Structure of composite tray plates

Let me introduce myself first. A composite single-flow bubble tray distillation column consists of a heating vessel, a tower top, a column body, connecting pipes, and several trays. What sets it apart is that the trays are of the composite single-flow bubble tray type. Such trays are composed of a main vapor-liquid contact element, a liquid dropping element, a liquid receiving element, and a channel bottom plate. The main vapor-liquid contact element is located in the middle of the tray; it is formed by arranging several S-shaped elements along with two incomplete S-shaped elements in a specific pattern and sequence, with each element covering the one before it, and the ends of this arrangement being welded to the end seal plates. The incomplete S-shaped element at the front of the main vapor-liquid contact element is connected to the liquid dropping element, while the incomplete S-shaped element at the back is connected to the liquid receiving element. The end seal plates on both sides of the main vapor-liquid contact element are connected to the channel bottom plate. The tray itself is secured to the inner wall of the column body by the sides of the liquid dropping element, the liquid receiving element, and the outer edge of the channel bottom plate.
