[0030] Embodiment 2:

[0031] See also Figure 1-Figure 6 , a tertiary amine oil-water continuous separation device, further comprising an auxiliary mechanism 4 disposed above the separation mechanism 2 3, the auxiliary mechanism 4 comprising a connecting groove opened at the opening above the separation tank 2 301, a rotating rod 401 passing through the inner wall of the connecting groove, a shielding cover 402 disposed on the surface of the rotating rod 401, a sealing gasket 403 is installed at a position relative to the opening of the separation tank 2 301, the sealing gasket 403 is in contact with the opening of the separation tank 2 301, and a plurality of lock buckles 404 are fixedly installed on the shielding cover 402 and the outside of the separation tank 2 301;

[0032] A collecting mechanism 5 is installed below the separation tank 1 and the separation mechanism 2 3. The collecting mechanism 5 includes a collecting box 501 through which a drain pipe 304 and one end of an output pump 305 penetrate.

[0034] In summary, with the aid of the above-mentioned technical scheme of the utility model, during operation, the tertiary amine oil and water cooperate with each other through the input pipe 201 and the delivery pump 202, so as to facilitate the delivery of the tertiary amine oil and water to the separation tank 1. At the same time, the hollow motor 203 provided in the separation tank 1 drives the hollow rod 204 and the separation blade 205 to cooperate with each other, so that the tertiary amine oil and water being delivered rotates at a high speed in the separation tank 1 to generate a centrifugal force field. Then, under the action of the centrifugal force, the water with high density is thrown to the inner wall of the separation tank 1, and flows downward along the inner wall of the separation tank 1 to the drain pipe 304. Then, the separated water is transported to the collection box 501 and filtered through the activated carbon plate 503. After filtering, it passes through the drain pipe 505 and cooperates with the control valve 506 to facilitate the discharge of the separated water. At the same time, the water with high density is separated. The oil is brought into the output pipe 206 through the hollow rod 204 and overflowed to the coalescing filter element 303 set in the separation tank 2 301, so as to facilitate the coalescence of extremely small water droplets into larger water droplets. Most of the coalesced water droplets can be separated from the oil by their own weight and settled in the separation tank 2 301 for separation. Then the separated oil flows through the separation filter element 307. Since the separation filter element 307 has good oleophilic and hydrophobic properties, the water is further separated. Finally, the clean and water-free oil passes through the oil drain pipe 6 and the control valve 2 7, so as to facilitate the discharge of the separated oil. The residual water in the separated oil passes through the drain pipe 304 and the output pump 305 to cooperate with each other, so as to facilitate the transportation to the collection box 501 and pass through the activated carbon plate 503 for filtration. After filtration, it passes through the drain pipe 505 and the control valve 1 506 to cooperate with each other.
