Description

Quick-open type copper lining high-pressure hydrogen storage container
Technical Field
The invention belongs to the field of hydrogen energy storage equipment development, and particularly relates to a quick-open type copper lining high-pressure hydrogen storage container.
Background
The storage of hydrogen is one of the core links of the hydrogen energy industry chain. High-pressure hydrogen storage is a mainstream hydrogen storage mode of hydrogen fuel cell automobiles, tube trailers, hydrogen filling stations and the like at present, and a high-pressure hydrogen storage container is a carrier for high-pressure hydrogen storage. Different from the conventional pressure vessel, the hydrogen storage vessel may face the material performance deterioration phenomenon caused by high-pressure hydrogen embrittlement in a high-pressure hydrogen environment, and great threat is caused to the safe operation of the vessel. Currently, the types of high pressure hydrogen storage vessels mainly include large volume seamless hydrogen storage vessels, austenitic stainless steel lined hydrogen storage vessels, and fiber wound composite bottle type hydrogen storage vessels.
The large-volume seamless hydrogen storage container is formed by spinning a seamless steel tube, has simple structure and low cost, can be produced in batches, but the hydrogen-contacting material is low alloy steel such as chromium-molybdenum steel and the like, and the material shows hydrogen embrittlement phenomena such as obvious ductility reduction, accelerated fatigue crack propagation rate, reduced fracture toughness and the like in a high-pressure hydrogen environment, thereby threatening the operation safety of the container. Meanwhile, as the strength of the material is higher and the hydrogen embrittlement is more serious, the upper limit of the tensile strength of the chromium-molybdenum steel material for the hydrogen storage container is regulated by the relevant standards at home and abroad (880 MPa at home and 950MPa at abroad generally), which causes that the potential of the mechanical properties of the material can not be fully exerted. Furthermore, when the hydrogen storage pressure is increased, the wall thickness of such a vessel increases, which makes spinning difficult and easily causes a phenomenon of quenching during heat treatment, which has an extremely adverse effect on the uniformity of the vessel along the wall thickness. At present, the container is often used in the situation that the pressure is less than 50 MPa.
The hydro-material of the austenitic stainless steel lining hydrogen storage container is austenitic stainless steel with good hydrogen embrittlement resistance such as 316L, and the like, and the container has high hydrogen storage pressure and large volume, but has complex structure (common steel belt winding type, laminate binding type and the like), long manufacturing period and high cost, and usually needs welding forming, and has very high requirement on welding process. In addition, the nondestructive testing of such containers is difficult due to the structural influence.
The bottle-type hydrogen storage container made of the fiber winding composite material is formed by winding a seamless steel pipe, an aluminum liner or a plastic liner and the like by carbon fibers and the like, has high hydrogen storage pressure, small hydrogen storage volume and higher cost of the materials such as the carbon fibers and the like, so the container is mainly used for hydrogen storage of hydrogen fuel cell automobiles at present and is not used for occasions of large-scale hydrogen storage such as a hydrogen refueling station and the like.
In view of the above, the present invention is proposed based on the current situation that the hydrogen embrittlement resistance, the use performance (storage pressure, storage volume, etc.), the manufacturing cost, etc. of the conventional high-pressure hydrogen storage container often cannot satisfy the requirements at the same time.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects in the prior art and provides a quick-opening copper lining high-pressure hydrogen storage container which has the advantages of good hydrogen brittleness resistance, high hydrogen storage pressure, large volume, relatively simple structure, convenience in manufacturing and low cost.
In order to solve the technical problem, the solution of the invention is as follows:
the quick-opening copper lining high-pressure hydrogen storage container comprises a hollow tubular copper lining for storing hydrogen, wherein the lining is sleeved in an outer cylinder of a hollow tubular structure and is in clearance fit with the outer cylinder; at least one end part of the outer cylinder is provided with a quick-opening end enclosure which is cylindrical and is sleeved in the outer cylinder in a threaded connection mode; a through hole is formed in the axial center of the quick-opening end socket, and the end part of the lining is sleeved in the through hole; on the outer end face of the quick-opening end socket, a joint at the end part of the connecting pipe is fixed on the quick-opening end socket through a component consisting of a flange and a bolt; the adapter end joint is tubular, the middle part of the adapter end joint is provided with a radial boss for positioning and transferring load, one side of the adapter end joint extends into the end part of the lining and is tightly matched with the end part of the lining, and the other side of the adapter end joint penetrates through an axial central through hole of the flange and is used for connecting an external hydrogen conveying pipe.
In the invention, two end parts of the outer cylinder are respectively provided with a quick-opening end socket, a connecting pipe end joint and a flange-bolt assembly, and have the same structure; or only one end part of the outer cylinder is provided with the quick-opening end socket, and the other end part is provided with a blind flange for plugging.
In the invention, the radial size of the end part of the lining sleeved on the central through hole of the quick-opening end socket is smaller than that of the main structure of the lining, namely, the reduced end part of the lining extends into the central through hole of the quick-opening end socket.
In the invention, the end surface of the inner side of the quick-opening end socket is in a shape matched with the end part of the lining, and the quick-opening end socket and the lining are in clearance fit.
In the invention, the outer part of the quick-opening end enclosure is provided with external threads, and the inner side of the outer cylinder is provided with internal threads; the tail end of the thread of the outer cylinder is provided with a step structure for positioning when the quick-opening end enclosure is installed.
In the invention, O-shaped sealing rings are respectively arranged between the quick-opening end socket and the outer cylinder and between the joint at the end part of the connecting pipe and the lining for strengthening sealing.
In the invention, one side of the adapter at the end part of the adapter extending into the end part of the lining has larger radial dimension, and the side surface is provided with a circumferential groove for installing an O-shaped sealing ring.
In the invention, a plurality of threaded holes are uniformly arranged on the end surface of the outer side of the quick-opening end socket along the circumferential direction, and the end joint of the connecting pipe is fixed on the quick-opening end socket by using a stud, a bolt and a flange.
Compared with the prior art, the invention has the beneficial effects that:
1. the lining of the high-pressure hydrogen storage container adopts oxygen-free copper and other materials with good ductility and hydrogen embrittlement resistance, and when the container is filled with high-pressure hydrogen, the copper lining can effectively prevent the high-pressure hydrogen from contacting the outer cylinder, so that the material performance deterioration of the outer cylinder caused by high-pressure hydrogen embrittlement is avoided. Meanwhile, the lining material has good ductility, so that the lining can be tightly attached to the inner wall of the outer barrel when being pressed, and the stress can be fully transferred to the outer barrel, so that the outer barrel mainly bears the pressure of hydrogen.
2. Because of the obstruction of the copper lining, the outer cylinder of the container can be made of the prior chromium-molybdenum steel material. As the chromium-molybdenum steel material belongs to a non-hydrogen material, the strength of the chromium-molybdenum steel material is not limited any more, the regulation of the existing standard on the strength of the chromium-molybdenum steel material for the hydrogen storage container can be broken through, the potential of the mechanical property of the chromium-molybdenum steel material is fully exerted, and the lightweight design of the container is facilitated.
3. Because the quick-opening end enclosure is adopted, the outer cylinder of the container does not need spin forming and is easy to carry out heat treatment in a double-sided quenching mode, so that the thickness of the outer cylinder is mainly calculated and determined by hydrogen storage pressure and is not limited by manufacturing processes such as spin forming, heat treatment and the like, and the container is high in hydrogen storage pressure and large in volume.
4. The quick-opening end enclosure is adopted, so that the inner cylinder and the outer cylinder can be conveniently installed, the container is simple to manufacture, batch production can be realized, and the container is low in cost because the adopted materials such as oxygen-free copper, chromium-molybdenum steel and the like are common metal materials. The vessel is therefore able to meet the requirements for large-scale hydrogen storage.
