Multi-level and multi-direction Y-type impinging jet mixer

2009 
The invention relates to a multi-level and multi-direction Y-type impinging jet mixer provided with multi-level impinging jet passages; an acute angle is formed between jet flows of each impinging jet passage at the same level, and the jet flows converge in a same impinging zone of the jet flows, mixed flow paths formed after each jet flow is impinged are positioned on a same straight line, and the impinging zone of the jet flows at different levels are alternatively, conterminously or overlappedly arranged on the straight line. Generally, the direction of the mixed flow at each level is vertically downward, the center of the impinging jet zone at the post level is positioned below the center of the impinging jet zone at the front level or is overlapped with the center of the impinging jet zone at the front level, the jet flow passages are two-level or three-level, the number of the jet flow passages at the same level is 2 or 3, and the jet flow passages at the same level are uniformly and symmetrically distributed. The mixer can realize momentary fall mixing of different materials with different flow rates and different temperatures, and the mixing process can be continuously and stably carried out mainly for polymerization process of aramid 1414, and the like.
