The raw material ethanol proportioning device comprises an industrial ethanol gauge tank (1), a recovered ethanol gauge tank (2), a proportioning pump (5), a mixed raw material ethanol storage tank (6), a raw material ethanol feeding pump (7), an industrial ethanol charging pipeline (9), a recovered ethanol charging pipeline (10), a primary water intake pipeline (12), an ethanol-removing preheater pipeline (13), a fermented ethanol distillation head fraction charging pipeline (11), a fermented ethanol distillation head fraction gauge tank (3), a fermented ethanol distillation head fraction filter (4), and a charging filter (8).The utility model provides the raw material ethanol proportioning device in the process for preparing the acetaldehyde by utilizing the oxidation, which can fully utilize precious ethanol resources in the firstcut, reduces the production cost of the ethanol, enhances the market competition capacity and can prolong the service life of a catalyst.
Description
Technical field
The utility model is the proportioner that a kind of oxidation of ethanol prepares feed ethanol in the acetaldehyde technology.Belong to the device improvement for preparing acetaldehyde by oxidation.
Background technology
In fermentative production of ethanol technology, the heads that distillation workshop section collects is called as the foreshot, and the ethanol content among the foreshot is up to more than 90%.But the cost of the technical standard that reaches industrial alcohol owing to its separation is purified is higher, the way processing foreshot that most producers sell outside adopting at a low price.Cause the ethanol among the foreshot not to be fully used, cause the wasting of resources.
Oxidation of ethanol method of the prior art is produced in the acetaldehyde technology, reaction is about 84% batching ethanol with feed ethanol, after adopting about 70% recovery ethanol of 95% industrial alcohol and native system recovery to mix by a certain percentage, enter preheater, enter oxidation furnace then and participate in oxidative dehydrogenation.Still there are the following problems:
1. the ethanol raw material cost awaits further reduction, to improve the acetaldehyde competition capability.
2. catalyst is shorter service life.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of ethanol resource that can either make full use of the preciousness among the foreshot, can reduce the acetaldehyde production cost again, improve its market competitiveness, and the oxidation of ethanol that can prolong catalyst service life prepares the proportioner of feed ethanol in the acetaldehyde technology.
The purpose of this utility model can reach by following measure:
Oxidation of ethanol of the present utility model prepares the proportioner of feed ethanol in the acetaldehyde technology, comprise the industrial alcohol measuring tank 1 that is connected with pipe fitting by pipeline, reclaim alcohol meter measuring tank 2, dosing pump 5, mixed material ethanol storage tank 6, feed ethanol feeding engine 7, industrial alcohol feeding line 9, reclaim ethanol feeding line 10, a water enters pipeline 12, removes ethanol preheater pipeline 13, it is characterized in that also comprising:
A. distill heads filter 4 by pipeline and the interconnective successively fermenting alcohol distillation of pipe fitting heads feeding line 11, fermenting alcohol distillation heads measuring tank 3, fermenting alcohol;
B. enter pipeline 12 and the charging filter 8 that goes ethanol preheater pipeline 13 to be connected by pipeline and pipe fitting and feed ethanol feeding engine 7, a water.
Oxidation of ethanol of the present utility model prepares the proportioner of feed ethanol in the acetaldehyde technology, oxidation of ethanol in the prior art prepares in the commercial plant of acetaldehyde, has added a. and has distilled heads filter 4 by pipeline and the interconnective successively fermenting alcohol distillation of pipe fitting heads feeding line 11, fermenting alcohol distillation heads measuring tank 3, fermenting alcohol; B. enter pipeline 12 and the charging filter 8 that goes ethanol preheater pipeline 13 to be connected by pipeline and pipe fitting and feed ethanol feeding engine 7, a water.Successful solution the ethanol among the foreshot of the prior art can not be fully used, cause the wasting of resources; And the ethanol raw material cost in the acetaldehyde production awaits further reduction, to improve two technical problems of acetaldehyde competition capability.
The impurity that fermenting alcohol distillation heads and other raw materials are brought the oxidation reaction stove into has been removed in the dual setting of fermenting alcohol distillation heads filter 4 and charging filter 8, has prolonged the service life of catalyst, has further reduced the production cost of acetaldehyde.
The disclosed oxidation of ethanol of the utility model prepares the technical scheme of the proportioner of feed ethanol in the acetaldehyde technology, can produce following good effect compared to existing technology:
1. a kind of ethanol resource that can either make full use of the preciousness among the foreshot is provided, can have reduced the acetaldehyde production cost again, improved its market competitiveness, and the oxidation of ethanol that can prolong catalyst service life prepares the proportioner of feed ethanol in the acetaldehyde technology.
2. the ethanol that has successfully solved among the foreshot of the prior art can not be fully used, and causes the problem of the wasting of resources.
3. the ethanol raw material cost in the acetaldehyde production reduces, and has improved the acetaldehyde competition capability.
4. prolong the service life of catalyst, reduced the production cost of acetaldehyde.
