In view of above-described embodiment and accompanying drawing, structure of the present utility model and principle 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 this utility model
Realization is sentenced to nitrogen oxides NO by smoke eliminator being arranged on thisXAnd the integrated synthesis of sulfide processes, accelerate
Ammonia or carbamide and the extent of reaction of 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 this utility model uses air disturbance and the principle of convection current, passes through cigarette
The difference of gas different in flow rate realizes being sufficiently mixed of flue gas, and it is clean that the existence of smoke convection and flow-disturbing phenomenon also is able to increase flue gas
Pressure within gasifying device, promotes second-time burning and the secondary response of flue gas, promotes the abundant burning of fuel, promotes ammonia or urine
The reducing agents such as element and nitrogen oxides NOXAnd the extent of reaction of sulfide.
For realizing above-mentioned principle, this utility model is by arranging above in the of 1 at the chain of burner hearth 18, set between face arch 2 and rear arch 3
There is the pipeline 14 of one or more arrangement, between adjacent channel 14 and between pipeline 14 and face arch 2, rear arch 3, use refractory material
21 closure, 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 within thereby 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.
Preferred plan of the present utility model be at entrance 19 arrange before the internal diameter section of reducing 6, in the stage casing of pipeline 14
And the middle internal diameter section of reducing 7 is set on the position of porch 19, under the effect of the middle internal diameter section of reducing 7, premenstrual internal diameter is reduced
The flue gases that section 6 enters produce choked flow effects, produce obvious smoke convection, the effect of flow-disturbing, are both and too increase
Flue gas pressures in this segment pipe.Above-mentioned phenomenon makes flue gas produce between the middle internal diameter section of reducing 7 and the front internal diameter section of reducing 6
The second-time burning that becomes apparent from, 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 this utility model, 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
Refrigerating function can be realized by the supply air system of boiler internal or external supply air system.Those skilled in the art can be led to
Cross said structure and design rational circulating path and device according to prior art, this is not made the most in detail by this utility model
Thin explanation.
This utility model provides a kind of concrete water-cooled layer structure, i.e. real by some water cooling tubes 12 and connecting plate 13
Now constitute 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 is by distributor pipe 5 respectively
It is connected with upper drum 9, lower drum 11 with collecting box pipe 8, down-comer 4, thus comes real by the water circulation system of chain row's boiler internal
The now cooling to tube wall 15, utilizes the temperature difference between the high-temperature particulate matter of tube wall 15 and burning generation to avoid high-temperature
Grain thing deposition at the internal diameter section of reducing 17, causes the blocking of pipeline 14.State under the function of cooling in realization, this utility model
In water cooling tube 12 can also play the effect of heat exchange, increase the heat transfer effect of boiler itself, promote the original heat energy of boiler sharp
By rate.
Above-mentioned version, it is possible to make original chain row boiler during upgrading, by the chain at burner hearth
Smoke eliminator described in the utility model is increased, it is possible to realize nitrogen oxides, the reaching of sulfide in chain row's boiler above row
Mark discharge, eliminates the black smoke phenomenon produced because combustion material is different and oxygen utilization is insufficient, reduces First air, secondary wind system
The wind supply quantity of system, it is possible to reduce the usage amount of steel in newly constructed boiler and ensure the stability of boiler operatiopn, safe and reliable.
