Description

Oppfinnelsen angår et vanndistribusjonssystem som især er tilpasset for jevn fordeling av vann til et antall oppad åpne vannbeholdere. Vannet tilføres et rørsystem som er plassert over beholderne og ledes fra rørsystemet til beholderne gjennom fallrør som munner ut under, vannflaten i beholderne. Disse fallrør kan være utstyrt med vannfordelere som gir en rolig, uforstyrret utstrømning av vannet. I en foretrukket utforming utgjøres vannfordelerne av de åpne beholdere og inn-går i fordampningsmoduler i et varmepumpeanlegg som henter fordampningsvarmen fra sjøvann. Gjennom åpninger i beholder-nes bunn, strømmer vann over et antall under beholderne plas-serte fordampningsmoduler. Ved siden av jevn, uforstyrret fordeling av vannet til beholderne, innebærer den hevertvirkning som oppstår i fallrørene en energigjenvinning som bidrar til å minske det nødvendige pumpearbeide ved transport av sjø-vann . The invention relates to a water distribution system which is especially adapted for the even distribution of water to a number of water containers open upwards. The water is supplied to a pipe system that is placed above the containers and is led from the pipe system to the containers through downpipes that open below the water surface in the containers. These downpipes can be equipped with water distributors that provide a calm, undisturbed outflow of the water. In a preferred design, the water distributors are made up of the open containers and form part of evaporation modules in a heat pump system which obtains the evaporation heat from seawater. Through openings in the bottom of the containers, water flows over a number of evaporation modules placed under the containers. Alongside the even, undisturbed distribution of the water to the containers, the siphoning effect that occurs in the downpipes involves energy recovery which helps to reduce the necessary pumping work when transporting seawater.

Gjennom nevnte hevertvirkning i fallrørene, oppnås et undertrykk i fordelingsrørsystemet som medfører at luft opp-tatt i vannet frigjøres. Denne luft samles opp og danner luft-puter i rørsystemet. Luftputene forstyrrer strømning og kan gi opphav til ujevn fordeling av vann til beholderne i anlegget. Through the aforementioned siphoning effect in the downpipes, a negative pressure is achieved in the distribution pipe system, which causes air taken up in the water to be released. This air is collected and forms air cushions in the pipe system. The air cushions disrupt flow and can give rise to uneven distribution of water to the containers in the system.

Ifølgeoppfinnelsen elimineres risikoen for oppsamling av luft i rørsystemet ved at anlegget utstyres med en sugepumpe, som er tilkoblet rørsystemet ved dets høyeste punkt og derfra kontinuerlig suger ut eventuelt frigjort luft. Sugepumpen som kan være av ejektor-typen, er via en drivvannledning tilsluttet en tilførselsledning som forsyner anlegget med vann. Noen separat maskinell drivenhet behøves da ikke for sugepumpen, hvilket forenkler anlegget og gir meget god driftssikkerhet og enkel overvåkning. For at tilstrekkelig drivkraft skal garanteres, må pumpen plasseres under vannivået i beholderne. Drivvannledningen bør også være tilkoblet til-førselsvannledningen under vannivået i de åpne beholdere. According to the invention, the risk of air collecting in the pipe system is eliminated by equipping the plant with a suction pump, which is connected to the pipe system at its highest point and continuously sucks out any released air from there. The suction pump, which can be of the ejector type, is connected via a drive water line to a supply line that supplies the system with water. A separate mechanical drive unit is then not needed for the suction pump, which simplifies the system and provides very good operational reliability and easy monitoring. In order for sufficient driving force to be guaranteed, the pump must be placed below the water level in the containers. The drive water line should also be connected to the supply water line below the water level in the open containers.

Oppfinnelsen beskrives nærmere under henvisning til tegningen hvor figuren viser fordampermoduler 1 i et varmepumpeanlegg som tar varme fra sjøvann som tilføres anlegget gjennom en mateledning 2. Vannets strømningsretning angis med pilen 3. Hver modul 1 inneholder en vannfordeler i form av en oventil åpen beholder 4 med perforert bunn 5 som for-deler vann på fordamperpaneler 6. Hver modul kan ha hver sin oppsamlingsbeholder for vann fra panelene 6, eller anlegget kan ha en felles oppsamlingsbeholder 1 for en gruppemodul 1 eller for samtlige moduler 1, som vist på figuren. Vannivået angis med triangelen 8. Ledningen 2 forsyner et rørsystem 9. Vannet fordeles til beholderne 4 gjennom et fallrør 10 med fordelingsmunnstykker 11 med åpninger som munner ut under vannflaten 11 i beholderne 4. Ved at rørsystemet 9 for fordeling av vann til beholderne 4 ligger ovenfor beholderne og er koplet til disse med fallrør 10 med munnstykker 11, oppstår undertrykk i rørsystemet 9. Munnstykkene 11 munner ut under vannflaten 12 i beholderne.4 for å unngå forstyrrelser av vannfordelingen, og dermed minske pumpearbeidet til panelene 6. Under trykket i rørsystemet 9 kan luft frigjøres fra vannet. Luftbobler forstyrrer vannfordelingen og den hevertvirkning som finnes på grunn av fallrøret 10. Frigjort luft suges bort kontinuerlig gjennom en vanndrevet luftpumpe 13 som via en sugeledning 14 er tilkoblet rørsystemet 9 ved dets høyeste punkt. Ved et omfattende rørsystem 9 kan flere sugeledninger 14 og også pumper 13 være nødvendig. Pumpen 13 er av ejektor-typen og drives av drivvann gjennom en ledning 15. Pumpen 13 og tilkoblingen av drivvannledningen 15 til tilførselslednin-gen 2 er plassert på et nivå under vannflaten 12 i beholderne 4. Sugepumpen plasseres på et slikt nivå at den kan bortføre frigjort luft med tilstrekkelig sugekraft. The invention is described in more detail with reference to the drawing, where the figure shows evaporator modules 1 in a heat pump system that takes heat from seawater that is supplied to the system through a feed line 2. The direction of the water's flow is indicated by the arrow 3. Each module 1 contains a water distributor in the form of a top-open container 4 with perforated bottom 5 which distributes water on evaporator panels 6. Each module can have its own collection container for water from the panels 6, or the facility can have a common collection container 1 for a group module 1 or for all modules 1, as shown in the figure. The water level is indicated by the triangle 8. The line 2 supplies a piping system 9. The water is distributed to the containers 4 through a downpipe 10 with distribution nozzles 11 with openings that open below the water surface 11 in the containers 4. By the piping system 9 for distributing water to the containers 4 located above the containers and are connected to these by downpipes 10 with nozzles 11, negative pressure occurs in the pipe system 9. The nozzles 11 open below the water surface 12 in the containers.4 to avoid disturbances in the water distribution, and thus reduce the pumping work of the panels 6. Under the pressure in the pipe system 9 air can be released from the water. Air bubbles disrupt the water distribution and the siphoning effect that exists due to the downpipe 10. Released air is sucked away continuously through a water-driven air pump 13 which is connected via a suction line 14 to the pipe system 9 at its highest point. In the case of an extensive pipe system 9, several suction lines 14 and also pumps 13 may be necessary. The pump 13 is of the ejector type and is driven by drive water through a line 15. The pump 13 and the connection of the drive water line 15 to the supply line 2 are placed at a level below the water surface 12 in the containers 4. The suction pump is placed at such a level that it can remove released air with sufficient suction power.
