Problems solved by technology

However, due to the positive pressure inside the system during the steam distillation process, the reflux is easily blocked, resulting in a slower reflux rate and lower efficiency
[0004] In addition, CN202021517019.0 discloses a steam distillation device for increasing the yield of volatile oil. Its advantage is that a vacuum tank is added between the condenser and the oil-water separator, which can provide negative pressure conditions for the system and increase the yield of volatile oil. It is suitable for one oil phase, and the oil-water separator lacks visual devices such as sight glass and an attached reflux device, which has the defects of low degree of visualization, narrow application range, and poor reflux effect

Embodiment 1

[0027] A steam distillation device for effectively separating oil-water mixture, such as figure 1 Shown, comprise reactor 1, condenser 2, oil-water separator 3 and reflux tank 6, wherein reactor 1 top is provided with kettle cover 103, reactor 1 is provided with jacket 101, and jacket 101 is provided with steam outlet pipe 1011 and The steam inlet pipe 1012 is provided with a safety valve and a pressure gauge, and the bottom of the reaction kettle 1 is provided with a liquid outlet, and the liquid outlet is provided with a liquid outlet valve 102 . A breathing cap 602 is installed on the top of the return tank 6 . The connection relationship of several main components is as follows:

[0028] The top of the reaction kettle 1 is provided with a gas phase pipeline 1031 and connected to the condenser 2, the liquid outlet at the bottom of the condenser 2 is connected to the top of the oil-water separator 3 through the funnel 4 and the condensate pipeline 201, and the oil-water sep...

Embodiment 2

[0032] Further optimization can be carried out on the basis of Embodiment 1, such as figure 2 , 3 As shown, a visible glass tube 5 is provided on the condensate pipeline 201, and the side of the visible glass tube 5 is connected to the first outlet valve 501 through a pipeline, and the visible glass tube 5 and the pipeline of the first outlet valve 501 are provided with The first viewing mirror 701 is convenient for observation and sampling of condensate. A control valve 2011 is provided on the condensate pipeline 201 between the sight glass tube 5 and the oil-water separator 3 .

[0033] The bottom of the oil-water separator 3 is connected to the second outlet valve 301 through a pipeline, and a second sight glass 702 is arranged on the pipeline between the oil-water separator 3 and the second outlet valve 301 to facilitate observation of the separation state of the oil-water mixture.

[0034] One side of the reflux tank 6 is connected to the reflux pipeline 601 through a ...

Embodiment 3

[0036] On the basis of Embodiment 1 and Embodiment 2, the present invention is equipped with a manual crane 8 on one side of the reactor 1 for hoisting the internal hopper of the reactor 1 . A pressure gauge and a safety valve are arranged on the top of the kettle cover 103 to ensure safe use.

[0037] The concrete use process of the present invention is as follows:

[0038] Before work, close the reactor liquid outlet valve 102, turn the manual crane 8 to open the reactor lid 103, add water once, cover the kettle lid 103 and tighten the fasteners, open the steam inlet valve and the outlet valve, and heat up the water once. When the condensate pipeline 201 at the lower end of the condenser has condensate flowing out, observe the clarity of the liquid through the sight glass tube 5 and the first sight glass 701 until the system is cleaned and qualified, stop heating, close the steam valve, and open the liquid valve 102 , discharge waste water.

[0039]When working, close the ...

Abstract

The invention discloses a steam distillation device for effectively separating an oil-water mixture, which belongs to the field of essential oil extraction and comprises a reaction kettle, a condenser and an oil-water separator which are connected in sequence, and a return tank with a breathing cap at the top is arranged between the oil-water separator and the reaction kettle. The return tank is respectively connected with the oil-water separator and the reaction kettle through a return pipeline and a water replenishing pipeline, and the oil-water separator is respectively connected with the return pipeline through an upper valve and a lower valve which are arranged up and down. The method is suitable for separating two conditions that the oil phase is lighter than the water phase and the oil phase is heavier than the water phase, and the application range is wider.

Description

technical field [0001] The invention relates to the field of essential oil extraction, in particular to a distillation device for separating oil-water mixture. Background technique [0002] The traditional plant essential oil extraction device is mainly composed of three parts: a reactor, a condenser and an oil-water separator. The materials and water are heated in the reactor, and the water vapor and volatile essential oil enter the condenser through the gas phase pipeline, condense into a liquid oil-water mixture, and flow into the condenser. To the oil-water separator to realize the separation of essential oil and water. [0003] The general essential oil extraction device is only suitable for one of the separated oil phase is lighter than the water phase or the separated oil phase is heavier than the water phase, but there are very few devices that meet the above separation functions at the same time, and in the general steam distillation device , the oil-water separato...
