摘要

提出一种R134a制冷剂太阳能光催化降解齿形双层管结构的反应器,以改善槽式聚光反应器光子利用率低和太阳辐照度分布不均的问题。以所提变密度齿和均密度齿反应器为研究对象,对反应器的反应、传热性能进行模拟分析。研究结果表明：在不考虑温度影响时,所提出的齿形反应器可大幅提升总反应速率;当考虑温度影响时,总反应速率提升效果有所减弱,但大齿数的变密度齿仍能在大部分情况下起效。变密度齿表现出比均密度齿更优秀的反应和传热性能。

Abstract

A double-tube gear-shaped reactor for solar photocatalytic degradation of R134a was proposed to address the problems of low photon utilization rate and uneven irradiance distribution in the parabolic-trough concentrating reactor. The reaction and heat-transfer performance of the proposed variable-density and uniform-density gear-shaped reactors was analyzed numerically simulations. The research results show that when the influence of temperature is not considered, the proposed gear-shaped reactor can significantly increase the total reaction rate. When the influence of temperature is taken into account, the reaction-rate enhancement is somewhat reduced, but variable-density gear-shaped reactors with larger numbers of teeth remain effective in most cases. Variable-density gear-shaped reactors exhibit better reaction and heat-transfer performance than uniform-density gear-shaped reactors.
