The invention provides a pneumatic transport shipment equipment with dust-removing and pressure-releasing cavity, comprising a feed delivery pipe, a pneumatic actuator and dust removing equipment; wherein, the pneumatic actuator is connected with the feed delivery pipe, and the dust removing equipment is near to the output end of the feed delivery pipe. The dust removing equipment comprises a cover body, a filtering apparatus and a getter device; wherein, the inner hollow cavity of the cover body comprises a filtering cavity above the output end and the pressure-releasing cavity below the output end. In the shipment equipment of the invention, the lower part of the dust removing equipment is provided with the pressure-releasing cavity, and the getter device such as a draught fan, and the like, can generate effective subpressure in the limited pressure-releasing cavity; and the pressure-releasing cavity consistently keeps the subpressure effect when materials are transported, in the process of transport, when being transported to a discharge hole, the materials can not directly enter into the open space of the cabin of an open ship but firstly are completely decompressed in the pressure-releasing cavity then fall into the cabin after the generated throw dirt is absorbed by the getter device, therefore, the shipment equipment can realize dustless fast shipment.
