To meet the evolving demands of modern industry, dust collectors have been developed that offer improved efficiency and adaptability. This chapter introduces other types of dust collectors, focusing on filter cartridge dust collectors and various compound dust collectors. First, the chapter explains the principles, structure, and performance of filter cartridge dust collectors, highlighting their high-efficiency filtration and modular design, which facilitate easy maintenance and flexible application in settings requiring fine particle control. Second, the chapter examines compound dust collectors, which combine multiple separation technologies such as mechanical, electrostatic, wet, and acoustic methods. Detailed descriptions are provided for types including electrostatic cyclone dust collectors, electrostatic bag dust collectors, electrostatic particle layer dust collectors, and several others. Application scenarios illustrate how these advanced dust collectors address complex particulate challenges in various industries by integrating hybrid filtration methods for optimal dust removal.
