Example Embodiment

[0047] Example 1

[0048] Taking a 100 g coal sample as an example, the extraction experiment was carried out with the ultrasonic continuous extraction device of the present invention.

[0049] Open the stopper of the spare feed port 1-2, add 100 g of coal sample and 600 mL of acetone reagent from this port to sample bottle 1; open the stopper of the solvent feed port 5-1, and add 400 mL of acetone to the solvent bottle 5 , Set the temperature of heating jacket 4 to 65 o C starts heating, turn on the switch of the ultrasonic probe 8, adjust the ultrasonic time 10 hours and ultrasonic frequency 20 KHz and other parameters. Wait for the temperature to reach 65 o After C, closely observe the dynamics of the steam in the solvent vapor condenser tube 8, and adjust the heating temperature to 68-70 appropriately o C, so that the vapor can smoothly rise to the top, and smoothly condense in the solvent vapor return pipe 7 and return to the sample bottle 1. After the gas-liquid circulation ...

[0050] Example 2

[0051] Taking a 100 g coal sample as an example, the extraction experiment was carried out by ultrasonic extraction.

[0052] Weigh 100 g coal sample into a 2000 mL large beaker, and add 600 mL of acetone to it, then place the large beaker in an ultrasound system for a total of 2 hours. After the ultrasound is completed, take out the large beaker and let it stand for 4 hours After the coal sample has settled, the coal sample and the extract are filtered and separated with a vacuum filtration device, and the obtained filtrate is distilled and concentrated with a rotary evaporator to remove the reagents to obtain the extract, and the obtained coal sample is placed back into the large beaker. One ultrasonic extraction is completed, and then the extraction is repeated according to the above steps until the extraction is complete. After the extract is basically colorless, the acetone extraction is completed. The ultrasonic extraction can be completed twice a day. The ...

[0053] Example 3

[0054] Taking a 1 g coal sample as an example, the Soxhlet extraction method was used for the extraction experiment.

[0055] Weigh 1 g coal sample, put it into the folded and weighed filter paper, roll the filter paper into a paper roll with the lower end sealed, carefully put it into the Soxhlet extractor, the size of the paper roll is just in the extraction tube Appropriate. Fix the round bottom flask with 200 mL of acetone on the heating mantle, and assemble the Soxhlet extractor with coal sample and the condenser, and wrap the interface with raw material tape to avoid poor contact and cause solvent waste. Pass the condensed water, turn on the heating jacket, adjust the heating power to keep the solvent from bumping, and after the extract is basically colorless, stop heating. After the extraction is completed, the acetone primary extraction time is 6 days in total, and 200 mL of acetone reagent is consumed.

Abstract

The invention relates to an ultrasonic continuous extraction device, which includes a sample bottle, a solvent bottle, heating sleeves, an ultrasonic extraction apparatus and condenser pipes. The sample bottle and the solvent bottle are respectively provided with a heating sleeve at the bottom. An ultrasonic probe of the ultrasonic extraction apparatus is sealed in the sample bottle. The two condenser pipes are horizontally communicated with the sample bottle and the solvent bottle inbetween. One of the condenser pipes is an extract liquid extraction pipe, is hermetically connected to the lower part of the sample bottle and the solvent bottle, and is downward inclined from the sample bottle to the solvent bottle, and the joint is provided with a filtration sand core connector. The other condenser pipe is a solvent vapor return pipe, is hermetically connected to the upper part of the sample bottle and the solvent bottle, and is downward inclined from the solvent bottle to the same bottle. The ultrasonic continuous extraction device provided by the invention can selectively and rapidly realize separation of group components in coal, and has the advantages of mild operation condition, simple operation, continuous extraction, high extraction efficiency, cycle use of solvent, no noise, no waste residue or wastewater discharge, and little exhaust emission.

Description

technical field [0001] The invention relates to a coal extraction device, in particular to an ultrasonic continuous extraction device. Background technique [0002] Solvent extraction of coal, especially under mild conditions, is a necessary and effective means to study the composition and structure of coal. The obtained extract can truly reflect the original chemical structure of coal, and some phenomena in the extraction process can reflect the nature of the interaction between coal molecules and the information of the interaction between coal and solvent. Not only that, solvent extraction can effectively realize the separation of organic components in coal from coal, and is expected to become a new method and an effective way to obtain chemicals from coal. [0003] Ultrasonic extraction and Soxhlet extraction are two commonly used methods in coal extraction research, but there are certain deficiencies in the process of use. Ultrasonic vibration is a physical auxiliary m...
