Device and method for utilizing biological substance for monobed self-heating oil manufacturing with coke separation function

Abstract

The invention provides a device and a method for utilizing a biological substance for monobed self-heating oil manufacturing with a coke separation function. The device comprises a combustion system, a pyrolysis and coke separation system, as well as an air distribution and entrainment system, wherein a guide tube is positioned in the center; a combustion zone is positioned above the guide tube; a pyrolysis zone is positioned outside the guide tube. The method comprises the following steps: through a conical second dipleg, a heat carrier is entrained into the guide tube; the entrained heat carrier is heated in the guide tube and the combustion zone; a redirector is utilized for changing the flow direction, so as to form a fountain state; a combustion product slips into a first dipleg, and then enters the pyrolysis zone to heat the biological substance. The device and the method have the advantages that the coke is collected by combusting non-condensable gas, and automatic coke separation is achieved, so that high-performance coke can be obtained; the whole process can be realized in a monobed, so that the device is compact in structure and suitable for a movable platform, and can be placed in the fields for biological substance processing; through the conical second dipleg, the blow-by phenomenon can be effectively prevented.

Description

technical field [0001] The invention relates to the field of utilization of biomass resources, in particular to a single-bed self-heating biomass oil production device and method with coke separation. Background technique [0002] Energy is the driving force for human survival and development. At present, the world's main energy sources are non-renewable fossil fuels such as coal, oil, and natural gas. As a result, on the one hand, the extensive use of fossil fuels has caused serious environmental pollution problems, such as the greenhouse effect, acid rain, and smog. etc.; on the other hand, the increasingly depleted fossil fuels seriously threaten human energy security and sustainable development. Therefore, the search for renewable energy has become a matter of great concern to countries all over the world. [0003] Biomass energy is a kind of renewable energy. Biomass energy has many advantages such as renewable, clean, low-carbon, low in harmful substances, and rich i...

Problems solved by technology

However, many current technologies cannot meet this demand. For example, most biomass pyrolysis reactors have a double-bed structure, and the circulation of particles is not easy to control, and the volume is large, and the investment is large, so it is difficult to meet the mobile requirements; Southeast University's Invention patent "Single-bed self-heating pyrolysis gasification combustion reactor and pyrolysis gasification combustion method", authorized announcement number CN101245264B, discloses a single-bed method for separating pyrolysis and combustion, the invention The entrainment holes at the bottom are relatively simple, the reaction process is too sensitive, there is a certain phenomenon of blow-by gas, and the coke produced by the reaction is burned, and the pyrolysis non-condensable gas is collected.
