Abstract
The utility model provides a blast furnace laser detecting instrument, which comprises a laser generating a laser light into the furnace ,and a video camera arranged on the furnace body, the video camera can be used to produce a furnace inner image by acquiring the laser light generated by the laser, the furnace inner image comprises a laser image formed from the fact that the laser light is across the powder dust and/or the fume inside the furnace; the utility model can detect an on-line inner data of a blast furnace in real time such as equipment operation state, charging process and material surface state and so forth by laser and image shooting methods according to the principle that a laser can be across through the powder dust or the fume inside a furnace to form a laser trace (laser image).
Description
Technical field
The utility model relates to a kind of blast furnace laser detector, more particularly, relates to the laser detector of equipment running condition, charging process and charge level situation in the stove of surveying blast furnace.
Background technology
Usually and since the hermetic type Industrial Stoves for example blast furnace have furnace inner environments such as high temperature, high pressure, high dust, high humidity, operator can only go to infer in the stove by the numerical value of conventional sense instrument such as temperature, pressure, flow and to produce and equipment operation condition.In order to obtain required in-furnace information, people have developed for example means of detection such as infrared scan, microwave scanning of scan type, but the means of detection of this scan type needs the corresponding instrument that receives to handle the scan-data that obtains with complicated computing system.
In addition, people have also developed infrared photography type for example the applicant's patent of invention ZL 02 121548.0 and ZL 2,003 1 0122476.4 and the disclosed means of detection of International Patent Application WO 04/002136A1.But, because such means of detection is that the infrared light that utilizes furnace charge to send comes pickup image, under the lower state of charging process and charge-temperature, because infrared light weak strength, just can't obtain infrared image clearly, thus the situation of equipment operation, charging process and charge level in can not the real-time detection stove.In fact, the means of detection of the above-mentioned type can only be in the of short duration time or is obtained in-furnace information under given conditions, also can't reach the purpose that real-time online is surveyed situation in the stove at present.
The utility model content
The purpose of this utility model provides a kind of blast furnace laser detector, and it can survey the in-furnace information for example interior equipment running condition of stove, charging process and charge level situation etc. by real-time online.
Blast furnace laser detector of the present utility model comprises: laser apparatus produces the laser that enters in the stove; And video camera, be arranged on the body of heater, can obtain and utilize the laser that described laser apparatus produces and image in the stove that forms, image comprises by described laser and passes dust and/or the formed laser pattern of smog in the stove in this stove.
The utility model passes in the stove dust according to laser or smog can form this principle of laser trace (laser pattern), by utilizing laser and shooting means, the internal information of can real-time online surveying blast furnace is equipment running condition, charging process and charge level situation etc. for example.
Description of drawings
Following with reference to accompanying drawing, by preferred embodiment the utility model is further described, wherein:
Fig. 1 is the structural representation of the utility model first embodiment;
Fig. 2 is the structural representation of the utility model second embodiment.
Embodiment
Referring to Fig. 1 and Fig. 2, blast furnace 1 is provided with laser inlet 2 and video camera 3 above benchmark charge level 4, laser inlet 2 and video camera 3 are arranged on the blast furnace 1 by rights, be under the normal circumstances, high furnace interior not can by laser enter the mouth 2 and video camera 3 be in communication with the outside, and video camera 3 can obtain image in the required stove that utilizes laser 5 and form.One or more laser inlet 2 and/or video camera 3 can be set as required.Should be noted that the laser apparatus (not shown) can be arranged on blast furnace 1 outside, but the portion that also can set within it.Because environment such as the high temperature of high furnace interior, high pressure, high dust, high humidity, common image capture method can't obtain in-furnace information at all.But, different working conditions according to blast furnace 1 inside, utilize laser 5 can be in stove to form the principle of laser trace (laser pattern) (if there is not the spike effect of dust and smog under high dust and/or the high smog environment, then obviously can not form this laser pattern), can be in the stove that blast furnace 1 inner formation can be obtained by video camera 3 image; In the charging process of blast furnace and shape of charge level and the stockline degree of depth not simultaneously, stove inner laser pattern can present difference or produce corresponding distortion.Utilize watch-dog to monitor in-furnace information,, can understand for example equipment running condition, charging process and charge level situation etc. according to obtain image in the stove that has laser pattern.
In addition, as required, can be with image input computer processing system (not shown) in the stove that has laser pattern that is obtained, for example according to the comparative result of predetermined stove inner laser pattern, quantitative Analysis is also exported in-furnace informations such as shape of charge level, the stockline degree of depth and equipment running condition.Therefore, by the variation and the corresponding calculated result of image in the stove, operator are the in-furnace informations such as running condition, charging process, shape of charge level and stockline decline process of the interior equipment of near real-time quantitative monitoring blast furnace directly.
It will be appreciated by those skilled in the art that above-mentioned embodiment only works the effect of the present utility model of explaining, and not should be understood to any restriction that it is made.For example, be appreciated that the utility model is not limited to only be applied to blast furnace, according to actual needs, can also be used to survey the Industrial Stoves under any similar Working environment or the internal information of container.
