The water / air separation device (1) according to the present invention described above is mounted on a suction work vehicle as shown in FIG.
A suction working vehicle on which the water / air separation device (1) according to the present invention is mounted has a receiver tank (30) for storing a sucked object to be collected and a suction force with the receiver tank as a negative pressure. The vacuum pump (40) for generating is mounted, and the type is not particularly limited.
Examples of the suction work vehicle include a sludge suction recovery vehicle, a sediment suction recovery vehicle, a manure suction recovery vehicle, a dust suction recovery vehicle, and a waste liquid suction recovery vehicle.

本発明において、吸引作業車に搭載される真空ポンプの種類は、封入水や冷却水として内部に水を取り入れる構造を有するものであれば特に限定されず、水封式ポンプ(水環式ポンプ)、ルーツブロワ、スクリューポンプ、スパイラルポンプ等を例示することができる。   In the present invention, the type of the vacuum pump mounted on the suction working vehicle is not particularly limited as long as it has a structure for taking water into the inside as sealed water or cooling water, and a water ring pump (water ring pump). Roots blower, screw pump, spiral pump and the like can be exemplified.

本発明は、汚泥吸引回収車や土砂吸引回収車等の吸引作業車において、真空ポンプの排気中の水分を除去するための水・空気分離装置として利用されるものであり、特に小型化・軽量化された構造でありながら排気口からの水飛散を防止し得る水・空気分離装置であるため、吸引作業車に搭載するための水・空気分離装置として利用価値が高いものである。   INDUSTRIAL APPLICABILITY The present invention is used as a water / air separation device for removing moisture in the exhaust of a vacuum pump in a suction working vehicle such as a sludge suction recovery vehicle or a sediment suction recovery vehicle, and is particularly small and lightweight. Since it is a water / air separation device that can prevent scattering of water from the exhaust port even though it has a structured structure, it is highly useful as a water / air separation device for mounting on a suction work vehicle.
