It is widely used in the fields such as food, medicine, commodity, veterinary drug, feed, agricultural chemicals.Trans-anethole production anisaldehyde, fennel can also be utilized
The products such as nitrile, anise alcohol, raspberry ketone, hexanoestrol.High-purity isolated product of anise-oil, wide application, added value is high, economy effect
Benefit is good.But by the not simple isolation technics of high-purity isolated product of anise-oil can reach.In trans-anethole production procedure
In, water-oil separating is usually first carried out, places into freezing and crystallizing in freezer, finally crushes centrifugal vacuum rectifying, obtains trans-anethole production
Product.
At present, the process units structure of trans-anethole rectifying section is as shown in Fig. 2 including rectifying column, condenser, collecting tank, extraction
Vacuum mechanism, extracts vacuum mechanism and whole device now is extracted into vacuum, then fed intake to rectifying column, and it is cold that condenser is entered after rectifying
It is solidifying, discharge after collecting tank is finally entered, this structure distillation has following defect：Volume be 400L collecting tank, bottom 120L
Can't see liquid level, and fraction seperation is critical that to have 30L be mixed liquor, thus operating personnel can not accurately hold discharge when
Between, discharge influences the purity of trans-anethole in advance, postpones discharge waste of resource, and collection tank volume is larger, and it is larger to extract vacuum needs
Energy consumption；In rectifying, condensed water enter condenser condensing heat-exchange it is latter as be directly discharged into circulating water pool, waste the energy, and trans-anethole
Congealing point be 21.2 DEG C, and winter temperature reduces, and trans-anethole easily freezes in drainage conduit, influences the discharge of trans-anethole, reduces production effect
Rate.
The content of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of process units of trans-anethole rectifying section, the present apparatus is cold
Drainage conduit is directly set on condenser, without the collecting tank of existing structure, on the one hand can accurate discharge, ensure the high-purity of trans-anethole,
On the other hand the wasting of resources is also prevented from, reduces energy consumption, the outer surface of drainage conduit is also wrapped on condensed water thermal insulation casing, both improves energy
The utilization rate in source, while prevent trans-anethole from freezing, ensure the normal discharge of device, improve production efficiency.
In order to achieve the above object, the technical scheme that the present invention takes：
The process units of trans-anethole rectifying section, including rectifying column, the condenser being connected successively with rectifying column by pipeline, extract
Vacuum mechanism, the condenser side is connected with condensed water inlet pipe, opposite side is connected with condensed water outlet pipe, the bottom of the condenser
End is connected with drainage conduit, and the upper end outer surface of the drainage conduit is coated with condensed water thermal insulation casing, and the bottom of the drainage conduit is set
There is discharging opening valve, the condensed water thermal insulation casing is connected with the condensed water outlet pipe.
As optimal technical scheme, in order that the pressure in drainage conduit is more than atmospheric pressure, ensure the smooth discharge of drainage conduit,
Production efficiency height is further ensured that, the lower end of the drainage conduit is provided with a pressure maintaining pipe, and the pressure maintaining pipe is in perpendicular folded structure.
As optimal technical scheme, in order to ensure whole process units all in vacuum state, it is ensured that the pressure of drainage conduit
Superatmospheric is strong, can smooth discharge, efficiently production, the top of the drainage conduit and the vertical height of bottom are more than or equal to
11.7m。
Compared with prior art, the device have the advantages that：
1st, the present apparatus directly sets drainage conduit on condenser, without the collecting tank of existing structure, on the one hand can accurately arrange
Material, ensure the high-purity of trans-anethole, be on the other hand also prevented from the wasting of resources, reduce energy consumption, the outer surface of drainage conduit is also wrapped on cold
Condensate thermal insulation casing, had both improved the utilization rate of the energy, while prevented trans-anethole from freezing, and ensured the normal discharge of device, improved production effect
Rate.
2nd, it is in the pressure maintaining pipe for erecting folded structure to set, and the pressure in drainage conduit is more than atmospheric pressure, prevents thing when rectifying finishes up
Material deficiency causes air-flow suck-back, ensures the smooth discharge of drainage conduit, further ensures that production efficiency height.
3rd, the vertical height of the top of drainage conduit and discharging opening is more than or equal to 11.7m, ensure whole process units all in
Vacuum state, it is ensured that the pressure superatmospheric of drainage conduit is strong, can smooth discharge, efficiently production.
