Drying station in humid waste bin and drying method

Abstract

The invention discloses a drying station in a humid waste bin and a drying method, and relates to the technical field of radioactive waste treatment. The drying station comprises a drying chamber internally provided with a drying station, the drying station is used for feeding of the waste bin, and a sealing cover is arranged at the top of the drying station; and the sealing cover can move up and down relative to the drying station and is used for sealing or opening the waste bin placed on the drying station. The sealing cover special for sealing the waste bin is arranged in the drying chamber, and compared with a traditional treatment mode that a sealing cover is not additionally arranged and the waste bin is directly opened for drying, the problem that humid waste in the waste bin is diffused and splashed in the drying process can be effectively solved through the scheme; and gas containing radioactive liquid drops is prevented from diffusing into the drying chamber and a connected pipeline or equipment to cause damage to the equipment pipeline and radiation injury to related personnel.

Description

technical field [0001] The invention relates to the technical field of radioactive waste treatment, in particular to an in-barrel drying station and drying method suitable for radioactive wet waste. Background technique [0002] Nuclear energy, which is clean and unrestricted by weather conditions, makes it highly respected in the energy industry. At present, about 16% of the world's electricity is produced by nuclear reactors, and more than 40% of energy production in nine countries comes from nuclear energy. The International Atomic Energy Agency predicts that nuclear power will account for at least 25% of all power by 2030, and the maximum growth may reach 100%. However, some radioactive waste will inevitably be produced in the process of using nuclear energy to generate electricity. In order to protect human health and environmental safety, how to dispose of these radioactive waste is very important. [0003] Radioactive solid waste is one of the main types of radioacti...

Problems solved by technology

[0004] Super-compression technology is a technology for compressing and reducing the volume of radioactive solid waste. However, in some cases, part of the compressed waste is wet. up to 30%, and the existing general compression production line does not have the ability to compress waste with a free water content greater than 1%, which requires drying this part of the wet waste to reduce the free water content before it can be compressed and packaged
