Abstract
The utility model relates to a circulating fluidized bed boiler fly ash storage device belongs to the circulation fluidized bed technology field, a plurality of ash hopper of dust collector including furnace and furnace one side still include ashes storage silo, and ash hopper of dust collector is connected through an ash conveying pipe to the ashes storage silo import, and furnace is connected through the 2nd ash conveying pipe to the ashes storage silo export, and the ashes storage silo upper end is equipped with the dust remover, and the ashes storage silo lower extreme is equipped with furnace 2, and furnace 2 connects furnace 4, is equipped with the charge level indicator on the ashes storage silo lateral wall. The device simple structure, the assurance is returned grey incessantly, and is continuously combustion -supporting, advances the ash, goes out the ash smoothness, and the economic nature of burning is good, energy saving and consumption reduction, reduction emission.
Description
Technical field
The utility model is related to a kind of CFBB flying dust storage device, belongs to Technology of Circulating Fluidized Bed Boiler neck
Domain.
Background technology
A large amount of flying dusts can be produced, existing flying dust is collected by dust collector ash hopper in CFBB running,
Then the flying dust in dust collector ash hopper is sent back to again by pipeline and in burner hearth, carry out the combustion-supporting continuous operation ensureing boiler.Existing
There is structure to be that dust collector ash hopper passes through pipeline and directly connects burner hearth, the situation of gray back interruption occurs in the course of work it is impossible to protect
Card is lasting combustion-supporting, reduces efficiency of combustion.
Utility model content
According to deficiency of the prior art above, the technical problems to be solved in the utility model is: provides a kind of recycle stream
Fluidized bed boiler flying dust storage device, it is ensured that gray back is uninterrupted, continues combustion-supporting.
CFBB flying dust storage device described in the utility model, removes including burner hearth and some of burner hearth side
Dirt device ash bucket, also includes ash-storing bin, and ash-storing bin import is passed through the first ash conveying pipe and connected dust collector ash hopper, and ash-storing bin outlet is passed through
Second ash conveying pipe connects burner hearth, and ash-storing bin upper end is provided with deduster, and ash-storing bin lower end is provided with back-flushing valve, and back-flushing valve connects compression
Air hose, ash-storing bin side wall is provided with level-sensing device.
During work, the flying dust of dust collector ash hopper passes through the first ash conveying pipe and enters ash-storing bin, and ash-storing bin is independent additional
Structure, it is ensured that uninterrupted gray back, is then passed through the second ash conveying pipe and is sent in burner hearth；Ash-storing bin top design is installed independent
It is ensured that entering grey smooth, bottom design installs independent back-flushing valve to deduster, and in prevention storehouse, the overstocked outflow of dust stratification is not smooth.
Preferably, the deduster of ash-storing bin upper end is sack cleaner.
The utility model is compared with prior art had the beneficial effect that
CFBB flying dust memory device structure is simple, installs independent ash-storing bin additional it is ensured that gray back is uninterrupted, continues
Combustion-supporting, independent deduster is installed and back-flushing valve ensures that, into ash, ash discharge smoothness, combustion economization is good, energy-saving, minimizing row
Put.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure: 1, burner hearth；2nd, dust collector ash hopper；3rd, the first ash conveying pipe；4th, deduster；5th, ash-storing bin；6th, level-sensing device；7、
Back-flushing valve；8th, the second ash conveying pipe.
Specific embodiment
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further:
As shown in figure 1, CFBB flying dust storage device includes burner hearth 1 and some dedusters of burner hearth 1 side
Ash bucket 2, also includes ash-storing bin 5, and ash-storing bin 5 import connects dust collector ash hopper 2 by the first ash conveying pipe 3, and ash-storing bin 5 outlet is logical
Cross the second ash conveying pipe 8 and connect burner hearth 1, ash-storing bin 5 upper end is provided with deduster 4, and ash-storing bin 5 lower end is provided with back-flushing valve 7, back-flushing valve
7 connection compressed air hoses, ash-storing bin 5 side wall is provided with level-sensing device 6.
The deduster 4 of ash-storing bin 5 upper end is preferably sack cleaner.
During work, the flying dust of dust collector ash hopper 2 enters ash-storing bin 5 by the first ash conveying pipe 3, then passes through the second defeated ash
Pipeline 8 is sent in burner hearth 1；Additional ash-storing bin 5 can ensure that uninterrupted gray back, deduster 4 and back-flushing valve 7 ensure into ash, ash discharge
Smoothly, height of materials information in level-sensing device 6 prompting storehouse.
