Description
Technical field
This utility model relates to recirculating fluidized bed biomass boiler field, is specifically related to a kind of recirculating fluidized bed biomass boiler deslagging
Device.
Background technology
Utilizing field at biomass comprehensive at present, direct combustion power generation is still in occupation of leading position, and biomass direct combustion power generation utilizes exactly
Biomass boiler to biomass directly burn absorb heat energy produce steam with pushing turbine electromotor produce electric energy generating work
Skill.In the technique of this biomass direct combustion power generation, efficiency is the highest, and the most widely used is exactly recirculating fluidized bed biomass boiler.
Due to the complicated variety of biomass fuel, collect at it and during transport, earth, stone etc. can be mixed unavoidably non-
The non-combustible impurity of biomass.Such impurity not only can not burn, and substantial amounts of impurity can be assembled in siege, and this is accomplished by
The outer deslagging of high frequency.
In the design of conventional recirculating fluidized bed biomass boiler, its scum pipe is single straight tube, tube inlet unprotect and
, the most often there is plugging phenomenon in agitation facility.
For the problems referred to above, operation is arranged outside frequently with slag when manually disclosing the measure of slag to realize plugging, but this behaviour
Make i.e. it cannot be guaranteed that continuous discharging slag, there is also the biggest operation simultaneously and scald risk.
Utility model content
This utility model provides a kind of recirculating fluidized bed biomass boiler slag-discharging device, effectively prevents the scum pipe mouth of pipe from blocking, and improves
Deslagging effect.
The technical solution of the utility model is: include outer scum pipe, interior scum pipe, protection cage, plate turnover ash discharge valve, described outside
Scum pipe is sheathed on outside interior scum pipe, and interior scum pipe can rotate in scum pipe outside, and interior scum pipe is longer than outer scum pipe, described anti-
Protect cage and plate turnover ash discharge valve is respectively arranged on interior scum pipe two ends.
Preferred as such scheme, described protection cage one end open, opening is connected with the interior scum pipe mouth of pipe, including many longitudinal directions
Protection cage stud and lateral circular protection cage circle muscle outside many root guards cage stud, constitute the caged that can prevent interior scum pipe from blocking
Structure.
Preferred as such scheme, on described interior scum pipe, outer wall near plate turnover ash discharge valve side is provided with turning of extending radially
Fixed handle.
Preferred as such scheme, described turning handle is shaft-like, is circumferentially evenly distributed with multiple at interior scum pipe outer wall
Preferred as such scheme, the end that described interior scum pipe is connected with protection cage is provided with the annular spacing groove outwards turned down,
Described outer scum pipe end is located in described annular spacing groove, and described protection cage is set in described annular spacing groove outer wall.
The beneficial effects of the utility model are:
1, the slag-discharging device that this utility model provides does not haves the blocking of slag dropping tube.
2, by operation turning handle, in that context it may be convenient to realize the agitation of slag, make slag effluent stream smooth and operation safety.
3, be effectively reduced boiler due to deslagging blocking and cause be forced blowing out, improve the availability of boiler.

Detailed description of the invention
Embodiment of the present utility model is described in detail, it is clear that described embodiment is only this utility model one below in conjunction with accompanying drawing
Section Example rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not having
Have and make the every other embodiment obtained under creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figures 1 to 4, the present embodiment includes outer scum pipe 3, interior scum pipe 4, protection cage, plate turnover ash discharge valve 8, institute
Stating outer deslagging pipe box 3 to be located at outside interior scum pipe 4, interior scum pipe 4 can rotate, outside interior scum pipe 4 is longer than in scum pipe 3 outside
Scum pipe 3, described protection cage and plate turnover ash discharge valve 8 are respectively arranged on interior scum pipe 4 two ends.
In the present embodiment, described protection cage one end open, opening is connected with interior scum pipe 4 mouth of pipe, including many longitudinally protection
Cage stud 5 and the lateral circular protection cage circle muscle 6 outside many root guards cage stud 5, constitutes and can prevent interior scum pipe 4 from blocking
Cage structure.
In the present embodiment, on described interior scum pipe 4, the outer wall of close plate turnover ash discharge valve 8 side is provided with the rotation extended radially
Handle 7.
In the present embodiment, described turning handle 7 is shaft-like, is circumferentially evenly distributed with four at interior scum pipe 4 outer wall.
In the present embodiment, the end that described interior scum pipe 4 is connected with protection cage is provided with the annular spacing groove of outwards turnover, institute
Stating outer scum pipe end to be located in described annular spacing groove, described protection cage is set in described annular spacing groove outer wall.
Described outer scum pipe 3 is installed on boiler grid plate 2 and through boiler bellows 9, boiler air box plate 2 stretches out boiler
Body, interior scum pipe 4 movable set in outer scum pipe 3, between interior scum pipe 4 and outer scum pipe 3 can with flexible rotating,
And the annular spacing groove outwards turned down by interior scum pipe 4 top carries out opposing seal.Protection is installed on the top of interior scum pipe 4
The stone of bulk, to prevent the interior scum pipe 4 of ratchel blocking in fuel, can be blocked in and protect beyond cage by cage.At interior scum pipe 4
Stretch out the bottom outside boiler and turning handle 7 be installed, the slag that this turning handle 7 is piled up with agitation scum pipe entrance can be operated,
Be beneficial to deslagging, for the safety operated, it is also possible to add on turning handle 7 set steel pipe to extend the operative radius of this handle,
Make operator away from high temperature deslagging.The lower end of interior scum pipe 4 is provided with plate turnover ash discharge valve 8, to control to arrange outside slag.
