Energy-saving and environment-friendly biomass fuel pyrolysis device

Abstract

The invention relates to the field of biomass pyrolysis equipment. The invention relates to an energy-saving and environment-friendly biomass fuel pyrolysis device. The device comprises a device body,a deslagging device is fixedly mounted at the upper end of the device body, a pyrolysis cavity is fixedly mounted in the device body, a rotating rod is movably mounted in the pyrolysis cavity, a first stirring plate is fixedly mounted on the outer side of the rotating rod, the lower end of a rotating block is conical, when flue gas in the pyrolysis cavity moves from a gas outlet pipe to the interior of a slag removal device, the moving direction of smoke can be changed by contacting with the lower-end inclined surface of the rotating block, dust and impurities in the flue gas are blocked through a residue filtering plate on the outer side of the rotating block, the filter residue plate is arranged in an inclined L shape, so that when flue gas makes contact with the filter residue plate, an acting force can be applied to the filter residue plate through the inclined plane to enable the rotating block to rotate, meanwhile, filtered dust impurities can move upwards along the inclined plane of the filter residue plate to be concentrated at the upper end of the filter residue plate, the environment-friendly effect is achieved, and the filter residue plate is prevented from being blocked.

Description

technical field [0001] The invention relates to the field of biomass pyrolysis equipment, in particular to an energy-saving and environment-friendly biomass fuel pyrolysis device. Background technique [0002] Biomass pyrolysis (also known as pyrolysis or cracking), usually refers to the process in which biomass is heated and heated to cause molecular decomposition to produce coke, condensable liquid and gas products in an oxygen-free or low-oxygen environment. An important form of utilization, biomass rapid pyrolysis liquefaction technology can obtain higher yields of bio-oil, compared with raw material biomass, the energy density of bio-oil is greatly improved, and the transportation cost is greatly reduced, which is conducive to further centralized large-scale refining , which is of great significance for the efficient conversion and high-value utilization of biomass. [0003] However, most of the existing biomass pyrolysis devices are not equipped with environmentally f...

Problems solved by technology

[0003] However, most of the existing biomass pyrolysis devices are not equipped with environmentally friendly emission devices, so that the flue gas generated by pyrolysis is directly discharged to the outside, causing pollution to the environment. The part of the material particles burned into ash outside is stripped and discharged, which affects the efficiency of internal combustion of biomass particles, which in turn affects the efficiency of biomass pyrolysis
