Referring to fig. 1, an oil-water separation system provided in an embodiment of the application includes: a melting furnace 10, a condenser 20 and a storage tank 30.

The melting furnace 10 is provided with a feed inlet 11, a feed outlet 12, an air outlet 13 and an oil seepage port 14. Wherein, the position of the air outlet 13 can be provided with an electric control valve, so as to control the opening and closing of the air outlet 13 through the electric control valve. The air outlet 13 is connected to the inlet end of the condenser 20. The outlet end of the condenser 20 is connected to a storage tank 30.

The melting furnace 10 is used for heating the internal materials to a first preset temperature so that water in the materials forms steam and then is discharged from the air outlet 13; the melting furnace 10 is also configured to heat the material therein to a second predetermined temperature to cause oil in the material to form oil and then to flow out of the oil seepage port 14.

After opening the feed inlet 11, selenium dioxide containing impurities can be charged into the melting furnace 10; the manner in which selenium dioxide is fed to the melting furnace 10 may be, for example, by means of a double screw conveyor; after feeding, the feed inlet 11 is closed, and the material can be heated by the melting furnace 10.

In this embodiment, the first preset temperature may be a temperature at which water evaporates, so that after the material is heated to the first preset temperature, the material, that is, the water solution inside the selenium dioxide evaporates to form water vapor, and then is discharged from the air outlet 13 to the condenser 20 to be condensed into water solution, and then enters the storage tank 30 for storage.

The second preset temperature may be a temperature at which oil impurities in selenium dioxide liquefy, so that after the material is heated to the second preset temperature, the oil impurities in the material may form oil, and then the oil seepage port 14 is opened to enable the oil to flow out of the melting furnace. And finally, a worker opens the blanking opening 12 to perform blanking on the selenium dioxide in the melting furnace 10. The manner of blanking may be, for example, a worker shoveling out by a shovel.

In the operation process of the oil-water separation system provided by the embodiment, a worker only needs to control the feeding and discharging of the melting furnace 10 and control the temperature of the melting furnace 10, so that continuous production for removing water and oil impurities in selenium dioxide containing impurities can be realized, and the selenium dioxide with higher purity is obtained, so that the effects of reducing the operation intensity of the worker, improving the treatment efficiency and improving the operation safety are realized.

It should be noted that, a ceramic fiber heating jacket may be disposed in the melting furnace 10, and the material may be heated by the ceramic fiber heating jacket. The air outlet 13 may be connected to the condenser 20 through a second connection pipe 32.

In one embodiment, referring to fig. 1 and 2, a second tank 40 is further included; the top of the tank 30 communicates with the second tank 40 through the connection pipe 31.

Specifically, after the gas enters the condenser 20, the water liquid condensed into liquid enters the storage tank 30, and then is discharged into the neutralization treatment tank through a drain pipe at the lower end of the storage tank 30, and after the neutralization treatment tank reaches the pH value, the water liquid can be recycled. Part of the evaporated gas in the water solution entering the storage tank 30 and the uncondensed gas passing through the condenser 20 enter the second storage tank 40, so that the excessive air pressure in the storage tank 30 is avoided to be unfavorable for liquid inlet.

The bottom of the second tank 40 may be connected to the neutralization tank through a drain pipe, and the top may be connected to the spray tower and the exhaust gas treatment system through an exhaust hole.

Further, a support stand 50 is also included; the tank 30 and the second tank 40 are provided on the support table 50; the support table 50 is provided with a step 51.

Through the support stand 50, the workday can be allowed to run to the support stand 50 to maintain and observe the valves on the storage tank 30 and the second storage tank 40; correspondingly, the storage tank 30 and the second storage tank 40 are respectively provided with a sight glass, so that staff can observe the liquid level inside. Meanwhile, the melting furnace 10 may be provided with a sight glass as well.

In one embodiment, referring to fig. 1, 3 and 4, the feed opening 12 is provided with an openable cover 15; the cover 15 is connected to the melting furnace 10 by bolts 16.

Specifically, after the cover 15 is removed, the discharge opening 12 is in an open state; correspondingly, after the sealing cover 15 is installed and the bolt 16 is screwed, the feed opening 12 is in a closed state.

In this embodiment, the oil seepage port 14 may be disposed between the bottom of the cover 15 and the melting furnace 10; when the bolt 16 is screwed to the sealing cover 15 to be in sealing connection with the melting furnace 10, the oil seepage port 14 is closed; when the bolt 16 is unscrewed to the extent that the sealing cover 15 is unsealed from the melting furnace 10, the oil seepage port 14 is opened.

Specifically, after the melting furnace 10 is heated to the second preset temperature, the oil in the melting furnace begins to precipitate, and at this time, the bolt 16 is unscrewed, so that a gap is formed between the sealing cover 15 and the melting furnace 10, and the gap is the oil seepage port 14, so that the oil can flow out from the gap.

Correspondingly, a drip pan for receiving oil may be placed under the cover 15.

Further, a packing seal 17 for sealing and connecting the cover 15 is provided on the outer periphery of the feed opening 12.

The packing sealing ring 17 may include a fluorine rubber packing sealing ring and a graphite packing sealing ring, so as to have a double sealing effect.

In one embodiment, the feed opening 11 is provided with a removable upper cover 18; the upper cover 18 is detachably connected to the melting furnace 10 by a hinge 191 and a hinge screw 192. When the upper cover 18 is opened, material may enter the melting furnace 10 through the feed port 11.

Among them, the hinge screw 192 and the hinge 191 may be provided in plurality and disposed around the outer circumference of the upper cover 18. The hinge 191 is rotatably connected with the melting furnace and is 匚 -shaped; after the hinge 191 is rotated to the buckle melting furnace 10, the hinge 191 can be locked and fixed by rotating the hinge screw 191.

It should be noted that the melting furnace 10 may be detachably assembled with the detachable top cover 120 and a bottomed furnace.

In another embodiment, referring to fig. 2, the condenser 20 is provided with: an air inlet 21, a liquid outlet 22, a cooling water inlet 23 and a cooling water outlet 24; the air inlet 21 is connected with the air outlet 13; the liquid outlet 22 is connected with the storage tank 30; the condenser 20 is provided with a cooling water flow passage; the cooling water inlet 23 and the cooling water outlet 24 are respectively arranged at two ends of the cooling water flow channel.

The cooling water inlet 23 may be disposed above the condenser 20 or below the condenser 20; the cooling water outlet 24 is the same.

As an embodiment, the air outlet 13 may be connected to the condenser 20 through the bellows 60, that is, the second connection pipe 32 may be connected to the condenser through the bellows 60, so that flexibility and fatigue resistance between the second connection pipe 32 and the condenser 20 may be improved, thereby improving safety and reliability of the system.
