Embodiment

[0040] Embodiment: Using wood chips to produce biomass gas and carbon adsorption materials

[0041] The biomass rotary pyrolysis and gasification equipment with internal and external heat integration of the present invention is adopted, the raw material is wood chips, the length is about 20-40mm, and the moisture content is 15-20%. First turn on the pellet burner, raise the temperature of the externally heated rotary furnace to 500-700°C, put the wood chips into the feed bin, the wood chips complete the pyrolysis reaction in the externally heated rotary furnace and enter the internally heated gasification device, and send them into the water The mixture of steam and air, the ratio of water vapor to air is 2:1, and the charcoal gasification and activation reaction occurs in the internal heating gasification device. The reaction temperature is 1100-1200 ℃ to generate gas and activated carbon, and part of the generated gas is sent to the external heat The combustion chamber of th...

Abstract

The invention discloses an internal and external integrated biomass rotation pyrolysis gasification device and application. The device is mainly composed of a feeding device, an external heating type pyrolysis device, an internal heating type gasification device, a sealing device, a discharging device and a burner and the like. The feeding device, the discharging device and the sealing device ensure sealing performance of the pyrolysis gasification device and continuous operation of pyrolysis gasification reaction. High-temperature gas is reused to provide heat for external heating pyrolysis, and energy consumption is reduced. Mixed gas of steam and air serves as a gasifying medium to undergo gas activation reaction together with materials in an internal heating type converter, and gas and activated carbon are generated.

Description

technical field [0001] The invention relates to a rotary pyrolysis gasification device and method, in particular to a biomass rotary pyrolysis gasification device with integrated internal and external heat and its application. Background technique [0002] Biomass is a clean and renewable energy source. Biomass pyrolysis gasification is an important way of biomass utilization. Biomass pyrolysis refers to the thermal decomposition of biomass raw materials under the condition of isolation of air or adding a small amount of air to produce condensable and non-condensable gases and solid carbon and other substances in different forms. The calorific value of the gas obtained by pyrolysis is generally 12000kJ / Nm 3 The above; Biomass gasification refers to the process of gas-solid reaction between biomass raw materials and gasification agents, such as water vapor, oxygen or air, under certain temperature conditions. [0003] In the domestic industrial application of biomass pyroly...
