What is the function of the liquid receiving tank? When is a receiving tank used?
It is also commonly referred to as a \"liquid receiving tray\"; in a plate tower, it receives the liquid that flows down from the downcomer on the upper tray, allowing the liquid to flow into the bubbling zone of that tray as horizontally as possible. The liquid receiving trays come in two structural types: flat and concave. Flat liquid receiving trays can be used with various types of materials, but the flow of material from the tray to the tower tray is not smooth enough. Concave liquid receiving trays are not suitable for materials that contain crystals or sticky substances; their advantage is that the flow of material from the tray to the tower tray is smooth. Concave liquid receiving trays are more commonly used, as they can cushion the impact of the liquid flowing down from the downcomer, reducing liquid splashing caused by such impacts; moreover, when the liquid phase reflux is low, the liquid remaining in the tray can also serve as a liquid seal.
Generally speaking, flat liquid receiving trays are suitable for various materials, but the flow of material from the tray to the tower tray is not smooth enough. Concave liquid receiving trays are not suitable for materials that contain crystals or adhering substances; their advantage is that the flow from the tray to the tower tray is smooth
To ensure a liquid seal at the outlet of the downcomer, a liquid receiving tray is installed on the tray. The liquid receiving tray comes in flat and concave types. For materials that are prone to aggregation and contain suspended solids, flat liquid receiving trays should be used to avoid the formation of dead zones on the tray plates. When the pressure drop of the liquid through the downcomer exceeds 25 mm, a concave liquid receiving tray should be used. The concave liquid receiving tray acts as a buffer for the liquid flow, facilitating uniform gas distribution, and it still maintains a good liquid seal on the tray even at low liquid levels. The depth of the concave liquid receiving tray is generally greater than 50 mm, but it must not exceed 1/3 of the plate spacing; otherwise, the plate spacing should be increased. At the end of the downcomer of the bottom tray in the tower, a liquid seal plate should be installed to ensure a liquid seal at the outlet of the downcomer.
Not bad:lol :kiss: :victory:
