Abstract
Description
511 146 2 Den delade formen innebär expansionsmöjligheter vid fasväxlingen. 511 146 2 The divided form means expansion possibilities at the phase shift.
Vid ett föredraget alternativ anordnas kring flänsarna i det flänsförsedda röret ett perforerat band, vilket tillsammans med det flänsförsedda röret placeras i den mot salt tätande päsen, vilket band är anordnat att uttaga tryck fràn kristalltillväxt vid fasväxling flytande -fast.In a preferred alternative, arrangements are made around the flanges in the flanged tube a perforated band, which together with the flanged pipe is placed in it against salt sealing peg, which band is arranged to take off pressure from crystal growth during phase change liquid -solid.
Vid ett ytterligare utföringsalternativ användes formar av polystyren, och den använda pàsen kan lämpligen bestå av polyeten, tät för salt i smält form. Bandet, som lindats kring det flänsförsedda röret kan lämpligen vara perforerat till cirka 50 % för fyllning av salt i smält form och för att åstadkomma diffusion till och fràn salt, dehydrerat eller hydrerat.In a further embodiment, molds of polystyrene, and the bag used may suitably consist of polyethylene, tight for salt in molten form. The band, which is wrapped around the flanged tube may conveniently be perforated to about 50% for filling salt in molten form and for cause diffusion to and from salt, dehydrated or hydrated.
Detta band upptager tryck fràn kristalltillväxt vid fasväxling flytande - fast och kan tillàta viss expansion.This band absorbs pressure from crystal growth at phase shift fluid - solid and may allow some expansion.
Saltet i de färdiga stavarna kan vid användning exempelvis uttorkas med solfångare under den varma àrstiden, och sedan kan värmen uttagas pá vintern genom att vattnet fàr àtergà till saltet. Man kan även utnyttja spillvärme fràn industrien för torkningen = värmeupplagringen.The salt in the finished rods can be used, for example dried with solar panels during the hot season, and then the heat can be removed in the winter by allowing the water to return to the salt. You can also use waste heat from industry for drying = heat storage.
Allt det metalliska materialet, som användes vid metoden, bör vara stàl.All the metallic material used in the method should be steel.
Efter torkningen, som sker medelst transport/genomflöde av hett vatten, sker förpackning av de erhållna stavarna i en tank, vilket underlättar deras följande användning, där de sammanbygges med flera tankar/energidimensionerat antal. ß 511 146 Ritning: Uppfinningen är exemplifierad i bifogad ritning.After drying, which takes place by means of transport / flow of hot water, packaging of the obtained rods takes place in a tank, which facilitates their subsequent use, where they combined with several tanks / energy-dimensioned number. ß 511 146 Drawing: The invention is exemplified in the accompanying drawing.
Utföringsexempel: Kring ett med konvektorflänsar (4) försett konvektorrör (1) placeras ett band (6), vilket är perforerat till cirka 50 %.Exemplary embodiments: Convector tubes (1) fitted with convector flanges (4) a band (6) is placed, which is perforated to about 50%.
Detta band tillàter viss expansion vid kristallväxten i saltet vid fasövergangen. Det är avsett för fyllning av salt i smält form och för att åstadkomma diffusion till och frán saltet, dehydrerat eller hydrerat. Upptill är anordnad en pàfyllningstratt (7) av plast. Kring det flänsförsedda röret med dess omgivande band anordnas en pàse av polyeten, tät för salt i smält form (3). Denna är nertill tätad mot röret vid (2). Den sà erhàllna kroppen placeras i en delad form (5) av polystyren, vilken tillåter expansion av gjutkroppen vid fasväxling till fast form för saltet (natriumsulfid).This band allows some expansion at the crystal growth in the salt at the phase transition. It is intended for filling with salt in molten form and to effect diffusion to and from the salt, dehydrated or hydrated. At the top is arranged one plastic filling funnel (7). Around the flanged pipe with its surrounding band a polyethylene bag is arranged, tight for salt in molten form (3). This is sealed at the bottom against the pipe at (2). The body thus obtained is placed in a divided shape (5) of polystyrene, which allows expansion of the casting body at phase change to solid form of the salt (sodium sulphide).
I det av pàsen tillslutna utrymmet ifylles vid (7) salt i smält form och vid den efterföljande fasväxlingen tillàter formen (5) och även bandet (6) expansion.In the space enclosed by the bag, fill with (7) salt in molten form and at the subsequent phase change allows the mold (5) and also the band (6) expansion.
Temperaturen för det smälta saltet kan vid ifyllandet vara +40/50 grader och fasväxlingen kan ske i rumstemperatur +20 grader under viss tid.The temperature of the molten salt may be at the time of filling +40/50 degrees and the phase change can take place at room temperature +20 degrees for some time.
Uppfinningen kan varieras pá màngahanda sätt inom ramen för nedanstående patentkrav.The invention can be varied in many ways within the scope for the following claims.
