Ash discharging device for alpha waste incineration ash

Abstract

The invention relates to a device for treatment of radioactive waste, in particular to an ash discharging device for alpha waste incineration ash. The ash discharging device structurally comprises an ash bin, an ash discharging operating box and a control system. The ash discharging operating box comprises an auxiliary in-bin box, a main ash discharging box and an auxiliary out-bin box. The auxiliary in-bin box is of a double-layered sealed chamber structure, and is provided with a bin-lifting mechanism and a bin-pushing cylinder. A buffer tank connected with an ash discharging pipe is arranged on the main ash discharging box and is connected with a weighing sensor, and a cover suction mechanism is further arranged in the main ash discharging box to drive moving carts, moving among the stations, of the ash bin. The auxiliary out-bin box is of a double-layered sealed chamber structure, a bin-forking mechanism used for transferring the ash bin from the main ash discharging box is arranged in the auxiliary out-bin box, and a bin-lifting mechanism and an outer-cover inlet are arranged above the bin-forking mechanism. By the ash discharging device, labor intensity of operators can be alleviated, irradiation degree of the operators can be reduced, and safety of ash discharging operation can be improved.

Description

technical field [0001] The invention relates to a device for treating radioactive waste, in particular to a discharge device for treating α waste after incineration. Background technique [0002] The incineration ash produced after the incineration of radioactive waste must be safely discharged from the incinerator before the subsequent preparation and disposal of the incineration ash can be carried out. The ash discharge process of ordinary radioactive waste incineration is generally: in the ash discharge glove box through the ash discharge valve Put the incineration ash into a plastic bag and put it in a bucket; or directly discharge the incineration ash into the ash bucket through the ash discharge valve and soft connection pipe. The ash bucket is generally a 100-200L container, and the ash discharge valve, glove box and The ash bucket connects the door cover and the flexible connecting pipe, which has the disadvantages of relatively inconvenient operation, high strength,...

The ash discharge process of ordinary radioactive waste incineration is generally: through the ash discharge valve in the ash discharge glove box Put the incineration ash into a plastic bag and put it in a bucket; or directly discharge the incineration ash into the ash bucket through the ash discharge valve and a soft connection pipe. The ash bucket is generally a 100-200L container, and the ash discharge valve, glove box and The ash bucket connects the door cover and the flexible connecting pipe, which has defects such as relatively inconvenient operation, high strength, high exposure dose to personnel, and easy contamination inside the glove box.
