Embodiment Construction

[0037] In order to more clearly express the purpose, technical solutions and advantages of the patent of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] Such as figure 1As shown, the parts to be cleaned are transported by the remote operation device to the hot chamber cleaning unit, and the transport device transports the parts to be cleaned to the bottom of the injector, and the injector sprays high-speed dry ice particles to remove the adhesion and weak solid contamination on the surface of the parts to be cleaned. After completing a cleaning task, spray and purge the interior of the cleaning unit. After cleaning, the dusty exhaust gas is filtered through the pre-dust filter to prevent the solid radioactive particle...

Abstract

The invention relates to a cleaning waste gas pressure swing adsorption purification and recycling method and device for a fusion reactor hot room. The method includes the technological process of cleaning and contaminating, solid and liquid impurity filtration and purification, cleaning medium adsorption separation and regeneration, low-temperature power gas preparation, volatilizable particle regeneration and volatilizable particle remote-distance pneumatic transport. Fusion reactor hot room cleaning waste gas containing radioactive particles and radioactive gas is processed in a low-risk mode through a multiple filtration and pressure swing adsorption method, and separation, classified collection and recycling of radioactive particles, radioactive gas tritium and a cleaning medium carbon dioxide gas are achieved. The purity of regenerated products is high, no external heat source heating is needed, the gas temperature change range is small, the device is more economical and saves more energy, the service life of adsorbent is long, the device maintenance is easy and convenient, automatic production can be completely achieved, and the method and the device are suitable for the hot room environment remotely controlled and operated.

Description

technical field [0001] The invention relates to a method and equipment for cleaning waste gas pressure swing adsorption, purification, regeneration and utilization in the thermal chamber of a fusion reactor, which is suitable for the treatment of the waste gas generated during the activation of the fusion reactor facing the plasma and the maintenance, cleaning and decontamination of the thermal chamber of the tritium retention components. Technology belongs to the field of radioactive pollution control and treatment. Background technique [0002] The gradual depletion of fossil energy is a well-known fact, and renewable energy such as wind energy and solar energy cannot fully meet human needs for energy at present. The discovery, utilization and development of nuclear energy have gone through more than half a century, but there is still a certain degree of uncertainty in the safe utilization of fission nuclear energy by human beings. With the progress of the ITER project, f...
