System is simpler, reduces the input of early stage, operation expense, and reduces the formation of nitrogen oxides, serves low nitrogen
The effect of burning.
The technical scheme in the invention for solving the technical problem is：
A kind of sludge handled for sludge drying mixes burning processing system, and it is defeated to include belt successively along the walking path of sludge
Mechanical, electrical dynamic belt tripper, sludge bin, conveying worm and breaking drying machine are sent, the sludge of the breaking drying machine enters
Mouthful and gas approach outlet respectively with the conveying worm and economizer after flue be connected, the breaking drying machine
Outlet be connected by air-introduced machine with boiler, on described boiler be located at burner top be along the circumferential direction uniformly arranged it is some
Certain distance N is respectively provided between individual sludge inlet, and the axis of the center line of several sludge inlets and the boiler, and in stove
The first vortex inscribed circle is formd in thorax.
Further, the quantity of the burner is several, and is along the circumferential direction uniformly arranged, and several burners
Center line and the boiler between be respectively provided with a certain distance M, and in freeze profile into second eddy current inscribed circle.
Further, the first vortex inscribe diameter of a circle is equal with the second eddy current inscribe diameter of a circle.
Further, the quantity of the burner is equal with the quantity of the sludge inlet, and arranged for interval；
Further, it is provided with air-flow intensifying device between described breaking drying machine and air-introduced machine.
The beneficial effects of the utility model are：
1st, because the utility model directly will be sent to stove by the sludge of breaking drying machine by the attraction of air-introduced machine
Carry out mixing burning in thorax, therefore with regard to equipment itself, the cyclone separator for separating gas and sludge is eliminated, for storing
The storage warehouse of dewatered sludge, and for distributing the storehouse pump or dewatered sludge distribution conveyor of conveying dewatered sludge, make system simpler,
Operation expense is low.
2nd, dried sludge water content reduction, volatile content is higher, and burner hearth, energy are passed through from existing hearth combustor top
The precipitation fugitive constituent of enough rapid, high volumes, makes locally to produce reproducibility environment in burner hearth, so when being passed into the coal dust in burner
The nitrogen oxides produced after burning, by the effect of the reducibility gas in reproducibility environment, is reduced during rising
Into nitrogen, so as to reduce the formation of nitrogen oxides, the effect of low nitrogen burning is served.
3rd, by setting several sludge inlets on the furnace wall of boiler, and several sludge inlets center line and institute
State perpendicular where axis of boiler at an angle, and in freeze profile into vortex inscribed circle (described vortex inscribed circle
For an imaginary circle), eddy current effect is formed, to ensure fully burning.

Embodiment
Embodiment one
As shown in figure 1, a kind of sludge handled for sludge drying, which mixes burning processing system, includes sludge bin 3, the sludge
The top in storehouse 3, which is provided with the belt conveyor 1 for transporting sludge, described belt conveyor 1, is located at described sludge bin 3
Top be provided with electric belt discharger 2.The lower end of the sludge bin 3 passes through conveying worm 4 and breaking drying machine 5
Sludge import is connected, and the gas approach of the breaking drying machine 5 is connected by pipeline with economizer rear pass, for receiving to come
From the heat smoke of economizer.The outlet of the breaking drying machine 5 is connected by air-introduced machine 6 with boiler 7.
Further, it is provided with air-flow in order to increase current rate, between described breaking drying machine and air-introduced machine strong
Makeup is put, and described air-flow intensifying device is prior art, be will not be repeated here.Air-flow reinforcing dress employed in the present embodiment
The model GQS750 put.
As shown in Figures 2 and 3, several burners 71 have along the circumferential direction been uniformly arranged on described boiler 7, and it is some
It is respectively provided with a certain distance M between the center line of individual burner and the boiler, and in freeze profile into second eddy current inscribe
Circle (described second eddy current inscribed circle is an imaginary circle).Form eddy current effect, the abundant burning of coal dust.On described boiler 7
Several sludge inlets 72 have along the circumferential direction been uniformly arranged positioned at the top of the burner 71, and several sludge inlets
Certain distance N is respectively provided between the axis of center line and the boiler, and it is (described into the first vortex inscribed circle in freeze profile
First vortex inscribed circle be an imaginary circle).Vortex is formed corresponding, to ensure the abundant burning of sludge.It is preferred that, described first
It is vortexed inscribe diameter of a circle equal with the second eddy current inscribe diameter of a circle, i.e. M is equal to N, and coaxial distribution.
It is preferred that, the quantity of the burner 71 is equal with the quantity of the sludge inlet 72, and arranged for interval.
As a kind of embodiment, in the present embodiment, the boiler 7 is the coal-powder boiler being square, the burner
71 quantity is four, and the burner 71 described in four is respectively arranged on four angles of the boiler 7, the sludge inlet
72 quantity is four, and the sludge inlet 72 described in four is respectively arranged on four sidewall panelings of the boiler 7.
During work, sludge is put into sludge bin 3 by belt conveyor 1 and electric belt discharger 2 first, then sludge
Sludge is transported in breaking drying machine 5 by the sludge in storehouse 3 by conveying worm 4, at the same time, the cigarette after economizer
The heat smoke in road is entered in breaking drying machine 5 also by pipeline, and sludge is dried in breaking drying machine 5.
By dry sludge, entered in boiler 7, burnt in burner hearth by sludge inlet 72 in the presence of air-introduced machine 6.
Because dried sludge water content is substantially reduced, volatile content is higher, therefore can be quick during burning
The substantial amounts of fugitive constituent of precipitation, make the reproducibility environment for forming a part in burner hearth positioned at the top of burner 71, such coal
Powder is entered in boiler 7 from burner 71, and is burnt in boiler 7, and nitrogen oxides can be undoubtedly produced during burning, is produced
Raw nitrogen oxides during rising by top reproducibility environment, in the presence of reducibility gas, a part of nitrogen
Oxide is reduced into nitrogen, so as to reduce the formation of nitrogen oxides, serves the effect of low nitrogen burning.
In addition, being existing by drying sludge, then by drying because traditional sludge mixes firing technique as shown in Figure 5 and Figure 6
Sludge and coal dust afterwards is mixed, and is then passed into sludge in boiler 7 together with the mixture of coal dust.So on the one hand need
Storage and the distributing equipment of dewatered sludge are wanted, system complex, cost is high；On the other hand, due to sludge after coal dust and sludge mixing
Content is less, and the fugitive constituent concentration separated out after being passed into boiler 7 is low, it is impossible to locally producing reproducibility environment, it is impossible to rise
To the effect of low nitrogen burning.
