This invention provides a method for preparing hydrogen and sulfur from solid waste gypsum through reduction and acidification in a cement kiln, relating to the field of solid waste disposal technology. The method involves targeted local modifications to a novel dry-process cement clinker rotary kiln production system. Using desulfurized gypsum, phosphogypsum, and other solid waste gypsum as raw materials, the gypsum is crushed, ground, preheated, and dehydrated. Then, it is calcined in a modified three-lobe gravity semi-suspended rotary kiln at 800–1100℃ in a reducing atmosphere to generate high-purity calcium sulfide. After sealed cooling, the calcium sulfide reacts with byproduct hydrochloric acid to produce high-purity hydrogen sulfide. The hydrogen sulfide is then used to co-produce hydrogen and sulfur via a medium-assisted electrochemical decomposition method, or high-purity sulfur can be directly prepared using the Claus process. This invention achieves full resource utilization of solid waste gypsum using existing cement kiln equipment, requires minimal modification, has low investment costs, and enables the cascade utilization of CO waste gas and kiln waste heat, reducing overall energy consumption by more than 30% compared to traditional processes.

This invention belongs to the field of high-performance parallel computing, specifically relating to a method for implementing SpMV based on an adaptive strategy on a CPU-DCU heterogeneous platform, aiming to improve the efficiency of SpMV computation. The method includes acquiring sparse matrix data at the CPU, converting the sparse matrix data into CSR format to obtain a CSR format array. Based on the CSR format array, adaptive decomposition is performed on the sparse matrix represented by it to obtain dense blocks and sparse blocks. An RDCSR format array is constructed based on the CSR format array; the RDCSR format array contains the CSR format array, an array recording the row indices of the dense blocks, and an array recording the row indices of the sparse blocks. The RDCSR format array is transmitted to the DCU, where, after adaptive thread allocation for the dense and sparse blocks at the DCU, SpMV computation is performed in parallel to obtain a merged computation result. The merged computation result is transmitted from the DCU to the CPU, and the computational performance of SpMV is evaluated.

It includes constructing a flexible DC interconnection model and establishing the capacity of the flexible DC converter station. P - Q The coupling characteristic curve is calculated. Based on the real-time reactive power demand of the system and the dynamic response weight of the flexible DC-DC converter station, the equivalent substitution coefficient of the flexible DC-DC interconnection for the traditional reactive power compensation device is calculated. Using the marginal cost analysis method, the marginal impact index of active and reactive power regulation demand on the overall net benefit of the system is calculated, and it is determined whether the flexible DC-DC interconnection device alone can meet the system's reactive power demand. If not, the reactive power gap is calculated and the traditional reactive power compensation device is configured. If it meets the demand, the optimal capacity configuration result of the flexible DC-DC converter station and the reactive power compensation device is obtained by maximizing the overall net benefit function of the system. This invention significantly improves the utilization rate of power electronic assets and the economy of power grid construction while ensuring the transient security support of the power grid.
