Description
Technical field
The utility model belongs to coal drying equipment technical field, and in particular to a kind of fluidized bed type brown coal drying device.
Background technology
Lignite, is the minimum pit coal of degree of coalification, a kind of brownish black between peat and pitch coal, lacklustre
Rudimentary coal.The features such as high volatile, high-moisture, low heat value, low ash smelting point cause lignite there are easy-weathering, easily naturally, being not easy to
Storage and transport, greatly reduce its utility value.
Fluid bed is among a large amount of solid particles are suspended in the fluid of movement, so that particle has some tables of fluid
Feature is seen, this solid contact condition of stream is known as fluidization of solid, i.e. fluid bed.Fluid bed is widely used in dry neck at present
Domain, can carry out the drying process of lignite with reference to the characteristics of fluid bed.Existing lignite fluidized bed drying system, structure are multiple
It is miscellaneous, it is troublesome in poeration, and fluidized drying is uneven, is not thorough, and amount of heat is wasted in fluidized bed drying processing procedure.
Utility model content
The purpose of this utility model is to improve a kind of multi-step, the fluidized bed type brown coal drying device of classification drying.
The utility model fluidized bed type brown coal drying device, including hothouse, air-heater and feed arrangement, feed arrangement are set
Put above hothouse, feed arrangement uses feeding screw, sets feed hopper above feeding screw, hothouse is divided into level-one
Hothouse and some secondary drying rooms, secondary drying room are located at below level-one hothouse, level-one hothouse and secondary drying room it
Between be equipped with vibrating screen, subregion sets the sieve aperture of different pore size size on vibrating screen, a corresponding secondary drying below each subregion
Room, vibrating screen are connected with vibrating motor, and two level air-heater and discharge port are equipped with below secondary drying room.
In use, lignite enters level-one hothouse by feed hopper after feeding screw, under the hot wind that air-heater provides
Fluidised form is formed, is dried, while vibrating motor drives shaker vibration, passes through by the dry lignite of primary on vibrating screen not
With the screening of the sieve aperture in aperture, into different secondary drying rooms, two level air-heater provides heat source and stream into secondary drying room
Dynamic medium, is further dried, by discharge hole for discharge after the completion of drying.In drying process, preliminarily dried in level-one hothouse
Afterwards, into secondary drying room, each indoor lignite particle diameter of secondary drying is different, it is desirable to provide hot blast rate it is also different, therefore
Separate drying, reduces energy consumption, in addition, dried lignite is classified also according to coal particle size, difference uses, and improves
The dry mass and quality of lignite.
Some moveable distributing devices are equipped with below the discharge nozzle of feeding screw, are uniformly distributed indoor brown into drying
Coal, improves drying efficiency.
Cloth slideway is equipped with the top of level-one hothouse, distributing device is placed in slideway, the external cloth motor of distributing device.
Compared with prior art, the utility model has the advantage of：The utility model fluidized bed type brown coal drying device, if
Two-stage hothouse is put, substep is dry, while lignite is classified drying according to particle size is different, while ensureing dry quality
Reduce energy consumption.

Side, is equipped with vibrating screen 6 between level-one hothouse 5 and secondary drying room 11, the sieve of subregion setting different pore size size on vibrating screen 6
Hole 12, each corresponding secondary drying room 11 in subregion lower section, vibrating screen 6 are connected with vibrating motor 7, the lower section of secondary drying room 11
It is equipped with two level air-heater 9 and discharge port 8.
Some moveable distributing devices 13 are equipped with below the discharge nozzle of feeding screw 2.
The top of level-one hothouse 5 is equipped with cloth slideway, and distributing device 13 is placed in slideway, the external cloth motor 3 of distributing device 13.
In conclusion the utility model fluidized bed type brown coal drying device, sets two-stage hothouse, substep is dry, at the same time
By lignite according to the different classification dryings of particle size, ensure to reduce energy consumption while dry quality.
The above is that the utility model is exemplarily described, it is clear that the utility model implements and from above-mentioned side
The limitation of formula, whether does any change in its shape or structure, if employ the utility model methodology and
The improvement for the various unsubstantialities that technical solution carries out, or not improved the design of the utility model and technical solution directly should
