Oil-water separation device and method for simultaneously extracting light volatile oil and heavy volatile oil

Abstract

The invention discloses an oil-water separation device and method for simultaneously extracting light volatile oil and heavy volatile oil. The device comprises an extraction tank, a condenser and a volatile oil separator. The condenser can be vertically or obliquely mounted, the top of the condenser is emptied, and the part between the extraction tank and the condenser is subjected to heat preservation setting, so that the problem that the conventional volatile oil extracting device is relatively low in volatile oil collecting amount and cannot collect heavy volatile oil or collect light volatile oil and heavy volatile oil at the same time; the method for extracting light volatile oil and heavy volatile oil by utilizing the device is further disclosed, is simple, and high in volatile oil collecting amount, can use four types of organic solvents as trapping agents, is safe and non-toxic, and can quickly extract light volatile oil and heavy volatile oil at the same time.

Description

technical field [0001] The invention belongs to the field of volatile oil refining, and in particular relates to an oil-water separation device capable of simultaneously extracting light volatile oil and heavy volatile oil, and also relates to a method for simultaneously extracting light volatile oil and heavy volatile oil by using the device. Background technique [0002] Volatile oil, also known as aromatic oil, is a common sesquiterpene compound in plant tissues, which is extremely difficult to dissolve in water, but the aqueous solution of trace volatile oil at PPM level has a strong aromatic smell, so it is also called aromatic water. According to the relative density of volatile oil and water, the relative density lower than water is called "light oil"; the relative density higher than water is called "heavy oil". In the process of volatile oil extraction, the oil-water separation system of the multi-energy tank is generally used, but the heat exchange area of ​​the co...

AI Technical Summary

Problems solved by technology

In the process of volatile oil extraction, the oil-water separation system of the multi-energy tank is generally used, but the heat exchange area of ​​the condenser in the existing multi-energy tank oil-water separation system is generally small (generally 6m 3 The tank is only less than 3m 2 ), the tube wall of the condenser is too thick, which seriously affects the heat exchange efficiency, and the main condenser is horizontally placed, which affects the rapid replacement of oil-water condensate; the rising pipe from the evaporator to the main condenser has no heat preservation and condensate with slight pressure The impact on the oil-water liquid level of the oil-water separator leads to low collection efficiency of light and heavy volatile oils, and it is even impossible to collect volatile oils containing only heavy oil or heavy oil medicinal materials

But in essence, this does not fundamentally solve the problem of simultaneous extraction of light and heavy volatile oils

Moreover, the method of "collecting aromatic water" is bulky, and tons of aromatic water have problems in storage, transshipment, pollution prevention, and deterioration.
