The system includes an industrial phased array radar body, a radar electromagnetic shield and an interlock cloth control system; wherein the industrial phased array radar body is in charge of obtaining level information; the electromagnetic shield is in charge of protecting the industrial phased array radar body in a high-temperature and high-pressure dust atmosphere; and the interlock cloth control system is in charge of carrying out analysis and judgment and charging task according to the level height data transmitted by the interlock cloth control system to control the final level shape to be in a predetermined shape. The inventive system can be applied in severe atmosphere of darkness, high temperature and dustiness to precisely describe the height information of each solid level point and obtain the kind and time of charging at different moments by the interlock with PLC or DCS; so that the shapes of a plurality of level layers and 3D images of solid levels are obtained.
Description
Technical field:
Industrial phased array radar is used in the fields such as metallurgy, chemical industry and cement building material that the present invention relates to, and to solid level, particularly blast furnace charge level is measured and imaging, and is realized the occasion of the chain control of the optimum closed loop of charge level distribution shape.
Background technology:
The mensuration and the dissection of blast furnace studies show that, charge level distribution shape and blast-furnace smelting stroke have relation closely, reasonably cloth and charge level distribution shape distribute to effective control blast furnace gas, make that cupola well is active, smooth operation of furnace, reduction coke ratio, save energy, stablize high yield, reduce aspects such as furnace wall erosion and prolongation blast furnace campaign important effect is arranged.Therefore, blast furnace charge level distribution shape control is the important step of the blast furnace ironmaking production automation, obtains the blast furnace charge level shape information real-time and accurately and has important value for the raising of blast furnace ironmaking productivity effect.Obtaining the constantly shape of charge level of variation of high temperature, high pressure, totally enclosed high furnace interior in real time, exactly, and carry out the chain closed-loop control of cloth in real time according to default shape of charge level, is a global technical barrier in metallurgy industry.
The charge level detection means of the most generally using mainly contains four kinds at present.
(1) mechanical stock rod method of masurement.Directly controlling level is carried out contact by machinery material chi at different positions and measure, adopt three material chis to realize that the controlling level of three different positionss detects usually, but can not reflect the shape of charge level, required Measuring Time is longer.
(2) measure the charge level method indirectly.Distribute by thermometric cross bar monitoring coal gas, infer indirectly shape of charge level.This method precision is low, and time of lag is long.
(3) infrared thermal imaging is measured the charge level method.It can obtain the heat distribution of charge level, but can not obtain shape of charge level.Because dust is serious to the influence of infrared medium window in the blast furnace, infrared thermoviewer is difficult to work on blast furnace.
(4) radar material surface measurement method.Promptly adopt the principle of microwave that shape of charge level in the State of Blast Furnace is carried out non-contact measurement.Mainly contain a radar single-shot list folding and unfolding mode at present, perhaps one one receipts formula of two radars for the method for radar imagery, generally adopts the mechanical type portable antenna to carry out the charge level imaging.
