Abstract
An industrial ejector includes: a Laval nozzle in which a first channel which has a throat and along which a fluid flows in a first direction is formed; and a main body which is formed in a tubular shape, in which the Laval nozzle disposed therein is fixed to a part of an inner surface thereof, and in which a second channel is formed between the rest of the inner surface and the Laval nozzle. The second channel is disposed at a first side with respect to the first channel in a second direction perpendicular to the first direction. An opening is obliquely cut and formed in an end of the first channel at a downstream side and inclined toward the first side in the downstream direction and then toward the second channel.

An industrial ejector comprising:
- a Laval nozzle in which a first channel which has a throat and along which a fluid flows in a first direction is formed;
- and
- a main body having a tubular shape and having a second channel, the Laval nozzle being disposed in the main body and fixed to a part of an inner surface of the main body and the second channel being formed between an opposite part of the inner surface of the main body and the Laval nozzle,
- wherein the second channel is disposed at a first side of the channel in a second direction perpendicular to the first direction,
- wherein a cutout that comprises an opening is obliquely cut and formed in an end of the first channel at a downstream side and is inclined toward the first side in the upstream direction and toward the second channel,
- wherein the first channel and the second channel are disposed in parallel, and
- wherein the opening obliquely cut is arranged along an inner surface of the main body.
