Research on Low-Carbon Operation Mechanism and Environmental Value Transformation of Waste Feed Resource Utilization Equipment under a Dual-Carbon Background
Main Article Content
Abstract
Under the dual-carbon situation, the carbon emission intensity of the equipment for recovering resources from waste feed is high and it is difficult to obtain environmental value. Firstly, an equipment-level carbon flow traceability model is established to find the carbon hotspots; then, a time-varying load-following control method based on moisture content is proposed to realize the on-demand heating; secondly, a multi-machine energy efficiency redistribution strategy under time-of-use electricity pricing and carbon factor constraint is established; finally, a life-cycle value conversion path is constructed to convert the carbon reduction contribution into carbon asset. The experimental results show that the power consumption per ton under follow-up control is reduced from 42.4 kW·h·t-1 to 33.9 kW·h·t-1, representing a 20.0% energy reduction, while the integrated operational carbon intensity (including heat and power) is reduced by 19. 4%; the peak power and daily cost are reduced by 81.0% and 31.0% respectively after the implementation of energy efficiency redistribution strategy; the present value of implied environmental value is 12,800 yuan, which accounts for 6.5% of the investment. The conclusion shows that carbon reduction can be accumulated into carbon asset by opening up the conversion path; and dual-carbon synergy of equipment is improved. The near-infrared moisture measurement and load-following control provide an optical sensing basis for low-carbon equipment operation.
