Direct gasification method and apparatus for charcoal and carbon compound

Abstract

The invention relates to the technical field of gasification of charcoal and discloses a direct gasification method for charcoal and a carbon compound. According to the method, the charcoal and the carbon compound are placed in the front section of an enclosed cavity and mixed with water or hydrogen; then the obtained mixture is heated to more than 800 DEG C, and high temperature and high pressure are formed in the cavity; the charcoal and the carbon compound become a variety of elemental atoms or micro-molecules through pyrolysis, and the elemental atoms or micro-molecules recombine with hydrogen atoms and oxygen atoms produced after pyrolysis of water or hydrogen atoms produced after pyrolysis of hydrogen to form high-calorific-value gases (mainly including methane and carbon monoxide) which are mainly low molecules (also called as small molecules); and a recovery chamber is arranged at the rear section of the enclosed cavity for collecting the high-calorific-value gases and a plurality of solids. The whole gasification process is carried out in the enclosed cavity, and the high-calorific-value gases and a plurality of solids are eventually recovered by the recovery chamber communicated with the front section, which enables air pollution to be completely prevented. In the gasification process, energy release and absorption in the process of pyrolysis of the charcoal, the carbon compound and water or hydrogen into elemental atoms or micro-molecules and in the process of atom recombination are directly utilized, so minimum energy consumption is realized and good economic benefits are obtained; moreover, the method is simple and can realize streamline production in a completely enclosed production line in actual production.

Description

technical field [0001] The invention relates to the technical field of charcoal gasification, in particular to a direct gasification method and device for charcoal and carbon compounds. Background technique [0002] my country belongs to the energy pattern of rich coal, poor oil and little gas. Carbon and carbon compounds occupy a dominant position in energy supply in our life, industry and commerce, and the energy supply is mainly dominated by coal. [0003] In 2012, my country's coal accounted for about 66.5% of the total energy consumption. However, coal is a complex organic polymer compound dominated by carbon elements. When it is used for direct combustion, it will have incomplete combustion, smoke and dust. Phenomenon, and accompanied by coal-associated biosulfur, mainly sulfur dioxide, causing energy waste and environmental pollution and other problems. At present, one of the main causes of smog in China is this problem. In order to effectively solve the problems of w...
