Description
Denne oppfinnelsen gjelder en anvendelse av kaliumformiat og fremgangsmåte for å oppløse eller fjerne tåke og/eller skyer på en miljøvennlig måte og som er spesielt egnet for tåke og skyer som har en temperatur på over -2°C, eller såkalt «varm tåke». This invention relates to an application of potassium formate and a method for dissolving or removing fog and/or clouds in an environmentally friendly way and which is particularly suitable for fog and clouds that have a temperature above -2°C, or so-called "warm fog".
Tåke utgjør et tildels stort problem for en rekke aktiviteter. Som eksempel kan nevnes forskjellige former for samferdsel og forskjellige utendørsaktiviteter som idrettsstevner og lignende. Spesielt er tåke et stort problem for flytrafikken. Når flyplasser må stenges på grunn av tåke medfører dette betydelige kostnader og forsinkelser for passasjerene. Dessuten utgjør den reduserte sikten en betydelig økt ulykkesrisiko for all samferdsel, ikke bare for flytrafikken. Fog poses a relatively large problem for a number of activities. Examples include different forms of transport and different outdoor activities such as sports events and the like. Fog in particular is a major problem for air traffic. When airports have to be closed due to fog, this entails significant costs and delays for passengers. Furthermore, the reduced visibility poses a significantly increased accident risk for all traffic, not just for air traffic.
Det er vel kjent å fjerne tåke fra f.eks flyplasser ved at et luftfartøy, rakett eller kanon sprer et tåkeoppløsende materiale slik at vannpartiklene i tåken fortettes og faller ned som nedbør. Det er i litteraturen beskrevet en rekke forskjellige egnede stoffer som når de spres over et område vil øke presipiteringen av tåkens/skyenes vannpartikler, så som forskjellige bromider, iodider, sulfater, nitrater, klorater og perklorater av alkaliske metaller samt Agl og AgBr, se for eksempel NO 125 989, US 3 613 992 og DE 3 228 755. Felles for disse forbindelsene er at de er giftige og har dermed uønskede og skadelige effekter på miljøet som blir eksponert for dem. Dette kan utgjøre et betydelig problem for områder som har behov for hyppig fjerning av tåke. Sølvforbindelsene er dessuten svært kostbare, og sulfatene og nitratene gir forsuring av nedbøren. It is well known to remove fog from e.g. airports by an aircraft, rocket or cannon spreading a fog-dissolving material so that the water particles in the fog condense and fall as precipitation. A number of different suitable substances are described in the literature which, when spread over an area, will increase the precipitation of fog/cloud water particles, such as various bromides, iodides, sulphates, nitrates, chlorates and perchlorates of alkaline metals as well as Agl and AgBr, see for for example NO 125 989, US 3 613 992 and DE 3 228 755. What these compounds have in common is that they are toxic and thus have unwanted and harmful effects on the environment that is exposed to them. This can pose a significant problem for areas that need frequent fog removal. The silver compounds are also very expensive, and the sulphates and nitrates acidify the precipitation.
Søkeren har i norsk patent no. 176 727 beskrevet anvendelsen av tørris til å fjerne tåke. Dette er et miljøvennlig stoff, men er belemret med den ulempen at det kun virker effektivt på tåke/skyer som er kaldere enn -2°C. Fra EP 0 611 388 er det kjent at en kaliumformiatløsning i dråpeform virker hygroskopisk og kan absorbere vanndamp i kjølesystemer. The applicant has in Norwegian patent no. 176 727 described the use of dry ice to remove fog. This is an environmentally friendly substance, but is burdened with the disadvantage that it only works effectively on fog/clouds that are colder than -2°C. From EP 0 611 388 it is known that a potassium formate solution in droplet form is hygroscopic and can absorb water vapor in cooling systems.
Det er en målsetning med foreliggende oppfinnelse å tilveiebringe en fremgangsmåte for å oppløse eller fjerne tåke og/eller skyer som er varmere enn -2°C på en miljøvennlig måte, og som ikke gir noen skadevirkninger på dyre og plantelivet i området som utsettes for fremgangsmåten. It is an objective of the present invention to provide a method for dissolving or removing fog and/or clouds that are warmer than -2°C in an environmentally friendly way, and which does not cause any harmful effects on animal and plant life in the area exposed to the method .
Hensikten med oppfinnelsen oppnås ved at tåken/skyene som skal fjernes blir påstrødd kaliumformiat i pulverform. Etter flere års utprøving av forskjellige harmløse stoffer, er det funnet at kaliumformiat er spesielt egnet for å øke presipiteringen av vannpartikler ved temperaturer over -2°C, spesielt i området +2 til +4°C. Alternativt kan en blokk av presset kaliumformiat anbringes like over området som skal behandles og sprenges slik at kaliumformiatet pulveriseres og spres utover. The purpose of the invention is achieved by the fog/clouds to be removed being sprinkled with potassium formate in powder form. After several years of testing various harmless substances, it has been found that potassium formate is particularly suitable for increasing the precipitation of water particles at temperatures above -2°C, especially in the range +2 to +4°C. Alternatively, a block of pressed potassium formate can be placed just above the area to be treated and blasted so that the potassium formate is pulverized and spread outwards.
Det er beskrevet en rekke metoder for å bringe det tåkeoppløsende stoffet fram til tåken. Foreliggende oppfinnelse benytter kjent teknikk for å anbringe kaliumformiatet, slik at dette vil ikke bli omtalt nærmere. Det vises til anvendelse av et luftfartøy/fly eller til kanon slik som beskrevet i norsk patent no. 176 727. A number of methods have been described for bringing the fog-dissolving substance to the fog. The present invention uses known techniques to place the potassium formate, so that this will not be discussed in more detail. It refers to the use of an aircraft/plane or to a cannon as described in Norwegian patent no. 176,727.
