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.
