NOVELTY - Wind power coal natural gas system comprises e.g. an electrolysis water subsystem and a coal natural gas subsystem, where the electrolysis water subsystem is composed of an electrolysis water tank, an oxygen storage pot and a hydrogen storage pot. An electrode of the electrolysis water tank is connected to a power output end of a wind generator, and input openings of the oxygen and the hydrogen storage pots are connected to oxygen and hydrogen collecting tubes respectively. The coal natural gas subsystem is composed of a gasification furnace, a heat exchanger and a desulfurization tower.    USE - The wind power coal natural gas system is useful for generating oxygen and hydrogen by using wind powered electrolysis water.    ADVANTAGE - The system: produces oxygen and hydrogen by using wind power electrolysis water to make enable carbon monoxide and carbon dioxide in mixture gas generated from traditional gasification furnace to react with hydrogen to generate natural gas; and reduces carbon dioxide exhaustion and enlarges the wind power usage range.    DETAILED DESCRIPTION - Wind power coal natural gas system comprises an electrolysis water subsystem and a coal natural gas subsystem, where the electrolysis water subsystem is composed of an electrolysis water tank, an oxygen storage pot and a hydrogen storage pot. An electrode of the electrolysis water tank is connected to a power output end of a wind generator, and input openings of the oxygen storage pot and the hydrogen storage pot are connected to an oxygen collecting tube and a hydrogen collecting tube for collecting oxygen and hydrogen generated by the electrolysis water tank respectively. The coal natural gas subsystem comprises a gasification furnace, a heat exchanger, a desulfurization tower and a composition tower connected from head to tail. An output opening of the oxygen storage pot is connected to an oxygen inlet of the gasification furnace via a first pipeline, and an output opening of the hydrogen storage pot is connected to a gas inlet of the composition tower via a second pipeline.
