Is the tray a movable part or a fixed part?
The tray is fixed on the support beam inside the tower. Some of the gas-liquid contact elements on the tray are movable, such as float valves and bubble caps.； Some cannot move, such as tongue-fixed tower plates.
The parts connected in the tower by bolts are movable parts, and the parts connected in the tower by welding are fixed parts.
The tray is a fixed part, and some parts inside the tower are movable parts, such as float valves and bubble caps.
Many trays are connected to the tray ring seats through bolts, and the tower ring seats are generally welded to the tower body. Slightly larger trays have a removable channel plate in the middle for maintenance or inspection, and small-diameter trays can also be disassembled in pieces. The advantage of the tray being fixed on the ring seat through bolts is that it can be easily replaced, for example, by replacing it with various high-throughput and efficient trays to increase the processing load. During operation, the tray body should be a fixed part, and there may be no movable parts (such as sieve plate trays) or movable parts (such as float valve trays) on it.
