Description

Non-homogeneous electrostatic field efficient impurity removal equipment
Technical field
The invention belongs to fluid purifying apparatus field, and in particular to a kind of non-homogeneous electrostatic field efficient impurity removal equipment.
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 It is small all as the distance between central electrode to housing electrode strongly reduces, only in the electric field strength at the central electrode and Gradient is bigger, so to give play to preferable impurity-eliminating effect, it is necessary to applies very high electric field, so can then cause to flow through Under high electric field effect qualitative change occurs for the liquid of device, is so unfavorable for the safe to use of equipment.
The content of the invention
For solve above technical problem, enable a device to need not apply it is high-tension in the case of produce ladder heterogeneous Electric field is spent, the present invention provides a kind of non-homogeneous electrostatic field efficient impurity removal equipment.
To achieve the above object, technical scheme is as follows:
A kind of non-homogeneous electrostatic field efficient impurity removal equipment, includes the shell of cylindrical-shaped structure, which is powered to forming first Electrode, the shell lower end are equipped with import, and upper end is equipped with outlet, it is characterized by:An at least conduction is equipped with the shell Rod, the conductive rod are set along the axial direction of shell, which is powered to forming central electrode, and the conductive rod outer surface is uniformly distributed There are a conductive bumps, the conductive bumps extend radially outwardly along conductive rod and leave gap between outer casing inner wall.
Using above structure, after shell powers on positive and negative polarities with conductive rod, electrostatic field, electrostatic are formed between the two Field intensity is radially outward gradually reduced along conductive rod, is formed along the outside gradient electric field of conductive rod, and because being set on conductive rod There are the conductive bumps to extend radially outwardly along conductive rod, can be very good to weaken the attenuation degree of electric field diametrically, can Enough keep the higher gradient electric field of intensity, it is sufficient to the charged impurity in fluid-absorbent, while the gradient electricity for passing through Radial Rotation Error Field absorption neutral impurity, substantially increases dust removal rate, and need not apply high voltage to conductive rod and shell to obtain height Gradient electric field, avoids the infringement to fluid, causes fluid to go bad;
Simultaneously as using bulge-structure, inner space will not be greatly decreased, on removal of impurities flow without influence;The lower end of shell Import is set, and upper end sets outlet, and fluid flows from the bottom up, can avoid the impurity in fluid to a certain degree in housing bottom Deposition, for fluid in up motion process, impurity is affected by gravity, can preferably be attracted to the table of counter electrode Face, raising remove impurity level.

As preferred:The conductive rod is distributed in the shell in circle ring array.Using above structure, make in shell one Portion forms the non-homogeneous electrostatic field intersected along its axis, and the fluid impurity for flowing through same section is subject to conductive stud on multiple conductive rods The electric field action power of different directions is played, impurity-eliminating effect can be further improved.
It is connected for convenience of conductive rod with power supply, the conductive rod upper end is pierced by the shell.
As preferred:The conductive bumps are cylindrical, or are spherical.Using above structure, effectively reduce The distance between conductive bumps and shell, cooperatively form with shell and stablize higher non-homogeneous gradient electrostatic field, improve removal of impurities effect Rate.
As preferred:The diameter of the conductive bumps is less than or equal to 3mmm.Using above structure, conductive bumps are reduced Diameter, it is more thin better, contribute to the intensity of the non-homogeneous electrostatic field of enhancing generation, improve electrostatic removing impurities dynamics.
As preferred:The conductive bumps are taper, its section radius is radially outward gradually reduced along conductive rod. Using above structure, conductive bumps distal end is pointed, and approximation produces point charge effect, further improves non-homogeneous gradient electrostatic field Intensity, help to improve electrostatic removing impurities effect.
As preferred:The shell and conductive rod are made of an electrically conducting material.It using above scheme, can lead respective structure Electric is not in uniformly conductive harmful effect electric field stability, and then reduces impurity-eliminating effect.
Compared with prior art, the beneficial effects of the invention are as follows:
Non-homogeneous electrostatic field efficient impurity removal equipment provided by the invention, by setting conductive rod in cylindrical case, is leading The conductive bumps of outwardly convex are uniformly arranged on torch, form electrostatic field heterogeneous inside the shell, while effectively alleviate electrostatic The outside attenuation degree in field, it is opposite to improve electrostatic field intensity, match somebody with somebody with shell and the fluid to flowing through carries out stablizing purification and impurity removal, improve Equipment produces the dust removal rate of non-homogeneous gradient electrostatic field, finally obtains the fluid of stable quality, simple in structure, service life It is longer, there is very big economic value.
