Automatic loading and unloading system for resin and method used in radioactive environment

Abstract

The invention provides an automatic loading and unloading system for waste resin in a radioactive environment, which comprises an ion exchange column, and further comprises a loading device for pumping fresh resin into the ion exchange column; a discharging device which comprises a filtering barrel with an upward opening, wherein a filtering net used for filtering waste resin and containing the waste resin is detachably installed in the filtering barrel, and the filtering barrel is communicated with the ion exchange column and used for discharging the waste resin into the filtering barrel andfiltering the waste resin; a transferring device which comprises a gripper assembly, a lifting assembly and a transferring assembly, wherein the gripper assembly is used for gripping and releasing thefiltering net, the lifting assembly is used for driving the gripper assembly to move in a vertical plane, and the transferring assembly is used for driving the gripper assembly to move in a horizontal plane; a waste collecting device which is used for storing the waste resin released by the gripper assembly and the filtering net; and a bracket which is used for supporting the transferring device.The automatic transfer of the waste resin discharged from the ion exchange column can be conveniently realized.

Description

technical field [0001] The invention relates to the technical field of nuclear chemical processing equipment, in particular to an automatic resin loading and unloading system and method used in a radioactive environment. Background technique [0002] With the rapid development of the nuclear industry in recent years, a large amount of radioactive waste has been produced. If it is not handled properly, it will seriously affect the environment and human safety. In the radioactive "three wastes", the volume of radioactive waste water and the total amount of radioactivity contained in it It accounts for a very large proportion of the total amount of radioactive waste, so the treatment of radioactive waste water is particularly important. [0003] Ion exchange method is a treatment process with strong selectivity and purification ability. It has been widely used in the treatment of radioactive wastewater in the nuclear industry. The principle is to use the exchangeable ion charac...

AI Technical Summary

Problems solved by technology

However, according to the requirements of safety protection, the ion exchange resin and its equipment used for radioactive wastewater treatment should be installed in the equipment room with shielding function. At the same time, the ion exchange resin that concentrates a large amount of radioactive ions has strong radioactivity, which will cause serious damage to the replacement of the resin. It is very difficult and does not have the conditions for manual operation

In addition, ion exchange resins are usually spherical particles with a diameter of 0.4-0.6 mm. The small size and spherical shape make conventional mechanical transport mechanisms inconvenient.
