气升式浆态床反应器是一种重要的气-液-固多相反应器,包括鼓泡塔反应器和环流反应器。这些反应器具有剪切应力低、混合程度好、传质/传热能力强、成本低等优点,已被广泛应用于许多工业过程,尤其是生物发酵和能源化工领域。为了进一步提高浆态床反应器的性能(即混合和传质/传热性能)和满足工业应用要求(如温度控制、减少返混和产品分离等),浆态床反应器的过程强化至关重要。首先,本文回顾了这两种反应器在强化混合和传质/传热方面的最新研究进展。然后,总结了浆态床反应器在连续生产时混合与分离的过程强化方法,其中,由于具有高效率和低成本的优点,推荐采用将环流反应器内的定向流动与水力旋流器的简单固-液分离相结合的过程强化技术。接着,系统地讨论了浆态床反应器所面临的问题和挑战,包括流型判别、气体分布器设计、固体颗粒影响及其他问题。本文还介绍了应用计算流体力学对浆态床反应器进行数值模拟的研究进展,讨论了建模的难点。最后,对工业浆态床反应器的设计进行总结和展望。

An innovative and efficient design of solar receivers/reactors can enhance the production of clean fuels via concentrated solar energy. This study presents a new jet-type burner nozzle for gaseous feedstock injection into a cavity solar receiver inspired from the combustion technology. The nozzle design was adapted from a combustion burner and successfully implemented into a solar receiver and studied the influence of the nozzle design on the fluid mixing and temperature distribution inside the solar receiver using a 7 kW solar simulator and nitrogen as working fluid. Finally, a thorough computational fluid dynamics (CFD) analysis was performed and validated against the experimental results. The CFD results showed a variation of the gas flow pattern and gas mixing after the burner nozzle adaptation, which resulted an intense effect on the heat transfer inside the solar receiver.

考虑到人口众多,经济快速发展,人民生活水平不断提高,人均能源相对贫乏和环境保护,国家已决策加快核能应用的发展。采用压水堆-快堆匹配闭式燃料循环达到核能供应的快速增长和可持续性的基本战略已经决定,也决定了分离和用快堆和ADS对高放废物(MA)的嬗变战略。笔者建议快堆工程发展将分三步进行,中国实验快堆(CEFR,65 MWt/20 MWe),中国原型/示范快堆(CEFR/CDFR,大于等于1 500 MWt/600 MWe)和中国经济验证性快增殖堆(CDFBR,1 000 MWt/1 500 MWe)。CPFR的设计研究已于2006年开始目前正处于安装、调试阶段,计划2009年首次临界。近期讨论建造比600 MWeCPFR更大功率的堆作为CDFR,以加速快堆商用的步伐。
