Embodiment 1

[0050] A microwave heating treatment device for high-radioactive nuclear industrial waste, its structure is as follows figure 1 and figure 2 As shown, it includes a sealed box 1, the top of the sealed box 1 is provided with a microwave heating hole 2 and an exhaust hole for discharging water vapor, a lifting device 9 is arranged below the microwave heating hole 2, and a sealing The door 10, the inside of the sealed box 1 is provided with a transfer device I8 for sending the barrel containing the high-level waste liquid to or from the lifting device 9, and the outside of the sealed box 1 is provided with a transfer device II11, a transfer device I8 and a transfer device The heights of the devices II11 match each other and are located on both sides of the airtight door 10 respectively.

[0051] When it is necessary to heat, evaporate and reduce the volume of the barreled high-level waste liquid, the barrel 6 containing the high-level waste liquid is transported to the sealing ...

Embodiment 2

[0053] On the basis of Embodiment 1, the conveying device I8 and the conveying device II11 are roller conveyors.

[0054] The transfer device I8 is provided with a tray 12 for carrying the bucket 6 containing the high-level waste liquid to move between the transfer device I8 and the transfer device II11.

[0055] Tray 12 structure such as image 3 As shown, it includes a tray main body 1201. On both sides of the tray main body 1201, there are at least a pair of rotating assemblies 1202 that can roll relative to the side walls of the conveyor I8 and conveyor II11. The upper surface of the tray body 1201 is provided with a placement part for placing buckets .

[0056] The tray main body 1201 is a rectangular plate made of stainless steel, which has a strong load-carrying capacity and can carry heavy barrels 6 containing high-level waste liquid. The four corners of the tray main body 1201 are provided with arc-shaped notches, each Rotating components 1202 are installed at each ...

Embodiment 3

[0059] On the basis of Embodiment 1, the structure of the airtight door 10 is as follows: Figure 5 and Figure 6 As shown, it includes a large door panel 1006 and a small door panel 1002. The edge of the large door panel 1006 is provided with a plurality of screw holes, and the screw holes are used to fix the large door panel on the door frame 10010. The door frame 10010 is fixedly installed on the box body 1 that needs to be sealed. A sealing strip is arranged between the sealing box body 1 to enhance the sealing performance. The side portions on both sides of the door plate 1006 are respectively provided with a linear sliding mechanism I 1005 parallel to the length direction of the door plate 1006, and the chute of the linear sliding mechanism I 1005 is fixed on the door plate 1006 by screws.

Abstract

The invention belongs to the technical field of high-radioactive nuclear industry waste microwave heating treatment and particularly relates to high-radioactive nuclear industry waste microwave heating treatment equipment with an aim to solve problems that in a microwave heating device, high-radioactive liquid waste usually contains more solid waste resulting in proneness to pipe clogging, influence of process efficiency and increasing of radiation risks in the prior art. The technical scheme includes that the high-radioactive nuclear industry waste microwave heating treatment equipment comprises a sealed box, a microwave heating hole is arranged in the top of the sealed box, a lifting device is arranged under the microwave heating hole, a sealing door is arranged on the sealed box, a first conveying device used for conveying a barrel containing high-radioactive liquid waste to the lifting device or away form the same is arranged n the sealed box, a second conveying device is arrangedon the outside of the sealed box, and the first conveying device and the second conveying device are matched in height and are respectively located on two sides of the sealing door. The high-radioactive nuclear industry waste microwave heating treatment equipment is applied to microwave evaporation of the high-radioactive liquid waste.

Description

technical field [0001] The invention belongs to the technical field of high radioactive nuclear industrial waste treatment, and in particular relates to a microwave heating treatment device for high radioactive nuclear industrial waste. Background technique [0002] Radioactive waste immobilization is to transform gaseous, liquid or solid waste into a monolithic solidified body whose performance indicators meet the disposal requirements. Its purpose is to form an object that is suitable for handling, transportation and temporary storage, and whose performance meets the disposal requirements. For high-level waste liquid, the amount of liquid is usually reduced before solidification, so as to facilitate transportation, storage and process development. The existing method for reducing the amount of high-level waste liquid is heating and evaporating, and the method of microwave heating and evaporating is simple in process, low in cost and good in evaporating effect, so it is ve...
