Description

Technical Field

[0001] The utility model relates to the field of flue gas purification, in particular to a flue gas purification device for caustic soda production. Background Art

[0002] The flue gas generated in caustic soda production usually contains harmful gases and particulate matter. In order to meet environmental protection requirements, it is necessary to use a flue gas purification device for treatment. When purifying the flue gas, most of the time, spraying is used for purification.

[0003] When the existing spray plate sprays the flue gas, since the spraying area is fixed, the flue gas may rise from the side of the water flow and be discharged to the outside without being completely sprayed and purified, causing environmental pollution and making the flue gas purification effect poor.
