Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment equipment, in particular to a desulfurization tower and a flow guide device thereof. Background Art

[0002] A desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. There are several types of desulfurization towers, such as packed towers, air spray towers and plate towers. The commonly used type is a packed tower, which has spraying, mist capture and other devices. At present, guide vanes are fixed at the flue gas inlet of a dry desulfurization tower or a semi-dry desulfurization tower to improve the airflow in the flue and reduce resistance.

[0003] However, most of the desulfurization tower guide devices in the prior art reduce the ventilation volume by rotating blades and adjusting the angle between the ventilation pipe and the blades to prevent the gas in the desulfurization tower from flowing back and bringing back dust. However, the exhaust gas in the ventilation pipe will also retain a certain amount of dust. After the airflow decreases, the dust will fall and accumulate on the surface of the blades. After long-term use, it will gradually block the pipe and the effect of adjusting the air volume will be greatly reduced. In order to solve the above problems, we propose a desulfurization tower and its guide device. Utility Model Content
