Abstract

The invention discloses a method and a device for three-stage separating biomass gasification. The device mainly comprises a reacting furnace, a pyrolysis chamber which is a biomass pyrolytic reaction chamber is arranged on the upper portion of the reacting furnace, a gasification chamber and a combustion chamber are positioned in the reacting furnace, the gasification chamber is positioned inside the combustion chamber, the pyrolysis chamber and the gasification chamber are connected with a feeding pipe, a flue gas channel is arranged outside the pyrolysis chamber and the feeding pipe, a feeding device is arranged on the upper pyrolysis chamber, the lower gasification chamber is communicated with the combustion chamber, a high-temperature gas extraction outlet is arranged in the middle of the gasification chamber, flue gas rises up along the flue gas channel from the combustion chamber to the periphery of the pyrolysis chamber and then is exhausted via a flue gas outlet, and the exhausted high-temperature gas is separated and purified by a separator prior to entering an air pre-heater. Three processes of a biomass gasification generating system are completely separated, the length of a reduction area is increased, and time and temperature required by tar pyrolysis are guaranteed, so that content of tar in the gas is reduced, gas generation rate of the gasification furnace is increased, and quality of the biomass gas is improved. The device has the advantages of convenience for temperature control, energy saving, environmental protection, operating continuity and the like.

Description

technical field [0001] The invention relates to biomass gasification technology, in particular to a three-stage separation type biomass gasification method and device. Background technique [0002] Biomass is a variety of organic matter formed through photosynthesis. It is directly or indirectly derived from the photosynthesis of green plants and can be converted into conventional solid, liquid and gaseous fuels. It is widely distributed and available in large quantities. It is a kind of Renewable energy, and also the only renewable natural raw material that contains hydrocarbon components and thermal energy, can be stored, uses biomass for energy utilization and chemical production, has CO 2 Characterized by zero emissions. With the decrease of traditional fossil energy reserves and the environmental pollution caused by the use of fossil energy, it has become the consensus of governments to attach importance to and develop renewable and environmentally friendly energy. ...
