Analysis is energy-saving significant for rotary kiln.Original technique can only be according to combustion gas the data such as general calorific value adjust back
Rotary kiln wind coal proportion, degree of regulation is low, causes rotary kiln metallurgy model entry condition value deviation very big, seriously affects rotary kiln roasting
The precision of firing technique Combustion System.
Invention content
The purpose of the present invention aims to solve the problem that the online real time collecting of lime calcining process fuel gases calorific value parameter, is roasted for rotary kiln
Observing and controlling basis is established in accurately controlling for firing technique combustion model.
For this purpose, the technical solution that the present invention is taken is：
A kind of integrated acquisition of rotary kiln fuel gases calorific value and on-line analysis, specific method and step are：
(1) apply PCI-6034E high--speed multi--channel data acquisition boards, by fuel gas pipeline fuel gases calorific value sensor,
The non electrical quantity analog signal acquired in gas flow sensor, gaseous-pressure sensor detection unit is converted to digital signal, leads to
It crosses computer PCI bus agreement and communicates memory cache of the receiving terminal High Speed Transfer to host computer.
(2) application software establishes median filter, and to collected data cached progress on-line analysis, processing, removal is high
Frequency noise, low-frequency noise and data the disposal of gentle filter ensure collected fuel gases calorific value, flow, pressure and actual value deviation
Meet TT＆C system required precision.
(3) D-Link Industrial Ethernet is passed through after ICP/IP protocol is organized into groups by the digitized signal that is filtered
Duplex signaling module real-time Transmission is to data transmitter.
(4) rotary kiln combustion control system is equipped with ethernet data acceptance machine and data analysis software, real-time reception combustion
Gas calorific value, flow, pressure data and by data according to marshalling rule parsing；Data are sent into rotary kiln Combustion System system after parsing
System participates in Combustion System and man-machine interface real time monitoring.
Beneficial effects of the present invention are：
1, the present invention provides for on-line uninterruption, real-time acquisition rotary kiln combustion gas thermal parameter under rotary kiln working condition
Important means accurately control for lime roasting technique combustion model and have established data basis.
2, system man-machine interface is friendly, and operation is succinct, and roasting industrial processes system for iron and steel enterprise's lime provides essence
True entry condition is laid a solid foundation for high-level, high quality lime production.
3, the acquisition in real time of steel mill's rotary kiln fuel gases calorific value, flow, pressure parameter and online high speed analysis and transmission can be achieved,
Rotary kiln combustion control system precision is substantially improved, prevents lime burning and the generation of raw burn.
Specific implementation mode
The present invention makes full use of existing equipment, to reduce implementation cost, using original sensing system using special hard
Part board independent research data collecting system and filtering algorithm software building high rate data communication system, online real time collecting revolution
Kiln fuel gases calorific value, pressure, flow thermal parameter are simultaneously converted to digitized signal, and digitized signal is after line filtering and analyzing processing
By Industrial Ethernet remote transmission, the high speed acquisition and data transmission of rotary kiln fuel gases calorific value parameter are realized.

The non electrical quantity analog signal acquired in mass-air-flow sensor, gaseous-pressure sensor detection unit is converted to digital signal, passes through
The memory cache of computer PCI bus agreement and communication receiving terminal High Speed Transfer to host computer.
2, application software establishes median filter, and to collected data cached carry out on-line analysis, processing removes high frequency
Noise, low-frequency noise and data the disposal of gentle filter ensure that collected fuel gases calorific value, flow, pressure and actual value deviation are full
Sufficient TT＆C system required precision.
3, by the digitized signal that is filtered after ICP/IP protocol is organized into groups, it is double to pass through D-Link Industrial Ethernet
Work communication module real-time Transmission is to data transmitter.
4, rotary kiln combustion control system is equipped with ethernet data acceptance machine and data analysis software, real-time reception combustion gas
Calorific value, flow, pressure data and by data according to marshalling rule parsing；Data are sent into rotary kiln combustion control system after parsing,
Participate in Combustion System and man-machine interface real time monitoring.
