Abstract
The utility model discloses a dealcoholizing device for biodiesel fuel via adopting methyl esterification. The dealcoholizing device comprises a conveying pump (1), a feeding check valve (2), a flash tower (3) with a plurality of layers of tower inside distributing trays (32) and tower inside tower plates (33), a visual window (4), a discharging check valve (5), a methanol condenser (6) and a vacuum device, wherein an outlet of the conveying pump is connected with the feeding check valve (2) via a pipeline and then is connected with an inlet of the flash tower; an outlet of low-boiling-point substances at the top of the flash tower is sequentially connected with the visual window (4) and the methanol condenser (6) via a pipeline; and a discharging port at the bottom of the flash tower is connected with the discharging check valve (5) via a pipeline. The dealcoholizing device provided by the utility model has the advantages that effective dealcoholization can be realized before fatty acid methyl ester enters into the next process and the settlement of glycerin and dissolved soap is not influenced, and has the characteristic that the dealcoholization is quick and highly-efficient.
Description
One, technical field
The utility model relates to the dealcoholization device in the organic Chemicals production unit, particularly biodiesel oil methyl esterizing production unit.
Two, background technology
Utilize in waste animal vegetable oil production biofuel (fatty acid methyl ester) production process, must use a kind of boiling point and be 63.5 ℃ lower boiling industrial raw material methyl alcohol; In the esterification synthetic reaction process, for improving the transformation efficiency of biofuel product, methyl alcohol is excessive recycling; After the esterification building-up reactions is accomplished, there is a large amount of methyl alcohol in the crude fatty acid methyl ester, must remove, just can carry out follow-up distillation production.Existing dealcoholysis technology generally adopts divides material heat temperature raising, stirring, methanol vapor under vacuum state from the way that removes, and this technological shortcoming is: owing to have glycerine (USP Kosher) and dissolving soap in the thick ester, methyl alcohol is produced package action; Making a part of methyl alcohol to vaporize removes; Influence the dealcoholysis effect, and be unfavorable for the sedimentation of glycerine and dissolving soap, brought very big burden for follow-up distillation process; Influence output, restricted industrial scale.
Three, summary of the invention
But the purpose of the utility model be to provide a kind of before fatty acid methyl ester gets into subsequent processing effective elimination methyl alcohol and do not influence glycerine and the settled biodiesel oil methyl esterizing dealcoholization device of dissolving soap, no matter this device is interrupted dealcoholysis or continuous dealcoholysis all has fast, the characteristics efficiently moved.
For realizing above purpose, the utility model biodiesel oil methyl esterizing dealcoholization device comprises transferpump, charging vacuum breaker, is with the flashing tower of interior distributing disc of plate column and Ta Nei column plate, looks handleless cup, discharging vacuum breaker, methanol condenser and vacuum unit; The transferpump outlet is through connecing the flashing tower inlet behind the pipe connection charging vacuum breaker, low-boiling-point substance outlet in flashing tower top connects through pipeline successively looks handleless cup and methanol condenser, and flashing tower bottom discharge mouth picks out the material vacuum breaker through pipeline.
Adopt said structure biodiesel oil methyl esterizing dealcoholization device; In the process of flash distillation dealcoholysis; Crude fatty acid methyl ester is because the effect of pumping, the tearing effect of distributing disc and the suction function of vacuum of transferpump; Three bursts of actings in conjunction of making a concerted effort are damaged glycerine and the parcel of dissolving soap to methyl alcohol, and methyl alcohol and low component substance are removed more easily; Glycerine also can shorten with the dissolving settlement separate time of soap in the simultaneously thick ester, and is settlement separate more thorough, helps follow-up distillation production; By vacuum unit power is provided, reaching the effect of the gaseous substance that removed low components such as methyl alcohol in the flow medium rapidly, and does not take man-hour, the production efficiency in this workshop, device place there is not influence.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 biodiesel oil methyl esterizing dealcoholization device synoptic diagram.
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 biodiesel oil methyl esterizing dealcoholization device comprises transferpump 1, charging vacuum breaker 2, is with the flashing tower 3 of multilayer distributing disc 32, looks handleless cup 4, discharging vacuum breaker 5, methanol condenser 6 and vacuum unit; The transferpump outlet is through connecing the flashing tower inlet behind the pipe connection charging vacuum breaker 2, low-boiling-point substance outlet in flashing tower top connects through pipeline successively looks handleless cup 4 and methanol condenser 6, and flashing tower bottom discharge mouth picks out material vacuum breaker 5 through pipeline.
During operation, the open vacuum system is after flashing tower reaches the certain vacuum degree; With transferpump 1 crude fatty acid methyl ester bifurcation road behind unidirectional charging vacuum breaker 2 is pumped into from both sides, flashing tower 3 top, distributing disc 32 uniform distribution in tower form the falling film type fluid from top to bottom to the interior column plate 33 of tower; Thick ester is owing to the variation of air pressure, and under the state of vacuum, methyl alcohol reaches low component substance boiling point lowering; Form gas phase; After liquid barrier 31 foam removals, extract out from flashing tower 3 tops by vacuum system,, form the recycling of liquid phase storing to receiving tank through looking handleless cup 4 to condensing surface 6 abundant condensation liquefactions; Back down discharging vacuum breaker 5 spools behind hydrops groove 34 hydrofuls of thick ester to the flashing tower bottom after dealcoholysis separates and be expelled to subsider, continue settlement separate; After flash distillation finished, charging vacuum breaker 2 was shut feed inlet and outlet automatically with discharging vacuum breaker 5, prevents the flash system vacuum breaker, is beneficial to the carrying out of intermittent operation single flash dealcoholysis at present.
Use behind the utility model biodiesel oil methyl esterizing dealcoholization device methyl alcohol to remove amount more and be about the 50-60L/ still; Amount to and contain alcohol amount and be about about 0.4%/still; Thick ester contains pure rate and is stabilized between 0.6-0.8%/still, and dealcoholysis or continuous dealcoholysis have all realized fast, the purpose of efficient operation no matter be interrupted.
