Embodiment Construction

[0035] An embodiment will be given below to further describe the present invention in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0036] like figure 1 Shown, a kind of preparation technology of biomass oil comprises the following steps:

[0037] (1) crushing the biomass material into powder particles with a particle size less than 2mm;

[0038] (2) drying the obtained material particles at 100-200°C;

[0039] (3) subjecting the dried material particles to a cracking reaction at 420-650° C. under anoxic conditions;

[0040] (4) cooling the cracked product once to 200-240°C;

[0041] (5) Separating the cooled pyrolysis product, removing ash and residual oil in the product;

[0042] (6) Carry out secondary cooling to 15-30 ℃ to the product after removing ash and residual oil, collect biomass oil;

[0043] (7) cooling the uncondensed gas produced in (6) to -5-5°C for three times, and collecting low bo...

Abstract

The invention discloses a technology for preparation of biotic oil with dissimilar components using biomass including crop straw and its devices. The biotic materials produce the biotic oil by disintegrating process, dehydrating process, split process, multi-stage condensing process and disintegrating process and the devices install reducing mechanism for materials, drier installation, feed gear, cracking unit for bulk, multi-stage condensing unit, debonding unit and collecting device corresponding to every process. The invention can be used in preparing biotic oil with a large industrial scale, in which the heavy leavings and solid carbon powder mixed with ashes can be used as fuels of furnace; the elementary biotic oil can directly be used in direct-combustion system including oil-burning boiler and direct-combustion central air-conditioning, which can substitute gasoline and diesel as combustion engine fuel by refining; the biotic oil with low-boiling point and high-quality can substitute liquefied petroleum gas as domestic fuel.

Description

technical field [0001] The invention relates to a process and a device for the industrial production of high-quality biomass oil by rapid pyrolysis, and the process and device can be used for the industrialized large-scale production of biomass oil. Background technique [0002] The main body of today's energy structure is still oil, natural gas, and coal. However, fossil fuels such as oil and natural gas are non-renewable resource reserves are decreasing day by day. In recent years, energy shortages have appeared to varying degrees around the world; The formation of the greenhouse effect and acid rain will bring unpredictable damage to the ecology. With the development of economy and society, people's demand for energy will continue to increase, and the development of renewable energy is an inevitable choice to promote the sustainable development of the national economy. Among them, biomass energy is a form of energy in which solar energy is stored in organisms in the for...
