Description
Technical field
The present invention relates to power plant auxiliary machine technical field is and in particular to a kind of power plant auxiliary machine dry type slag remover for boilers.
Background technology
How using dry bottom ash handling system, the bottom ash of coal-burning boiler to be processed in steam power plant at present, dry slag disposal equipment
Work process is the conveying that the hot slag discharging boiler falls dry type conveyer after slag-removing hopper, precrushing hydraulic shutoff door
On band, and move with the conveyer belt slowly moving.The two side of dry type conveyer, head and afterbody are respectively equipped with several
Air inlet, using the swabbing action of combustion chamber draft, sucks cold air on the spot, assists partly to have failed on conveyer belt using cold air
The combustible of full burning further burns, and absorbs slag high temperature heat content, the middle temperature that cooling of furnace slag is 100～200 DEG C
Lime-ash；In the heat exchange with slag, own temperature will rise to 300～400 DEG C to cold air, subsequently into boiler；In order to not
Impact boiler efficiency, the cooling air volume entering dry slag conveyer must be less than or equal to the 1% of boiler combustion air quantity.It is cooled
Slag, then crusher in crushing is entered by tape transport, broken after slag finally enter middle slag storehouse or fall directly into slag
Storage is deposited.Existing dry slag disposal equipment easily plays ash and the problem of slag abrasion conveyer device in slagging-off transportation,
Limit the normal operation of dry type slag remover for boilers to a certain extent.
Content of the invention
Not enough for prior art, the invention provides a kind of dedusting, antiwear power plant auxiliary machine dry type slag-eliminating set
Standby.
The present invention solve above-mentioned technical problem adopt technical scheme be：A kind of power plant auxiliary machine dry type slag remover for boilers,
Including slag crusher, pressure fan, conveyance conduit, cleaner unit, storage silo；Described conveyance conduit is in the form of a column hollow cavity, described conveying
Pipeline side along its length is provided with opening；Described slag crusher passes through described opening and slag charge puts into the one of conveyance conduit
End；Described pressure fan is placed in one end of conveyance conduit opening；Slag crusher is arranged on described conveyance conduit opening one side ducts, described
The other end of conveyance conduit connects cleaner unit；Described cleaner unit is pulsed cloth bag dust exhaust apparatus, for discharging from described air-supply
The dust carrying in release air-flow in machine.
Further, described conveyance conduit opening one upper lateral part is provided with sprayer unit.
Further, setting sealing air door at described conveyance conduit opening；Described sealing air door is used for opening and closing institute
State the opening on conveyance conduit.
Further, described cleaner unit includes multiple air draft cloth bags；Multiple described air draft cloth bags are placed in described cleaner unit
Side.
The advantage that the present invention possesses：
A kind of power plant auxiliary machine dry type slag remover for boilers that the present invention provides, is transported by carrier bar and guipure with of the prior art
The slag removal equipment of the cinder pulverized is compared, and its cinder being put into by the wind that pressure fan blows out in conveyance conduit passes through delivery pipe
Behind road, blow into storage silo, and then achieve the transport to cinder, save substantial amounts of transport part, it also avoid due to
Device loss that mechanical part abrasion leads to and the maintenance cost that causes and work hidden danger；Meanwhile, conveyance conduit peristome setting
Sprayer unit be effectively increased the humidity that pressure fan is blown into air, reduce the yield of dust, it is to avoid it exports in conveyance conduit
Discharge dust to storage silo in environment, and contribute to dust arrester dedusting；Pulsed sack cleaner overhauls
Convenient, also extend life of equipment, thoroughly improve equipment and personnel's production work environment simultaneously, improve capacity utilization and
Service life.
