Description

Blast funnace hot blast stove casing temperature monitoring system
Technical field
The utility model is related to a kind of steel plant's blast funnace hot blast stove casing temperature prison based on distributed optical fiber temperature measuring method Survey, specifically blast funnace hot blast stove casing temperature monitoring system.
Background technology
Blast-furnace production campaign is development mark and the important composition of contemporary ironmaking technology, and prolonging campaign is a system engineering, is related to To designing, multiple links such as build, operate, safeguarding by laying bricks or stones, wherein blast furnace cooling system it is effective using and control be to pass to furnace life Important factor.For timely, the accurate situation for holding blast furnace cooling board temperature and thermic load, rational cooling system is set up, And important parameter is provided for research blast furnace lining relevant information, to realize the stabilization of blast fumance and the longevity of stove, set up cold But plate thermic load monitoring system seems particularly significant.Real-time monitoring is carried out to hot-air stove shell temperature, directly reflects stove The situation of shell coldplate.
Traditional point sensor detection method be by measure resistance variations realize, just necessarily be formed one measurement Loop, and the only point of detection probe contact, can just be detected, therefore can not quickly monitor all cooling shells in real time Running situation, it is impossible to covering comprehensively, can not also be accurately positioned when finding cooling shell abnormal conditions.Traditional point sensor inspection The networking of survey method is complicated, and wiring installation difficulty is big, and later maintenance cost is high, is weak electric signal in itself, is highly prone to electromagnetic interference, Influence the stability of measurement performance.
The content of the invention
The utility model is intended to overcome the defect of prior art there is provided a kind of blast funnace hot blast stove casing temperature monitoring system, A large amount of point type temperature transducers can be replaced, covering comprehensively is realized, real-time to hot-air stove shell cooling plate temperature progress Monitoring, and hot-air stove shell cooling failure point can be accurately positioned.
In order to solve the above-mentioned technical problem, the utility model is realized in:
A kind of blast funnace hot blast stove casing temperature monitoring system, it is characterised in that:It includes temperature-measuring optical fiber, fiber cabling terminal Case, optical fiber temperature measurement host, signal acquiring processing system and host computer show system;The temperature-measuring optical fiber is layed in blast funnace hot blast stove Outside furnace shell coldplate, temperature-measuring optical fiber one end is connected by fiber cabling terminal box with blast funnace hot blast stove furnace shell, and temperature-measuring optical fiber is another End is connected with optical fiber temperature measurement host, and optical fiber temperature measurement host is that temperature-measuring optical fiber inputs light source and carries out data point to reflected light signal Analysis;The signal that optical fiber temperature measurement host is exported is acquired and handled and shows system by host computer by signal acquiring processing system Show.
Described blast funnace hot blast stove casing temperature monitoring system, it is characterised in that:The laying structure of the temperature-measuring optical fiber is Layer hinge Loose tube structure.
Described blast funnace hot blast stove casing temperature monitoring system, it is characterised in that:The temperature-measuring optical fiber is laid using looped network, Realize redundancy structure.
Described blast funnace hot blast stove casing temperature monitoring system, it is characterised in that:The optical fiber temperature measurement host and signal are adopted Collect processing system and use Modbus TCP communication interfaces.
The beneficial effects of the utility model are:Using distributed optical fiber temperature measurement technology, a large amount of point sensors can be replaced, Realize covering, monitoring that can be real-time to coldplate, and abnormal coldplate can be accurately positioned comprehensively;Avoid traditional scheme because Difficult wiring caused by monitoring point is excessive, the problem of networking workload is big, distributed temperature measuring optical fiber physical life length, reduction length Phase maintenance cost, and not by various electromagnetic interferences, the stability of guarantee temp measuring system.
The abundant monitoring software of distributed optical fiber temperature measurement main frame matching function, the thermic load of monitoring hot-blast stove can be presented in real time Space layout figure, shows the real time temperature currently gathered, and carries out characterization, shows the current amount of each loop alarming index Value;Coldplate abnormal alarm can be carried out, is required to set abnormal alarm value according to user, and monitored hot-blast stove can be cooled down Plate space sets different subregions by section, and the monitoring of various criterion is carried out to different positions;Settable multistage absolute temperature alarm With the alarm of the multistage temperature difference, or both combinations, wrong report is substantially eliminated;Alert locations can be accurately positioned, and record alarm number According to;Fibercuts alarm can be carried out, when fibercuts alarm occur and show fracture position, but because temperature-measuring optical fiber is used Looped network is laid out, even if generation optical fiber is graceful, can't influence the operation of temperature-measuring system of distributed fibers.
