Abstract
The utility model discloses a crude biodiesel flash tower, comprising a tower body (1), a crude biodiesel feeding pipe (2), a distribution plate (3), a biodiesel outlet (4), a baffle plate (5) and a low-boiling-point substance outlet (6), wherein the low-boiling-point substance outlet (6) is connected with a vacuum system; the upper part of the distribution plate (3) is composed of multiple layers of cross-strike-shaped sieve plates; a multi-layer structure, which is composed of multiple layers of V-shaped (with the bottom open) column plates and reversed V-shaped column plates, is arranged below the sieve plates, wherein the column plates are combined in alternating way. The crude biodiesel flash tower disclosed in the utility model can rearrange the crude biodiesel in the flash tower for multiple times. The utility model has characteristics of big heat transmission area, short evaporation time and good flash evaporation effect.
Description
One, technical field
The utility model relates to the coarse biodiesel flashing tower in organic the Chemicals production unit, particularly biodiesel production facility.
Two, background technology
Owing to contain small amount of methanol, glycerine, fatty acid soaps, short chain fatty acid methyl esters and other impurity in the coarse biodiesel; Must have than this characteristics process flashing tower fractionation by distillation of lower boiling (vapour point) according to them, just can reach standard compliant biofuel goods.The coarse biodiesel Distallation systm is the visual plant system of production of biodiesel; Flashing tower wherein is one of major equipment in the coarse biodiesel Distallation systm; Whether this apparatus structure rationally directly influences the flash distillation effect of flashing tower; Thereby have influence on the normal operation of Distallation systm, and then influence biofuel quality and production energy consumption.The coarse biodiesel flashing tower of prior art generally is made up of tower body, coarse biodiesel feed-pipe, biofuel outlet, distributing disc, traverse baffle and low-boiling-point substance outlet, also has not establish distributing disc.Because being " one " type column plate multilayer, this distributing disc is provided with or the setting of " ∧ " type column plate multilayer, not enough below this flashing tower exists:
A, for the flashing tower of not establishing distributing disc; Coarse biodiesel sprays with droplet-like in tower after feed-pipe gets into flashing tower, and coarse biodiesel is only once distribution of experience in tower, so liquid surface area and heat interchanging area are less; The flash distillation effect is relatively poor, influences biofuel quality and production energy consumption.
B, for the flashing tower that is provided with distributing disc; Coarse biodiesel flows to or is ejected on the column plate of distributing disc in the flashing tower through feed-pipe; Liquid is through the redistribution of multilayer column plate, though improve heat interchanging area to a certain extent, liquid surface area or liquid flow are less; Influence heat interchanging area, make the flash distillation effect undesirable.
Three, summary of the invention
The purpose of the utility model provides the coarse biodiesel flashing tower that a kind of coarse biodiesel can repeatedly redistribute, heat transfer area is big, vaporization time is short, flash distillation is effective in flashing tower.
For realizing above purpose; The utility model coarse biodiesel flashing tower comprises tower body, coarse biodiesel feed-pipe, distributing disc, biofuel outlet, traverse baffle and low-boiling-point substance outlet; Low-boiling-point substance outlet connects vacuum system, and to be multilayer "-" shape sieve plate, sieve plate below replace the multilayered structure of be combined into for multilayer "/" shape column plate and " ∧ " shape column plate on said distributing disc top.
Adopt said structure coarse biodiesel flashing tower, coarse biodiesel flows to or is ejected into the flashing tower distributing disc through feed-pipe, and through several sieve plates, liquid is droplet-like and flows from top to down, carries out preliminary flash distillation; Through several "/" and " ∧ " type column plate, liquid is mobile from top to down with S type form and shaped liquid film, passes through different column plates liquid is repeatedly redistributed then; Improve the Liquid Distribution homogeneity; Increase surface-area and heat interchanging area, shorten vaporization time, improve the flash distillation effect.In addition, this coarse biodiesel flashing tower is made simple, and cost is low, and is easy to maintenance, is easy to promote.
Four, description of drawings
Accompanying drawing is the utility model coarse biodiesel flashing tower structural representation.
Five, embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Shown in the accompanying drawing; The utility model coarse biodiesel flashing tower device comprises tower body 1, coarse biodiesel feed-pipe 2, distributing disc 3, biofuel outlet 4, traverse baffle 5 and low-boiling-point substance outlet 6; Low-boiling-point substance outlet connects vacuum system, and said distributing disc is the two-layer four-layer structure that replaces be combined into for "-" shape sieve plate, its below for "/" shape column plate and " ∧ " shape column plate from top to bottom.
During operation, the open vacuum system after flashing tower reaches the certain vacuum degree, imports coarse biodiesel in the flashing tower through feed-pipe 2 imports with pump continuously.At first distribute through the first layer sieve plate; Liquid is droplet-like and flows to second layer sieve plate and carry out flash distillation; Distribute once more through second layer sieve plate, liquid is droplet-like and flows on the trilaminar "/" type column plate, and this moment, liquid was in the middle of shaped liquid film flows to by the edge; Flow to " ∧ " type column plate center of the 4th layer again, liquid film flows to the edge by the center again; Through different column plates liquid is repeatedly redistributed; Increase heat transfer area, shorten vaporization time, low-boiling-point substances such as methyl alcohol are under high vacuum state; The step-down vaporization is resolved; Be drawn out of through low-boiling-point substance outlet 6, reach with biofuel and separate purpose, the material that removes behind the low-boiling-point substance such as methyl alcohol is discharged from biofuel outlet 4.
Claims (1)
1. coarse biodiesel flashing tower, it comprises tower body (1), coarse biodiesel feed-pipe (2), distributing disc (3), biofuel outlet (4), traverse baffle (5) and low-boiling-point substance outlet (6), low-boiling-point substance outlet (6) connection vacuum system; It is characterized in that: said distributing disc (3) top is multilayer "-" shape sieve plate, and sieve plate below replaces the multilayered structure of be combined into for multilayer "/" shape column plate and " ∧ " shape column plate.
