Reflux oil distribution device in washing section of distillation tower

Abstract

The invention discloses a distillating tower washing section return oil distributor, which comprises a return oil distributor, a filler condensation section, a distribution board, an L-shaped long board, a ring-shaped collection tank, an oil outlet and a filler washing section, wherein the filler condensation section is arranged below the return oil distributor; a distribution board is arranged under the filler condensation section; the L-shaped long board is fixed on the distribution board via bolts, and the ring-shaped liquid collection tank is arranged under the L-shaped long board; the oil outlet is formed in the ring-shaped liquid collection tank; the filler washing section is arranged under the ring-shaped liquid collection tank. According to the invention, the filler washing section return oil can be supplied in the tower, and a set of return oil feeding system is not needed to be additionally arranged, so that the equipment investment is lowered; the height difference between the distribution board and the L-shaped long board can be regulated, and the flux of the return oil can be regulated; a sawtooth shaped lower end surface is arranged on the distribution board, as a result, the filler washing section return oil is uniformly distrusted, and the washing effect is improved; the filler washing section has the effects of washing and rectifying, and improves the rectifying efficiency.

Description

technical field [0001] The invention relates to a vacuum distillation device, in particular to a reflux oil distribution device in the washing section of a distillation tower in petrochemical production. Background technique [0002] In the production process of waste lubricating oil regeneration and extraction of lubricating oil base oil, the waste lubricating oil first removes mechanical impurities and most of the water through sedimentation, and then separates the remaining water through an atmospheric distillation tower; the removal of mechanical impurities and water The material enters the first-stage distillation tower to separate light diesel oil; the material after the first-stage distillation enters the second-stage distillation tower for vacuum distillation, and the distillate oil and distillation residue are separated. For sale, the distilled raffinate is used as fuel. The secondary distillation column is provided with a packing condensation section and a packing...
