[0022] The following reference Figure 1 and Figure 2 The evaporator separator described in the embodiments of this application is explained.

[0023] See Figure 1 and Figure 2 As shown, an embodiment of this application provides an evaporator separator, which includes: a separator body 8, an overflow weir, a liquid outlet pipe 3, and a flow turbulence device. The separator body 8 is specifically the body of a common evaporator separator in the prior art. The interior of the separator body 8 is hollow, forming a cavity. Evaporated liquid mixed with oil is filled into the separator body 8. An overflow weir is disposed within the separator body 8, and an overflow port 9 is provided on the side wall of the separator body 8. The overflow weir communicates with the overflow port 9, and the liquid level of the evaporated liquid at the overflow weir is higher than the height of the overflow port 9. The liquid outlet pipe 3 specifically... The separator is a ring-shaped pipe. The liquid outlet pipe 3 is arranged around the outside of the separator body 8 and is connected to the overflow port 9. This allows some of the evaporating liquid and the oil floating on the surface of the evaporating liquid to flow through the overflow weir to the overflow port 9 and into the liquid outlet pipe 3. This allows most of the oil floating on the surface of the evaporating liquid in the cavity to flow to the liquid outlet pipe 3, preventing the oil from accumulating at the surface of the evaporating liquid. The turbulence device is partially set inside the separator body 8. The turbulence device can agitate and scrape the evaporating liquid at the surface of the evaporating liquid, promote the overflow of oil, and improve the oil separation effect.

[0024] Specifically, the separator body 8 is cylindrical, and there are multiple overflow ports 9. Optionally, there are four overflow ports 9, which are equally spaced along the circumference of the separator body 8. Of course, the number of overflow ports 9 is not limited to four.

[0025] Furthermore, the liquid outlet pipe 3 is arranged around the four overflow ports 9, and a connecting pipe is provided at the position of the liquid outlet pipe 3 directly opposite the overflow ports 9, so that the overflow ports 9 are connected through the connecting pipe.

[0026] Preferably, the outlet pipe 3 is provided with a flushing port, which can be connected to an external pipeline for introducing pure water or purging gas to periodically flush the outlet pipe 3 and prevent the outlet pipe 3 from becoming blocked.

[0027] Furthermore, the overflow weir includes a connecting ring 5 and a liquid level limiting ring 2 disposed on the connecting ring 5. Preferably, the connecting ring 5 and the liquid level limiting ring 2 have an integral structure. Optionally, the connecting ring 5, the liquid level limiting ring 2, and the cavity are coaxially arranged. The outer ring edge of the connecting ring 5 is connected to the inner wall surface of the separator body 8, and the height of the connecting ring 5 is not higher than the height of the lower edge of the overflow port 9.

[0028] The liquid level limiting ring 2 is connected to the inner ring edge of the connecting ring 5 at its bottom edge, so that the liquid level limiting ring 2 and the connecting ring 5 are set perpendicularly. The upper edge of the liquid level limiting ring 2 is higher than the upper edge of the overflow port 9. The liquid level of the evaporating liquid in the cavity is located inside the liquid level limiting ring 2, and the liquid level of the evaporating liquid is not lower than the bottom edge of the liquid level limiting ring 2. Preferably, the liquid level of the evaporating liquid is level with the upper edge of the liquid level limiting ring 2.

[0029] Furthermore, this evaporator separator also includes a reflux pipe 4. There are multiple reflux pipes 4, which are distributed circumferentially along the outlet pipe 3. One end of each reflux pipe 4 is connected to and communicates with the outlet pipe 3, and the other end of each reflux pipe 4 is connected to the side wall of the separator body 8. The reflux pipe 4 communicates with the cavity. The connection position of the reflux pipe 4 and the separator body 8 is lower than the lower edge of the overflow port 9, so that the oil and part of the evaporator liquid flow into the outlet pipe 3 through the overflow weir and then flow back into the cavity through the reflux pipe 4 to participate in evaporation and separation again.

[0030] Optionally, each return pipe 4 is equipped with a valve, and the flow rate and velocity of the medium in the return pipe 4 can be adjusted by adjusting the opening of the valve.

[0031] Furthermore, this evaporator separator also includes a diversion pipe and a collection device (not shown in the figure). One end of the diversion pipe is connected to the return pipe 4, and the connection position between the diversion pipe and the return pipe 4 is close to the upper end port of the return pipe 4. By reducing the opening of the valve, the flow rate of the medium in the return pipe 4 is slowed down, so that the oil can float on the surface of the evaporating liquid in the return pipe 4. As the liquid level in the return pipe 4 rises, the oil and a small amount of evaporating liquid flow out through the diversion pipe, and most of the evaporating liquid flows into the cavity through the return pipe 4.

[0032] The collecting device is connected to the end of the diversion pipe furthest from the return pipe 4. The oil and a small amount of evaporated liquid overflowing from the diversion pipe flow into the collecting device for unified collection so that they can be processed later.

[0033] Furthermore, the turbulence device includes a rod 7 and a turbulence section. The rod 7 is coaxially arranged with the separator body 8, and the turbulence section is perpendicular to the rod 7. Preferably, the turbulence section includes a first scraper 1 and a second scraper 6 extending radially along the separator body 8. The turbulence device also includes a drive motor, which is connected to the end of the rod 7 away from the turbulence section. Both scrapers are located inside the liquid level limiting ring 2, and both scrapers are located near the upper end port of the liquid level limiting ring 2. When the drive motor is started, the drive motor drives the rod 7 to rotate the two scrapers, increasing the disturbance to the surface of the evaporating liquid inside the liquid level limiting ring 2, accelerating the overflow of oil, and preventing oil from accumulating on the surface of the evaporating liquid.

[0034] Alternatively, the turbulence device may specifically be a skimmer commonly found in the prior art, which in this embodiment operates at a slower speed.

[0035] In summary, the evaporator separator provided in this application can continuously discharge floating oil from the gas-water interface to the outside of the separator body 8 during operation, avoiding oil accumulation that affects the evaporation effect of the evaporator separator. It does not require shutdown for oil drainage, reducing the number of shutdowns of the evaporator separator and improving the continuous operation cycle of the evaporator. In addition, the evaporator separator has a simple structure, reducing the manufacturing and maintenance costs of the evaporator separator, and also helps to reduce the footprint of the evaporator separator.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
