91625 5 Såilio ympåristolle haitallisia nesteitå vårten Behållare for miljofarliga våtskor91625 5 Storage of environmentally harmful liquids Behållare for miljofarliga våtskor
Keksinto koskee såilidtå ympåristolle haitallisten nesteiden såilyttåmistå vårten. Tarkem-min sanottuna keksinto koskee kaksoisvaipallista sailiotå, josta ympåristolle haitallisten nesteiden pååsy såilidvuotojen johdosta ympåristoon on estetty.The invention relates to the storage of liquids harmful to the environment. More specifically, the invention relates to a double-jacketed silo from which the entry of liquids harmful to the environment into the environment due to silk leaks is prevented.
10 Monien ympåristolle haitallisten nesteiden varastointi maanpåållisisså tai maanalaisissa varastosåilioisså muodostaa ongelman. Såilion puhjetessa esimerkiksi korroosion johdosta såilidn sisålto pååsee vuotamaan ympåristoon ja esimerkiksi saastuttamaan pohjavesiå. Usein ja varsinkin maanalaisissa såilioisså vuodot havaitaan vasta pitkien aikojen kuluttua, jolloin huomattavia mååriå haitallisia aineita pååsee valumaan ulos ja saastuttamaan 15 ympåristdå ja pohjavesiå.10 The storage of many environmentally harmful liquids in above-ground or underground storage tanks is a problem. When a tank breaks out, for example due to corrosion, the contents of the tank can leak into the environment and, for example, contaminate groundwater. Often, and especially in underground silos, leaks are only detected after a long period of time, when considerable amounts of harmful substances can escape and contaminate the environment and groundwater.
On tunnettua kåyttåå kaksoisvaipallisia såiliditå esimerkiksi polttoaineiden ja kemikaalien varastoinnissa ja joillakin seuduilla muunlaiset såiliot eivåt ole sallittuja. On myos tunnettua tåyttåå vaippojen vålinen tila etyleeniglykolin ja veden seoksella, joka on 20 paineistettu tai johon on kohdistettu hydrostaattinen paine paisuntasåilidn avulla. Jos sisåvaippa tai ulkovaippa puhkeaa, havaitaan tåmå paineen muutoksena tai nesteen pinnankorkeuden muutoksena paisuntasåiliosså.It is known to use double-shelled tanks, for example for the storage of fuels and chemicals, and in some areas other types of tanks are not permitted. It is also known to fill the space between the jackets with a mixture of ethylene glycol and water which is pressurized or hydrostatically pressurized by means of an expansion tank. If the inner jacket or outer jacket ruptures, this is detected as a change in pressure or a change in the level of the liquid in the expansion tank.
Glykolin kåytto on kuitenkin sinånså haitallista. Ulkovaipan puhjetessa sitå joutuu 25 maaperåån, josta sen poisto on hankalaa. Glykoli on vesiliukoista ja leviåå siksi nopeasti laajalle alueelle, mistå sen poistaminen on hankalaa ja kallista.However, the use of glycol is harmful in itself. When the outer casing breaks out, it gets into 25 soils, from which it is difficult to remove. Glycol is water-soluble and therefore spreads quickly over a wide area, making it difficult and expensive to remove.
Sisåvaipan puhjetessa vettå ja glykolia joutuu varastoitavaan nesteeseen, mikå aiheuttaa såilion sisållon pilaantumisen. Pienikin måårå glykolia esimerkiksi bensiinin, dieseloljyn, 30 kevyen polttooljyn joukossa aiheuttaa vakavia lika-, kåynti- ja karstaongelmia moottoreissa sekå oljypolttimissa. Glykoli-vesiseos aiheuttaa lisaksi såilion vaippojen korroosiota. Korroosion estoon tarpeelliset korroosioinhibiitit lisååvåt edelleen seoksen myrkyllisyyttå.When the inner jacket bursts, water and glycol get into the liquid to be stored, which causes contamination of the contents of the container. Even a small amount of glycol, for example in petrol, diesel, light fuel oil, causes serious dirt, running and scaling problems in engines and oil burners. The glycol-water mixture also causes corrosion of the silo shells. The corrosion inhibitors necessary to prevent corrosion further increase the toxicity of the mixture.
Siten tarvetta esiintyy kaksoisvaipallisille såilioille, joissa kåytettåvållå suojanesteellå ei 91625 2 olisi edellå mainittuja haittoja. Keksinnon mukaisessa såiliosså on ratkaistu edellå mainitut ongelmat.Thus, there is a need for double-shelled silos in which the protective liquid used does not have the above-mentioned disadvantages. The above-mentioned problems have been solved in the container according to the invention.
Keksinto koskee nåinollen sellaista såiliotå ympåristolle haitallisten nesteiden varastoimi-5 seksi, jossa on ainakin osittainen kaksoisvaippa ja jossa vaippojen vålinen tila sisåltåå nestettå. Keksinnon mukainen sailio on tunnettu siitå, ettå vaippojen vålisesså tilassa olevana nesteenå kåytetåån nestettå, jolla on seuraavat ominaisuudet: (a) on ympåristolle haitaton joutuessaan såilion ulkopuolelle; ja 10 (b) on haitaton itse såiliossa pidettåvålle tuotteelle.The invention thus relates to a container for storing liquids which are harmful to the environment, having at least a partial double jacket and in which the space between the jackets contains a liquid. The silo according to the invention is characterized in that a liquid is used as the liquid in the space between the diapers, which has the following properties: (a) is harmless to the environment when it comes outside the silo; and 10 (b) is harmless to the product in the container itself.
Kåytettåvån nesteen on oltava ympåristdlle vaaratonta, jolloin ulkovaipan mahdollisen puhkeamisen johdosta ei synny saastumis- ja håvitysongelmia. Suotavimpia ovat sellaiset 15 nesteet, jotka hajoavat itseståån luonnossa tapahtuvan hajotustoiminnan vaikutuksesta, jolloin erillistå kerååmistå ja tuhoamista ei anakaan pienisså vuodoissa tarvita.The fluid used must be safe for the environment, so that no problems of contamination and destruction arise due to the possible rupture of the outer casing. The most desirable are those liquids which decompose spontaneously as a result of natural decomposition activities, so that separate collection and destruction is not required, even in small spills.
Toinen vaatimus kåytettåvålle nesteelle on se, ettå se ei aiheuta haittoja såilidsså varastoi-tavalle nesteelle, mikåli sisåkuori puhkeaa. Tåmå tarkoittaa sitå, ettå kåytettåvå neste ei 20 kohtuullisen pieninå måårinå haittaa varastoitavan tuotteen kåyttåmistå alkuperåiseen tarkoitukseensa. Esimerkiksi bensiinin tai dieseloljyn tapauksessa tåmå tarkoittaa sitå, ettå kåytettåvå neste ei aiheuta kohtuullisina måårinå ongelmia moottorikåytosså.Another requirement for the liquid used is that it does not cause any harm to the liquid stored in the container if the inner shell ruptures. This means that the liquid used does not, in a reasonably small amount, interfere with the use of the product to be stored for its original purpose. For example, in the case of petrol or diesel, this means that the fluid used does not cause a reasonable amount of problems in engine operation.

Edellåmainitut vaatimukset tåyttåviå nesteitå ovat tietyt biohajoavat nesteet, jotka luonnos-25 sa hajoavat bakteeritoiminnan vaikutuksesta itseståån. Erityisen soveliaita ovat tietyt luonnosta peråisin olevat aineet, kuten erilaiset kasvioljyt ja niiden esterit. Sopivia ovat myos tavalliset alkoholit, kuten metanoli ja etanoli. Myos erååt synteettiset esterit, kuten ‘ voiteluaineena kåytettåvåt biohajoavat esterit ovat sopivia.Liquids that meet the above requirements are certain biodegradable liquids which, by their nature, decompose spontaneously under the influence of bacterial activity. Certain substances of natural origin, such as various vegetable oils and their esters, are particularly suitable. Ordinary alcohols such as methanol and ethanol are also suitable. Some synthetic esters, such as biodegradable esters used as lubricants, are also suitable.
30 Edellåmainitut nesteet eivåt aiheuta myoskåån myrkytys- tai likaamisongelmia såiliosså varastoitavan nesteen kannalta.30 The above liquids also do not cause poisoning or contamination problems for the liquid stored in the container.
Esimerkkejå sopivista nesteistå keksinnon mukaisissa såiliosså kåyttoå vårten ovat sitenExamples of suitable liquids for use in the containers according to the invention are thus
IIII
3 91625 kasvioljyt tai kasvioljyesterit, oljyesterit, alkoholit ja synteettiset biohajoavat voiteluoljyt. Erityisen sopivia ovat mm. rypsi-, rapsi-, soija- tai auringonkukkaoljyt tai niiden esterit sekå måntyoljyesteri.3 91625 Vegetable oils or esters of vegetable oils, petroleum esters, alcohols and synthetic biodegradable lubricating oils. Particularly suitable are e.g. rape, colza, soybean or sunflower oil or their esters, and pine oil ester.
5 Esimerkiksi rypsioljyesterin jåhmepiste on noin -30 °C, mikå on riittavån alhainen arvo maanalaisia såilioitå vårten. Rypsioljyn leimahduspiste on yli 100 °C, joten sen paloluok-ka ei aiheuta ongelmia. Rypsiesterin joutuminen polttoaineen joukkoon ei haittaa, vaan on pikemminkin edullista. Esimerkiksi dieselmoottorin savutus- ja hiukkaspååstot vielåpå alenevat sekoitettaessa rypsioljyesteriå dieseldljyn joukkoon. Rypsioljyesteri ei mydskåån 10 aiheuta korroosio-ongelmia. Ainakin osittain samantapaisia ominaisuuksia on myos muilla edellåluetelluilla nesteillå.5 For example, rapeseed oil ester has a pour point of about -30 ° C, which is a sufficiently low value for underground canning. Rapeseed oil has a flash point above 100 ° C, so its fire class is not a problem. The inclusion of rapeseed ester in the fuel is not detrimental, but rather advantageous. For example, the smoke and particulate emissions of a diesel engine are further reduced by mixing rapeseed oil ester with diesel oil. Rapeseed oil ester mydskåån 10 does not cause corrosion problems. The other liquids listed above also have at least partially similar properties.
Keksinnon mukaisessa såiliosså on ainakin osittainen kaksoisvaippa. Siten kaksoisvaipan ei tarvitse ympårdidå koko såiliotå, vaan såilidsså voi olla yksinkertainen seinåmå niiltå 15 osin, jotka eivåt ole kosketuksessa varastoitavan nesteen kanssa. Siten såilion ylåosa voi olla normaalirakenteinen, mutta alapuolella ja sivuilla seinåmå on kaksinkertainen.The container according to the invention has at least a partial double jacket. Thus, the double jacket does not have to encircle the entire container, but the container may have a simple wall in those parts which are not in contact with the liquid to be stored. Thus, the upper part of the silo may have a normal structure, but the wall below and on the sides is double.
Vuodon toteamiseen voidaan kåyttåå sinånså tunnettuja menetelmiå ja laitteita. Eras tapa vuodon havaitsemiseksi on ylipaineen yllåpitåminen kaksoisseinåmien vålisesså tilassa. 20 Jåijestelmå voi sisåltåå hålytyksen paineen laskiessa seinåmien vålisesså tilassa. Toinen yleisempi tapa on kåyttåå hyvåksi paisuntasåiliotå ja pinta-anturia.Methods and equipment known per se can be used to detect leakage. An Eras way to detect a leak is to maintain an overpressure in the space between the double walls. 20 The system may include an alarm when the pressure drops in the space between the walls. Another more common way is to use an expansion tank and a surface sensor.
Keksinnon mukaista såiliotå voidaan soveltaa sekå maanpåållisenå såilionå ettå maanalaise-na såilionå. Varsinkin maanalaisen såilion tapauksessa keksinnon edut ovat ilmeiset, 25 koska kallis ja suuritdinen maaperån siivoaminen våltetåån eikå såilion alle ja ympårille tarvitse rakentaa kallista vuorausta, esimerkiksi betonikaukaloa.The container according to the invention can be applied both as an above-ground container and as an underground container. Particularly in the case of an underground silo, the advantages of the invention are obvious, since expensive and large-scale soil cleaning is avoided and it is not necessary to build an expensive lining under and around the silo, for example a concrete trough.
Keksinnon mukainen såilio soveltuu kaikenlaisten myrkyllisten ja ympåristolle haitallisten nesteiden varastointiin. Tållaisia nesteitå ovat muun muassa polttoaineet, ku ten bensiini, 30 dieseloljy ja polttooljy, liuottimet, voiteluoljyt ja muut myrkylliset kemikaalit.The container according to the invention is suitable for the storage of all kinds of toxic and environmentally harmful liquids. Such fluids include fuels such as gasoline, diesel and fuel oil, solvents, lubricating oils, and other toxic chemicals.
