Abstract

It is known to quench coke in quenching towers, but the emission and the discharge of steam creates a nuisance (pollution). It has therefore already been proposed to use coke dry cooling in which the dust nuisance can be reduced to virtually zero by an encasing and filter technique. Nevertheless, even in this method severe SO2 emission occurs, as well as release of lean gas as leakage from the lock systems. In order to overcome these disadvantages and avoid the expense associated with coke dry cooling, the invention proposes to provide, above the coke quenching car (2), a quenching hood (1) with the emission collected by the latter being led via a steam cooling hood (4) to a cooling zone (5), preferably constructed as a condenser, from which the condensate liquid is drawn off at (6), with the residual air being passed through a deduster (dust precipitator) (7). The cooling zone (5) is sprayed with SO2-scrubbing liquids. The waste water is fed to a water treatment installation, e.g. a sewage plant and/or biological installation and/or a small concentrator unit. <IMAGE>

Description

Es ist bekannt, Koks über Löschtürme zu löschen. Löschtürme mit Tropfenabscheidern und nasse Abscheider im Löschturm sind ebenfalls bekannt.It is known to extinguish coke via fire towers. Extinguishing towers with droplet separators and wet separators in the extinguishing tower are also known.

Doch die Emissson und der Dampfaustritt wirken belästigend.But the emissson and the steam outlet work annoying.

In neuerer Zeit werden vielfach Kokstrockenkühlungen angewandt. Hierbei ist über Einhausung- und Filtertechnik die Staubbelastung auf nahezu 0 herabzudrücken.In recent times, coke dry cooling has become common applied. Here is about housing and filter technology to reduce the dust pollution to almost 0.

Andererseits werden
1. starke SO2-Emission und
2. Schwachgas als Verlust der Schleusen, sogenanntes Koksgas, freigesetzt.
On the other hand
1. strong SO 2 emissions and
2. Low gas is released as a loss of the locks, so-called coke gas.

Hinzukommt, daß die Kokstrockenkühlung einen erheblichen finanziellen Aufwand darstellt. Für mittelgroße Kokereien sind Anlagen mit einem Kostenaufwand von mehr als 100 Mio DM zu installieren, um mit genügend hoher Verfügbarkeit die Kokstrockenkühlung zu ermöglichen.In addition, the dry coke cooling is considerable represents financial expense. For medium-sized coking plants are systems with a cost of more than 100 million DM to install with enough high Availability to enable coke dry cooling.

Die Wärmerückgewinnung ist in der Regel kaum oder nicht nutzbar.The heat recovery is usually little or no usable.

Im Gegensatz dazu wird erfindungsgemäß vorgeschlagen, eine fast vollkommen emissionsfreie Naßlöschung einzusetzen, die entsprechend folgendem Verfahren ausgebildet ist.In contrast, the invention proposes use an almost completely emission-free wet extinguishing system, who are trained according to the following procedure is.

In der beiliegenden Zeichnung ist das Verfahren dargestellt:
mit (1) eine Löschhaube;
mit (2) der Kokslöschwagen;
mit (3) das Löschwasser;
mit (4) die Dampfkühlhaube;
mit (5) die Kühlstrecke, vorzugsweise als Kondensator ausgebildet,
mit (6) das Ableiten der Kondensatflüssigkeit und der abgekühlten Restluftmengen;
mit (7) ein Entstauber, z. B. Naßelektrofilter mit z. B. kleiner 1 mg Reststaubgehalt.
The process is shown in the accompanying drawing:
with ( 1 ) an extinguishing hood;
with ( 2 ) the coke fire truck;
with ( 3 ) the fire water;
with ( 4 ) the steam cooling hood;
with ( 5 ) the cooling section, preferably designed as a condenser,
with ( 6 ) the discharge of the condensate liquid and the cooled residual air quantities;
with ( 7 ) a deduster, e.g. B. wet electrostatic precipitator with z. B. less than 1 mg residual dust content.

Bedenkt man dabei, daß die Spitzenbelastung bei etwa 25 000 m3 dampfförmiger Emission/Min. beträgt und die Löschvorgänge etwa 2 Minuten dauern, so ist die Spitzenbelastung etwa 50 000 m3 für die zwei Minuten Emission.If you consider that the peak load at about 25 000 m 3 vapor emission / min. is and the extinguishing processes take about 2 minutes, the peak load is about 50,000 m 3 for the two minute emission.

Durch die Kondensatoranordnung kann diese Spitzenleistung auf einen Bruchteil heruntergedrückt werden z. B. auf weniger als 2000 m3/Min.This peak power can be reduced to a fraction by the capacitor arrangement, e.g. B. to less than 2000 m 3 / min.

Hier kann aufgrund der geringen Abluftmengen ein Hochleistungsfiltersystem Anwendung finden, das die Emissionen auf nahezu 0 mg herunterdrückt.Here, due to the small amount of exhaust air Find high performance filter system that the Emissions down to almost 0 mg.

Im Bereich des Kondensators wird erfindungsgemäß alkalische Waschflüssigkeit verwendet, die
1. die Restemissionen auswäscht
und
2. die Kondensationseinbauten freispült.
In the area of the condenser, alkaline washing liquid is used according to the invention
1. Washes out the remaining emissions
and
2. Flush the condensation internals.

Das Abwasser wird einer Wasseraufbereitungsanlage, z. B. Kläranlage und/oder Biologie und/oder auch Kleineindampfanlage zugeführt, um dadurch die Aussalzung des Wassers zu vermeiden.The wastewater is sent to a water treatment plant, e.g. B. wastewater treatment plant and / or biology and / or Small evaporation system fed to thereby the Avoid salting out the water.

Diese beschriebene erfindungsgemäße Vorrichtung zur Durchführung eines Verfahrens kostet nur einen Bruchteil einer Kokstrockenkühlung und bewirkt umwelttechnisch zumindest die gleichen Vorteile.This described inventive device for Carrying out a procedure costs only a fraction a coke dry cooling and environmental effects at least the same benefits.
