High furnace burden face measurement and control system based on industrial phased array radar

Abstract

A system for measuring and controlling blast furnace level based on an industrial phased array radar relates to the industrial phased array radar used in the fields of metallurgy, chemical engineering, cement building materials. 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: [0001] The invention relates to the occasion where industrial phased array radar is used in the fields of metallurgy, chemical industry, cement building materials and the like to measure and image the solid material level, especially the blast furnace material level, and realize the optimal closed-loop chain control of the material level distribution shape. Background technique: [0002] The measurement and anatomical research of the blast furnace show that the distribution shape of the material surface is closely related to the smelting process of the blast furnace. Reasonable material distribution and distribution shape of the material surface can effectively control the gas distribution of the blast furnace, making the hearth active, the blast furnace moving forward, reducing the coke ratio, It plays an important role in saving energy, stabilizing high production, reducing furnace wall erosion and prolonging the life of blast furnace. Therefore, the distr...

Problems solved by technology

But the problem that exists in this invention is: what radar adopts is the low-frequency radar (VEGAPULS56K) of 6.3GHz, the launch angle of 20 ° of angles, horn mouth antenna, DN150, and the echo strength of this radar is under the situation of measuring solid material level, Especially in the state of high-temperature dust, because the frequency is lower than that of the 26GHz echo signal, the echo is weak, and it is easy to lose the wave

The system uses 26GHz radar wave, radar emission angle of 8°, and horn antenna DN100 to measure the incidence and reflection of solid materials with irregular rough surfaces, but the system has 3-10 radar measurement units, typically 6 radars, many auxiliary units installed, many holes are drilled on the top of the blast furnace, only 3-10 imaging points, and the imaging resolution is low
