Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas spray absorption, and in particular relates to a high-efficiency tail gas spray absorption device. Background Art

[0002] As one of the important operation units in the chemical industry, absorption operation is widely used in chemical, petrochemical, pharmaceutical, thermal power, cement, food processing, breeding, metal smelting, sewage treatment, plant purification and other industries. Absorption is the process of gas-liquid contact. Different components in the gas mixture have different solubility in the same liquid. One or several components with high solubility in the gas will enter the liquid phase, thereby changing the relative concentration of each component in the gas phase, that is, the mixed gas is separated and purified.

[0003] At present, conventional absorption is to add absorption liquid into the absorption tower, which is pumped into the top of the absorption tower through a circulating pump and sprayed down. The exhaust gas falls after being distributed by the packing, while the exhaust gas enters from the bottom of the absorption tower and is discharged from the discharge pipe on the top of the tower after being absorbed by the absorption liquid.

[0004] The existing spray absorption device usually needs to add drugs or absorption liquid during use. The drugs need to be stirred during the process of adding drugs. Insufficient mixing of drugs is prone to occur during stirring, resulting in waste of drugs and reducing the working efficiency of the device. At the same time, the exhaust gas needs to be filtered during emission. Most of the existing filter screens are fixed. After long-term use, the filter screens become aged or blocked and need to be replaced. If they are not replaced in time, the subsequent emissions of the device will be affected. Therefore, we need to upgrade and transform them based on the existing technology. Utility Model Content
