Description
Technical field
The present invention relates to a kind of data monitoring device more particularly to a kind of electromagnetic induction applied in metallurgical coking field
The furnace tube temperature monitoring device of formula heating furnace.
Background technique
Currently, a kind of electromagnetic induction heating furnace, the heat of the heating furnace have been widely used in each metal metallurgy smelting enterprise
From several blocks of electromagnet arranged around burner hearth surrounding, heated body is spiral tubulose boiler tube in source.After energization, electromagnet is generated
Vortex makes spiral boiler tube generate heat, and commercial pitch is inputted in the case where conveying pumping action by electromagnetic induction heating furnace lower end, by heating furnace
Upper end outflow, to make asphalt temperature be heated to 370 DEG C by 330 DEG C, since the variation of furnace temperature can be directly related to commercial pitch
Product quality, it is therefore desirable to monitor the temperature of boiler tube.
The Temperature monitoring technology of electromagnetic induction heating furnace under the prior art is, in the input end pipe of electromagnetic induction heating furnace
Mouth and output end nozzle install input temp sensor and output temperature sensor, the boiler tube input of real-time monitoring heating furnace respectively
And two port temperatures of output, and temperature signal is transmitted to central control room, when temperature runaways, pass through adjusting
The controlling measurements temperature change such as flow, or take corresponding temperature adjustment measure.
However, this method of the prior art is only used for monitoring temperature when heating furnace operates normally, it is not able to satisfy and adds
Furnace tube temperature monitoring requirements-are so-called when hot stove boiler tube burns operation because of blocking uneven heating or to heating furnace implementation burns operation and is
After referring to electromagnetic induction heating furnace operation a period of time, blowing out coke cleaning operation.And the reason of generating this phenomenon, is, electromagnetic induction
In heating furnace operational process, the tube wall of boiler tube, which can be deposited, is formed by semisolid coke by the condensation reaction of pitch, and can day
The product moon is tired, gets deeper, so as to cause flow decline, yield decline, therefore will be by burning the unimpeded boiler tube of operation.
When burning operation, it is empty that the compression that pressure is 0.5MPa, flow is 30 cubes per hour is passed through in the input terminal of boiler tube
Gas, which will occur combustion reaction with the coke on deposition boiler tube tube wall, and generate 600 DEG C extremely in boiler tube regional area
800 DEG C of high temperature, at these elevated temperatures, the input temp sensor of input terminal nozzle and output end nozzle under the prior art and output
Temperature sensor can not play the role of due at all, lead to boiler tube performance for high progression and may be burnt.According to statistics, it presses
The electromagnetic induction heating furnace of the chemical company of type, burning operation, middle section region boiler tube is put down by burn-through accident frequent occurrence
Boiler tube is burnt every year up to 4 times, and every market value of the boiler tube of electromagnetic induction heating furnace is 140,000 yuan or so, boiler tube is once burnt only
Have and is disposed as steel scrap.In this way, not only coming into operation to heating furnace brings significant impact on schedule, but also bring biggish direct economy
Loss.
Other than the defect of above-mentioned input temp sensor and output temperature sensor itself, existing electromagnetic induction
Furnace temp monitoring technology is also limited by the structure of electromagnetic induction heating furnace, is sensed with the DS18B20 type dn junction temperature of sheet
For device, this general temperature sensor can only cover the port in input terminal boiler tube and output end boiler tube, and in heating furnace
Boiler tube between portion is adjacent is fully welded technique without any gap due to using, and the spacing between boiler tube outer ring and electromagnet is narrow
It is small, and what is filled in entire cylindrical type burner hearth is entirely flexible heat-insulating cotton, can not also be pacified between boiler tube inner ring and flexible heat-insulating cotton
Temperature measuring equipment is filled, therefore entirely boiler tube is other than the position of input terminal boiler tube and output end boiler tube without enough spaces for peace
Fill temperature measuring equipment.That is the temperature at other any positions in addition to boiler tube port can not be transmitted, and temperature original is low in burner hearth
In furnace tube temperature, it can not reflect boiler tube actual temperature by monitoring fire box temperature, i.e., heating furnace tube is because blocking uneven heating
Or when burning operation to heating furnace implementation, furnace tube temperature cannot monitor at all, so as to cause the frequent generation of accident.
In conclusion existing, there is an urgent need to a kind of novel electromagnetic heating induction furnace furnace tube temperature monitoring devices, in conjunction with electricity
Magnetic induction heating furnace single tube spiral formula feature, which provides one, can monitor other any spot temperatures in addition to heating furnace port
Device, to evade the boiler tube of heating furnace because locally burning risk caused by " honeycomb " effect.
