Description

Technical Field

[0001] The present invention relates to the technical field of gas treatment, and in particular to a low-carbon ultra-clean emission device for kiln flue gas. Background Art

[0002] In industrial production, kilns are essential thermal equipment, widely used in industries such as cement, glass, and steel. However, during operation, kilns generate large amounts of flue gas containing pollutants such as dust, nitrogen oxides, and sulfides. Direct discharge of these flue gases can cause severe atmospheric pollution, exacerbating environmental problems such as smog and acid rain, while also failing to comply with increasingly stringent environmental regulations.

[0003] Currently, existing kiln flue gas treatment equipment on the market suffers from numerous deficiencies. For example, traditional dust removal equipment often utilizes a fixed filter element. After long-term use, a large amount of dust easily accumulates on the filter element surface, resulting in reduced filtration efficiency. This necessitates frequent downtime for manual cleaning or filter element replacement, which not only impacts production efficiency but also increases operational costs. While some equipment is equipped with dust cleaning devices, these devices are ineffective, making it difficult to completely remove stubborn dust from the filter element surface. Furthermore, the cleaning process can easily damage the filter element, shortening its service life. Summary of the Invention
