Description

Filter techniques for gaseous, liquid and solid substances are from the building, Vehicle, drinking water and construction technology e.g. in the form of air filters, desalination plants and seven relevant known.

For seawater desalination plants are e.g. Filters known in which the filter material or Filter cartridges cleaned and reused in an external process can be.

These techniques have in common that with them the filter material has to be changed relatively frequently.

The special advantage of the SRF is in that the filter material is contrary to known techniques can be used for a relatively long time without maintenance and thus the operating costs can be reduced by a lower material requirement and thereby in relation to works very environmentally friendly.

It can be used in all areas be where a desired Substance from undesirable substances should be separated e.g. as in the application example below for one Building ventilation.

Through a primary propeller ( 2 ) air is sucked in and through filter material ( 8th ) cleaned. The relatively large area on the outside air intake side results in a relatively low flow velocity, which keeps the depth of penetration of the particles to be filtered out into the filter material small.

When using the SRF in places where the cleaned air is contaminated according to the usage, in this example for building ventilation, the primary propeller draws in more air than is required for building ventilation. The excess amount of the sucked-in and cleaned air that goes beyond the amount required for building ventilation is reduced by a secondary propeller ( 3 ) derived and blown out through the filter material over a relatively small area. Due to the relatively small area in relation to the outside air intake side, a relatively high flow velocity is created, which means that the particles that have settled on the filter material from the outside or have been stored in it, by subdivision into the intake and exhaust area or air cleaning and filter cleaning area and rotation ( 4 ) of the filter material carrier ( 5 ) around these two points.

The cleaned air in the filter cleaning area will before blowing out for keeping the filter material dry e.g. through a heating wire heated.

To avoid investing from Pathogens or foci of infection is in the filter cleaning area a disinfectant atomizer e.g. installed in the form of a sprinkler system, which at night, then if in the building least operation is turned on. During the disinfection cycle is the building ventilation through a flow channel plug regulator or flow regulator interrupted.

There is a flow channel at the SRF ( 19 ) attached, which adapts and the SRF to the wind direction. Due to the flow pressure of the wind and wings ( 9 ) which are provided with a mechanism that places the blades in the wind, suction and blow-out flow, the filter material carrying body ( 15 ) made to rotate. With these additional devices, which are not absolutely necessary for the primary function of the SRF, the primary propeller and filter body rotation motor ( 1 . 7 ) and the secondary propeller are relieved by the resulting vacuum on the side facing away from the wind, energy can possibly be generated by recuperation.

The SRF can be both radial and axially rotating (filter material carrier around carrier body of the filter material carrier or Carrier body of the Filter material carrier along the filter material carrier or carrier body of the Filter material carrier against filter material carrier or carrier body of the Filter material carrier with filter material carrier operated with speed difference).

The SRF would look particularly in the vehicle sector prove to be economical because here, based on the number of pieces, the largest application market is.

It is advantageous for this Retrofit kit for existing Offer vehicles and filter types.

For devices and systems, for which some airflow for the cooling or warming needed and the air through the devices and systems are not or only slightly contaminated and the devices or Attachments about its own fan dispose of how z. B. in computers or motors such. B. the AEA, can be on the primary and secondary propellers, the heating and disinfection devices and possibly also on the filter carrier rotation motor through a mechanical connection between rotating or moving Part of the device or the system and filter carrier to be dispensed with. Here, the cleaned air through the device or the System and then used for filter material cleaning.

The air for filter cleaning can also be connected directly to the fresh air area and filter cleaning area by appropriate flow restrictions ( 17 ) can be drawn in by dividing the filter area, e.g. 1/10 filter cleaning area, 4/10 fresh air intake for filter cleaning and 5/10 fresh air intake for building ventilation. This separates the two primary functions of building ventilation and filter cleaning.

The SRF flow channels can also be equipped with heat exchangers, through which the amount of fresh air supplied is used or the resulting pressure in the building or the like. by supplying fresh air is pressed and the heating costs are reduced by exchanging the thermal energy.

Claims (18)

Self-cleaning filter (SRF), characterized in that an individual filter material with at least one individual mechanical unit and individual supply and exhaust air devices is connected so individually that the filter and, or the supply and exhaust air ducts move in such a way (usually through some form of rotational movement) that air or other forms of matter are cleaned or separated on one side of the filter and that the cleaned medium exits through the filter at least at another point due to the movement of the filter and / or the supply and exhaust air channels, Particles that have settled in the filter due to the medium being sucked in are blown out completely or partially.
