Description
Technical Field
The invention relates to the technical field of radioactive solid waste treatment, in particular to a super-press for compacting and reducing volume of nuclear radioactive solid waste and waste resin.
Background
With the development of the nuclear industry, a great amount of radioactive waste is generated by civil defense and is stored together with a steel drum containing the radioactive solid waste after the waste liquid is evaporated into solid waste. However, the storage devices for storing the radioactive wastes have high manufacturing cost and small space, and if the steel drums are directly placed into a special storage room for temporary storage, the space utilization rate is low, effective storage cannot be realized, and additional storage cost is increased. It is therefore necessary to use a super press to compact the steel drum into a cake shape together with the solid waste to improve the utilization of the storage space.
In order to facilitate the uniform compaction of the steel barrel, the diameter of a pressure head equipped in the conventional super press is approximately equal to the diameter of the steel barrel, and the contact area between the pressure head and the steel barrel is large, so that the pressure applied to the steel barrel by the pressure head is small, and the output power of the super press needs to be increased to increase the pressure transmitted to the pressure head, so that the steel barrel can be smoothly and uniformly compacted. After the super-pressure machine reaches a certain volume and output power, the cost and the cost for further improving the output power are extremely high, and the output power of the super-pressure machine cannot be improved infinitely.
The diameter of a pressure head of the overpressure machine is obviously smaller than that of the steel barrel, and the contact area of the pressure head and the steel barrel is smaller. Under the same output power of the super-press, a smaller pressure head can apply higher pressure to the steel barrel, so that the steel barrel is more easily compacted; however, the uniformity of the compaction of such over-pressuring machines is reduced, i.e. the central part of the steel drum is pressed more deeply and the edge part is pressed more shallowly. Therefore, the compressed steel drum is not beneficial to orderly stacking, and the situation that the pressure head is wrapped by the steel drum and cannot be pulled out can also occur.
