Problems solved by technology

Tar and acetic acid are discharged together with the washing water, which can not be used effectively, but also leads to water source and soil pollution
At the same time as biomass pyrolysis, with the generation of a large amount of heat, the high-temperature combustible gas carrying heat needs to be cooled before it can be used. During the washing and cooling process, the heat is often discharged together with the washing water, which cannot be effectively used and is wasted

Abstract

The invention discloses a comprehensive waste biomass resource transformation and utilization system and method through pyrolysis and gasification. The system comprises pyrolysis equipment, a gas supply device, multifunctional heat exchange equipment, and a residual-temperature heater, wherein a gas channel of the multifunctional heat exchange equipment is connected with the pyrolysis equipment and the gas supply device respectively; and a condensate water channel of the multifunctional heat exchange equipment is connected with the residual-temperature heater. The method comprises the following steps that: raw materials, namely biomass wastes, are sent into the pyrolysis equipment, and high-temperature pyrolysis is performed on the raw materials to form mixed gas containing combustible gas, tar gas, acetic acid gas and water vapour; and the mixed gas is sucked into the multifunctional heat exchange equipment, and heat exchange is performed on the mixed gas to isolate combustible gas, tar-acetic-acid mixed liquid and hot water. The hot water and the combustible gas are respectively utilized by the residual-temperature heater and the gas supply device to supply gas, heat, and hot water for residents in a concentrated way; acetic acid can serve as biological foliar fertilizer, biological insecticide, or biological bactericide; and the tar can serve as an industrial raw material. According to the system and method, the comprehensive waste biomass resource transformation and utilization rate reaches 100%, and secondary pollution is avoided.

Description

technical field [0001] The present invention relates to a system and method for utilizing waste resources such as industrial organic solid waste and agricultural biomass waste, in particular to a system and method for comprehensive conversion and utilization of biomass waste resources pyrolysis and gasification mainly based on crop straws. The method is also a system and method for comprehensive conversion and utilization of pyrolysis 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 stalks and chaff residues 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 the agricultural economy, the rural li...
