Abstract
Očelom riešenia je vyčerpáme cisterny kvapalného plynu pod tlakom vyšším, než je tlak nasýtených pár kvapalného plynu při danej teplote. Účel sa dosiahne využitím expanzie pár kvapalného plynu z inej, teplej cisterny, v ktorej tlak plynu dosahuje požadovaná hodnotu, takým sposobom, že parné priestory oboch cisterien sa navzájom prepoja vyrovnávacím potrubím s vyrovnávacím ventilom.The purpose of the solution is to exhaust the liquid gas tanks under a pressure higher than the saturated vapor pressure of the liquid gas at a given temperature. The purpose is achieved by utilizing the expansion of the liquid gas vapor from another, warm tank, in which the gas pressure reaches the required value, in such a way that the vapor spaces of both tanks are interconnected by an equalization pipe with an equalization valve.
Description
Vynález sa týífa/prepojenia cisterierv na , ,,ι kvapalné plyny, kqe každ& cj^^iaj^e ýpM |j třená výtlačným potrubím a uzatváracím ventilom a v parnom priestor©· je’ umlesteue·*· ná spádová trúbka, ktorej druhý koniec je opatřený odplyňovacím ventilom.The invention relates to / interconnection of cisterierves to, and / or liquid gases, each amp; with a discharge pipe and a shut-off valve and in the steam chamber there is a downcomer, the other end of which is provided with a degassing valve.
Tlakové vyčerpáváme zásobníkov skvapalnených plynov je založené na termickej expanzii. Potřebné teplo sa dodává zvonku, ofukovaním cisterny teplým vzduchom, alebo jej sprchováním teplou vodou. Zásohovanie chemickej výroby je organizované tak, že pojazdná cisterna sa dopraví do uzavretej kobky, kde sa vyššie uvedeným sposobom temperuje, kým tlak nasýtených pár vo vnútri cisterny nedosiahne požadovanú hodnotu, dostatočnú na to, aby kvapalná fáza bola týmto tlakorn z cisterny vyčerpaná do sústavy. Dve, alebo viac susedných kobiek může takto vytemperovať dve, alebo viac pojazdných cisterien odrazu. Tento sposob je energeticky náročný a ipomalý.Pressure depletion of liquefied gas tanks is based on thermal expansion. The necessary heat is supplied from the outside by blowing the tank with warm air or by spraying it with warm water. The stacking of the chemical production is organized in such a way that the mobile tank is transported to a closed cell where it is tempered by the above-mentioned method, while the pressure of the saturated vapor inside the tank does not reach the desired value sufficient for the liquid phase to be pressurized from the tank to the system. Two or more adjacent cells can thus equilibrate two or more mobile reflection tanks. This method is energy intensive and slow.
Energeticky menej náročný je sposob, spočívajúci v recirkulácii obsahu cisterny cez výparník. Jeho nevýhoda však spočívá v nárokoch na presnú reguláciu, pretože dynamika vyparovania kvapalných plynov sa vyznačuje búrlivým priebehom, ak nie sú dodržané optimálně podmienky přestupu tepla.A less energy-intensive method is the recirculation of the tank contents through the evaporator. However, its disadvantage lies in the need for precise control, since the vaporization dynamics of liquid gases are characterized by a turbulent course if the heat transfer conditions are not optimally maintained.
Uvedené nedostatky sú odstránené pre- . pojením cisterien na kvapalné plyny podfa vynálezu, ktorého podstata spočívá v tom, že prvý odplyňovací ventil teplej cisterny je spojený s druhým odplyňovacím ventilom najmenej jednej studenej cisterny pomocou vyrovnáwacieho potrubia s vyrovnávacím ventilom. Přepojením cisterien na kvapalné plyny podfa vynálezu sa dosiahne to, že tlakorn pár teplej cisterny sa može vyčerpávat ob- h sah studmjefe ástežirv,kalého -ohidve cisterI ny VarazL&íiw satíU^TErrenergia na vyhriatie studenej cisterny. Dalšia výhoda prepojenia > -teplfej-a <stádenej cisterny spočívá v tom, že sa zvýši pohotovostná kapacita zásobovania, pretože sa nemusí čakať na zdíhavé ohrievanie cisterien. (Příklad prepojenia cisterien podfa vynálezu je zobrazený na priloženom výkrese.These shortcomings are eliminated. The invention relates to the connection of liquid gas tanks according to the invention, wherein the first degassing valve of the hot tank is connected to the second degassing valve of at least one cold tank by means of an equalizing valve. By transferring the liquid gas tanks according to the invention, it is achieved that the pressure tank of the hot tank can be depleted of the volume of the cold storage tank to heat the cold tank. A further advantage of the interconnection of the " warm " tank is that the standby capacity of the supply is increased because it does not have to wait for the heating of the tanks. (An example of interconnection of tanks according to the invention is shown in the attached drawing.
Teplá cisterna 1 je vo svojej spodnej časti opatřená výtlačným potrubím s uzatváracím ventilom 11 a taktiež studená cisterna 2 je vo svejej spodnej časti opatřená výlačným potrubím 9 s uzatváracím ventilom 12. V parnom priestore teplej cisterny 1 aj studenej cisterny 2 je umiestnená spádová trúbka 3. Na vonkajšom konci spádovej trubky 3 teplej cisterny 1 je umiestnený prvý odplyňovací ventil 5 a na vonkajšom konci spádovej trúbky 3 studenej cisteny 2 je umiestnený druhý odplyňovací ventil G. Prvý odplyňovací ventil 5 teplej cisterny 1 a druhý odplyňovací ventil 6 najmenej jednej studenej cisterny 2 je přepojený vyrovnávacím potrubím 10 s vyrovnávacím ventilom 7.In its lower part, the hot tank 1 is provided with a discharge pipe with a shut-off valve 11 and also a cold tank 2 is provided in its lower part with a discharge pipe 9 with a shut-off valve 12. In the steam chamber of both the hot tank 1 and the cold tank 2 there is a gravity pipe 3. A first degassing valve 5 is provided at the outer end of the downcomer 3 of the hot tank 1 and a second degassing valve G is located at the outer end of the downcomer 3 of the cold purge 2. The first degassing valve 5 of the hot tank 1 and the second degassing valve 6 of at least one cold tank 2 are coupled with equalization line 10 with balancing valve 7.
Funkcia prepojenia sa prejaví tak, že po otvorení odplyňovacieho ventilu 5, vyrovnávacieho ventilu 7 a odplyňovacieho ventilu 6 najmenej jednej studenej cisterny 2, začnú páry z parného priestoru teplej cisterny 1 prenikať do parného priestoru najmenej jednej studenej cisterny 2 a vytláčať kvapalnú fázu z najmenej jednej studenej cisterny 2 pod tlakorn nasýtených pár kvapalného plynu zodpovedajúcim teplote v teplej cisterně 1, cez výtlačné potrubie 9 a uzatvárací ventil 11 na ďalšie spracovanie.The interconnection function is manifested by opening the degassing valve 5, the balancing valve 7 and the degassing valve 6 of at least one cold tank 2, the steam from the hot tank steam space 1 penetrates into the vapor space of at least one cold tank 2 and displaces the liquid phase from at least one the cold tank 2 under the pressure-saturated vapor of the liquid gas corresponding to the temperature in the hot tank 1, through the discharge pipe 9 and the shut-off valve 11 for further processing.
Vynález možno využiť u přečerpávacích stanic spracovávajúcich najmenej dve cisterny kvapalných plynov.The invention can be applied to lifting stations processing at least two liquid gas tanks.
