Description
Technical field
The utility model relates to a kind of blast-furnace coke heating, drying device.Belong to metal metallurgy smelting equipment technical field.
Background technology
In blast furnace process is produced, coke moisture content number directly have influence on fuel consumption.As shown in Figure 1, it is exactly a simple feed bin structure to the coke bin in the past adopting, and STRENGTH ON COKE moisture content is uncontrollable, and when coke moisture content exceedes 7%, coke powder will be bonded on coke briquette, thereby makes a large amount of powder enter stove.Moisture content and coke blacking directly affect fuel consumption.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of blast-furnace coke heating, drying device is provided, and it can reduce coke moisture content, reduces coke powder and enters stove.
The purpose of this utility model is achieved in that a kind of blast-furnace coke heating, drying device, comprise coke bin, described coke bin bottom bulkhead is provided with multiple air inlets, and multiple air inlets are all connected with blast pipe, blast pipe is connected with air blast, and air blast is connected with flue; Described coke bin top bulkhead is provided with multiple feed bins inlet scoop, multiple feed bins inlet scoop is all connected with discharge pipe, discharge pipe is connected with cleaner air inlet, and cleaner air outlet is connected with air exhauster air inlet, air exhauster air outlet with enter hot-blast stove flue pipe and be connected.
Compared with prior art, the beneficial effects of the utility model are:
With flue gas waste heat recovery heating coke such as hot-blast stoves, increase coke temperature by heating, reduce coke and enter stove moisture content, reduce coke powder and enter stove, reduce stove dirt in furnace charge and blow out, alleviate dedusting load, slow down blade wear.Reduce fuel consumption and equipment attrition.
Accompanying drawing explanation
Fig. 1 is the coke bin structural representation in the past adopting.
Fig. 2 is the utility model blast-furnace coke heating, drying apparatus structure schematic diagram.
Reference numeral in figure:
Coke bin 1
Air inlet (2 ~ 4) 5
Feed bin inlet scoop (5) 6
Air exhauster 9
Enter hot-blast stove flue pipe 10.
The specific embodiment
Referring to Fig. 2, Fig. 2 is the utility model blast-furnace coke heating, drying apparatus structure schematic diagram.As seen from Figure 2, the utility model blast-furnace coke heating, drying device, comprise coke bin 1, it is 4 that described coke bin 1 bottom bulkhead is provided with in 2 ~ 4 air inlet 5(figure), 2 ~ 4 air inlets 5 are all connected with blast pipe 4, blast pipe 4 is connected with air blast 3, and air blast 3 is connected with flue 2; Described coke bin 1 top bulkhead is provided with 5 feed bin inlet scoops 6,5 feed bin inlet scoops 6 are all connected with discharge pipe 7, discharge pipe 7 is connected with cleaner 8 air inlets, and cleaner 8 air outlets are connected with air exhauster 9 air inlets, air exhauster 9 air outlets with enter hot-blast stove flue pipe 10 and be connected.
Wherein, flue 2 plays conduit effect; Make heat enter coke bin by 3 of air blasts; Blast pipe 4 plays conduit effect; 2 ~ 4 air inlets are set and play mean allocation incoming air area; The steam and the carbon monoxide effect that produce in coke heating process of drawing worked in 5 feed bin inlet scoops; Discharge pipe 7 also plays conduit effect; Cleaner 8 is for collecting coke blacking; Air exhauster 9 is exhausting power; Enter hot-blast stove flue pipe 10 and also play conduit effect.
