An energy-saving and environmentally friendly biomass fuel pyrolysis device

Abstract

The invention relates to the field of biomass pyrolysis equipment, specifically an energy-saving and environment-friendly biomass fuel pyrolysis device, which includes a device main body, a slag removal device is fixedly installed on the upper end of the device main body, and a pyrolysis chamber is fixedly installed inside the device main body. A rotating rod is installed movable inside the chamber, and the first agitating plate is fixedly installed on the outside of the rotating rod. The lower end of the rotating block is set in a conical shape, so that when the flue gas in the pyrolysis chamber moves from the outlet pipe to the inside of the slag removal device, it can first Contact with the inclined surface at the lower end of the rotating block to change the moving direction of the flue gas, and then block the dust and impurities in the flue gas through the filter residue plate outside the rotating block. The inclined surface can be used to apply force to the filter residue plate to rotate the rotating block, and at the same time, the filtered dust and impurities can move upward along the slope of the filter residue plate and concentrate on the top of the filter residue plate, so as to achieve environmental protection and avoid blockage of the filter residue plate.

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
