Description
Technical field
The utility model is related to denitration technology field, especially a kind of denitration device without catalyst.
Background technology
In the denitration scheme typically without catalysis, using by adding denitration in 800-1100 DEG C of flue gas treating process
Agent such as liquefied ammonia, ammonia or urea liquid reduce nitrogen oxides（NOx）Discharge capacity, the method to a certain extent can be by nitrogen oxidation
Thing（NOx）N2 is reduced into, but its denitration efficiency is general all very low, particularly with large-sized boiler.Main cause is that denitration efficiency is received
Following factor influence：1）Nitrogen oxides and denitrfying agent cannot sufficiently mix in combustion chamber；2）The cigarette in denitration reaction region
Temperature degree skewness；Therefore, many traditional SNCR methods can not meet and nowadays nitrogen oxides from coal-fired boiler has been arranged
Strict demand high-volume.
The content of the invention
The utility model is directed to deficiency of the prior art, there is provided a kind of denitration device, it can be sufficiently mixed nitrogen oxidation
Thing and denitrfying agent, while the denitration efficiency for avoiding the temperature inequality of conversion zone from causing is low.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of denitration device,
Including housing, the passage and the nozzle for spraying ammonia passed through for flue gas are provided with the housing, are located in the passage
Position above the nozzle is provided with the back-up ring of a ring shape, and one piece of spoiler, the spoiler are provided with the back-up ring
Including the fixed plate and T-shaped plate that are made of metal, the fixed plate is the back-up ring of a ring shape, and the T-shaped plate includes two pieces mutually
The metallic plate of perpendicular setting, the end of one of metallic plate is mutually welded with the centre position of another piece of metallic plate, described solid
On the back-up ring, the two ends of the T-shaped plate are fixed in the fixed plate fixed board frame.The plate being vertically arranged in T-shaped plate can be by
Air-flow is split, and then horizontally disposed plate can converge air-flow again, and the mixture of flue gas and ammonia in flue is by so anti-
After multiple segmentation converges, can sufficiently be well mixed, while the part of this spoiler is all made of metal, because golden
The good heat conductivity of category, can allow flue gas and ammonia by this it is local when, be heated evenly.Which greatly enhances denitration efficiency.
In above-mentioned technical proposal, it is preferred that slot, the insertion institute at the two ends of the T-shaped plate are provided with the fixed plate
State in slot.
In above-mentioned technical proposal, it is preferred that the T-shaped plate has two-layer, the spaced setting of T-shaped plate described in two-layer.
Compared with prior art, the beneficial effects of the utility model are：The plate being vertically arranged in T-shaped plate can be by air-flow point
Cut, then horizontally disposed plate can converge air-flow again, the mixture of flue gas and ammonia in flue by so repeatedly point
Cut after converging, can sufficiently be well mixed, while the part of this spoiler is all made of metal, because metal is led
Good in thermal property, can allow flue gas and ammonia by this it is local when, be heated evenly.Which greatly enhances denitration efficiency.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of spoiler.
Specific embodiment
The utility model is described in further detail with reference to specific embodiment and accompanying drawing.
As shown in Fig. 1 to 2, a kind of denitration device, including housing 1, it is provided with the passage passed through for flue gas in the housing 1
11 and for spraying the nozzle 2 of ammonia.
Position in the passage 11 positioned at the top of the nozzle 2 is provided with the back-up ring 12 of a ring shape, the back-up ring 12
On be provided with one piece of spoiler 3, the spoiler 3 includes the fixed plate 31 and T-shaped plate 32 that are made of metal, the fixed plate 31
Be the back-up ring of a ring shape, the T-shaped plate includes two pieces of metallic plates of orthogonal setting, the end of one of metallic plate with
Mutually weld in the centre position of another piece of metallic plate.The T-shaped plate has two-layer, the spaced setting of T-shaped plate described in two-layer.
The fixing frame plate is provided with slot, the insertion at the two ends of the T-shaped plate on the back-up ring in the fixed plate
In the slot.
The plate being vertically arranged in T-shaped plate can split air-flow, and then horizontally disposed plate can converge air-flow again, in flue
Flue gas and ammonia mixture after so segmentation repeatedly converges, can sufficiently be well mixed, while this disturb
The part for flowing plate is all made of metal because the good heat conductivity of metal, can allow flue gas and ammonia by this it is local when,
It is heated evenly.Which greatly enhances denitration efficiency.
