Experiments were carried out in a lab-scale double-dipleg circulating fluidized bed (DDCFB) to study effects of experiment conditions on re-circulating rate and pressure balance. The results show that the principle of re-circulating rate does not change compared to conventional CFB. There are two pressure balances of circulating loop in the DDCFB. The resistance of de-HCl bed is the key control parameter. By regulating the parameter, it can be realized to make the solids and gas directed and steady flow....

Experiments were carried out in a lab-scale double-dipleg circulating fluidized bed (DDCFB) to study effects of experiment conditions on re-circulating rate and pressure balance. The results show that the principle of re-circulating rate does not change compared to conventional CFB. There are two pressure balances of circulating loop in the DDCFB. The resistance of de-HCl bed is the key control parameter. By regulating the parameter, it can be realized to make the solids and gas directed and steady flow. The formula calculating the resistance of de-HCl bed in the second dipleg is presented by theoretical derivation so that the important design parameter of DDCFB for waste incinerator is offered.

主要研究了试验工况对循环流率的影响以及系统的压力平衡变化。结果表明:在双级料腿循环流化床中,与常规的循环流化床相比,循环流率的规律没有发生变化。系统中存在着两路的压力平衡。对气固两相的稳定、定向流动起关键作用的是通过脱氯床层的阻力。通过理论推导得到了二级料腿内脱氯床阻力的计算公式,为双级料腿循环流化床垃圾焚烧炉提供了重要的设计参数和运行依据。

The incineration technology of double-dipleg circulating fluidized bed, by stage-by-stage conversion and removal of HCl in pre-combustion stage, effectively solves the problem of coupling high temperature corrosion and the emission of dioxins. In this paper, the residence time distribution (RTD) of large particles simulating different components in wastes is investigated in second dipleg of double-dipleg circulating fluidized bed. Experiment results show that circulating flowrate, superficial velocity and density , size of particles all affect the RTD. The mean residence time of particles decreases sharply with an increase of the recirculating rate and slightly decreases as the superficial velocity increases. It appears that the density of particle has a stronger influence on the residence time than the particle size. The lighter the particles are the shorter residence time is. A model consisting of two parallel-mixed flow reactor was presented to simulate the RTD of large particles. The model is supported by the experimental results.

双级料腿循环流化床垃圾焚烧炉采用分级转化技术,燃烧前脱氯,有效解决了高温腐蚀和二噁英造成的二次污染。该文采用不同的大颗粒物料来模拟垃圾中的不同组分,在双料腿循环流化床试验台中研究了颗粒的停留时间分布。结果表明,影响大颗粒停留时间的主要因素是循环流 率、表观流化气速、颗粒的密度和尺寸。循环流率增大,停留时间急剧降低。表观气速对停留时间影响较小。颗粒密度对停留时间的影响比尺寸要大。颗粒越轻,停留时间越短。根据实验结果,建立了两并联全混釜停留时间分布模型,模型计算结果与实验结果吻合较好。

Much research and development has been done on the incineration techniques. However,the technique is far from complete. In this paper, the characteristics of three types of prevailing incinerators in use are summarized. Chlorine in waste is the key matter that will cause corrosion and produce dioxins. A new concept of waste incinerator-double -dipleg circulating fluidised bed is proposed at the institute of process engineering. By staged conversion,the three difficulties of prevent the corrosion and reduction of dioxins and heavy metal can be solved simultaneously.
