Automatic glass slag discharge device for plasma melting furnace

Abstract

The invention discloses an automatic glass slag discharge device for a plasma melting furnace. The automatic glass slag discharge device comprises a discharge channel, a high-temperature fire resistant fiber layer, a first heat preservation layer and a temperature control device; the high-temperature fire resistant fiber layer encloses the discharge channel and is used for keeping the temperaturestability of the discharge channel, and a sealed cavity is formed between the high-temperature fire resistant fiber layer and the discharge channel; the first heat preservation layer wraps the high-temperature fire resistant fiber layer; the temperature control device penetrates through the first heat preservation layer and the high-temperature fire resistant fiber layer in a sealed mode and is placed in the sealed cavity and used for controlling and adjusting the temperature; and the temperature control device controls and adjusts the temperature in the discharge channel to the specified value, so that a glass solidified body in the discharge channel is melted and flows out through a discharge outlet. According to the automatic glass slag discharge device for the plasma melting furnace, the magnitude of the discharge flow of the glass solidified body can be controlled, and the discharge reliability of glass-state slag is strengthened; and the automation level is improved, and radioactive environmental contamination is reduced.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to an automatic glass slag discharge device for a plasma melting furnace. Background technique [0002] In the prior art, the plasma treatment technology can be applied to the disposal of most medium and low radioactive wastes, especially for refractory wastes. For organic waste, the high temperature of thermal plasma can decompose the organic components, and the decomposed small molecule gas is further burned in an oxygen environment; for inorganic waste, the high temperature of thermal plasma can also melt the inorganic components, and after melting, it will pass through the automatic The discharge device discharges the material, and finally forms a solidified body with uniform texture. [0003] The existing automatic glass slag discharge device for plasma melting furnace has the following technical problems due to unreasonable structural design: [0004] 1. The discharge of slag ca...
