Abstract

The invention provides a discharging device for a high-temperature glass curing smelting furnace. The device is mainly composed of a metal discharging tray, a ceramic insulation pad and a metal discharging pipe. The metal discharging pipe is arranged in the metal discharging tray, the metal discharging pipe and the metal discharging tray are isolated by the ceramic insulation pad, the dischargingdevice is connected with a furnace bottom discharging port, and after the metal discharging tray and the metal discharging pipe are powered on to form a loop, the discharging port and glass in the metal discharging pipe are gradually heated, and discharging is achieved. In addition, a cooling medium can be injected into the sleeve in the metal discharging pipe, and rapid stopping of the discharging process is achieved. The discharging scheme is simple in operation, controllable in process and capable of guaranteeing efficient and stable operation of the dangerous or radioactive waste glass curing smelting furnace.

Description

technical field [0001] The invention relates to a furnace unloading device, in particular to a unloading device for a high-temperature glass solidification furnace, which can realize the controllable unloading of dangerous and radioactive waste solidified in a high-temperature glass furnace. The invention belongs to the hazardous and radioactive waste treatment technology field. Background technique [0002] Vitrification technology, also known as high-temperature melting technology, refers to the technology of mixing glass additives with hazardous or radioactive waste, melting at high temperature (generally greater than 1100°C) and casting into a glass solidification body. The organic poisons in hazardous or radioactive waste are decomposed into small molecules by high temperature, while the inorganic poisonous elements enter the glass network structure during the high-temperature glass melting process, and solidify them at the atomic scale, thereby preventing the poisonous...
