Background technology
Crude oil refers to being produced from animal or vegetable oil material, not by the primary oil of refining processing.Crude oil is due to processing work
Skill is simple, and this oil is impure more, oxidizable rotten, unsuitable long term storage.
Crude oil is flowed out from crude oil tank first in refining process, is gone using centrifuge after heating tank heats
Except impurity removes stink finally by deodorization tank.Wherein, deodorization mainly removes those in crude oil and is allowed to generate foreign odor and peculiar smell
Impurity.The impurity of removing generally includes free fatty；The compound for causing foreign odor and peculiar smell, such as aldehyde, ketone, alcohol and hydro carbons；With
The compound generated due to peroxide and pigment thermally decompose.These impurity, which should be removed fully just, can make edible oil have expection
Property.For example, the aliphatic acid in edible oil should substantially be reduced to about 0.1%-0.2%, it can just obtain that there is expected property
Edible oil.
Crude oil deodorization is typically in the presence of a kind of inert gas such as steam or nitrogen, under a high vacuum, in hot conditions
Lower progress.When inert stripping gas undesirable impurity of stripping from crude oil, hot conditions promote undesirable impurity
Thermal decomposition.High vacuum prevents oxidative degradation of the crude oil during deodorization.
Once deodorization is completed, the hot deodorization edible oil being formed by just is cooled.It is known at high temperature, deodorization eats oil pole
Oxidative degradation easily occurs.Therefore, by cooling, deodorization edible oil is made to be preferably minimized limit to the sensibility of oxidation.
Cooling usually carries out in a heat recovery units, and hot deodorization edible oil provides under vacuum at this time.Heat
Recovery unit can be the important component that may not be deodorizing apparatus, its operation be in order to by using wait for deodorization into
Crude oil is expected as indirect cooling way, from just recycling heat in the deodorization edible oil of blowdown.Heat is recycled by using crude oil,
The deodorization edible oil of heat can reach the desired temperature for being respectively adapted to storage and deodorization with crude oil simultaneously.However, using a kind of
Pipe-the shell heat exchanger commonly used is come to reach above-mentioned purpose be particularly undesirable, because being usually the pressure drop overcome in heat exchanger
And the outer mechanical pump needed may cause gas leakage, to make the hot deodorization edible oil oxidation under vacuum.
Therefore, it is desirable that finding the method that deodorization eats oil-proofness that can improve, that is, it is less susceptible to that oxidative degradation occurs,

The stripping of crude oil is more abundant.
Further, the one end of the air inlet pipe far from tank body is connected to nitrogen gas tank, and the air inlet pipe is equipped with air valve.
By using above-mentioned technical proposal, air valve can control the flow velocity of the nitrogen exported in nitrogen gas tank.
Further, drier is equipped in the air inlet pipe between nitrogen gas tank and air valve.
By using above-mentioned technical proposal, drier can remove the moisture in nitrogen, avoid the impurity in moisture and moisture
It brings into crude oil.
Further, the tank base is communicated with blowdown pipe, and the blowdown pipe lower end is connected to blow down container.
By using above-mentioned technical proposal, the material flowed out in reative cell in tank body can be discharged in discharge duct.
Further, the top of the tank is communicated with the first vacuum pump, the gas outlet connection condensation of first vacuum pump
Device, the liquid outlet of the condenser are connected to condensate liquid recycling can, and the gas outlet of the condenser is connected to the second vacuum pump, and described the
The gas outlet of two vacuum pumps is communicated with outside air.
By using above-mentioned technical proposal, the nitrogen being discharged out of tank body obtains condensate liquid by condenser, condenses liquid stream
Enter the impurity that condensate liquid recycling can avoid in condensate liquid to be discharged directly to the external world and cause environmental pollution, by condensed nitrogen
Outside air is then immediately discharged to by the second vacuum pump.
In conclusion the utility model has the advantages that：The reative cell of oil inlet pipe the top out of tank body flows into,
The nitrogen being passed through simultaneously by air inlet pipe.When the undesirable impurity of nitrogen stripping from crude oil, and carried out with the crude oil of heat
Heat exchange reduces the temperature of crude oil, can prevent crude oil from going out smelly period oxygenolysis to a certain extent.Crude oil in reative cell
Overflow to reative cell below carries out out that removing is smelly again, and crude oil is after the deodorization of multiple reative cells from the reaction of bottom
The flowline of room flows out, and obtains the edible oil with expected property.Crude oil is less susceptible to that oxidative degradation occurs, and can improve heat and remove
