The invention provides an injection device capable of strengthening mixing, and belongs to the technical field of fluid. The injection device mainly comprises an injection pipe, a fan cover and guide vanes. The injection pipe comprises an injection pipe outer wall, an injection pipe inner wall, inner spiral flow guide fins, injection holes and injection strip seams. The inner spiral flow guide fins are of a hollow thin-wall structure and are fixedly connected with the outer wall of the injection pipe to form injection strip seams. And the injection holes are uniformly distributed on the inner spiral flow guide fins. The fan cover and the outer wall of the injection pipe form an annular channel for injecting gas, the radial distance of the annular channel is the same as the radius of the inner wall of the injection pipe, and the fan cover completely covers the axial length of the injection strip seam. High-temperature gas and low-temperature gas can be fully and efficiently mixed within a short distance, the problem that gas mixing of an existing injection device is insufficient is solved, and the injection device has great advantages under the condition of narrow space.
本发明提出了一种强化混合的引射装置,属于流体技术领域。该引射装置主要包括引射管、风罩和导流叶片。所述引射管包括引射管外壁、引射管内壁、内螺旋导流肋片、引射孔、引射条缝。所述内螺旋导流肋片为中空薄壁结构,与引射管外壁固连,形成引射条缝。所述引射孔均匀分布在内螺旋导流肋片上。所述风罩与引射管外壁形成引射气体的环形通路,环形通路的径向距离与引射管内壁半径相同,所述风罩完全覆盖引射条缝的轴向长度。本发明在较短的距离内可实现高低温气体的充分高效混合,解决了现有引射装置气体混合不充分的问题,在空间局促的情况下具有较大的优势。
