Description
Technical field
The present invention relates to a kind of device that utilizes boiler afterheat to prepare coal dust.
Background technology
At present; The main energy sources of China is main with coal still; Except that large-scale power station, power plant with (the coal dust burn-off rate is up to more than 99%) the advanced pulverized coal combustion, other burnings are main with traditional chain grate furnace and fluidized bed furnace still, particularly chain grate furnace burn-off rate less than 85%; Waste energy again, again serious environment pollution.Selecting coal dust firing has been the main trend of current social development, and energy-conservation so again, environmental protection again is so the coal grinding device also just becomes a key link of coal dust firing.Existing coal grinding device complex structure, moral conduct is inconvenient, is difficult to realize automation control.
Summary of the invention
The invention provides a kind of device that utilizes boiler afterheat to prepare coal dust, this apparatus structure is simple, and moral conduct is convenient, has realized automation control.
In order to achieve the above object, the present invention has taked following technical scheme.This device comprises coal bunker, first feeder, first elevator, coal store, second feeder, conveyer, boiler afterheat baking oven, grinding machine, second elevator and powder-storage bin.Wherein: first feeder, first elevator, coal store, second feeder, conveyer, grinding machine, second elevator are connected with powder-storage bin successively, and coal bunker is arranged in to directly over first feeder, the boiler afterheat baking oven be arranged in conveyer under.This device directly shovels coal in the coal bunker with loading machine; Evenly descend coal on request by first feeder; Be transported to coal in the coal store through first elevator, send into conveyer by second feeder again, the boiler afterheat baking oven carries out heating, drying to coal simultaneously; The coal of having dried moisture gets in the grinding machine and grinds, and grinds qualified coal dust and gets in the powder-storage bin through second elevator.
This device also comprises sack cleaner, and an end of sack cleaner is connected with grinding machine, and the other end is connected with second elevator.Sack cleaner carries out dust removal and filtration to the lingering remnants of past customs etc., and the coal dust that filters gets into second elevator, also promotes at last and gets into powder-storage bin.
Advantage of the present invention is: simple in structure, moral conduct is convenient, has realized automation control, has reduced the amount of labour, has improved working environment, and output is high, quality is good, cost is low, for coal-powder boiler fully burns guarantee is provided.
