Abstract

To seal the door of a horizontal coke oven chamber against its frame, a fluid sealing compound is introduced into the peripheral cavity left between steel sections of the surrounding structure. When the door has been opened at the end of each coking cycle, the solidified cpd. is removed by mechanical means and renewed after the door has been closed. Specifically the sealing cpd. is an aq. paste of loam or clay which is made up with ammoniacal water. Pref. the loam or clay is predried and the ammoniacal water then added to it, espec. in an amt. 5-40 wt.% (based on the dry wt.).

Description

Verfahren und Vorrichtung zur Abdichtung Method and device for sealing

von Koksofentüren (Zusatz zu Patentanmeldung P 25 48 714.3) Die Hauptanmeldung betrifft neben einer Vorrichtung ein Verfahren zur Abdichtung von Koksofentüren mit den Flanken des Türkörpers selbst und bzw. oder mit justierbaren Einfassungen, wie Flacheisen oder Z-Eisen, den Schenkeln von U-Eisen und anderen Profileisen, die in TUrschlußstellung an den Türrahmen angelegt werden, und es ist dadurch gekennzeichnet, dass in dem durch die Flanken des TUrkörpers,ein einfassendes Flacheisen oder Z-Eisen und den Türrahmen bzw. durch die Schenkel von U- oder Z-Eisen und anderen Profileisen und den TUrrahmen gebildeten Ringkanal um die Ofenkammertür herum zur Abdichtung nach dem FUllvorgang der Ofenkammer eine fliessfähige Dichtmasse eingebracht wird und nach jedem Öffnen der Ofenkammer am Ende des Verkokungsevorqanges die während der Verkokung erha-'Pte Dchtmasse mechanisch entfernt wird. Aus dem Koks sind diese Massen dann leicht abtrennbar, oder sie sind brennbar und eine Abtrennung solcher geringer Mengen von fremder Substanz ist nicht notwendig. of coke oven doors (addition to patent application P 25 48 714.3) The main application relates to a device and a method for sealing coke oven doors with the flanks of the door body itself and / or with adjustable bezels, such as flat iron or Z-iron, the legs of U-iron and other profile iron, which are placed on the door frame in the closed position, and it is characterized by that in that through the flanks of the body, a surrounding flat iron or Z-iron and the door frame or through the legs of U or Z irons and other profile irons and the ring channel formed by the door frame around the furnace chamber door for sealing after the furnace chamber has been filled, a flowable sealing compound is introduced and after each opening of the oven chamber at the end of the coking process the during the dense mass obtained after coking is removed mechanically. These are from the coke Masses can then be easily separated, or they are flammable and a separation of such small amounts of foreign substance is not necessary.

Als fliessfähige Dichtmassen haben sich unter anderem wässerige AnrUhrungen von Lehm oder Ton als geeignet erwiesen, und es ist auch zweckmässig, den fliessfähigen Anrührungen oder Pasten Bldhmittel, z. a. Ammonkarbonat bzw. Ammonbikarbonat, zuzusetzen.Water-based compounds have proven themselves as flowable sealing compounds of loam or clay proved to be suitable, and it is also expedient to use the flowable Mixtures or pastes fertilizers, e.g. a. Add ammonium carbonate or ammonium bicarbonate.

£s wurde nun gefunden, dass man als besonders billiges und wirksames Blähmittel den AnrUhrungen Ammoniakwasser, das bei der Aufarbeitung des Kokereigases anfällt, zusetzen kann.£ s has now been found to be particularly cheap and effective Blowing agent to the mixings ammonia water, which is used in the processing of the coke oven gas accrues, can clog.

Frisch gestochener Lehm hat ohne Vorbehandlung und Vortrocknung einen Wassergehalt von etwa 2o bis 30 Prozent.Freshly cut clay has one without pretreatment and pre-drying Water content of about 20 to 30 percent.

Aus diesem Lehm kann man eine fliesafähige AnrUhrung oder Paste erhalten, wenn man ihm 5 bis 20 Prozent seines Gewichtes an Xokereiammoniakwasser zusetzt. Das Ammoniakwasser enthält etwa o,5 bis 5 Prozent Ammonkarbonate, die.ausreichen, um der AnrUhrung die erwünschte geringe Blähfähigkeit zu verleihen.A mixture or paste that can be flowed can be obtained from this clay, if you add 5 to 20 percent of its weight in xokerei ammonia water to it. The ammonia water contains about 0.5 to 5 percent ammonium carbonates, which are sufficient in order to give the mixture the desired low expandability.

Es ist jedoch auch möglich, den Lehm z.B. bei etwa 200°C und mit Abwärme der Kokerei vorzutrocknen. Man kann dann, je nach dem Grad der Vortrocknung, bis zu 40 Prozent des Trockengewichtes des tehms oder Tons an Ammoniakwasser zusetzen und erhält dann eine entsprechende blähfähige AnrUhrung.However, it is also possible to use the clay e.g. at around 200 ° C and with waste heat to pre-dry the coking plant. You can then, depending on the degree of pre-drying, up to Add ammonia water to 40 percent of the dry weight of the clay or clay and then receives a corresponding expandable mixture.

Schliesslich ist es auch im Bedarfsfall möglich, den Ammonkarbonatgehalt des Ammoniakwassers durch ZufUgen und Lösen von zusätzlichem Ammonkarbonat oder Bikarbonat darin zu erhöhen.Finally, if necessary, it is also possible to check the ammonium carbonate content the ammonia water by adding and dissolving additional ammonium carbonate or Increase bicarbonate in it.
