Pyrolysis-gasification integrated conversion and utilization system and method for waste biomass resources

Abstract

The invention relates to a pyrolysis-gasification integrated conversion and utilization system for waste biomass resources and a method used by the same. The system comprises a pyrolysis device, a gas feeder, a multifunctional heat exchange device and a waste heat supply device, wherein a gas channel of the multifunctional heat exchange device is respectively connected with the pyrolysis device and the gas feeder, and a condensed water channel is connected with the waste heat supply device. The method comprises the following steps: delivering the raw material biomass waste into the pyrolysis device for high temperature pyrolysis to obtain mixed gas containing combustible gas, tar gas, acetic acid gas and water vapor; and introducing the mixed gas into the multifunctional heat exchange device for heat exchange and separating combustion gas from mixed liquor of tar and acetic acid after heat exchange, wherein hot water is obtained, hot water and combustion gas are respectively utilized by the waste heat supply device and the gas feeder to supply gas, heat and hot water for residents, acetic acid can be used as a biological foliar fertilizer, a biopesticide or a biological bactericide, and tar can be used as an industrial raw material. The integrated conversion, collection and utilization rate of the waste biomass resources approaches 100%.

Description

technical field [0001] The present invention relates to an equipment and method for utilizing waste resources such as industrial organic solid waste and agricultural biomass waste, in particular to a comprehensive conversion utilization equipment and method for pyrolysis and gasification of biomass waste resources mainly composed of crop straws It is also a comprehensive conversion and utilization equipment and method for pyrolysis and gasification of industrial organic solid waste resources. Background technique [0002] my country is a large agricultural country, and a large amount of biomass resources such as crop straw and slag are produced in agricultural production and agricultural product processing. Traditional utilization methods are mainly used as household energy, feed, fertilizer, industrial raw materials and construction materials. With the modernization of agricultural technology and the rapid development of agricultural economy, the rural living standards hav...
