Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, in particular to an electrolytic aluminum desulfurization device. Background Art

[0002] The flue gas generated by electrolytic aluminum is only allowed to be discharged after desulfurization. The electrolytic aluminum desulfurization device is a device used to remove harmful substances such as sulfur dioxide from the flue gas during the electrolytic aluminum production process. Desulfurizers are usually used to desulfurize the flue gas.

[0003] Existing electrolytic aluminum desulfurization equipment usually adopts a direct spraying method to allow the desulfurizer to contact the flue gas for desulfurization. However, the contact time between the flue gas and the desulfurizer is short, which may lead to incomplete flue gas desulfurization and environmental pollution after discharge.

[0004] Therefore, the above-mentioned existing electrolytic aluminum desulfurization devices usually adopt a direct spraying method to allow the desulfurizer to contact the flue gas for desulfurization, but the contact time between the flue gas and the desulfurizer is short, which may lead to incomplete desulfurization of the flue gas and pollute the environment after discharge. An electrolytic aluminum desulfurization device can be designed to form a tortuous flue gas channel in the desulfurization device through multiple groups of guide plates, slowing down the speed of the flue gas passing through, so that the flue gas can fully contact the desulfurizer, thereby improving the desulfurization effect.

Multiple groups of guide plates 101 are staggered up and down to form a tortuous flue, which increases the time for the flue gas to pass through.
