Solid waste or biomass high-efficiency pyrolysis oil-producing system

Abstract

The invention discloses a solid waste or biomass high-efficiency pyrolysis oil-producing system. The solid waste or the biomass is charged into a pyrolyzing furnace, wherein the pyrolyzing furnace is internally provided with a thermoelectric couple, and an intelligent temperature controller controls the heating power of an electric stove wire outside a reaction pipe; a pyrolysis volatile component product enters into a semi-coke separation device from an air outlet on the top of the reaction pipe; sequentially, the pyrolysis volatile component enters into at least two levels of condensing device to be condensed; and a large number of non-condensable substances contained in pyrolysis gas continuously passes through a high-voltage electrostatic separation device, wherein the non-condensable pyrolysis oil is collected into a collecting bottle through the high-voltage electrostatic separation device. According to the system provided by the invention, the heat and mass transfer effects of the solid waste and the biomass material in the process of pyrolysis can be preferably enhanced; the volatile component can be preferably overflowed; and the semi-coke product and the gas can be effectively separated from each other, and the productivity and the quality of the liquid diesel oil product can be greatly improved. According to the different feeding varieties of the biomass, the system can obtain more than 10%-15% of the biological oil compared with a general biomass pyrolysis liquefaction process.
