Description
Die Erfindung betrifft eine Vorrichtung zur Probenahme für Gasanalysen von stark mit Verunreinigungen, insbesondere mit Feststoffen und Teer, befrachteten Gasen gemäß dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Gasanalyse dieser Gase.The invention relates to a device for sampling for gas analysis of strong with contaminated gases, especially with solids and tar according to the preamble of claim 1 and a method for gas analysis these gases.
Das bei der Verkokung von Steinkohle erzeugte Koksofenrohgas ist ein braungel bes Gemisch von Gasen und Dämpfen. Es besteht vornehmlich aus Wasserstoff, Methan, ungesättigten Kohlenwasserstoffen, Kohlenoxyd, Kohlendioxyd, Stickstoff, Ammoniak, Schwefel und Schwefelwasserstoff sowie Teer.The raw coke oven gas produced by coking coal is a brown gel mixture of gases and vapors. It’s mostly hydrogen, Methane, unsaturated hydrocarbons, carbon oxide, carbon dioxide, nitrogen, Ammonia, sulfur and hydrogen sulfide and tar.
Um das Koksofenrohgas als Heizgas in Stahlwerken oder Kraftwerken zu verwen den oder in ein Gasnetz einzuspeisen, ist seine Reinigung in einer speziellen Koksofenrohgasbehandlungsanlage erforderlich. Das von den Koksöfen kommen de Wasserdampf gesättigte, ca. 80°C heiße Koksofenrohgas wird zunächst indi rekt gekühlt und elektrostatisch entteert, bevor es von Schwefelwasserstoff, Am moniak, Benzol und Naphthalin weitgehend befreit wird. To use the raw coke oven gas as heating gas in steel plants or power plants Feeding in or into a gas network is its cleaning in a special Coke oven raw gas treatment plant required. That come from the coke ovens de Steam saturated coke oven raw gas at approx. 80 ° C is initially indi cooled and electrostatically de-iced before it was released by hydrogen sulfide, Am moniak, benzene and naphthalene is largely freed.
Aufgrund des hohen Anteils an partikelförmigen und teerigen Bestandteilen im Koksofenrohgas, ist es nicht möglich, das von den Koksöfen kommende, wasser dampfgesättigte ca. 80°C heiße Koksofenrohgas kontinuierlich zu beproben, um Gasanalysen im ON-LINE-Betrieb durchzuführen. Aus diesem Grunde findet die kontinuierliche Beprobung des Koksofenrohgases erst nach der indirekten Gas kühlung und der elektrostatischen Entteerung im kalten Bereich (ca. 20°C) statt. Der Wartungsaufwand bei dieser Probenahme ist allerdings auch dort noch sehr hoch. Eine kontinuierliche Sauerstoffmessung im Koksofenrohgas kann somit erst am Austritt des Elektrofilters erfolgen. Deshalb muß die Zeit für das Abschalten des Elektrofilters bei einem Feststellen eines explosionsfähigen Gemisches in die sem Bereich sehr kurz bemessen werden. Der Abschaltpunkt für das Elektrofilter wird üblicherweise auf einen Grenz-Sauerstoffgehalt von weniger als 2% im Koksofenrohgas gelegt. Das führt häufig zu unnötigen Stillständen im Bereich der Koksofenrohgasentteerung.Due to the high proportion of particulate and tarry components in the Raw coke oven gas, it is not possible to get the water coming from the coke ovens to continuously sample steam-saturated coke oven raw gas at approx. 80 ° C Perform gas analyzes in ON-LINE mode. For this reason, the continuous sampling of the raw coke oven gas only after the indirect gas cooling and electrostatic removal in the cold area (approx. 20 ° C). However, the maintenance effort for this sampling is still very high there high. A continuous oxygen measurement in the raw coke oven gas is only possible at the outlet of the electrostatic filter. Therefore the time to switch off of the electrostatic precipitator if an explosive mixture is found in the be very short. The cut-off point for the electrostatic filter is usually reduced to a limit oxygen content of less than 2% Coke oven raw gas laid. This often leads to unnecessary downtimes in the area of Coke oven raw gas depletion.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung und Verfahren zur Verfügung zu stellen, mit der eine kontinuierliche Probenahme und Analyse von stark mit Verunreinigungen, wie Feststoffen und Teer befrachteten Gasen mit ge ringem Wartungsaufwand zuverlässig möglich ist. Vorzugsweise soll die Reakti onszeit für die Abschaltung elektrostatischer Entteerungsanlagen für Koksofen rohgas verlängert werden. Eine weitere Aufgabe ist die Bereitstellung eines Ver fahrens zur Gasanalyse dieser Gase.The invention has for its object a device and method for To provide with the continuous sampling and analysis of Gases heavily contaminated with contaminants such as solids and tar low maintenance is reliably possible. The reaction should preferably onswitch-off of electrostatic dewatering systems for coke ovens raw gas can be extended. Another task is to provide a ver driving for gas analysis of these gases.
Diese Aufgabe wird im Hinblick auf die Vorrichtung durch die Merkmale des Pa tentanspruchs 1 und im Hinblick auf das Verfahren durch die Merkmale des Pa tentanspruchs 16 gelöst.This task is performed with regard to the device by the features of Pa claim 1 and with regard to the method by the features of Pa claim 16 solved.
Weiterbildungen erfolgen gemäß den Merkmalen der Unteransprüche.Further developments take place according to the characteristics of the subclaims.
Gemäß der Erfindung wird das zu analysierende Probegas in einer Probenahme leitung und in einem Elektrofilter auf der Temperatur gehalten, bei der die Probenahme erfolgt. In der Regel beträgt diese Temperatur bei Koksofenrohgas ca. 80°C. Die Probenahmeleitung und das Elektrofilter müssen weitgehend kondensa tionsgeschützt ausgeführt sein, z. B. durch Isolierung, damit Wasser und Teer nicht nennenswert auskondensieren können, was zu Anbackungen in der Probe nahmeleitung und dem Elektrofilter führen würde. Bevorzugt ist eine Beheizung der Probenahmeleitung und des Elektrofilters auf eine Temperatur die der Tempe ratur des Probegases bei der Probenahme entspricht.According to the invention, the sample gas to be analyzed is sampled line and kept in an electrostatic filter at the temperature at which the sampling he follows. As a rule, this temperature for coke oven raw gas is approx. 80 ° C. The sampling line and the electrostatic filter must largely be condensed tion-protected, z. B. by insulation so that water and tar cannot condense out appreciably, leading to caking in the sample would lead and the electrostatic filter. Heating is preferred the sampling line and the electrostatic precipitator to a temperature equal to the temperature corresponds to the temperature of the sample gas during sampling.
Durch Versuche mit Koksofenrohgas wurde festgestellt, daß das Elektrofilter bei einer Temperatur von ca. 80°C einen deutlich höheren Wirkungsgrad als bei nied rigeren Temperaturen aufweist. In dem beheizten Elektrofilter werden 99,99% der Feststoffe abgeschieden. Das Probegas wird anschließend - vorzugsweise - durch einen beheizten Wattefilter geleitet. In diesem Wattefilter werden evtl. mitgerisse ne Partikel durch die Verringerung der Strömungsgeschwindigkeit sowie durch die Filterwirkung der Watte abgeschieden. Danach durchströmt das Probegas in einen beheizten Gassättiger. Der Gassättiger ist mit einem organischen Lösungsmittel, z. B. Dekalin, gefüllt. Beim Durchströmen des Gassättigers wird das Probegas mit dem Lösungsmittel entsprechend dem Sättigungsdampfdruck gesättigt.Experiments with raw coke oven gas have shown that the electrostatic precipitator at a temperature of approx. 80 ° C a significantly higher efficiency than at low has higher temperatures. In the heated electrostatic filter 99.99% of the Solids separated. The test gas is then - preferably - by a heated cotton filter passed. This cotton filter may be entrained ne particles by reducing the flow velocity as well as by the The filter effect of the cotton is deposited. Then the sample gas flows into one heated gas saturator. The gas saturator is mixed with an organic solvent, e.g. B. Dekalin, filled. When flowing through the gas saturator, the sample gas is added saturated with the solvent according to the saturation vapor pressure.
Das Probegas wird nun in einen indirekten Kühler geführt, in dem der Wasser dampf und das in dem Probegas enthaltene Naphthalin auskondensiert werden. Das Naphthalin verstopft den Kühler nicht, da es durch das in dem Sättiger aufge nommene Lösungsmittel, das in dem Kühler ebenfalls kondensiert, gelöst und ab gewaschen wird. Das Naphtalin kann auch mit einer mit Lösungsmittel gefüllten Waschflasche abgeschieden werden.The sample gas is now fed into an indirect cooler in which the water steam and the naphthalene contained in the sample gas are condensed out. The naphthalene does not clog the cooler as it is opened in the saturator taken solvent, which also condenses in the cooler, dissolved and off is washed. The naphthalene can also be filled with a solvent Wash bottle to be separated.
Das so gereinigte Probegas kann nun kontinuierlich mittels der Gaspumpe zur gewünschten Onlineanalytik sowie zur parallel geschalteten Sauerstoffmessung gefördert werden.The sample gas cleaned in this way can now be continuously fed to the gas pump desired online analysis and for parallel oxygen measurement be promoted.
In der Probenahmevorrichtung kann es vorkommen, daß ein eventueller Unterdruck an der Probenahmestelle sich bis in den Bereich des Gassättigers auswirkt. Deshalb ist gemäß einer Weiterbildung der Erfindung vor dem Gassättiger eine Lösungsmittelfalle vorgesehen, die mitgerissenes Lösungsmittel bei Druckschwan kungen abscheidet.A possible negative pressure may occur in the sampling device at the sampling point affects the area of the gas saturator. Therefore, according to a further development of the invention, there is a gas saturator Solvent trap provided, the entrained solvent in pressure swan deposits.
Das erfindungsgemäße Probenahmesystem ist durch eine Verriegelungskette ge gen Explosion geschützt. Bei einem plötzlichen Druckanstieg innerhalb des im Unterdruck betriebenen Probenahmesystems würde sich der gemessene Druck in Richtung 0 mm Wassersäule bewegen. Durch einen sogenannten PSA-Schalter (Pressure Switch Alarm) würde die Vorrichtung, d. h. die Gaspumpe und das Elek trofilter sofort abgeschaltet und das Magnetventil am Eintritt der beheizten Probe nahmeleitung geschlossen, so daß keine Verbindung mehr zur Rohgasleitung be steht.The sampling system according to the invention is ge by a locking chain protected against explosion. If there is a sudden increase in pressure within the Vacuum operated sampling system would be the measured pressure in Move towards the 0 mm water column. Through a so-called PSA switch (Pressure Switch Alarm) the device, i. H. the gas pump and the elec trofilter switched off immediately and the solenoid valve at the inlet of the heated sample local line closed, so that no connection to the raw gas line be stands.
Die Verriegelungskette schließt sich ebenfalls automatisch, falls bei der Sauer stoffmessung ein Sauerstoffgehalt von < 4% gemessen wird. Außerdem kann eine Alarmmeldung (Signallampe und Hupton) sowie ein Abschaltsignal von der Probe nahmeeinrichtung zu den technischen Einrichtungen wie beispielsweise der elek trostatischen Entteerung einer Kokereianlage gesendet werden.The locking chain also closes automatically, if with the Sauer an oxygen content of <4% is measured. In addition, a Alarm message (signal lamp and horn) and a switch-off signal from the sample device for the technical equipment such as the elek trostatic de-emptying of a coking plant.
Nach dem Durchlaufen der ON-LINE-Analysengeräte kann das Probegas wieder in die Probegasleitung zurückgeführt werden.After passing through the ON-LINE analyzers, the sample gas can be used again be returned to the test gas line.
Mit Hilfe des erfindungsgemäßen Probenahmesystems ist es möglich, eine konti nuierliche Beprobung von stark mit Feststoffen und Teer verunreinigten Gasen vorzunehmen. Bei einer Beprobung von Koksofenrohgas führt dies zu einer we sentlichen Erhöhung der Sicherheit, da durch die Probenahme mit der erfindungs gemäßen Probenahmevorrichtung in dem ca. 80°C heißen, wasserdampfgesät tigten Gasstrom einer Kokereianlage die zur Überwachung von Anlagenteilen er forderliche kontinuierliche Sauerstoffmessung gewährleistet ist. With the aid of the sampling system according to the invention, it is possible to obtain a continuous Nuclear sampling of gases heavily contaminated with solids and tar to make. When sampling coke oven raw gas, this leads to a white considerable increase in security, since sampling with the fiction appropriate sampling device in the approx. 80 ° C hot, steam-sown gas flow from a coking plant was used to monitor parts of the plant required continuous oxygen measurement is guaranteed.
Außerdem ist es möglich, eine kontinuierliche Feststoffbestimmung durch Absie ben und Rückwaage der im Elektrofilter abgeschiedenen Feststoffe mit Hilfe eines Siebbodens und einer Waage durchzuführen. In Verbindung mit einer Gasmen genmessung kann die Feststoffkonzentration des Probegases bestimmt werden.It is also possible to carry out a continuous solids determination using Absie ben and backweighing of the solids separated in the electrostatic filter with the help of a Sieve bottom and a balance. In connection with a gasmen the solid concentration of the sample gas can be determined.
Gemäß einer Weiterbildung der Erfindung kann die Probenahmevorrichtung in einem Transportkoffer angeordnet werden. Der Transportkoffer ist beheizbar, so daß eine separate Beheizung des Elektrofilters und des Gassättigers nicht erfor derlich ist.According to a development of the invention, the sampling device in be arranged in a transport case. The transport case is heated, so that separate heating of the electrostatic precipitator and the gas saturator is not necessary is such.
Für die kontinuierliche Probenahme ist es nötig, daß sowohl der Elektrofilterablauf als auch der Kühler mit einem kontinuierlichen Entleerungssystem ausgestattet sind.For continuous sampling, it is necessary that both the electrostatic filter drain as well as the cooler with a continuous drain system are.
Mit der erfindungsgemäßen Probenahmevorrichtung ist eine kontinuierliche Pro benahme bei allen stark staubhaltigen Gasen möglich, wie sie z. B. bei der Müll verbrennung, der Vergasung, der Schwerölfeuerung, in Kohlefeuerungsanlagen und bei Hochofengasen anfallen.With the sampling device according to the invention is a continuous pro possible for all gases with a high dust content, such as z. B. in the trash combustion, gasification, heavy oil firing, in coal firing plants and occur with blast furnace gases.
Wenn das Probegas unter Druck steht, kann sich unter Umständen eine Gaspum pe erübrigen.If the test gas is under pressure, a gas pump may be present pe unnecessary.
Bei Gasen, die keine Naphthalin enthalten, erübrigt sich ebenso der Einsatz eines Gassättigers.For gases that do not contain naphthalene, there is also no need to use one Gas saturator.
Die vorgenannten, sowie die beanspruchten und in dem Ausführungsbeispiel be schriebenen, erfindungsgemäß zu verwendenden Bauteile unterliegen hinsichtlich ihrer Größe, Formgestaltung, Materialauswahl und technischen Konzeption keinen besonderen Ausnahmebedingungen, so daß die in dem jeweiligen Anwendungs gebiet bekannten Auswahlkriterien im Rahmen der Ansprüche uneingeschränkt Anwendung finden können.

Behind the electrostatic filter 3 there is a cotton filter 5 , which is also designed to be heatable. Then the sample gas flows through a gas saturator 6 with decalin 6 a, which is preceded by a solvent trap 6 '. The sample gas saturated with decalin 6 a flows into a cooler 7 , in which the condensation takes place. The cooler 7 is seen with a continuous emptying T ver. The sample gas processed in this way can be fed to a continuous oxygen measurement 10 via a gas pump 8 . Further ON-LINE gas measuring devices 9 are connected via a further line.
In der Fig. 2 ist ein Elektrofilter 11 mit integrierter Feststoffbestimmung dargestellt. Das Elektrofilter 11 besteht aus einem zylindrischen Mantel 12, der als Minuspol dient und einem Sprühdraht 13 mit Isolator 13'. Der zylindrische Mantel 12 weist eine Abdeckung 14 auf. Am unteren Teil des zylindrischen Mantels 12 ist ein Ko nus 15 mit einem Ablauf 17 angeordnet, der durch einen Absperrhahn 16 ge schlossen werden kann. Das Probegas tritt durch einen Gaseintrittsstutzen 18 ein, der in Richtung des Konus 15 geöffnet ist. Durch den als Diffusor wirkenden Konus 15 des Elektrofilters 11 tritt eine Verringerung der Strömungsgeschwindigkeit ein, wodurch bereits eine Vorabscheidung von groben Partikeln in dem Probegas er folgt. Das Probegas verläßt das Elektrofilter 11 über einen Gasaustrittsstutzen 19, der am oberen Ende des zylindrischen Mantels 12 des Elektrofilters 11 angeordnet ist.In FIG. 2, an electrostatic precipitator 11 is shown with an integrated solid determination. The electrostatic filter 11 consists of a cylindrical jacket 12 which serves as a negative pole and a spray wire 13 with an insulator 13 '. The cylindrical jacket 12 has a cover 14 . At the lower part of the cylindrical shell 12 , a Ko nus 15 is arranged with a drain 17 , which can be closed by a shut-off valve 16 GE. The sample gas enters through a gas inlet connection 18 which is open in the direction of the cone 15 . The cone 15 of the electrostatic precipitator 11 , which acts as a diffuser, results in a reduction in the flow velocity, as a result of which a preliminary separation of coarse particles in the sample gas occurs. The sample gas leaves the electrostatic precipitator 11 via a gas outlet connection 19 which is arranged at the upper end of the cylindrical jacket 12 of the electrostatic precipitator 11 .
Unter dem Konus 15 des Elektrofilters 11 ist ein Sammelbehälter 20 angeordnet. Der Sammelbehälter 20 nimmt die in dem Elektrofilter 11 abgeschiedenen Stoffe über einen Ablauf 17 auf. Der Sammelbehälter 20 kann über eine Entleerung 22 mit Absperrhahn 21 auf einen Siebboden 24 mit Waage 25 entleert werden. Die Entleerung erfolgt unter Stickstoff, der durch eine Stickstoffzufuhr 23 in den Sam melbehälter 20 geführt wird. Da in dem Elektrofilter 11 99,99% der mit dem Pro begas mitgeführten Feststoffe abgeschieden werden, besteht somit die Möglichkeit den Feststoffgehalt des Probegases durch Wägung kontinuierlich zu bestimmen. A collecting container 20 is arranged under the cone 15 of the electrostatic filter 11 . The collecting container 20 receives the substances separated in the electrostatic filter 11 via an outlet 17 . The collecting container 20 can be emptied via a drain 22 with a shut-off valve 21 onto a sieve tray 24 with a balance 25 . The emptying takes place under nitrogen, which is passed through a nitrogen supply 23 in the Sam mel container 20 . Since 11 99.99% of the solids carried with the sample gas are separated in the electrostatic precipitator 11, there is thus the possibility of continuously determining the solids content of the sample gas by weighing.
