Rotary calcining furnace

Abstract

The invention provides a rotary calcining furnace. The rotary calcining furnace comprises a furnace tube, a heating part and a liquid feeding liquid mixing device, wherein the liquid feeding liquid mixing device comprises a liquid mixing container, a turbulence plateand a fixing piece; and the liquid mixing container is provided with a feeding portand a material supplying port,the turbulence plateis fixed inside the liquid mixing container through the fixing part. The rotary calcining furnace is perfect in design, good in performance and convenient to operate, and can well solve the problemsthat materials are not uniform, the inner wall of the furnace tube is bonded, blocked and the like in a radioactive waste liquid rotary calcining process, industrial production is easy to realize, andtechnical support is provided for development and improvement of the two-step cold crucible glass curing technology in China.

Description

technical field

[0001] The invention belongs to the field of radioactive waste liquid treatment, in particular to a rotary calciner. 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 temperature of the molten material in the crucible can be as high a...
