Biomass thermoelectricity-based straw three-element clean co-production and low-carbon circulation device thereof

Abstract

The invention discloses biomass thermoelectricity-based straw three-element clean co-production and a low-carbon circulation device thereof. The biomass thermoelectricity-based straw three-element clean co-production and the low-carbon circulation device thereofare characterized in that the biomass thermoelectricity is adopted, agricultural and forestry waste biomass fuel is burned to simultaneously produce and output heat energy, electric energy, plant ash and flue gas, and all or part of the heat energy, the electric energy, the plant ash and the flue gas are supplied to the straw three-element clean co-production and served as a straw three-production base; the low-carbon circulation device mainly comprises an agricultural and forestry waste biomass thermoelectricity device, a straw clean preparation raw material device, a primary coagulation hydrolysis hemicellulose device, an alcohol preparation hemicellulose and alcohol collection device, a plant ash preparation low dosehydrolysate device, a secondary low dosehydrolytic lignin device, a secondary slurry preparation cellulose device, a flue gas and secondary hydrolysate treatment residual alkaline device and a flue gas vaporization liquid phase preparation lignin device. The biomass thermoelectricity-based straw three-element clean co-production has the advantages that the biomass thermoelectricity-based straw three-element clean co-production is innovated, the agricultural and forestry waste biomass resources can be refined, classified and utilized, the straw utilization are high-valued, industrialized and large-scale, a low-carbon production and circular economic mechanism is formed, and the sustainable development of agricultural and rural environment management is further promoted.

Description

technical field [0001] The invention relates to the fields of utilization of biomass resources, comprehensive utilization of five straws, biomass thermoelectricity, circular economy, agricultural and rural environment management, etc., and specifically relates to biomass thermoelectric-based straw three-element clean co-production and a low-carbon cycle device. [0002] technical background [0003] Basic characteristics of straw: first, the main components are 35-50% cellulose, 15-40% hemicellulose, and 15-35% lignin; second, the hemicellulose contains more wood than wood. [0004] It is reported that the total amount of crop straw in our country reaches 800 million tons every year, only a small part is taken out of the field for utilization, and most of them are broken up by machinery and returned to the field, causing serious soil diseases and insect pests because they cannot be degraded in time, so despite the government's introduction of Stricter environmental management...

Problems solved by technology

[0012] However, the current agricultural and forestry waste biomass thermal power industry, due to factors such as the increasing gap in domestic policy-based electricity price subsidies and the decline in policy-based electricity price subsidies for new energy sources such as photovoltaic and wind power, its development growth rate has slowed down significantly; therefore, for The agricultural and rural environmental governance situation of up to 1,000 agricultural counties across the country constitutes a negative impact
