Bubble Cap Tray.

The gas-liquid contacting element for bubble cap tray is bubble cap, which has round and groove-shaped structure forms. The bubble cap is installed above the chimney, and will not leak in conditions of proper installation and gas-liquid load, so the bubble cap tray is featured by stable operation and great flexibility. For structural reasons, the liquid level on the tray is relatively high, and two-phase contact is of long time. Therefore, the pressure drop is high, entrainment is increased, and the fall in the liquid level on the tray is relatively great, etc.
