Self-heating vertical axial-flow drum ablative pyrolysis reactor

Abstract

The present invention involves a self -heating vertical axis roller ablation, which is a technical field of renewable energy utilization.Including the shell and the reaction cylinder located inside the shell, there is a shaft inside the reactor, the upper end of the rotating shaft is connected to the inverter motor through the belt, and the speed of the rotation shaft can be adjusted., The raw end of the first -level spiral feeder is connected to the feed end of the second -level spiral feeder, and the raw end of the secondary spiral feeder is connected to the upper part of the reactor.The beneficial effect of the present invention is to improve the efficiency of thermal solution. There is no need to promote the gas and the heating of the heat carrier during the reaction process, which greatly reduces the heating and cooling load of the load.Realize the self -heating process of thermal solution, and fully realize the effective use of energy.Different cone angles can adapt to changes in the size of the material. It can heat up the biomass materials such as powder, granularity and other biomass materials, and better realize gas solid separation and thermal solution of biomass.

Description

technical field [0001] The invention relates to a pyrolysis reaction device, in particular to a self-heating vertical axial flow drum ablation pyrolysis reaction device, which belongs to the technical field of renewable energy utilization. Background technique [0002] Biomass pyrolysis is a technology that thermally decomposes biomass to generate condensable volatile components (bio-oil), non-condensable small molecular gas (non-condensable gas) and solid product biochar in a micro-oxygen or anaerobic atmosphere. The conversion of biomass such as agricultural and forestry wastes into high-value bio-oil is a very promising thermochemical conversion technology. For biomass pyrolysis and liquefaction technology, there are various pyrolysis reactors for biomass pyrolysis and liquefaction to produce bio-oil, but to produce high-quality bio-oil, the choice of biomass pyrolysis reactor form is biomass pyrolysis. The core and key of the device not only requires good heat and mass ...

The problem is that the fluidization air volume is large and the energy loss is large

[0008] The existing patent number is CN201710330591.2, which discloses a new double-rotary biomass pyrolysis liquefaction system, which uses waste heat and flue gas to dry materials, and heats the heat carrier with combustible components of charcoal and non-condensable gas. The heat carrier and materials are evenly distributed in the reaction cylinder. Mixing, pyrolysis reaction occurs, which improves the conversion efficiency of pyrolysis, but lacks a baking device for biomass materials, which reduces the quality of bio-oil or other pyrolysis products
