Abstract: In order to improve the level of environmental protection, reduce energy consumption and save costs, an enterprise applied AI atomization technology to carry out sludge treatment in coke tower for environmental protection transformation. After the transformation, in the large blowing process of coke tower, the steam consumption is greatly reduced from 7.79 t/h before the transformation to 4.93 t/h after the transformation, the purified water consumption is greatly reduced from 2.93 t/h to 0.90 t/h, and the treatment capacity of sludge is greatly increased from 0.70 t/h to 6.99 t/h, which has remarkable energy saving and environmental protection effects. AI atomization system automatically controls the sludge treatment capacity and steam consumption, adjusts the operating parameters of coke tower in real time, and realizes automatic adjustment of sludge treatment capacity and steam consumption to achieve the optimal ratio on the basis of ensuring the safety of production process and coke quality. More than 6 000 t of sludge were recycled throughout the year, realizing 100% recycling of scum and oil sludge in the sewage plant, and significantly improving the resource utilization level of sludge in the whole plant. After the transformation of AI control technology is adopted for coke tower in this plant, the internal closed recovery and treatment of sludge in the refinery is realized, which eliminates the risk of environmental pollution, significantly reduces energy consumption and increases economic benefits.
