Description
Technical field
The utility model relates to a kind of rectifying device, specifically a kind of continuous rectification apparatus for the butanols dehydration.
Background technology
Butanols is as a kind of comparatively general solvent, and through being usually used in chemical synthesis, the moisture technological requirement that do not meet of the butanols after use, can't be used by direct circulation.Therefore must carry out moisture butanols processed, can recycle after qualified, reach the purpose reduced costs.Traditional butanols dewatering process, mainly utilize batch fractionating tower, and this kind of method cycle is long, the moisture butanols front-end volatiles of extraction are many, labour intensity is large, and repetitive operation is expected, heats up, lowers the temperature many as thrown in, heat up in a steamer before rectifying and repeat to return throwing, consume energy high, loss of material is many, needs the artificial frequent reflux ratio of regulating, and produces unstable, energy consumption is also high, and cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of and can make butanols dehydration continued operation, avoid repeating throwing in material, repeat the cooling that heats up, utilize flowmeter and control valve etc. to reach the continuous rectification apparatus for the butanols dehydration that Automatic continuous is produced.
The utility model addresses the above problem taked technical scheme: a kind of continuous rectification apparatus for the butanols dehydration, be provided with moisture butanols tank, pump, heat exchanger, rectifying column, the rectifying tower reactor, condenser, heat exchanger, qualified butanols tank, Liquid level adjusting valve, flowmeter, draining valve, it is characterized in that: described moisture butanols tank is provided with pump, the top pipeline of pump is provided with flowmeter and is connected with heat exchanger, heat exchanger is connected with rectifying column to the right, the rectifying column below is connected with the rectifying tower reactor, the rectifying column upper end is provided with condenser, the condenser below is connected with draining valve with rectifying column respectively by two flowmeters, rectifying tower reactor left side is provided with Liquid level adjusting valve, Liquid level adjusting valve upwards is connected with heat exchanger, heat exchanger upwards is connected with heat exchanger, heat exchanger is connected with qualified butanols tank.
The utility model is owing to taking said structure, easy and simple to handle, and equipment investment is few, can greatly enhance productivity, and reduces the butanols loss, reduces wastewater flow rate, and running cost is reduced greatly, is particularly suitable for the manufacturing enterprise that the butanols use amount is large.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, be labeled as: 1. moisture butanols tank, 2. pump, 3. flowmeter, 4. heat exchanger, 5. rectifying column, 6. rectifying tower reactor, 7. condenser, 8. flowmeter, 9. flowmeter, 10. heat exchanger, 11. qualified butanols tanks, 12. Liquid level adjusting valves, 13. draining valves.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the utility model relates to a kind of continuous rectification apparatus for the butanols dehydration, be provided with moisture butanols tank 1, pump 2, heat exchanger 4, rectifying column 5, rectifying tower reactor 6, condenser 7, heat exchanger 10, qualified butanols tank 11, Liquid level adjusting valve 12, flowmeter 3, 8 and 9, draining valve 13, it is characterized in that: described moisture butanols tank 1 is provided with pump 2, the top pipeline of pump 2 is provided with flowmeter 3 and is connected with heat exchanger 4, heat exchanger 4 is connected with rectifying column 5 to the right, rectifying column 5 belows are connected with rectifying tower reactor 6, rectifying column 5 upper ends are provided with condenser 7, condenser 7 belows are connected with draining valve 13 with rectifying column 5 respectively with 9 by flowmeter 8, rectifying tower reactor 6 left sides are provided with Liquid level adjusting valve 12, Liquid level adjusting valve 12 upwards is connected with heat exchanger 4, heat exchanger 4 upwards is connected with heat exchanger 10, heat exchanger 10 is connected with qualified butanols tank 11.
When the utility model is used, butanols utilizes pump 2 through flowmeter 3 and heat exchanger 4 from moisture butanols tank 1, enter rectifying column 5, rectifying tower reactor 6 heats to guarantee that moisture enters condenser 7, moisture butanols is back in rectifying column 5 again through flowmeter 8, moisture in condenser 7, is discharged through draining valve 13 from the continuous extraction of tower top through flowmeter 9.Moisture butanols produces moisture qualified butanols after above rectifying, falls into rectifying tower reactor 6, and the butanols in rectifying tower reactor 6 keeps moisture qualified and balance liquid level, by the control of Liquid level adjusting valve 12, makes qualified butanols continuously to top discharge.Now, qualified butanols is high temperature, in order to take full advantage of its thermal source, moisture butanols before utilizing heat exchanger 4 and entering heat exchanger 4 carries out heat exchange, the moisture butanols entered is heated up, make qualified butanols cooling, the circulating water cooling in recycling heat exchanger 10, be that qualified butanols drops to normal temperature, final qualified butanols enters qualified butanols tank 11.
