Embodiment 1

[0029] A φ10 centrifugal extractor with a 40-stage drum diameter of 10mm was used to conduct a verification experiment of the TRPO process for removing actinides in high-level waste liquid in the equipment room, and the feed liquid used was real high-level waste liquid. There are 10 inlet materials and 7 outlet streams in the whole experimental system, and the flow rate of the outlet streams is 48m L / h. When starting the strong radioactivity experiment, start the 40-stage φ10 centrifugal extractors to make them run at 4200r / min, and feed each material liquid to the 40-stage centrifugal extractor system according to the set process flow rate. When the entire 40-stage centrifugal extractor system is When the outlet pipe 6 has liquid flowing out, the sampling of each outlet stream can be carried out. When sampling at each outlet, first place the sampling cups 9 on the placement holes 5 of the sampling cups on the slide 4 with a manipulator, and then use the manipulator installed ...

Embodiment 2

[0031] A φ10 centrifugal extractor with a 32-stage drum diameter of 10mm was used to conduct a verification experiment of the process flow for removing strontium and cesium elements in high-level waste liquid in the equipment room, and the material liquid used was real high-level waste liquid. There are 8 inlet materials and 5 outlet streams in the whole experimental system, and the flow rate of the outlet streams is 80m L / h. When starting the strong radioactivity experiment, start the 32-stage φ10 centrifugal extractors to make them run at 3800r / min, and then feed each feed liquid to the 32-stage centrifugal extractor system according to the set process flow rate. When the entire 32-stage centrifugal extractor system is When the outlet pipe 6 has liquid flowing out, the sampling of each outlet stream can be carried out. When sampling at each outlet, first place the sampling cup 9 on the placement hole 5 of each sampling cup on the slide 4 with the manipulator, and then move t...

Abstract

The invention provides a sampling device and method for material flows of each outlet of a multistage centrifugal extractor, belonging to the technical field of solvent extraction and sampling analysis. The device comprises the multistage centrifugal extractor, a mounting rack, a linear bearing, a guide rod, a slide plate, sampling cups and a liquid storage groove, wherein the linear bearing is mounted on the guide rod and the slide plate is installed on the linear bearing and is provided with a plurality of sampling cup holding holes. When liquids flow out from each outlet pipe of the multistage centrifugal extractor, a manipulator installed in an equipment room places the sampling cups in each hole in the slide plate, then moves the slide plate to approach each outlet pipe of the multistage centrifugal extractor so as to allow the liquids flowing out from each outlet pipe to flow into the sampling cups, and finally moves away the slide plate when preset sampling time is up. The sampling device provided by the invention is convenient to operate by the manipulator, realizes simple, reliable and high-efficiency operation, is applicable to sampling of material flows of each outlet during strong radioactivity experiments with a multistage centrifugal extractor system and provides conditions for acquisition of accurate data through the strong radioactivity experiments.

Description

technical field [0001] The invention relates to an outlet stream sampling device and method, in particular to an outlet stream sampling device and method for a multistage centrifugal extractor system used in strong radioactive experiments, and belongs to the technical field of solvent extraction and sampling analysis. Background technique [0002] The centrifugal extractor is a high-efficiency solvent extraction equipment that relies on strong centrifugal force to separate the phases of the two-phase mixed liquid. It has the advantages of fast state speed, convenient start and stop, no damage to the established steady state after parking, and easy remote control and maintenance. Therefore, it is very suitable for the strong radioactivity experimental verification of nuclear fuel reprocessing and high-level radioactive waste liquid separation. Has been widely used. When carrying out strong radioactivity experiments, the centrifugal extractors are connected in series in multi...
