[0003] Industrial wastewater is generally a mixture of oil, water, mud and other impurities. If it is discharged directly into rivers, it is easy to cause environmental pollution. However, the wastewater is purified by large-scale industrial wastewater treatment equipment. The overall purification process is time-consuming, multi-step and complex, which affects the purification efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an oil-water-sand three-phase separation device to solve the above-mentioned problems existing in the prior art.

[0005] Technical solution: An oil-water-sand three-phase separation device includes a cylinder, a feed port is provided on one side of the cylinder, and a discharge port is provided on the other side. One side of the feed port is fixedly connected to an inlet cyclone, and the inlet cyclone is provided inside the cylinder;

[0006] The inlet cyclone includes a cyclone body, a separation pipe connected to the cyclone body, a container pipe is provided between the separation pipe and the cyclone body, the bottom of the separation pipe is connected to the cylinder, and the separation pipe and the cyclone body are supported by an I-steel plate.

[0007] In a further embodiment, a triangular rib is provided on a side of the cyclone body close to the container connecting pipe.

[0008] In a further embodiment, the container connecting pipe and the cyclone body are fixedly connected via a fixing rib.

[0009] In a further embodiment, the cylinder is fixedly connected to the inner walls on both sides of the cyclone body via straight ribs.

[0010] In a further embodiment, a demister is further provided inside the cylinder, and the demister is configured as a multi-plate parallel demister.

[0011] In a further embodiment, a fixed support and a sliding support are respectively provided at both ends of the bottom of the cylinder.

[0012] In a further embodiment, a gasket is provided between the feed port and the inlet cyclone. Beneficial effects

[0013] Sewage enters the inlet cyclone through the feed port, first enters the inlet diversion position, and impacts the cyclone body, causing a significant change in the direction and speed of the separated liquid. This sudden change in liquid flow momentum causes the pre-separation of oil, water and sand. The pre-separated liquid falls into the cyclone, providing sufficient time for the oil sand to gather in the upper layer and the water to settle to the bottom. In most designs, a container is installed to introduce the pre-separated liquid below the oil-water interface, which can promote the coagulation of water droplets. The pre-separated oil sand enters the cylinder and is discharged through the demister after sedimentation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention.

[0021] It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

[0022] In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0023] like Figure 1-Figure 5 As shown, an oil-water-sand three-phase separation device consists of a feed inlet 1, a gasket 2, an inlet cyclone 3, a cylinder 4, a demister 5, a sliding support 6, a fixed support 7, a cylinder 8, a straight rib 9, an I-steel plate 10, a container pipe 11, a triangular rib 12, a cyclone body 13, a fixed rib 14, and a separation tube 15.

[0024] A feed port 1 is provided on one side of the cylinder 4, and a discharge port is provided on the other side. One side of the feed port 1 is fixedly connected to an inlet cyclone 3, which is provided inside the cylinder 4.

[0025] The inlet cyclone 3 includes a cyclone body 13, a separation pipe 15 connected to the cyclone body 13, a container pipe 11 is arranged between the separation pipe 15 and the cyclone body 13, the bottom of the separation pipe 15 is connected to the cylinder 8, and the separation pipe 15 and the cyclone body 13 are supported by an I-steel plate 10.

[0026] A triangular rib 12 is provided on one side of the cyclone body 13 close to the container connecting pipe 11 .

[0027] The container connecting pipe 11 and the cyclone body 13 are fixedly connected via a fixing rib 14 .

[0032] How it works

[0033] Sewage enters the inlet cyclone 3 through the feed port 1, first entering the inlet diversion position and impacting the cyclone body 13, causing the direction and velocity of the separated liquid to change significantly. This sudden change in liquid flow momentum causes the pre-separation of oil, water and sand. The pre-separated liquid falls into the cyclone, providing sufficient time for the oil sand to accumulate in the upper layer and the water to settle to the bottom. In most designs, a container pipe 11 is provided to introduce the pre-separated liquid below the oil-water interface, which can promote the coagulation of water droplets. The pre-separated oil sand enters the cylinder 8 and is discharged through the demister 5 after sedimentation.
