Description

technical field [0001] The invention relates to a multistage eddy current electromagnetic ultrafine dust flue gas processor for methanol cracking reaction, belonging to the technical field of methanol cracking reaction. Background technique [0002] At present, the chloride ions brought in by garbage power generation and coal-fired boiler flue gas will corrode stainless steel, fluoride ions will corrode glass (instrument), and the alkaline substances added in desulfurization will also corrode steel. However, conventional exhaust gas treatment devices cannot effectively control the above three harmful substances. [0003] In addition, there are a large number of designs for conventional factory flue gas, but for hydrogen production by reforming methanol, there is no special comprehensive tail gas treatment device for hydrogen removal and purification, and ultrafine particle removal. Exhaust gas contains many impurities, such as carbon monoxide, ultra-fine solid catalyst part...
