Abstract

The invention provides a bubbling stirring type cold crucible for vitrification and a bubbling stirring method thereof. The bubbling stirring type cold crucible for vitrification comprises a cruciblebottom and bubbling tubes, wherein the number of the bubbling tubes is greater than or equal to 4, all the bubbling tubes penetrate through the crucible bottom of the cold crucible and stretch into the cold crucible, and the distance between an opening of each bubbling tube in the cold crucible and the center line of the cold crucible is different from one another. The bubbling stirring type coldcrucible adopts a special arrangement mode of the openings of the bubbling tubes, the bubbling stirring method of the bubbling stirring type cold crucible adopts impulse type bubbling, which can makea temperature field in a vitrification melt of the cold crucible distributed more uniformly, cannot make obvious stirring dead angles generated, has a good disturbance effect on the inner portion of the melt, achieves a preset stirring effect, requires short time, needs a small number of arranged bubbling tubes, and reduces the influence on the cold crucible vitrification process.

Description

technical field [0001] The invention belongs to the field of radioactive waste liquid treatment, in particular to a bubbling stirring cold crucible for vitrification and a bubbling stirring method. Background technique [0002] Cold crucible vitrification technology is a new generation of vitrification technology currently used in the treatment of radioactive waste in the world. It uses induction coils to convert high-frequency currents into electromagnetic currents, and generates heat through the eddy currents formed in materials by electromagnetic currents to achieve heating and melting. [0003] The cold crucible vitrification device is mainly composed of a high frequency induction power supply, a cold crucible furnace body and other auxiliary systems. The cold crucible furnace body is a circular or oval container composed of a metal arc block or tube through which cooling water passes. When working, cooling water is continuously passed through the metal tube, and the te...
