Description
Technical field
The utility model relates to Technologies for Recovery of Organic Solvents, particularly relates to a kind of tandem spirit solvent retrieving arrangement.
Background technology
It is a kind of important method of producing modified starch that spirit solvent method produces modified starch, the features such as reaction efficiency is high, reaction is even, non-environmental-pollution that it has.But produce modified starch in the reactor in existing spirit solvent method, the ratio of starch, alcohol consumption is 1:2 ~ 3, immediately the recycle and reuse of spirit solvent is considered, final often production 1 ton of modified starch, need the alcohol consuming 0.3-0.5 ton, therefore produce in modified starch in existing spirit solvent method, there is alcohol recycle efficiency not high, the degree of cleaning of partially recycled spirituous solution are poor the technological deficiency such as directly can not to use.
Produce in modified starch device in existing spirit solvent method has a few cover reactor will adopt a few cover independently solvent recovering system simultaneously usually, and it is intricate that facility investment is many, occupation area of equipment is many, pipeline connects.
Summary of the invention
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of tandem spirit solvent retrieving arrangement, and the degree of cleaning for solving low, the partially recycled spirituous solution of alcohol recycle efficiency in prior art are poor can not directly be used, equipment arranges the technical problems such as complicated.
For achieving the above object and other relevant objects, the utility model provides a kind of tandem spirit solvent retrieving arrangement, comprise: strainer, washing lotion tank, the first condenser 1, second condenser 3, the 3rd condenser 4, liquid collecting tank 2, first vacuum pump 5 and the second vacuum pump 6, strainer is connected one to one with washing lotion tank; Many groups washing lotion tank is connected to the first condenser 1 by form in parallel; First condenser 1 is connected with liquid collecting tank 2 and the second condenser 3; Second condenser 3 is connected with the 3rd condenser 4; 3rd condenser 4 is connected with liquid collecting tank 2, first vacuum pump 5 and the second vacuum pump 6; First vacuum pump 5 and the second vacuum pump 6 are connected to sourdine 7 by form in parallel.
Preferably, described strainer is provided with dust removal by filtration net; Preferred further, described dust removal by filtration net is dust removal by filtration net is anti-electrostatic terylene needled felt or terylene conductive base cloth; The technical requirements of anti-electrostatic terylene needled felt or terylene conductive base cloth is, weight per unit area: 450-800g/m
2, ventilation property: 80-100m
3/ m
2/ S, warp-wise pulling force: 1000-1500N/5*20cm, broadwise pulling force: 1300-1600N/5*20cm, use temperature: < 130 DEG C.
Preferably, washing lotion tank is provided with water film dust removal device.
As mentioned above, the utility model provides a kind of tandem spirit solvent retrieving arrangement, and this device rationally have employed also in equipment connection, the structure design of series connection, reduces Equipments Setting, can use by unit, also can onlinely use.This device by also, the structure design of series connection, such that air-flow flow process is elongated, cooling performance promote, improve 7% by comparing spirit solvent organic efficiency with existing condensing works.
In existing spirit solvent retrieving arrangement, malleation part can collect the 20-40% of spirit solvent input amount, but the alcohol of malleation portion collection, turbid appearance, there is the greasy dirt of vacuum pump, directly can not use, use after needing distillation and concentration to purify, add production cost.By structure design of the present utility model, 3 groups of condensers are all moved on to negative pressure part, substantially increasing negative pressure part can the yield of spirit solvent of direct reuse, extremely low by spirit solvent contained by the malleation part after vacuum pump, therefore by just direct emptying after sound damper, without the need to regathering the residual alcohol of malleation part.
Accompanying drawing explanation
Fig. 1 is shown as the structural representation of the embodiment of tandem spirit solvent retrieving arrangement of the present utility model.
Fig. 2 is shown as the structural representation of the embodiment of existing spirit solvent retrieving arrangement.
Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1.Notice, structure, ratio, size etc. that this specification sheets institute accompanying drawings illustrates, content all only in order to coordinate specification sheets to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionlity or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this specification sheets as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, the utility model provides a kind of tandem spirit solvent retrieving arrangement, comprise: strainer, washing lotion tank, the first condenser 1, second condenser 3, the 3rd condenser 4, liquid collecting tank 2, first vacuum pump 5 and the second vacuum pump 6, strainer is connected one to one with washing lotion tank; Many groups washing lotion tank is connected to the first condenser 1 by form in parallel; First condenser 1 is connected with liquid collecting tank 2 and the second condenser 3; Second condenser 3 is connected with the 3rd condenser 4; 3rd condenser 4 is connected with liquid collecting tank 2, first vacuum pump 5 and the second vacuum pump 6; First vacuum pump 5 and the second vacuum pump 6 are connected to sourdine 7 by form in parallel.
