Embodiment

[0026] refer to figure 2 , shows a schematic diagram of a novel ideal separation cascade device of the present invention, said device comprising:

[0027] Multiple sets of separation machines, which are connected in parallel in a pyramid form from top to bottom; the feed input to each set of separation machines is divided into fine material and lean material output; the input of the separation machine in the next row is its In the pyramid, it corresponds to the output of the previous line of separation units; for a certain group of separation units, if the abundance of the input stream is c f , then the concentration concentration output by the single separation machine and lean material abundance Among them, α and β separate the enrichment separation coefficient and depletion separation coefficient of a single machine, respectively.

[0028] exist figure 2 Each circle in represents a node, and each node represents a group of parallel separate stand-alone machines.

Abstract

The invention provides an ideal separation cascade unit. As a structure in isotope separation equipment, the cascade unit comprises a plurality of separation signal machines; the plurality of separation signal machines are connected in parallel row by row from top to bottom in a pyramid mode; feed input to each separation single machine is classified into beneficiated material and lean to be output; the input of the separation single machine in the next row is the output of the corresponding separation single machine in the previous row in a pyramid; for a certain separation single machine, if the abundance of input material flow is cf, the abundance of the beneficiated materials and the abundance of the leans output by the separation single machines are shown in the specification, wherein alpha and beta respectively refer to the concentration separation factor and the dilution separation factor of the separation single machines. The invention ensures that the separation cascade unit can work in an ideal cascade state when using the separation single machine with any separation factor.

Description

technical field [0001] The invention relates to the technical field of isotope separation equipment, in particular to a novel ideal separation cascade device. Background technique [0002] In the diffusion and centrifugal isotope separation technology, the separation unit must be connected in series and parallel in some form to form a separation device that meets the requirements. This separation device is called a separation cascade. In isotope separation, countercurrent cascade is the most common form of cascade. Its biggest feature is that the lean material (or heavy fraction) of a certain level will be returned to a certain level below as a feed. Refer to figure 1 Shown is a section of one form of countercurrent cascade. [0003] figure 1 Middle F i , P i , W i Respectively represent the supply material, concentrate material and lean material of the i-th stage. It can be seen from the figure that the supply of the i-th stage is composed of the fine material of the ...
