Description
Technical field
The utility model relates to a kind of combustion system, particularly a kind ofly take the burning dust pelletizing system that plant powder is fuel.
Background technology
At present, all there is energy crisis in All Around The World, and the subterranean resource such as coal, oil face exhaustion, and the price of coal and oil skyrockets.And the pesticide forest product leftover wide material sources such as various sawdusts, stalk, plant shell, but they are by a large amount of abandonments, are sometimes taken as incineration firing to fall, and have not only wasted resource, and polluted environment.
Prior art mostly is its pulverizing is become to plant powder the utilization of the pesticide forest product leftovers such as sawdust, stalk, plant shell, usings this as fuel.But all can produce a large amount of dust in pesticide forest product leftover crushing process and in plant powder combustion process, pollute obviously, affect the healthy of staff, cannot the requirement of satisfy regulatory to environmental protection, and use plant powder for fuel is to existing steam generator system inapplicable.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of plant powder burning dust pelletizing system is provided, and can make full use of plant powder, and effectively dedusting again, reduces the pollution to environment, can make full use of existing steam generator system again.
The purpose of this utility model is achieved in that this plant powder burning dust pelletizing system comprises feeding mechanism, combustor, dedusting mechanism, described feeding mechanism connects described combustor, described combustor connects described combustion furnace, and described feeding mechanism and described combustion furnace arrange respectively dedusting passage to described dedusting mechanism.
Described feeding mechanism comprises storing room, feed bin, and described storing room arranges feeding device to described feed bin, and described feed bin setting is connected to the feeding device of described combustor.
The fuel inlet of described combustion furnace connects the crater of described combustor, and described combustion furnace can be oil burner, gas furnace or coal furnace.
Described dedusting mechanism comprises cyclone separator and sack cleaner, and the other end that connects the dedusting passage of described feeding mechanism is connected between described cyclone separator and described sack cleaner.
Between described combustion furnace and described dedusting mechanism, cooling body is set, from described combustion furnace flue gas out, enters described dedusting mechanism first cooling through described cooling body before.
Described dust pelletizing system is provided with suspended hood at described storing room and the described feed bin of described feeding mechanism.
Described combustor is provided with self-con-tained unit, and described self-con-tained unit is by the work of combustor described in the Steam pressure control of the boiler that heated by described combustion furnace.
The beneficial effects of the utility model: plant powder burning dust pelletizing system can utilize existing steam generator system to transform, the combustion furnaces such as original coal furnace, oil burner or gas furnace are all without replacing, can be widely used various plant powders, applied widely, and plant powder belongs to renewable resource, environmental protection again with low cost.Owing to each may being produced to the link of pollution, carried out dedusting, thereby eliminated dust pollution, discharge can meet the requirement of government regulation to environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Principle of the present utility model is: plant powder enters combustor by feeding mechanism, and after combustor burning, the pyrotechnics of gained enters combustion furnace and further burns, and heating boiler is to produce steam.The flue gas that combustion furnace is discharged enters atmosphere after dedusting mechanism dedusting.The dust that dedusting mechanism also produces feeding mechanism carries out dedusting.
Below in conjunction with accompanying drawing, the utility model is described in detail as follows.
As shown in Figure 1, feeding mechanism comprises storing room 1, feed bin 12, and storing room arranges feeding device 11 to feed bin, and feed bin setting is connected to the feeding device 13 of combustor 4.The agriculture and forestry products such as sawdust, stalk, plant shell are ground into plant powder, enter storing room and store.When system needs, feeding device is delivered to feed bin by plant powder, then by the feeding device of feed bin bottom, plant powder is sent in combustor and burnt.The combustion furnaces such as original coal furnace, oil burner or gas furnace are also not suitable for directly burning plant powder, and plant powder combustor is also not suitable for directly boiler being heated to produce steam.Thereby install plant powder combustor additional at existing steam generator system, the pyrotechnics that plant powder produces after combustor burning enters combustion furnace by the crater 41 of combustor and the fuel inlet 31 of combustion furnace 3 and further burns, water in boiler is heated and produces steam, and steam is broad-spectrum thermal source, so far reached plant powder as the effect of fuel.
Dedusting mechanism comprises cyclone separator 24 and sack cleaner 27, and combustion furnace is connected to cyclone dust collectors through airduct 23, and cyclone dust collectors are connected to sack cleaner through airduct 25.Blower fan 28 is set on sack cleaner discharges the gas after dedusting.
The dusty gas that feeding mechanism produces is connected to the airduct 25 between cyclone dust collectors and sack cleaner through airduct 26.Airduct 26 is not attached to one of reason of airduct 23, be that combustion furnace flue-gas temperature is out higher, even may contain flame, and the dust that airduct 26 is come contain plant powder, may cause wood powder to burn within cyclone dust collectors, equipment is produced to harmful effect; Former therefore two, be that cyclone dust collectors do not need work when combustion furnace is not discharged fume, now only start sack cleaner and can carry out dedusting to feeding mechanism.
Because combustion furnace flue-gas temperature is out higher, even may contain flame, likely sack cleaner be produced and destroyed, thereby where necessary, can cooling body be set before sack cleaner, make to enter sack cleaner from combustion furnace flue gas out and obtain before cooling.This sack cleaner can be arranged between combustion furnace and cyclone dust collectors, also can be arranged between cyclone dust collectors and sack cleaner.
Blower fan 22 is set on airduct 26, and is connected to the suspended hood 21 that is arranged at feed bin, airduct 20 connects suspended hood 21 and storing room.In storing room, can also produce after dust part arranges suspended hood and come together in airduct 20 at each.
At existing combustion furnace, steam generator system, the burning of combustion furnace is controlled by self-con-tained unit by the steam pressure of boiler.In the utility model, the burning that need to control plant powder just can reach the object of fuel saving, thereby the control object of self-con-tained unit is combustor.When steam pressure raises to arrive, shut down setting value, self-con-tained unit control combustion machine makes it to stop burning, and feeding device stops discharging, fuel saving.When steam pressure reduces, reach start setting value, self-con-tained unit control combustion machine makes it burning, feeding device discharging.
