Description
Technical field
The utility model relates to a kind of temp measuring system of Industrial Stoves furnace high-temperature, especially a kind of cement rotary kiln stove temp measuring system.
Background technology
In New Type Dry-process Cement Production, in the Real-Time Monitoring cement rotary kiln, the calcining situation becomes and becomes more and more important at present.This is because the calcining situation in cement rotary kiln is directly connected to Yield and quality, original fuel consumption and the cost of cement clinker.Not only fuel consumption is very large for too high calcining heat and excessive thermal oscillation, even likely kiln lining is caused damage, and when serious, will injure kiln shell.The too low meeting of calcining heat has a strong impact on the quality of cement clinker.
The calcining situation is normally monitored the trunk surface temperature, is detected flame temperature in kiln hood and the means such as state of flame and grog in kiln of observing come aspect to understand the information of cement rotary kiln calcining in cement rotary kiln.Domestic most new type dry kiln all has been equipped with kiln shell surface temperature monitoring system, kiln hood flame TV monitoring system and colorimetric pyrometer at present.Because these equipment all can only reflect in the cement rotary kiln calcination process local message in different phase, and these equipment are unfavorable for that mostly in separate workbench operating personnel do whole understanding and judgement to whole calcination process information.
The utility model content
The utility model is high for temperature in cement rotary kiln stove stove, and kiln body rotation is difficult for wiring, measures the characteristics such as difficulty, and especial manufacture goes out a kind of being applicable to temperature in cement rotary kiln stove stove is carried out to continuous measuring device, specifically is achieved through the following technical solutions:
A kind of cement rotary kiln stove temp measuring system is characterized in that: comprise some CCD thermal-flame detectors 1 and background computer 3, described CCD thermal-flame detector 1 is connected with background computer 3 by optical fiber or cable; Described CCD thermal-flame detector 1 all is arranged on kiln hood lid circumferential side wall, and it is concordant with furnace wall that the mirror pipe is goed deep into to furnace.
Further, described system also comprises Video segmentation device and video frequency collection card 2, described Video segmentation device and video frequency collection card 2 are arranged between CCD thermal-flame detector 1 and background computer 3, connect by logical circuit, after the synthetic piece image of several flame radiation images that CCD thermal-flame detector 1 is collected, be transferred to background computer 3.
Further, 1 at least 3 of described CCD thermal-flame detector, and be evenly distributed on kiln hood lid circumferential side wall.
The beneficial effects of the utility model are: 1) can show more accurately temperature in stove, for commercial production provides guidance; 2) be convenient to provide raw data to cement rotary kiln stove and whole cement producting automation control system.
The accompanying drawing explanation
Fig. 1 is the utility model one-piece construction schematic diagram;
Fig. 2 is CCD thermal-flame detector distribution schematic diagram.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises some CCD thermal-flame detectors 1 and background computer 3, and described CCD thermal-flame detector 1 is connected with background computer 3 by optical fiber or cable.Described CCD thermal-flame detector 1 all is arranged on kiln hood lid circumferential side wall, and it is concordant with furnace wall that the mirror pipe is goed deep into to furnace.
Native system also comprises Video segmentation device and video frequency collection card 2, as Fig. 1, described Video segmentation device and video frequency collection card 2 are arranged between CCD thermal-flame detector 1 and background computer 3, connect by logical circuit, after the synthetic piece image of several flame radiation images that CCD thermal-flame detector 1 is collected, be transferred to background computer 3.
As preferred version, the utility model adopts 3 CCD thermal-flame detectors, as shown in Figure 2,3 CCD thermal-flame detectors 1 is evenly arranged on the sidewall of kiln hood lid, the investigative range of every detector is 80 °, guarantees to cover from different perspectives picture in stove comprehensively.By CCD thermal-flame detector 1, utilize heat radiation that tens meters long flames are presented fully, know that the temperature field in stove distributes, then the video and the picture signal that collect are arrived to background computer 33 places by optical fiber or cable transmission, carry out the data processing.
Native system is when carrying out the data processing, adopt special-purpose reconstruction algorithm software to calculate in real time the burner hearth three-dimensional temperature field, dynamically show three megadyne temperature degree distribution situations in stove, and further provide furnace tube wall heterogeneous radiation heat flux distribution, volume heat load and distribute, pass through analyzing and diagnosing, provide nozzles fuel quantity and air quantity the tutorial message such as to optimize and revise, be convenient to the burner hearth monitor staff and better carry out in combustion analysis diagnosis, burner adjustment, stove Temperature Distribution control etc.Specifically three-dimensional burner hearth system is considered as to a gray system formed by gray solid wall and the grey medium that surrounds; The employing grid is divided, and area of space is divided into to M unit, and the wall zone is divided into N unit; Amount to I unit.Obtain radiation information in stove with CCD, J pixel unit of each CCD target surface; CCD is placed in furnace wall, requires its field angle to cover as much as possible the burner hearth zone.
The radiant image model has been set up the quantitative relationship between three-dimensional Temperature Distribution in flame radiation image and stove; Establish the radiant image new model again and set up the quantitative relationship between three-dimensional Temperature Distribution in flame two-dimension temperature image and stove, the reference point temperature uses the colourimetry based on coloured image R, G, B three primary colours to calculate; Finally utilize numerous computing formula and data analysis to calculate burner hearth internal combustion temperature field.
The content of technique scheme is only disclosing that preferred embodiment of the present utility model is done, and can not be used for limiting the utility model, and the content that protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.Anyly have the knack of the art person, within not breaking away from spirit and scope of the present utility model, various variations of doing or be equal to replacement, all should belong to protection domain of the present utility model.
