Description
The invention belongs to radioactive solid waste treatment process and equipment thereof, be specifically related to a kind of radioactive solid waste burning process and specialized equipment thereof.
At present, burning is one of effective method of handling radioactive solid waste, flammable radioactive waste makes organism become inorganics after burning disposal, can farthest reduce the refuse volume, greatly reduce the disposal expense of refuse, increase the security of disposal process, avoided the harm that environment is caused.
CONF-930906 nuclear waste management in promptly 1993 and ambient compensation international conference are recorded the 3rd volume and have been delivered the report of a piece " handling radioactive waste CIU running test " (Operational experience of the Juelichincineration system in the treatment of radioactive waste) about ambient compensation and environmental management problem P301～P304, have introduced the burning process and the system equipment of Juelich laboratory processing radioactivity combustible waste in the literary composition.Its to the effect that refuse send into glove box through the twice gate valve, send on the upper fire-grating of pyrolysis oven the noncombustibles barrelling through combustible after the hand-sort.Light a fire in the pyrolysis oven centre position.Enter from a wind of cold air and the flue gas top by pyrolysis oven, flue gas is drawn under the upper fire-grating and is delivered to second firing chamber (stove) burning after the auxiliary air of sending into mixes.Secondary air is sent into pyrolysis oven by upper and lower fire grate respectively.Upper fire-grating drops to the ash and the carbon residue of lower fire grating, and the secondary air of being sent into by fire grate burnouts.Remove acidic gas in flue gas through three sections gas-gas heat exchange cooling after enter scrubber after whirlwind, bag filter and the high efficiency particulate air filter dust removal by filtration by the flue gas that comes out in second firing chamber, send into smoke stack emission by induced draft fan at last.
It is unreasonable that the shortcoming that this Processes and apparatus exists is discussed its pyrolysis oven design for the present, causing in the waste pyrolysis process air-flow trend is from top to bottom, do not meet correct pyrolysis principle, the grieshoch of promptly from bottom to top arranging, burn the pyrolytic process of layer, pyrolytic layer and preliminary heating zone; This technology is burnt pyrolysis gas at twice, when particularly in pyrolysis oven, burning for the first time, auxiliary air is sent into from fire grate, be difficult to mix fully with pyrolysis gas, cause portion of hot to be vented one's spleen owing to do not obtain sufficient oxygen and produce unburnt soot in the high-temperature region, though in second firing chamber, can burn away, in case producing, soot is difficult to be burnouted, do not reach the purpose of perfect combustion.In addition, its major defect is that the cooling of flue gas is to adopt the gas-to-gas heat exchanger type of cooling, whirlwind, bag filter and high efficiency particulate air filter dust collection method are adopted in the udst separation of flue gas, this cooling, purification style mainly are applicable to the radioactivity combustible waste of burning disposal pure natural fiber element, are not suitable for the radioactivity combustible waste that burning disposal contains a large amount of plastics and rubber.Because contain metals such as lead, zinc in the adjuvant of plastics and rubber, burn lead, zinc chloride and the oxide micronic dust that can produce a large amount of viscosity under the chloride effect in the flue gas of back, in flue gas cooling and udst separation process, can stick on interior pipe, filter bag and the high efficiency particulate air filter of heat exchanger, reduce their cooling, filtration efficiency, even make it stop up inefficacy.And plastics and rubber also can produce three, four benzene pyrenes after burning with toxic gases such as Er Evil , does not have to purify accordingly the measure and the equipment of this type of toxic gas in existing processes and the equipment.The existing radioactivity combustible waste situation of China is the classification that does not have standard at present, contains a large amount of plastics and rubber in the refuse, brings difficulty for after burning the cooling and the purification of flue gas.
