Background technology
With the improvement of living standards, increasingly attention of the people to environment, this requirement just to various purifiers is got over
Come higher.Contain multiple pollutant, such as PM2.5, dust granules and division anaphylactogen in air, and much without popularity in air
Body is mostly waste gas sent off from automobiles, wherein being much to carry impurity in fuel oil to be discharged into together with exhaust gas in the case of unburned
In atmospheric environment, the service life of air quality and combustion apparatus is largely effected on.
Especially it is that can accelerate containing objectionable impurities, impurity presence such as sulphur, nitrogen, oxygen compound and trace meters in oil
The burn into of equipment influences the normal operation of equipment during use, reduces quality of oil product etc., lube purification is to concern national warp
The key areas of Ji, people's lives and national defense safety.Therefore, oil before use must purification and impurity removal.At present, petroleum cleanup skill
Art mainly has chemical method (addition chemical reagent etc.), heat treatment method, physical method (mechanical filter and electrostatic depuration).Chemistry
Method can remove part metals impurity, but be easily introduced new impurity and cause secondary pollution.Though heat treatment can reduce oil viscosity, carry
High flow rate, removes the gas in degreasing fluid, but it is higher with cost to consume energy.
Common carry out purification and impurity removal of the electrostatic technique to fluids such as air, oil at present, is utilized in DC Electric Field
The electrostatic field of lower generation, by the impurity absorption in fluid in dielectric material surface, realizes the separation of fluid and impurity.Traditional
If slab construction produces uniform electric fields by two tablets, by powered impurity absorption to pole plate and then removal of impurities is imitated
Fruit, does not then have sucking action but for the neutral impurity in liquid, so that the neutral impurity in degreasing fluid can not be removed, so
Clean-up effect is not fine.
Inhomogeneous field in order to obtain, we can add dielectric in the electric field, can also be used by structural change
Dielectric then needs to be replaced for a long time according to the flow of fluid, and impurity-eliminating effect is unstable, and financial cost is also higher, and use can produce
The cylindrical structure device of electric field heterogeneous, although inhomogeneous field can be produced, electric field strength and electric-force gradient it is big
