DEVICE OF PRODUCING CEMENT LINING WITHIN DRUM BY USING SUPERCRITICAL CARBON DIOXIDE

摘要

Purpose: the equipment for generating a cement lining is arranged to reduce the improved existing time into five days and obtains a product, with excellent water permeability and a feature, radioactive waste, such as a cured body of the intensity of pressure is used as to need. Construction: a gas booster (20) can be pressurized carbon dioxide, and a certain amount of pump (40) can accurately be pressurized and adjust flux. A radiator (30) before through constant displacement pump makes carbon dioxide become a kind of liquid and sends it to constant displacement pump. Here, the carbon dioxide stream of a carbon dioxide reaction room (50) and by continuously pump improve its pressure reach a supercriticality. It is used to help that there is a steel mesh with the mold of the carbon dioxide of a cement lining reacted. When accelerating the hardening of cement by using carbon dioxide, the pressure for being applied to dioxide is 73.8 to 180 bars, and temperature is 0 to 70 deg.C.
