  • Patent number: 10464038
    Abstract: A mixer and a reactor including the same are provided. According to one aspect of the present invention, the mixer includes a first piping part into which a first fluid flows, an elbow piping part having an inlet connected to the first piping part and an outlet provided at a location rotated by a predetermined angle from the inlet in a flow direction of the first fluid to have a curved flow path, and a second piping part connected to the elbow piping part to have a central axis perpendicular to a central axis of the first piping part so that a second fluid flows in a tangential direction of the elbow piping part when the second fluid flows into the elbow piping part.

  • Publication number: 20160158681
    Abstract: Disclosed here is a separator. The separator includes a cylindrical body in which a spatial portion is provided for separation, a supply pipe provided so that the mixture is introduced in a tangential direction of the cylindrical body to generate a revolving gas flow of the mixture in the spatial portion, a discharge pipe provided so that the first material is discharged to the outside through a rising gas flow of a central portion of the spatial portion, and a deflector provided to be parallel to the supply pipe in a circumferential direction of the spatial portion to prevent the mixture introduced into the spatial portion through the supply pipe from rising.
