摘要

为了研究金属氢化物反应器的温度变化趋势与规律

搭建了反应器性能测试装置

通过实验获得了吸氢反应过程中氢化物床层和换热流体的温度变化数据。实验结果表明:床层最高温度和换热流体出口温度都随着供氢压力的增大而升高。当供氢压力从0.6 MPa提高到1.0 MPa时

床层最高温度从56.6 ℃提高到71.8 ℃。考虑到经济性与安全性等问题

对于镧基金属氢化物反应器其供氢压力最好限定在1.6 MPa以下。换热流体流量越大则床层温度下降得越快

但其强化效果有限。流体出口温度升高幅度则随着流量增大而显著降低

但床层最高温度几乎无变化。氢气注入流量越大

反应器内氢气压力升高得越快

相应地氢化反应越快。通过改变氢气流量可以控制放热反应过程

从而更好地适应用热需求。

Abstract

In order to study the temperature variation of metal hydride heat pump reactor

an experimental setup for performance test of the heat pump reactor was built. The temperature variation of the hydride bed and heat transfer fluid in hydrogen adsorption reaction was measured. The experimental results show that both the maximum temperature of the hydride bed and outlet temperature of heat transfer fluid rise with the increase of the hydrogen supply pressure. When the hydrogen supply pressure increases from 0.6 MPa to 1.0 MPa

the maximum temperature of the bed rises from 56.6 to 71.8 ℃. Considering cost and safety

hydrogen supply pressure should be lower than 1.6 MPa for La-based metal hydride reactor. The higher the flow rate of heat transfer fluid is

the faster the bed temperature drops

but this heat transfer enhancement effect is very limited. When the fluid flow rate increases

the temperature rising magnitude of the fluid reduces remarkably

while the maximum temperature of the bed basically keeps unchanged. It can also be found that the higher the hydrogen injection flow rate is

the faster the hydrogen pressure in the reactor rises

resulting in faster hydrogenation reaction. The exothermic reaction process can be controlled by changing the hydrogen flow rate

thus more favorably meeting the demand for heat application.
