In view of above-described embodiment and accompanying drawing, structure and principle to the present invention are described further.
SNCR technology uses and sprays into certain density ammonia or carbamide in the inside of burner hearth 18, within burner hearth 18
Nitrogen oxides or sulfide that fuel produces reduce, thus reduce the discharge of nitrogen oxides or sulfide.But SNCR is only
Only use ammonia or carbamide etc. reducing agent nitrogen oxides or sulfide are processed, and SNCR technology to reaction temperature,
Concentration ranges etc. have certain requirement.
In general, nitrogen oxides NOXTypically anti-in the range of 850 DEG C～1100 DEG C with the reaction temperature of ammonia or carbamide
Should be optimal, and this temperature range is generally arranged above in the of 1, between face arch 2 and rear arch 3 at the chain of burner hearth 18.So the present invention passes through
Smoke eliminator is arranged on this and sentences realization to nitrogen oxides NOXAnd the integrated synthesis of sulfide processes, accelerate ammonia
Or the extent of reaction of carbamide and above-mentioned substance, increase the burning degree of flue gas itself, the raising utilization rate of oxygen own.
Saying further, the flue gas processing device in the present invention uses air disturbance and the principle of convection current, by flue gas not
Realizing being sufficiently mixed of flue gas with the difference of flow velocity, the existence of smoke convection and flow-disturbing phenomenon also is able to increase gas cleaning dress
Put the pressure of inside, promote second-time burning and the secondary response of flue gas, promote the abundant burning of fuel, promote ammonia or carbamide etc.
Reducing agent and nitrogen oxides NOXAnd the extent of reaction of sulfide.
For realizing above-mentioned principle, the present invention is by arranging above in the of 1 at the chain of burner hearth 18, be provided with one between face arch 2 and rear arch 3
Individual or the pipeline 14 of multiple arrangement, uses refractory material 21 envelope between adjacent channel 14 and between pipeline 14 and face arch 2, rear arch 3
Stifled, the flue gas so making the row of the chain below burner hearth 18 1 burning produce all enters into the top of burner hearth 18 by pipeline 14, and by
Within this enters into Heat Room 10.
When flue gas enters in pipeline 14, owing to the longitudinal section of pipeline 14 at least includes an internal diameter section of reducing 17, interior
An at least porch 19 being positioned at pipeline 14, the position of the footpath section of reducing 17, so, when flue gas is entered by narrower porch 19
When entering the pipeline 14 to wider bore footpath, owing to the change of cross-sectional diameter causes flue gas flow rate to change, the change of flue gas flow rate
Change can cause expansionary effect, and this expansionary effect one is to increase the air pressure within pipeline 14, two be can produce flue gas convection current and
Flow-disturbing phenomenon, also can promote the mixed of each material such as ammonia or carbamide, nitrogen oxides, sulfide etc. while promoting smoke combustion
Close, promote reaction.
The preferred plan of the present invention be at entrance 19 arrange before the internal diameter section of reducing 6, in the stage casing of pipeline 14 and lean on
On the position of nearly porch 19, the middle internal diameter section of reducing 7 is set, to the premenstrual internal diameter section of reducing 6 under the effect of the middle internal diameter section of reducing 7
The flue gas entered produces a choked flow effect, produces obvious smoke convection, the effect of flow-disturbing, is both and too increases at this
Flue gas pressures in segment pipe.Above-mentioned phenomenon makes flue gas produce more between the middle internal diameter section of reducing 7 and the front internal diameter section of reducing 6
Significantly second-time burning, the phenomenon of secondary mixing, thus promote that oxygen participates in burning and the degree of reduction reaction.
Enter in follow-up pipeline 14 through above-mentioned reacted flue gas via the middle internal diameter section of reducing 7, going out of pipeline 14
At Kou, 20 are positioned at the top of burner hearth 18, and in pipeline 14, flue gas out carries out heat exchange in entering into Heat Room 10.Through heat exchange
The flue gas of room 10 can by the spray effect of desulfurizing tower realize produce sulfuric acid by-products, flue gas can not only be processed and
And certain additional output value can also be realized.
In the present invention, being provided with cooling layer in the tube wall 15 of pipeline 14, this cooling layer can be water-cooled layer or air-cooled layer, water-cooled
Layer can use external water circle device, it is also possible to is realized by the water circle device of chain row's boiler internal.Air-cooled layer can lead to
Cross the supply air system of boiler internal or external supply air system to realize refrigerating function.Those skilled in the art can be by upper
State structure and design rational circulating path and device according to prior art, this is not made further details of theory by the present invention
Bright.
The invention provides a kind of concrete water-cooled layer structure, i.e. realize structure by some water cooling tubes 12 and connecting plate 13
Become the tube wall 15 of pipeline 14.The cross section of tube wall 15 is circular, as shown in Figure 4.Water cooling tube 12 by distributor pipe 5 respectively with collection
Case pipe 8, down-comer 4 are connected with upper drum 9, lower drum 11, thus by chain row boiler internal water circulation system realize right
The cooling of tube wall 15, utilizes the temperature difference between the high-temperature particulate matter of tube wall 15 and burning generation to avoid high-temperature particulate matter
Deposition at the internal diameter section of reducing 17, causes the blocking of pipeline 14.State the water-cooled under the function of cooling, in the present invention in realization
Pipe 12 can also play the effect of heat exchange, increases the heat transfer effect of boiler itself, promotes the original heat utilization rate of boiler.
Above-mentioned version, it is possible to make original chain row boiler during upgrading, by the chain at burner hearth
Smoke eliminator of the present invention is increased, it is possible to realize nitrogen oxides, the row up to standard of sulfide in chain row's boiler above row
Put, eliminate the black smoke phenomenon produced because combustion material is different and oxygen utilization is insufficient, reduce First air, secondary air system
Wind supply quantity, it is possible to reduce the usage amount of steel in newly constructed boiler and ensure the stability of boiler operatiopn, safe and reliable.
