A kind of additive injection device, including: blind flange, flange, horizontal steel tube, elbow, vertical steel pipe and steel plate, it is characterized in that: vertically steel pipe one end connects through blind flange with elbow one end, the elbow other end connects with horizontal steel tube one end, the horizontal steel tube other end connects with flange, connect at the outer wall of steel pipe through the blind flange vertical steel pipe other end and have steel plate, preferred weld.
The described vertical steel pipe other end is provided with outlet, and exporting as angular cut, otch and horizontal line is 40～80 ° of angles, preferably 50～70 ° angles.
Described angular cut inclined-plane is in the face of the flow direction of logistics.
Described angular cut low side is axially arranged with bar-shaped trough along tube wall, bar-shaped trough a length of 20～30mm, preferably 22～26mm, and width is the 1/3～1/5 of vertical diameter of steel tube.
Described a kind of additive injection device, it is characterised in that: Plate Welding is on the vertical outer wall of steel pipe in the direction back to stream flow, directly in the direction of stream flow.
Described steel plate, width and vertical steel pipe similar diameters, thickness is close with vertical steel pipeline wall thickness.
Described a kind of additive injection device, it is characterised in that: steel plate one end is welded to connect with blind flange, and the other end is welded on vertical steel pipe outer tube wall.
Compared with prior art: this utility model one additive injection device has the advantage that
1) increase the rigidity of ascending pipe, solve branched pipe yielding problem under the intrinsic pressure effect of medium；
2) solve branched pipe to be deformed and vibration problem in supervisor；
3) the yielding problem in ascending pipe cross section local is solved.
3) simple in construction, conveniently install, safeguard, change.
4) practical, simple in construction, be easily achieved, applied widely, equipment investment is few.
The utility model is described in more detail below in conjunction with the accompanying drawings.But the drawings and specific embodiments are not limiting as scope of the present utility model.
