Quick gas jet mixer with high homogeneity

The quick gas jet mixer consists of one conic tube with jet hole on the side wall and one straight tube. The conic tube is installed inside the straight tube and the conic tube separates the straight tube into one distributing cavity and one mixing cavity. On the top of the conic tube, there is one distributing board communicated with the first gas inlet; and the distributing cavity is communicated with the second gas inlet. The device of the present invention has simple structure and may be used to complete the mixing of two gas flows in high homogeneity instantaneously.
