Description

1. Technical field

[0001] The invention relates to a device for cracking tar contained in combustible gas produced by biomass gasification or dry distillation, in particular to a high-temperature cracking method and device for biomass gas tar. 2. Background technology

[0002] At present, the combustible gas produced by biomass gasification or dry distillation contains a large amount of tar, and the use of this type of gas is greatly limited due to the lack of effective and feasible removal methods. Generally, coarse filtration methods such as water washing and filtration are used, and the decoking rate is low, and the effect of gas purification is difficult to meet the actual use requirements. In addition, the tar from the coarse filtration of the gas contains too many impurities and cannot be reused, which also brings secondary pollution to the environment. 3. Contents of the invention

[0003] The purpose of the present invention is to provide a high-temperature pyroly...
