AI Technical Summary

Technical Problem

Existing plasma high-temperature melting technology has problems such as high NOx levels, high corrosivity, high nuclide concentration, and uneven molten pool when treating radioactive waste, which affect the safety, reliability, and long-term stable operation of the equipment.

Method used

The radioactive waste treatment device using a V-shaped plasma torch forms a V-shaped high-temperature plasma arc by setting up a plasma torch cathode and anode in a V-shape inside the furnace. Combined with water vapor as the plasma carrier, the current, voltage and gas volume are adjusted to promote the uniformity and stability of the molten pool. The inner wall of the furnace is made of high-temperature resistant materials.

Benefits of technology

It effectively reduces NOx emissions, improves the uniformity and stability of the molten pool, ensures long-term continuous and stable operation of the equipment, forms qualified glass, and achieves emission standards.
