Abstract

The invention discloses a cement solidification system and method for radioactive waste treatment and application. The system comprises a three-axis rail car, a rail, a scale detection system and a wireless control system. The three-axis rail car comprises a horizontal moving system, a vertical lifting system and a rotating system, the horizontal moving system, the vertical lifting system and therotating system respectively comprise a motion speed reducer, a lifting speed reducer or a rotating speed reducer, and the three-axis rail car is controlled by the wireless control system to move on arail and realize lifting and rotating. The scale detection system is used for detecting the position of the three-axis rail car on the rail in real time. The wireless control system is used for receiving the position information, detected by the scale detection system, of the three-axis rail car and judging whether the motion speed reducer or the lifting speed reducer or the rotating speed reducer is started or not according to the detected position information. According to the invention, the problems of high equipment cost, complexity and poor applicability caused by adoption of a cement solidification line in treatment of radioactive wastes in the prior art are solved.

Description

Technical field [0001] The invention relates to the field of radioactive waste treatment, in particular to a cement solidification system, method and application for radioactive waste treatment. Background technique [0002] The radioactive cement solidification line is a production line system for processing wet radioactive waste. The treated wet radioactive waste forms a uniform and stable cement solidification body. [0003] At present, the existing cement curing line in the country uses roller conveyors for the curing barrel, including: 5-8 sets of straight roller tables, 1-2 sets of turning roller tables, 1-2 sets of rotating roller tables, and 1-2 sets of mechanical jacking equipment / Or hydraulic jacking roller table, 2 sets of positioning equipment, 2 sets of clamping equipment, 2 sets of barrel blocking mechanism, multiple sets of signal detection devices and control systems. Straight roller table is used for conveying cement curing barrel; turning roller table is used f...
