Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Solid waste or biomass pyrolysis liquefaction technology refers to the direct pyrolysis of biomass under the conditions of medium temperature of about 500°C, high heating rate and extremely short gas residence time (about 2s). Liquid oil is obtained by rapid cooling.

[0022] Such as figure 1 As shown, the solid waste or biomass is roughly or regularly crushed (the crushing scale depends on the pyrolysis reaction device), and then fed into the pyrolysis furnace 1. The furnace type can be selected from various current fixed bed, fluidized bed and other furnace types. The pyrolysis furnace 1 can adopt heating methods such as external heating or internal heating, and the purge gas is an inert gas such as nitrogen. An electric furnace wire 22 is arranged outside the pyrolysis reactor 1 as a heat source and also serves as a heat p...

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.

Description

technical field [0001] The invention belongs to the technical field of resources and environment, and in particular relates to a high-yield and high-quality pyrolysis oil production technology and process of solid waste or biomass. Background technique [0002] Due to the decreasing of fossil energy and the severe environmental pollution it brings, clean renewable energy is increasingly becoming the most ideal substitute for fossil energy, and the development of renewable clean energy will be the key to the sustainable development of human beings. Biodiesel produced by pyrolysis and liquefaction of solid waste and biomass, as an alternative renewable clean energy, has become one of the research and development hotspots in the field of new energy. [0003] The conversion of solid waste and biomass into higher quality and versatile energy products and chemicals through thermochemical processing has attracted special attention worldwide. Pyrolysis refers to the process in whic...
