Device for improving yield of dimethyl sulfide

The utility model discloses a device for improving the yield of dimethyl sulfide, which is characterized in that a mixed gas pipeline is connected with a fused salt preheater, a vaporizer is connected with the fused salt preheater, the fused salt preheater is connected with a fused salt tank, and the fused salt tank is connected with a sulfide reactor through a feeding pump. And the fused salt preheater is also connected with a methanol absorption tower feeding pipe. And the thioether reactor is connected with the fused salt preheater. When the dimethyl sulfide production device is used for producing dimethyl sulfide, reaction heat release is utilized, liquid methanol is vaporized, the utilization rate of resources is increased, the feeding amount of the methanol is increased, the yield of the dimethyl sulfide is increased, and meanwhile, the loss of equipment is also reduced. 本实用新型专利公开了一种提高二甲基硫醚产量的装置，混合气管道与熔盐预热器连接，汽化器与熔盐预热器连接，熔盐预热器与熔盐槽连接，熔盐槽经过上料泵与硫醚反应器连接。熔盐预热器上还连接有甲醇吸收塔进料管。硫醚反应器与熔盐预热器连接。采用本实用新型的装置生产二甲基硫醚，不仅利
