Rectangular section cross type shunting rectification cross joint

The invention discloses a cross type shunting rectification cross joint, which comprises an inlet section, a first outlet section, a second outlet section and a third outlet section, wherein the first outlet section is positioned on one side of the inlet section and on the same horizontal plane as the inlet section; the second outlet section and the third outlet section are symmetrically positioned on upper side and lower side of the inlet section, and the plane on which the connection of extension lines of the second outlet section and the third outlet section is and the plane on which the inlet section is are vertical to each other to form a cross type structure; the inlet section is connected with the first outlet section through a horizontal connection end of a four-way shunting section; two longitudinal connection ends of the four-way shunting section are symmetrically connected with a buffer section; the other end of the buffer section is symmetrically provided with a rectification section which is connected with the second outlet section and the third outlet section; and the upper end in the rectification section is provided with rectification vanes, and each rectification vane is provided with guide vanes which divide the interior of the rectification section into five equal-flow fluid passages. The unique design of the cross type shunting rectification cross joint eliminates velocity stratification formed after fluid passing through the cross type cross joint, thereby finally fulfilling the aim of rectifying the fluid passing through the cross type cross joint.
