Technical Field
[0001] The utility model belongs to the technical field of pyrolysis and gasification equipment, and specifically relates to a biomass fluidized bed pyrolysis and gasification equipment. Background Art
[0002] A biological fluidized bed is a structure that uses smaller, inert particles such as sand, activated carbon, and coke as carriers. The carrier surface is covered with a biofilm. Wastewater flows upward at a constant velocity, fluidizing the carrier particles. The wastewater then flows upward through the sand bed, causing the carrier layer to flow. This increases the contact area between the biofilm and the wastewater per unit time, providing sufficient oxygen, and utilizing the boiling state of the filler to enhance the biological wastewater treatment process. Pyrolysis and gasification refers to the process in which, in the absence or absence of oxygen, the macromolecules of organic components in wastewater break down, producing small molecules of gas, tar, and residue.
[0003] As a kind of biomass raw material, domestic waste has many types and complex components. Pouring domestic waste into pyrolysis and gasification equipment for treatment can not only achieve the harmlessness, reduction and resource utilization of waste, but also effectively overcome the dioxin pollution problem caused by the incineration of domestic waste. However, the existing biomass fluidized bed pyrolysis and gasification equipment adopts a rotary sealing component at the discharge point when in use, which is prone to residue accumulation and extrusion during the discharge process, which is not conducive to the smooth discharge of the residue after pyrolysis and gasification treatment into the biomass fluidized bed.
