Description
Technical Field
The utility model relates to a special four-phase separator for oily sludge treatment.
Background
The oily sludge is mainly derived from oil separation tank bottom mud, floating slag in a flotation tank, crude oil tank bottom mud and the like of petrochemical production enterprises and is commonly called as oil sludge. The oil-containing sludge has different compositions, generally has the oil content of 10-50 percent and the water content of 40-90 percent, and is accompanied by a certain amount of solids. The oily sludge contains a large amount of pathogenic bacteria, parasitic ova, heavy metals such as copper, zinc, chromium and mercury, salts, polychlorinated biphenyl, dioxin, radioactive nuclide and other refractory toxic and harmful substances, and if the oily sludge is not treated and directly discharged, the oily sludge not only occupies a large amount of cultivated land, but also pollutes surrounding soil, water and air.
According to national statistics yearbook data, the quantity of the domestic existing oily sludge reaches the level of 500 ten thousand tons per year, and the method becomes a great problem for restricting the sustainable development of the petrochemical industry. Meanwhile, the new national standard soil environmental quality agricultural land soil pollution risk management and control standard (trial) is implemented from 8.1.2018, so that the treatment of the oil sludge by "transformation into three" is imperative.

Fig. 2 is a second schematic structural diagram of an embodiment of the present invention.
Fig. 3 is a third schematic structural diagram of the embodiment of the present invention.
Detailed Description
In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1 to 3, a four-phase separator for treating oily sludge comprises a shell 1, a scum collecting barrel 2, a distributor 3, a scum collector 4, a feed inlet 5 communicated with the distributor, the distributor communicated with the scum collecting barrel, the bottom end of the scum collecting barrel communicated with the shell and the top end communicated with the scum collector, the upper periphery of the scum collector communicated with a scum discharge port 6 and the lower periphery communicated with an oil discharge port, the bottom end of the shell communicated with a scum discharge port 7 and the top end communicated with a water discharge port 8.
The embodiment of the utility model provides an in, the dross collecting vessel is located inside the shell, and the distributing device is located inside the dross collecting vessel.
The embodiment of the utility model provides an in, the upper and lower both ends of distributing device and dross collecting vessel are uncovered, the uncovered inside dross collector upper end of intercommunication shell in upper end of dross collecting vessel.
The embodiment of the utility model provides an in, the distributing device includes cloth cartridge 9, links firmly pointed end conical cap 10 up on cloth cartridge's the lower extreme is uncovered, has first through-flow clearance 11 between conical cap upper portion and cloth cartridge's the lower extreme is uncovered, has second through-flow clearance 12 between conical cap week portion and the dross collecting vessel.
In the embodiment of the utility model, the lower extreme of dross collecting vessel is uncovered to be close to the row's cinder notch of the bottom in the shell.
In the embodiment of the present invention, the oil discharge port is composed of the first oil discharge port 13 and the second oil discharge port 14.
In the embodiment of the present invention, the inner top of the housing is provided with an overflow ring groove 15, and the water outlet is communicated with the overflow ring groove.
The working principle of the special four-phase separator for treating the oily sludge is as follows: the oil-containing sludge treated by adding the dispersing agent enters the distributing device through the feeding hole, and the flow rate and the impact action of the material are slowed down through the blocking of the distributing barrel and the conical cap. The materials begin to realize the four-phase separation of oil, water, sediment and scum, the sediment has higher specific gravity, moves towards the bottom of the shell, is deposited to a certain degree and is discharged through a slag discharge port. The specific gravity of the separated oil and the scum is lighter, the separated oil and the scum move upwards under the collecting action of the scum collecting barrel and flow into the scum collector through the upper opening of the scum collecting barrel, and the scum is discharged from the scum discharge port on the upper part of the separated oil in the scum collector and the separated oil is discharged from the first oil discharge port and the second oil discharge port because the specific gravity of the scum is lighter than that of the separated oil. The separated water slowly flows upwards from the gap between the shell and the scum collecting cylinder, slowly flows in an overflow mode under the action of the overflow ring groove and is discharged through the water outlet. The utility model discloses equipment can realize the four-phase separation of oily sludge, and area is little, and separation efficiency is high, can realize 24 hours continuity of production, is the environmental protection trade, especially petroleum refining oily sludge handles indispensable four-phase splitter.
The utility model is not limited to the above best mode, and any person can obtain the special four-phase separator for oil-containing sludge treatment in other various forms under the teaching of the utility model. All the equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
