Separator system for aircraft waste system

摘要

An aircraft separator system for removing moisture suspended in a gas of an aircraft waste system includes a waste tank and a vacuum source operatively coupled to the waste tank for creating a vacuum for drawing the waste material into the tank and drawing the gas with the moisture suspended therein out of the tank. A disposable separator housing for removing moisture suspended in the gas is disposed on the tank and removably coupled between the waste tank and the vacuum source such that the entire separator housing may be detached from the waste tank and vacuum source and discarded. A two-stage filter is contained within an interior of the housing without extending into the waste tank. The filter has at least two areas of different density mesh defining two stages including a first area located proximal to a separator inlet opening which is less dense, and a second area located proximal to a separator outlet opening which is more dense. A shroud is disposed in the waste tank at the gas outlet of the tank to minimize passage of the solids and liquids out of the gas outlet. The shroud has an annular wall with a plurality of apertures through which the gas passes in exiting the tank, and a shield attached to a lower end of the annular wall.
