Description

Verfahren zur Vorbehandlung von staub- und rauchhaltigen Gasen für die Reinigung. Es ist schon vorgeschlagen worden,- Staubgas vor der elektrischen oder mechanischen Reinigung einer elektrischen Vorbehandlung zu unterwerfen, die die Fremdteilchen zu größeren Gebilden zusammenballt. Zu diesem Zwecke hat man elektrische Entladungen durch das Gas geschickt, die an sich nich: stark genug zur Abscheidung des Staubes waren, sondern nur die Zusammenballung der Staubteilchen bewirken sollten.Process for the pretreatment of gases containing dust and smoke for the cleaning. It has already been suggested - dust gas before electric or to subject mechanical cleaning to electrical pretreatment, the the foreign particles agglomerate to form larger structures. For this purpose one has electrical ones Discharges sent through the gas, which in themselves are not: strong enough for separation of the dust, but should only bring about the agglomeration of the dust particles.

Beobachtungen haben ergeben, daß man die flockenbildende Wirkung schwacher elektrischer Entladungen beträchtlich vermehren kann, wenn man diese Entladungen zwischen dauernd oder sehr schnell sich abreinigenden Elektroden vor sich gehen läßt. Die auf den Elektroden niedergeschlagene Substanz wird durch die Abreinigung dauernd abgerissen und im Gasstrom in Form von elektrisch geladenen Flocken mitgeführt. Die abgerissenen Flocken vergrößern sich dabei durch Anziehung kleiner Teilchen und führen eine um so vollkommenere Agglomeration herbei, je länger Flocken und Rokigas .in Berührung bleiben. Die Vorteile des beschriebenen Verfahrens gegenüber der bisher angewandten elektrischen Flockung mit nicht oder nicht dauernd abgereinigten Elektroden bestehen in einem vergrößerten Wirkungsgrad der Flockung, da der Vorgang sich nicht im Feld der elektrischen Entladung abspielt. Außerdem Weib, die Vorbehandlung dauernd wirksam, da die Unterbrechung der elektrischen Entladung durch niedergeschlagenen Staub wegfällt.Observations have shown that the flake-forming effect is weaker electrical discharges can multiply considerably if you consider these discharges between electrodes that are constantly or very quickly cleaning themselves leaves. The substance deposited on the electrodes is removed by the cleaning process permanently torn off and carried along in the gas stream in the form of electrically charged flakes. The flakes that are torn off are enlarged by the attraction of small particles and bring about a more perfect agglomeration, the longer the flakes and Rokigas. Stay in touch. The advantages of the method described above the previously used electrical flocculation with not or not permanently cleaned Electrodes consist in increased flocculation efficiency as the process does not take place in the field of electrical discharge. Besides, woman, the pretreatment permanently effective because the electrical discharge is interrupted by being depressed Dust falls away.

PATENT-ANSPRUCH: Verfahren zur Vorbehandlung von staub-und rauchhaltigen Gasen für die elektrische und mechanische Reinigung, dadurch gekennzeichnet, daß im Rohgas durch eine elektrische Sprühentladung zwischen schnell durch mechanische Einrichtungen, nicht durch den Gasstrom selbst, sich abreinigenden Elektroden die Bildung elektrisch geladener Flocken bewirkt wird, die im Gasstrom mitgeführt werden und dabei die Zusammenballung vervollständigen.PATENT CLAIM: Process for the pretreatment of dust and smoke containing Gases for electrical and mechanical cleaning, characterized in that in the raw gas by an electrical spray discharge between quickly by mechanical Devices, not by the gas flow itself, cleaning electrodes Formation of electrically charged flakes is caused, which are entrained in the gas stream and thereby complete the agglomeration.
