Rotary downdraft type straw pyrolytic carbon gas co-production equipment

Abstract

The invention discloses rotary downdraft type straw pyrolysis carbon-gas co-production equipment which comprises a pyrolysis cylinder, a carbon discharging device and a bracket for supporting the pyrolysis cylinder and the carbon discharging device, the pyrolysis cylinder comprises an upper-section cylinder body, a middle-section cylinder body and a lower-section cylinder body, the middle-section cylinder body can rotate by taking a cylinder axis as a center, a material pressing device is arranged at the top of the middle-section cylinder body, and a stirring rod and a gas inlet rod are arranged on the inner wall of the middle-section cylinder body; the charcoal discharging device comprises a conical rotary cylinder, a spiral charcoal conveying plate and a spiral charcoal discharging cylinder; the conical rotary cylinder is arranged at the bottom of the lower-section cylinder body, the spiral charcoal conveying plate is fixedly connected into the conical rotary cylinder, a water inlet cavity is formed in the bottom of the conical rotary cylinder and connected with the water tank through a water conveying pipe, and the bottom of the water inlet cavity is communicated with a feeding port of the spiral charcoal discharging cylinder; according to the rotary downdraft straw pyrolysis carbon gas co-production equipment, the phenomena of slagging, bridging and arching in the pyrolysis and conveying process of materials can be solved, and the carbon discharging sealing performance and stability of a system are greatly improved.

Description

technical field [0001] The invention relates to the technical field of pyrolysis equipment, in particular to a rotary down-suction type straw pyrolysis charcoal gas co-production equipment. Background technique [0002] At present, the working principle of the existing downdraft pyrolysis equipment is as follows: the material enters the pyrolysis reactor through the feeder, when the material reaches a certain height, the feeding is stopped, and the pyrolysis starts after ignition. When the pyrolysis progresses to a certain extent, the generated biochar is discharged through the charcoal discharge device; the pyrolysis gas is discharged through the exhaust port of the equipment. Patent No. CN105505469A mentions a downdraft fixed bed gasification steam power generation co-generation device, including a gasification system and a power generation system. The gasification system includes feeding device, primary air outlet, secondary air outlet, feeder, grate, etc. The power gene...
