Abstract

The invention relates to an integrated utilizing technology for agricultural waste and in particular relates to an integrated converting and utilizing co-production method for agricultural waste. The integrated converting and utilizing co-production method comprises the following steps: 1. collecting and processing raw materials; 2. carrying out pyrolysis on the raw materials: generating biochar and high-temperature mixed gas; 3. converting the high-temperature mixed gas: converting the high-temperature mixed gas into wood tar, wood vinegar and fuel gas; 4. manufacturing fertilizers; 5. refining fuel oil: converting the wood tar into biofuel oil and wood pitch; 6. purifying the fuel gas: purifying the fuel gas into clean fuel gas; and 7. converting the fuel gas: respectively sending the biofuel gas into a gas generator, a gas supply pipe network and a heat boiler to covert the biofuel gas into heat energy and electricity energy. The agricultural waste can be converted by multiple levels and are combined to be utilized to obtain straw carbon, fuel gas, heat energy, electricity energy, fertilizers, fuel gas and the like. The use ratio of the agricultural waste reaches 100%. The problem that the agricultural waste is stacked and burnt disorderly can be solved, the pollution problem caused by using chemical fertilizers and pesticides for a long time can be solved, and the problem of utilizing energy, fertilizer and oil in rural areas also can be solved.

Description

technical field [0001] The invention relates to a technology for comprehensive utilization of agricultural waste, in particular to a method for comprehensive conversion, utilization and joint production of agricultural waste. Background technique [0002] Our country is stepping into a modern society. my country's population accounts for 20% of the world's total population. The proven coal resources account for only 11% of the world's reserves, crude oil accounts for only 2.4%, and natural gas accounts for only 1.2%. The per capita resource share is less than half of the world's average level. Oil is only 1 / 10. Since 1993, my country has become a net importer of energy. With the rapid development of my country's economy and the improvement of people's living standards, the "China New Energy and Renewable Energy White Paper" issued by the State Planning Commission in 1999 predicted that my country's per capita energy consumption will reach about 2.38t in 2050, although only ...
