Abstract
In view of a new method that the cavitation releases energy to make full use of the energy,a new type of vortex cavitation was designed.The quantitative analysis of (· OH) production and the relationship between the cavitation intensity by cavitation was proceeded.The methylene blue as capture agent of hydroxyl radical,the ultraviolet-visible spectrophotometer was used to indirect determination of (· OH) production generated by the hydraulic cavitation,and the experimental study of the vortex cavitation effect was carried on by the method.The influences of the vortex cavity diameter,cavitation produced liquid pipe diameter and cavitation in liquid flow rate etc.process parameters on the free radical production were analyzed.The appropriate design of cavitation process was looked for which benefit for cavitation occurring and cavitation effect adapting.The results show that the liquid pipe flow rate is more rapid,the produced liquid pipe diameter is smaller,and the vortex cavity diameter is smaller,and the concentration of (· OH) is greater.Compared with the orifice hydraulic cavitation device,the · OH molarity of vortex cavitation device is 13.99 ～ 68.19 times of the orifice hydraulic cavitation.It indicates that the vortex cavitation has higher energy utilization efficiency and better cavitation effect.关键词
