In view of above-described embodiment and attached drawing, are described further the structure and principle of the present invention.
SNCR technologies spray into certain density ammonium hydroxide or urea using in the inside of burner hearth 18, inside burner hearth 18
The nitrogen oxides or sulfide that fuel generates are restored, so as to reduce the discharge of nitrogen oxides or sulfide.But SNCR is only
Nitrogen oxides or sulfide are handled using only the reducing agent of ammonium hydroxide or urea etc., and SNCR technologies to reaction temperature,
Concentration range etc. has certain requirement.
In general, nitrogen oxides NOXIt is anti-generally in the range of 850 DEG C~1100 DEG C with the reaction temperature of ammonium hydroxide or urea
Should be best, and this temperature range is usually between the top of the chain of burner hearth 18 row 1, face arch 2 and rear arch 3.So the present invention passes through
By smoke eliminator installation here with realization to nitrogen oxides NOXAnd the integrated synthesis processing of sulfide, accelerate ammonium hydroxide
Or the extent of reaction of urea and above-mentioned substance, increase the burning degree of flue gas in itself, improve oxygen utilization rate itself.
Further speaking, the flue gas processing device in the present invention uses air disturbance and the principle of convection current, by flue gas not
Being sufficiently mixed for flue gas is realized with the difference of flow velocity, and the presence of smoke convection and flow-disturbing phenomenon can also increase gas cleaning dress
Internal pressure is put, promotes second-time burning and the secondary response of flue gas, promotes the abundant burning of fuel, promotes ammonium hydroxide or urea etc.
Reducing agent and nitrogen oxides NOXAnd the extent of reaction of sulfide.
To realize above-mentioned principle, the present invention between the top of the chain of burner hearth 18 row 1, face arch 2 and rear arch 3 by being equipped with one
The pipeline 14 of a or multiple arrangements uses 21 envelope of refractory material between adjacent channel 14 and between pipeline 14 and face arch 2, rear arch 3
It is stifled, so that the flue gas that 1 burning of chain row of 18 lower section of burner hearth generates enters the top of burner hearth 18 by pipeline 14, and by
This is entered within Heat Room 10.
When flue gas is entered in pipeline 14, section 17 is reduced since the longitudinal section of pipeline 14 includes at least an internal diameter, it is interior
Diameter reduce section 17 position at least one be located at the inlet 19 of pipeline 14, in this way, when flue gas by relatively narrow inlet 19 into
When entering to the pipeline 14 of wider bore diameter, since the variation of cross-sectional diameter causes flue gas flow rate to change, the change of flue gas flow rate
Change can cause expansionary effect, which is the air pressure that can increase inside pipeline 14, second is that can generate flue gas convection current and
Flow-disturbing phenomenon promotes also promote the mixed of each substance such as ammonium hydroxide or urea, nitrogen oxides, sulfide etc. while smoke combustion
It closes, promotes reaction.
The preferred plan of the present invention be at the entrance 19 set before internal diameter reduce section 6, in the stage casing of pipeline 14 and lean on
Internal diameter reduces section 7 in being set on the position of nearly inlet 19, reduces section 6 to premenstrual internal diameter under the action of middle internal diameter reduces section 7
The flue gas of entrance generates a choked flow effect, generates the effect of obvious smoke convection, flow-disturbing, is both to also increase at this
Flue gas pressures in segment pipe.Above-mentioned phenomenon causes flue gas to be generated more between middle internal diameter reduces section 7 and preceding internal diameter reduces section 6
The phenomenon that apparent second-time burning, secondary mixing, so as to which oxygen be promoted to participate in the degree of burning and reduction reaction.
Flue gas after above-mentioned reaction reduces section 7 via middle internal diameter and enters in subsequent pipeline 14, and pipeline 14 goes out
20 positioned at the top of burner hearth 18 at mouthful, enters in Heat Room 10 and exchanges heat from the interior flue gas out of pipeline 14.By heat exchange
The flue gas of room 10 can be acted on by the spray of desulfurizing tower and realize generation sulfuric acid by-products, flue gas can not only be handled and
And it also is able to realize certain additional output value.
In the present invention, it is equipped with cooling layer in the tube wall 15 of pipeline 14, which can be water-cooled layer or air-cooled layer, water cooling
External water circle device can be used in layer, can also arrange the water circle device of boiler internal by chain to realize.Air-cooled layer can lead to
The supply air system or external supply air system for crossing boiler internal realize refrigerating function.Those skilled in the art can be by upper
It states structure and designs rational circulating path and device according to the prior art, make further details of theory not to this in the present invention
It is bright.
The present invention provides a kind of specific water-cooled layer structures, i.e., realize structure by several water cooling tubes 12 and connecting plate 13
Into the tube wall 15 of pipeline 14.The cross section of tube wall 15 is circle, as shown in Figure 4.Water cooling tube 12 by distributor pipe 5 respectively with collection
Case pipe 8, down-comer 4 are connect with upper drum 9, lower drum 11, are realized pair so as to arrange the water circulation system of boiler internal by chain
The cooling of tube wall 15 avoids high-temperature particulate matter using the temperature difference between tube wall 15 and the high-temperature particulate matter of burning generation
The deposition at section 17 is reduced in internal diameter, causes the blocking of pipeline 14.Under the function of stating cooling in realization, the water cooling in the present invention
Pipe 12 also is able to play the role of heat exchange, increases the heat transfer effect of boiler in itself, promotes the original heat utilization rate of boiler.
Above-mentioned structure type enables to original chain to arrange boiler during upgrading, passes through the chain in burner hearth
Row top increases smoke eliminator of the present invention, can realize the row up to standard of nitrogen oxides, sulfide in chain row's boiler
It puts, eliminates the black smoke phenomenon generated due to combustion material is different and oxygen utilization is insufficient, reduce First air, secondary air system
Volume of air supply can reduce the usage amount of steel in newly constructed boiler and ensure the stability of boiler operatiopn, securely and reliably.
