Description
Technical field
The present invention is with carbon tetrachloride or other extractants, and the oily substance in extraction water, before measuring total extract
Processing means, can be used for the mineral oil in surface water, subsoil water, sanitary sewage, industrial wastewater and vegetable and animals oils and the catering trade
Oil smoke discharge detects, it is adaptable to the enterprises and institutions such as environmental monitoring station, hydrometric station, petrochemical industry, machinery, carplane manufacture,
The industries such as medicine, agricultural science and technology, sea transport.
Background technology
In existing extraction water, the method for oily substance has separatory funnel hand-rail type extraction and automatic jet extracting process
Deng.
Separatory funnel hand-rail type extracts, and is the traditional mode of comparison that uses of current laboratory, it is simply that use separatory funnel
With the mode of artificial vibration, this method and heaviness thereof, extraction efficiency is low, and hand labor intensity is big, and used when extracting
Organic solvent such as carbon tetrachloride also can bring infliction of body to experimenter.
Automatically the operation principle of jet extracting process is water sample and the carbon tetrachloride of certain volume to be poured into by jet bottleneck
In sample storage bottle, open vacuum pump and carbon tetrachloride and water sample are all drawn onto in jet bottle by jet bottle afterbody pore.Due to four
Chlorination carbon ratio water weight, is deposited on bottom, and carbon tetrachloride is drawn onto the bottom of jet bottle, penetrates when water sample is drawn onto by pore pipe from sample storage bottle
During stream bottle, water sample passes through carbon tetrachloride, obtains partial extraction.Then, vacuum pump, carbon tetrachloride and water sample are closed by thin
Hole jet fierceness hits outlet at bottom valve glass wall, makes the contact impact of carbon tetrachloride and water sample, has reached the purpose of extraction.The party
Formula is only applicable to sample volume extraction within 500mL, and when sample volume is more than 500mL, vacuum pump is drawn time-consuming, causes
Whole hybrid extraction process time lengthens, and strengthens, jet bottle, liquid containing bottle volume requirement as wanted to realize the extraction of multiple sample
Taking, whole device seems heavy, and does not has automatic cleaning function.It addition, this instrument all only has auto extractive merit in the market
Can, sample-adding needs artificial quantitative sample injection, dosing process, also can bring infliction of body to experimenter.
Summary of the invention
For the human injury overcoming defect and the organic solvent volatilization etc. of above-mentioned existing common technology to bring, this device uses
Using airflow disturbance abstraction technique, extraction time is short, and extraction yield is more than 95%, and device devises quantitative feed liquor function, can be real
Enter extractant 50mL the most every time；Device have also been devised 8 sample introduction cups: each sample introduction cup accommodates water sample 1000mL to be measured, can be real
The most automatically sample, extract, discharge opeing, cleaning, save manpower, save the time, decrease operator simultaneously and contact harmful examination
The chance of agent, safer.
For achieving the above object, the present invention provides the pretreating device of oily substance in a kind of extraction water, described pre-treatment
Device includes sample introduction cup, extraction flask, carbon tetrachloride liquid containing bottle and air pump, and described sample introduction cup and carbon tetrachloride liquid containing bottle are with described
The upper flow connection of extraction flask, described extraction flask is provided with liquid outlet, and described air pump is in fluid communication with described liquid outlet.
Preferably, described sample introduction cup is 8.
Preferably, described pretreating device also includes magnesium carbonate post and the membrane separator being in fluid communication with described liquid outlet,
The outlet at bottom of described magnesium carbonate post is in fluid communication with described membrane separator.
Preferably, described pretreating device also includes that waste liquid barrel, described waste liquid barrel are in fluid communication with described liquid outlet.
Present invention have the advantage that
1) using airflow disturbance abstraction technique, extraction yield is more than 95%.
2) automaticity is high: integrates sampling, extraction, discharge opeing automatically, clean, can 8 samples of sequential processing, it is not necessary to
Artificial replacing, it is achieved unmanned, saves manpower and time.
