The developing status and separating principle of de-oil hydrocyclones are first simply introduced. The ways to enhance the hydrocyclone's separation efficiency are described based on theoretical analysis. One of the ways is to inject air into the hydrocyclones so as to combine them with oil to form oil–gas compound bodies, and then increase the de-oil efficiency. By means of injecting air into the hydrocyclone, a new type of hydrocyclone, i.e. air-injected de-oil hydrocyclone (AIDOH), was developed. The basic separation principle of the AIDOH, prototype structure, the experimental technical process and facilities are introduced. Laboratory experiments were carried out. The effects of different geometric parameters, including the vortex finder diameter, and the length, the micro-pore diameter, and different operating conditions, such as flowrate, split ratio, gas–liquid ratio, and especially the air-injecting position, were studied. It was also found that the best injecting part is at the fine cone segment. Further experimental studies were continued to confirm the detailed part in the fine cone segment, which included one-third segment and two-thirds segment. Results show that the best air-injecting part is the first one-third of the fine cone segment. Research indicates that the AIDOH has satisfied the separation effect. 相似文献

Design and performance evaluation of hydrocyclones for removing micron particles suspended in water 总被引:1,自引:0,他引:1
A hydrocyclone for collecting micron-sized hydrosols efficiently has been studied through experimentation. Hydrocyclones separate
particles of the dispersed phase from the liquid on the basis of the density difference between the phases. The purpose of
this study was to design and evaluate the performance of a high-capacity hydrocyclone for the removal of submicron-sized particles
suspended in liquid. Furthermore, the performance of three types of hydrocyclone was evaluated with regard to solid particle
density using fly ash and coagulation sludge. The particle cut-size decreases with reducing inlet area and increasing inlet
velocity in the hydrocyclone. The hydrocyclones have good performance, which is demonstrated by the optimal cut-size of 20
μm in mass median diameter at the inlet diameter per body diameter ratio of 0.21 and the pressure drop of 72.5 kPa with a
particle density of 2,500 kg/m3. 相似文献

Even though the influence of solids concentration in the feed on the separation efficiency of hydrocyclones has long been recognized, a systematic research on the change in pressure drop across the hydrocyclone and the latter's separation characteristics has thus far been lacking. If all other operating parameters are kept constant, an increase in feed concentration generally leads to a coarser cut size, reduced sharpness of separation and a rise in pressure drop. Apart from the particles hindering one another's radial motion, the limited capacity of the apex valve and the changes in the flow field within the hydrocyclone cause additional particles to be entrained by the overflow. The flow ratio thus becomes an additional parameter in determining the cyclone efficiency. A theoretical model, which takes these effects into account, has been developed and successfully tested against experimental data. 相似文献
