Heavy alcohol treatment device and use method

The invention discloses a heavy alcohol treatment device and a use method, and belongs to the technical field of chemical production, the heavy alcohol treatment device comprises a wiped film evaporator, a primary separator, a secondary separator, a heavy alcohol delivery pump, a condenser, a vacuumizing system, a vacuumizing condensate tank and a vacuumizing condensate delivery pump. According to the method, part of light components such as ethylene glycol and diethylene glycol in the heavy alcohol are recycled, the content of salt in fed materials is high, and if the fed materials are not treated, the salt is easy to accumulate on a pipe wall to cause blockage of a pipeline, so that the problem that the pipeline is easy to block due to high salt content in the heavy alcohol is solved, and the production cost is reduced. Part of ethylene glycol and diethylene glycol in the heavy alcohol are recovered, so that the economic benefit is improved, and the loss of product materials of the device ...
