Description
Technical field
The utility model relates to the biomass boiler technical field, specifically a kind of recirculating fluidized bed biomass boiler with runner ash discharging gear.
Background technology
Recirculating fluidized bed biomass boiler slag ash content is few, in light weight.Before boiler tail, the flue cyclone is set at present.The ash discharge mode has manually or the automatic ash discharge of machine.
Manually ash discharge is exactly regularly to open release dry ash or water spray of dust arrester bottom gate ash content is flushed to the sedimentation basin deposition.The former regularly opens burner hearth, and cold air gets into burner hearth, influences boiler combustion efficiency; When starting gate was let out ash, a large amount of ash contents got into flue, increase the load pressure of postorder cleaner, ash content escape meeting atmosphere pollution; Detonation takes place in biomass fuel complicated component, calorific value instability easily, opens the sluices, and boiler furnace is in open state, and during detonation, just from the sluice gate ejection, security is not enough for a large amount of hot gas.Latter's airtight condition is good slightly, but polluted-water increases environmental protection pressure.The biomass boiler lime-ash is good crops fertilizer, after the water flushing, and the useful component forfeiture, value reduces.
The automatic ash discharge of machine generally adopts screw ash-discharging device, screw ash-discharging device at ash content after a little while, obturation effect is not good, when running into the bulk object, easy blocking.
The utility model content
Not good, the easy obstruction and secondary pollution problem of airtight condition that the utility model brings for solving traditional ash discharging gear provides a kind of recirculating fluidized bed biomass boiler with runner ash discharging gear.
The utility model is realized through following technical proposals:
A kind of recirculating fluidized bed biomass boiler with runner ash discharging gear; Comprise boiler furnace, hearth wall, flue, cyclone, dry ash cooler and runner ash discharging gear; Said cyclone comprises air inlet, air outlet and ash-collecting port, and said air inlet is connected with said boiler furnace, and said air outlet is connected with said flue; Said dry ash cooler one end is connected with said ash-collecting port, and the other end is connected with said runner ash discharging gear.
Said runner ash discharging gear comprises motor, gearbox, runner shell, two runner dishes, runner shaft, ash inlet and ash holes; Said runner dish and runner shell center are provided with shaft hole, and said runner shaft is located in the shaft hole, and pass through bearing bracket stand on the runner shell; Said runner shaft one end is connected with motor through gearbox; Said ash inlet is located at said runner shell upper, and is connected with said dry ash cooler, and said ash hole is located at said runner outer casing underpart.
Be provided with some dividing plates that divergent shape distributes that are between said two runner dishes, form some segment cavitys with said runner shell.
The beneficial effect that the utility model brought is:
In the utility model, said recirculating fluidized bed biomass boiler with runner ash discharging gear has following advantage:
⑴ can directly go out dry ash, reduces the secondary pollution because of going out to wet ash, reduces ash content and run off.
⑵ runner is rounded, and multilayer insulating panel is radial arrangement, no matter the ash amount what can both keep good air-tightness, reduce that boiler leaks out and the hot gas accident that leaks outside take place because of detonation.
⑶ runner internal fan body void space is big, and ash discharge moves downward all the time, has the bulk object also to be not easy the cause clogging accident.
