　　The installation sequence of bubble cap tray includes the riser, bubble cap, weir, and downcomer trays

　　The tray is the main component in a plate tower, used to allow two fluids to come into close contact and exchange substances between the two phases, in order to achieve the separation of liquid or gas mixture components. Due to the variety of tray types, today I will mainly introduce the commonly used bubble cap tray. The main structure of the bubble cap tray includes the riser, bubble cap, weir, and downcomer. The riser is the main feature of the bubble cap tray, which serves as a channel for gas to enter the previous tray from the lower tray and also prevents liquid from leaking into the next tray.

　　1. Support point measurement
