AI Technical Summary
The existing solid valve body is insufficient in gas-phase guided, resulting in low mass transfer efficiency.
An anti-blocking valve for chemical tower trays is designed. By setting up a gas raising hole and a multi-layer shielding mechanism on the tower plate, the gas phase diffuses upward from the air raising hole, passes through the multi-layer baffle in sequence, and makes full contact with the liquid phase at the upper end of the tower plate.
It effectively increases the contact area between the gas phase and the liquid phase and improves the mass transfer efficiency.
