Rush tank, three-phase separator, Water Tank, slag ladle, oil tank；
The coal tar raw material tank passes sequentially through coal tar raw material pump, automatic backwashing filter, static mixer and institute
State the connection of separating feed surge tank, the separating feed surge tank be connected with the three-phase separator, the three-phase separator and
The Water Tank, slag ladle, oil tank connect respectively, and the Water Tank, slag ladle, oil tank are connected with sewage pump, pulp pump, oil pump respectively,
The demulsifier tank is connected with the static mixer by demulsifier pump.
The coal tar that the technical scheme provided by above-mentioned this utility model can be seen that the offer of this utility model embodiment is pre-
Process combined system, before separating treatment, add key demulsifier, in the presence of demulsifier, small particle hydrone it
Between realize combination, while combination each other is also achieved between small particle oil molecule, so as to thoroughly broken oil-in-water,
Emulsified water is thoroughly discharged from oil by water in oil general layout, at this moment again coal tar raw material is centrifuged and then may be used
Preferably to leave water and oil, the purpose being dehydrated to coal tar raw material is realized.

Coal tar pretreatment combination size system of the present utility model, its preferably specific embodiment is：
Including coal tar raw material tank, demulsifier tank, separating feed surge tank, three-phase separator, Water Tank, slag ladle, oil tank；
The coal tar raw material tank passes sequentially through coal tar raw material pump, automatic backwashing filter, static mixer and institute
State the connection of separating feed surge tank, the separating feed surge tank be connected with the three-phase separator, the three-phase separator and
The Water Tank, slag ladle, oil tank connect respectively, and the Water Tank, slag ladle, oil tank are connected with sewage pump, pulp pump, oil pump respectively,
The demulsifier tank is connected with the static mixer by demulsifier pump.
The method that above-mentioned coal tar raw material pretreatment combination size system of the present utility model realizes coal tar raw material pretreatment,
Comprise the following steps：
Coal tar in A, coal tar oil tank is heated to 70-90 DEG C by the heating coil in storage tank, keeps in storage tank
A period of time is stood, part moisture and coal tar are settlement separate, and the coal tar of bottom is pumped to step B by raw material to be carried out subsequently
Processing；
Solid impurity abjection in coal tar is arrived a diameter of through automatic backwashing filter by B, the coal tar of step A
20-100 μm, larger mechanical admixture in removing coal tar；
C, add demulsifier in the coal tar after step B process, demulsifier is with coal tar in pipe conveying procedure
In be sufficiently mixed；
D, the coal tar after being sufficiently mixed in step C is delivered in separating feed surge tank, make demulsifier quiet with coal tar
