A pulse air accelerating dust collector which improves space utilization and reduces manufacturing cost of the dust collector by allowing injection of pulse air to obtain acceleration power through an injector including a venturi part, thereby obtaining substantially strong cleaning power of dust adhered onto outer surfaces of bag filters is provided. In an industrial dust collecting equipment comprising: a housing having a suction port and an exhaust port; a plurality of bag filters installed in the housing; and bag filter cleaning means having a plurality of injectors(70) installed on a nozzle pipe(60) correspondingly to the bag filters, a pulse air accelerating dust collector is characterized in that the bag filter cleaning means has the injectors comprising: a circular pipe type distributing and injecting part(71) which has an inflow port(711) formed in an upper portion thereof and connected to the nozzle pipe to receive compressed air, and an injection opening nozzle part(713) formed in a lower portion thereof; a venturi part(73) slantly formed such that diameter of the venturi part is gradually reduced from a lower side of the distributing and injecting part to the inner side of the distributing and injecting part; and a vertical part(75) connected to a lower side from the venturi part.
