Volatile oil extraction separator

Abstract

The invention discloses a volatile oil extraction separator which is characterized in that a bent end is formed at the lower part of a buffer tube, the bottom of the bent end is connected with a measuring tube, an opening is formed in the top of the bent end, the opening in the side end part of the bent end is connected with a top port of a steam eduction tube, and a second condenser is arranged at the lower part of the measuring tube. According to the invention, the slide-shaped buffer tube is adopted, so that condensate drops slowly slide downwards along the side tube wall of the buffer tube, in the steam backflow process, the vertical falling speed of the condensate drops is reduced when the condensate drops pass through the buffer tube, the condensate drops horizontally flow into the measuring tube when passing through the bent end at the lower part of the buffer tube, and the vertical speed is very low when the condensate drops slide into the measuring tube; vortex flow generated when the volatile oil is vertically dripped into an oil layer is reduced, the stability of the oil layer is improved, and effective separation of volatile oil and water is achieved. The second condenser is arranged at the lower part of the measuring tube so that higher oil temperature in the upper oil layer can be ensured, the flowability of the oil layer is improved, precipitates in cold water move upwards and are gradually condensed and fused into the upper hot oil layer, and the oil yield of volatile oil can be improved by 10-40%.

Description

technical field [0001] The invention relates to a volatile oil extractor, in particular to a volatile oil extraction separator capable of effectively separating oil and water. Background technique [0002] Volatile oils, also known as essential oils, are mostly colorless or light yellow liquids with a relative density of less than 1. At present, in the classic extractor commonly used to extract volatile oils, during the condensation process, the oil and water vapor form droplets, which drop into the oil surface of the measuring tube in the form of free fall from the end of the condenser, destroying the stability of the oil-water layer interface in the measuring tube At the same time, directly dripping into the oil surface makes the oil-water droplets enter the lower water of the measuring tube due to inertia, causing the separated small oil droplets to suspend in the lower water or adhere to the wall of the measuring tube, resulting in incomplete oil extraction and greatly r...

At present, in the classic extractor commonly used to extract volatile oils, during the condensation process, the oil and water vapor form droplets, which drop into the oil surface of the measuring tube in the form of free fall from the end of the condenser, destroying the stability of the oil-water layer interface in the measuring tube At the same time, directly dripping into the oil surface makes the oil-water droplets enter the lower water of the measuring tube due to inertia, causing the separated small oil droplets to suspend in the lower water or adhere to the wall of the measuring tube, resulting in incomplete oil extraction and greatly reduced oil rate

[0003] In the volatile oil extraction separator disclosed in CN103992880A, although the phenomenon that volatile oil adheres to the inner wall of the measuring tube can be reduced, because the outside of the whole measuring tube is cooled by condensed water, the volatile oil stored in the measuring tube is affected by the external condensation pipe, and the temperature is relatively high. Low temperature causes the volatile oil to condense into a paste, which is difficult to suck out with a straw, which increases the difficulty of taking out the volatile oil; at the same time, the viscosity of the volatile oil essential oil after cooling increases, and it is easier to adhere to the glass wall, which affects the final oil yield.
