Abstract

A discharging device comprises a discharging component which comprises a material inlet, a channel part and a material outlet, and the discharging component is used for enabling materials to be discharged to flow in from the material inlet, flow along the channel part and flow out from the material outlet; a first heating component arranged on the channel part and used for heating the discharging component; a cooling component arranged on the channel part and used for cooling the discharging component; and a second heating component arranged at the material inlet and used for heating the material inlet. According to the discharging device, the material inlet is further heated, so that the heating rate of the material inlet is increased, the starting of discharging of materials is accelerated, and the discharging efficiency is improved.

Description

technical field [0001] The embodiment of the present application relates to the field of furnace unloading device and process technology, and specifically relates to a unloading device, a cold crucible melting device and a unloading method. Background technique [0002] The radioactive liquid waste produced by the reprocessing of spent fuel has the characteristics of high specific activity, high heat release rate, long half-life of nuclides, and complex chemical composition. How to safely and effectively treat radioactive liquid waste is an important factor affecting the sustainable development of the nuclear industry. one. In recent years, the vitrification process has been used to treat radioactive liquid waste. The vitrification process first pretreats the radioactive waste liquid by calcination to convert it into an oxide (called a calcined product), and then mixes it with the glass substrate in a furnace according to a certain ratio, melts, pours it, and anneals it. F...
