Description
Technical field
The utility model relates to coke manufacturing equipment, specifically a kind of online drying system of coke.
Background technique
Coke is that one of the important source material that blast furnace ironmaking uses due to being influenced by environmental factors such as rainwater causes coke
There are a large amount of moisture in stacking process for charcoal, while a large amount of aqueous coke enter in blast-furnace coke feed bin.Coke feed bin includes
Water coke enters blast-furnace roasting after vibrating screen sieves.But the coke adhered on coke is influenced by moisture in screening process
Powder sticks on sieve and coke, and screening effect is bad, meanwhile, feeding density charcoal excess moisture and attachment coke powder increase, and will cause furnace
Interior temperature reduces, and fuel ratio increases, and increases ton iron production cost.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of online drying systems of coke, discharge fume using outside hot-blast stove
Coke in gas residual heat drying coke feed bin.
The utility model solve its technical problem the technical solution adopted is that:
A kind of online drying system of coke, including hot-blast stove, heat exchanger, air-introduced machine empty chimney, coke feed bin, heat exchange
Device includes heat exchanger flue gas disposed in parallel end and heat exchanger air end, and the side at heat exchanger flue gas end passes through flue and heat
The other side of wind furnace connection, heat exchanger flue gas end is connected to by exhaust piping with waste stack；The side of heat exchanger air end is logical
Supercooled air pipeline is connected to air-introduced machine, and the other side of heat exchanger air end is connected to one end of the first hot-air duct, and first
The other end of hot-air duct is connected to the head end of the second hot-air duct in coke feed bin, the end of the second hot-air duct
It is connected to emptying chimney.
The utility model by adopting the above technical scheme, compared with prior art, beneficial effect is:
Solve the problems, such as that coke moisture is high, coke moisture content reduces 1% ~ 2%, improves screening efficiency, stablizes in furnace
Temperature reduces ton iron production cost.
Further, the prioritization scheme of the utility model is:
Flue is oppositely arranged with cold-air duct.
Exhaust piping is oppositely arranged with the first hot-air duct.
The end of first hot-air duct is equipped with regulating valve.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
In figure: hot-blast stove 1；Flue 2；Heat exchanger 3；Heat exchanger flue gas end 4；Exhaust piping 5；Waste stack 6；Air inducing
Machine 7；Cold-air duct 8；Heat exchanger air end 9；First hot-air duct 10；Empty chimney 11；Coke feed bin 12；Regulating valve
13；Second hot-air duct 14.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Refering to fig. 1, the online drying system of a kind of coke by hot-blast stove 1, flue 2, heat exchanger 3, exhaust piping 5, is given up
Gas chimney 6, air-introduced machine 7, cold-air duct 8, the first hot-air duct 10, emptying chimney 11, coke feed bin 12,13 and of regulating valve
Second hot-air duct 14 is constituted.
Heat exchanger 3 is made of heat exchanger flue gas end 4 and heat exchanger air end 9, heat exchanger flue gas end 4 and heat exchanger air end
About 9 are arranged in parallel, and the side at hot device flue gas end 4 is connected to by flue 2 with the bottom of hot-blast stove 1, hot device flue gas end 4
The other side is connected to by exhaust piping 5 with the bottom of waste stack 6.Realize the residual temperature flue gas of the discharge of hot-blast stove 1 via fume pipe
Road 2, heat exchanger flue gas end 4, exhaust piping 5,6 outlet of waste stack.
The side of heat exchanger air end 9 is connected to by cold-air duct 8 with the air outlet of air-introduced machine 7, heat exchanger air end 9
The other side be connected to one end of the first hot-air duct 10, in the other end of the first hot-air duct 10 and coke feed bin 12
The head end of second hot-air duct 14 is connected to, and the end of the second hot-air duct 14 is connected to emptying chimney 11, the first hot-air
The end of pipeline 10 is equipped with regulating valve 13.
Cold air is introduced after cold-air duct 8 via air-introduced machine 7 and is being changed into heat exchanger air end 9, cold air and flue gas
It exchanges heat in hot device 3, the hot-air after heat exchange enters the second heat sky in coke feed bin 12 by the first hot-air duct 10
Feed channel 14 exchanges heat, and realizes coke moisture drying, and the hot-air after heat exchange is discharged by emptying chimney 11.
Flue 2 is oppositely arranged with cold-air duct 8, and exhaust piping 5 is oppositely arranged with the first hot-air duct 10.It is real
The flow direction of existing cold air and flue gas is on the contrary, increase heat transfer effect.
The present embodiment controls hot air flowrate using regulating valve 13, guarantees that 12 coke of coke feed bin is normally dried, prevents heat
Air mass flow is excessive to cause drying is excessive the generation of coke fragmentation phenomenon occur.
Due to, containing a large amount of remaining coal gas, existing so that directly drying coke using hot-blast stove fume in hot-blast stove fume
Security risk, so the utility model carries out flue gas and air heat-exchange using heat exchanger, so that into the hot-air of coke feed bin
Without excessive gas composition, guarantees the safety of production district, eliminate safe hidden trouble.
The above is only the preferred feasible embodiment of the utility model, not thereby limits to the power of the utility model
Sharp range, it is all with equivalence changes made by the utility model specification and its accompanying drawing content, it is both contained in right of the invention
Within the scope of.
