Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a wave cracking gas purification treatment device. Background Art

[0002] The wave cracking process effectively utilizes the characteristics that all organic wastes are organic macromolecules, and organic macromolecules are mainly connected by carbon-carbon single bonds. At the same time, the selective absorption of carbon-carbon single bonds on waves of different frequencies is utilized, and a wave emission source that can be absorbed by carbon-carbon single bonds and has a relatively narrow frequency range is adopted. Through the radiation of waste, the carbon-carbon single bonds in the waste are selectively resonated, thereby breaking the CC bonds and gradually decomposing solid organic macromolecules into small organic molecules. As the decomposition proceeds, small molecular organic matter is evaporated as the system temperature rises. The evaporated matter is cooled by circulating water to become fuel oil, liquefied natural gas, and natural gas that cannot be compressed. This is also a commonly used method for treating pyrolysis gas. However, due to the complexity of waste, the composition of pyrolysis gas will also change accordingly. For example, pyrolysis gas also contains sulfide, carbon monoxide, and carbon dioxide, which cannot be directly prepared into fuel and may have certain toxicity. Therefore, tail gas purification equipment is crucial. Utility Model Content
