First embodiment
The present embodiment provides a temperature change oil-water separator 100, which is shown with reference to fig. 1, and includes a housing 110 and a separation chamber 120 located within the housing 110.
As shown in fig. 1, in the present embodiment, the housing 110 is entirely cylindrical, and a light oil separator 111 is provided at the top of the housing 110 and a heavy oil separator 112 is provided at the bottom. The separation chamber 120 includes a first separation chamber 121 at an upper portion of the housing 110, and a second separation chamber 122 at a lower portion of the housing 110. The mixed oil feed pipe extends through the housing 110 into the first separation chamber 121 and the aqueous phase discharge pipe 114 extends through the housing 110 into the second separation chamber 122. A condensing sleeve 130 is sleeved at a position corresponding to the second separation chamber 122 outside the shell 110, and a condensing cavity 131 for passing condensate is formed between the condensing sleeve 130 and the shell 110.
An oil-water mixture formed by the volatile oil and the condensed water enters the first separation chamber 121 through the mixed oil feed pipe, and light oil in the oil-water mixture rises and is collected by the light oil separator 111 positioned at the top of the first separation chamber 121. The heavy oil and water are sunk together into the second separation chamber 122 and further separated in the sinking process, the separated heavy oil is collected by the heavy oil separator 112 at the bottom of the second separation chamber 122, and the condensed water is discharged from the water phase liquid outlet pipe 114. However, the densities of heavy oil and water are close, and a long time is required for separation to be achieved. In the embodiment, the heavy oil and the water are cooled again in the process of sinking the heavy oil and the water, so that the density difference of the heavy oil and the water is increased, and the heavy oil and the water are easier to separate. It should be noted that, in the present embodiment, there is no real separation between the first separation chamber 121 and the second separation chamber 122, and the first separation chamber 121 and the second separation chamber 122 are still substantially a complete whole, and the second separation chamber 122 is merely a functional distinction based on the effect of cooling again.
The condensation chamber 131 is provided with a condensate inlet 132 and a condensate outlet 133, the condensate inlet 132 being located at the bottom of the condensation chamber 131 and the condensate outlet 133 being located at the top of the condensation chamber 131. The condensate moves from bottom to top, and forms countercurrent with the mixture of heavy oil and water, thereby achieving the purpose of improving the cooling effect.
The condensation chamber 131 is disposed along the circumference of the housing 110 and surrounds the housing 110 for a circle, so that the condensate can uniformly cool the mixed liquid in the second separation chamber 122 from all directions of the housing 110, and the separation effect is increased.
The condensing jacket 130 is made of an insulating material. The condensing cover 130 made of heat insulating material can prevent cool air from overflowing, so that condensate can better transfer heat with the shell 110, and the cooling efficiency of mixed liquid in the second separation chamber 122 is improved.
The top of the housing 110 is provided with a respirator 115. The breather 115 can be used to balance the air pressure in the separation chamber 120 to avoid situations such as poor separation and backflow caused by negative pressure, or situations such as liquid spraying and leakage caused by excessive pressure.
Second embodiment
The present embodiment provides a temperature change oil-water separator 200, which is substantially the same as the temperature change oil-water separator 100 provided in the first embodiment with reference to fig. 2, with the following differences.
In order to further improve the cooling efficiency, as shown in fig. 2, the temperature-changing oil-water separator 200 in this embodiment is further provided with a condensation pipe 140, where the condensation pipe 140 includes a liquid inlet pipe 141, a spiral pipe 142 and a liquid outlet pipe 143, the spiral pipe 142 is located in the second separation chamber 122 and is disposed around the water phase liquid outlet pipe 114, two ends of the spiral pipe 142 are respectively communicated with the liquid inlet pipe 141 and the liquid outlet pipe 143, and the liquid inlet pipe 141 and the liquid outlet pipe 143 penetrate through the housing 110. The condensation tube 140 can extend into the second separation chamber 122 to cool the mixed liquid in the second separation chamber 122, and can greatly increase cooling efficiency when being matched with the condensation chamber 131.
Further, as shown in fig. 2 and 3, in the present embodiment, the temperature-variable oil-water separator 200 further includes a cyclone separator 150, the cyclone separator 150 is located in the first separation chamber 121, an inflow port 151 of the cyclone separator 150 is communicated with the mixed oil feed pipe 113, an overflow port 152 is provided at the top of the cyclone separator 150, and a bottom flow port 153 is provided at the bottom. The cyclone 150 can primarily separate the oil-water mixture, and under the action of centrifugation, the light oil flows out from the overflow port 152 at the top of the cyclone 150, while the heavy oil and water flow out from the bottom flow port 153 at the bottom of the cyclone 150.
The cyclone separator 150 is provided therein with a cyclone chamber 154, the cyclone chamber 154 including a cylindrical cyclone chamber 1541 located above and a conical cyclone chamber 1542 located below, the inlet 151 of the cyclone separator 150 being disposed along a tangential direction of the cylindrical cyclone chamber 1541. The tangentially entered oil-water mixture moves in a spiral shape, and after entering the conical section swirl chamber 1542, the liquid rotation speed is gradually increased along with the gradual reduction of the inner diameter. Because of the smaller caliber of the bottom flow port 153, liquid cannot be completely discharged from the bottom flow port 153. In this case, heavy oil and water flow out from the bottom flow port 153 along the wall of the cyclone chamber 154, and the light oil is pressed upward toward the center of lower pressure, and flows out from the overflow port 152, so that the primary separation of the light oil is realized.
Further, as shown in fig. 2 and 4, a spoiler 160 is disposed below the bottom flow port 153, and the spoiler 160 is connected with the housing 110 and is spaced from the bottom flow port 153 of the cyclone separator 150; a liquid passing gap 161 is provided between the spoiler 160 and the housing 110. The movement speed of the heavy oil and water flowing out of the bottom flow port 153 is high, and after flowing into the second separation chamber 122, sufficient stay cooling cannot be achieved. The spoiler 160 can play a better role in buffering, heavy oil and water impact the spoiler 160, and after being blocked and decelerated, the heavy oil and water flow into the second separation chamber 122 through the liquid passing gap 161 to sufficiently cool down, so that the separation effect is improved.
The embodiment also provides a volatile oil extraction system, which comprises the variable-temperature oil-water separator 200. The variable-temperature oil-water separator 200 has high separation efficiency on oil-water mixtures and can improve the yield of volatile oil.
In summary, the embodiment of the application provides a temperature-variable oil-water separator, which can cool down the oil-water mixture again in the process of heavy oil falling after light oil is separated, so that the density difference between heavy oil and water is increased, and the separation is easier. The variable-temperature oil-water separator is simple to operate, high in separation efficiency and particularly suitable for volatile oil with light oil and heavy oil.
The embodiment of the application also provides a volatile oil extraction system which comprises the variable-temperature oil-water separator, has high separation efficiency on an oil-water mixture and can improve the yield of volatile oil.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
