Abstract
The invention discloses a kind of vegetable insulating oil decoloration process, it is characterised in that comprise the following steps: (1) opens vacuum pump, maintain vacuum at 30 50mmHg, open steam control valve bleacher is preheated, open bleacher guard filter and install filter bag additional so that it is keep duty；(2) open bleacher front pump, start bleacher front pump and vegetable insulating oil deep for color and luster is injected bleacher, vegetable insulating oil is heated to 105 to 110 DEG C；Active hargil and the activated carbon of 0.3 0.5% by the 3 5% of oil mass suck in bleacher；(3) bleacher agitating device is opened；(4) start bleached oil drawing pump, the vegetable insulating oil after absorption is injected vertical blade filter and filters, it is thus achieved that clean vegetable insulating oil；Start bleached oil oil transfer pump and bleached oil is injected next workshop section.The clean vegetable insulating oil that this technical scheme obtains, color clear, some trace metal ions that can remove in colloid in oil, effectively removing vegetable insulating oil.
Description
Technical field
The present invention relates to vegetable oil and insulating oil refining art, particularly to a kind of oil utilizing vegetable oil preparation insulation
Decoloration process.
Background technology
Vegetable insulating oil is a kind of environmental protection liquid dielectric, is generally considered the good replacement of mineral insulating oil
Product.The U.S.'s existing tens thousand of vegetable insulating oil distribution transformers so far run.Further, U.S. Cooper company research worker is
The application of hands research 1000kV vegetable insulating oil transformator.In China, State Grid Corporation of China, Southern Power Grid Company are proposed green
Color power grid construction target, First has the vegetable insulating oil distribution transformer 2010 of independent intellectual property right in Henan power saving
Net company hanging net operation, Southern Power Grid Company has set up the project and has developed 110kV electric pressure macrophyte insulating oil power transformer.
The main component of vegetable insulating oil is triglyceride, and its molecular structure is the most asymmetric, containing hydroxyl in molecule
With carbonyl isopolarity group, containing pigment different in quantity and product in common each vegetable oil, present different
Color.In vegetable oil, the source of pigment is broadly divided into three classes: the first kind is organic pigment, mainly chlorophyll, carotenoid,
Possibly together with special pigment in indivedual oils and fatss；Equations of The Second Kind is organic degradation thing, i.e. protein in quality deterioration oils and fats, saccharide, phosphorus
The degradation product of the compositions such as fat.3rd class is chromogen, and chromogen is the most colourless, oxidized after can present distinctness face
Color.Through the vegetable insulating oil of desolventing technology, can not only color clear, colloid in oil can also be removed, and can have
Some trace metal ions in effect ground removing vegetable insulating oil, thus the further refine for vegetable insulating oil provides good
Condition.Accordingly, it would be desirable to develop a kind of decolorizing process technique for novel plant insulating oil.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of color clear, can remove colloid in oil, effectively takes off
Vegetable insulating oil decoloration process except some trace metal ions in vegetable insulating oil.
For solving above-mentioned technical problem, the technical scheme is that, this vegetable insulating oil decoloration process includes following step
Rapid:
(1) vegetable insulating oil is heated to 105 to 110 DEG C, adds the active hargil of 3-5% of oil mass and 0.3-0.5%
Activated carbon, keeping vacuum is that 30-50mmHg bar 30-60 r/min stirs 40-60 minute；
The major advantage of above-mentioned steps: select hargil as adsorbent, there is higher activity the most afterwards and absorption is held
Amount, it is possible to the effectively pigment composition in removing vegetable insulating oil and some polar impurity, reduces the loss in decolorization.This
Outward, active hargil does not reacts with triglyceride, it is to avoid after decolouring, vegetable insulating oil component changes and stability reduces；
(2) being filtered by the vegetable insulating oil suction vertical blade filter after absorption, the circulation fine straining time is about 3-simultaneously
6h, filters colloidal impurity and hargil, it is thus achieved that clean vegetable insulating oil；
The major advantage of above-mentioned steps: combine the features such as the pigment that vegetable insulating oil contains a greater number and kind, exhausted to plant
Edge oil carries out desolventing technology, has not only reached and has improved oil colours, the purpose of removing colloid, moreover it is possible to effectively in removing vegetable insulating oil
Trace metal ion, the further refine for vegetable insulating oil provides good condition.
Detailed description of the invention
Hereinafter the preferred embodiments of the present invention will be described in detail.Should be appreciated that preferred embodiment is only for saying
The bright present invention rather than in order to limit the scope of the invention.
Embodiment 1:
This vegetable insulating oil decoloration process comprises the following steps:
(1) open vacuum pump, maintain vacuum at 30-50mmHg, open steam control valve and bleacher is preheated, open
Bleacher guard filter installs filter bag additional so that it is keep duty；
(2) open bleacher front pump, start bleacher front pump and vegetable insulating oil deep for color and luster is injected bleacher, by plant
Insulating oil is heated to 105 to 110 DEG C；The active hargil of the 3-5% of oil mass and the activated carbon of 0.3-0.5% are sucked decolouring
In tank；
(3) opening bleacher agitating device, rotating speed controls at 30 60rpm, maintains oil temperature to 105-110 DEG C, is keeping true
In the case of sky continuously stirred 40-60 minute；
(4) start bleached oil drawing pump, the vegetable insulating oil after absorption is injected vertical blade filter and filters, circulation essence
The filter time is about 3-6h, filters colloidal impurity and hargil, treats hargil precoated shet molding in vertical blade filter, and oil clarification
After carry out fine straining, it is thus achieved that clean vegetable insulating oil；Start bleached oil oil transfer pump and bleached oil is injected next workshop section.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, it is clear that those skilled in the art
Member can carry out various change and modification without departing from the spirit and scope of the present invention to the present invention.So, if the present invention
These amendments and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these
Change and including modification.
