Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a belt-driven partition board floating oil collector. Background Art

[0002] During the production of the isomerized dewaxing unit, oily wastewater with a water content of more than 99% is separated from the reflux tank at the top of the distillation tower according to the different physical properties of oil and water. The vacuum system of the reduced pressure distillation tower also produces oily wastewater. The oily wastewater collected by the daily device flows into the oily wastewater pool set up in the device. An oil layer of varying thickness floats on the surface of the wastewater. Since the liquid level is lower than the ground, equipment (floating oil collection plate) is required to merge the oil layer into it, and then the pumping equipment is started to suck the dirty oil containing a certain amount of water into the ground oil-water separator. The obtained water returns to the dirty oil pool, and the dirty oil is discharged into the dirty oil tank delivery device for refining.

[0003] The currently used floating oil collector sucks the floating oil to the ground under the negative pressure of the vacuum pump. During long-term use, due to the aging of pipelines and fittings, the working capacity of the vacuum pump decreases, the vacuum performance deteriorates, and the oil search effect is not good. In addition, the floating oil collection plate floats on the oil-water interface. Using the different densities of oil and water, the oil layer floating on the water surface flows into the center of the floating plate by gravity, and then is pumped to the ground by the equipment suction pipe. However, for thinner oil layers (such as less than 3mm), the surface tension of the floating plate is greater than the gravity, and it cannot rely on gravity to flow into the center of the floating plate, and cannot continuously and effectively separate the dirty oil layer.

[0004] Therefore, the use of floating oil collectors cannot separate thinner oil layers, and in the process of collecting floating oil, since the floating plate cannot float exactly on the oil-water interface, two situations will occur: part of the oil layer cannot flow into the floating plate, resulting in incomplete oil search, or a water layer of a certain thickness flows into the floating plate with the oil layer, and the amount of water carried by the floating plate increases. Subsequent treatment is required when refining the dirty oil, and there are certain hazards when catalysts are involved. Utility Model Content

The utility model does not use vacuum suction to avoid the problem of incomplete separation of the oil layer and water in the collection plate and incomplete oil search due to thin oil layer.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0024] See also Figure 1, this embodiment proposes a belt-driven partition oil floating collector including a belt conveyor, a plurality of de-oiling rollers 1 and a liquid storage tank 2; the belt conveyor includes a belt drive roller 3 and an annular belt 4; wherein the annular belt 4 is a belt of oleophilic and hydrophobic material, and in this embodiment, the material of the annular belt 4 is a belt of polypropylene fiber material; the annular belt 4 surrounds the periphery of the liquid storage tank 2, and rotatable belt drive rollers 3 are arranged at the four top corners of the annular belt 4, one of the belt drive rollers 3 is connected to a belt drive motor 5, and is used to drive the annular belt 4 to rotate around the liquid storage tank 2; an oil inlet 6 is arranged at the top of the liquid storage tank 2, and a plurality of de-oiling rollers 1 are connected to the oil inlet 6 of the liquid storage tank 2 through a support column 14; a plurality of de-oiling rollers 1 are distributed on the upper and lower sides of the corresponding annular belt 4, and the annular belt 4 runs between the de-oiling rollers 1 on the upper and lower sides, and the liquid adsorbed on the annular belt 4 is squeezed out by the de-oiling roller 1 up and down on the annular belt 4, and the squeezed liquid falls into the liquid storage tank 2 from the oil inlet 6.

[0025] The liquid storage tank 2 is divided into two interconnected parts, namely, a de-oiling storage tank 7 and an oil overflow storage tank 8. The de-oiling storage tank 7 is located below the oil inlet 6 so that the squeezed liquid can first enter the de-oiling storage tank 7. A partition with a circuitous structure is provided between the de-oiling storage tank 7 and the oil overflow storage tank 8. The partition with a circuitous structure includes a water barrier 12 and an oil barrier 13.

The top of the oil barrier 13 is connected to the top of the liquid storage tank 2, and the bottom of the oil barrier 13 is higher than the bottom of the liquid storage tank 2. As the liquid level in the de-oiling storage tank 7 rises, the oily components are located above the liquid level. The oily components first pass through the water barrier 12 and bypass the oil barrier 13 to enter the oil overflow storage tank 8, so as to further separate the oily components entering the de-oiling storage tank 7.

[0026] A water-cutting drainage guide 10 is provided at the bottom of one side of the de-oiling tank 7 of the liquid storage tank 2, and an oil-recovery drainage guide 11 is provided at the bottom of one side of the oil-overflowing tank 8 of the liquid storage tank 2.

After the adjustment is appropriate, the belt drive motor 5 is started to rotate the annular belt 4 to start absorbing the floating oil; when entering the deoiling roller 1, the dirty oil absorbed by the annular belt 4 is squeezed and flows into the deoiling tank 7. When the liquid level of the deoiling tank 7 rises, it overflows into the overflow oil tank 8 through the water separator 12 and the oil separator 13. The deoiling tank 7 and the overflow oil tank 8 are each provided with a shower for cutting water and draining oil recovery.

[0032] (4) Function of the water barrier 12: After the water brought by the adsorbed oil is collected and allowed to stand in the de-oiling tank 7, the water barrier 12 is used to prevent the water from entering the oil overflow tank 8, thereby obtaining dirty oil that is almost free of water.
