To suck at least one of liquid and solid with air, separate and exhaust the air by centrifugal action, and recover the liquid and solid.

A recovery apparatus 11 is equipped with a cylindrical airtight container 15 and a suction portion 14 for generating suction force utilizing compressed air. The airtight container 15 is provided with an exhaustion pipe 22 and an introduction pipe 20 for introducing the sucked air or the like so that the sucked air flows therein along the inside of the airtight container 15. The introduction pipe 20 and the suction portion 14 are connected through a hose 21. A cover body 15c of the airtight container 15 is fixed with a guide member 26 for guiding the compressed air introduced from the introduction pipe 20 so that the compressed air flows into the inside of a guide portion from outside through a gap between the guide portion and the inner surface of the airtight container 15. The guide member 26 includes the cylindrical guide portion having the upper end fixed to the cover body 15c with the exhaustion pipe 22 inside and flared downward. The suction portion 14 is connected to a suction nozzle 19 on the suction side.
