Abstract
A methyl ester extraction device relates to a methyl ester extraction device in equipment for producing natural fatty alcohol and is designed for mainly resolving problems that the existing methyl ester extraction device is uneven in contact between steam condensed water and methyl ester and is poor in separating effect. The methyl ester extraction device comprises a crude methyl ester tank, a methyl supplying pump, a feeding preheater, an extraction tower and a separator, a three-way pipe A is additionally arranged on a pipe connecting the crude methyl ester tank with the methyl ester supplying pump, a branched pipe of the three-way pipe A is connected with a hot water tank containing steam condensed water, and a three-way pipe B is further connected between the three-way pipe A and the methyl ester supplying pump, a branched pipe of the three-way pipe B is connected with a mixing groove through an extraction pump, a discharge opening of the mixing groove is connected with a discharge pipe of the crude methyl ester tank via a pipe, and flow adjusting valves are respectively arranged on a branched pipe between the three-way A and the hot water tank and a pipe between the methyl ester supplying pump and the feeding preheater. The methyl ester extraction device has the advantages that the methyl ester and the steam condensed water are sufficient in contact and fine in separation effect.
Description
Technical field:
The utility model relates to a kind of methyl esters extraction plant of producing in the natural fatty alcohol equipment.
Background technology:
The steam condensate of existing methyl esters extraction plant adds from the extraction tower top, and it is inhomogeneous that shortcoming is that steam condensate contacts with methyl esters, and inferior separating effect causes in the product methyl esters to contain glycerol liquor and exceeds standard.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of steam condensate and contacts with methyl esters evenly, the methyl esters extraction plant of good separating effect.
Above-mentioned purpose is achieved in that same as the prior art is that it also comprises thick methyl esters jar, thick methyl esters jar has discharge nozzle to link to each other with the feed preheater bottom through the methyl esters charging pump, the low-pressure steam import is arranged on the feed preheater, the top of feed preheater has pipeline to link to each other with the bottom of extraction tower, also has separator, there is dividing plate that the lower space of separator is divided into two portions in the separator, the top of extraction tower has pipeline to link to each other with a side of separator, this side bottom has pipeline to link to each other with the extraction tower bottom, the opposite side of separator has pipeline to be connected through the smart methyl esters storage tank of methyl esters pump with the outside, and the extraction tower bottom has pipeline to be connected through the glycerol liquor storage tank of glycerine water pump with the outside; Different with above-mentioned prior art is: set up a threeway A on thick methyl esters jar and pipeline that the methyl esters charging pump links to each other, the arm of threeway A is connected with the hot-water cylinder that steam condensate is housed, between threeway A and methyl esters charging pump, be connected a threeway B again, the arm of threeway B is connected with tempering tank through the extraction pump, the discharge port of tempering tank has pipeline to be connected with the discharge nozzle of thick methyl esters jar, and flow control valve is being housed respectively on the arm between threeway A and the hot-water cylinder and on the pipeline between methyl esters charging pump and the feed preheater.
The utility model has the advantages that: steam condensate mixes by the high speed shear of extraction pump impeller with methyl esters, methyl esters fully contacts with steam condensate, glycerol liquor separates rapidly with methyl esters after entering extraction tower, and the glycerol liquor content in the methyl esters is significantly reduced, and can reach the technic index requirement.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
With reference to accompanying drawing, it comprises thick methyl esters jar 1, thick methyl esters jar has discharge nozzle to link to each other with feed preheater 4 bottoms through methyl esters charging pump 3, the low-pressure steam import is arranged on the feed preheater, the top of feed preheater has pipeline to link to each other with the bottom of extraction tower 5, also has separator 6, there is dividing plate that the lower space of separator is divided into two portions in the separator, the top of extraction tower has pipeline to link to each other with a side of separator 6 dividing plates, this side bottom has pipeline to link to each other with the extraction tower bottom, the opposite side of separator has pipeline to be connected through the smart methyl esters storage tank of methyl esters pump 8 with the outside, and the extraction tower bottom has pipeline to be connected through the glycerol liquor storage tank of glycerine water pump 7 with the outside; On thick methyl esters jar 1 and pipeline that methyl esters charging pump 3 links to each other, set up a threeway A11, the arm of threeway A is connected with the hot-water cylinder 9 that steam condensate is housed, between threeway A and methyl esters charging pump 3, be connected a threeway B12 again, the arm of threeway B is connected with tempering tank 10 through extraction pump 2, the discharge port of tempering tank 10 has pipeline to be connected with the discharge nozzle of thick methyl esters jar, on the arm between threeway A11 and the hot-water cylinder 9 and on the pipeline between methyl esters charging pump 3 and the feed preheater 4 flow control valve is being housed respectively.
Working process:
With extraction pump 2 will from the thick methyl esters of thick methyl esters jar 1 with squeeze into tempering tank 10 from the steam condensate of hot-water cylinder 9 by a certain percentage by flow control, play circulation by the extraction pump and make water and thick methyl esters thorough mixing, be transported in the feed preheater 4 through methyl esters charging pump 3 and flow control valve again after tempering tank top discharge pipe enters the discharge nozzle of thick methyl esters jar.Methyl esters and water mixture are heated to about 80 ℃ by low-pressure steam in feed preheater after, extracting and separating is carried out in the bottom that enters extraction tower 5, methyl esters after the extraction overflows to the separator 6 from cat head, methyl esters after separator 6 is settlement separate is delivered in the smart methyl esters storage tank with methyl esters pump 8, and glycerol liquor then returns the extraction tower bottom.
