The Positive Pressure Dense Phase Pneumatic Conveying System has the features of simple system, flexible layout, reliable operation, high degree of automation, low system investment, high feed gas ratio, low flow rate, small maintenance workload and low annual operating cost. The system includes feeding device, sending warehouse pump, pipelines, valves, reservoir top dedusting device, bottom reservoir gasification device, bottom unloading device, power source, program control device and so on. The warehouse pump has strong structure, good sealing performance, large conveying capacity, long conveying distance, and can meet the requirements of production. The structure is simple. Except for compressed air, there are no transmission parts that come in contact with the materials, so the failure is small and the operation reliability is good.
