For achieving the above object, technical scheme of the present invention is as follows:
A kind of ultrasonic wave is assisted-the liquid-liquid spray extraction device, include the container b of the container a of a splendid attire organic solvent, a splendid attire sample, an extractor, a ultrasonic sound appratus that is arranged on below the extractor, container a is connected feed pipe with container b, the other end of feed pipe connects shower nozzle and is communicated in extractor, feed pipe is provided with pump, the extractor lower end is provided with drainage conduit, the return duct that its upper end is provided with outlet pipe and communicates with feed pipe, return duct is connected with the extension type conduit of setting in the extractor.
Described ultrasonic sound appratus is close to the bottom of extractor.
Described extractor is to be connected in sequence from top to bottom by three round-bottomed flasks.
Described container a and container b be connecting duct a and conduit b respectively, and the other end of the other end of conduit a and conduit b is connected in an end of feed pipe jointly, is respectively arranged with flowmeter and valve on conduit a and the conduit b.
On the described drainage conduit valve is installed.
On the described return duct triple valve is installed.
Described shower nozzle is connected with removably with feed pipe, extractor.
Operation principle of the present utility model: utilize pump to feed extractant in the extractor earlier, sample enters in the extractor with atomizing type by a shower nozzle and contacts with extractant then, because the atomizing of shower nozzle makes sample contact with extractant with the form of droplet, improved extraction efficiency, by pump control fogging degree.Simultaneously below extractor, be close to a ultrasonic sound appratus, make under the effect of ultrasonic sound appratus when sample enters extractor that sample contacts with extractant with littler drop form, further improved extraction efficiency.Stripped sample can carry out cycling extraction by the return duct of extractor upper end.Cycle-index can require to control according to measuring.
The utility model will have liquid-liquid extraction (LLE) technology now and improve, design has also been made ultrasonic wave and has been assisted-liquid-liquid spray extraction (USA/LLSE) new equipment, device after utilize improving carries out enrichment can overcome a lot of shortcomings in existing liquid-liquid extraction (LLE) technology fully, the utility model has saved traditional manpower or machinery rocks step, sample is sprayed with vaporific form from a shower nozzle, contact with organic solvent, the contact surface that has increased sample and organic solvent is long-pending, improved extraction efficiency, simultaneously under the effect of ultrasonic sound appratus, further increased the probability of object and organic solvent effect, improved extraction efficiency, the sample that was extracted can also carry out cycling extraction.New type ultrasonic is auxiliary-and liquid-liquid spray extraction (USA/LLSE) Design of device not only reached the extraction of big low capacity water sample, had advantages such as solvent load is few, extraction efficiency is high, automation simultaneously.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is to the schematic diagram of the dimethylbenzene rate of recovery in the organic facies in the experiment;
The specific embodiment
With reference to figure 1, a kind of ultrasonic wave is assisted-the liquid-liquid spray extraction device, include the container a6 of a splendid attire organic solvent, the container b8 of a splendid attire sample, an extractor 12 that is connected in sequence from top to bottom by three round-bottomed flasks, one be arranged on below the extractor 12 and with its ultrasonic sound appratus that is close together mutually 14, the conduit a1 that connects container a6 is connected in feed pipe 17 1 ends jointly with the conduit b7 that is connected container b8, conduit a1 is provided with flowmeter a2 and valve a3, conduit b7 is provided with flowmeter b15 and valve b16, the other end of feed pipe 17 connects shower nozzle 13 and is communicated in extractor 12, shower nozzle 13 places in the round-bottomed flask bottom of extractor 12, described shower nozzle and feed pipe, extractor connects with removably, be provided with pump 18 on the feed pipe 17 successively, current meter 19, water pressure gauge 20, valve c21, extractor 12 round-bottomed flask bottom bottom is provided with drainage conduit 22, valve d23 is installed on the drainage conduit 22, the return duct 5 that the upper end of extractor 12 round-bottomed flask topmost is provided with outlet pipe 9 and communicates with feed pipe 17, triple valve 4 is installed on the return duct 5, its two-port is connected on the feed pipe 17 of pump 18 both sides, the 3rd port of the return duct that is connected with triple valve 4 is connected with the extension type conduit 11 of setting in the extractor 12, valve e10 is installed, conduit a1 on the outlet pipe 9, conduit b7, feed pipe 17, drainage conduit 22, outlet pipe 9, return duct 5, extension type conduit 11 is made by polytetrafluoroethylmaterial material.
Before the experiment beginning, will add organic solvent among the container a earlier, in container b, add water sample.When beginning experiment opens valve a and pump simultaneously, and organic solvent enters in the extractor by feed conduit, pump and valve a closed simultaneously after a certain amount of when organic solvent enters; Then pump and valve b are opened simultaneously, this moment, ultrasonic sound appratus was also opened, water sample can enter in the extractor by feed pipe with certain flow velocity, shower nozzle must be under the organic solvent liquid level, because the density of water and organic solvent is different, so can be separated rapidly after entering water sample and the organic solvent contact in the extractor, extractor be by three independently round-bottomed flask be formed by connecting, the volume of round-bottomed flask can be determined according to the amount of measuring water sample.After water sample all sprayed into extractor, b closed with valve, adjusted triple valve, and water sample carries out cycling extraction under the effect of pump.Cycle-index can be controlled according to the requirement to sample determination.This device can be handled big low capacity water sample by full automation, also can reach big capacity continuously from the extraction purpose.
