Description

A kind of novel steam distillation experimental provision

Technical field

The utility model relates to a kind of steam distillation experimental provision.

Background technology

Steam distillation operation is that steam is fed insoluble or is insoluble in water but has in the mixture of certain volatile organic substance; Make this organic matter when being lower than 100 ℃ along with steam distills together, separate and the purpose of purification organic compound thereby reach.

Steam distillation experimental provision commonly used comprises water vapor generation device and two parts of distilling apparatus, mainly by steam generator, bursting tube, steam delivery line, T type pipe, emulsion tube, tongs, plug, steam ingress pipe, distillate steam delivery line, round-bottomed flask with long neck, condenser pipe, adapter with connect device such as liquid bottle and form.Mainly there is following technical problem when utilizing this type of steam distillation experimental provision operation:

1) glass and other devices are many, circuit is long, mounting or dismounting are loaded down with trivial details, poor air-tightness, the heat waste of package unit are big;

2) for preventing that round-bottomed flask with long neck (being cucurbit) from because of water vapor condensation ponding, outside the thermal source of the steam generator that dewaters, usually need add a thermal source in addition, two thermals source of a covering device like this, energy consumption is high, and heat utilization efficiency is low;

3) the steam distillation time longer, usually need stop distillation procedure and add water, loaded down with trivial details time-consuming; If add water through bursting tube, the one, safe caliber is little, adds the water inconvenient operation, and the 2nd, influence the security of device;

4) through opening the tongs that T type pipe connects steam emptying is stopped distillation procedure, perhaps close tongs steam is imported cucurbit when carrying out steam distillation, have to be prone to the danger of being scalded by steam.

Summary of the invention

The utility model technical problem to be solved provide a kind of simple in structure, easy to operate, energy consumption is low, heat utilization efficiency is high, can shorten distillation time, safe and practical steam distillation device.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of steam distillation experimental provision comprises going up bottle, produce following bottle of steam, the threeway of y type, spherical condensating tube, elbow, condenser west tube, adapter, connecing liquid bottle and bursting tube of dress sample.The said bottle of going up is partially submerged into down bottle; Said last bottle separates with the said following bottle of diapire (being said following bottle roof) by said last bottle; The said bottle of going up connects through two ports that place the said y type threeway outside it with following bottle, connects with spherical condensating tube behind the valve of the 3rd port connection in the threeway of said y type again; Said following bottle of steam that produces directly heats the diapire (being said following bottle roof) of going up bottle, and then sample is heated; Said following bottle of steam that produces imports the said bottle of going up through said y type threeway, and the said sample of going up in the bottle is carried out steam distillation, and cut imports condenser west tube through elbow, and the cooling back is flowed into by adapter and connects the liquid bottle; Said following bottle of steam that produces imports spherical condensating tube through said y type threeway, is back to said following bottle after the cooling.

A port of said y type threeway is equipped with rotatable valve, and another port connects the bend pipe at 10 ° ~ 80 ° of angles.

A port in the threeway of said y type is connected with said following bottle the first half, derives steam; The bend pipe that another port connects directly inserts said bottom of going up bottle, steam is imported carry out steam distillation in the sample; The 3rd port that valve is housed connects behind the spherical condensating tube and atmosphere again.

Said 1/8 ~ 2/3 of the bottle of going up embeds following bottle, said following bottle through the thermal source heating, it is said that to go up that bottle fired with following bottle of the two quilt be an integral body, two in the threeway of said y type stimulate the menstrual flow the standard ground respectively with said upward bottle and following bottle connect.

Said 1/8 ~ 2/3 of the bottle of going up embeds following bottle, and said following bottle is heated by thermal source, said upward bottle, following bottle and y type threeway three are fired is an integral body.

Compared with prior art, the utility model has the advantages that:

1) bottle of going up of dress sample is partially submerged into following bottle that produces steam, at first can shorten the distance between steam generator and the cucurbit, the minimizing heat waste, and two bottles of shared thermals source up and down, energy-conservation and improved the utilization rate of thermal source; Next following bottle steam that produces directly heat the diapire of going up bottle, thereby the sample in the last bottle is heated, this both can be before steam distillation in preheating sample, the adjusting bottle the water yield, also can prevent in the still-process on bottle because of water vapor condensation ponding;

2) going up bottle connects through the threeway of y type with following bottle; On the one hand because the logical valve that is equipped with in the threeway of y type; Can steam import be gone up bottle through the turning knob valve-off and carry out steam distillation, steam is imported spherical condensation tube reflux and stop steam distillation thereby perhaps open valve, more than easy to operate; Steam can not leak, and has improved the security of experimental implementation; On the other hand because the backflow effect of spherical condensating tube; In the operating process of steam distillation, can add water directly continuous, safely from the mouth of pipe of spherical condensating tube upper end; Dryout to prevent to produce following bottle of steam, can also further regulate the speed that adds water through the opening degree of valve, guarantee that water speed is not too fast because of adding, hypervolia influence following bottle continuously upwards bottle supply with a steam; Can shorten the distillation procedure time, improve distillation efficiency.
