Implementation side is sent out
A kind of concentrated ilmenite drying system device, the utility model feature are to be connected with high temperature drying fluid bed 4 by the belt feeder 14 of weighing by interior hot-blast stove 1 with throwing machine 3; High temperature drying fluid bed 4 connects respectively sub-cooled fluid bed 5 and dry bagroom 7; Sub-cooled fluid bed 5 be connected bagroom 7 and be connected with finished product belt conveyor 13 respectively with the cooling bagroom 9 that arranges; Wherein:
Hot-blast stove 1 connects respectively gas tank 16, diesel fuel tank 17, and is connected with respectively air distribution blower fan 2 and combustion fan 15;
Sub-cooled fluid bed 5 is connected with cooling air blower 6; Dry bagroom 7 is connected with dry air-introduced machine 8; Cooling bagroom 9 is connected with cooling air-introduced machine 10.
The utility model adopts the high temperature drying fluid bed in the drying process link, the high-temperature pressurizing thermal air current that air inlet can be entered evenly distributes, simultaneously used under shed shape blast cap at air distribution plate, hot-air distributes to the uniform air-flow of the last formation of air distribution plate by the blowback of blast cap opening, can effectively prevent the channeling that material occurs because of the air-flow skewness in fluid mapper process, can prevent that material from piling up in fluid bed forms dead bed, the top expanding reach has reduced fluosolids and has gone out gas pressure, be easy to the particles settling that tail gas is carried secretly, reduce the live load of sack cleaner; Discharging opening is provided with adjustable for height cofferdam, can control Height of fluidized layer by regulating, thereby the control material is regulated the degree of drying of material in the time of staying of fluidisation area.
The utility model conveying device adopts high speed material casting belt as the wet feed conveying device, cooperates the dispersing device of high temperature drying fluid bed charging aperture, can smash the ilmenite powder that hardens, uniform distribution.
The utility model pressurized heat air adopts diesel oil and gas double fuel combustion system to realize switching heat supply.
The utility model ferrotianium fine ore drying device is comprised of 5 main subsystems:
1. feed control system
The native system device is the delivery rate that the wet ilmenite of control is supplied with drying equipment.The belt feeder 14 of weighing is supplied with wet stock with a controllable speed from feed hopper and is set by DCS to high temperature fluidized bed 4 these feed rate, and it is measured the delivery rate of the belt feeder 14 of weighing and controls the delivery rate of belt with variable speed drives.It should be noted that the control delivery rate is the key of operation drying equipment.
2. combustion system
The native system device is to do 16 with diesel oil 17 or coal gas to be a kind of fuel (at every turn only a kind of fuel source).This combustion system is being controlled the fuel type that uses, and (fuel type is based on company's situation, selected by the operator according to higher level's instruction), the air that a large amount of fuel and combustion-supporting air blast 15 provide burns fully by burner, obtain a large amount of high-temperature flue gas, thereby the large quantity of air that high-temperature flue gas and drying drum blower fan 2 provide abundant mixing in hot-blast stove obtains certain leaving air temp and the high-temperature flue gas of pressure.Hot-blast stove 1 links to each other with the equal air compartment of high temperature drying fluid bed 4 bottoms.Hot-air inlets by high temperature drying fluid bed 4 enters, and by the blast cap on the air distribution plate, oppositely is blown into the material that promotes to wet in the fluidisation section of high temperature drying fluid bed 4 and forms fluidized state.
3. drying and dust collecting system
Wet ilmenite is sent into high temperature fluidized bed 4 charging apertures by throwing machine 3, dispersing device by the charging aperture place, material is thrown in the fluid bed, and so that material on high temperature fluidized bed 4 air distribution plate, evenly distribute, thereby blow over high temperature fluidized bed 4 dried feed that wet feed material is arranged from the high-temperature flue gas of combustion system 1.The waste gas that air outlet from high temperature fluidized bed 4 is discharged contains a large amount of dust, must filter through super-dry sack cleaner 7 before entering atmosphere.The dust that has filtered gives off through screw(-type) feeder 11, then sends into finished product bin through product conveyor 13.Waste gas is extracted out by dry air-introduced machine 8.If high temperature fluidized bed exit gas temperature is too high, can mend air-valve so that cooling air flows into dry dust collecting system 7 by opening, prevent that dry sack cleaner 7 from burning out.
4. cooling dust collecting system
