Embodiment

[0021] Such as Figure 1-2 As shown, the main body design of the pump includes: particle inflow inlet 1, particle outflow outlet 2, cover surface 3, particle outflow outlet pipe 4, helium gas vent 5, rotating motor 6, speed regulation chamber 7, particle flow regulation chamber Inlet 8, particle outflow port 9, reverse ventilation port 10 in the regulating chamber. The particles enter the pump body from the particle inflow port 1, and are accelerated by the spiral blades in the pump body. The high-speed particles leave the pump body from the particle outflow port 2. The chamber 7 is designed with four reverse ventilation ports 10, through which the helium gas is introduced so that the particle flow is properly decelerated, thereby increasing the filling rate of the particles.

[0022] Such as image 3 As shown, the three-dimensional helical blade design of the pump: hub end surface 11, rim surface 12, impeller suction surface 13, pore opening surface 14, impeller pressure su...

Abstract

The invention discloses an acceleration pump for transporting thermonuclear fusion solid-state pebble bed particles, comprising: a main body of the pump, an end face, a speed adjustment chamber, a hole design of a helical blade, and a helium pipeline design of the pump body. Wherein, the main body of the pump includes: a particle flow inlet, a particle flow outlet, a cover surface, a rotating motor, a helium gas inlet, and a helical blade; Entering the pump from the designed ventilation holes, the high-speed flow of helium blows the particle balls into the hub surface, and the particles will obtain a larger acceleration radius, which can be accelerated better and prevent particle clogging. The reverse ventilation design of the speed regulating chamber can decelerate the particles, the speed of the particles leaving the speed regulating chamber decreases and the flow rate remains unchanged, and the filling factor of the particles flowing out of the regulating chamber will increase.

Description

technical field [0001] The invention relates to the technical field of thermonuclear fusion reactor cladding, in particular to an acceleration pump for transporting thermonuclear fusion solid pebble bed particles. Background technique [0002] The existing CFETR cladding scheme uses a solid pebble bed for tritium multiplication and neutron multiplication. Since the contact between particles in the particle system is in a metastable state, various forms of disturbance from the outside can easily cause particles to move and change The overall state of the particulate material, which in turn changes other properties of the system. The latest paper pointed out that under certain conditions, the heat-carrying ability of granular materials is no less than that of water and living cells. The engineering design scheme of CFETR mainly adopts two cladding schemes of water cooling and helium. The cooling of the cladding particle flow of the future fusion reactor The program will likel...
