A Biomass Pyrolysis Production Liquid Fuel Cogeneration Biochar System

Abstract

A novel biomass pyrolysis production of liquid fuel co-generation biochar system, which belongs to the field of renewable energy utilization technology, includes a spiral reactor, and the spiral reactor is connected to a biomass feeder. It is characterized in that it also includes a blast furnace, and the blast furnace is connected to slag The slag granulator is connected to the spiral reactor through a flow control valve. The upper part of the slag granulator is provided with a slag inlet and a gas outlet, and the lower part is provided with a slag outlet. It also includes a high-speed motor connected to the rotating shaft , an arc-shaped turntable is arranged on the top of the rotating shaft, and a rotating scraper is arranged at the bottom, which cooperates with the slag outlet, and a nozzle air duct is arranged under the arc-shaped turntable. The invention realizes the heat recovery and utilization of the high-temperature slag, fully utilizes the heat energy of the high-temperature slag, and performs pyrolysis and liquefaction of biomass, and has good economic and social benefits.

Description

technical field [0001] The invention relates to a novel biomass pyrolysis production liquid fuel cogeneration biochar system, which belongs to the technical field of renewable energy utilization. Background technique [0002] Biomass pyrolysis liquefaction technology is an effective way to utilize biomass energy, and its product is mainly bio-oil, accompanied by by-product pyrolysis residual carbon and a small amount of gas. On the one hand, bio-oil can be further refined to obtain high value-added chemicals, which can also be used as fuel for engines; on the other hand, residual carbon can be used as bio-fertilizer to improve soil structure, and can also be further processed to obtain carbon black, which can be used as tire additives use. At present, the main thermal cracking liquefaction devices mainly include fluidized bed reactors, circulating fluidized bed reactors, fixed bed reactors, ablation reactors, rotating cone reactors, etc., and the above reactors basically us...

Problems solved by technology

Blast furnace slag waste has a lot of heat. At present, the blast furnace slag is generally quenched to generate hot steam for heating, and the rest is wasted in vain. At the same time, the moisture content of blast furnace slag is as high as 10%. must be dried, and still consume a certain amount of energy

Finally, for the water slag system, the workload of power consumption and system maintenance is also very large
