AI Technical Summary
Large coal storage and distribution tanks are prone to material blockage during use, which is difficult to solve effectively with existing technology. This leads to discontinuous coal feeding and flow fluctuations, affecting the stability of coke oven production and coke quality, and may even cause shutdown accidents.
The gas-liquid-thermal-acoustic synergistic anti-blockage and unblocking method is adopted. By setting up multiple air cannons, sonic soot blowers, steam fumigation and water injection devices in the coal tank, combined with hierarchical linkage control logic, a three-dimensional anti-blockage and unblocking method is achieved in the whole area to ensure the stability of coal tank feeding.
It achieves stable coal feeding from the coal hopper, eliminates material shortages and flow fluctuations, ensures continuous and efficient operation of the coke oven, reduces equipment wear and maintenance costs, and improves the consistency of coke quality.
