How to solve the problem of sticky dust in bag filters?

Adhesive dust is characterized by a tendency to form heavy deposits and accumulations on the surface of filter bags, which undoubtedly poses significant challenges to the normal operation of baghouse dust collectors. To address this issue effectively, we should adopt targeted treatment measures based on the principle of adsorption. Specifically, an appropriate amount of porous powder can be added into the system pipelines. Thanks to their porous structure, these powders have an extremely large surface area, which provides an ideal adsorption site for dust particles. As adhesive dust passes through the powders, it can be effectively adsorbed on their surfaces. In this way, the problem of heavy adhesion and accumulation of adhesive dust on filter bag surfaces is effectively resolved.

In addition, this treatment method delivers remarkable practical results. For instance, refractory plants have successfully purified asphalt flue gas using dolomite powder, and aluminum plants adsorb asphalt and hydrogen oxide with alumina. In the asphalt concrete workshops of road construction companies, limestone powder has also demonstrated high-efficiency adsorption performance, with an adsorption efficiency of over 90%. These practical cases fully prove the effectiveness of this approach for controlling adhesive dust in baghouse dust collectors. In practical applications, enterprises can select suitable powders and treatment methods based on their specific operational conditions to achieve the optimal treatment effect.
