A new type filter cartridge dust collector with conical structure was studied. The filtration material characteristics, dust load, filtration velocity, jetting pressure, dust cleaning method and the structural parameters of the filter cartridge dust collector were considered as the evaluation factors, a hierarchical structure model for the performance evaluation factor analysis of a new filter canister dust collector was established based on the analytic hierarchy process (AHP). Then the judgment matrixes of all hierarchies were set up using the Delphi method, and finally the weights of the main performance parameters for the new filter cartridge dust collector, such as filtration efficiency, pressure drop, dust cleaning performance, air volume and economy were analyzed. The results showed that the weight of the evaluation factors of the new filter cartridge dust collector is as follows: filtration material characteristics?the structural parameters of the new type filter cartridge dust collector?dust load?filtration velocity?dust cleaning method?jetting pressure, and the relative weight of the performance parameters affecting the selection of the new filter cartridge dust collector is as follows: filtration efficiency?economy?pressure drop?dust cleaning performance?air volume.
