Description
JAVNI SISTEM ZA GAŠENJE Z DOVAJANJEM ZRAKA Z ZMANJŠANIM ODSTOTKOM KISIKA NA MESTO POŽARAPUBLIC FIGHTING SYSTEM FOR AIRWORTHINESS WITH REDUCED ODOR OF OILS TO FIRE
Predmet izuma je javni sistem za gašenje z dovajanjem zraka z zmanjšanim odstotkom kisika, na mesto požara, ki še omogoča preživetje in onemogoča gorenje do prihoda gasilcev. Gre za drugačen način hranjenja gasilnih plinov. Običajno so se hranili gasilni plini v jeklenkah pod visokim pritiskom ta izum pa omogoča hrambo gasilnih plinov v cevovodu pri nižjih tlakih, kar poveča količino shranjenih plinov in ceno na enoto shranjenega plina.The object of the invention is a public system for extinguishing air with a reduced percentage of oxygen, a place of fire that still allows survival and prevents burning until the arrival of firefighters. It is a different way of storing fire extinguishers. Typically, flammable gases in high-pressure gas cylinders are stored and this invention allows the storage of fire extinguishing gas in the pipeline at lower pressures, which increases the amount of stored gas and the price per unit of stored gas.
Zaradi ekološke nesprejemljivosti uničevanja ozonske plasti so prepovedane halogenirane snovi za gašenje, uporaba dušika in ogljikovega dioksida pa je lahko nevarna za ljudi, saj jim ne omogoča več dihanja in jih zaduši.Due to the ecological unacceptability of ozone depletion, halogenated extinguishing agents are prohibited, and the use of nitrogen and carbon dioxide can be hazardous to humans, since they do not allow them to breathe and choke them anymore.
Sistem omogoča, da preko posebne ali že obstoječe gasilne napeljave, ventilacijskega sistema ali podobnih napeljav, dovajamo mešanico zraka z zmanjšanim odstotkom kisika na mesto požara in na ta način ustvarimo okolje z zmanjšanim odstotkom kisika na mestu požara in preprečimo širjenje požara ter njegovo pogasitev.The system enables us to supply a mixture of air with a reduced percentage of oxygen to the place of fire through a special or already existing fire extinguisher, ventilation system or similar installations, thus creating an environment with a reduced percentage of oxygen at the site of the fire and preventing the spread of the fire and its extinguishing.
Tehnični problem, ki ga predložen izum uspešno rešuje, je preprečevanje širjenja požara in njegova pogasitev predvsem na mestih, kjer zaradi specifičnih pogojev (visoke stavbe, nedostopnost gasilnih vozil ipd.) ni možno gašenje s standardnimi načini gašenja ali pa je to prepočasno in zato ne dovolj učinkovito.The technical problem successfully solved by the present invention is to prevent the spread of fire and its extermination, especially in places where, due to specific conditions (high building, inaccessibility of fire extinguishing vehicles, etc.), it is not possible to extinguish with standard fire extinguishers or it is too slow and therefore not effective enough.
Kot kažejo minuli požari predorih in v visokih zgradbah je težava gasilcev v tem, da ne morejo pravočasno priti v te objekte, gašenje pa je ob polnem razvoju požara onemogočeno.As shown by the fires of tunnels and high buildings, the problem of firefighters is that they can not get to these facilities in a timely manner, and the fire extinguishing is not possible with the full development of the fire.
Požari, kjer je na pogorišču večji odstotek kisika kot običajno (primer izpuščanje inštalacije za kisik v bolnišnici) se širijo pospešeno. Podoben efekt je ob močnem vetru v gozdnem požaru ali v predoru, tako imenovan »kaminski efekt«. V jedrskih podmornicah in rudnikih gasijo požare z manjšim odstotkom kisika v zraku, kar preprečuje gorenje in razvoj požarov.Firing, where at a high point of oxygen, a greater percentage of oxygen than usual (for example, the oxygen installation in the hospital) is spreading rapidly. A similar effect is due to strong winds in a forest fire or in a tunnel, the so-called "fire effect". In nuclear submarines and mines fire fires with a small percentage of oxygen in the air, which prevents the burning and development of fires.
Običajno se v prostor spušča mešanica iz jeklenk pod visokim tlakom različnih mešanic plinov. Ob tem lahko zlahka pride do prenizke koncentracije kisika v prostoru, ki je lahko nevarna za ljudi in živali, ki se znajdejo tam. V zraku je običajno 78,084 % dušika (N2), 20,947 % kisika (O2), 0,934 % argona (Ar) in 0,033 % ogljikovega dioksida (CO2). Ljudje lahko še preživijo pri do 12% kisika v ozračju, medtem ko požar ugasne pri 16-17%. V nadaljevanju bom opisal izvedbene primere uporabe sistema za gašenje z dovajanjem zraka z zmanjšanim odstotkom kisika na mesto požara in sicer izvedbo požarnega sistema po izumu pri pri gašenju visokih zgradb, gašenju javnih zgradb, posebnih objekotv in pri gašenju v predoru.Usually, a mixture of high pressure cylinders of various gas mixtures is lowered into the room. In addition, it can easily cause too little oxygen concentration in the room, which can be dangerous for people and animals that find themselves there. The air is usually 78.084% nitrogen (N2), 20.947% oxygen (O2), 0.934% argon (Ar) and 0.033% carbon dioxide (CO2). Humans can still survive up to 12% of oxygen in the atmosphere, while the fire goes off at 16-17%. In the following, I will describe the implementation examples of the use of an airborne fire-extinguishing system with a reduced percentage of oxygen to the site of the fire, namely the implementation of a fire system according to the invention in quenching high buildings, extinguishing public buildings, special facilities and shutting off in the tunnel.
Izvedbeni primeri sistema za gašenje z dovajanjem zraka z zmanjšanim odstotkom kisika na mesto požara, se razlikujejo glede na mesto uporabe, kakor tudi na že obstoječo infrastrukturo. Tako je možno zrak z zmanjšanim odstotkom kisika v predor vpihniti v požarno cono iz cevi, ki je hkrati hranilnik zraka z zmanjšanim odstotkom kisika, pri gašenju javnih in visokih zgradbah pa lahko zrak z zmanjšanim odstotkom kisika dovajamo preko že obstoječega sprinkler sistema.Implementation examples of an airborne fire-extinguishing system with a reduced percentage of oxygen to the site of a fire vary depending on the place of use, as well as on the existing infrastructure. Thus, the air with a reduced percentage of oxygen into the tunnel can be blown into the fire zone of the pipe, which is at the same time an air storage with a reduced percentage of oxygen, while in the extinguishing of public and high buildings, air with a reduced percentage of oxygen can be supplied via the already existing sprinkler system.
Izvedbo sistema po izumu na različnih objektih bom prikazal na osnovi zvedbenih primerov in slik, od katerih kaže: slika 1 shematski prikaz izvedbe sistema po izumu pri gašenju požara v visokih zgradbah; slika 2 shematski prikaz izvedbe sistema po izumu pri gašenju požara v predoru; slika 3 shematski prikaz izvedbe sistema po izumu pri gašenju požara v sistemu javnih zgradb.The embodiment of the system according to the invention on various objects will be shown on the basis of illustrative examples and images, of which it is shown: FIG. 1 is a schematic view of a system embodiment according to the invention in the fire extinguishing in high buildings; FIG. 2 is a schematic representation of the embodiment of a system according to the invention in the fire extinguishing in a tunnel; Figure 3 is a schematic representation of the embodiment of a system according to the invention in the fire extinguishing system of public buildings.
Izkušnje, ki jih prinašajo požari v visokih zgradbah kažejo, da so stavbe prerasle zmožnosti gašenja in da so obstoječi sistemi tako rekoč slabo uporabni in dragi. Običajna draga preventiva pred požarom je danes predpisan šprinkler in požarna ventilacija, ki naj bi v primeru požara delovala consko in naj se po njej naj ne bi širil dim in požar. V igralnicah imajo ponekod povečan odstotek kisika, da bi se ljudje bolje počutili in ostali bolj budni in porabili več denarja v igralnici. Kot je pokazal požar v kuhinji hotela z igralnico so bile smrtne žrtve na vrhu hotela zaradi napačnega širjenja strupenih plinov. Poleg tega pa je požar še bolj nesmiselno gasiti z vodo, ker z njo ne smemo gasiti številnih snovi, ker voda pospešuje požar ali pa povzroči nevarnost električnega udara.The experience of fires in high buildings shows that buildings have extinguished their capabilities and that existing systems are practically poorly used and expensive. The usual expensive fire prevention is now prescribed by the sprinkler and fire ventilation, which should be in the zone of fire in the event of fire and should not spread smoke and fire. In casinos, there is an increased percentage of oxygen in order to make people feel better and stay awake and spend more money in the casino. As the fire in the kitchen of a hotel with a casino showed, fatalities were at the top of the hotel due to the wrong spread of toxic gases. In addition, the fire is even more meaningless to quench with water, because it should not extinguish many substances because water accelerates the fire or causes a risk of electric shock.
Novejši sistemi za gašenje poslovnih stavb, stanovanj in hotelov so šprinkler na vodno meglo, ki pa zahteva popolnoma nove inštalacije, ki so visokotlačne in iz nerjavečega jekla in sistem je občutljiv na zamašitev šob. Črpalke zahtevajo veliko energije in je tudi drago vzdrževanje sistema v stalni pripraljenosti.Newer systems for extinguishing commercial buildings, apartments and hotels are sprinkler on water fog, which requires completely new installations, which are high pressure and stainless steel, and the system is sensitive to clogging of nozzles. Pumps require a lot of energy and expensive maintenance of the system in constant rejection.
Obstaja pa še sistem gašenja z posebnimi plinskimi mešanicami predvsem za gašenje računalniških centrov, ki pa so zelo dragi sistemi, ker je spravljen gasilni plin v visokotlačnih jeklenkah in industrija izkorišča dejstvo, da je takih sistemov relativno malo in da so obvezni v določenih prostorih. V visokih stavbah gasilske lestve sežejo omejeno, do največ 60 m, problem pa je, da so ob zgradbah parki ali pa podzemni prostori in je visoke lestve nemogoče dovolj trdno podpreti. Lestve ovira dim in le stežka bi rešili več ljudi. Poleg tega pa so ozke ceste in parkirana vozila, kar otežuje dostop. Ker tudi črpalke ne delujejo dovolj visoko smo omejeni z višino, druga ovira pa je seveda močan curek in dim po možnosti dim, ki spreminja smer glede na smer vetra in dinamiko požara ter toplotno sevanje, ki ovira delo na višinski lestvi ali ploščadi. Ogenj in gašenje povzroči ogromno škodo in uničenje. Gašenje zraka z zmanjšanim odstotkom kisika je tako rekoč podaljšanje gasilskih lestev saj omogoča, da se vsi varno umaknejo iz objekta in gasilci varno pristopajo, na lokacijo začetnega požara in je mogoče tudi ugotoviti razloge za požar.There is also a system of extinguishing with special gas mixtures, primarily for quenching computer centers, which are very expensive systems because the gas is stored in high pressure cylinders and the industry uses the fact that such systems are relatively small and that they are mandatory in certain rooms. In high-rise firefighting buildings, they are limited to a maximum of 60 m. The problem is that there are parks or underground spaces next to buildings, and high ladders can not be sufficiently backed up. The ladder hinders smoke and it is difficult to save more people. In addition, narrow roads and parked vehicles make access difficult. Since the pumps do not work high enough, we are limited by height, and the second obstacle is, of course, a powerful jet and smoke, possibly smoke, which changes the direction in relation to the direction of the wind and the dynamics of the fire, and the thermal radiation that hampers work on the elevation ladders or platforms. Fire and quenching cause enormous damage and destruction. Extinguishing the air with a reduced percentage of oxygen is practically an extension of firefighting ladders, as it enables all to safely withdraw from the facility and the firefighters safely approach the location of the initial fire and it is also possible to determine the reasons for the fire.
Izvedba sistema po izumu pri gašenju požara v visokih zgradbah je prikazana na sliki 1. Sistem je mogoče priključiti na obstoječa šprinkler omrežja in ventilacijske sisteme brez večjih stroškov. Visoke zgradbe morajo imeti po novejših predpisih vgrajeno gasilno napravo. V primeru uporabe sistema po izumu je priključitev izvedena preko priključnega jaška 2 z ventili in napravo za kontrolo plina. V zgradbi je razvejano šprinkler omrežje 3 s šprinkler šobami 4. Poleg tega je v zgradbi tudi klimatska naprava 6 z etažnimi izpusti 7.The embodiment of the system according to the invention in the fire extinguishing in high buildings is shown in Figure 1. The system can be connected to an existing sprinkler network and ventilation systems without major costs. High buildings must have a fire extinguisher installed according to the latest regulations. In the case of the use of the system according to the invention, the connection is carried out via a connecting shaft 2 with valves and a gas control device. In the building there is a branched sprinkler network 3 with sprinkler nozzles 4. In addition, the building also has an air conditioner 6 with floor drains 7.
Pri začetnem požaru 8 je aktiviran najbljižji šprinkler 9, skozi katerega dovajamo zrak z zmanjšanim odstotkom kisika, ki umiri in lahko tudi ugasi začetni požar. Podobno lahko izvedemo tudi skozi etažne izpuste 7 klimatske naprave 8.At the initial fire 8, the closest sprinkler 9 is activated, through which air is supplied with a reduced percentage of oxygen that calms down and can also extinguish the initial fire. Similarly, it can also be carried out through the floor drains 7 of the air conditioner 8.
Zaradi dokaj velike dolžine javnega gasilnega omrežja je tudi volumen potrebnega zraka z zmanjšanim odstotkom kisika velik. Če je potrebno pa se lahko na določenih mestih omrežja nahajajo dodatni hranilniki zraka z zmanjšanim odstotkom kisika. Omrežje je sekcijsko deljeno, kar omogoča popravila ali sekcijske tlačne preizkuse.Due to the relatively large length of the public fire extinguishing network, the volume of the required air with a reduced percentage of oxygen is high. If necessary, additional air storage systems with a reduced percentage of oxygen can be located at certain network sites. The network is sectionally divided, allowing for repairs or section pressure tests.
Vsekakor je potrebna zelo dobra detekcija in pa primerna količina mešanice z zagotovljenim minimalnim odstotkom kisika, ki omogoča preživetje tako, da ne more priti do žepov s premajhno koncentracijo kisika.In any case, a very good detection is required and a suitable amount of the mixture with a guaranteed minimum percentage of oxygen that allows survival so that it can not reach the pockets with too little oxygen concentration.
Na sliki 2 sta prikazani dve možni izvedbi uporabe sistema za gašenje z dovajanjem zraka z zmanjšanim odstotkom kisika po izumu. V predorski cevi 10 že poteka cevovod 11 javnega gasilnega sistema na katero so priključeni izpustni ventilni moduli 12. Na obeh portalih imamo standardni tlačni posodi 13 in pa polnilno mesto.In Fig. 2, two possible embodiments of the use of an airborne exhausting system with reduced oxygen content according to the invention are shown. In the tunnel tube 10, there is already a pipeline 11 of the public extinguishing system to which the discharge valves 12 are connected. On both ports there are standard pressure vessels 13 and a filling station.
Po prvem izvedbenem primeru je sistem mogoče napolniti s posebnim kompresorjem 13, ki s pomočjo membran ločuje kisik od dušika. Kar pa je dokaj drago in ni smiselno, ker tak sistem potem več let ne obratuje ali pa relativno zelo malo, samo za dopolnjevanje izgub, ki nastajajo zaradi netesnosti.According to the first embodiment, the system can be charged with a special compressor 13 which separates the oxygen from the nitrogen by means of the membrane. However, it is rather expensive and it does not make sense because such a system is not operating for several years or relatively few, only to supplement the losses that result from leakiness.
Druga možnost pa je da polnimo sistem z utekočinjenim plinom in ga ustrezno uplinimo pred polnitvijo tako, da se dušik in kisik mešata v plinasti fazi. V tem primeru je na tlačno posodo 13 priključen dovod 15 tekočega dušika s tekočim kisikom in dovod 16 toplotnega izmenjevalca za uplinjanje plina. Mogoče je tudi dodajati komprimiranemu zrako samo dušik, je pa težje zagotoviti natančen odstotek kisika v taki mešanici, kar lahko privede do zadušitve ljudi ali do neučinkovitega gašenja.Alternatively, it is possible to fill the liquefied gas system and fumigate it properly before filling, so that nitrogen and oxygen are mixed in the gaseous phase. In this case, a liquid supply nitrogen stream 15 with liquid oxygen is connected to the pressure vessel 13 and the heat exchanger gas inlet 16 is connected. It is also possible to add nitrogen to the compressed air, but it is more difficult to provide a precise percentage of oxygen in such a mixture, which can lead to people suffocating or to ineffective quenching.
Na cevovodu 11 so nameščene ustrezne šobe in ventili 12. Prva vrsta ventilov je krogličnih in jih je mogoče daljinsko odpirati ali zapirati, kar omogoča ob manjšem požaru prihranek plina. Drugi ventili pa so membranski in se jih odpira z posebnim daljinskim vžigom in jih ni mogoče zapreti. Ob požaru ventilacija ustvari zračno zaveso v celotni širini predora in nadtlak, ki nastaja zaradi vpihovanja gasilnega zraka z zmanjšanim odstotkom kisika, preprečuje dotok zraka preko zračnih zaves. Ko tlak ustrezno počasi pada v cevovodu in se zaradi učinkovanja zračnih zaves izenači tudi tlak na obeh straneh požarne cone, je gasilni zrak v požarni coni stabilen in tako se še podaljša učinek gašenja. Prednost tega gašenja je, da deluje trenutno in da ob znižanju ravni kisika znižamo hkrati tudi temperaturo zaradi ekspanzije plina. Poleg tega pa je občutno manj dima in se vidljivost zaradi vpihovanja čistega zraka celo izboljša v požarni coni. Tako lahko omejimo požar tja do 30 minut do prihoda gasilcev.The corresponding nozzles and valves 12 are fitted on the pipeline 11. The first type of valves are ballast and can be remotely opened or closed, which allows for lower gas savings. The other valves are membrane and are opened with special remote ignition and can not be closed. In the event of fire, ventilation creates an air curtain in the entire width of the tunnel and the overpressure resulting from the blowing of fire fighting air with a reduced percentage of oxygen, prevents air flow through air curtains. When the pressure slowly drops down in the pipeline and the pressure on both sides of the fire zone is equalized due to the action of the air curtains, the fire extinguishing air in the fire zone is stable and thus the extinction effect is extended. The advantage of this quenching is that it works at the present time and that, when the oxygen level is lowered, the temperature due to the expansion of the gas is reduced. In addition, there is considerably less smoke, and clean air visibility is even improved in the fire zone. So we can limit the fire up to 30 minutes until the firefighters arrive.
Izvedba sistema po izumu pri gašenju požara v sistemu javnih zgradbah 18, kot so hoteli, muzeji, industrijski objekti, trgovine, stanovanja, skladišča, kinodovrane ipd., je prikazana na sliki 3.The embodiment of the system according to the invention in the fire extinguishing system in public buildings 18, such as hotels, museums, industrial buildings, shops, housing, warehouses, kinodovarna etc., is shown in Figure 3.
Sistem razvit za gašenje predorov je mogoče koristno uporabiti kot javno gasilno omrežje, ki ga sestavlja mestni cevovod, ki je na moč podoben plinovodu. Pri tem se v cevovodu 11 nahaja mešanica zraka z zmanjšanim odstotkom kisika. Ker je dolžina cevovoda 11 lahko dokaj dolga je tudi volumen velik. Če je potrebno se lahko na določenih mestih cevovoda 11 nahajajo dodatni hranilniki gasilnega plina. Sistem je sekcijsko deljen, kar omogoča popravila ali sekcijske tlačne preizkuse. Tak sistem je mogoče priključiti na obstoječa šprinkler omrežja in ventilacijske sisteme brez večjih stroškov. Sistem je polnjen med 10 in 60 bari in ga je mogoče tudi pred vstopom v objekte 18 ustrezno reducirati.The system developed for tunnel extinguishing can be usefully used as a public fire-extinguishing network consisting of a city pipeline that is similar to a pipeline. In this case, there is a mixture of air with a reduced percentage of oxygen in the pipeline 11. Since the length of the pipeline 11 can be quite long, the volume is also large. If necessary, additional fire extinguishers may be located at certain points of the pipeline 11. The system is sectionally divided, allowing for repairs or section pressure tests. Such a system can be connected to the existing sprinkler network and ventilation systems without any major costs. The system is charged between 10 and 60 bars and can be reduced accordingly before entering the facilities 18.
Prednost sistema je, da je uporaben tudi za zelo velike prostore kot so dvorane, hangerji in deluje od spodaj navzgor, ker je gasilni zrak zaradi ekspancije težji. Kar je pomembno je zagotovitev ustreznega odvoda nadtlaka za odvod dima in zrak, ki ga mora gasilni trak izpodriniti. Torej obstoječa tehnika dimnih izpustov na strehi v ničemer ne ovira gašenja z zrakom in je sistem v celoti kompatibilen. V principu deluje kot »suhi šprinker« ki je napolnjen v krajih z nizko temperaturo z dušikom in ko pade tlak priteče še voda, ki je ustrezno zaščitena pred zmrzovanjem. Zato dejansko ni večjih neznank pri uporabi in že obstajajo tudi vsi ustrezni dokumenti in tehnične rešitve.The advantage of the system is that it is also useful for very large spaces, such as halls, hangers and bottom-up, because the fire extinguishing air is more difficult due to expansions. What is important is to ensure the proper drainage of the overpressure for the smoke and air outlet that the fire extinguisher must displace. Therefore, the existing flue gas exudation technique does not in any way interfere with air blasting and the system is fully compatible. In principle, it acts as a "dry sprinkler" which is filled in low-temperature nitrogen places and when the pressure drops, there is also water that is adequately protected against freezing. Therefore, there are in fact no major identities in use and there are already all relevant documents and technical solutions.
Prednost glede na suhi šprinkler je v tem, da je v sistemu za gašenje po izumu dovajan zrak z zmanjšanim odstotkom kisika in ni voda in ni dušik, kar zagotavlja preživetje tudi v zaprtih prostorih.The advantage over the dry sprinkler is that in the fire-extinguishing system according to the invention, air is supplied with a reduced percentage of oxygen and there is no water and there is no nitrogen, which ensures the survival even in indoor spaces.
Ob požaru se samostojno sproži gašenje ob povečani temperaturi, ko se zaradi vročine zdrobi - in aktivira šprinkler ampula, in sistem prične takoj delovati lokalno, lahko pa se dovaja tudi gasilni zrak v nadstropje skozi ventilacijski sistem. Stroški delnega ali celotnega polnjenja gasilnega sistema se obračunajo lastniku zgradbe 18, kjer je gorelo in ob tem vsi, ki so priključeni na omrežje plačujejo še mesečno ali letno pristojbino za stroške gradnje in vzdrževanja. Lastniki takih omrežji so običajno mesto, lahko tudi podjetja, za pravilno uporabo in nemoteno delovanje pa skrbijo pooblaščena podjetja ali gasilske enote, podobno kot skrbijo za servisiranje in delovanje gasilnih aparatov.In case of fire, the fire extinguishes at an increased temperature when the heat is crushed - and the sprinkler ampoule is activated, and the system starts to operate immediately locally, and fire extinguishing air can be delivered to the floor through the ventilation system. The cost of partial or full filling of the fire-fighting system is charged to the owner of the building 18 where it burned, and at the same time all those who are connected to the network pay a monthly or annual fee for the costs of construction and maintenance. The owners of such networks are usually a place, and companies can also be used for proper use and smooth operation by authorized companies or firefighters, similarly as they care for the servicing and operation of fire extinguishers.
