Description

Anordning for slukking av brann i spyleluftbeltet eller tilliggende deler på totaktsdieselmotorer. Device for extinguishing fires in the scavenging air belt or adjacent parts on two-stroke diesel engines.

Foreliggende oppfinnelse angår en anordning for slukking av brann ved hjelp av kullsyregass. The present invention relates to a device for extinguishing a fire using carbon dioxide gas.

Kullsyregass som oppbevares i flytende form på trykkflasker er meget anvendt som brannslukkingsmiddel, fordi kullsyregassen som sådan ikke underholder forbren-ningen og derved hindrer tilgang på surstoff, slik at en eventuell brann vil slukke. I de fleste tilfellene er det også hensiktsmessig ved slukking av brann at slukkings-midlet virker kjølende, og dette er da også tilfellet ved bruken av kullsyregass, da den flytende kullsyre ved ekspansjon fra kullsyreflasken får en meget lav temperatur. Carbon dioxide that is stored in liquid form in pressurized bottles is widely used as a fire extinguishing agent, because carbon dioxide as such does not support combustion and thereby prevents access to oxygen, so that any fire will be extinguished. In most cases, it is also appropriate when extinguishing a fire that the extinguishing agent has a cooling effect, and this is also the case when carbon dioxide gas is used, as the liquid carbon dioxide expands from the carbon dioxide bottle to a very low temperature.

Som nevnt er dette i mange tilfelle en As mentioned, in many cases this is one

fordel, men i andre tilfelle kan det være en ulempe, da mange gjenstander kan bli skadet ved for sterk kjøling, når gjenstan-den først er opphetet på grunn av brann eller av andre årsaker. Dette kan f. eks. være tilfellet ved brann i en motor, da man risikerer ødeleggelse av en motorblokk ved å skape sterke temperaturdifferanser in-nen blokken, slik at det oppstår spenninger i godset. advantage, but in other cases it can be a disadvantage, as many objects can be damaged by too strong cooling, once the object has been heated due to fire or for other reasons. This can e.g. be the case in the event of a fire in an engine, as there is a risk of destroying an engine block by creating strong temperature differences within the block, so that tensions arise in the goods.

Hensikten med foreliggende oppfinnelse er å hindre en slik uhensiktsmessig, lokal, brå avkjøling og dette oppnås ifølge oppfinnelsen ved at kullsyregassen etter at den har forlatt gassflasken, men før den frigjøres og rettes mot brannstedet opp-varmes i hensiktsmessig grad. Dette kan skje ved at kullsyregassen fra flasken ledes gjennom et varmekammer som kan være oppvarmet på forskjellig, hensiktsmessig måte, f. eks. elektrisk eller ved hjelp av brennere, coil osv. På denne måten oppnår man at man får temperert kullsyregassen før den rettes mot brannstedet, og mann oppnår dessuten den fordel at kullsyregassen ved oppvarmningen utvider seg ennå imer, får et øket volum og får derved evnen til å fordrive større mengder luft og dermed surstoff og blir altså mer effektiv med mindre anvendelse av kullsyre. Derved kan man samtidig oppnå en stor besparelse i anvendelse av kullsyregass, hvilket kan ha sin særlige betydning ombord på et større skip. The purpose of the present invention is to prevent such inappropriate, local, sudden cooling and this is achieved according to the invention by the carbon dioxide gas being heated to an appropriate degree after it has left the gas bottle, but before it is released and directed towards the fire. This can happen by passing the carbon dioxide gas from the bottle through a heating chamber which can be heated in a different, appropriate way, e.g. electrically or with the help of burners, coils, etc. In this way, you achieve that you get the carbon dioxide gas tempered before it is directed towards the fire, and you also get the advantage that the carbon dioxide gas expands even more when heated, gains an increased volume and thereby gains the ability to to expel larger quantities of air and thus oxygen and thus becomes more efficient with less use of carbonic acid. Thereby, at the same time, a large saving can be achieved in the use of carbon dioxide gas, which can be particularly important on board a larger ship.

Særlig hensiktsmessig er denne frem-gangsmåte i forbindelse med to-takts-die-sel-motorer, idet det er en kjent sak at det ofte kan oppstå brann i spylelufttilførse-len i det såkalte spyleluftsbelte som er anbrakt på tvers av imotorens sylinder. Det er kjent å forbinde spyleluftsbeltet med kull-syrebeholderen, slik at denne brann kan slukkes ved å tilføre kullsyre, men man har da den ulempe at kullsyren ved sin ekspansjon får meget lav temperatur, og det parti av sylindrene som befinner seg i kontakt med spyleluftbeltet vil da bli brå-kjølt og man får forskjellige temperaturer i sylindernes forskjellige deler, hvilket fremkaller spenninger i godset, som kan fremkalle ødeleggelser i sylinderen. This procedure is particularly appropriate in connection with two-stroke diesel engines, as it is a well-known fact that a fire can often occur in the scavenge air supply in the so-called scavenge air belt which is placed across the engine's cylinder. It is known to connect the scavenging air belt to the carbon dioxide container, so that this fire can be extinguished by adding carbonic acid, but this has the disadvantage that the carbon dioxide gets a very low temperature during its expansion, and the part of the cylinders that is in contact with the scavenging air belt will then be suddenly cooled and you get different temperatures in the different parts of the cylinders, which causes tensions in the goods, which can cause destruction in the cylinder.

Ifølge oppfinnelsen hindres dette ved at man imellom kullsyreflasken og spyleluftbeltet anordner et kammer som kullsyregassen passerer gjennom før den kommer inn i spyleluftbeltet, og dette kammer er forsynt med egnede oppvarmningsan-ordninger hvor varmen kan fåes fra f. eks. motorens kjølevann, dens kjøleolje eller avgasser. Videre kan man anvende hjelpedamp eller elektriske oppvarmningsele-menter. Ved passende valg av temperatur i dette varmekammer kan man da bringe kullsyregassen opp til den ønskede temperatur før den kommer i kontakt med motorens sylindre. According to the invention, this is prevented by arranging a chamber between the carbon dioxide bottle and the purge air belt through which the carbon dioxide gas passes before it enters the purge air belt, and this chamber is provided with suitable heating devices where the heat can be obtained from e.g. the engine's cooling water, its cooling oil or exhaust gases. You can also use auxiliary steam or electric heating elements. By choosing the appropriate temperature in this heating chamber, the carbon dioxide gas can then be brought up to the desired temperature before it comes into contact with the engine's cylinders.

For at oppfinnelsen lett skal kunne forstås, skal den i det følgende forklares ved 'hjelp av tegningen, hvor In order for the invention to be easily understood, it will be explained in the following with the help of the drawing, where

figur 1 skjematisk viser et oppriss av en to-takts-dieselmotor og Figure 1 schematically shows an elevation of a two-stroke diesel engine and

figur 2 viser samme motor i endeopp-riss. Figure 2 shows the same engine in an end view.

1, 2, 3 og 4 viser fire sylindre hvorpå det er anbrakt et spyleluftbelte 5. Dette spyleluftbelte står naturligvis på vanlig måte i forbindelse med en tilførsel (ikke vist) for spyleluft, og er dessuten ved hjelp av et rør 6 forbundet med en kullsyreflaske 7. Mellom røret 6 og spyleluftbeltet 5 er det anordnet et varmekammer 8 forsynt med en oppvarmningsanordning, f. eks. en varmespiral 9, som kan føre kjølevann, kjøleolje, avgass eller hjelpedamp. Iste- 1, 2, 3 and 4 show four cylinders on which a flushing air belt 5 is placed. This flushing air belt is of course connected in the usual way to a supply (not shown) for flushing air, and is also connected by means of a pipe 6 to a carbon dioxide bottle 7. Between the pipe 6 and the purge air belt 5, a heating chamber 8 is arranged, equipped with a heating device, e.g. a heating coil 9, which can carry cooling water, cooling oil, exhaust gas or auxiliary steam. Ice cream-

denfor en slik rørspiral kan det også bru-kes elektriske varmeelementer. therefore, such a tube spiral can also be used with electric heating elements.

Når ventilen 10 åpnes, vil kullsyre strømme gjennom røret 6 og ekspanderer i kammeret 8, og vil derved avkjøles sterkt, men vil av varmespiralen 9 atter varmes opp og utvide seg mer før den strømmer inn i spyleluftbeltet 5. When the valve 10 is opened, carbon dioxide will flow through the pipe 6 and expand in the chamber 8, and will thereby cool down greatly, but will be heated again by the heating coil 9 and expand more before it flows into the purge air belt 5.
