TECHNICAL FIELD

[0001] The application belongs to the technical field of waste gas treatment, and particularly relates to a filtering device for treating sulfuration gas. BACKGROUND

[0002] Sulfuration gas contains a large amount of sulfides and dust, which can pollute the environment and need to be filtered before being discharged. At present, the desulfurization method generally adopts a chemical reaction between an absorbent and sulfides in the flue gas. The commonly used absorbent is limestone, and the main component of the limestone is calcium hydroxide. When the limestone contacts with sulfur dioxide in the flue gas, a chemical reaction occurs to generate calcium sulfate, and heat is released at the same time, thereby completing the desulfurization of sulfur dioxide in the flue gas.

[0003] However, the above-mentioned technology still has the following problems: the contact time between the flue gas and the absorbent is short during the flow of the flue gas, which leads to insufficient chemical reaction and incomplete desulfurization. In addition, the filter plate of the existing filtering device is not convenient to clean.
