Embodiment Construction

[0033] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 and figure 2 As shown, a method for fixing pulse baffle column plate strings of the present invention is applied to the purification process of natural uranium in the nuclear fuel cycle, comprising the following steps:

[0035] (1) Determine the main components

[0036] The baffle includes an inner ring plate and an outer ring plate;

[0037] When the pulse column is equipped with baffle plates, the inner ring plate and the outer ring plate are assembled into several plate strings in a certain order;

[0038] The main components of the fixed plate string are: central column, spacer tube Ⅰ, tie rod Ⅰ, spacer tube Ⅱ, tie bar Ⅱ, distance tube Ⅲ;

[0039] The function of spacer tube I, spacer tube II and spacer tube III is to support and fix the baffle plate, and at the same time separate the...

Abstract

The invention belongs to the technical field of a nuclear fuel circulating natural uranium purification process and particularly relates to a fixing method of a pulse baffle column plate string. Meanwhile, fixation between baffles is enhanced through adopting a self-gravity effect of the baffles. Compared with other fixing methods including traditional welding and the like, an active fixing method is adopted, so that the linearity and concentricity between a central column and the plate string are effectively reduced. A distance sink tube guarantees that the distance between the baffles is strictly equal, so that the whole fixation of each baffle is facilitated and an easy-to-move part is not adopted; and fluid can conveniently and regularly flow in a baffle pulse column, and the stability and the two-phase mass transferring effect are enhanced.

Description

technical field [0001] The invention belongs to the technical field of nuclear fuel cycle natural uranium purification technology, and in particular relates to a method for fixing pulse baffle column plate strings. Background technique [0002] At present, the extraction equipment used in the nuclear field mainly includes three types: mixing and settling tank, centrifugal extractor and pulse extraction column. Due to the large floor area of ​​the mixing and settling tank, it is not easy to remove dirt and other defects; the centrifugal extractor has the disadvantages of difficult maintenance and complex equipment structure, etc. These two kinds of extraction equipment are gradually replaced by pulse extraction columns. [0003] At present, the pulse extraction columns commonly used in the field of nuclear technology at home and abroad mainly include sieve plate, baffle plate, and nozzle plate pulse column. The sieve plate column was used in the early stage, but it was gradu...
