Bubble cap column is a kind of bubble type plate column. Gas (or steam) passes through the bubble cap on the tray and contacts with the liquid on the tray in a dispersed phase. It is a kind of tower with complicated structure. The bubble cap tower is composed of tower body, bubble cover, overflow weir, downcomer and vapor-liquid inlet and outlet. The bubble cover on the tray is the main part of the tower. The seal between the tray and the tower body is made of temperature resistant and acid resistant rubber or polytetrafluoroethylene. There are two kinds of graphite bubble cover: round bubble cover and strip bubble cover: the circular bubble cover is widely used, and the strip bubble cover is generally used in the field with large liquid gas ratio.
