Abstract
The utility model provides a on-line monitoring device for blast-furnace tuyere operating condition, which comprises a monitoring and controlling system, wherein the monitoring and controlling system is connected with the end of an eye hole of the blast-furnace tuyere via a detector; the detector is connected with a fixing ring of the eye hole of the blast-furnace tuyere via a connecting bracket; the detector comprises a neutral filter, a pick-up lens and a camera, and disposed in a hollow protection box; a cooling fan is disposed at the front end of the bottom of the protection box; and the monitoring and controlling system comprises a digital image collection/compression card, a data collection/conversion card, an industrial control main machine, monitor and accessory equipment. The coal powder blowing state before the blast-furnace tuyere, the coal powder combustion state in convolution zone, and the radiation temperature image of burning can be detected via the eye hole; the digital signal taken by the camera can be transmitted to the industrial control main machine in the blast furnace central control room via video transmission cable, processed by the monitoring and controlling software, and displayed on the monitor to timely on-line monitoring the operating condition at blast-furnace tuyere.
Description
Technical field
The utility model relates to the blast-furnace tuyere monitoring of working condition device of the usefulness of metallurgical industry, is used for timely monitor blast-furnace tuyere working condition.
Background technology
Blast-furnace tuyere is the unique position that can spy on high furnace interior, and the district of circling round, air port is the source region of blast furnace heat and coal gas, and it is significant to guaranteeing smooth operation of furnace in time to monitor the circle round combustion position, temperature distribution in district of blast-furnace tuyere.
At present, some smelters such as external Holland, Japan, and units such as domestic Iron and Steel Research Geueral Inst, Wuhan Iron and Steel Company successively are provided with detector at blast-furnace tuyere, the combustion position of monitoring blast-furnace tuyere and flame temperature etc.But existing blast-furnace tuyere monitoring device is equipped with complicated, is not easy to loading and unloading, and the air port is difficult in maintenance, is unsuitable for the blast furnace practical application.Therefore, apply slowly.
Chinese patent CN02290356.9 " blast-furnace tuyere state of combustion monitoring device " is to be connected water cooler of parts such as having optical filtering, object lens etc. successively between air port vision slit and pick up camera, has many, the baroque defectives of parts.
Technology contents
At the prior art above shortcomings, the purpose of this utility model provides a kind of blast-furnace tuyere operating mode on-Line Monitor Device simple in structure, easy to use.
The technical solution of the utility model is: blast-furnace tuyere operating mode on-Line Monitor Device, comprise monitoring meter control system, and it is characterized in that monitoring meter control system is connected with blast-furnace tuyere peep hole end by detector; Detector is connected by attachment bracket with the set collar of blast-furnace tuyere peep hole; Detector is considered mating plate, pick-up lens and pick up camera by neutrality and is formed, and is located among the protection box of hollow; Protection box bottom front is furnished with a cooling fan; Monitoring meter control system is made up of numerical imaging collection/compressing card, data gathering/transition card, industrial control host, watch-dog and auxiliary facility.Combustion case by breeze blowing situation before the detectable blast-furnace tuyere of peep hole, the district's coal dust that circles round and incendiary radiation temperature image etc., the data image signal of pick up camera picked-up is sent to the industrial control host of blast furnace Central Control Room by video transmission cable, after the processing of monitoring meter control system software, can carry out in good time on-line monitoring to the blast-furnace tuyere operating mode by watch-dog.
Further improve and be to adopt the attachment bracket that flexibly connects to be connected between described set collar and the detector.Can blast-furnace tuyere be the center left rotation and right rotation like this, be convenient to loading and unloading and maintenance that end is spied in the air port.
By monitoring device described in the utility model, except that can the described pulverized coal injection in blast furnace of qualitative analysis patent CN9624453.3, the situation such as burning, can also in good time collection circle round district's combustion flame radiation image, the quantitative district's temperature of circling round that analyzes digital radiation image correspondence, and can carry out the inquiry of graphic information and temperature data and playback etc. according to the time to history image.Neither influence the conventional maintenance in air port, again can be in good time with the pulverized coal injection in blast furnace situation, the district's combustion position that circles round is sent to the blast furnace watch-keeping cubicle, shows, writes down the combustion flame radiation image automatically and the district's temperature distribution of circling round.
Description of drawings
Fig. 1 is a blast-furnace tuyere monitoring of working condition apparatus structure synoptic diagram;
Fig. 2 is the A-A sectional view of the utility model set collar.
Specific embodiments
As shown in Figure 1, the utility model blast-furnace tuyere operating mode on-Line Monitor Device comprises set collar 2, attachment bracket 3, detector and monitoring meter control system.Detector is considered mating plate 6, pick-up lens 7 and pick up camera 11 by neutrality and is formed; Monitoring meter control system is made up of machine 14, watch-dog 15 and auxiliary facility in numerical imaging collection/compressing card 13, data gathering/transition card, the industry control, adopts existing mature technology to get final product.
Set collar 2 is made of two semicircular ring, is fixed on outside blast-furnace tuyere peep hole 4 main shafts; Peep hole 4 ends in air port also are provided with band thermal baffle and silica glass 9 and spy on port lid 5; Protection box 8 is hollow housings, and the housing bottom front end is furnished with a cooling fan 10; Set collar 2 is connected by attachment bracket 3 between the box 8 with protection, adopts flexible connection, can blast-furnace tuyere be the center left rotation and right rotation, is convenient to loading and unloading and maintenance that end is spied in the air port.Detector places in the protection box 8; combustion case by breeze blowing situation before the peep hole 4 detectable blast-furnace tuyeres, the district's coal dust that circles round and incendiary radiation temperature image etc.; the data image signal of pick up camera 11 picked-ups is sent to the industrial control host 14 of blast furnace Central Control Room by video transmission cable; after the processing of monitoring meter control system software, can carry out in good time on-line monitoring to the blast-furnace tuyere operating mode by watch-dog 15.
Among the figure, 1-plug core, 12-tie cable plug.
Its principle of work: the air port circle round district's internal combustion the high temperature high light by air port peep hole 4, thermal baffle and silica glass 9, neutral consider mating plate 6 after, import pick-up lens 7 into, pick up camera 11.The digital picture of pick up camera 11 picked-ups is transferred to compression of images/capture card 13 through video coaxial cable, and through after the monitoring meter control system software processing that prestores in the industrial control host 14, on Central Control Room watch-dog 13, show circle round the burning radiation image in district, the temperature and the distribution situation of each point in good time, and can carry out the inquiry of graphic information and temperature data and playback etc. to history image according to the time by process software.The cooling of dispelling the heat of 10 pairs of optical filterings 6 of cooling fan, 11 3 opticses of pick-up lens 7 pick up cameras.
