The beneficial effects of the utility model are: novel tail-gas combustion stove, reached that exhaust combustion is complete, efficient is high, steam production is large, security of operation, be easy to clean and do not need the technological transformation purpose that the special messenger keeps an eye on, and has obtained success, for enterprise has created good economic benefit.
Description of drawings
Accompanying drawing 1 is the structural representation of tail-gas combustion stove of the present utility model.
Label declaration: 1-surge chamber; The 11-offgas duct; The 12-evacuated tube; The 13-air inlet pipe; 2-combustion furnace body; The 21-combustion chamber; The 22-vaporium; The 23-blast pipe; The 24-water inlet pipe; The 25-steam pipe; The 3-exhaust-valve; The 4-intake valve; The 5-breather valve.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, below in conjunction with embodiment and cooperate that accompanying drawing is detailed to give explanation.
See also Fig. 1, a kind of tail-gas combustion stove that the utility model provides shown in the accompanying drawing, comprise surge chamber 1 and combustion furnace body 2, described combustion furnace body 2 is followed successively by combustion chamber 21 and vaporium 22 from bottom to top, the top of described combustion furnace body 2 is provided with blast pipe 23, be provided with the water inlet pipe 24 and the steam pipe 25 that connect vaporium 22 on the described combustion furnace body 2, be provided with offgas duct 11 on the described surge chamber 1, evacuated tube 12, air inlet pipe 13, be provided with exhaust-valve 3 on the described evacuated tube 12, described air inlet pipe 13 stretches in the described combustion chamber 21, be provided with intake valve 4 on the described air inlet pipe 13, be provided with breather valve 5 on the described combustion chamber 21, be provided with the gripper shoe that fixedly secures two pipe positions between described offgas duct 11 and the evacuated tube 12.
During use, tail gas after the Formaldehyde Production passes into surge chamber 1 by offgas duct 11, close slowly first afterwards exhaust-valve 3, open slowly simultaneously intake valve 4, tail gas flows into combustion furnace body 2 along air inlet pipe 13, at this moment open the breather valve 5 on the combustion furnace body 2, air flows into combustion furnace body 2 by breather valve 5, tail gas is with after air fully mixes, in the explosion limit scope that guarantees tail gas safe, light a fire, usually the aerial explosion limit of formaldehyde is 6.2%-73.4%, and the rear whole mist of igniting is 21 internal combustion in the combustion chamber, and temperature is 400-600 ℃, at this moment the heat that produces heats vaporium 22, the water that water inlet pipe 24 passes into outwards provides heat energy from steam pipe 25 after becoming steam through thermal conversion, after tail gas is up to standard through burning, discharges from blast pipe 23.
