Description
Technical field
The utility model belongs to Radioactive waste management field, in particular to one of the field in it is low put it is flammable solid
Radioactivity high-temperature flue gas quenching apparatus used in body waste calcining facility exhaust treatment system.
Background technique
Radioactive waste incineration technology is to handle one of most effective technology of radioactivity combustible waste in the world at present, by
The states such as the U.S., France, Germany, Japan are widely used.But incineration of waste treatment process is one of important occurring source of dioxin,
Referred to as " the strongest poisonous substance of toxicity on the earth ".The emission control of the toxicant has obtained domestic and international most attention, discharge
Standard is also increasingly tighter.Therefore, it to prevent the dioxin in high-temperature flue gas from generating again, needs to use cooling device by high temperature cigarette
Gas moment, (in 1s) was down to 200 DEG C or less.
Utility model content
Technical problem to be solved in the utility model is just to provide one kind can be directly high by 800 DEG C or so of radioactivity
Warm flue gas is directly cooled to 75 DEG C or so of radioactivity high-temperature flue gas quenching apparatus.
The utility model adopts the following technical solution:
A kind of radioactivity high-temperature flue gas quenching apparatus, the device include shell, shell top setting air inlet,
Gas outlet is arranged in bottom, thes improvement is that: upper at the top of the inner wall of shell to install cyclic annular water pipe, the ring-type water pipe and shell
The water inlet of side wall communicates, and is evenly distributed with more than two pressure atomization spray heads at equal intervals on cyclic annular water pipe.
Further, the nozzle of the pressure atomization spray head is vertically directed at the bottom wall of shell.
Further, air inlet is communicated with the exhaust outlet of radioactive waste incinerator dual firing chamber.
Further, gas outlet is communicated with the air inlet of deacidification dust-extraction unit.
A kind of radioactivity high-temperature flue gas quick cooling method is theed improvement is that using above-mentioned device: the cooling outside shell
Water is flowed into after cyclic annular water pipe by water inlet to be sprayed from the pressure atomization spray head on cyclic annular water pipe, is formed in space inside housings
Cyclic annular, uniform, top-down subtle water droplet net, radioactivity high-temperature flue gas by the air inlet of case top enter after shell with
The intracorporal subtle water droplet net of shell carries out heat and mass, and the heat in radioactivity high-temperature flue gas is by the subtle water droplet in subtle water droplet net
Instant vaporization evaporation, so that radioactivity high-temperature flue gas be made to cool down rapidly, the radioactivity flue gas after cooling is discharged from gas outlet, does not steam
The cooling water that hair falls also is discharged from gas outlet.
Further, it is discharged after radioactivity high-temperature flue gas is cooled to not higher than 75 DEG C in shell from gas outlet.
Further, the temperature fall time of the radioactivity high-temperature flue gas is no more than 1s.
Further, the cooling water is tap water.
The beneficial effects of the utility model are:
Quenching apparatus and quick cooling method disclosed in the utility model are situated between using the water higher than flue gas thermal capacitance as cooling
Matter, a step realize cooling high-temperature fume, and 800 DEG C or so of radioactivity high-temperature flue gas is directly cooled to 75 DEG C of left sides by moment (in 1s)
The right side, not only cooling technique and device structure are simple, good cooling results, and can wash off the acidic materials in part of smoke,
To reduce corrosion of the flue gas to subsequent other processing equipments, prolong the service life, reduces operation investment.Furthermore in cyclic annular water pipe
On be intensively distributed with multiple pressure atomization spray heads, be not easy to plug, ensure that the safety and stabilization of cooling procedure.Meanwhile the present invention
Disclosed device and method can be used for the quenching of hazardous waste, medical wastes incineration high-temperature flue gas, and versatility is good.
