Description of the invention: [Technical field to which the invention pertains] The present invention relates to a blast furnace blasting wind grip device, and more particularly to a method and method for punctuality and its equipment. The kind of sufficiency of the two south of the drum blasts the wind "monitoring [previous technology] A blast furnace nozzle set 1 for the blast furnace is included - the front end has a mouth of the mi, - connected to the blast tube u is supplied to the mouth of the tympanic tube U at the front end of the ventilator U, and a regulating hole 13 disposed at the end of the vernier 11 and having a diameter of about 丨2. The side of the blasting windshield is provided with a side pipe 14' for a hot air from the side pipe 14 of the mountain management officer, and the pulverized coal discharged from the coal injection 12 is blown 3 The rigid end of y is opened and transported to a blast furnace, wherein the hot air is automatically blown out by the two-pressure air. Outside the front end opening of the blaster member group 1, a wind path region 15 is formed, and when the pulverized coal is blown out from the nozzle by the coal injection gun 12, it is blown to the wind along with the hot air transmitted by the side tube 14. When the run area 15 is for combustion, an operator can monitor the blowing condition of the pulverized coal and the combustion condition at the wind path area 15 from the peephole U. It is known to improve coal injection to save fuel costs. Therefore, in recent years, people from all over the world are more committed to how to improve the coal injection rate. As of the end of the year, the monthly average maximum coal injection rate can be as high as 266 kg/thm. Than (five) · ton hot metal (ton hot metal). However, the high coal injection rate causes the accumulation of unburned coal in the lower part of the blast furnace, resulting in a gradual decrease in gas permeability, which increases the resistance in the furnace, so that the pulverized coal cannot be smoothly transported; even, when the situation worsens, 1246537 It is more likely that the opening of the plugging end will be destroyed by the uncontained pulverized coal. The coal gun 12 and the blasting fu are burned due to the pulverized coal burning. + = The furnace has to be shut down for maintenance, which affects normal production and reduces The extra cost of the project has increased the cost of maintenance, manpower, and materials. In order to avoid the increase of the coal injection rate >%% 7 after the abundance of the equipment caused by the damage, the open business is usually a tribute to the patrol patrol, and the self-service hole 13 to monitor the pulverized coal injection situation and The combustion in the wind tunnel area (4) is generally = the mother's eight-hour patrol inspection _ times, but it is still insufficient. If the increase of the patrol video will increase the personnel cost, it will also predict or prevent the emergency situation. Extremely limited. It is a development system that monitors the dam tube π tube π or the wind tunnel area 15 by a number of types, for example, the blocker (four) developed by (7), which is installed in each- On the blasting nozzle group 1 for continuous detection on the line, once the large block of material is blocked at the nozzle of the blast tube u, the coal injection gun 12 is stopped from blowing (four) until the operator It is confirmed that the tube σ of the blast tube U has returned to a normal state, and the normal blowing of the pulverized coal can be resumed. However, the clogging detector can only measure the blockage of the bulk material, but it does not necessarily predict that the squirting of the coal injection 12 is unsatisfactory; in addition, the clogging detector is very expensive, and Since each blaster must be set up, it will greatly increase the burden on the equipment cost. In each blasting nozzle group 1 'to monitor the pulverized coal in the blast furnace, the blast furnace of the Bethlehem Steel Plant in the United States, the peephole 13 is provided with a movable fiber ferrule 1246537 = group 1 front end (four) burning condition, and Light_transfers the second degree of the difficult area at 15 degrees to enter (4) and 'sets the average brightness m as the control value. If the material brightness value is lower than the control value, it means that the coal injection is 12; the blowing is not smooth, even φ Tear the master of the ^ ^ % or even the order of the temple, the operator can immediately clean up the "coal gun 12. However, its (four) value is solid ^ = (10) "the brightness value produced may be Due to its various factors such as the quality of pulverized coal, its normal brightness value is lower, even lower than its so-called regulatory value, and it may cause misjudgment. - Even low, so that various emergencies can be discovered in time. , immediately deal with, the second will: the loss to the lowest, how to set up a low cost and high accuracy: the monitoring method or monitoring equipment 'to allow the operator to: when the pulverized coal in the wind tunnel area is blocked or excessively burnt Can immediately infer the current =: Condition: and in the first time Hand handling, to avoid greater damage, Bay! <4 is not important, but also become a relevant improvement of the relevant industry. [Inventive content] Therefore, the object of the present invention is to provide a low cost and accurate The blast furnace blaster wind-path area monitoring method and equipment for monitoring the pulverized coal combustion condition in the blast furnace blaster wind-path area, and the blasting nozzle group is installed in a blast furnace. Included is a front: open, with In and at the end is provided with a peephole and can be blasted into the wind two, and a blast tube can be sprayed to the front of the blaster a coal injection gun at the opening π, the air flow conveying the pulverized coal to the opening of the blast tube and the blast furnace jointly defining a blast furnace blast nozzle wind path region, the blast furnace blast nozzle wind diameter region The monitoring method includes: 1246537 JA) by means of the light debt measuring device, through the peephole, the line continuity value and the redundancy degree are sub-intensified, and the corresponding bright is obtained, and the straw field is connected to the The light ray "nose treatment device is based on the brightness values measured by the step (4) And for each: the establishment of the production value - the corresponding reference range, the way of establishing each reference range = the measurement time point corresponding to the brightness value, the calculation of the "unit period" and the gain of the unit period The values of all the luminance values are defined by the upper limit value and the lower limit value obtained by the operation of the arithmetic processing device, and (c) the brightness values obtained per time are compared with the corresponding reference ranges respectively. When the brightness value falls outside the reference range, a warning message is issued. The device for monitoring the wind tunnel area of the blast furnace blaster includes, by means of the peephole, continuously detecting the brightness of the blast furnace blaster wind path region on the line and quantifying to obtain a plurality of sequentially a light detecting device for brightness value, an arithmetic processing device for continuously processing a plurality of reference ranges of respective exclusive brightness values based on respective brightness values measured by the light detecting device, and an electrical connection The alarm processing device is configured to issue a warning message when a brightness value exceeds its exclusive reference range. [Embodiment] The foregoing and other technical contents, features and effects of the present invention will be apparent from the following detailed description of a preferred embodiment of the accompanying drawings. Referring to Fig. 2, the blaster member set 1 is mounted in a blast furnace (not shown) and the preferred embodiment of the apparatus 2 for monitoring the blast furnace blaster wind path region of the present invention is connected. The ventilating nozzle member set 1 is as shown in FIG. 1, and the device 2 includes a photometer 3, a signal converter 4, and a computer 5 including an arithmetic processing device 51 and a warning device 52. Referring to FIG. 3, the photometer 3 includes an L-shaped hollow tube 33 having a first tube portion 31 and a first tube portion 32 interposed therebetween and substantially perpendicularly connected to the first tube portion 32. The first and second tube portions 31, 32 in the hollow tube 33 have a reflective surface 341 for reflecting light and a glass 34 for transmitting the light transmitting surface 342, and a second glass is disposed at the second surface. A light sensor 36 including a photo-electric body 35 is disposed in the tube portion, and a terminal 37 connected to the light sensor 36 and disposed on the port 321 of the second tube portion. The signal converter 4 is a light sensor 36 electrically connected to the photometer 3. The arithmetic processing device 51 of the computer 5 is electrically connected to the signal and converted to 4' and the arithmetic processing device 51 and the warning device 52. The first tube portion 31 of the photometer 3 is detachably mounted on the peephole hole 13 of the blasting nozzle assembly 1, and the L-shaped hollow tube 33 is opened with a The viewing aperture 13 is located in the visual aperture 3 i} of the same horizontal plane. The glass is again placed at an angle of 45 degrees, and its reflecting surface 341 faces the peephole U, and its transmitting surface 342 faces the viewing hole 311. See also Figure 3. By connecting the first tube portion 31 to the 1246537 of the peephole hole 13, the light at each moment of the air volume region 6 in FIG. 2 can be successively entered into the first tube portion 3 1, when arriving at the In the case of the glass 34, a portion of the light is reflected by the reflecting surface 341 into the second tube portion 32, and is transmitted to the pupil light to be 3 6 to measure the brightness at each moment and quantize it. Each becomes a corresponding brightness value. The light of the other portion is refracted and exits the transmissive surface 342 and passes through the visual hole 311. Therefore, a patrolman can observe the pulverized coal combustion of the air volume region 6 through the glass 34 from the visual hole 311. Happening. The brightness value measured by the light sensor 36 at each moment is converted into a digital signal of the phase and is sent by the terminal + 37 and transmitted to the signal converter 4 to Each of the digital signals is converted into a corresponding current signal that can be received by the arithmetic processing unit 51 of the computer 5, and then the current signals are sequentially transmitted to the arithmetic processing unit 5 i. The X operation processing means 51 is for further synthesizing the received current signals ' of the respective luminance values into a reference range for comparison with the respective luminance values. Each reference range is measured by the brightness value of the dragon: point, forward calculation - unit period, for example, 60 minutes, and based on all the brightness values measured within the 6 minutes, through the operation processing The device performs arithmetic processing on all luminance values to form a reference range. The benchmark range is established by first calculating the total party value measured in 6G minutes and __average, and then multiplying the average by 1.37 and 〇7 times respectively. The upper limit value and the lower limit value are obtained. When the brightness value of the time exceeds the corresponding reference range, for example, above the upper limit value or below the lower limit value, the warning device 52 issues a warning message. It can be a sound of 10 1246537, or a warning screen, so that the operator knows that the brightness value of the time exceeds the reference range, and determines whether the combustion condition of the air volume area 6 is abnormal in the first time. And on-site investigation for immediate processing. Therefore, the brightness of the wind tunnel area of the oven blower is subjected to dynamic ground detection, and each brightness value can also be converted into a waveform diagram of time as shown in FIG. 4 with respect to the photometer signal. The operator interprets and reaches the operator to monitor whether the pulverized coal in the wind tunnel area of the blast furnace has normal combustion. It can be seen from the above configuration that the method for monitoring the wind tunnel area of the blast furnace blast furnace of the present invention and its δ have the following advantages: (1) High reliability of detection: 0々八心々一赞刊The operator who is inspecting the blast furnace blaster wind tunnel in the high temperature of the blast furnace is intended to pass through the visual hole 311 of the photometer 3 toward the height.
