Technical Field

[0001] The utility model relates to the field of waste gas treatment equipment, in particular to a boiler equipment emission purification device. Background Art

[0002] During the operation of the boiler, a large amount of exhaust gas is generated, which contains harmful substances such as sulfur dioxide (SO2), nitrogen oxides (NOx), smoke, etc. If these substances are directly discharged into the atmosphere without treatment, they will have a serious impact on the environment and human health.
