An oil outlet 106 is arranged at the bottom of the oil storage tank, a bottom liquid outlet valve 1056 is arranged at a position close to the oil outlet 106, and the bottom liquid outlet valve 1056 is used for opening and closing the oil outlet 106 so as to control outflow of heavy oil. The bottom outlet valve 1056 is located below the location of the return 1052.

By adopting the volatile oil collecting device 100 in the scheme, when the bottom liquid outlet valve 1056 and the lower liquid outlet valve 1055 are closed, the mixed liquid starts to automatically separate oil and circularly flow, and the extracting liquid sequentially flows through the liquid outlet device 107, the second branch 1058, the overflow port 1053, the first branch 1057, the reflux port 1052 and the liquid inlet device 104 and flows back into the liquid storage cavity 1011, so that the extracting liquid in the oil storage tank 101 can be automatically recovered, and the extracting liquid is not required to be recovered by a manual switch valve.

Illustratively, a middle liquid outlet valve 1054 is disposed in the outflow direction of the second outer distribution pipe 1072, and when the bottom liquid outlet valve 1056 is opened and the middle liquid outlet valve 1054 and the lower liquid outlet valve 1055 are closed, the heavy oil at the bottom of the liquid storage cavity 1011 flows out through the oil outlet 106, so as to collect the heavy oil. When the collection of the heavy oil is finished, the bottom liquid outlet valve 1056 is closed, the lower liquid outlet valve 1055 and the middle liquid outlet valve 1054 are opened, and the light oil on the top layer can flow out or be collected through the backflow port 1052.

Illustratively, the circulation line 105 further includes a third branch 1059, the third branch 1059 being in communication between the lower outlet valve 1055 and the bottom outlet valve 1056. So that the lower liquid outlet valve 1055 and the bottom liquid outlet valve 1056 are both under the same atmospheric pressure with the liquid storage cavity 1011, and the whole circulation pipeline 105 is communicated with the atmosphere of the liquid storage cavity 1011, thereby being convenient for applying the communicating vessel principle.

Specifically, the bottom liquid outlet valve 1056 includes a first bottom liquid outlet valve 10561 and a second bottom liquid outlet valve 10562, which are respectively disposed on the third branch 1059 and are respectively disposed on two sides of the position where the oil outlet 106 is located, and an oil receiving port is disposed along the flowing direction of the heavy oil in the flowing direction of the first bottom liquid outlet valve 10561; the second bottom outlet valve 10562 is disposed away from the oil drain. When the above-described process for collecting heavy oil is performed, the first bottom outlet valve 10561 is opened, and the heavy oil is collected via the oil collecting port.

Illustratively, the oil storage tank 101 is a straight-tube structure, and the aspect ratio of the oil storage tank 101 may be (3-8): 1.

illustratively, the length to diameter ratio of the storage tank 101 is 5:1. the device is used for loading and volatilizing the mixed liquid, and the structural form of the device is favorable for separating light and heavy oil.

Illustratively, the spacing between two adjacent first apertures is between two and five times the aperture size of the first apertures. The distance between two adjacent second small holes is between two and five times of the aperture size of the second small holes. The sum of the cross-sectional areas of the first apertures 10413 is between three and eight times the cross-sectional area of the inlet 102. For example, when the apertures of the first and second apertures 10413, 10413 may be provided with 92, and the sum of the cross-sectional areas of the 92 first apertures 10413 may be 5 times the cross-sectional area of the 25mm inlet 102. So as to effectively ensure the liquid inlet efficiency and simultaneously reduce the impact of the liquid inlet on the liquid level of the mixed liquid. And because the single cross-sectional area of the second small hole is far smaller than the cross-sectional area of the liquid outlet, the liquid outlet is slower, and the layering between the heavy oil and the extracting solution is not disturbed, so that the outflow of the heavy oil is further limited.

In combination, the extracted volatile oil mixed solution passes through a liquid inlet device 104 and a porous distribution pipe (the liquid inlet device 104 and a liquid outlet device 107), and the flow rate of the volatile oil mixed solution is limited, so that the volatile oil mixed solution is fully separated in a volatile oil straight barrel with the length-diameter ratio of 5:1, and light oil, extracting solution and heavy oil are sequentially separated from top to bottom. In this process, light oil is at the upper layer, the extract is at the middle layer, and heavy oil is at the bottom layer. The liquid outlet device 107 is opened, the first bottom liquid outlet valve 10561 and the second bottom liquid outlet valve 10562 are closed, the lower liquid outlet valve 1055 is closed, and the volatile oil mixed liquid starts to automatically separate oil circulation. The extracting solution in the collecting device passes through the liquid outlet device 107 and the overflow port 1053 in the circulating pipeline 105 to the reflux port 1052 in the circulating pipeline 105, the effect of automatically recycling the extracting solution is realized in the production process through the arrangement of the circulating pipeline 105, a manual switch valve is not needed for recycling the extracting solution, meanwhile, the extracting solution passes through the liquid outlet device 107 and the multi-pore distribution pipe of the liquid outlet device 107, the liquid outlet speed of the extracting solution is limited, namely, the extracting solution passes through the overflow port 1053 to the reflux port 1052, the mixed solution is not disturbed in layering in the volatile oil straight barrel, the overflow port 1053 and the liquid inlet device 104 are arranged at the same height, so that the volatile oil mixed solution continuously enters, the extracting solution can be guaranteed to flow back from the overflow port 1053, the overflow of the volatile oil straight barrel is not influenced, and the layering of the mixed solution is not influenced, thereby realizing the functions of automatically collecting and separating oil and water.
