Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Appended drawing reference: it is de- that 1- pre-processes tank, 2- filter, 3- standing kettle, 4- heavy oil storage tank, 5- light oil storage tank, 6- heavy oil
Water kettle, 7- condensing unit, 8- light oil dehydrating kettle, 9- incinerator, 10- heating device.
Specific embodiment
Further specific detailed description is done to the utility model with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of coal tar layering recovery system includes:
Tank 1 is pre-processed, so that coal tar well cuts is settled for demulsifier and flocculant to be added；
Filter 2 separates solid impurity for being filtered to the coal tar from pretreatment tank 1；
Kettle 3 is stood, for light oil release agent is added in the coal tar from filter 2, standing to make coal tar be divided into two
Layer, upper layer is that light oil lower layer is heavy oil；
Heavy oil storage tank 4, for storing from the heavy oil for standing 3 lower layer of kettle, diesel oil, heavy oil can be made in heavy-oil hydrogenation
The also available recycling of the high added values such as middle naphthalene, anthracene, phenanthrene and pyrene fine chemicals；
