Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] Such as figure 1 Shown is a schematic structural view of an embodiment of a screw-type full-barrel feed processing system provided by the present invention. In this embodiment, the screw-type full-barrel feeding treatment system is used to process low- and medium-level nuclear waste and then feed the furnace, which includes: a feeding channel 1, a propeller 2, a waste barrel 3, and a crushing mechanism 4 , screw conveyor 5, waste liquid receiving container ...

Abstract

The invention discloses a spiral type whole bucket feeding treatment system which is used for feeding materials into a smelting furnace after wastes are treated. The spiral type whole bucket feeding treatment system is characterized by comprising a feeding channel (1), a propeller (2), a waste bucket (3), a crushing mechanism (4), a spiral conveyor (5), a waste liquid receiving container (6) and a control system (9). With the adoption of the spiral type whole bucket feeding treatment system, the whole bucket feeding, crushing and addition of additives of a plasma smelting furnace can be effectively realized; the continuous, uniform, stable and reliable feeding is guaranteed; the feeding treatment of a plurality of different formulas can be met, and the influences on operators by a radiation dosage can be reduced.

Description

technical field [0001] The invention relates to the technical field of waste treatment in nuclear power plants, in particular to a screw-type full barrel feeding treatment system. Background technique [0002] A certain amount of radioactive waste will inevitably be generated during the operation and maintenance of nuclear power plants, and these radioactive wastes must be treated, for example, by radionuclide stabilization and containment before they can be finally disposed of. At present, for solid radioactive waste, the common treatment process of domestic nuclear power plants is cement solidification technology, but its capacity is too large, which brings great pressure to the disposal of radioactive waste. [0003] In addition, a plasma technology has emerged in the prior art to treat radioactive waste. This plasma technology uses the characteristics of high temperature and energy density of thermal plasma to quickly pyrolyze waste at high temperature. The product is a...
