Description

Large-scale high-pressure gas holds device
Technical Field
The invention relates to the technical field of high-pressure containers, in particular to a large high-pressure gas containing device.
Background
Under the condition of a certain design pressure, the volume of the spherical container is related to the thickness of the spherical shell made of a specific material, and the thickness is thicker when the volume is larger. The maximum thickness that can be achieved by the spherical shell is related to the material manufacturing level and the pressing level of the manufacturing plant. The steel plates adopted by the existing spherical container are mainly divided into two types: a heat-treated high-strength steel represented by 07MnMoVR and a medium-strength steel represented by Q345R. Under the concept of the traditional spherical container, the manufacturing of the high-pressure spherical container with larger volume cannot be completed by adopting the two kinds of steel because:
1. for tempered high-strength steel, the wall thickness of the spherical shell adopting the steel is thinner under certain pressure and certain volume, however, the manufacturing level of the current steel manufacturing factory cannot reach the steel plate with the thickness required by the large high-pressure spherical container, the thickness of the available steel plate with uniform and reliable performance is smaller, and the maximum allowable use thickness of the high-strength steel plate is 60 mm;
2. for the mature medium strength steel Q345R, under certain pressure and certain volume, the wall thickness of the spherical shell adopting the steel is far greater than that of the high strength steel, the maximum steel plate thickness of the steel can reach 200mm, but for a spherical container manufacturer, the steel plate with the thickness of 200mm presses the thick steel plate into an accurate spherical shell plate, and then the assembly welding difficulty is very large, and the assembly welding quality cannot be guaranteed. Moreover, because the spherical container has high risk, the national standard GB 150-.
Another way of manufacturing high pressure vessels is to achieve the ability to withstand high pressure by multi-layer wrapping of sheet steel on the inner cylinder, but this form is only applicable to cylindrical vessels, spherical vessels cannot be multi-layer wrapped due to their spherical shape.
The above factors have resulted in the inability of high pressure spherical vessels of large volume to be uniform in all forms and methods.

Compared with a cylindrical container, the spherical container has the smallest surface area under the same volume and the same pressure, so that the required steel area is small; the spherical container wall has the smallest and uniform stress in the same diameter, and the bearing capacity is 1 times larger than that of the cylindrical container, so the thickness of the plate of the spherical container is only half of the thickness of the plate of the corresponding cylindrical container wall. The spherical container volume can be made larger with the same pressure and steel plate thickness. The invention is characterized in that a smaller spherical container is positioned inside a larger spherical container, the inner spherical container provides high pressure, and the outer spherical container provides necessary assistance for the high pressure of the inner spherical container.

(6) The annular seat in the second support can increase the area of contact with the holding surface, and the perforation is used for fixed external pipe in addition, and the pressure during preventing to ventilate is acted on rather than the second breather pipe of being connected, leads to the second breather pipe to rock for outer ball container, has reduced outer ball container's gas tightness.
(7) The setting of whole forging has guaranteed the leakproofness of first breather pipe, prevents to take place to mix between the gas of the interior gas of ball container, interior gas between ball container and the outer ball container.
(8) The support in this scheme is the cooperation that adopts stay cord and pillar, adjusts the stay cord and adjusts the height that corresponds the container on the stay cord, and especially interior ball container is when not welding, constantly adjusts the height of interior ball container through the elasticity of stay cord to better welding is on the first breather pipe of having fixed on outer ball container.
