AI Technical Summary

Technical Problem

Traditional baghouse dust collectors suffer from problems in carbon black production and downstream applications, such as rapid energy decay during cleaning, large cleaning blind spots, short filter bag life, low energy efficiency, lack of effective means to handle sticky dust, and no technical solution integrating electromagnetic force drive with filter bag cleaning process has been found.

Method used

It adopts a magnetically driven lifting system combined with a composite dust removal mechanism of radial expansion of airbags and pulse airflow backflushing, combined with an intelligent differential pressure management system and energy recovery design. It achieves precise lifting through the repulsive effect between electromagnets and permanent magnets, integrates multi-point pressure sensors for real-time monitoring and automatic dust removal, and is equipped with pulse valves for segmented pressurization control.

Benefits of technology

It achieves a high-efficiency dust removal efficiency of over 40%, extends filter bag life to over 3 years, and achieves a comprehensive system energy efficiency ratio of 85%, making it particularly suitable for the purification of high-concentration sticky carbon black dust.
