installation is greatly reduced, system pipeline complexity is lowered, and system design difficulties are lowered.

Description

technical field [0001] The invention relates to the technical field of steam power devices, in particular to an air extraction system for steam power devices. Background technique [0002] At present, ships, power stations, etc. mostly use the steam-water circulation process to provide power. The feed water in the boiler is heated to generate steam; the steam drives the turbine to rotate and output power; the steam after work is cooled into condensed water in the condenser; the condensed water is pressurized by the water pump and discharged to the boiler. This cycle provides a steady stream of power. In the steam-water cycle power plant, two kinds of air extractors, the main air extractor and the seal air extractor, are usually set. [0003] The main air extractor is an important part of the condensing equipment. Its main task is to continuously extract the air and non-condensed steam-gas mixture leaked from the vacuum system, establish and maintain a high vacuum in the co...
