[0005] 2. After the mixed liquid is left to stand, the impurities in it are released together with the high-density liquid, which affects the purity of the high-density liquid, and the low-density liquid will inevitably be mixed with impurities, and the purity is difficult to guarantee;
[0006] 3. When using the separator for separation, it involves the transfer of the mixed liquid, and it cannot be carried out directly in the container containing the mixed liquid, which is inconvenient to operate, and because the mixed liquid will be stirred after feeding, therefore, each time the mixed liquid is transferred After the liquid is removed, it must be allowed to stand for a period of time, which takes a long time
[0007] In addition, in the prior art, an important step in the process of extracting spice oleoresin from spices is to separate the volatile oil from the water in the mixture of volatile oil and water obtained by distillation, because the mixture will inevitably be mixed with solid suspension Substances such as raw spice fine powder, etc., when using the existing oil-water separator for separation, this part of the suspended matter is difficult to remove from the volatile oil, and the effect of oil-water separation is not good. To improve the purity of the separated volatile oil, it will lead to more The loss of more volatile oil; and to reduce the loss of volatile oil, the purity of volatile oil will decrease

Embodiment 1

[0026] This embodiment provides an oil-water separator. Such as figure 1 and 2 As shown, the oil-water separator includes a base 1 , a collector 2 fixedly supported by the base 1 , a filter screen 3 surrounding the periphery of the collector 2 , and an extraction device 4 for extracting liquid in the collector 2 .

[0027] The collector 2 has a collector body 20 in the shape of a barrel and a central groove 21 formed by a downward depression at the center of the collector body 20. When separating, oil with a lower density flows from the upper end of the side wall of the collector body 20. The edge overflows in and finally flows into the central groove 21 . The bottom surface of the central groove 21 is arc-shaped. The lower end of the oil outlet pipe 41 of the extraction device 4 is correspondingly inserted into the central groove 21, and under the action of the oil pump 40, the oil in the central groove 21 is drawn away. The filter screen 3 is set on the outer periphery o...

Embodiment 2

[0031] A method for separating peppercorn essential oil from a mixture of peppercorn essential oil extracted by steam distillation and water, the specific process is as follows: after the mixture is layered, insert the oil-water separator of Example 1 into it, and adjust the connecting rod 11 The height makes the upper end of the side wall of the collector body 20 be in the position between the liquid level of the mixed liquid and the interface, so that after the prickly ash essential oil on the upper layer is filtered out solid suspended matter through the filter screen 3, it will flow from the side wall of the collector body 20 The upper end overflows into the collector body 20, and finally the oil well pump 40 is drawn away from the collector body 20 to realize oil-water separation. After testing, the purity of the pepper essential oil can reach more than 90%, does not contain solid suspended impurities, and the loss rate of the pepper essential oil is less than 1%.

Abstract

The invention relates to an oil-water separator for separating two-phase mixed liquid and a method for separating volatile oil and water by utilizing the separator. The separator is particularly suitable for the oil-water separation in two-phase liquid containing more solid suspended matters and comprises a base, a collector, a filter screen and an extracting device, wherein the base is suspended in two-phase mixed liquid; the collector is fixed and supported by the base and used for collecting low-density liquid; the filter screen surrounds the collector; the extracting device is used for extracting the liquid in the collector; the collector is provided with a barrel-shaped collector body; and the upper end of the side wall of the collector body is positioned between the liquid level and the interface of the two-phase mixed liquid or the side wall of the collector body is provided with an overflow opening, and the lower end surface of the overflow opening is positioned between the liquid level and the interface of the two-phase mixed liquid. The invention has simple installation and operation and good separating effect.

Description

technical field [0001] The invention belongs to the technical field of liquid separators, in particular to a separator for two liquids with different densities and easy phase separation. The invention also relates to a method in which the separator is used for separating volatile oil and water. Background technique [0002] Oil-water separators are widely used in the chemical industry, automobile industry, petrochemical industry and sewage treatment industry. According to the different specific gravity of different liquid phases in the mixed liquid, the mixed liquid is stratified by means of filtration, sedimentation, and floating. Thus, liquid phase separation is carried out. [0003] In the prior art, the oil-water separator mainly includes a separator body with a separation chamber, a feed pipe for sending the mixed liquid into the separation chamber, and a low-density liquid overflow port is arranged above the side wall of the separator body. A high-density liquid outl...
