Foreign flavor removing method and device in dimmer acid distillation technique

Abstract

The invention relates to a process used for preparing dimer acid by vegetable oil acid, in particular to a method and a device used for eliminating the peculiar smell in the distillation process of the dimer acid. The technical proposal is that the method used for eliminating the peculiar smell in the distillation process of the dimer acid comprises an atomization reactor which is internally provided with a high-pressure nozzle plate, the lower surface of which is uniformly provided with high pressure nozzles; high pressure water passes by the high pressure nozzles on the high pressure nozzle plate so as to form high pressure water mist; the mixed gas during the distillation process of the vegetable oil acid sufficiently mixes with the high pressure atomized water in the opposite direction; the light distillate dust deposits owning to increased weight after encountering the atomized water; the purified gas is exhausted out of the atomization reactor; and the method and the device have the beneficial effects that the high pressure atomized water in the atomization reactor is sufficiently mixed with the peculiar smell, the light distillate dust deposits owning to increased weight after encountering the atomized water, and then the purified gas is exhausted out of the atomization reactor, thus achieving the object of eliminating the peculiar smell.

Description

1. Technical field: [0001] The invention relates to a process for preparing dimer acid from vegetable oleic acid, in particular to a method and device for eliminating peculiar smell in the distillation process of dimer acid. 2. Background technology: [0002] At present, in the vegetable oleic acid process, in the distillation process for producing dimer acid, the mixed gas discharged by vacuuming contains a kind of light distillate dust, which is scattered into the air and floats with the wind, causing air pollution and An unpleasant, pungent odor. 3. Contents of the invention: [0003] The purpose of the present invention is to address the above-mentioned defects in the prior art, and to provide a method and device for eliminating odor in the dimer acid distillation process, using high-pressure water mist and mixed gas to generate water vapor atomization and mixing, and the light fraction dust in the mixed gas After encountering atomized water, the weight will be increa...
