A novel uniform-flow liquid lithium restrictor structure for use in fusion devices

Abstract

The invention discloses a novel uniformly flowing liquid lithium limiter structure applied to a fusion device, which comprises a collection box, wherein the bottom end of the collection box is provided with double built-in electromagnetic pump, a limiter base is arranged above the collection box, the base of the limiter base is provided with a heating wire and a thermocouple, the outer surface ofthe inner side of the limiter base is clamped with supply pipes connected with liquid lithium, a pump channel is welded between two electrodes in the double built-in electromagnetic pump, the pump channel is communicated with the supply pipes above, the top of the limiter base is provided with a distribution box, and the distribution box is integrally molded and has a structure with uniformly distributed distribution holes. The novel uniformly flowing liquid lithium limiter structure can better achieve supply of the liquid lithium by using a device toroidal field and the additional direct current driving double built-in electromagnetic pump structure, can realize uniform distribution of the liquid lithium through the integrally molded distribution box, and can effectively improve the spreading uniformity of the liquid lithium by using the limiter base with good lamination and a micro-capillary structure perpendicular to the flowing direction of the liquid lithium.

Description

Technical field: [0001] The invention relates to the field of fusion reactors, and mainly relates to a novel uniform flow liquid lithium limiter structure used in fusion devices. Background technique: [0002] Magnetic confinement controlled nuclear fusion is one of the important ways to solve human energy and environmental problems. With the continuous upgrade of the fusion device, the interaction between the plasma and the wall material facing the plasma (the first wall) gradually becomes stronger, which causes the damage and corrosion of the wall material to intensify, which seriously affects the operation safety of the fusion device. One-wall material is one of the "bottlenecks" restricting the development of controlled fusion. [0003] On the one hand, tungsten, as the first wall material in the high heat load area of ​​the future ITER device, can withstand 5-10MW / m 2 However, in the future fusion reactor device, tungsten will be severely corroded under long-term high...
