Abstract

The invention relates to a process for flue gas desulphurisation, preferably downstream of old power stations having low cooling towers. According to the main application P 3314678.0, the scrubbed flue gas from the flue gas desulphurisation plant is passed via a large surface area distributor into the vicinity of the bottom of the cooling tower. In order to achieve design distribution in the vicinity of the bottom to be on as large a surface area as possible, according to the invention it is proposed to design the gas feed (1) in the shape of a ring, that is to arrange it open towards the water flume (9) and to immerse and support this in the water flume so that the trickling water from the cooling tower (3) flows through the ring arrangement downward into the water flume and in the course of this at the same time washes out the entrained droplets from the scrubbed dirty gas. The boundary surfaces of the distributor (4) are perforated. <IMAGE>

Patentanmeldung "Verfahren zur Rauchgasentschwefelung mit Gasverteiler im Kiihlturm ohne Bodenfläche" Zusatzpatentanmeldung zu P 33 14 678.0 In der Hauptanmeldung P 33 14 e 8.O wird ein Verfahren zur Rauchgasentschweßeiung vorzugsweise hinter Altkraftwerken mit niedrigem Kühlturm beschrieben, wobei das gewaschene Rauchgas aus der Rauchgasentschwefelungsanlage über einen großflächigen Verteiler in Bodennähe des Kühlturms eingeleitete wird.Patent application "Process for flue gas desulphurization with gas distributor in the cooling tower without floor space "additional patent application to P 33 14 678.0 in the main application P 33 14 e 8.O a process for flue gas removal is preferred Old power plants with low cooling towers described, with the scrubbed flue gas from the flue gas desulphurisation system via a large-area distributor close to the ground of the cooling tower is initiated.

Um die Verteilung in Bodennähe größtflächig auszubilden, wird erfindungsgemäß vo-rgeschlagen, die Gaseinleitung ringförmig vorzunehmen -wie in der beiliegenden Zeichnung mit (1) dargestellt - und ohne Boden auszubilden und tunlichst in der Wassertasse anzutauchen und abzustützen, so da1d das Rieselwasser aus dem Kühlturm durch die Ringanordnung nach unten in die Wassertasse abfließt und dabei gleichzeitig erfindungsgemäß den Tropfendurchriß aus dem gewaschenen Rohgas auswäscht - wie in der beiliegenden Zeichnung dargestellt.In order to develop the distribution over a large area near the ground, according to the invention suggested, to introduce the gas in a ring -as in the accompanying drawing with (1) - and train without a bottom and to submerge and support it in the water cup if possible, so that the trickling water flows down from the cooling tower through the ring arrangement into the water cup and at the same time, according to the invention, the teardrop opening from the scrubbed raw gas washes out - as shown in the accompanying drawing.

Es ist vorteilhaft, die Verteiler-Begrenzungsflächen zu perforieren, um eine bestmögliche Flächenverteilung des eingeleiteten Gases zu erzielen.It is advantageous to perforate the distributor boundary surfaces, in order to achieve the best possible area distribution of the gas introduced.

In der beiliegenden Zeichnung ist dargestelt: mit (1) die Gaseinleitung mit (2) der Gasaustritt aus dem Diffusorbereich mit (3) der Kühlturm mit (4) die diffusorartige Darstellung -rund oder eckig mit (5) die Tropfenabscheider mit (6) z.B. die Rieseldüsen mit (7) das Rieselwasser mit (8) das ankommende, gewaschene Rohgas mit (9) das sich auf dem Kühlturm-Boden ansammelnde Kühlwasser mit (10) der Ablauf des Kühlwassers.The accompanying drawing shows: with (1) the gas inlet with (2) the gas outlet from the diffuser area with (3) the cooling tower with (4) the diffuser-like Representation - round or square with (5) the droplet separators with (6) e.g. the trickle nozzles with (7) the trickling water with (8) the incoming, washed raw gas with (9) the itself Cooling water accumulating on the cooling tower floor with (10) the drainage of the cooling water.

Erfindungsgemäß wird hiermit weiter erreicht, daß noch eine zusätzliche Nachwaschung der bereits gereinigten Gase, die aber immerhin noch einen Rest an Schwefeldioxid enthalten, in der Berieselungszone des Kühlturms zwangsläufig erfolgt.According to the invention it is hereby further achieved that an additional Post-washing of the already cleaned gases, but they still show a residue Containing sulfur dioxide, inevitably occurs in the irrigation zone of the cooling tower.

Durch diese Anordnung ist die Gewähr gegeben, daß geringstmöglicher S02-haltiger Nebelauswurf aus dem Kühlturm erreicht wird.This arrangement ensures that the least possible S02-containing fog is achieved from the cooling tower.
