Abstract
The utility model discloses a crude biodiesel feeding device for a flash tower. The crude biodiesel feeding device for the flash tower comprises a feeding pump (1), a conveying pipeline, a valve and a feeding pipe (3) and is characterized by also comprising barrel type quickly open filters (2) and a nozzle (4), wherein the feeding pump (1), the barrel type quickly open filters (2) and the feeding pipe (3) are connected with the valve sequentially through the conveying pipeline; two barrel type quickly open filters (2) are arranged in parallel; the nozzle (4) is a spiral nozzle, is arranged at the tail end of the feeding pipe and is in threaded connection with the feeding pipe (3); a spiral channel of the nozzle is smooth and is tapered; and a nozzle orifice with a jet angle is arranged at the tail end of the spiral channel. By the crude biodiesel feeding device for the flash tower, the feeding pipe is difficult to block; the distributivity of the crude biodiesel on a flash tower distribution disc is high; the heat transfer area is large; the gasification time is short; and the flash evaporation effect is good.
Description
One, technical field
The utility model relates to the coarse biodiesel flashing tower feeding unit 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 coarse biodiesel flashing tower fractionation by distillation of lower boiling (vapour point) according to them, just can reach standard compliant biofuel goods.Coarse biodiesel flashing tower feeding unit is the flashing tower important component part, and whether this apparatus structure rationally directly influences the flash distillation effect of flashing tower, thereby has influence on the normal operation of Distallation systm, and then influences biofuel quality and production energy consumption.The coarse biodiesel flashing tower feeding unit of prior art generally is directly inputted on the distributing disc or through the feed-pipe that is drilled with aperture by feed-pipe and is ejected on the distributing disc; Not enough below this device exists:
A, the Liquid Distribution property is poor when directly being input to coarse biodiesel on the distributing disc by feed-pipe, and adopts when being drilled with the feed-pipe of aperture then feed-pipe easy blocking and cleaning mediation inconvenience.
B, liquid surface area and heat interchanging area are less, and the flash distillation effect is relatively poor, influence biofuel quality and production energy consumption.
Three, summary of the invention
The purpose of the utility model provides a kind of feed-pipe that makes and is difficult for obstruction, the coarse biodiesel coarse biodiesel flashing tower feeding unit that distributivity is good on the flashing tower distributing disc, heat transfer area is big, vaporization time is short, flash distillation is effective.
For realizing above purpose, the utility model coarse biodiesel flashing tower feeding unit comprises fresh feed pump, bucket formula fast-opened filter, feed-pipe and nozzle, is connected fresh feed pump, bucket formula fast-opened filter and feed-pipe successively through transport pipe and valve; Said bucket formula fast-opened filter is established two and is the parallel connection layout; Said nozzle is a spiral nozzle, and it is terminal and be threaded with feed-pipe to be located at feed-pipe, and the nozzle helical channel is slick and sly and descending, and end has the spout of a spray angle.
Said structure coarse biodiesel flashing tower feeding unit has following characteristics: the one, be provided with the bucket formula fast-opened filter that can switch mutually, and be used for removing organic impuritys such as the most of fatty acid soaps of coarse biodiesel; The 2nd, the spiral nozzle helical channel is slick and sly and descending, and end has the spout of a spray angle, after coarse biodiesel is through the spiral nozzle ejection, is solid cone shaped and evenly sprays down.
Said structure coarse biodiesel flashing tower feeding unit has following effect:
A, flashing tower are provided with two bucket formula fast-opened filters of switch operating mutually outward, can effectively remove the suspension organic impurity, can not shut down cleaning, and be easy to use.
B, adopt clog-free spiral nozzle, be solid cone shaped evenly spray down, jeting effect is good, surface-area is big, heat interchanging area is high, flash distillation is effective.
Four, description of drawings
Accompanying drawing is the utility model coarse biodiesel flashing tower feeding unit 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 feeding unit comprises fresh feed pump 1, bucket formula fast-opened filter 2, feed-pipe 3 and nozzle 4, is connected fresh feed pump 1, bucket formula fast-opened filter 2 and feed-pipe 3 successively through transport pipe and valve; Said bucket formula fast-opened filter is established two and is the parallel connection layout; Said nozzle 4 is a spiral nozzle, and it is terminal and be threaded with feed-pipe to be located at feed-pipe, and the nozzle helical channel is slick and sly and descending, and end has the spout of a spray angle.
During operation, open the vacuum system that is connected with low-boiling-point substance outlet 5-1, after flashing tower 5 reaches the certain vacuum degree; With fresh feed pump 1 coarse biodiesel is sprayed in the flashing tower 5 through spiral nozzle 4 by feed-pipe 3 after organic impurity is removed in 2 worries of bucket formula fast-opened filter more continuously, liquid is repeatedly redistributed, increase heat transfer area through distributing disc 5-2; Shorten vaporization time; Low-boiling-point substances such as methyl alcohol are under high vacuum state, and the step-down vaporization is resolved, and 5-1 is drawn out of through the low-boiling-point substance outlet; 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 5-3.
Claims (1)
