Abstract

The invention relates to a system for producing a clean energy. The system comprises a gasification device, a coking device, a shift reaction and hydrogen purification device, a gas purification device, hydrogen transporting equipment, a carbon dioxide storage device, an oxynitride treatment and water vapour recycling device, oxygen and oxygen-enriched air supplying equipment, heavy metal treatment equipment, slag separation equipment, a cement plant, a coal material plant and a water vapor storage tank. Due to the arrangement of the gas purification device, the shift reaction and hydrogen purification device, a coal tar separation device, a cracking device and a coal gas purification device, the coal gas generated by coal gasification and coking is purified and converted into the hydrogen, thereby providing the valuable clean energy. The hydrogen serves as a heating fuel for the whole system, so that the carbon dioxide is not generated during the combustion process in the heating manner; and the fuel gas generated by the combustion is discharged after oxynitrides in the fuel gas are removed. Therefore, pollutants are reduced and avoided being generated and diffused. By utilizing a wall-dividing-type rotary kiln, the fuel gas generated by the combustion is prevented from polluting, coking and gasifying products.

Description

technical field [0001] The invention belongs to the technical field of clean energy production and environmental protection, and relates to a clean energy production system. Background technique [0002] Environmental pollution will not only cause direct damage and impact to the ecosystem, but also cause great harm to the ecosystem and people's lives. The most direct and easily felt consequence of environmental pollution is to reduce the quality of the human environment and affect the quality of life, health and production activities of human beings. For example, urban air pollution causes air pollution, and people's morbidity rate increases; water pollution deteriorates the quality of water environment, and the quality of drinking water sources generally declines, threatening people's health, causing premature birth or deformity of fetuses, etc. Serious pollution incidents not only bring health problems, but also social problems. With the intensification of pollution and ...
