Description

Technical Field

[0001] The utility model relates to the technical field of deaerators, in particular to a deaerator with easy replacement components. Background Art

[0002] The deaerator is an alternative to the spray-fill deaerator and is one of Huabo's latest thermal deaerators. The principle of a rotary film deaerator is that feed water is ejected spirally through a membrane tube at a specific angle, exchanging heat with the heated steam to remove oxygen. The feed water is heated to the saturation temperature corresponding to the deaerator's operating pressure, removing dissolved oxygen and other gases from the feed water, thereby preventing and reducing corrosion of the boiler feed water pipes, economizers, and other ancillary equipment. The deaerator is primarily composed of a deaerator tower head and a deaerator water tank, as well as pipes and external components. The main component of the deaerator is the outer shell, steam-water separator, a new rotary film deaerator, a water grate, and a heat storage filler liquid-steam network.

[0003] The Chinese patent publication number is CN216203280U, and the authorization announcement date is April 5, 2022. It is about a deaerator.
