AI Technical Summary

Technical Problem

In existing liquid lithium-lead cladding systems used in fusion reactors, the induced current generated during the liquid lithium-lead flow cannot be effectively utilized, leading to increased energy loss and higher operating costs.

Method used

Design a liquid lithium-lead cladding system that includes a magnetohydrodynamic (MHD) power generation system. By forming a closed loop through the induced current generated during the flow of liquid lithium-lead, and transmitting it to an external electrical load, the efficient utilization of electrical energy is achieved using MHD power generation technology.

Benefits of technology

The energy loss of the liquid lithium-lead cladding was reduced, the energy conversion efficiency was improved, and the closed current loop was reduced by regulating the flow direction of the induced current, thereby increasing the power generation of magnetohydrodynamic power.

Abstract

本发明公开一种包含磁流体发电系统的液态锂铅包层,包括第一壁、阳极板、液态锂铅流道、外部电路、用电负载、阴极板、径向隔板、环向隔板、侧壁,液态锂铅作为氚增殖剂与冷却剂在增殖区中流动,增殖区的边界由侧壁、阳极板及阴极板组成,其内部被起支撑作用的径向及环向隔板分隔出多个并联的管道,并联管道极向贯通,液态锂铅在其中沿极向流动。包层位于强磁场工况下,导电液态锂铅在沿极向流动过程中会产生感应电流,在绝缘径向隔板及绝缘侧壁的限制下,感应电流沿径向流动穿过两层导电的环向隔板后,到达阳极板,进入外部负载电路实现电能的利用,最终通过阴极板进入锂铅流道形成闭合电流回路。本发明降低了包层能量损耗,提高能量转换效率。
