Flow adjusting device and mixing-clarifying tank

Abstract

The invention provides a flow adjusting device and a mixing-clarifying tank. The flow adjusting device comprises a hollow cylinder body; a bottom plate, which is connected with the bottom of the cylinder body; a baffle plate, which is arranged in the cylinder body, is respectively connected with the bottom plate and the inner side wall of the cylinder body, and is lower than the cylinder body, wherein the baffle plate divides the internal space of the cylinder body into an inlet chamber and an outlet chamber, which are communicated with each other, the inlet chamber is provided with a fluid inlet, and the outlet chamber is provided with a fluid outlet; and an air pipeline, which is communicated with the top of the cylinder body. The cylinder body is connected with a pressure adjusting device through the air pipeline, so that the internal pressure of the cylinder body is adjusted through the pressure adjusting device, and the fluid flow is adjusted. The flow adjusting device can achievecontinuous and accurate adjustment of fluid flow by adjusting the pressure in the cylinder body, and has a good adjusting performance within a certain flow range. Moreover, the flow adjusting deviceis free of moving parts, free of maintenance and suitable for adjusting the conveying flow of a radioactive liquid.

Description

technical field [0001] The invention relates to the technical field of nuclear fuel reprocessing, in particular to a flow regulating device and a mixing and clarifying tank comprising the flow regulating device and a mixing and settling tank. Background technique [0002] In the field of nuclear fuel reprocessing, the equipment and pipelines used to process radioactive materials are installed in equipment rooms with thick concrete shielding walls. Therefore, the equipment should be maintained as little or maintenance-free as possible to improve the operational safety of reprocessing facilities and stability requirements. [0003] In order to meet the continuous and stable operation requirements of nuclear fuel reprocessing plants, some processes need to adjust or control the flow of feed liquid. However, due to the sealing structure and moving parts in the existing valves that need to be repaired, it is very important in nuclear fuel reprocessing plants. The application is ...
