Abstract

The invention discloses a biomass pyrolysis system and method through self-sufficient energy. The biomass pyrolysis system comprises a feeding device, a pyrolysis device, a separating and cooling device, an air flue gas component and a generating power component, wherein the pyrolysis device is connected with the feeding device so as to perform pyrolysis on the biomass raw materials; the separating and cooling device is connected with the pyrolysis device so as to receive and separate coke and pyrolysis gas output by the pyrolysis device; the air flue gas component is connected with the separating and cooling device so as to combust the pyrolysis gas and the preheated air and respectively feed the gas back to the feeding device and the pyrolysis device; and the generating power component is connected with the air flue gas component so as to convert the heat of the pyrolysis gas and the preheated air into mechanical energy and supplement the power source of the pyrolysis device and the separating and cooling device. According to the biomass pyrolysis system, the energy of the biomass pyrolysis gas product is subjected to gradient utilization, and the system has the advantages of self-sufficient energy, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of biomass pyrolysis utilization, in particular to an energy self-sufficient biomass pyrolysis system and method. Background technique [0002] my country has 1.48 billion mu of saline-alkali land resources. The development and utilization of deserted saline-alkali land for planting crops and energy plants can make full use of existing land resources, and has important strategic significance for the unified development of rural economy, society and ecological benefits. Among the existing saline-alkali land treatment technologies, the use of biomass coke to improve saline-alkali land and the use of platform fields for salt washing combined with saline-alkali water microalgae cultivation are effective ways to both treat saline-alkali land and develop and utilize biomass energy resources. But to realize these two technologies, the material coke production and the carbon nutrient source required for the growth ...
