Abstract

The invention discloses a continuous sectioned crop straw pyrolysis circulation system which comprises six subsystems, namely a material delivery subsystem, a pyrolysis carbonization subsystem, a finished carbon collection subsystem, a tar collection subsystem, a wood vinegar collection subsystem and a gas collection subsystem, wherein the material delivery subsystem consists of a hydraulic push rod feeding device and a feeding bin; the carbonization subsystem comprises a furnace body and a combustion chamber; the carbon collection subsystem comprises a settling chamber, a screw feeder and a dust separator; the tar collection subsystem comprises a condenser; the straw vinegar fluid collection system comprises a sprayer; and the gas collection subsystem comprises an induced draft fan and a gas storage tank.

Description

technical field [0001] The invention relates to a straw pyrolysis system, in particular to a continuous segmental pyrolysis cycle system for crop straws, in which gas produced by utilization of straws is reused, pyrolyzed, kept warm, and heated and carbonized by segmental temperature control. Background technique [0002] At present, there are several types of carbonization equipment: [0003] 1) Charcoal kiln is the simplest method of biomass pyrolysis and carbonization, and its carbonization cycle is very long. Now, a certain carbonization cycle is shortened by blast heating and other means. However, the carbonization results are quite different. [0004] 2) Mobile carbonization furnace can reduce labor intensity and is greatly affected by seasons. [0005] 3) Natural carbonization furnace, combining traditional craftsmanship and modern machinery manufacturing technology. At present, carbonization furnaces for biochar production generally have shortcomings such as low c...
