摘要:
The invention relates to the industrial field of gas storage systems, and concerns a pneumatic membrane gasometer (1 ) for the storage of hydrogen gas at low pressure, comprising: - a first bag-shaped membrane (10) adapted to delimit a hydrogen storage chamber (C1 ); - a second membrane (20) adapted to partially delimit a pressurization chamber (C2) superimposed, at least in part, on said storage chamber (C1 ); - a third membrane (30), placed resting on top of said first membrane (10), fixed in an impermeable manner at least to said second membrane (20), adapted to define, with said first membrane (10), a cavity (2) open towards the outside of the gasometer (1 ); - hydrogen supply and discharge means associated with said storage chamber (C1 ); - pressurization means of said pressurization chamber (C2) by means of air; - mechanical anchoring means (4) to a base surface (S) of said first (1 ), second (20) and third (30) membranes; - a natural passive ventilation system to vent any hydrogen losses to the outside, comprising a duct (5) adapted to connect cavity (2) to the outside environment passing through said pressurization chamber (C2).

A system for storing air at high pressure underground or underwater includes a plurality of arrays of air tanks, each tank configured to store compressed air at a pressure of at least 40 bar. A piping system connects between an outlet of each air tank, the piping system further including at least one central port for delivering compressed air to and from a respective array. A storage receptacle surrounds the arrays and piping system, protecting the arrays and piping system from an external environment, and thermally insulating the arrays and piping system. A liquid bath is arranged within the storage receptacle. A heat exchanger is configured to maintain a temperature of the liquid bath substantially constant. The storage receptacle may be comprised of plastic pieces welded together in a modular fashion. Each piece may be a cylindrical tube configured to receive therein one or more of the arrays.

Die Erfindung betrifft eine Vorrichtung zur gasdichten Abdeckung von Lagerbehältern ohne Innenstütze und bestehent aus einer einfachen oder zweifachen flexiblen Membrane, wobei die eingesetzten Membranen (1.1, 1.2) etwa im Bereich der Behälterachse (3) gegen horizontale Verschiebungen fixiert sind; die den mittleren Bereich der Abdeckmembranen (1.1, 1.2) fixierenden Haltekonstruktionen (5) oberhalb der Abdeckmembranen (1.1, 1.2) angeordnet sind; die Lage der mittlere Verankerung (4) der Abdeckmembranen (1.1, 1.2) wenigstens zu zwei Verankerungspunkten (6) gesichert ist; die Stützelemente (7) für die Haltekonstruktionen (5) außerhalb des abzudeckenden Lagerbehälters angeordnet sind; im Falle des Einsatzes einer zweischaligen Abdeckmembran (1.1, 1.2) die Membranen außer an der Behälterwand (2) des abzudeckenden Lagerbehälters auch im Bereich der Behälterachse (3) miteinander verbunden sind; das Verbindungselement (10) für die beiden Abdeckmembranen (1.1, 1.2) im Bereich der Behälterachse (3) ein flexibles Zugelement (11) ist und im Bereich zwischen dem zu lagernden Medium und der unteren Abdeckmembran (1.2) ein Ballastelement (12) angeordnet ist.
摘要:
A proppant storage vessel (10) has a first container (1.2) with an interior volume (14), and a second container (16) supported in spaced relation above the first container. The first container (12) has a bottom hatch (22) affixed to a bottom wall (20) thereof. The bottom hatch (22) is movable between an open position and a closed position. The first container (12) has m opening at a top wall thereof. The second container (16) has bottom hatch (28) formed on a 'bottom wail thereof. The bottom hatch (28) of the second container (16) is aligned with the opening of the first container (12) such that a proppant in the second container can flow through the hatch thereof into the interior volume (14) of the first container. Each of the containers includes first, second, third and fourth inclined surfaces positioned m the interior volume and extending from the respective side walls and end wails thereof toward the bottom hatch.

The invention relates to a spherical object (100) formed of several joint parts (1). The parts (1) of the spherical object comprise at least twenty pieces of hexagonal panel-type elements (1) and at least twelve pieces of pentagonal panel-type elements (1). The radius of curvature of each panel-type element (1) is formed to be such that when joined together, they form a hollow spherical object (100), the radius of curvature of which is at least 0.75 metres. The panel-type elements (1) are provided with an attachment and handling cap (10). Around the spherical object (100) are fixed first vacuum components (110, 110a) that form an inner vacuum layer (110'), and second vacuum components (120, 120a) that form an outer vacuum layer (120'), which is at a distance from the inner vacuum layer (110') in the radial direction of the spherical object (100). Between the inner vacuum layer (110') and outer vacuum layer (120') are arranged intermediate components (5) which form an intermediate layer (5'). The vacuum components (110, 110a, 120, 120a) and intermediate components (5) comprise fixing means (200) by means of which the vacuum components (110, 110a, 120, 120a) and the intermediate components (5) can be fixed in place to the attachment and handling caps (10).
