Description
Technical field
The invention belongs to the radioactive waste process field of nuclear power station, more particularly, the present invention relates to a kind of replacing conveyer method of nuclear power station Spent Radioactive filter cartridge and change transporter.
Background technology
The filter cartridge type filter that nuclear power station adopts can produce the Spent Radioactive filter cartridge at run duration, these useless filter cartridges often have higher surface dose rate, in case be exposed in the environment, may to environment disperse or migration, cause the pollution to environment.Filtrator in the use generally is installed in the cavity body structure with shielding action, when filter cartridge does not take out, with radioactive filter cartridge with flow through the radioactive fluid of filtrator under the shielding action of shielding cavity structure, its radioactivity can not spread to the external world; Behind the filter failure, the Spent Radioactive filter cartridge of generation need be changed taking-up, then is transported to the Solid Waste Treatment line and does to process further, and useless filter cartridge should remain that radioactivity does not expand in the environment in changing transport process.
For the ease of the filter cartridge of all filtrators is changed and is transported, the filtrator of existing each system of nuclear power station all centralized arrangement in room, same hall.Be provided with a plurality of filterhouses for filtrator is installed in the room, hall, around each filterhouses and bottom is the wall body structure with screening ability, and the filterhouses top then is the filtrator top cover.The central part of filtrator top cover is provided with a shield plug to be opened/closed, and the shield plug edge offers a shield opening that can stretch into to open and close for rod tool the filtrator top cover.After the filtrator top cover of filterhouses installs, generally no longer mobile within the phase in nuclear power station longevity, but the shield plug in the middle of the cover plate can remove and retract by crane, so that by the give up replacing of filter cartridge of shielding consent.
Existing nuclear power station is generally changed transporter by crane and filter cartridge useless filter cartridge is changed transhipment, concrete steps are: 1) operating personnel utilize rod tool to insert the shield opening that filter top covers, and open the filtrator top cover by the extruding switchgear; 2) after operating personnel's shield plug that hoist lifting hook and filter top are covered is connected, shield plug is removed; 3) after the suspender of hoist lifting hook and filter cartridge being changed the transporter top is connected, filter cartridge is changed transporter to be sling, and be transported to the top of filtrator top cover, make filter cartridge change the guide collar of transporter bottom and the shielding consent centering that filter top covers, again filter cartridge is changed transporter peace seat and covered in filter top; 4) by the control box of operation filter cartridge replacing transporter, open the lock gate hatch that filter cartridge is changed the transporter bottom, the control gripping apparatus descends and grasps useless filter cartridge, and the bottom lock gate hatch is closed in the rising of control gripping apparatus afterwards after the crawl; 5) utilize crane that filter cartridge is changed transporter and sling, and be transported to useless filter cartridge decline passway top; 6) open filter cartridge and change transporter bottom lock gate hatch, the control gripping apparatus descends, and useless filter cartridge is released in the transfer container of decline passway below; 7) filter cartridge that will give up transports the Solid Waste Treatment line to and is for further processing; 8) new filter cartridge is installed in the filtrator, closes the filtrator top cover; 9) utilize crane that shield plug is retracted the filterhouses filter top again and cover locking.
Although existing above-mentioned replacing conveyer method can satisfy the replacing demand of useless filter cartridge, but still have following technological deficiency: 1) automatization level is not high, and part operation needs operating personnel's manual operation: opening of filtrator top cover needs operating personnel to utilize at the scene manual operation of rod tool; The filterhouses shield plug remove and retract operation, need operating personnel manually hoist lifting hook to be connected with shield plug and disconnect; Filter cartridge is changed transporter before transhipment and after the transhipment, needs operating personnel manually hoist lifting hook to be connected with filter cartridge replacing transporter and disconnects; 2) radiation protection design is rigorous not, there is certain radioactivity diffusion, the exposure dose of radiation that causes perform region and operating personnel to bear is larger: after the shield plug that the filterhouses filter top covers removes, be with outside radioactive useless filter cartridge can be exposed to, increased the radiation dose rate of perform region; After shield plug removes, before the useless filter cartridge taking-up, need operating personnel to disconnect at the scene being connected of shield plug and hoist lifting hook, and hoist lifting hook and filter cartridge are changed transporter be connected, these manual operations at the scene will make operating personnel be subject to larger radiation irradiation.
In view of this, a kind of nuclear power station Spent Radioactive filter cartridge that can solve the problems such as existing automation technolo degree is not high, radiation protection design is rigorous not of necessary exploitation is changed conveyer method and is changed transporter.
Summary of the invention
