Abstract

The invention relates to treatment equipment for radioactive contamination materials and provides a radioactive waste cement solidification line in order to solve the domestication problem of a radioactive waste cement solidification line. The radioactive waste cement solidification line comprises a stirring device, a cement conveying pipeline, a dry material filling cover, a wet material filling cover, a fixed platform, a cleaning liquid recovery device, a waste filter element barreling device, a waste barrel horizontally-moving device, a first waste barrel laterally-moving device, a stacking roller way, a second waste barrel laterally-moving device, a standby waste barrel horizontally-moving device, a standby roller way and two sets of lifting devices. The radioactive waste cement solidification line has the high automation level and reliability, and is high in solidification work efficiency and convenient and rapid to operate; multiple waste barrels can simultaneously enter work, cement solidification of multiple kinds of radioactive waste such as radioactive concentrated liquid, radioactive waste resin and radioactive waste filter elements, and a reliable guarantee is provided for treating the radioactive waste in China.

Description

technical field [0001] The invention relates to a treatment equipment for radioactive contaminated materials, in particular to a radioactive waste cement solidification line. Background technique [0002] In the field of nuclear industry, the operation of nuclear facilities will produce corresponding radioactive waste. Taking nuclear power plants as an example, liquid and solid radioactive waste will be generated during its operation, such as radioactive concentrate, radioactive waste resin, radioactive waste filter element, maintenance waste, etc. Because these wastes are radioactive, they need to be immobilized to meet relevant requirements. [0003] There are many kinds of solidification methods for radioactive waste. Among them, cement solidification technology is widely used in radioactive waste treatment in various occasions because of its early development, mature technical route and wide application range. It is very suitable for solidification of liquid and solid r...
