Technical field
The utility model relates to the burnt ash-discharging device of dry quenching field recyclegas system time dust collector, particularly a kind of dry coke quenching first and second dust exhaustor.
Background technology
Dry quenching technology utilizes inertia recyclegas to carry out with red-hot coke the sensible heat that interchange of heat absorbs red-hot coke dry putting out in stove, then by other function devices in system to the process utilized by the recyclegas after heating, thus reach the object of UTILIZATION OF VESIDUAL HEAT IN.
The important function device of dry coke quenching auxiliary comprises and dryly puts out the equipment such as stove, circulating fan, boiler, recycle gas line
The tiny flour particle of cooled coke can absorb in the process of sensible heat and mixes with carrying out at the dry recyclegas put out in stove interchange of heat, then enters recycle gas line, by the equipment such as circulating fan, boiler.
Due to the particularity of circulating fan and boiler plant, strict restriction is had for the dust granules content in recyclegas, must process it by arranging dust exhaustor, to ensure the normal service life of equipment in recycle gas line, so dedusting and unload grey equipment and just seem particularly important.
The equipment that unloads in the past adopts the coke powder cooling intallation arranging meet requirements below dust exhaustor, form unloading valve is set at the cinder-discharging port of coke powder cooling intallation and interlocks to the corresponding level-sensing device arranged on coke powder cooling intallation, the intrasystem DCS control system of access dry coke quenching auxiliary controls automatically to ash-valve, is then carried by the defeated grey equipment of independent operating the coke powder of being discharged by form unloading valve, transports outward.
The defeated grey equipment of independent operating generally has two kinds of modes, and the first is connected with form unloading valve by arranging slat conveyer, mechanically the ashes of discharging is collected, is processed; The second is connected with form unloading valve by arranging pneumatic delivery bin pump, mechanically the ashes of discharging collected, processed; And the first utilizes scrapper conveyor to carry out the defeated grey process of mechanical system and unreliable, there is the situation of the how easy generation reentrainment of dust of leak source, and the second utilizes the mixture of airstream and strength to carry out the mode of defeated ash, due to the structure of equipment itself, and the reason of form valve service conditions can not carry out direct interlocked control, can only by defeated grey equipment separately outside dry coke quenching auxiliary system DCS control system, therefore can not facilitate in center-control indoor, intuitively it controlled and show, thus cause all inconvenience and problem in production run process.
Utility model content
The purpose of this utility model is to provide the burnt ash-discharging device of a kind of dry coke quenching first and second dust exhaustor efficiently, so as to solve the burnt ash-discharging device of dry coke quenching first and second dust exhaustor in the past and coke dry quenching body control system separate, can not control it convenient in Central Control Room, intuitively and show, thus improve the automatic operating degree of system, reduce the labour intensity of workman and improve working environment, increase work efficiency.
To achieve these goals, the utility model by the following technical solutions, the burnt ash-discharging device of a kind of dry coke quenching first and second dust exhaustor, at least comprise: coke powder cooling unit, unload grey push-pull valve, the first form unloading valve, coke powder intermediate bin, storehouse pump intake valve, pneumatic transporting ash silo pump, ash handing pipeline, ash silo, wetting stirrer, Cang Beng fluidising chamber, described coke powder cooling unit upper end is connected respectively with dry quenching system one secondary filter, receives the coke powder and particle separated by dust exhaustor and cools; The discharging opening of described coke powder cooling unit lower end with unload grey push-pull valve upper end and be connected, the described lower end of unloading grey push-pull valve is connected with the upper end of the first described form unloading valve; The lower end of the first described form unloading valve is connected with coke powder intermediate bin entrance; Be connected by storehouse pump intake valve between coke powder intermediate bin with pneumatic transporting ash silo pump.
The upper end of described pneumatic transporting ash silo pump is connected with storehouse pump intake valve, the outlet of Cang Beng fluidising chamber is connected with ash handing pipeline, ash silo is delivered to by ash handing pipeline by after the coke powder fluidisation in the pump of storehouse, the second form unloading valve then by being arranged on ash silo is discharged, after enter wetting stirrer, humidification stir after discharged by exhaust tube.
Described coke powder cooling unit upper end is barreled structure, and lower end is funnel-form.
Described coke powder intermediate bin upper end is barreled structure, and lower end is funnel-form.
Described ash silo upper end is barreled structure, and lower end is funnel-form.
Described wetting stirrer horizontal positioned, lower end connects exhaust tube.
The utility model has the advantages that: because the pressure in the work section below work section more than form unloading valve and storehouse pump intake valve is different, so directly can not connect thus cause the situation of defeated grey equipment independent operating, be therefore provided with coke powder intermediate bin and transition, buffering are carried out to it; In addition, the upper end of pneumatic transporting ash silo pump is connected with storehouse pump intake valve, the outlet of Cang Beng fluidising chamber is connected with ash handing pipeline is then discharged after the coke powder fluidisation in the pump of storehouse by the form unloading valve being arranged on ash silo to ash silo by Pipeline transport, after enter wetting stirrer, humidification stir after discharged by exhaust tube.Thus improve the automatic operating degree of system, reduce the labour intensity of workman and improve working environment, increase work efficiency.
