NOVELTY - This utility new type relates to one a pyrolysis gasification tar multistage circulation filtering collecting device, belonging to the biomass use technology field. This device comprising in series between the pyrolysis gasification device and water-cleaning and de-dusting device, cooling device and pneuma storage device, the cooling device and the pneuma device set with draught fan connected with a filter screen filtering device, carbon absorbing filtering device and a graphene film filter between the water-cleaning and de-dusting device and cooling device. After using this utility new type, through the pyrolysis gas circulation of cooling water due to the multiple filter and the very pure, storage used for heat generation or a centralized gas supply, a burn fully, without pollution of clean energy.
