Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown, a kind of can-type calcine furnace for automatically controlling fire path temperature of the utility model, including 1 liang of every two batch can
Respectively there is one group of quirk in side, and combustion air channel 3 is equipped in the front wall 2 between two groups of quirks, and combustion air passes through combustion air channel
3, the first floor quirk 5 of 1 two sides quirk of batch can is entered by combustion air entrance, combustion air channel 3 reaches to be set on the part outside front wall 2
There is motorized adjustment butterfly valve 4, for adjusting the flow of combustion air, every group of quirk first floor fire is led in combustion air channel 3 out of front wall 2
5 entrance of road is equipped with differential pressure transmitter 6 in every group of 5 entrance of the quirk first floor, and motorized adjustment butterfly valve 4 and differential pressure transmitter 6 connect
Onto PLC controller 11, it is equipped with thermocouple 10 in the second layer quirk 7 of every group of quirk, layer 5 quirk 8 and the 8th layer of quirk 9,
Wall is connect with PLC controller 11 after thermocouple 10 stretches out, and volatilization subchannel 12 is equipped at the top of batch can 1, and volatilization subchannel 12 enters
Volatile matter Integration tunnel 13 at the top of every group of quirk, volatile matter Integration tunnel 13 lead to 5 entrance of first floor quirk.
The volatile matter Integration tunnel 13 is communicated to entrance above 5 entrance of first floor quirk, combustion air channel 3 from
Entrance is communicated to below 5 entrance of first floor quirk, volatile matter is mixed with air in 5 entrance of first floor quirk.
Described the 8th layer of quirk 9 of every group of quirk is connected to collection flue 14, and collection flue 14 is connected on main chimney flue 15,
Electronic flue gate valve 16 is equipped on main chimney flue 15, electronic flue gate valve 16 is connect with PLC controller 11.
Volatile matter in the utility model batch can 1 passes through the volatilization subchannel 12 of tank deck, into the volatile matter at the top of quirk
Integration tunnel 13 is mixed and burned at first floor quirk 5 with combustion air.Volatile matter and combustion air are by being mixed and burned in quirk, shape
At hot fume, the 8th layer of quirk 9 is moved to from first floor quirk 5 along quirk, the raw material in batch can 1 is calcined, petroleum coke is made
Raw material changes to after-smithing petroleum coke, and promotes the release of volatility of raw material point in batch can 1.First floor quirk 5 is equipped with differential pressure transmitter
6, measure the negative pressure of first floor quirk 5.Second layer quirk 7, layer 5 quirk 8 and the 8th layer of quirk 9 are equipped with thermocouple 10, measurement two
The temperature of layer, five layers, eight layers quirk.Thermal current in quirk enters collection flue 14 at eight layers of quirk 9, passes through collection flue
Into main chimney flue 15.Main chimney flue 15 is equipped with electronic flue gate valve 16, can control the negative of main chimney flue 15 by regulation gate valve aperture
Pressure, to adjust the overall negative pressure of quirk.
The utility model controls electronic flue gate valve by PLC controller 11, realizes to the automatic of 5 negative pressure of first floor quirk
Control；Motorized adjustment butterfly valve 4 is controlled, realizes the automatic control to the temperature of quirk.
In the case that whole can-type calcine furnace totality negative pressure is relatively low, electronic flue gate valve 16 is opened greatly, is improved overall negative
Pressure；Conversely, then electronic flue gate valve 16 is turned down.
The thermocouple of 8th layer of quirk 9 is primarily to detection avoids damage cigarette into the flue-gas temperature of collection flue 14
Road and follow-up equipment.When the 8th layer of quirk 9 when the temperature is excessively high, should reduce the aperture of motorized adjustment butterfly valve 4, reduce combustion air supply
Amount.
Under the premise of the thermocouple 10 of the 8th layer of quirk 9 is normothermic, 8 temperature of second layer quirk 7 and layer 5 quirk
It is higher and in rising trend, reduce the aperture of motorized adjustment butterfly valve 4, reduces the supply amount of combustion air；When second layer quirk 7
It is relatively low and on a declining curve with 10 temperature of thermocouple of layer 5 quirk 8, increase the aperture of motorized adjustment butterfly valve 4, increases combustion-supporting
Wind supply amount；When 10 temperature drift of thermocouple of second layer quirk 7, and it is in rising trend, five layers of fire path temperature are relatively low, discontinuity
Reduction, increase the aperture of motorized adjustment butterfly valve 4, the reduction of pulsed increases combustion air supply amount；When second layer quirk 7
10 temperature of thermocouple is relatively low, and on a declining curve, and five layers of fire path temperature are higher, and the increase of discontinuity reduces motorized adjustment butterfly valve 4
Aperture, the increase of pulsed reduces combustion air supply amount.
