Embodiment Construction
[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Before introducing the specific solutions of the present invention, the technical ideas are firstly explained.
[0029] According to engineering practice, we can know that a large amount of combustible gases, such as hydrogen, carbon monoxide, and methane, will be produced during the pyrolysis process of organic solid waste. Therefore, if the hydrogen in the pyrolysis gas can be extracted and utilized as a resource, good economic and environmental benefits can be produced without wasting resources.
[0030] According to research, with the increase of pyrolysis temperature, the content of hydrogen in pyrolysis gas will gradually increase. "Industrial Solid Waste Treatment Technology" published by Sinopec Press gives...
