Abstract

The invention provides a biomass combustible gas extraction method. The biomass combustible gas extraction method comprises the following steps: A1, biomass resources are placed into a combustion furnace to be combusted, the combustion temperature in the combustion furnace is 1000-1800 DEG C, the combustion time is 1-2 h, and the pressure in the furnace is 5-6 MPa; A2, gas obtained through combustion is guided out, cooled and adsorbed, in the cooling and adsorption processes, the temperature of the passing gas is decreased to be 100-200 DEG C, and the cooling time is 2-4 h; and A3, the obtained cooled gas is purified, and purification residues are collected. Firstly, full combustion is achieved during primary combustion, thus multiple impurities introduced by low-temperature combustion arereduced, subsequent multi-stage separation and purification treatment is facilitated, the utilization efficiency of the biomass resources can be significantly improved, and large-scale and standardized treatment of the biomass resources is facilitated; and when the gas generated through combustion is treated, reasonable graded treatment is adopted, thus all components contained in the generated gas can be efficiently and orderly separated, and the biomass resources are fully and comprehensively utilized.

Description

Technical field: [0001] The invention relates to the technical field of biomass resource utilization, in particular to a biomass combustible gas extraction method and extraction equipment. Background technique: [0002] With the continuous acceleration of the industrialization process and the continuous improvement of the people's production level, my country's dependence on non-renewable fossil energy, mainly coal and oil, has also been continuously strengthened. In order to prevent the excessive exploitation and utilization of non-renewable fossil energy , the adjustment of my country's energy use structure is imminent. At present, besides non-renewable fossil energy, the most abundant reserves on the earth are biomass resources, and the rational use of biomass resources can not only solve the problem of energy use structure adjustment, but also protect Environment, promote sustainable development, biomass resources are the fourth largest resource on the earth, its abundant ...
