AI Technical Summary

Technical Problem

Existing particulate matter filtration and separation devices for gas turbine flue gas suffer from uneven flue gas distribution, which affects filtration and separation efficiency.

Method used

The motor drives the belt assembly and cam assembly to move the connecting plate, enabling the vertical movement and shaking of the filter bag. This ensures that the flue gas is evenly distributed within the filter box, and the shaking amplitude is increased by the connecting structure at the bottom of the filter bag to prevent particulate matter from adhering.

Benefits of technology

It improves the filtration and separation efficiency of particulate matter in flue gas, extends the service life of filter bags, avoids the accumulation of particulate matter in the middle of the filter bags, and enhances the dust removal effect.
