摘要： One of the challenges in the flotation is the top size of the particles.Application of three phase fluidized bed technology,introduction of air bubbles rising water flow,and comparison with and without air bubbles on the influence of coal particle bed expansion degree were used to conclude that the introduction of bubble flow can strengthen the fluidization of low density particles.And,under three kinds of flow conditions including rising flow in rising water flow only,rising bubble flow and water flow,and bubble flow+collector (kerosene),a coal separation experiment was carried out.Results show that the introduction of bubble flow can significantly reduce the rising flow required for the level of low density particles suspended velocity,the bubble flow's influence on the level of low density particles is better than that on high density coal particles,the existence of the bubble strengthens the coal density,and weakens the effect of particle size on separation.Adding collection agent in the rising bubble flow,the low density particles and bubble form a particle-bubbles combination,low density particles can be separated in a low rise water speed,in a low speed upward water,its steady flow degree is low which can guarantee the stability of the large particles and bubbles.With the addition of the collection agent,the speed of the water flow will be closer for each grain grade particle separation,and the ash of each grain grade will be about 10％.%拓宽浮选粒度上限是浮选领域挑战的难题之一.应用三相流化床技术,在上升水流中引入气泡流,对比有无气泡对煤炭颗粒床层膨胀度的影响,得出气泡流的引入能够加强低密度颗粒的流化.并在单独上升水流、上升水流+气泡流和上升水流+气泡流+捕收剂(煤油)3种水流条件下,进行煤炭分选实验.结果表明,气泡流的引入,能够大幅减少低密度级颗粒悬浮所需的上升水流速度,气泡流对低密度级颗粒的影响强于高密度级,气泡的存在强化了颗粒密度、弱化了粒度对分选的影响;在上升气泡流中添加捕收剂后,低密度级颗粒与气泡形成颗粒-气泡结合体,低密度级颗粒便能够在较低的上升水流速度下进行分选,低速上升水流稳流度较低,保证了大颗粒与气泡的稳定性.添加捕收剂后,各粒级颗粒分选所需上升水流速度较为接近,各粒级精煤灰分在10％左右.

摘要： 常温常压条件下基于欧拉模型，利用Fluent软件对高1．6 m、内径0．09 m的高硫高砷金精矿三相流化床流动特征进行了数值模拟。模拟过程以空气为气相且为连续相，液态水为液相，密度为3．2 g／cm3、粒径为0．5 mm的高硫高砷金精颗粒为固相。模拟结果显示，流场的压力从计算域的入口到出口逐渐降低，速度场的变化对气液固局部相含率的分布影响显著；在径向上，气含率（εg）从计算域中心往边壁降低，在轴向上也逐渐降低；固含率（εs）从计算域的入口到出口逐渐减小，从计算域中心向边壁εs 增加。模拟结果与实验结果一致，可为合理设置气流速度以及金矿投放量提供依据。%The numerical simulation was conducted using the Fluent software based on the Euler model for the flow characteristics of three⁃phase fluidized bed (1.6 m in height and 0.09 m in internal diameter) of a high⁃sulfur and high⁃arsenic gold concentrate under normal conditions. In the simulation, air was taken as continuous gas phase, water as liquid phase and the high⁃sulfur and high⁃arsenic gold concentrate with particle size of 0.5 mm and density of 3.2 g/cm3 as solid phase. Results showed that pressure of the flow field reduced gradually from the entrance to the exit of the computational domain. The variation in the velocity field significantly affected the distribution of local phase holdups. The gas holdup (εg ) decreased from the center to the edge of the computational domain in the radial direction and gradually decreased in the axial direction too. While the solid holdup (εs ) increased from the center to the edge of the computational domain, but gradually decreased from the entrance to the exit. The simulation results were consistent with the experimental results, which will be helpful for setting reasonable air velocity and appropriate dosage of gold.

The minimum fluidization velocity of the three phase fluidized bed is determined as 17. 4 mm/s and finally is verified by high synchronous image acquisition.

摘要： 通过对磷石膏分解渣在三相流化床中碳酸化反应的实验研究,探讨了不同因素对磷石膏分解渣中CaS转化的影响.实验结果表明:增大CO2气体流量和增加反应时间有利于CaS的转化,随着液固比的增大,CaS的转化率首先是增大然后趋于平缓,而升高反应温度对CaS的转化有微弱抑制作用.得到磷石膏分解渣碳酸化反应的最佳反应条件:CO2气体流量为300 mL/min、反应时间为40 min、液固比(体积质量比)为6mL/g、反应温度为(25±2)°C.在最佳反应条件下,三相流化床中CaS的转化率为97.34％,釜式反应器中CaS的转化率为86.32％,相差了11％.与釜式反应器相比,三相流化床反应器更有利于磷石膏分解渣的碳酸化反应.%The carbonation reaction of phosphogypsum decomposition slag in the three-phase fluidized bed was studied, and the influence of different factors on the transformation of CaS in the phosphogypsum decomposition slag was discussed. The results show that the increase of CO2 gas flow and the increase of reaction time are good for the transformation of CaS. The conversion rate of CaS increases firstly and then tends to flatten with the increase of the liquid-solid ratio. The rise of reaction temperature has a weak inhibitory effect on the transformation of CaS. The optimum process conditions of carbonation reaction are as follows: the C02 gas flow is 300 mL/min, the reaction time is40 min, the liquid-solid ratio (volume-mass ratio) is 6 mL/g, and the reaction temperature is (25 ±2) °C. Under the optimum process conditions, the conversion rate of CaS in the three-phase fluidized bed reactor is 97.34% and that in the tank reactor is 86. 32% , with an 11% difference. Compared with the tank reactor, the three-phase fluidized bed reactor is more advantageous for the carbonation reaction of phosphogypsum decomposition slag.

摘要： It is necessary to conduct cold simulation of pretreatment of refractory gold concentrate (RGC) in there-phase fluidized bed, providing key parameters of subsequent hot experiments. Air, water and HGC were used as gas phase, liquid phase and solid phase, respectively. Through theoretical analysis and experimental study, hydrodynamics in three-phase circulated fluidized were studied. The effects of operation conditions on the flow Characteristics were conducted. (1) average gas holdup increased with gas velocity exponentially; liquid circulation velocity increased with gas velocity, and gas-liquid mass transfer mainly occurred in the upper tube; average gas holdup increased with amount of solid particles. (2) At the initial stage, with the increase in gas flow rate, pressure drop between two points dropped. The pressure drop of upper part is the largest, the lower part is the second, the central is minimum. With a further increase in gas flow rate, pressure drop slightly decrease. (3) Under the experimental condition, the correlation of average gas holdup in circulating fluidized bed isεR =0. 12UR0.99.%开展流化床中预处理难浸金精矿之前,需要进行冷模研究,为热态实验提供关键参数.以空气-水-高硫高砷金精矿为物系,采用实验研究和理论分析的方法,开展流化床中难浸金精矿最小流化速度、气含率、固含率、轴向压降等随操作条件的变化研究.研究发现:①平均气含率随气速的增大呈指数增加.②在初始阶段,随着气体流速的增加,两点间压降下降.上部压降最大,下部次之,中部最小.随着气体流速进一步增加,压降下降幅度略微降低.③在实验范围内,三相流化床内的平均气含率与气速的模型关联结果为εg=0.12Ug0.99.

摘要： 采用双通量模型模拟了管式三相流化床光催化反应器中辐射能分布和局部体积能量吸收速率,并采用负载型TiO2/SiO2光催化剂进行了实验验证,考察了液相介质、通气量及催化剂浓度对光辐射强度和体积能量吸收速率的影响.实验结果表明,实验数据和模型计算值能够较好吻合,蒸馏水做液相介质时,可将气液鼓泡流看成单一的连续相,催化剂浓度越大,光辐射能沿径向衰减越大,起始局部体积能量吸收速率越大同时衰减越快.本实验中使用TiO2/SiO2光催化剂时反应器中最佳催化剂浓度为10～12 g/L,此浓度下光辐射能利用率超过85%.完善后的双通量模型对于气、液、固三相光催化反应器的光学厚度设计和催化剂浓度选择具有指导意义.%Two-flux model was applied for the modeling and verification of radiation energy and local volumetric rate of energy absorption (LVREA) in a photoreactor of annular three-phase fiuidized bed with TiO2/SiO2 photocatalyst. The influence of liquid medium, air flux and catalyst concentration on the light intensity and LVREA was investigated. The experimental results indicated that the experimental data could well agree with the calculated data. With the liquid medium of water the liquid and gas could be regarded as a single continuous phase. As the catalyst concentration increased, the radiation energy decayed fast along radial direction while the initial LVREA increased but LVREA along radial direction decayed fast. The optimum concentration of TiO2/SiO2 phtocatalyst was 10 - 12 g/L on which condition the availability of radiation energy was more than 85％. The modified two-flux model has significant effects on the selection of optical depth and catalyst concentration in liquid-solid-gas photoreactors.
