However, the increasing emphasis on environ- ment protection and gassolid separation is indicating that finer and finer particles must be removed. To meet this challenge, the improvement of cyclone geometry and per- formance is required rather than having to resort to alterna- tive units. Many researchers have contributed to large volume of work on improving the cyclone performance, by introducing new inlet design and operation variables. These include studies of testing a cyclonic fractionator for researchers, was developed, and the experimental study on addressing the effect of inlet type on cyclone performances was presented. 2. Experimental Three kinds of cyclone separators with various inlet geometries, including conventional tangential single inlet have became one of most important particle removal device that preferably is utilized in both engineering and process clean air by Lim et al. 6. In this paper, the new inlet type, which is different type of inlet from that used by former simplicity to fabricate, low cost to operate, and well adapt- ability to extremely harsh conditions, cyclone separators Keywords: Cyclone; Symmetrical spiral inlet; Collection efficiency; Pressure drop 1.

Experimental result indicated that the symmetrical spiral inlet (SSI), especially CSSI inlet geometry, has effect on significantly increasing collection efficiency with insignificantly increasing pressure drop. In addition, the results of collection efficiency and pressure drop comparison between the experimental data and the theoretical model were also involved.

The effects of inlet type on cyclone drop, were investigated and compared as a function of cation spiral inlet to improve 4750 (CTSI), direct symmetrical spiral inlet (DSSI), and converg- ing symmetrical spiral inlet (CSSI), were manufactured and studied. The geometries and dimensions these cyclones are presented in Fig. 1 and Table 1. To examine the effects of inlet type, all other dimensions were designed to remain the same but only the inlet geometry. The pressure drops were measured between two pressure taps on the cyclone inlet and outlet tube by use of a digital by 0.151.15% and 0.402.40% in the tested velocity range. Fig. 4(a)(d) compares the grade collection efficiency of the cyclones with various inlet types at the flow rate of 3 Fig. 2. Schematic diagram of experimental system setup. B. Zhao et al. / Powder Technology 145 (2004) 475048 micromanometer (SINAP, DP1000-IIIC). The collection efficiency was calculated by the particle size distribution, by use of microparticle size analyzer (SPSI, LKY-2). Due to having the same symmetrical inlet in Model B or C, the flow rate of each inlet of multiple cyclone was equal to another and controlled by valve; two nozzle-type screw feeders were used in same operating conditions to disperse the particles with a concentration of 5.0 g/m 3 in inlet tube. The solid particles used were talcum powder obeyed by log-normal size distribution with skeletal density of 2700 kg/m 3 , mass mean diameter of 5.97 Am, and geometric deviation of 2.08. The mean atmospheric pressure, ambient temperature, and relative humidity during the tests were 99.93 kPa, 293 K, and less than 75%, respectively. 3. Results and discussion The experimental system setup is shown in Fig. 2. Fig. 1. Schematic diagram of cyclones geometries: (a) conventional tangential single inlet, Model A; (b) direct symmetrical spiral inlet, Model B; (c) converging symmetrical spiral inlet, Model C. 3.1. Collection efficiency Fig. 3 shows the measured overall efficiencies of the cyclones as a function of flow rates or inlet velocities. It is usually expected that collection efficiency increase with the entrance velocity. However, the overall efficiency of the cyclone with symmetrical spiral inlet both Models B and C was always higher than the efficiency of the cyclone with conventional single inlet Model A at the same velocity; and especially, the cyclone with CSSI, Model C has a highest overall efficiency. These effects of improved inlet geometry contribute to the increase in overall efficiency of the cyclone Table 1 Dimensions of cyclones studied (unit: mm) DD e hH B Sab 300 150 450 1200 1125 150 150 60 388.34, 519.80, 653.67, and 772.62 m /h, with the inlet velocities of11.99, 16.04,20.18, and23.85m/s,respectively. As expected, the frictional efficiencies of all the cyclones are seen to increase with increase in particle size. The shapes of the grade collection efficiency curves of all models have a so-called S shape. The friction efficiencies of the DSSI (Model B) and CSSI cyclones (Model C) are greater by 210% and 520% than that for the CTSI cyclone (Model A), respectively. This indicates that the inlet type or geometry to the cyclone plays an important role in the collection efficiency. It was expected that particles introduced to the cyclone with symmetrical spiral inlet (Models B and C) would easily be collected on the cyclone wall because they only have to move a short distance, and especially, the CSSI (Model C) changes the particle concentration distribution and makes the particle preseparated from the gas before entering the main body of cyclone. Fig. 5 compares the experimental data at a flow rate of 653.67 m 3 /h (inlet velocity of 20.18 m/s) with existing classical theories 711. Apparently, the efficiency curves based on Mothes and Loffler model and Iozia and Leiths method match the experimental curves much closer than other theories do. This result corresponds with the study carried out by Dirgo and Leith 12 and Xiang et al. 13. Fig. 3. Overall efficiency of the cyclones at different inlet velocities. velocity B.

The comparison show that some model can predict a theoretical result that closed the experimental data, but the changes of flow pattern and particle concentration distribu- tion induced by symmetrical spiral inlet having effects on cyclone performance were not taken into account adequately in developed theories. To examine the effects of the symmetrical spiral inlet on cyclone performance more clearly, Fig. 6 was prepared, depicting the 50% cut size for all models with varying the flow rate or inlet velocity. The 50% cut size of Models C and B are lower than that of Model A at the same inlet Fig. 5. Comparison of experimental grade efficiency with theories. =11.99 m/s. (b) Inlet velocity=16.04 m/s. (c) Inlet velocity=20.18 m/s. velocity. As the inlet velocity is decreased, the 50% cut size is approximately decreased linearly. With inlet velocity 20.18 m/s, for example, the decrease rate of 50% cut size is up to 9.88% for Model B and 24.62% for Model C. This indicated that the new inlet type can help to enhance the cyclone collection efficiency. 3.2. Pressure drop The pressure drop across cyclone is commonly expressed as a number gas inlet velocity heads DH named the pressure Fig. 6. The 50% cut size of the cyclones. inlet velocity are presented in Table 2. Obviously, higher pressure drop is associated with higher Barth 5.18 B. Zhao et al. / Powder Technology 145 (2004) 475050 flow rate for a given cyclone. However, specifying a flow rate or inlet velocity, the difference of pressure drop coef- ficient between Models B, C, and A is less significant, and varied between 5.21 and 5.76, with an average value 5.63, for Model B, 5.225.76, with an average value 5.67, for Model C, and 5.165.70, with an average value 5.55, for Model A, calculated by regression analysis. This is an important point because it is possible to increase the cyclone collection efficiency without increasing the pressure drop significantly. The experimental data of pressure drop were also compared with current theories 1420, and results are presented in Table 3. The results show that the model of Alexander and Barth provided the better fit to the experimental data, although for some cyclones the models of Shepherd and Lapple and Dirgo predicted equally well. 4. Conclusions A new kind of cyclone with symmetrical spiral inlet drop coefficient, which is the division of the pressure drop by inlet kinetic pressure q g m i 2 /2. The pressure drop coeffi- cient values for the three cyclones corresponding to different Table 2 Pressure drop coefficient of the cyclones Cyclone Inlet velocity (m/s) model 11.99 16.04 A 5.16 5.18 B 5.21 5.27 C 5.22 5.35 Table 3 Comparison of pressure drop coefficient with theories Theory Shepherd Alexander First Stairmand Value 6.40 5.62 6.18 5.01 (SSI) including DSSI and CSSI was developed, and the effects of these inlet types on cyclone performance were tested and compared. Experimental results show the overall efficiency the DSSI cyclone and CSSI is greater by 0.15 1.15% and 0.402.40% than that for CTSI cyclone, and the grade efficiency is greater by 210% and 520%. In addition, the pressure drop coefficient is 5.63 for DSSI cyclone, 5.67 for CSSI, and 5.55 for CTSI cyclone. Despite that the multiple inlet increases the complicity and the cost of the cyclone separators, the cyclones with SSI, especially CSSI, can yield a better collection efficiency, obviously with a minor increase in pressure drop. This presents the possi- bility of obtaining a better performance cyclone by means of improving its inlet geometry design. References 1 Y.F. Zhu, K.W.

Table 1:旋风分离器尺寸统计:(单位mm)Fig.2:试验结构系统示意图图所示为实验系统机构。 压降是由接在旋风分离器进口和出口管的两压力计测量的。通过一数字微压计(SINAP ,压差1000-IIIC )读得。收集效率是通过微颗粒大小分析器(SPSI,LKY -2)所得粒度分布计算的。由于Model B,C具有一样对称的进口,所以组合式旋风分离器各进口的流速是相等的。并且流速可由阀来控制;运行条件也相同,将浓度为5.0g/m3的粒子用双喷管螺旋给料机喂到进口管中。固体颗粒为滑石粉核心密度的2700kg/m3,按原标准尺寸分配,平均直径的5.97Am,几何偏差为2.08。在这次测试过程中平均大气压,环境温度,和相对湿度分别是99.93kPa,293K,75%。结果和讨论3.1 收集效率图3显示所测量的旋风分离器总效率与流速或者进口速度的关系。正如预料的那样收集效率随进口速度的增加而增加。然而,Model B Model C两旋风分离器有着对称的蜗管进口,在同一进口速度下,两者的总效率永远要高于传统的单一切向进口旋风分离器(Model A),特别是有CSSI的旋风分离器(Model C)的总效率最高。在测试给定的相同速度条件下,通过改善进口几何形状所带来的旋风分离器总效率的增加率分别为0.151.15%和0.402.40%。图4(a)(d) 比较不同进口类型的旋风分离器的分级收集效率。在进口速度分别为11.99,16.04,20.18,和23.85m/s时的流速分别为388.34,519.80,653.67,和772.62 m3/h。可见,旋风分离器的摩擦效率随粒子大小的增加而增加。所有旋风分离器的分级收集效率曲线都呈S形。DSSI(Model b)和CSSI(Model c)旋风分离器的摩擦效率分别比CTSI旋风分离器(Model a)大210%,520%。这表明进口的几何形状对旋风分离器的收集效率有着重要的影响。进入有对称的蜗管进口的旋风分离器(Model B和C)的粒子容易聚集在旋风分离器壁上,因为粒子只能移动很短的位移,尤其CSSI(Model C)改变了粒子分布浓度并使粒子在进入旋风分离器的筒体前就从气体中分离了出来.图5根据传统的理论711比较了流速为653.67m3/h(进口速度为20.18m/s)时的试验数据。很明显,以Mothes /Loffler模型Iozia/ Leith 理论得出的效率曲线比其它的学说所得的曲线更符合试验结果。这些结果与研究进行经过Dirgo、Leith 和Xiang 等人的研究结果相吻合。Fig.3 不同进口速度下旋风分离器的总效率比较表明有些模型可以推断一个还没有公开的理论结果。但是现有的试验数据理论还不足以推断出流态和粒子浓度分布的变化是对称的蜗管进口对旋风分离器性能产生的效果。为了更清楚地验证对称的蜗管进口对旋风分离器性能的作用效果,再看图6,表示随着流速或进口速度的变化引起的各个模型的50%切截尺寸。在相同进口速度下model c和model b的50%切截尺寸比model a要低。与进口速度的减少一样,50%切截尺寸也是近似呈线性减少的。例如,当进口速度为20.18m/s时,50%切截尺寸的减少率由model b的9.88%和model c的24.62%决定。这表明新型进口可以促进旋风分离器的收集效率。3.2.压降旋风分离器得压差数值通常表示为一定数量的气体入口速度压头高度差,用压差数值系数表示,压差数值系数是进口动压压差数值的分度。表2列出了在不同的入口速度时这三个旋风分离器的压差数值系数值。显然,旋风分离器的压降高低与流速高低有关。然而,一定流速或者入口速度下,A、B和C模式的压力降系数有所不同,在5.21和5.76之间变化,其平均值为5.63。例如模式B在5.225.76之间变化,平均值为5.67;模式C在5.165.70之间变化平均值为5.55;模式A根据回归分析计算。这是一个重点,因为由此有可能在没有有效的压差值增加的情况下提高气旋收集效率。表3列出了压降的试验数据与电流理论的比较结果。结果显示Alexander和Barth模式与试验数据最符合,尽管Shepherd ,Lapple 和Dirgo 气旋模式推算也很出色。Fig.4 不同进口速度时的选粉效率等级:(a)进口速度为11.99 m/s (b)进口速度为16.04 m/s (c) 进口速度为20.18 m/s (d) 进口速度为23.85 m/s.Fig.5 试验所得效率等级与理论的比较 Fig.6 旋风分离器的50%切截尺寸Table 2 :旋风分离器的压力损失系数:Table 3 :与理论压力损失系数比较:4、结论人们发明了一种具有对称的蜗管进口(SSI),DSSI和CSSI的新型旋风分离器,并且测试和比较了这种进口类型的旋风分离器的性能。实验结果显示这种DSSI旋风分离器和CSSI旋风分离器的总效率分别比CTSI旋风分离器高出0.151.15%和0.402.40%。此外,DSSI旋风分离器、CSSI旋风分离器和CTSI旋风分离器的压力损失系数分别是5.63、5.67和5.55。尽管这些并联进口增加了旋风分离器的复杂程度并加大了其成本,然而具有SSI尤其是CSSI的旋风分离器具有更好的收集效率,而且显著的减少了压力损失。这篇文章介绍了借助于改进进气道几何形状设计而改善旋风分离器性能的可能性。 参考资料:1 Y.F.
