Steam-water separation equipment

Abstract

Steam-water separation equipment comprises a barrel with a steam-water separation cavity. The steam-water separation cavity comprises a flow distributor and a steam-water separator which communicate with each other in sequence. A steam inlet communicating with the flow distributor and a steam outlet communicating with the steam-water separator are formed in the side wall of the barrel. The steam-water separator comprises a plurality of obliquely arranged steam-water separation units, the steam-water separation units are arranged longitudinally, and a connecting plate is connected between the end portions of every two adjacent steam-water separation units. By obliquely arranging the steam-water separation units, the contact area of steam and the steam-water separation units is effectively enlarged, and the steam-water separation efficiency is improved. Besides, as the steam-water separation units are disposed layer by layer longitudinally, the problem that the height of a single steam-water separation unit is limited is solved, and meanwhile by adoption of the layering arrangement mode, the steam entry amount and the drainage volume of each steam-water separation unit can be reduced, and reliable running of the steam-water separation units is ensured.

Description

technical field [0001] The invention relates to the technical field of nuclear power engineering, in particular to a steam-water separation device. Background technique [0002] In a nuclear power plant, the steam entering the steam turbine is saturated steam, so the humidity of the steam discharged from the high-pressure cylinder after doing work is relatively high. However, a series of equipment located behind the high-pressure cylinder has high requirements on dryness, so it is necessary to reduce the humidity of the steam discharged from the high-pressure cylinder. In order to reduce the humidity of the steam, the steam-water separation equipment is used to separate the steam from the wet steam, so as to improve the dryness of the wet steam. [0003] In the existing technology, a simple steam-water separation device is directly installed in the pipeline. The separation efficiency is not high, and the dryness required by the follow-up equipment of the high-pressure cylin...

Problems solved by technology

[0003] In the existing technology, a simple steam-water separation device is directly installed in the pipeline. The separation efficiency is not high, and the dryness required by the follow-up equipment of the high-pressure cylinder cannot be achieved, which seriously affects the safety or efficiency of the equipment.
