Description
Technical Field
The invention relates to a pyrolysis device, in particular to a ball-milling pyrolysis device for treating radioactive organic waste, and belongs to the technical field of radioactive waste treatment.
Background
Radioactive pollutants are inevitably generated in nuclear power production, and a nuclear power station usually adopts super compression or pyrolysis gasification for volume reduction treatment, but the radioactive polluted ion exchange resin (namely waste resin) and radioactive waste tributyl phosphate/kerosene (TBP/OK) are treated by adopting a traditional incineration and super compression treatment method with higher treatment difficulty. Because the temperature is high during incineration, radioactive cesium and the like in the waste volatilize, so that generated gas and fly ash are polluted, a high-efficiency filtering system is needed for treatment, oxides of S and N can be generated due to the participation of oxygen in the combustion process, and the post-treatment of the two oxides is a difficult problem, so that the traditional incineration technology has no outstanding capacity in treating radioactive organic waste to avoid nuclide pollution. The traditional heat treatment technologies such as incineration and gasification have higher operation temperature, the volatilization of radioactive nuclides caused by the treatment of organic wastes is still inevitable, and the subsequent flue gas radionuclide removal treatment still faces huge pressure; the coefficient of the excess air in burning is high, and the smoke quantity is large. Therefore, the radioactive organic waste is treated by adopting a low-temperature pyrolysis method, the volatilization of radioactive nuclides is reduced, and the ash is enriched in the ash so as to be convenient for solidification.
The ball mill is a powder or slurry grinding dispersion devices, widely used in the electronic, chemical and material field, the ball milling process is a mechanical process, change the size and other characteristics of the material in the grinding process, the ball milling pyrolysis device is a device generally used in the field of biomass and coal pyrolysis, because the mechanical activation and convenient auxiliary heating mode of the pyrolysis process have the advantages of high pyrolysis efficiency, simple equipment and high maintenance cost, and the ball milling pyrolysis device is applied to the field of radioactive organic waste treatment in recent years. The existing ball-milling pyrolysis device applied to radioactive organic waste treatment is mainly in the mode of easy vertical arrangement and mechanical stirring, and has the defects of difficult bottom slag discharge, small ball blockage, high equipment abrasion, high operation noise and the like in the operation process.
For example, CN112013402A, "ball-milling pyrolysis activation furnace", this patent sets up three temperature-associated zones to control the temperature, sets up stirring rake and (mixing) shaft to realize the ball-milling process, and its shortcoming is that the dwell time of material in different temperature zones is difficult to control, and it is great to lean on mechanical stirring drive pellet equipment loss, and the stirring rake is easy to wear and tear, warp, though the bottom has increased the sieve and has prevented the pellet jam, the problem that the effect of slagging off is still piled up to pellet bottom can still appear when the rotational speed is not big enough. Considering that fluidization of grinding balls in a ball milling device has high requirements on mechanical strength of equipment, the grinding balls can cause difficult slag discharge and the like, ceramic or metal grinding balls are omitted from arrangement in some patent designs, or the arrangement form of a ball milling pyrolysis furnace is improved. For example, WO2020/089341A1, "system and method for pyrolyzing organic waste", which is an improvement on the basis of a rotary ball-milling pyrolysis reactor, eliminates ceramic metal balls, simplifies the system design, but has the disadvantages that the crushing effect is inferior to that of ball-milling grinding due to close mechanical stirring, the rotation speed of mechanical stirring is slow, partial coking phenomenon may occur due to loss of heat conduction of the blended grinding balls, and the requirement of the temperature of about 500 ℃ on the internal mechanical structure is still high. CN103140569A "method and system for grinding pyrolysis of granular carbonaceous feedstock", which adjusts the grinding pyrolyzer to a horizontal arrangement, the whole grinding pyrolysis container is a rotatable, non-agitated mechanical structure, and the disadvantage is that the horizontal arrangement of the grinding pyrolyzer does not discharge slag smoothly, and the whole container rotation is not favorable for equipment and line arrangement.
Therefore, how to ensure the pyrolysis efficiency of the ball-milling pyrolysis device and reduce the abrasion in the operation process of equipment, the convenience in discharging slag of pyrolysis ash slag and the reduction of nuclide volatilization through temperature control guarantee are the problems of the ball-milling pyrolysis device for treating radioactive organic wastes which need to be considered in a key way.
