Abstract

Air purification and conditioning involves ionizing pollutant particles using a spray electrode (3) and depositing the particles on a deposition electrode (4). The particles between the electrodes are brought in contact with surfaces having denaturing or oligodynamic effect. Ozone is introduced into the air to be cleaned in a region of the spray electrode. Excess ozone is removed from the cleaned air after the deposition electrode in the direction of flow. Independent claims are also included for the following: (A) a device for executing the purification and conditioning of air; and (B) an application of a device for executing the purification and conditioning of air, in an automobile field.

Description

Es ist bekannt, Gewebefilter zur Reinigung von verschmutzter Atemluft einzusetzen Diese Gewebefilter mit dem höchsten Luftreinigungseffekt werden als Absolutfilter bezeichnet. Sie dienen vorzugsweise in Krankenhäusern, insbesondere in OP- Räumen zur „so genannten absoluten Reinigung" von durch Klimaanlagen hergestellter, temperierter Luft für den OP- Tisch und somit für den zu operierenden sowie dem die Operation durchführenden Personal.It is known, fabric filter for cleaning polluted air These fabric filters will be with the highest air purification effect referred to as absolute filter. They are preferably used in hospitals, in particular in operating theaters to the "so absolute cleaning "of tempered air produced by air conditioning systems for the surgical Table and therefore for the one to operate and the one performing the operation Staff.

Diese Filter reinigen die Luft von allen festen Bestandteilen > 5μm jedoch werden die zu reinigenden Filterflächen mit Schadstoffen belastet z.B. mit Bakterien, Viren, Pilzen, Sporen und weiteren infektionserzeugenden Verunreinigungen. Feinste Insekten lagern sich ebenfalls auf den Gewebefiltern ab und bilden Endotoxine (= Leichengift). Das dabei entstehende Gas wandert durch den Gewebefilter und erzeugt Infektionen. Ein weiterer Nachteil solcher Gewebefilter mit der höchsten Abscheiderate ist der hohe Druckverlust und somit der sehr hohe Energiebedarf.These Filters clean the air of all solid components> 5μm, however, are the ones to be cleaned filter surfaces contaminated with pollutants e.g. with bacteria, viruses, fungi, spores and other infectious contaminants. Store the finest insects also precipitate on the tissue filters and form endotoxins (= Corpse poison). The resulting gas migrates through the fabric filter and produces infections. Another disadvantage of such fabric filters with the highest Separation rate is the high pressure drop and thus the very high Energy demand.

Um den Nachteil der bereits bekannten Gewebefilter zu vermeiden, wird erfindungsgemäß vorgeschlagen, nicht einen Gewebefilter zu verwenden, sondern einen Elektrofilter der besondere erfindungsgemäße Konstruktionsmerkmale aufweist. Elektrofilter, die Staub abscheiden, gehören zum Stand der Technik. Elektrofilter, die Viren und Bakterien abscheiden, müssen erfindungsgemäße Merkmale aufweisen, die in der Lage sind, dafür Sorge zu tragen, dass

  • a) eine ausreichende Menge Ozon erzeugt wird,
  • b) eine hohe Ionendichte erzeugt wird,
so dass in der Elektofilterstufe alle uns bekannten Mikroorganismen, wie Viren, Bakterien, Keime, gasförmige Schadstoffe und Gerüche durch Ozon oxidiert werden.In order to avoid the disadvantage of the already known fabric filters, the invention proposes not to use a fabric filter, but has an electrostatic precipitator of particular design features according to the invention. Electrostatic precipitators are state of the art. Electrostatic precipitators that secrete viruses and bacteria must have features according to the invention that are capable of ensuring that
  • a) a sufficient amount of ozone is generated,
  • b) a high ion density is generated,
so that in the Elektofilterstufe all microorganisms known to us, such as viruses, bacteria, germs, gaseous pollutants and odors are oxidized by ozone.

Auf oligodynamisch wirkenden Niederschlagselektroden werden die unerwünschten Luftverunreiniger agglomeriert angelagert und somit denaturiert. Erfindungsgemäß wird dann am Austritt des Elektrofilters ein faltenförmiger, ozonabscheidender Gewebefilter eingesetzt, der noch vorhandenes Ozon an dieser letzten Filteranordnung aus der bereits gereinigten Luft abscheidet, so dass eine „gesunde Luft" aus dem erfindungsgemäßen Luftreinigungsgerät austritt. In der beiliegenden Zeichnung ist der erfindungsgemäße Elektrofilter dargestellt.On oligodynamically acting precipitation electrodes are the undesirable Air contaminants agglomerated and thus denatured. According to the invention then at the outlet of the electrostatic precipitator, a fold-shaped, ozone-separating fabric filter used, the remaining ozone at this last filter assembly from the already purified air separates, leaving a "healthy Air "exits the air cleaning device according to the invention. In the accompanying drawing is the electrostatic precipitator according to the invention shown.

Die belastete Luft (1) tritt in das Elektrofiltergehäuse ein, wobei die ionenerzeugenden Spitzen (3) über einen oder mehrere Hochspannungsgeneratoren (2/2a) betrieben werden. Gleichzeitig wird auch Ozon erzeugt. Der Ozonwert wird über die erfindungsgemäße, selbstregulierende, vorgegebene Spannung zwischen 8 KV–12 KV je nach Luftfeuchtigkeit festgelegt. Die Schadstoffe werden durch das Ozon oxidiert und Viren, Bakterien, Pilze und weitere Mikroorganismen werden gleichzeitig mit den staubförmigen Körpern abgetötet, agglomeriert und auf der oligodynamisch wirkenden Niederschlagselektrode (4) angelagert und denaturiert.The polluted air ( 1 ) enters the electrostatic filter housing, with the ion-generating tips ( 3 ) via one or more high voltage generators ( 2 / 2a ) operate. At the same time ozone is generated. The ozone value is determined by the inventive, self-regulating, predetermined voltage between 8 KV-12 KV depending on the humidity. The pollutants are oxidized by the ozone and viruses, bacteria, fungi and other microorganisms are killed simultaneously with the dust-like bodies, agglomerated and on the oligodynamically acting precipitation electrode ( 4 ) and denatured.

Hierdurch sind alle Schadstoffe aus der verschmutzten Luft (1) getötet und abgeschieden. Schlussendlich wird überschüssiges Ozon über ein Spezialfilter (5) abgeschieden, so dass eine gesunde, nicht mehr mit Schadstoffen belastete Luft (6) am Ende des Gerätes austritt. Selbstverständlich ist die Erfindung nicht nur auf die vorstehend beschriebene und dargestellte Ausbildungsform beschränkt, sondern es sind Systemabänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, dass die Wirkung der Luftreinigung auf der in der Wirkung der Konstruktion beispielhaft der dargestellten Systemtechnik beruht, wonach organische Substanzen oxidiert, mit Stäuben agglomeriert und auf den oligodynamisch wirksamen Niederschlagsflächen abgeschieden und denaturiert werden.As a result, all pollutants from the polluted air ( 1 ) killed and separated. Finally, excess ozone is released via a special filter ( 5 ) so that a healthy, no longer polluted air ( 6 ) at the end of the device. Of course, the invention is not limited to the above-described and illustrated embodiment, but system modifications are possible without departing from the spirit that the effect of air cleaning is based on the system technology exemplified in the effect of the construction, which oxidizes organic substances , agglomerated with dusts and deposited on the oligodynamically effective precipitation surfaces and denatured.
