Abstract
The utility model relates to drying systems, in particular to devices for drying materials with reduction kiln fume, and more specifically discloses a device for pretreating and drying laterite-nickel ore with the reduction kiln fume. The device comprises a reduction kiln (1) and a drying machine (3). An air outlet of the reduction kiln (1) is connected with an air inlet of the drying machine (3) through a pipeline. An induced draft fan (2) is disposed on the pipeline. The device solves the problem that the existing drying devices in nickel production consume a large amount of power and waste energy. The device has the advantages that heat of the reduction kiln is utilized to dry raw materials, energy is saved, a case of the drying machine is driven to rotate through a motor, and fine drying effects and high drying efficiency are achieved.
Description
Technical field
The utility model relates to drying system, is specifically related to utilize the reduction kiln flue gas that raw material is carried out dry equipment.
Background technology
Oven dry refers to remove by some way the technical process that solvent keeps solids content.Typically refer to the process that hot-air evaporates moisture in the material and take away that passes into.
Drying plant refers to by certain technological means, the combination of the moisture on drying objects surface or a series of plant equipment of other liquid.Popular drying technology mainly is hot-air seasoning at present.They have their own characteristics each, and are widely used in the oven dry of various raw materials and food.
The nickel need of production is used reduction kiln, and the flue-gas temperature that reduction kiln is discharged is very high.Produce raw materials used with nickel and be lateritic nickel ore, need aborning lateritic nickel ore is carried out drying, existing drying equipment need to consume a large amount of electric power, wastes energy.
The utility model content
The utility model provides the device of the dry lateritic nickel ore of a kind of reduction kiln flue gas preliminary treatment, and the utility model has solved nickel and produced in the institute, adopts existing drying equipment need to consume a large amount of electric power, the problem that wastes energy.
For addressing the above problem, the utility model adopts following technical scheme: the device of the dry lateritic nickel ore of a kind of reduction kiln flue gas preliminary treatment comprises reduction kiln 1 and drying machine 3; The air outlet of described reduction kiln 1 connects the air inlet of drying machine 3 by pipeline, be provided with air-introduced machine 2 at pipeline.
The air outlet of drying machine 3 is by pipeline connection cyclone separator 4, and cyclone separator 4 is by pipeline connection sack cleaner 5, and sack cleaner 5 connects exhaust air-introduced machine 6 by pipeline, and exhaust air-introduced machine 6 connects chimney 7.
The shell of described drying machine 3 is Horizontal cylindrical structures, and enclosure is set with gear ring 3-1, is provided with motor 3-3 below shell, in the motor 3-3 rotating shaft gear 3-2 is installed, gear 3-2 and gear ring 3-1 engagement.
Advantage of the present utility model: utilize the heat dried feed of reduction kiln, save the energy; The drying machine housing rotates by driven by motor, and drying effect is good, and efficient is high.

The technological process of production: reduction kiln flue gas---drying machine---cyclone separator---sack cleaner----air-introduced machine.
1. raw material condition is dried: state: shape, granular size;
First moisture content: butt moisture content=
Wet basis moisture content=
Just moisture content refers to wet basis moisture content generally speaking.
2. drying system: Air Dried System: particle is less or moisture content is less; The revolving cylinder drying system: the large or moisture content of particle is large (more than 30%);
3. EAT situation: pneumatic conveying drying: moisture content 30%-40% or more than, temperature can be controlled at more than 180 ℃; Revolving cylinder is dry: (30%-40% or more than) temperature control was more than 200 ℃ when moisture content was higher; Low moisture content class temperature control is below 160 ℃;
4. leaving air temp: whole moisture content is more than 10%, and the revolving cylinder drying system is controlled at 60 ℃, and Air Dried System is controlled at 80 ℃; Whole moisture content is at 5% time, and the revolving cylinder drying system is controlled at 70 ℃, and Air Dried System is controlled at 90 ℃.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
