Abstract

The invention relates to a method and a device for pyrolysis of wood tar through microwave. According the method, oxygen-free wood gas is fed into honeycomb activated carbon for being heated, wherein the honeycomb activated carbon is heated to 800-1200 DEG C through the microwave, so that macromolecules in the wood tar is heated and pyrolyzed into micromolecules and further wood gas containing non-caked wood tar. The device includes a microwave heating body in which the honeycomb activated carbon is disposed. A regenerator A is arranged on a gas inlet of the microwave heating body and a regenerator B is arranged on a gas outlet of the microwave heating body. By means of the device and the method, pyrolysis of the wood tar is more complete with catalysis of the honeycomb activated carbon and energy consumption of the pyrolysis is reduced due to recycle of thermal energy in a loop, wherein the pyrolysis itself is free of energy consumption. The wood gas is pyrolyzed in a microwave oven at high temperature under an oxygen-free condition and is high in quality. The pyrolysis techonology is simple and reliable in structure.

Description

technical field [0001] The invention relates to a microwave wood tar cracking method and a device thereof. Background technique [0002] The tar in the wood gas adheres to the pipeline and the wall of the equipment during the operation of the system equipment, causing obstacles to the operation of the equipment and interruption of the production process. It needs to be cleaned frequently, resulting in huge economic losses. Contents of the invention [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a microwave wood tar cracking method and its device, which can not only fully crack wood tar in wood gas, but also can be recycled Heat, reduce energy consumption. [0004] In order to solve the above technical problems, the first technical solution of the present invention is: a microwave wood tar cracking method, which introduces oxygen-...
