Description
Technical field
The utility model relates to the device in furfural production process, particularly a kind of furfural extraction unit.
Background technology
The device that present stage relates to furfural treatment has, and Chinese patent 201020573703.0 discloses a kind of device improving refinement rate of furfural, is mainly made up of comprehensive tower, condenser and knockout etc., and this device main purpose is the refining rate improving furfural; Chinese patent 201120077655.0 discloses a kind of continuous refining device for furfural, mainly be made up of neutralizing tank, dehydrating tower, treating column and link road etc., this device main purpose is the effect realizing continuous treating furfural, this device first goes to neutralize the organic acid in hair aldehyde with alkali lye simultaneously, and then be refined into furfural product, due to in alkali and subtractive process in Na
+meeting and furfural carry out the reaction of health formula, generate furfural sodium, simultaneously Na
+also can and acetic acid reaction, generate sodium acetate, this just causes the generation of loss in Furfural Treating Process and impurity, thus makes the productive rate of furfural low.
Utility model content
Technical problem to be solved in the utility model is, there is provided a kind of technical scheme of furfural extraction unit for deficiency of the prior art, the program can not only realize continuous treating furfural, improves refining rate, can also increase work efficiency, finally reach the object of increasing economic efficiency.
For achieving the above object, the technical scheme taked of the utility model is as follows:
A kind of furfural extraction unit, comprise evaporating kettle, packed tower, overhead condenser, knockout, furfural finished pot, feed pipe, still liquid discharge nozzle, described evaporating kettle, packed tower, overhead condenser and knockout form " mouth " font return-flow structure, and described " mouth " font return-flow structure at least arranges two or more.Packed tower in described each " mouth " font return-flow structure is installed on described evaporating kettle, the top of described packed tower is provided with a condenser, the other end of described condenser connects knockout, the side face port of described knockout is connected with described furfural finished pot, and the bottom interface of described knockout is connected with the side of described packed tower.The bottom of described evaporating kettle is provided with still material discharge nozzle, and described packed tower is provided with a feed pipe away from the side of described knockout.
As improvement of the present utility model: described each " mouth " font return-flow structure is arranged on the both sides of described furfural finished pot symmetrically.
As further improvement of the utility model: described feed pipe, still liquid discharge nozzle form " Http " font structure respectively, the number of described feed pipe and described still liquid discharge nozzle arranges two or more at least respectively, described feed pipe is installed in the top of described packed tower and described condenser, and described still liquid discharge nozzle is installed in the below of described evaporating kettle and described furfural finished pot.
Improve further again as of the present utility model: the number that arranges of described furfural finished pot is one, and the tank mouth of described furfural finished pot is connected with the side face port of described knockout.
Compared with prior art, the utility model furfural extraction unit, adopt overhead reflux technique, evaporating kettle and packed tower (also claiming flash column) go out aldehyde mouth and are connected condenser, knockout, furfural finished pot and finished product delivery outlet in turn by pipeline, also adopt the technical scheme be symmetrical set simultaneously, make furfural extraction unit of the present utility model, first can remove neutralized crude aldehyde with alkali, again it is refined, continuous treating furfural can not only be realized like this, improve refining rate, can also increase work efficiency, finally reach the object of increasing economic efficiency.
