Abstract

The invention provides an online purification device for liquid heavy metals. The online purification device comprises a purification tank, a purification pipeline and an expansion tank, the bottom ofthe purification tank is connected with the middle of the purification pipeline through a first pipeline, and an expansion tank is arranged at the upper end of the purification pipeline and sealed through an expansion tank flange. A blowing pipeline is arranged in the purification pipeline, one end of the blowing pipeline extends into the bottom of the purification pipeline, the other end of theblowing pipeline penetrates through the expansion tank flange and is connected with a second high-pressure gas cylinder through a second gas circuit, the lower end of the purification pipeline is connected with the lower end of the main loop pipeline through a third pipeline, and the upper portion of the side wall of the purification tank is connected with the upper end of the main loop pipeline.According to the online purification device for the liquid heavy metal, a method of combining filtering purification and blowing purification is adopted for removing the liquid heavy metal, online purification is achieved, operation of a main loop is not affected when the purification device stops operating after impurity removal, and the purification effect is improved. The invention further provides a using method of the online purification device for the liquid heavy metal.

Description

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