A cooling system and intelligent control method for high heat load zone of blast furnace

This invention relates to the field of blast furnace cooling systems, specifically to a cooling system and intelligent control method for high heat load zones in blast furnaces. The system includes: cooling walls, refractory bricks, copper cooling elements, a composite packing layer, and an intelligent control unit. Copper cooling elements are spaced apart in the gaps between adjacent cooling wall sections, with the hot surfaces of the copper cooling elements receding inwards relative to the hot surfaces of the cooling walls. The composite packing layer fills the gaps between the copper cooling elements and the cooling walls, comprising a high thermal conductivity packing area and a low thermal conductivity packing area. The high thermal conductivity packing area is located at the mating gap between the copper cooling elements and the cooling walls, while the low thermal conductivity packing area is located on the hot surface side of the copper cooling elements. The intelligent control unit acquires slag skin condition information from the slag skin adhesion zone and dynamically adjusts the cooling parameters flowing through the copper cooling elements based on this information. This invention can improve system heat transfer efficiency and achieve proactive and precise control of slag skin thickness and long-term stability of the blast furnace internal structure.

This application belongs to the interdisciplinary field of computer vision and smart agriculture, and discloses a method, device, and medium for 3D reconstruction of seedlings based on active lighting and probabilistic occupancy. The method includes: acquiring image sequences under multi-angle active lighting using a single fixed camera and multiple calibrated light sources on a circular array; obtaining photometric properties unaffected by specular reflection through polarization component decoupling; constructing a probabilistic 3D voxel mesh; for each light source, locating surface points by constructing active lighting and shadow epipolar geometric constraints and calculating the geometric intersection of the line of sight and the light ray; introducing a dynamic confidence gate and a neighborhood game mechanism to construct a void topology protection strategy, updating the occupancy probability of voxels on the light path in an adaptive probabilistic manner; finally, correcting the probability field through multi-source shadow consistency verification, and generating the final 3D geometric model using a moving cube algorithm. This invention enables high-precision 3D reconstruction of seedlings under static occlusion without moving the camera or objects.
