PROBLEM TO BE SOLVED: To provide a mixing device capable of sufficiently centrifuging a foreign matter such as a condensate.SOLUTION: A mixing device 100 includes an outside cylinder body 110 and an inside cylinder body 120, to form a double-pipe structure. An introduction part 111 has an introduction passage 116 to introduce EGR gas. The EGR gas introduced through the introduction passage 116 is guided to cyclone blades 112, while turning along a side wall in the outside cylinder body 110 (see an arrow J). The cyclone blades 112 are provided at predetermined intervals in the circumferential direction. The EGR gas having collided with the cyclone blades 112 forms a spiral swirling flow flowing to the downstream (see an arrow L). As a result, a foreign matter such as a condensate can be appropriately centrifuged. The EGR gas having passed through confluent windows 126 of a reduced diameter part 122, while turning, merges with fresh air, and is supplied to a downstream compressor through an outlet passage 127. |
