High efficiency low resistance cascade multiple pipe dust remover

The utility model relates to a high efficiency and low resistance step type dust remover with multiple pipes, which belongs to the field of environmental protection. The high efficiency and low resistance step type dust remover with multiple pipes s characterized in that the trace of the contour line of an inlet spiral casing of each cyclone adopts constant a speed spiral line. The high efficiency and low resistance step type dust remover with multiple pipes has the purposes that spiral flow and resistance in a cylinder are reduced, and the inlet flow speed of each cyclone is increased. Simultaneously, each cyclone adopts the arrangement with two step types, and the dust discharging space of each is provided with a spraying device for catching dust and discharging the dust. The high efficiency and low resistance step type dust remover with multiple pipe overcomes the series flow among the cyclones. After the dust is concreted, the small dust can directly enter a clinker removing machine with a boiler through a lower sealing pipeline of a dust bucket, and the secondary pollution of the small dust is reduced.
