Executing in example, described high temperature vapour source apparatus is as it is shown in figure 1, be set to forward and backward high temperature vapour source dress
Put 3A, 3B.Being passed through the vapour source of high temperature air intake is the mixed of steam or steam and other gases
Close vapour, after vapour source is first premenstrual high temperature vapour source apparatus 3A heating, then through reheating equipment (after
High temperature vapour source apparatus 3B) heating after gas.The steam that front high temperature vapour source apparatus 3A produces
Preferably low-pressure superheated steam, it is also possible to be the tail steam with heat energy；Described mixed steam
In steam rates the highest more good, other gas should be the vapour that the coal of processing will not be caused to catch fire
Body.Described high temperature vapour source apparatus can be steam superheater, thermal medium boiler or heat exchanger etc.
Other can be to the equipment of gas heating.
During work, coal 7 to be processed is sent to be located at the charging aperture 2 at tank body top, to be processed
Coal 7 can rely on gravity fall, it is also possible to enter vertical tank according to the charging gear that sets
In body 1.The cross-sectional area of described charging aperture 2 should be less than the cross-sectional area of tank body 1, and
Described charging aperture 2 has certain length connection tank interior, in the present embodiment, described
Charging aperture 2 has certain length and extends into tank interior, and meeting the stock column of coal when filling material can hinder
Only substantial amounts of air can enter from charging aperture 2.
It is provided with airlock 6 in charging aperture 2, after coal 7 enters tank body 1, is being positioned on tank body
The preheating section 1A in portion is entered by the tail vapour of the steam risen in the middle part of tank body or bottom or mixed steam
Row preheating, absorbs steam simultaneously and condensed water self is the most heating up, and the tail produced further
The most one or more tail vapor outlet 4 arranged from tank body top of vapour discharges tank body.Pass through
The work of the air inducing equipment 8 that tail vapor outlet 4 connects, overall (except air intake 3 in making tank body 1
Can be malleation can also be that negative pressure is outer) be in subnormal ambient.Described tail vapor outlet 4 connects
Described high temperature air intake 3.The tail vapour drawn from air inducing equipment 8 can be partly as mixed steam
Composition from high temperature air intake 3 enter reuse.Small part tail vapour or condensed water are with coal
Grain is descending.
This utility model is also provided with one at the middle part of the preheating section 1A of tank body 1 or bottom increase
Or multiple air intlets 9.Air intlet 9 connects gas dispersion apparatus, in order to gas is equal
Spread evenly.Air enters tank interior from air intlet 9, from multiple tail vapour at tank body top
During outlet 4 extraction, substantial amounts of condensed water and low can be entrained with in coal particle surface and tank body
Temperature tail vapour, reduces condensed water descending by Repeat-heating with coal particle, reduces the total power consumption being dried.
Being passed through the vapour source of high temperature air intake 3 is steam or steam and the mixed steam of other gas.Mixed
Close steam proportion in vapour the highest more good, in described mixed steam other gases can be containing
The tail vapour with heat energy extracted out from tail vapor outlet 4 as above, can be containing air,
Can also be containing insoluble or be insoluble in the oil vapour of water, or containing the volatile gas of room temperature etc.
Other favourable gas.Described high temperature air intake 3 connects gas dispersal device, in order to steam
Or mixed steam spreads equably.Bringing-up section 1B is continued traveling downwardly by the coal of tank body preheating section 1A,
The mixed steam of the steam entered by high temperature air intake 3 or steam and other gas delays from top
The most descending coal carries out the temperature of the mixed steam of heating, drying, steam or steam and other gases
(steam is limited less than 180 DEG C of drying capacities, and drying rate is slow, and steam consumes to should be higher than that 180 DEG C
Amount is big), and the vapour amount of the mixed steam of required steam or steam and other gases should be able to make this
The temperature of the coal of tank body bringing-up section 1B is increased to 105 DEG C-180 DEG C (products during less than 105 DEG C
Product coal easily relapses the moisture content in air, and the fugitive constituent in product coal during higher than 180 DEG C is easy
Effusion).In drying course, the mixed steam own temperature of steam or steam and other gas reduces
Or partial condensation, the steam major part being evaporated in uncooled tail vapour and coal rises, with upper
The coal in face and air carry out further heat exchange, and small part is descending with coal particle.
As it has been described above, this utility model add in the mixed steam being passed through high temperature air intake insoluble or
Being insoluble in the oil vapour of water, be because subnormal ambient and run, oil vapour is easily absorbed by coal particle,
The water resistance of readymade coal can be strengthened.
As it has been described above, this utility model add in the mixed steam being passed through high temperature air intake ethanol,
Volatile gas under the room temperature such as industrial alcohol, can make coal let slip in heating process and finished product heap
Journey can be dehydrated further.
The coal of heated section of 1B heating, drying continues traveling downwardly, and self evaporates moisture content further,
Self gradually lowers the temperature simultaneously, is finally discharged by the discharging opening 5 of tank base.The horizontal stroke of discharging opening 5
Sectional area is less than the cross-sectional area of tank body 1, and described discharging opening 5 has certain length and stretches out
Outside tank body 1, substantial amounts of air can be stoped to enter tank body from discharging opening 5 meeting the stock column of coal.
Discharging opening 5 is provided with airlock 6, and the coal discharging tank body can be cold through natural cooling or further pressure
But (self the meeting a part of moisture content of re-evaporation simultaneously), it is finished product.
This utility model by changing input and output material speed, or can change and preheat, heat, cool down
The shape of each stage tank body and volume control the coal time of staying at each position of tank body, thus control
The effect that system is dried, it is also possible to the steam fed by change or steam and the mixing of other gas
Temperature and the vapour amount of vapour change dry effect.
Described above illustrate and describes preferred embodiment of the present utility model, as it was previously stated, should
When understanding that this utility model is not limited to form disclosed herein, it is not to be taken as other
The eliminating of embodiment, and can be used for other combinations various, amendment and environment, and can be herein
In described utility model contemplated scope, entered by above-mentioned teaching or the technology of association area or knowledge
Row is changed.And the change that those skilled in the art are carried out and change are without departing from spirit of the present utility model
And scope, the most all should be in the protection domain of this utility model claims.
