Specific embodiment
The utility model is further described below in conjunction with accompanying drawing：
As shown in figure 1, the technical scheme that the utility model is taken is as follows：
The equipment that a kind of use spray drying technology treatment uranyl nitrtate is pyrolyzed denitration, including air accumulator 1, combustor 2, combustion
Gas and hot air stove 3, pressure fan 4, main tower 5, hot-air distributor 6, pressure nozzle atomizers 7, feeding engine 8, heating wire 9, storage tank
10th, cooling system 11, cyclone separator 13, sack cleaner 14, exhaust treatment system 15, air-introduced machine 16；The main tower 5 is pushed up
Portion inner side is provided with hot-air distributor 6, and pressure nozzle atomizers 7 are installed on the inside top of main tower 5 simultaneously, and its lower end passes through heat
Wind distributor 6；The feeding engine 8 is connected with pressure nozzle atomizers 7, storage tank 10 respectively, the outer surface of storage tank 10 parcel peace
Equipped with heating wire 9；The bottom sandwiching surface of the main tower 5 is provided with cooling system 11, and the bottom of main tower 5 is connected with pipeline, pipe
The road other end is connected with cyclone separator 13, and sack cleaner 14 is connected by pipeline with cyclone separator 13, vent gas treatment system
System 15 is connected by pipeline with sack cleaner 14, and air-introduced machine 16 is connected by pipeline with exhaust treatment system 15；The combustion gas
Hot-blast stove 3 is connected by pipeline with hot-air distributor 6, and pressure fan 4, combustor 2 are provided with the outer wall of fuel gas hot-blast stove 3, described
Air accumulator 1 is connected by pipeline with combustor 2.
After heating wire 9 is powered, feed liquid is heated to more than 70 DEG C in storage tank 10 by heating wire 9, is delivered to by feeding engine 8
In the pressure nozzle atomizers 7 at the top of main tower 5, it is droplet group that feed liquid is equably atomized, into main tower 5；
During normal temperature air enters fuel gas hot-blast stove 3 in the presence of pressure fan 4, with the combustion in the burning air accumulator 1 of combustor 3
Material（Fuel is propane, liquefied gas, natural gas etc.）Produced hot-air is sufficiently mixed, and is heated to drying denitration needs 600
DEG C -800 DEG C of temperature, by hot-air distributor 6 around pressure nozzle atomizers surrounding hot-blast outlet, Direct Uniform sprays into king-tower
