Abstract
The invention discloses a spray nozzle for coal dust, belonging to the technical field of coal dust combustion. The spray nozzle for coal dust comprises a screw, a sleeve and a wind pipe, the screw is arranged in the sleeve, the back part of the sleeve is provided with a coal dust inlet, the wind pipe is sheathed on the front part of the sleeve, the front port of the sleeve is sheathed in the front port of the wind pipe. The spray nozzle for coal dust has simple structure and small volume, thus being applicable to large-and-medium-sized pulverized coal burner; in addition, the coal dust burning method is also applicable to small-and-medium-sized boilers. The spray nozzle for coal dust can accurately control feeding amount of coal dust and wind inlet amount, achieving ideal air-fuel ratio by mixing the coal dust and the air, in addition, the atomization effect is good, the combustion efficiency of the coal dust is improved and pollutant discharge reduced. Meanwhile, the spray nozzle for coal dust operates reliably and is not prone to block.
Description
Technical field
The invention discloses a kind of breeze atomizing injector, belong to coal powder burning technology field.
Background technology
Coal dust firing is a kind of efficiency of combustion height, the method for the coal burning that disposal of pollutants is few.But because the equipment complexity that coal dust mixes with air is huge, coal dust combustion method can only be applied in the large-sized station boiler at present, limit the application of coal dust combustion method on medium and small boiler.
Summary of the invention
The objective of the invention is to invent a kind of breeze atomizing injector, coal dust is mixed with air, be suitable for being applied on the large, medium and small coal burner, make medium and small boiler also can use coal dust combustion method.
Breeze atomizing injector of the present invention is made up of screw rod, sleeve and airduct, and screw rod is installed in the sleeve, and the sleeve rear portion has the coal dust import, and duct sleeve is contained in the sleeve front portion, and the front port of sleeve is enclosed within the front port of airduct.
Described screw rod is made up of axostylus axostyle and helical spring, and helical spring is enclosed within on the axostylus axostyle, and helical spring rear end is fixed on the rear end of axostylus axostyle.
Described helical spring front end grows the front end of axostylus axostyle.
Described screw rod is a multiple-threaded screw.
The front end of described airduct has adjustable damper.
In the coal dust import of sleeve, the coal dust bucket is housed.
In described coal dust bucket, agitator is housed.
Blower fan is equipped with at air inlet place at airduct.
The designed breeze atomizing injector of the present invention has following advantage:
1. breeze atomizing injector is simple in structure, and volume is little, is suitable for using on large, medium and small coal burner, makes medium and small boiler also can use coal dust combustion method.
2. breeze atomizing injector can accurately be controlled the coal dust amount of feeding and intake, makes coal dust mix the air-fuel ratio that reaches desirable with air, and atomizing effect is good, improves the efficiency of combustion of coal dust, reduces disposal of pollutants.
3. breeze atomizing injector utilizes adjustable damper, can change the air-fuel ratio of coal dust fast, can form the higher igniting of coal powder density and burn normally with coal dust wind and coal powder density and use coal dust wind, can rekindle fast after making the combustion flame cutoff.
4. the coal dust amount of feeding, intake and the adjustable damper of breeze atomizing injector can realize control automatically, make breeze atomizing injector easy and simple to handle.
5. breeze atomizing injector reliable operation, when adopting the screw rod of helical spring type, since helical spring strain, the more difficult obstruction of coal dust.
Description of drawings

Fig. 2 is that the A of Fig. 1 is to view
Fig. 3 is the structural representation of second kind of breeze atomizing injector
The specific embodiment
The structural representation of the described breeze atomizing injector of present embodiment is seen Fig. 1, shown in Figure 2.
Breeze atomizing injector is made up of screw rod 1, sleeve 2 and airduct 3, and screw rod 1 is installed in the sleeve 2, and sleeve 2 rear portions have coal dust import 4, and airduct 3 is sleeved on sleeve 2 front portions, and the front port of sleeve 2 is enclosed within the front port of airduct 3.
During breeze atomizing injector work, rotated by motor drives screw rod 1, coal dust enters in the sleeve 2 from coal dust import 4, is pushed out sleeve 2 by screw rod 1; Air is delivered to the front port of sleeve 2 and the front port of airduct 3 from airduct 3, and air and coal dust mixed aerosol form coal dust wind and eject.
This breeze atomizing injector is simple in structure, and volume is little, is suitable for using on large, medium and small coal burner, makes medium and small boiler also can use coal dust combustion method.Regulate motor speed and intake, breeze atomizing injector can accurately be controlled coal dust and air admixture, reaches desirable air-fuel ratio, and atomizing effect is good, improves the efficiency of combustion of coal dust, reduces disposal of pollutants.
The structural representation of the described breeze atomizing injector of present embodiment is seen Fig. 3, shown in Figure 4.
The structure of the structure of the described breeze atomizing injector of present embodiment and embodiment 1 described breeze atomizing injector is basic identical.Difference is that described screw rod 1 is made up of axostylus axostyle 5 and helical spring 6, and helical spring 6 is enclosed within on the axostylus axostyle 5, and the rear end of helical spring 6 is fixed on the rear end of axostylus axostyle 5, and the front end of helical spring 6 grows the front end of axostylus axostyle 5.The front end of airduct 3 has adjustable damper 7 in addition.Coal dust bucket 8 is housed in coal dust import 4, agitator 9 is housed in the coal dust bucket 8.Blower fan 10 is equipped with at air inlet place at airduct 3.
The described breeze atomizing injector of present embodiment is except the advantage with embodiment 1 described breeze atomizing injector, also has following advantage, screw rod 1 is made up of axostylus axostyle 5 and helical spring 6, when screw rod 1 pushes coal dust, because helical spring 6 flexible distortion, can avoid the bulky grain coal dust to get stuck, make the more difficult obstruction of coal dust.Stretch out the helical spring 6 of the front end of axostylus axostyle 5 more, can help coal dust to disperse, improve the breeze atomizing effect.Close adjustable damper 7, reduce intake, change the air-fuel ratio of coal dust, can form the higher coal dust wind of coal powder density fast, igniting is used to restrike; Open adjustable damper 7, increase intake, can form the normal coal dust wind of coal powder density, be used for normal combustion.In coal dust import 4, load onto coal dust bucket 8 and agitator 9, and blower fan 10 is housed, can make breeze atomizing injector form independently breeze atomizing equipment, be convenient to practical application at the air inlet place of airduct 3.The screw rod 1 of breeze atomizing injector, adjustable damper 7 and blower fan 10 can be installed electric controller, automatically regulate the switching of the coal dust amount of feeding, intake and adjustable damper, realize the automatic control of the coal dust wind of variable concentrations, make breeze atomizing injector easy and simple to handle.
