Description
Technical field:
The utility model relates to a kind of boiler system more particularly to a kind of boiler systems using the ash that gives up.
Background technique:
As discharge standard is increasingly stringent, flue gas could discharge after needing abundant desulfurization when boiler combustion.Therefore, boiler exists
It needs to spray into when work desulfurizing agent (lime stone), the sulfur dioxide that coal combustion generates generates sulfate with reactive desulfurizing agent and stays in
In useless ash, the discharge of sulfur dioxide is reduced.
In the solid by-product that boiler generates, 70%-90% is accounted for the flying dust that flue gas is discharged together, boiler bottom discharge
Useless ash accounts for 30%-10%；In power plant or chemical plant boiler operatiopn, temperature is generally up to 990 DEG C in the burner hearth of boiler, and desulfurization
The optimum temperature section of denitration is 870-920 DEG C, and the method for temperature control of boiler is recycled back by the flying dust that boiler itself generates
In furnace, still, since flying dust temperature is up to 900 DEG C or so, when using flying dust adjustment fire box temperature, often cooling extent is not
Greatly, it is difficult to reach requirement.
Further, since the useless grey yield that generates of boiler combustion is small and pollution is relatively small, people to its not enough attention,
Useless ash is not recycled.But since boiler needs to spray at work excessive desulfurizing agent, and most of excessive desulfurizing agent
It focuses in useless ash, CaO content is up to 50% or more in the useless ash that boiler generates, and in the prior art, useless ash is not recycled
It is directly discarded, cause the significant wastage of desulfurizing agent.
Utility model content:
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of boiler systems using the ash that gives up.
The utility model is implemented by following technical solution: a kind of boiler system using the ash that gives up, including the storage of boiler, desulfurizing agent
Library, grey library and crusher；The desulfurizing agent storage cavern is connected to the boiler by desulfurizing agent conveyance conduit, the desulfurizing agent conveying
The outlet of one end of pipeline and the desulfurizing agent storage cavern, the other end of the desulfurizing agent conveyance conduit and taking off for the boiler
The connection of sulphur agent entrance；Desulfurizing agent delivery pump is equipped on the desulfurizing agent conveyance conduit；
The ash hole of the boiler and the entrance of crusher connect, and the outlet of the crusher and the entrance in the grey library are logical
Piping connection；
The outlet in the ash library is connected to the desulfurizing agent conveyance conduit by useless grey conveyance conduit, in the useless ash conveying
Pipeline is equipped with useless grey delivery pump.
Further, desulfurizing agent regulating valve is equipped on the desulfurizing agent conveyance conduit.
Further, on the desulfurizing agent conveyance conduit between the desulfurizing agent storage cavern and the useless grey conveyance conduit
Equipped with the desulfurizing agent regulating valve.
Further, useless grey regulating valve is equipped on the useless grey conveyance conduit.
Further, the entrance of the ash hole of the boiler and crusher is connected by conveyer.
In power plant or chemical plant boiler operatiopn, temperature is generally up to 990 DEG C in the burner hearth of boiler, and desulphurization denitration is most
Good temperature range is 870-920 DEG C, therefore by the recycling for the ash that gives up, reduces temperature in the burner hearth of boiler first, make boiler
Temperature control is in the optimum temperature section of desulphurization denitration in burner hearth；Secondly by the recycling of useless ash, take full advantage of in useless ash
CaO, can be effectively reduced the dosage of desulfurizing agent lime stone, reduce desulphurization cost.
The advantages of the utility model: the utility model structure is simple, by the recycling for the ash that gives up, not only reduces boiler
Temperature in burner hearth controls temperature in boiler furnace in the optimum temperature section of desulphurization denitration；And it takes full advantage of in useless ash
CaO, can be effectively reduced the dosage of desulfurizing agent lime stone, reduce desulphurization cost.
Detailed description of the invention:
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of boiler system structural schematic diagram using the ash that gives up of the present embodiment.
In figure: boiler 1, desulfurizing agent storage cavern 2, grey library 3, crusher 4, desulfurizing agent conveyance conduit 5, desulfurizing agent delivery pump 6 are defeated
Machine 7 is sent, give up ash conveyance conduit 8, desulfurizing agent regulating valve 9, and ash regulating valve 10 of giving up, give up ash delivery pump 11.
Specific embodiment:
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
