Hybrid is a new type of composite dust collector. It adopts the principles of electrostatic precipitator and bag dust collector. It overcomes the shortcomings of single function dust collector. For the working conditions of high inlet concentration, high specific resistance of dust and high discharge requirement at outlet, it has the characteristics of low resistance of filter bag, long service life and long ash cleaning cycle compared with pure bag dust collector in later operation. It takes up smaller area, has relatively lower one-time investment cost, and achieves better synergistic removal of heavy metal pollution than ESP.
