介绍了干扰床分选的原理,对干扰床沉降理论、干扰床流场特性、国内外干扰床设备研究现状等进行了阐述。分析表明,国内干扰床分选理论研究和国外相比,还有差距;适用于干扰床分选设备的沉降理论公式和模型都存在一定局限性,粒子图像测试技术和计算机数值模拟技术为干扰床的研究提供了新的手段;国内外研究者对新型设备的研究,主要集中在对传统干扰床的结构优化、在干扰沉降原理上附加力场和流场、将不同上升水流速的分选室相串联3个方面。
The principle of disturbing bed sorting is introduced. The theory of disturbing bed settling, the characteristics of disturbing bed flow field, the research status of disturbing bed equipment at home and abroad are also described. The analysis shows that there is still a gap between the theoretical research on the theory of domestic disturbance bed separation and that of other countries. There are some limitations on the theory and model of settlement for the interference bed separation equipment. Particle image testing and computer numerical simulation The research on new equipment by researchers at home and abroad mainly focuses on the structural optimization of the traditional disturbance bed, the addition of force field and flow field on the principle of disturbance settlement, and the sorting room with different rising water flow rates In series with three aspects.
