Description
Technical field
The utility model relates to the auxiliary equipment of fluidized-bed combustion boiler more particularly to a kind of circulating fluidized bed boiler to install bed material additional
Device.
Background technique
Circulating fluidized bed boiler is the highest clean coal combustion technology of industrialization degree.Circulating fluidized bed boiler uses fluidised form
Change burning, primary structure includes combustion chamber (including emulsion zone and dilute-phase zone) and circulation melt down (including high-temperature gas-solid separator with
Revert system) two large divisions.Maximum difference with bubbling fluidized bed combustion technology is operating air velocity height, enhances burning and desulfurization
Etc. heterogeneous reactions process, boiler capacity can be expanded to power industry acceptable large capacity (600MW or ratings above)
Currently, circulating fluidized bed boiler underlying issues and expansion, abrasion, the overtemperature such as very good solution calorifics, mechanics, materialogy
Equal engineering problems become fire retardant solid fuel (such as gangue, oil shale, municipal refuse, mud and other wastes) energy benefit
Advanced technology.
Circulating fluidized bed boiler need to install a certain amount of bottom ash additional as igniting starting bed material when starting, and original bed material installs additional
Mode is that artificial installation is shakeout after the bed material being sieved is transported to operating layer by being manually transported to burner hearth by boiler manhole door,
I takes around the side's 70-80 bed material at company 480t/h circulating fluidized bed boiler one-shot bed material, and artificial install additional needs 2-3 days,
Bed material installs overlong time, serious shadow to unit starting time additional.
Utility model content
The utility model has saved boiler and has installed bed material additional by providing a kind of circulating fluidized bed boiler installation bed material device
Time realizes boiler feeding and deslagging using set of device simultaneously.The utility model is achieved by the following technical solution.
A kind of circulating fluidized bed boiler installation bed material device, including circulating fluidized bed boiler, further include bucket elevator, defeated
Machine and slag library are sent, the feeding inlet of circulating fluidized bed boiler is connected by first pipe with the outlet of bucket elevator, described
The outlet of bucket elevator is connected by second pipe with the slag library, is set respectively on the first pipe and second pipe
It is equipped with gate valve, the bottom of the bucket elevator is connected with conveyer.
Further, the conveyer is bucket chain conveyor.
Further, the outlet of the bucket elevator is connected with first pipe and second pipe respectively by threeway
It is logical.
Further, the side wall of circulating fluidized bed boiler is arranged in the feeding inlet of the circulating fluidized bed boiler.
The utility model is generated compared with the existing technology to be had the beneficial effect that.
The utility model will be combined into one with to boiler slag removal for circulating fluidized bed boiler extra bed material, realize quick feeding and
The purpose of discharge.The present apparatus saves boiler and installs the bed material time additional, and the previous artificial bed material that installs additional needs 2-3 days, installs bed additional after improvement
Material needs 4-5 hour, and each unit maintenance is complete after improvement can shift to an earlier date starting in 1.5-2.5 days more in the past, every time can multiple electric 4,000,000
KWh increases by 1,320,000 yuan of operating income.Secondly, reducing bed material installs expense additional, therefore expense can be saved by once installing bed material additional after improving
With 1.08 ten thousand yuan, it can be saved bed material by unit starting 10 times calculating, whole year and be installed additional 10.8 ten thousand yuan of expense within 1 year.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 is circulating fluidized bed boiler, and 2 be bucket elevator, and 3 be conveyer, and 4 be slag library, and 5 be first pipe, 6
It is gate valve for second pipe, 7.
Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, tie
Embodiment and attached drawing are closed, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein
It is only used to explain the utility model, is not used to limit the utility model.This is described in detail below with reference to examples and drawings
The technical solution of utility model, but the scope of protection is not limited by this.
As shown in Figure 1, a kind of circulating fluidized bed boiler installs bed material device, including circulating fluidized bed boiler 1 additional, it further include bucket
The feeding inlet in formula elevator 2, conveyer 3 and slag library 4, circulating fluidized bed boiler 1 passes through first pipe 5 and bucket elevator 2
Outlet is connected, and the outlet of bucket elevator 2 is connected by second pipe 6 with slag library 4, in first pipe 5 and second pipe 6
It is respectively arranged with gate valve 7, the bottom of bucket elevator 2 is connected with conveyer 3.Conveyer 3 is bucket chain conveyor.
The outlet of bucket elevator 2 is connected with first pipe 5 and second pipe 6 respectively by threeway.
The side wall of circulating fluidized bed boiler 1 is arranged in the feeding inlet of circulating fluidized bed boiler 1.
Specific embodiment are as follows: one threeway is set in 2 top exit pipeline of bucket elevator, the threeway is by bucket lifting
2 outlet conduit of machine is divided into two-way, is connected to slag library 4 all the way, another way is connected to the pipeline of circulating fluidized bed boiler 1 into burner hearth.
When installing bed material additional, the gate valve 7 on second pipe 6 is closed, opens the gate valve 7 of first pipe 5, while starting air-introduced machine, First air
