Abstract

In the first stage, pref. acid washing is provided by nozzles (3) oriented in the direction of flow, then the air passes through a dividing wall (4), pref. formed as a droplet separator, into the second stage; here further nozzles (5) provide counter-flow washing, after which the ascending gas passes through a droplet separator (6), then through a condensate separator (7) to leave the vessel. The acid liquid from the first stage is recycled by a pump (9) to the nozzles while the wash liquid accumulating at the bottom of the vessel is oxidised by air jets (10) blown into it. For the washing of crude gases, esp. those polluted with HCl, SO2, HF etc. The arrangement provides two separate washing stages all incorporated into a single vessel.

Description

Beschreibung und Erläuterung zur Patent- und Hilfsgebrauchs-Description and explanation of the patent and auxiliary usage

musteranmeldung 'Zweistufenwäscher vorzugsweise für die Waschung von Rohgas' Vielfach gibt es Rohgase, die mit HC1, SO2, HF usw. belastet sind.sample registration 'two-stage scrubber, preferably for washing Raw gas' There are often raw gases that are contaminated with HC1, SO2, HF, etc.

Aus Prozeßgründen wird vielfach gewünscht, daß diese Rohgase zweistufig gewaschen werden, z. B. in der ersten Stufe eine saure Waschung erfahren und in der zweiten Stufe eine alkalische Waschung.For process reasons it is often desired that these raw gases take place in two stages be washed, e.g. B. experience an acidic wash in the first stage and in the second stage is an alkaline wash.

Vielfach wird in einem Kreislaufverfahren in der ersten Waschstufe mit der sauer eingestellten Waschflüssigkeit gefahren und in der zweiten Waschstufe alkalisch, wobei gleichzeitig eine Oxidation bei der alkalischen Waschfahrung gewünscht wird, um als Endprodukt z. B. ein CaS03- oder CaSO4-Gemisch zu erhalten, indem man das Waschmedium mit Kalkmilch angereichert hat.In many cases, the first washing stage is carried out in a cycle process driven with the acidic washing liquid and in the second washing stage alkaline, at the same time oxidation being desired in the alkaline washing experience is used as an end product z. B. to obtain a CaS03 or CaSO4 mixture by has enriched the washing medium with milk of lime.

Um diese Aufgabenstellungen zu erzielen, werden vielfach Wäscher in Reihe geschaltet und mit einem nachträglich angesetzten Oxideur versehen.In order to achieve these tasks, washers are often used in Connected in series and provided with a subsequently added Oxideur.

Um der Aufgabenstellung gerecht zu werden, d. h. sauer zu fahren, alkalisch zu fahren und gleichzeitig zu oxidieren, damit alles in einer einzigen Baueinheit problemlos durchgeführt werden kann, wird erfindunqsgemäß vorgeschlagen, eine Vorrichtung entsprechend beiliegender Zeichnung zu nutzen.To do justice to the task, i. H. to drive angry, driving alkaline and oxidizing at the same time, so all in one Assembly can be carried out without problems, it is proposed according to the invention, to use a device according to the accompanying drawing.

In der beiliegenden Zeichnung ist dargestellt: mit 1 die Waschstufe 1 mit 2 die Waschstufe 2 mit 3 z. B. die Waschdüsenanordnung, die mit saurer Flüssigkeit beschickt wird, mit 4 Tropfenabscheider, die das Wasser der sauren Waschlfüssigkeit abscheiden und den sauer gewaschenen Gasstrom in die zweite Waschstufe überleiten lassen, um hier mittels Düsen (5), die z. B. mit alkalischen Waschflüssigkeiten beaufschlagt werden, gereinigt zu werden, und hinter den Waschdüsen (5) sind wiederum Tropfenabscheider (6) angesetzt, um das Wasser in den Oxidationsbehälter, der als integrierter Bestandteil des Zweistufenwäschers im System eingebaut ist, abfließen zu lassen und nach Bedarf Luft aufzugeben2 um gleichzeitig eine Oxidation zum CasO4-Gemisch im Wäscher zu erhalten, mit 5 Waschdüsen mit 6 Tropfenabscheider mit 7 ein Entnebleroaket oder Kondensatabscheidepaket mit Wasserrückführung in die Oxidationsvorrichtung mit 8 die saure Waschflüssigkeit mit 9 eine Pumpenanordnung, die die saure Waschflüssigkeit (8) im Kreislauf fährt, mit 10 Luftzuführung.The accompanying drawing shows: with 1 the washing stage 1 with 2 the washing stage 2 with 3 z. B. the washing nozzle assembly, which with acidic liquid is charged, with 4 droplet separators, which remove the water from the acidic washing liquid and pass the acid-washed gas stream into the second washing stage let to here by means of nozzles (5), the z. B. with alkaline washing liquids are charged to be cleaned, and behind the washing nozzles (5) are in turn Droplet separator (6) attached to the water in the oxidation tank, which is used as a an integral part of the two-stage scrubber is built into the system to let go and after Need to give up air2 at the same time Obtain oxidation to the CasO4 mixture in the scrubber, with 5 washing nozzles with 6 droplet separators with 7 a defogger package or condensate separator package with water return to the Oxidation device with 8 the acidic washing liquid with 9 a pump arrangement, which circulates the acidic washing liquid (8), with 10 air supply.

Durch die obig beschriebene und in der Skizze dargestellte Anordnung ist mit geringstem Aufwand eine zweistufige saure und alkalische Waschung garantiert, wobei die Waschflüssigkeitsvorlage gleichzeitig noch als Oxidationsstufe ausgebildet ist.By the arrangement described above and shown in the sketch a two-stage acidic and alkaline wash is guaranteed with minimal effort, wherein the washing liquid reservoir is also designed as an oxidation stage at the same time is.
