Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, right below by drawings and examples
Technical solution of the present invention is described in further detail.It should be understood that specific embodiment described herein is only used
In explaining the principle of the present invention, it is not intended to limit the present invention.
As shown in Figure 1, a kind of waste gas burning processing equipment provided by the invention, includes: combustion chamber, gas inlet pipeline,
Discharge tube, igniter and gas pipeline.Wherein, combustion chamber specifically includes concatenated upstream combustion chamber and downstream combustion chamber.
Referring to Fig. 1, upstream combustion chamber includes fire ring 11 and wind scooper 13, and fire ring one end connects gas pipeline 15, separately
One end connects igniter 17, connects gas inlet pipeline 19 in the middle part of fire ring.After 17 ignition ring 11 of igniter, combustion gas
Oxygen in natural gas and air in pipeline 15 combines, and full combustion heats the heat-accumulation combustion room in downstream.Fire ring
The wind scooper 13 of 11 upper ends is formed after the exhaust gas that gas inlet pipeline 19 generates injects wind scooper in up-small and down-big horn-like
Negative pressure, conducive to the lower mouth of wind scooper 13 air enter in wind scooper participate in it is combustion-supporting.
In order to facilitate the control of natural gas, it is additionally provided with solenoid valve on above-mentioned gas pipeline 15, even if combustion can be opened or closed
Feed channel 15.It is additionally provided with flame detector in igniter 17, fire ring is not lighted a fire or flame light intensity does not meet and wants when detecting
When asking and alarm.It should be noted that downstream combustion chamber is also since the exhaust gas after the rigid blow-on of nitriding furnace is not easy to be ignited
Exhaust gas itself can be preheated, so that exhaust gas is easier to be ignited when entering downstream combustion chamber or heat resolve.
Downstream combustion chamber uses heat-accumulation combustion room, receives the heating of above-mentioned upstream combustion chamber, includes shell 21 and heat preservation
Layer 23.Shell 21 is the steel plate cylinder formed using heat-resisting steel sheet and plate, specifically, it uses upper and lower heat-resisting steel sheet and plate to be welded.It protects
Warm layer 23 is designed to the labyrinth type building of multilayer, is conducive to ammonia stay longer on the insulating layer, so that ammonia more fills
The decomposition divided.Specifically, every layer of insulating layer uses heat-resistant insulation material, such as built using alumina-silicate ceramic fibre felt.It needs to refer to
Out, above-mentioned insulating layer is not limited in labyrinth type tier building, other multilayered structures can also be used, as alternate intervals are set
The ladder-like insulating layer set.
Specifically, the above-mentioned waste gas burning processing equipment course of work is as follows: opening solenoid valve, be passed through toward upstream combustion chamber
Imflammable gas (such as natural gas), while being passed through natural gas and exhaust gas to upstream combustion chamber, igniter is to burning circling point
Fire；Exhaust gas is preheated while combustion of natural gas heated downstream heat-accumulation combustion room；The exhaust gas of preheating enters heat-accumulation combustion room,
It at a high temperature of labyrinth type insulating layer, is sufficiently decomposed and is burnt, heat-accumulation combustion room is discharged in the gas after final combustion.It needs
It is emphasized that such as 30 minutes, downstream heat-accumulation combustion room reached when upstream combustion chamber heats one section to downstream heat-accumulation combustion room
To preset temperature (such as 900 degree, ammonia can be decomposed sufficiently at 900 degree or so), can stop providing natural gas, thus energy saving.
For above-mentioned waste gas burning processing equipment, the present invention is also corresponding to provide the waste gas processing method of the equipment, specific packet
