Abstract

The invention provides an on-line purification device for liquid heavy metals, comprising a purification tank, a purification pipeline and an expansion tank; the bottom of the purification tank is connected to the middle of the purification pipeline through a pipeline, the upper end of the purification pipeline is provided with an expansion tank, and the upper end of the expansion tank adopts an expansion tank. The tank flange is sealed; there is a blowing pipe in the purification pipe, one end of the blowing pipe extends into the bottom of the purification pipe, and the other end passes through the flange of the expansion tank and is connected to the high-pressure gas cylinder two through the second gas path, and the lower end of the purification pipe is The third pipe is connected to the lower end of the main circuit pipe, and the upper part of the side wall of the purification tank is connected to the upper end of the main circuit pipe through the second pipe. The liquid heavy metal online purification device of the present invention adopts the method of combining filtration purification and air blowing purification to remove, which not only realizes the online purification, but also does not affect the operation of the main circuit when the purification device is stopped to remove impurities, thereby improving the purification effect. The present invention also provides a method for using the liquid heavy metal online purification device.

Description

technical field [0001] The invention belongs to the technical field of liquid heavy metal purification, and in particular relates to a liquid heavy metal online purification device and a use method thereof. Background technique [0002] Liquid heavy metals mainly include lead, lead-bismuth alloys and other lead-based alloys. Liquid heavy metals have become the first choice for a new generation of nuclear reactor coolants due to their low melting point, high boiling point, high thermal conductivity and good safety, such as accelerator-driven subcritical systems ( ADS) selects lead-bismuth eutectic (LBE) as the reactor coolant, and selects lead as the coolant in lead-based reactors. When liquid heavy metals are used as coolants in reactors, the main problem is that they severely corrode structural materials. The main corrosion methods include oxidation corrosion, erosion corrosion, dissolution corrosion, etc. In order to prolong the service life of structural materials and red...
