This paper designs an emergency disposal device to handle the accident of acid water leakage in a chemical plant and the device uses sodium hydroxide solution as absorbent.The paper applies Aspen Plus process simulation software to simulating the decontamination process of hydrogen sulfide cleaning device in confined space and investigates the effects of liquid gas ratio,operating gas velocity,inlet concentration of hydrogen sulfide,concentration of detergent solution and specific surface area on the removal efficiency of hydrogen sulfide.Considering comprehensive decontamination effects,power consumption and other factors,the paper figures out that the liquid gas ratio should be 6~7 L/m3,the intake volume is 300 Nm3,the cleaning liquid quality fraction is not more than 4%,the packing surface should choose more than 350 m2/m3.Under optimized conditions,the emission concentration of hydrogen sulfide can be reduced to the emergency emission standard of 30 ppm.The research can provide technical support for the design and optimization of emergency disposal device for acid water leakage.
