The invention discloses a novel cloth dust collector and belongs to the technical field of environmental protection devices. The novel cloth dust collector comprises a supporting frame (1), an inlet hole (2), a flow guide plate (3), a casing (4), a perforated plate (5), pulse-jet systems (6), a top handrail (7), a cover plate (8), a top cover face (9) and ladder stands (10), wherein the perforated plate (5) is arranged inside the upper end of the casing (4), a filter bag cage assembly is arranged on the downward side of the perforated plate (5), a plurality of pulse-jet systems (6) are arranged on the outer side of the casing (4) above the perforated plate (5), a dust inlet opening is arranged on one side of the upper end of the casing (4), a conical dust hopper is arranged at the lower end of the casing (4), the flow guide plate is arranged inside the conical dust hopper, and ladder stands (10) are arranged on the periphery of the casing (4). By the aid of a submerged pulse valve, the dust cleaning efficiency is improved, the jetting frequency is greatly reduced, and the jetting air source pressure and the device operation energy consumption can be reduced.
