The present invention relates to oscillation-flow flocculating process and apparatus. The suspension with particle is made to flow through a tubular passage with inner baffle part continuously, and one oscillation speed component produced by one oscillation flow generating mechanism sis superposed onto the average flow speed. Inside the oscillation flow field, are realized the dispersing and mixing of the flocculant in the suspension liquid, adsorption between the flocculant and suspension particle surface, collision and merging between the suspension particles, the formation and growth of flocculant, and other physical and chemical processes. By means of the oscillation flow reinforced transmission process, suspension with large flocculant is obtained in the outlet of the apparatus, and this is favorable to the subsequent liquid/solid separation. |
