With reference to shown in Fig. 1 and 2, wherein, Fig. 1 is embodied for mixed coal drying and preheating device provided by the utility model
The structural representation of example, Fig. 2 is the cross section structure diagram of mixed coal drying and preheating device shown in Fig. 1.
Mixed coal drying and preheating device includes casing 1 and dividing plate 5；Wherein, casing 1 is divided into air flue 1g and coal by dividing plate 5
Road 1c, air flue 1g have air inlet and exhaust outlet, and breeching 1c has coal feed point and coal outlet, and air inlet is used to connect with coke oven,
Imported with the hot waste gas for producing coke oven combustion in air flue 1g, and switch valve 2 is provided with coal outlet, to control coal outlet to open
Or closure.
In detail, air inlet is imported the hot waste gas in air flue 1g by air inlet pipe 3, and exhaust outlet will by blast pipe 4
Low temperature waste gas after heat exchange processing is exported to outside air flue 1g.
The drying principles of this mixed coal drying and preheating device are：
Coal outlet is first closed, then mixed coal is filled into breeching 1c, the heat that coke oven combustion generation is passed through in air flue 1g is given up
Gas, both mixed coal and hot waste gas carry out indirect heat exchange, heat of the mixed coal because absorbing hot waste gas, the reduction of its water content, temperature
Degree rise, and hot waste gas becomes after cryogenic gas through being discharged by exhaust outlet because of heat release；Finally, coal outlet is opened by drying and preheating
Mixed coal after reason, which is exported to coke furnace carbonization chamber, carries out coking.
Obviously, this mixed coal drying and preheating device makes full use of coke oven to produce the waste heat of waste gas, and mixed coal is done
Dry the pre-heat treatment, reduces the wasting of resources and environmental pollution caused by hot waste gas is directly discharged.
With continued reference to shown in Fig. 2, mixed coal drying and preheating device includes multiple air flue 1g and multiple breeching 1c, and air flue 1g
Set with breeching 1c spacing side by side.
It will be appreciated that being arranged such can make the heat transfer process of both mixed coal and hot waste gas more efficient.Certainly, meeting
On the basis of both mixed coal and hot waste gas heat exchange function, processing and assembly technology requirement, those skilled in the art also can basis
The practical structures of casing 1 adjust air flue 1g and breeching 1c quantity.
In order to improve the heat exchange efficiency of mixed coal drying and preheating device, air flue 1g is one more than breeching 1c, and along air flue 1g
Be air flue 1g with the breeching 1c initiating terminals and clearing end that direction is arranged side by side, it is understood that for air flue 1g one more than breeching 1c
It is individual.
For example, air flue 1g and breeching 1c arrangement mode can be：Air flue 1g- breeching 1c- air flue 1g, can also
For：Air flue 1g- breeching 1c- air flue 1g- breeching 1c- air flues 1g.It is appreciated that specific arrangement mode depends on air flue 1g and breeching
1c particular number.
In this way, each breeching 1c is enclosed and formed by casing 1 and two dividing plates 5 so that mixed coal can in a breeching 1c
Heat exchange is carried out with hot waste gas in two air flue 1g simultaneously, can further strengthen the heat exchange effect of mixed coal drying and preheating device
Rate.
In addition, the heat exchange efficiency in order to further improve mixed coal drying and preheating device, dividing plate 5 be preferably have compared with
The metal partion (metp) of high thermal conductivity.
As it was previously stated, switch valve 2 is provided with coal outlet, to control coal outlet closure or openness.In order to control to be manufactured into
Sheet and operation difficulty, the preferred electric rotating plate valve of switch valve 2 or sluice valve driven by manpower, electric rotating plate valve and sluice valve driven by manpower are except structure
It is simple to be easy to operation outer, the Flow-rate adjustment to coal outlet mixed coal, namely flap valve can be also realized according to the rotational angle of turnover panel
Control coal outlet is had concurrently to be turned on and off and the adjustable function of valve port opening.
Further, since self structure characteristic, flap valve can only control the closure or openness of a coal outlet, can also be simultaneously
Control being turned on and off for multiple coal outlets, that is to say, that a flap valve is the closure or openness that can control multiple coal outlets,
So as to which the manufacture of mixed coal drying and preheating device and maintenance cost are controlled in relatively low level.
Further, in order to avoid thermal loss in breeching 1c in heat exchanging process, casing 1 is also detachably connected with
Shielding cover is to block coal feed point.
During coalingging, shielding cover is removed, mixed coal is loaded by breeching 1c by coal feed point, after filling, then by shielding cover
Casing 1 is installed on to block coal feed point.
In detail, shielding cover and casing 1 can be connected conveniently in dismounting by deadweight or snap-in structure, and shielding cover can hide simultaneously
Keep off one or more coal feed points, those skilled in the art can be according to the concrete structure and the quantity set of coal feed point of casing 1.
In addition, in order to grasp mixed coal drying regime in breeching 1c in real time, to be follow-up mixed coal water content and temperature
The analysis of degree provides experimental data, and mixed coal drying and preheating device also includes being respectively arranged at breeching 1c middle parts, coal outlet and entered
Temperature-detecting device at coal mouthful, to detect the temperature of mixed coal at each test point in breeching 1c.
Detector unit is preferred to use thermocouple temperature sensor.It is appreciated that detecting mixed coal temperature work(meeting
On the basis of energy, processing and assembly technology requirement, those skilled in the art can use existing any detector unit.
Further, in order to more accurately grasp the heat exchanger effectiveness of mixed coal and hot waste gas, mixed coal drying and preheating
Device also includes being arranged at the detector unit at air flue 1g air inlet, to detect the temperature before hot waste gas heat exchange.
For the technique effect of those skilled in the art's more intuitive understanding mixed coal drying and preheating device, next with
One actual tests data is illustrated.
The heat transfer experiments of waste gas and mixed coal are carried out using above-mentioned mixed coal drying and preheating device, heat transfer experiments use 5
(certainly, breeching 1c and air flue 1g particular number are not limited in the specific number selected in example by air flue 1g and 4 breeching 1c
Value).
Process of the test is as follows：The mixed coal that water content is 10% is filled in breeching 1c, by certain temperature, certain flow
Hot waste gas is imported in each air flue 1g through air inlet.
Result of the test is shown：Before heat exchange, the mean temperature of hot waste gas is three temperature detections in 600 DEG C or so, breeching 1c
The temperature of mixed coal is 20 DEG C at point, and three's temperature is close；After heat exchange, mixed coal at three temperature detecting points in breeching 1c
Mean temperature found at 200 DEG C or so, and by Industrial Analysis, be now substantially free of water in mixed coal.
It is appreciated that the mixed coal after being handled through drying and preheating enters the carbonization chamber of coke oven, the knot in carbonization chamber is shortened
The burnt time, the temperature of mixed coal moisture evaporation is reduced, and then improve the production efficiency of coke oven.
In addition, the utility model also provides a kind of coke furnace system, the coke furnace system includes combustion chamber, carbonization chamber and foregoing
