Specific embodiment：
Embodiment 1：
A kind of device of the built-in First air pathogenic wind-warm improving urea pyrolysis, its composition includes：Pyrolysis oven, its feature
It is：Described pyrolysis oven 1 passes through to connect air channel 4 connection electric heater 2, and described electric heater passes through connection air channel and connects boiler
Cigarette wind heat-exchanging tube bundle 6 in back-end ductwork reversal chamber 7, described cigarette wind heat-exchanging tube bundle passes through to connect air channel connection volume damper
Group 8, described volume damper group passes through to connect air channel connection heat primary air system 9, and described pyrolysis oven is also by connection wind
Road connects urea liquid system 5 and spraying system 3.
Embodiment 2：
The device of the First air pathogenic wind-warm of built-in raising urea pyrolysis according to embodiment 1, described cigarette wind changes
Heat pipe bundle is located at boiler back end ductwork and turns to interior, and the outlet of cigarette wind heat-exchanging tube bundle is connected by being connected air channel with electric heater, electricity
Heater outlet is passed through connection air channel and is connected with pyrolysis oven, and volume damper group is arranged on the connection wind before cigarette wind heat-exchanging tube bundle
On road, described cigarette wind heat exchanger tube connects heat primary air air inlet system by volume damper group, described volume damper group
Intake can be adjusted.
Embodiment 3：
The method of work of the device of First air pathogenic wind-warm of built-in raising urea pyrolysis according to embodiment 2, heat
First air is entered by connecting the cigarette wind heat-exchanging tube bundle in air channel entrance boiler back end ductwork reversal chamber by heat primary air air inlet system
Row once heats, and is entering electric heater post bake by connecting air channel, electric heater, as temperature adjustment means, works as boiler
When cigarette wind heat-exchanging tube bundle in back-end ductwork reversal chamber be enough to be heated to heat primary air the temperature making urea pyrolysis needs, electricity adds
Hot device does not work, when the cigarette wind heat-exchanging tube bundle in boiler back end ductwork reversal chamber exert oneself can not meet require when, electric heater work
Make, post bake is carried out to heat primary air so as to pass through again after reaching the temperature of urea pyrolysis needs to connect air channel entrance pyrolysis
Stove participates in reaction.
