Description
The present invention relates to a kind of radioactivity or toxic waste method for packing, refer to utilize vacuum sealing technique or isolated packing technique especially, will a kind of radioactivity or the toxic waste method for packing of the canister sealing of radioactivity or toxic waste be housed.
In order to prevent radioactivity nuclear species in the radioactive waste or toxic waste such as mercury mud contaminated environment, and biology to be damaged, need to handle radiation waste material or toxic waste such as mercury mud, change it into determine form, promptly solidified.Sodium sulphate concentrate and powdered resin and filtration residue that present domestic nuclear energy power plant is produced adopt the cement solidification method to handle; Toxic waste such as mercury mud also adopt the cement solidification method to handle; The high radioactivity waste material is then handled with the glass solidification method; Radioactivity of solidifying or toxic waste such as mercury mud make contained radioactivity nuclear species or toxic waste such as the contained mercury of mercury mud through after the suitable packing, can't disengage in waste material; To pack radioactive waste or toxic waste such as mercury mud after handling again, and be sent to relay station and carried out intermediate time scale storage 40 years to 70 years, and seek the deep stratum that to avoid polluted underground water again and finally handle and store up.Each advanced country of the world handles radioactive waste at present, all only proceeds to the stage of storing in the relay station, for selected last disposal site, avoids contamination, and is all extremely careful.But the design of storing the relay station of radioactivity or toxic waste and final disposal field mat multiple combination obstacle is blocked and is disengaged the radioactivity nuclear species from radioactive waste and further be discharged in the external environment, or prevent that toxic waste such as mercury mud from disengaging the mercury pollution environment, guaranteeing in the long-term process of putting, unlikely environmental quality and human lives's safety are caused bad influence.
So-called multiple combination obstacle comprises radioactive waste firming body, steel vessel, sand-cement slurry, padded coaming, reinforced concrete, backfilling material, earthing, pumping equipment and vegetation etc.; Wherein padded coaming adopts tool low water permeability and high adsorption material, its effect has two, the one, utilize its low water permeability, make outside infiltration be difficult for intruding into the waste material firming body, the 2nd, even outside infiltration intrudes into the waste material firming body, the radioactivity nuclear species that is disengaged can utilize its high characterization of adsorption to be adsorbed, and makes nuclear species be difficult for migrating to media such as underground water.Japan adopts and is commonly called as bentonitic clay as padded coaming, and Taibei rapid transit engineering also adopts this type of clay to come sealing.
Through looking into, relay station or final disposal field set firmly multiple combination obstacle and block and disengage the radioactivity nuclear species from radioactive waste and further be discharged in the external environment, or prevent that toxic waste from oozing out contaminated environment.Only look into, at present countries in the world will be packed active steel vessel and be left relay station in, maybe will pack the steel vessel of toxic waste, leave the final disposal field in, behind the normal underground water and the long-term erosion of air of finding to be infiltrated, the underground water of infiltration continues dipping radioactivity or toxic waste and also dissolves radioactivity or toxic waste, continue to infiltrate padded coaming, eventually to saturated and ooze out relay station or final disposal field, polluted underground water source, plant and people and animals form environment and people and animals' great calamity.
In view of this, the present invention provides a kind of radioactivity or toxic waste method for packing, enables long-term safety storage of radioactive or toxic waste.
Fundamental purpose of the present invention can prevent that moisture content and air from corroding a kind of radioactivity or the toxic waste method for packing of the canister that radioactivity or toxic waste are housed providing.
Another object of the present invention providing utilization vacuum-packed or isolated packing, corrodes a kind of radioactivity or the toxic waste method for packing of the canister that radioactivity or toxic waste are housed to prevent water and air.
The present invention is as follows in order to the technical scheme that realizes above-mentioned purpose:
A kind of radioactivity or toxic waste method for packing; it is characterized in that radioactivity or toxic waste compression or curing; and after being installed on canister; being packaged in inside again is in the reinforced plastic bucket of vacuum shape; or directly outside device has the canister of radioactivity or toxic waste; coating one reinforced plastic top layer is to protect this canister appearance.
The invention provides a kind of vacuum sealing technique or isolated packing technique of utilizing, to a kind of radioactivity or the toxic waste method for packing of the canister sealing of radioactivity or toxic waste be housed, utilize this method to enable effective long-term security ground and preserve and to have solidified or uncured poisonous or radioactive waste, unlikely environment and human lives's safety are caused harmful effect.
Exemplify specific embodiment below and further describe the present invention.
Embodiment establishes a suitable reinforced plastic bucket and the plastic cement bung that can pack one 55 gallons of zinc-plated steel drums, the radioactive waste (or toxic waste such as mercury mud) that has solidified is equipped with in these 55 gallons of zinc-plated steel drum inside, these 55 gallons of galvanized steel barreleds are gone in this reinforced plastic bucket, again this plastic cement bung is positioned on the bung of this reinforced plastic bucket, and this plastic cement bung is engaged with the bung of this reinforced plastic bucket with high frequency (cycle) machine, when this plastic cement bung will soon engage fully with the bung of this reinforced plastic bucket, utilize the vacuum machine with the air sucking-off in this reinforced plastic bucket, when forming the vacuum shape in this reinforced plastic bucket, utilize High-frequency machine that this plastic cement bung is engaged fully with the bung of this reinforced plastic bucket, finish encapsulation, make 55 gallons of zinc-plated steel drum appearances being packaged in this reinforced plastic bucket can secluding air and moisture content, therefore do not corrode, and the energy long-term security is preserved the radioactive waste of curing (or toxic waste such as mercury mud) of these 55 gallons of zinc-plated steel drum interior arrangements.
In the foregoing description, be equipped with outside 55 gallons of zinc-plated steel drums of radioactive waste inside, also direct coating one reinforced plastic top layer, and its method is as follows:
One, granular reinforced plastic material is placed in the extruder; first with suitable temperature through kneading; be sprayed directly on to 55 gallons of zinc-plated steel drum outer rims that radioactive waste is equipped with in inside by a slot nozzle with sheet type then; form the reinforced plastic top layer of a suitable thickness, to protect these 55 gallons zinc-plated steel drum appearances.
Two, 55 gallons of zinc-plated steel drums that this are equipped with radioactive waste directly are soaked in the reinforced plastic solution, make this that 55 gallons of zinc-plated steel drum outer rims of radioactive waste are housed, form reinforced plastic top layer, this reinforced plastic top layer and this 55 gallons of complete driving fits of zinc-plated steel drum surface of a suitable thickness.
In the foregoing description, the toxic waste such as the mercury mud of being packed in these 55 gallons of zinc-plated steel drums, if not earlier through solidifying, also can utilize a reinforced plastic bag earlier this toxic waste such as mercury mud to be carried out vacuum packaging, reinstall in these 55 gallons of zinc-plated steel drums, and outside these 55 gallons of zinc-plated steel drums coating one reinforced plastic top layer, can prevent the toxic waste of this uncured such as the airborne oxygen of mercury mud, mercurous moisture content wherein and these 55 gallons of zinc-plated steel drum inside equally, corrode these 55 gallons of zinc-plated steel drums for a long time and ooze out; And can prevent final disposal moisture content and air 55 gallons of zinc-plated steel drums corroding this packed into toxic waste such as mercury mud outside the venue for a long time, can effectively increase the storage safety of the toxic waste such as the mercury mud of this uncured.
