NOVELTY - Directly applying large-scale non-grid-connected wind power in the production of liquefaction coal oil comprises: (a) using large-scale non-grid-connected wind power as a working power supply of electrolytic bath; and (b) entering carbon flow and water flow obtained by a routine method into a coal gasifier.    USE - The method is useful for directly applying large-scale non-grid-connected wind power in the production of liquefaction coal oil (claimed).    ADVANTAGE - The method improves the productivity of coal oil and doubling the output; lowers the investment cost and operation cost spent on producing coal oil dramatically; and decreases the discharge of greenhouse gas carbon dioxide below 10 percent of traditional production discharge; in the technology, the wind energy is effectively used; it is broken through that the routine large-scale wind power must be connected, as a result, a cosmopolitan difficulty problem that the connection contribution rate is only 10 percent is solved; moreover, it is achieved that the large-scale wind power can be made full of use in the technology for producing liquefaction coal oil, so the green coal chemical engineering is possible.    DETAILED DESCRIPTION - Directly applying large-scale non-grid-connected wind power in the production of liquefaction coal oil comprises: (a) using large-scale non-grid-connected wind power as a working power supply of electrolytic bath; the oxygen and hydrogen obtained by electrolyzing water are separately entered into an oxygen storage pot and a hydrogen storage pot via the electrolytic bath; moreover, an oxygen compressor is connected with an outlet of oxygen storage pot; according to production need, the pressure at the oxygen outlet is adjusted; a hydrogen compressor, a heat exchanger and a flow regulating valve are connected with outlet of hydrogen storage pot; according to production need, the temperature, pressure and flow at the hydrogen outlet are regulated; and (b) entering carbon flow and water flow obtained by a routine method into a coal gasifier; the oxygen in the oxygen storage pot of (a) is used as gasifying agent; a proper amount of regulated oxygen flow is entered into the coal gasifier, and then connected with carbon-water mixture flow to generate a water gas flow rich in carbon monoxide (CO), carbon dioxide (CO2) and hydrogen gas (H2); after being compressed by the compressor, exchanged with heat via the heat exchanger and rectified by a rectifying device, the water gas flow is entered into a slurrying bed reactor together with hydrogen output by the flow regulating valve; after the step of reacting, a coarse product gas flow rich in alkane, CO, CO2 and H2 is obtained; after the coarse product gas flow undergoes some technological treatments such as fractional distillation and separation by a distilling/separating device, naphtha isomerization, deparaffinating and so on, the gasoline, diesel oil and liquefied petroleum gas are obtained; the un-distilled and un-separated water gas flow rich in CO, CO2 and H2 can be returned to the slurrying bed reactor via a return pipe for continuous circular reaction. INDEPENDENT CLAIMS are:    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the process for directly applying large-scale non-grid-connected wind power in the production of liquefaction coal oil.
