【摘要】 利用工业废气废水自身的低位余能及热力学势差,构建内源性推动力"场"与吸收"面"共生的以废治废分离机制,发展一种废气横掠废水液柱流的气液交叉流阵列,为提高纤维绳壁面降膜的均匀性和稳定性,提出一种新型的布膜装置。在实验的基础上探讨了液体在纤维绳外壁降膜的流动特性,分析影响液体管外成膜均匀性和稳定性的影响因素,提出液体成膜的最佳环隙间距应控制在0.8 mm,液体流量应控制在35.2~195.7m L/min。更多还原

【Abstract】 Taking advantage of its own potential difference of low level surplus energy and thermodynamics of the industrial waste air and waste water,building a separation mechanism of treatment of wastes with processes of wastes against one another based on the symbiotic relationship between an endogenous impetus the " field " and absorption the " surface ",developing a kind of gas- liquid cross flow array by exhaust gas sweeping across solid stream of waste water,in order to increase uniformity and stability of the falling film of high- fiber rope,this paper presents a new type of film distributor. On the basis of experiments,this paper discusses the flow characteristics of liquid on the outer wall of the fiber rope falling film,and analyzes the influencing factors of uniformity and stability of film formation outside the liquid tubes,as well as proposes that the optimal annular gap distance for fluid film formation should be controlled at 0. 8 mm and the liquid flow should be controlled at 35. 2 ~ 195. 7mL / min.更多还原
