The utility model discloses a theory of operation does:
the gas and liquid phases enter the gas and liquid distribution tray from top to bottom, wherein the liquid phase drips onto the mounting plate 100 and forms a static liquid level. The gas phase enters the gas-liquid distributor 200 through the gas phase inlet 11. Since the sectional area of the gas phase inlet 11 is smaller than that of the gas-liquid mixing chamber 2, the flow rate of the gas phase in the gas phase passage 1 is greater than that in the outside and the gas-liquid mixing chamber 2, and a pressure difference is generated between the inside and the outside of the gas-liquid distributor 200 under the action of the venturi effect. This pressure difference provides the main driving force for the liquid phase to flow into the gas-liquid mixing chamber 2 through the liquid phase inlet 21. The liquid phase above the liquid phase inlet 21 provides a secondary driving force for the liquid phase to flow into the gas-liquid mixing chamber 2 through the liquid phase inlet 21 due to the hydraulic pressure of the liquid phase due to the hydrostatic height. Then, the gas-liquid mixture flows downwards through the outlet channel 3, the contraction section 31 plays a role in acceleration, and the diffusion section 32 can enable the gas-liquid mixture to generate speed and pressure changes, so that atomization of the gas-liquid mixture is achieved. Finally, the atomized gas-liquid mixture is uniformly sprayed on the catalyst bed layer below the outlet channel 3.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
