ActiveCN104895675AEfficient use ofContinuous operation throughout the daySolar heating energySolar heat devicesCombustion chamberLiquid fuel
The invention discloses a solar energy and biomass complementary combined cycle power generating system capable of continuously running all day. Under the adequate light condition, the system directly utilizes high-temperature concentrating solar energy for completing the gasification reaction of solid hydrocarbon fuel by means of a high-temperature rotating type solar energy gasification reactor, and generated synthesis gas is purified and then is conveyed to a combustion chamber of the gas-steam combined cycle power generating system to generate powder; when the light condition is inadequate, the system utilizes a pyrolysis reactor and utilizes high-temperature molten salt storage solar energy for driving the solid hydrocarbon fuel for the pyrolytic reaction, and an atomizer is utilized for atomizing liquid fuel; and the atomized liquid fuel is conveyed to the combustion chamber of the gas-steam combined cycle system for power generation. The requirement that the solar energy is utilized for continuously converting the solid hydrocarbon fuel into the excellent fuel capable of being used by the gas-steam combined cycle system all day, and meanwhile, the system also can be suitable for other kinds of hydrocarbon solid hydrocarbon fuel like coal.

Process for producing polyphenyl thioether
The invention relates to a process for producing polyphenyl thioether, comprising the following steps of:, mixing hydrogenous sodium sulfide, lithium chloride and N-methyl pyrrolidone in the weight ratio of (20-25): (2-6): (70-80), co-boiling the mixture and inert gases at 150-210 DEG C for distilling and dehydrating; separating solvent by refining; respectively adding santochlor, solvent and lithium chloride in anhydrous sodium sulfide, separating after complete reaction to obtain polyphenylene sulfide; compositely washing the polyphenylene sulfide to obtain pure polyphenylene sulfide; and reclaiming the lithium chloride by filtering, reclaiming the solvent and flashly evaporating dimethylbenzene solution in a two-period mode and cooling and crystallizing. The invention has the advantages of low cost, simple process, excellent performance of synthetic resin and high solvent recovering rate.
