AI Technical Summary

Technical Problem

In biomass boiler flue gas dust removal devices, the dust collector bags are prone to denting and collapsing, and the accumulation of dust leads to a decrease in efficiency. The transmission components are easily contaminated by dust and have a shortened lifespan, making it difficult to achieve stable and efficient dust removal.

Method used

The dust collector bag is radially supported by a first and a second shaking ring. The flue gas to be treated drives the impeller to rotate and drive the bidirectional threaded screw. Automatic dust removal is achieved through the impact unit and guide plate. A dustproof unit is set up for dynamic sealing protection to prevent dust from contaminating the transmission components.

Benefits of technology

It effectively prevents dust collector bags from denting, improves dust removal efficiency, reduces the frequency of downtime for cleaning, extends the life of transmission components, and enables continuous and stable operation of the device and efficient dust removal.
