Desulfurization system for methanol production process

The utility model provides a desulfurization system for a methanol production process, which comprises a purifier, a pre-desulfurization tank, a preheater, a primary converter, a medium-temperature desulfurization tank, a secondary converter and a medium-temperature oxidizer, and the inlet ends and the outlet ends of the purifier, the pre-desulfurization tank, the preheater, the primary converter,the medium-temperature desulfurization tank, the secondary converter and the medium-temperature oxidizer are sequentially communicated through pipelines. The first-stage converter and the second-stage converter are the same in structure, the first-stage converter comprises a filter, conversion pipes and a hydrogen supply device, the bottom face of the filter is communicated with the multiple conversion pipes at equal intervals, and the bottom ends of the conversion pipes are connected with the hydrogen supply device. According to the desulfurization system for the methanol production process,the coke-oven gas is guid
