Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a tail gas treatment tower. Background Art

[0002] The absorption tower is a device that realizes the absorption operation. The flow of gas and liquid in the tower can be countercurrent or cocurrent. Countercurrent operation is usually adopted. The absorbent is added at the top of the tower and flows from top to bottom, contacting with the gas flowing from bottom to top. The liquid that absorbs the absorbent is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower. During the use of boilers or incinerators, exhaust gas treatment towers are required to treat and discharge exhaust gas to ensure that pollution to the environment is reduced.

[0003] Existing boilers and incinerators use a variety of combustion materials to obtain heat during use, and a large amount of high-temperature harmful flue gas will be generated during the combustion process. Therefore, when using boilers and incinerators, they are equipped with tail gas treatment towers to treat and discharge the exhaust gas. Existing tail gas treatment towers usually use spray towers to treat tail gas, but when spraying, the nozzles of existing spray towers are installed on the top of the tower, resulting in insufficient contact between the spray liquid and the tail gas, resulting in poor tail gas washing effect, and the inability to effectively cool down, so that part of the high-temperature flue gas is directly discharged, causing the surrounding environment to be polluted. To this end, we propose a tail gas treatment tower. Utility Model Content
