Technical Field

The invention relates to the technical field of high-pressure gas cylinders, in particular to a high-pressure gas cylinder structure for gas storage.

Background

A high pressure bottle is a bottle made of an alloy that can withstand very high atmospheric pressures. The high-pressure bottle is used for storing combustion-supporting gas oxygen, can also be used for storing fuel gas, welding, rockets and the like, and the high-pressure container is used for storing and conveying gas under daily conditions or used as a using tool for compressing gas in transportation to provide power for an internal combustion engine, a fuel cell and aerospace technology.

Conventional high pressure gas cylinders employ a cylinder design in its cylindrical portion that generates high pressure electricity in the circumferential direction, the inner protective metal shell does not bear axial loads, and the cylinder design is not suitable for storing gas under high pressure and cyclic loads up to a thousand or more-the inner protective metal shell is a multi-layer load-bearing frame made of intersecting unidirectional threads and polymer binder, resulting in delamination between them and premature failure of the layers.

High-pressure cylinders made of composite material are known, comprising a metal sheath wound on a protective metal casing with radial corrugations impregnated with unidirectional intersecting lines of a polymeric binder, forming a layer of a force frame, which is heat-treated and selected in view of the temperature ranges of curing the binder and curing the binder at an excessive pressure of the working medium (california, macarov. wendt "glass fibers, moskoco, chemistry, 1986, page 218-. This device has the above-mentioned disadvantages.

One set of important features closest to the present invention is a pressure cylinder made of composite material, comprising a multi-layered power frame, consisting of intersecting unidirectional threads and a polymeric binder, and an inner protective polymeric casing (WO 92/20954 a1, F17C 1/16, 26.10.1992). The disadvantage of this cylinder is its extremely complex design and its great weight. Furthermore, although the known cylinder provides some measure to protect its integrity on the outside, in fact it does not have means to prevent the effect of the internal pressure increase on the cylinder seal, the internal design of the cylinder being such that the pressure increase does not preclude the separation of the internal sealing shell from the force frame, thus breaking the cylinder seal, and to this end a high pressure gas cylinder structure for gas storage is proposed to solve the above mentioned problems.

Specifically, the multilayer power frame 1 is formed by a wind capillary tube on the inner air-proof shell 2.

Specifically, the first sealing system is formed by connecting a metal tube with a capillary tube, and the second sealing system connects the inner airtight shell to the gas supply and release.

Specifically, the open end part 9 of the capillary is inserted into the gas-proof shell 2 in the cylinder, the first pipeline node 5 is connected with a node of the pipeline, gas is supplied and released from the capillary to a consumer, and the second pipeline node 8 is connected with a node of the pipeline, and gas is supplied and released from the inner shell to the consumer.

Specifically, the gas supply and discharge means is installed at one end of the cylinder, and even the cylinder supplies and discharges the gas at both sides of the cylinder in two ways, and the capillary open end portion 9 is guided to the inside of the inner gas-proof housing 2.

Specifically, a power supply element 10 is installed inside the inner gas-proof shell 2, one end of the power supply element 10 is connected with the second collector 7, and the other end of the power supply element 10 is connected to the inner wall of the inner gas-proof shell 2.

The open end 9 of the capillary is made of glass, basalt, quartz, polymer compounds and other materials, the capillary is wetted in a special adhesive, can be used for polymer resins, adhesive compositions, silicates and other compositions, the inner gas-tight envelope 2 is inserted before the open end of the capillary is wound, the access site is sealed, the second end of the capillary is sealed, or the inner gas-tight envelope 2 can be injected, and the balloon is dried (or heated) until the adhesive hardens.

The inner gas-tight casing 2 is a gas-tight casing on which high-strength capillaries (strength at least 1.0GPA) are formed, bonded by polymer resin or adhesive, or composed of silicate and other adhesive forms, to form a multi-layered power frame 1, the gas in the gas cylinder is stored in both the gas-tight casing 2 and the capillaries of the multi-layered power frame 1, and the gas supply and release means, which can be filled and extracted individually and in combination into the casing and the capillaries.

In the first case (fig. 1 and 2), gas is fed and extracted from the inner gas-tight housing 2 through the gas feed and discharge collector two 7 and from the capillary through the gas discharge and discharge collector one 4, while in the inner gas-tight housing 2 and the capillary different gases or the same gas can be stored, the gas pressure in the inner gas-tight housing 2 and the capillary possibly being different.

The gas from the inner gas-tight casing 2 is supplied and released to the gas through the sealing system and connected to the inner second sealing system 6, the inner second sealing system 6 being connected to the inner gas-tight casing 2, if the gas supply and output facilities are located on both sides of the cylinder, they are connected by the power supply element 10, the need for the power supply element 10 is associated with high pressure gas forces affecting the second sealing system 6 and the second collector 7, which may not be able to withstand such loads, and therefore, at a gas pressure of 1000atm, the force on the system is 6.7, the diameter is 5 mm, equal to 196 kg, 392 kg at 2000atm, respectively, the power element is made of high-strength metal material, polymer, silicon dioxide (strength limit is at least 300MP), in the form of perforated tubes, rods, bars, wires and other types of compounds that provide a means for the ingress of gas from the inner housing to supply and release gas from the gas-tight housing 7.

With the help of the sealing and connection system of the first sealing system 3, which seals and connects the capillary tube to the metal tube, the gas discharged from the open end of the wind capillary tube is sent to the means for supplying and releasing gas from the capillary collector one 4, and then the gas is supplied and released from the capillary tube to the consumer through the joint of the connecting pipe.

In the second case (fig. 3 and 4), the open end 9 of the capillary is inserted into the inner shell of the cylinder, the volumes of the inner shell and of the capillary are combined, connected to the capillary by a duct to the collector two 8, the gas and the extracted gas in the shell and in the capillary are refueled and discharged.

To form a multi-layer power frame, capillaries made of glass, basalt, quartz, polymer compounds and other materials are supplied and released from the inner air-tight sheath 2 with the second sealing system 6 and power elements using a sealing system, while the capillaries are wetted in a special adhesive for polymer resins, adhesive compositions, silicates and other compositions, inserted into the inner air-tight sheath 2 before the open end of the capillaries 9 are wound, the entry site is sealed, the second end of the capillaries is sealed, or the inner air-tight sheath can be injected, and the balloon is dried (or heated) until the adhesive hardens.

Such cylinders are fundamentally different from prototypes in which the gas is contained only in the internal gas-sea shell, and in order to increase the gas content, the pressure of the gas needs to be increased, which requires the thickness of the multi-layer power frame to be increased, thereby increasing the weight of the gas cylinder. For example, in such cylinders, the mass content of the gas (hydrogen) is 2-5% by mass (percentage ratio of the weight of the gas to the weight of the cylinder).

In the proposed version of the cylinder, the gas is contained in the inner shell and capillary tubes, and unlike the prototype, a similar increase in force frame thickness increases the pressure of the gas in the inner shell, resulting in an increase in capillary tubes in the power frame, increasing the volume of the gas and capillary tubes, and therefore, in this case, not only increasing the weight of the cylinder as in the prototype, but also increasing the volume of the gas in the capillary tubes.

Another advantage of the proposed cylinder compared to the prototype is that the ratio of the volumes of the inner shell and the capillary tube may vary, thus the thickness of the force frame and the diameter of the inner shell, allowing high pressure gas to be provided in the cylinder (unacceptable in the prototype), and thus varying in its content.

Example (c): let us compare the characteristics of a prototype bomb made of composite material and equipped with a capillary tube with a diameter of 100 microns. The outer sizes of the gas cylinders are the same, the diameter of the inner shell of the prototype machine is 300 mm, and the hydrogen pressure in the gas cylinder is 4000 ten thousand pixels, and the tensile stress level is 550 MPA.

Under 100MPA pressure, the tensile stress level is the same, the diameter of the proposed gas cylinder inner shell is 260mm, and the comparative characteristics of the gas cylinder are shown in the following table:

to sum up, this a high-pressure gas cylinder structure for gas storage, high pressure cylinder are made by combined material, and the frame is constituteed by the multilayer power, alternately accomplishes by one-way component and one-way combination, and inside is airtight inner shell for supply and release gas, and this frame is made by the airtight shell of capillary sclerosis, and then reaches the purpose of guaranteeing the storage of high quality and large capacity gas and safe quick gassing.
