Algorithm obtains temperature data in turn.Conversion module 11 be include communicating circuit, power circuit, cpu circuit, memory, interface protect
The electronic assembly part of protection circuit etc., cpu circuit storage inside have special-purpose software to handle data.
Traditional online photoelectric pyrometer is made of three parts: optical lens assembly, optical fiber and photoelectric conversion device.Its
In, optical lens assembly is made of quartz glass and stainless steel, has resistance to certain high temperature feature.For the flue dust for preventing flue
Pollution, avoids glass from melting, and air guide hole is equipped with before camera lens, by being continuously sent into clean air or nitrogen to air guide hole, forms phase
To the micro-positive pressure of flue, flue dust is prevented to enter in optical system.
The optical signal that optical lens assembly is collected is sent to photoelectric conversion device by optical fiber.Optical fiber is protected with metal hose
Shield is placed in along the channel steel of charger rail arrangement, thermal insulation material is equipped in channel steel, prevents flame from directly scorching.
Photoelectric conversion device send control system after optical signal is converted to temperature signal.
For the system by optical fiber by conduct radiation to instrument system, instrument system may be mounted at the lower environment of temperature,
Optical system and optical fiber can bear 200 degree or so of environment temperature, to realize on-line continuous measurement.
Major defect existing for traditional online photoelectric pyrometer is as follows:
1, optical fiber
At high cost, optical fiber home products resistant to high temperature is also immature, import it is expensive.
Manufacture is complicated, and light-entering surface is required without any pollution out, and plane precision reaches certain grade, otherwise causes to pass
It is inconsistent to lead attenuation rate.But fiber lengths are customized after needing scene to determine, it is necessary to in-site installation, pollution problem can not solve,
Fiber lengths are inconsistent, and turning radius difference causes light attenuation coefficient uncertain, cause final accuracy decline.
Optical fiber is crisp easily broken, current installation protection scheme, and normal working life is 2-3, there was only professional people after damage
Member repairs replacement, and user can not voluntarily be handled.
2, measuring system cannot exclude visible light interference
Reading fluctuation is very big (20-30 degree) after photoelectric conversion, can only be obtained by the method that software carries out data processing
Stablize output, data reliability is not high.
3, technology innovation is slow
System transmits signal using 2 line current systems, needs in control room two times transfer to be digital quantity, causes system multiple
Miscellaneous, investment is big, difficult in maintenance.
4, installation is inconvenient
Flue temperature-measuring port is located at furnace roof, and bell temperature has 300 or so, and coal vehicle is constantly walked, and flue dust is very big, furnace roof temperature
It spends very high (degree of summer more than 70), the available action time is extremely short, the optical fiber erector for being needed finely to install under such conditions
Make, difficulty is very big.
Compared with the online photoelectric pyrometer of the above tradition, the present invention uses unitary design, conversion module 11 and optical frames
Head assembly 9 is set altogether in a shell, is connected without optical fiber, is taken full advantage of two functions of instrument air or nitrogen, and blow
Sweep function, refrigerating function.And modular design, optical lens assembly 9 and main body 2, conversion module 11 and main body 2 use bullet
Property part connection, dismounting can be completed by plug when replacement.
2 interior design of main body has air-guiding wall, and design has temperature-difference power generation module installation site, and air-flow is entered by gas-tpe fitting
Afterwards, electricity generation module is purged first, improves thermo-electric generation transfer efficiency.
Outer surface is painted with insulating moulding coating, stops solar radiation and the baking of boiler face high fever, reduces purging cooling gas loss,
It is unlikely to cause component thermal to damage at once when accidentally dying simultaneously.
In use, usual fire path temperature test point is the burner block surface temperature of coking furnace shaft, it is different according to coke oven size,
Temperature measuring point is at a distance from placement temperature measuring equipment in 6-12 meters of ranges, and farther out, use is non-contacting for thermometer hole and burner block distance
Bell 17 is placed in progress temperature measurer work on thermometer hole by temperature measuring equipment.
Final temperature data can be used a variety of transmission methods and be transferred to control system:
1, using RS485 type mainboard, realize that RS485 interface and host computer communicate, it is a pair of to upload data one for observed temperature
It answers, matched PC machine user adjusts software and can this pyrometer be configured and be calibrated, and reads measured angle value；Application No. is
2017216960594 patent names " RS485 type photoelectric pyrometer " disclose corresponding technical solution.
2, it using the mainboard of 2 line 4-20mA electric current ring interfaces, is communicated with current system and host computer, size of current and temperature
Degree corresponds, and current signal can be converted to temperature value by fastener by host computer.
3, using wireless signal transmission mainboard, using the LORA frequency-extending transmissioning module or 2.4gHz carrier wave of 433mHz carrier wave
Zigbee module realize data transmission.
Working principle of the present invention is as follows:
Object with certain temperature is all ceaselessly issuing radiation energy, the size of object radiation energy to surrounding space
There is relationship with its surface temperature, its surface temperature can accurately be measured by the measurement to object itself radiation energy, this
It is exactly objective base based on radiation temperature measurement.Intensity distribution of the object to surrounding space radiation energy are as follows:
In formula: C --- the light velocity
H --- Planck's constant
K --- Bohr grows graceful constant
T --- absolute temperature
λ --- optical wavelength
ε --- coefficient of blackness (emissivity)
The amount of radiation of all actual objects remove with the temperature of radiation wavelength and object mutually outside the Pass, also with the material kind of object
The factors such as class, surface state and environmental condition are related, this feature is generally described with emissivity.Emissivity indicates actual object
Heat radiation and black body radiation degree of closeness, codomain be [0,1].According to radiation law, object materials emissivity is obtained, just
The radiation characteristic of the object can be calculated.
The present invention is a kind of online pyrometer, and integrated design has and dismounts easy to maintain, plug and play, operation dimension
The low feature of shield expense.
It can be that other connectors are applied in calcining kiln by replacement bell the present invention provides coke oven embodiment is directed to,
Implement temperature measurement in other fields such as calcining kiln.
The preferred embodiment for the present invention is explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be without departing from the purpose of the present invention
It makes a variety of changes.
Many other changes and remodeling can be made by not departing from the spirit and scope of the present invention.It should be appreciated that the present invention is not
