- each package of collecting electrodes is designed to generate an inhomogeneous electric field when exposed to flux voltage.
- adjacent packages are separated from one another by means of an elongated dielectric partition. It is preferred that the collecting electrodes are divided into at least three packets, the length of the partition walls between adjacent packets increasing, decreasing or being identical in the direction of flow of the fluid.
- the number of collecting electrodes in each packet increases, decreases or remains the same in the direction of flow of the fluid.
- the length of the packets of collecting electrodes increases, decreases or remains the same in the direction of flow of the fluid.
- the length, d2, of the further elongated dielectric partition wall is greater than the length, d1, of the elongated dielectric partition wall, the value of the length, d1 or d2, of the elongated dielectric partition walls being equal to or greater than the length, c1 or c2, of the package of collecting electrodes, which is located upstream in front of the respective partition.
- the length of the next packet of collecting electrodes is greater than the length of the previous packet of collecting electrodes.
- the length, d2, of the further elongated dielectric partition wall is smaller than the length, d1, of the elongated dielectric partition wall, the length, d1 or d2, of the elongated dielectric partition walls being equal to or greater than the length, c1 or c2, of the package of collecting electrodes, which is located upstream in front of the respective partition.
- the length of the next bundle of collecting electrodes is less than that of the previous bundle of collecting electrodes.
- the housing has high-voltage bushings for connecting adaptive high-voltage supply devices.
- each collecting electrode has at least one longitudinal channel for the passage of the fluid.
- adjacent collecting electrodes of the same package define a memory cell between them.
- each longitudinal channel fluidly connects a pair of adjacent storage cells.
- the housing has an inlet and an outlet for the fluid at its respective end regions.
- the housing contains, adjacent to its respective end regions, in each case a fluid-permeable, preferably air-permeable, delimitation plate, which spacing the collecting electrodes from the wall of the housing and electrically isolating them.
- the invention provides a filter device comprising a preferred electrostatic precipitator and an adaptive high voltage source for supplying different electrical high voltage direct current for supplying the packets of collecting electrodes with different potentials.
- the invention creates a use of an electric filter for cleaning dielectric fluids, in which several spaced apart and electrically separated packets of collecting electrodes can each be acted upon and / or calibrated with different electrical potentials in such a way that the strength of the electrical field in the flow direction of the fluid, preferably the air, changed.
- the strength of the electric field increases or decreases in the direction of flow of the fluid, preferably the air.
- the fluid preferably the air
- the fluid is filtered in stages in the direction of flow.
- the invention creates a cleaning method for cleaning dielectric fluids, preferably air, by means of an electrostatic precipitator, the electrostatic precipitator having a housing containing a plurality of collecting electrodes, the collecting electrodes forming at least two electrically separated packages and the fluid flowing through the packages.
- Each package of collecting electrodes is preferably subjected to high voltage and an inhomogeneous electrical field is generated.
- the electrostatic precipitator preferably filters the fluid in stages.
- the electrostatic precipitator can be a previously described preferred electrostatic precipitator.
- a fluid is, for example, a mixture of a fluid and solid particles.
- the fluid can be gaseous or liquid.
- the fluid itself can also be a mixture, for example a mixture of several immiscible liquids, i.e. an emulsion.
- the fluid mixture is, for example, a heterogeneous mixture such as an aerosol, a suspension or a mixture of an emulsion and solid particles.
- the fluid is air.
- Electrostatic precipitators or also called electrostatic precipitators, which are based on the electrostatic principle, are known for cleaning the fluids from impurities.
- One idea is to divide the hitherto only pack of collecting electrodes into several packs of collecting electrodes, for example by inserting elongated dielectric separating walls between the packs.
- different values of the potential difference of adaptive high-voltage power supply units can be supplied for each package of collecting electrodes.
- the pins previously used, which fulfill the wiring function, can be replaced by high-voltage bushings.
- the result is a structure of independent packages, each optimized for cleaning particles of the required size.
