The tail gas is discharged from the top of the bubbling absorption tower after being absorbed by the bubbling absorption tower, and is directly discharged into the atmosphere through an automatic regulating valve, and the tail gas discharged in the method is often entrained with water. This portion of the water tends to be acidic due to the nature of the bubble column and is corrosive. When the acidic water in the exhaust falls into a building or equipment, the building or equipment is corroded, resulting in damage. Burn and other conditions can be caused when the water is sprayed to a person. Therefore, the method has potential safety hazard and can cause environmental pollution. And the exhaust can be discharged with high noise, and noise pollution can be caused.
