Duplex type oil-water separator

Abstract

The invention discloses a duplex type oil-water separator. The duplex type oil-water separator comprises a first oil-water separator and a second oil-water separator, wherein the lower part of the first oil-water separator is communicated with the lower part of the second oil-water separator through a connecting pipe; the first oil-water separator comprises a first separator cylinder, a first topcover is arranged at the upper end of the first separator cylinder, a feed port is formed in the first top cover, a first heavy oil discharge port is formed in the lower end of the first separator cylinder, a light oil collecting pipe is arranged in the first separator cylinder, an oil inlet of the light oil collecting pipe is formed in the upper part of the first separator cylinder, and an oil outlet of the light oil collecting pipe extends out from the bottom of the first separator cylinder and is communicated with a light oil collecting device. According to the duplex type oil-water separator, not only can light oil in an oil-water mixture be separated sufficiently, but also heavy oil in the oil-water mixture can be separated sufficiently, resource waste can be avoided, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of oil-water separators, in particular to a double-connected oil-water separator. Background technique [0002] Some Chinese herbal medicines themselves have aroma, and the aromatic oils of the medicinal materials need to be collected during the production process of Chinese herbal medicines, and the aromatic oils need to be added to the final product. So whether the aromatic oil can be well collected and separated during extraction cannot be underestimated, because it is directly related to the grade of the product. [0003] After extracting and collecting volatile oil from traditional Chinese medicine, the oil-water mixture in the form needs to be separated by an oil-water separator. However, the existing oil-water separator usually takes advantage of the characteristics of light oil and heavy water, with oil coming out from the top and water coming out from the bottom. However, some oil-water mixtures no...

AI Technical Summary

Problems solved by technology

However, some oil-water mixtures not only contain light oil that is lighter than water, but also heavy oil that is heavier than water. These heavy oils sink under the water and cannot be extracted through the discharge port on the upper part of the separator cylinder. The sewage outlet is discharged together with the magazine, resulting in waste of resources and low product yield; in addition, the existing oil-water separator can only separate the oil-water mixture once, and the water discharged from the outlet after the first separation still contains some Unseparated heavy oil completely separates heavy oil, wastes resources, and brings great inconvenience to the separation of oil-water mixture
