Problems solved by technology

[0002] In the furfural production process, the furfural is refined. First, it needs to use the different boiling points of the components to dehydrate under vacuum conditions, and then use the principle of furfural-water to form an azeotrope for further dehydration. Through continuous reflux, to obtain qualified furfural Therefore, the water content of furfural is an important indicator for evaluating the grade of furfural. The lower the water content, the higher the grade of furfural. By increasing the reflux ratio and prolonging the refining production time, the existing processes can be improved to reduce the water content of furfural. , but the loss of furfural in this process will increase, which will affect the refining rate and increase the production cost

Abstract

The invention discloses a furfural dehydration device, comprising a furfural storage tank and a dehydration unit. The furfural dehydration device is characterized in that the dehydration unit comprises an aldehyde extraction pump, a dehydrator and a raw material storage tank; the dehydrator comprises a dehydration tower 1 and a dehydration tower 2; the dehydration tower 1 and the dehydration tower2 are internally filled with inorganic filler layers; the furfural storage tank is connected with the aldehyde extraction pump through a pipeline; the aldehyde extraction pump communicates with the lower end part of the dehydration tower 1 through a pipeline; the upper end part of the dehydration tower 1 communicates with the lower end part of the dehydration tower 2 through a pipeline; and the upper end part of the dehydration tower 2 communicates with the raw material storage tank through a pipeline. The furfural dehydration device of the invention has the advantages of reasonable structureand convenient use; in virtue of physical dehydration and absorption of an inorganic filler, the moisture of furfural can be simply and efficiently reduced, and the content of furfural can be increased; and a filler regenerating device is utilized to enable the inorganic filler for dehydration to be repeatedly regenerated and recycled, so the product quality of furfural is improved while production cost is effectively reduced.

technical field [0001] The invention relates to the technical field of furfural production, in particular to a furfural dehydration device. Background technique [0002] In the furfural production process, the furfural is refined. First, it needs to use the different boiling points of the components to dehydrate under vacuum conditions, and then use the principle of furfural-water to form an azeotrope for further dehydration. Through continuous reflux, to obtain qualified furfural Therefore, the water content of furfural is an important indicator for evaluating the grade of furfural. The lower the water content, the higher the grade of furfural. By increasing the reflux ratio and prolonging the refining production time, the existing processes can be improved to reduce the water content of furfural. , but the loss of furfural in this process will increase, which will affect the refining rate and increase the production cost. Contents of the invention [0003] The technical...
