A resin automatic loading and unloading system and method for radioactive environment

Abstract

The present invention proposes an automatic loading and unloading system for waste resin in a radioactive environment, which includes an ion exchange column, and also includes: a feeding device for pumping fresh resin into the ion exchange column; an unloading device, including a filter barrel with an upward opening, The filter barrel is detachably installed with a filter screen for filtering waste resin and containing waste resin. The filter barrel is connected with the ion exchange column, and is used to discharge waste resin into the filter barrel and filter the waste resin; transfer device, transfer The device includes a gripper assembly, a lifting assembly and a transfer assembly, the gripper assembly is used to grab and release the filter, the lifting assembly is used to drive the gripper assembly to move in the vertical plane, and the transfer assembly is used to drive the gripper assembly on the horizontal plane movement within; a waste collection unit for storing waste resin and filter screens released from the gripper assembly; and a stand for supporting the transfer unit. It can conveniently realize the automatic transfer of the waste resin discharged from the ion exchange column.

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...

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.
