Abstract
The utility model discloses a distilling dehydration device which comprises a distillation still (1), a condenser (2), a water segregator (3), a moisture receiving tank (4), a valve (5), a distilling pipe (6) and a moisture delivery pipe (7), wherein the distilling pipe (6) is connected onto the distillation still (1); the distilling pipe (6) is connected with the upper end of the condenser (2); the lower end of the condenser (2) is connected with the upper end of the water segregator (3); the lower end of the water segregator (3) is connected with the valve (5) and then connected with the distillation still (1); the middle outlet of the water segregator (3) is connected with the moisture delivery pipe (7) and then connected with the moisture receiving tank (4). According to the distilling dehydration device, the dehydration speed is high; the dehydration is complete; the consumption of raw materials is reduced and the loss of intermediate products is reduced; the pollution to workshops and damage to employees in the workshops are reduced; the distilling dehydration device is suitable for industrialized production.
Description
Technical field
The utility model provides a kind of reflux dewatering device, belongs to chemical industry, pharmaceutical equipment field.
Background technology
Azithromycin is 15 ring azilide class antibiotic, and it is take erythromycin as raw material, obtains through oximate, Beckmann rearrangement, reduction and methylation reaction.Azithromycin after reduction reaction will could generate azithromycin through methylation reaction, because reduction reaction is carried out in water, and methylation reaction carries out in organic phase, if and have while methylating water to exist, can affect the carrying out of reaction, there is more impurity to generate, so will be dried except water treatment solvent.Traditional handicraft is before methylating, to add drier, solvent is dewatered, but this technique will consume a large amount of drier, and drier is not recyclable, causes waste and contaminated environment, also can cause the loss of solvent and workman's injury simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of distillation dehydration device is provided, and the moisture in organic solvent is removed by separated, and simple to operate, production efficiency is high, and utilization rate of equipment and installations is high, and economizes in raw materials and the energy.
The utility model is achieved in that 1 is distillation still, the 2nd, and condenser, the 3rd, water knockout drum, the 4th, moisture receiving tank, the 5th, valve, the 6th, distillation cascade, the 7th, moisture delivery line.
In distillation still (1), connect distillation cascade (6), distillation cascade (6) is connected with condenser (2) upper end, and condenser (2) lower end is connected with water knockout drum (3) upper end, after water knockout drum (3) lower end is connected with valve (5), then is connected with distillation still (1); After water knockout drum (3) central exit is connected with moisture delivery line (7), then be connected with moisture receiving tank (4).
The distillation dehydration device of said structure, simple to operate, production efficiency is high, and utilization rate of equipment and installations is high, and economizes in raw materials and the energy, has avoided solvent loss and workman's injury.
Accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model.
In accompanying drawing 1: the 1st, distillation still, the 2nd, condenser, the 3rd, water knockout drum, the 4th, moisture receiving tank, the 5th, valve, the 6th, distillation cascade, the 7th, moisture delivery line.
the specific embodiment
Below in conjunction with accompanying drawing 1, concrete structure of the present utility model is described.
As shown in Figure 1, the distillation dehydration device of the utility model, it is by distillation still (1), condenser (2), water knockout drum (3), moisture receiving tank (4), valve (5), distillation cascade (6), moisture delivery line (7) composition.
In distillation still (1), connect distillation cascade (6), distillation cascade (6) is connected with condenser (2) upper end, and condenser (2) lower end is connected with water knockout drum (3) upper end, after water knockout drum (3) lower end is connected with valve (5), then is connected with distillation still (1); After water knockout drum (3) central exit is connected with moisture delivery line (7), then be connected with moisture receiving tank (4).
In the time carrying out distillation dehydration operation, first condenser (2) cooling water to be opened, valve (5) is closed; And then distillation still (1) is passed into Steam Heating, solvent vapo(u)r enters condenser (2) by distillation cascade (6), condensate liquid flows into water knockout drum (3), in the time that water knockout drum (3) central exit has moisture to flow out, flow is opened and controlled to valve (5), make the interface of the middle organic phase of water knockout drum (3) and water be positioned at water knockout drum central exit below, upper strata water flows in moisture receiving tank (4) through central exit and moisture delivery line (7).While separating without moisture in water knockout drum, dewater complete.
Claims (1)
1. a distillation dehydration device, is characterized in that, it is by distillation still (1), condenser (2), water knockout drum (3), moisture receiving tank (4), valve (5), distillation cascade (6), moisture delivery line (7) composition;
In distillation still (1), connect distillation cascade (6), distillation cascade (6) is connected with condenser (2) upper end, and condenser (2) lower end is connected with water knockout drum (3) upper end, after water knockout drum (3) lower end is connected with valve (5), then is connected with distillation still (1); After water knockout drum (3) central exit is connected with moisture delivery line (7), then be connected with moisture receiving tank (4).
