AI Technical Summary

Technical Problem

The filter bag frame of a bag pulse dust collector accumulates static electricity due to friction, which poses a risk of combustion and explosion. Current technology lacks a design to directly conduct static electricity, thus creating a safety hazard.

Method used

Conductive blocks and grounding wires are integrated into the bag frame of the pulse dust collector. Static electricity is discharged in real time through the path of frame → cover → grounding wire → earth. Copper braided grounding wire and galvanized flat iron are used to ensure low impedance grounding. The conductive blocks are connected to the frame to prevent voltage accumulation.

Benefits of technology

It achieves an electrostatic discharge time of less than 0.1 seconds, reduces the frame voltage from 15kV to below 0.3kV, avoids sparks causing explosions, reduces safety risks, and costs only 5%-10% of explosion-proof retrofitting. It is suitable for various types of bag pulse dust collectors.
