[Abstract]:In this paper, the pressure monitoring system of pressurized liquid curtain bed is designed and built. By adjusting the gas-liquid velocity and working pressure in the pressurized liquid curtain bed, the flow characteristics in the pressurized liquid curtain bed were studied, and the variation of pressure fluctuation and resistance coefficient were analyzed. Based on the experimental data and theoretical analysis, the variation rules of pressure differential pulsation strength and resistance coefficient under different gas-liquid velocity and working pressure are obtained, and the optimal working parameters are analyzed according to the principle of gas-liquid absorption reaction in flue gas desulfurization. This study can provide an important design reference for the industrial application of pressurized liquid-curtain bed gas-liquid reaction system.
