The specific application method and operating procedure of the present invention：
Step 1）The fill process of extraction kettle
Step 1.1）：Extractant is added, is first turned on the tail gas valve of extraction kettle, then opens the extractant of extractant tank and goes out
Mouth main valve and the extractant from valve and extraction kettle enter main valve and from valve, and extractant is made to be passed through by extractant tank
Extractant supply line enters in extraction kettle, when extractant inlet reaches 1/3 height of extraction kettle volume, closes extraction successively
Kettle extractant is taken to enter valve and extractant tank extractant outlet valve；
Step 1.2）：It adds materials, under conditions of the tail gas valve of extraction kettle is opened, opens material pot successively in order
Material outlet main valve, the material inlet valve from valve and extraction kettle, material is made to enter in extraction kettle, when tar waste and
When the total volume of extractant reaches 2/3 height of extraction kettle volume, the material inlet valve of extraction kettle, material pot are successively closed
Material outlet is from the tail gas valve of valve, main valve and extraction kettle；
Step 2）The extracting operation process of extraction kettle, while the blender and heating unit of extraction kettle are opened, heating extraction
Mixing liquid in kettle keeps the temperature 1h to 45 ± 2 DEG C, stops heating afterwards, closes blender, stands 0.5h；
Step 3）Solution extraction process and the decentralization process of residue are extracted in extraction kettle
Step 3.1）：Extract liquor is extracted, is first turned on the tail gas valve of extraction kettle and surge tank, opens extraction successively in order
The extract liquor liquid valve door of kettle and the extract liquor liquid flowing valve of surge tank are taken, by the power of vacuum pump, the extraction in extraction kettle
Solution is taken all to be pumped into surge tanks, then close successively the tail gas valve of extraction kettle, surge tank extract liquor liquid flowing valve and
The extract liquor liquid valve door of extraction kettle；
Step 3.2）：Be heating and curing tar residue, the hot vapour dump valve being first turned between extraction kettle and No. two condensers
Door opens the heating unit and blender of extraction kettle, drives in extraction kettle that minimal amount of solvent and lightweight have in thermal softening pitch out of
Machine object, residue are heated to 150 DEG C, residue are enable to trickle, and close hot vapour discharge valve, heating unit and blender afterwards；
Step 3.3）：Decentralization cures tar residue, opens and cures the tail gas valve of tar tank, cures tar outlet valve
Door, slowly unlatching compressed air supply valve, forces the thermal softening pitch after extraction to flow into curing by curing tar discharge pipe
In tar tank, according to the amount of storage for curing tar tank, close and cure tar outlet valve to replace curing tar tank, until residual
Until being discharged under slag；
Step 4）：The process of extractant recycling and the decentralization process of tar light oil
Step 4.1）：Surge tank and the tail gas valve of distillation still are first turned on, then is opened between surge tank and distillation still
Extract liquor discharges main valve, from valve, and by the power of high potential difference, extract liquor enters distillation still by surge tank, when extract liquor
When liquid level reaches the 2/3 of distillation still depth, surge tank and the tail gas valve of distillation still are closed；

The switch of outlet valve, the tail gas valve of extractant tank and No.1 condenser；The blender and heating unit of distillation still are opened,
Extract liquor is heated to 75 ± 5 DEG C, hot steam enters No.1 condenser by steam output pipe and is condensed into extractant, then passes through extraction
Agent extraction tube is instilled in extractant tank, is realized the continuous still concentration of extraction solution and the continuous recycling separation of extractant, is worked as base
Originally there is no condensate liquid to be flowed out from No.1 condenser, close the heating unit and blender of distillation still, steam off outlet valve,
The switch of extractant outlet valve and No.1 condenser；
Step 4.3）：Under conditions of the closing of steam (vapor) outlet valve, the tail gas valve of distillation still and tar light oil tank is opened,
The tar light oil outlet valve of distillation still is opened, releases the tar light oil after extraction in distillation still, it is burnt according to lightweight
The amount of storage of oil tank closes tar light oil outlet valve and replaces tar light oil tank, until discharge under tar light oil residue for
Only, the tail gas valve of tar light oil outlet valve, distillation still and tar light oil tank is closed afterwards.
Further, it is rapid in step 1.1）During extractant feed, if extractant supply line goes wrong, it will use
Extractant spare duct, specific method are：The extractant on extractant supply line is exported to be closed from valve, according to
Secondary opening extractant outlet main valve, extractant outlet on extractant spare duct is from valve and the extractant entrance of material pot
Valve makes extractant enter material pot by extractant spare duct and is mixed with material, and mixture is added by material supply line
It is added in extraction kettle, material and extractant is supplied simultaneously for extraction kettle.
The beneficial effects of the invention are as follows：As a result of said program, selected suitable extraction is utilized in complete set of equipments
Agent is taken, it can quick under the conditions of as mild as a dove, easy realizationization production tar waste solid-liquid ingredient separation；Utilize the complete set of equipments
The recycling repeatedly that can complete extraction agent uses；Extractant used is the relatively low solvent of boiling point, operated into middle and saves operation
Energy and cost；Since unit operation is carried out in the equipment of closing, condenser used by complete set of equipments of the invention
Condensation effect is notable, and environmental pollution is small and is easily recycled and recycles；The present invention complete set of equipments be expected to large-scale production and
It utilizes, the being easily solved production intractable problem of tar waste.
Advantage：It being capable of quick under the conditions of relatively mild, easily realizationization production tar separation of solid and liquid.Complete equipment extracts
Agent is taken to repeat to recycle, tail gas focuses on, and environmental pollution is small；It is easily industrialized and separative efficiency is high.
