Description
Technical Field
The invention relates to an oil-water separation device for extracting volatile oil by a steam distillation method.
Background
The steam distillation method is the most common continuous dynamic extraction method of volatile oil, has the advantages of simple structure, simple and convenient operation, high efficiency, no pollution, no solvent residue in the prepared volatile oil and the like, and is widely applied to actual production.
The oil-water separator is a core component in the process of preparing volatile oil by a steam distillation method, and the oil-water separation effect is one of the main factors influencing the oil yield. The gravity settling oil-water separation method is a traditional and economic oil-water separation method, realizes the separation of volatile oil and water by utilizing the incompatibility and density difference between oil and water and through the mutual collision and aggregation of oil droplets with different particle diameters in a static or flowing state, and has the advantages of simple structure, small flow resistance, capability of treating large-flow oil-water mixtures and the like.
In the existing gravity settling oil-water separator, an oil-water mixture is generally vertically guided into a separation chamber by a guide pipe for separation. However, in the practical application process, the oil-water mixture in the separation chamber is disturbed because the oil-water mixture still has a higher initial speed when flowing out of the inlet pipe; meanwhile, a large amount of oil droplets are flushed into the bottom of the separation chamber along with water flow, so that the rising time of the oil droplets is increased, the wall sticking is increased, and a part of the oil droplets enter a return pipe along with the water flow and return to a distillation device or enter extracted fresh flower dew, so that the oil recovery rate is greatly reduced.
Disclosure of Invention
The invention provides an oil-water separation device with a guide plate, which is used for improving the oil-water separation efficiency and the oil yield.
The oil-water separator with the guide plate comprises an oil-water separator and is characterized in that the oil-water separator is of a conical structure, the guide plate is arranged at the outlet end of an inlet pipe of the oil-water separator, the guide plate is in a segmental shape, the guide plate is fixedly connected with the inner wall of the inlet pipe through a rod-shaped body, an adjusting pipe is arranged at the lower part of the inlet pipe, the adjusting pipe is screwed or clamped with the inlet pipe, an oil taking port is formed in the upper part of the oil-water separator, a condensing pipe and a return pipe are respectively arranged at the bottom of the oil-water separator, and the return pipe is connected with a distillation chamber of the distiller after passing through a U-shaped pipe.
The diameter of the guide plate is 1.5-3 times of the inner diameter of the guide pipe.
The invention achieves the technical progress that:
the invention solves the practical problems of low oil-water separation efficiency and large loss of volatile oil in the prior production by arranging the relative adjustable guide plate, the secondary condenser pipe and the oil-water separator with the conical structure, and particularly obviously improves the separation and collection of the volatile oil with low oil yield. Experiments prove that after the oil-water mixed liquid at the temperature of 30-40 ℃ enters the inlet pipe, the oil-water mixed liquid is guided by the segmental structure guide plate at the outlet end of the inlet pipe and then radially enters the conical oil-water separator for oil-water separation. After the oil-water mixed liquid with higher temperature enters the separator, the surface tension of oil droplets is favorably reduced, the collision coalescence capability is enhanced, oil drops in the mixed liquid form floatable oil as soon as possible, meanwhile, the solidification and adhesion of viscous volatile oil can be avoided, and the collection rate is improved.
Because the regulating tube is screwed or clamped at the lower part of the leading-in tube, the outlet at the bottom of the regulating tube can keep a proper vertical distance with the guide plate by regulating the height of the regulating tube, so that the mixed liquid is more uniformly distributed on the guide plate in the radial direction when flowing out, and the oil-water separation operation of oil-water mixture materials with different viscosities and different flows is adapted.
The guide plate with the segmental structure can impact the flow direction of the mixed liquid from vertical to downward, and is guided to be uniformly distributed on the whole section along the radial direction of the segmental guide plate and slowly move downward, so that the direct impact on the oil-water mixed liquid in the separator is eliminated, the phenomenon that part of the oil-water mixed liquid returns to a distillation device or enters fresh flower dew without being separated is avoided, and oil drops can be effectively prevented from being accumulated at the bottom of the guide plate.
The tapered oil-water separator at the outlet end of the inlet pipe has a larger cross section, so that the flow rate of oil-water mixed liquid is reduced, the oil-water separation time is prolonged, and meanwhile, the smaller volatile oil storage layer surface at the upper part of the tapered oil-water separator is more favorable for collecting volatile oil with lower oil yield.
Because the bottom of the conical oil-water separator is provided with the condenser pipe, the liquid which is about to return to the distillation device or enter the fresh flower dew can be cooled, the oil/water emulsification rate is reduced, and some substances which are insoluble or slightly soluble in cold water and easily soluble in hot water are further separated out at the position, so that the loss of effective components is reduced, and the increase of the components of the volatile oil is facilitated.
The invention can continuously and efficiently separate and collect the volatile oil extracted by the steam distillation method, maintains the advantages of simple structure, easy operation and the like of a separation chamber of the traditional oil-water separator, has the characteristics of high separation efficiency, good continuity and low cost for oil-water mixed liquid with lower volatile oil content, is easy to disassemble and replace, can be generally compatible with steam distillation equipment used in the prior production, and is suitable for popularization and application.

The oil-water mixture that condenses to 30 ~ 40 ℃ collects the back via inlet tube 5, the 5 bottom export of inlet tube through the immersion liquid level flows perpendicularly in toper oil-water separator 3, the relative position of 5 bottom exports of inlet tube and guide plate 2 is adjusted to rotatory regulating tube 8, oil-water mixture moves down under the action of gravity and receives and block behind the guide plate 2, along the horizontal evenly distributed back of guide plate 2 radial direction at whole liquid level, the slow motion downwards, prevent that oil-water mixture from directly rushing into lower floor low temperature region and leading to the drop in temperature of oil, surface tension increases and scatters, the wall glues. Due to the cooling effect of the condenser pipe 1, the liquid on the bottom layer in the oil-water separator 3 further separates out the volatile components dissolved therein and floats to the upper layer. Because the density of the volatile oil is lower than that of water, oil droplets float to the upper liquid level while colliding and coalescing to form an oil-water separation layer, after an oil layer with a certain thickness is accumulated, the volatile oil can be discharged through the oil taking port 4 and collected by opening the flow guide valve, the inlet end of the return pipe 6 is positioned at the circle center of the bottom of the conical oil-water separator 3, and the oil layer in the conical oil-water separator 3 can be kept at the height of the oil taking port 4 all the time under the action of the U-shaped pipe.
