Abstract: Low-pressure pulse-jet bag filter has been widely used in various industries with high cleaning strength and high cleaning efficiency. The Conventional wisdom says that 6m long bag as long type.Therefore bag filter is limited to traditional idea over the years. Based on the experimental study, CFD simulation and verification with the realistic condition of urgent demand, super long bag and low -pressure pulse-jet bag filter has been applied, and achieved favourable performance. It will help promote the development and application of low -pressure pulse-jet bag filter further. The new bag filter depends on gas flow-guide devices usage and integral transportation and installation. With the breakthrough of traditional concept, it will be used widely.
