Device for reducing content of methyl alcohol in silver-method methanol process

The utility model relates to a device for reducing content of methyl alcohol in a silver-method methanol process, and belongs to the technical field of chemical industry production. The technical scheme is as follows: the device comprises an air filter (1), a blower (2), a methanol evaporator (3), a ternary heater (4), an oxidation reactor (5) and an absorption tower (6) which are sequentially arranged, wherein a concentration evaporator (7) is arranged between an outlet of the oxidization reactor and an inlet of the absorption tower; and a vacuum groove (8) is formed in a methanol liquid extracting port at the bottom of the absorption tower. According to the device, the heat recovery efficiency of a system is improved while the temperature of the inlet of the absorption tower is reduced; the load of a water cooler of the absorption tower is reduced, the consumption of cooling water is reduced, 100 percent of classification recycling of residual liquid is realized, and the recycled methanol has no phenomenon
