Abstract
The utility model discloses an utilize device of industry circulating fluidized bed boilerslagremoval heating bunker coal, including circulating fluidized bed boiler, sediment storehouse, air -blower and bunker coal heating cabinet, the circulating fluidized bed boiler is equipped with row cinder notch and is connected with the scum pipe that leads to the sediment storehouse, and the sediment storehouse is big -end -up's toper structure, and one side of sediment storehouse bottom is equipped with the air intake to be connected with the air -supply line that leads to the air -blower, the one side on sediment storehouse upper portion is equipped with the air outlet, and is connected with the play tuber pipe that leads to the bunker coal heating cabinet, is equipped with the air exit on the bunker coal heating cabinet and is connected with the exhaust pipe. The utility model discloses use in the industry field, make full use of in the boiler discharge waste residue remaining heat, both avoided also having practiced thrift the fire coal simultaneously because coal high humidity and canopy coal phenomenon have reduced the coal and at furnace internal absorption heat, has solved the difficult problem in the production, improved the boiler efficiency effect.
Description
Technical field
The utility model relates to industrial thermal cycle and utilizes device field, specifically a kind of device utilizing industrial circulating fluid bed boiler deslagging heating fuel coal.
Background technology
Generally adopt CFBB at present in the industrial production, this boiler energy-saving environmental protection, but, its slag of discharging has higher temperature, if do not carry out utilizing this part heat energy to slattern in vain, and the moisture in coal that many production units often enter stove due to rainproof bad or other reason of coal canopy is larger, not only can block defeated coal channel but also the larger coal of humidity to enter in burner hearth and also will absorb many heats, many producers are blocked for the coal handling system caused because coal wets take respectively vibrating head is installed, transform the ways such as defeated coal mode to solve, but effect is not too desirable, and wet coal enters burner hearth and absorbs the problem of heat and also cannot solve.Therefore, minimum cost how can be utilized the bunker coal heating, drying entered in burner hearth, be the solution that many producers are making great efforts to seek.
Utility model content
The purpose of this utility model is to provide a kind of device utilizing industrial circulating fluid bed boiler deslagging heating fuel coal, the heat heating fuel coal utilizing CFBB deslagging remaining, avoid the canopy coal phenomenon because of coal high humidity to additionally reduce coal in burner hearth, absorb heat, save fire coal to reach, improve the object of boiler thermal output.
The technical solution of the utility model is as follows:
A kind of device utilizing industrial circulating fluid bed boiler deslagging heating fuel coal, include CFBB, slag storehouse, air blast and bunker coal heating cabinet, it is characterized in that: described CFBB is provided with slag-drip opening and is connected with the scum pipe leading to described slag storehouse, described slag storehouse is up big and down small pyramidal structure, side bottom slag storehouse is provided with air inlet, and be connected with the blast pipe leading to described air blast, the side on top, slag storehouse is provided with air outlet, and be connected with the discharge pipe leading to described bunker coal heating cabinet, described bunker coal heating cabinet is provided with exhaust outlet and is connected with exhaust duct.
The described device utilizing industrial circulating fluid bed boiler deslagging heating fuel coal, is characterized in that: be provided with residual cake valve in described scum pipe.
The described device utilizing industrial circulating fluid bed boiler deslagging heating fuel coal, is characterized in that: the bottom in described slag storehouse is provided with slag tap and is connected with slag-discharge pipe, is provided with deslagging valve in described slag-discharge pipe.
The wind heating that the utility model utilizes the warm sludge with higher temperature of discharging from fluidized-bed combustion boiler to be blown by air blast, wind after heating enters bunker coal heating cabinet and bunker coal generation heat exchange thus heating fuel coal, bunker coal water content after heating declines, temperature raises, both avoided because coal high humidity and canopy coal phenomenon additionally reduce coal and absorb heat in burner hearth, reach and save fire coal, improve the good result of boiler thermal output.
The beneficial effects of the utility model:
The utility model is applied in industrial circle, take full advantage of boiler and discharge heat remaining in useless waste residue, both avoided because coal high humidity and canopy coal phenomenon additionally reduce coal and absorb heat in burner hearth, and solved the difficult problem in production, also save fire coal simultaneously, improve boiler thermal output effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
See Fig. 1, a kind of device utilizing industrial circulating fluid bed boiler deslagging heating fuel coal, include CFBB 1, slag storehouse 2, air blast 3 and bunker coal heating cabinet 4, CFBB 1 is provided with slag-drip opening and is connected with the scum pipe 5 leading to slag storehouse 2, slag storehouse 2 is up big and down small pyramidal structure, side bottom slag storehouse 2 is provided with air inlet, and be connected with the blast pipe 6 leading to air blast 3, the side on top, slag storehouse 2 is provided with air outlet, and be connected with the discharge pipe 7 leading to bunker coal heating cabinet 4, bunker coal heating cabinet 4 is provided with exhaust outlet and is connected with exhaust duct 8.
In the utility model, residual cake valve 9 is installed in scum pipe 5.
The bottom in slag storehouse 2 is provided with slag tap and is connected with slag-discharge pipe 10, is provided with deslagging valve 11 in slag-discharge pipe 10.
Bunker coal is transported in bunker coal heating cabinet 4, when CFBB 1 normal operation, close deslagging valve 11, open residual cake valve 9, after warm sludge is filled up in slag storehouse 2, close residual cake valve 9, open air blast 3, the wind that air blast 3 bloats is on warm sludge, thus keep watch and be heated to certain temperature, then, this hot blast is admitted to bunker coal heating cabinet 4, contact with the bunker coal in it, play heating fuel coal, the effect of evaporation moisture in coal, steam and unnecessary wind are then discharged through exhaust duct 8, until after the moisture in bunker coal is taken away substantially, bunker coal can be sent in burner hearth and burn.
During slagging, close air blast 3, open deslagging valve 11, after all being bled off by the slag in slag storehouse 2, close deslagging valve 11, open residual cake valve 9, after warm sludge is filled up in slag storehouse 2, close residual cake valve 9, open air blast 3, namely complete one and take turns all operations process.
The warm sludge of what the utility model utilized CFBB to discharge have higher temperature, the wind bloated by air blast is taken away the heat in warm sludge, and contact with bunker coal, thus reach the effect of heating, drying bunker coal, whole process is without any need for the input of thermal source cost, and thermal source is stablized.
