Description

Technical Field

[0001] The utility model relates to the field of CNG storage and transportation, and in particular to a large-volume movable gas storage. Background Art

[0002] As the national environmental protection requirements become more and more stringent, the demand for clean energy is increasing. CNG, as a clean energy, has a wide range of uses. At present, CNG transportation generally relies on tube bundle containers and long tube trailers. Due to the limitations of vehicle weight and box body, the transportation capacity of CNG must be increased while ensuring transportation safety. When multiple high-pressure gas cylinders are installed in the box, during transportation, the high-pressure gas cylinders are prone to shaking, and adjacent high-pressure gas cylinders collide or collide with the box body, which is prone to danger, thus failing to meet the needs of large gas-using equipment, failing to reach the maximum volume within the scope allowed by the specification, and low transportation efficiency.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] In the description of the utility model, it should be understood that the terms "front", "rear", "upper", "lower", "left", "right" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the utility model. The utility model is further described below in conjunction with the drawings and embodiments.

[0023] This embodiment discloses a large-volume movable gas storage, including a gas storage frame 1, a high-pressure gas cylinder 2, a support plate 4, a flange 5 and other components. The material of the gas storage frame 1 is Q355E rectangular tube, and its minimum operating environment temperature is -40°C. The size of the gas storage frame 1 is the international standard 40-foot container size, which is convenient for transportation. Support plates 4 are welded on the front and rear end faces of the gas storage frame 1 to facilitate the subsequent installation of high-pressure gas cylinders 2.

[0024] In this embodiment, four rows of high-pressure gas cylinders 2 are arranged in the gas storage frame 1, and the number of high-pressure gas cylinders 2 in each row is 3. The front and rear ends of the high-pressure gas cylinder 2 are both bottle mouths for assembling end plugs, and external threads are processed on the outer periphery of the front and rear ends of the high-pressure gas cylinder 2. Such a design facilitates threaded connection with the flange 5. After the flange 5 is connected to the end of the high-pressure gas cylinder 2, the flange 5 is fixed to the support plate 4 by a bolt assembly, so that the high-pressure gas cylinder 2 is fixed in the gas storage frame 1. In order to prevent the high-pressure gas cylinder 2 from rotating during movement, a cylindrical pin 7 is used to position the threaded connection of the flange 5. In order to improve the firmness of the high-pressure gas cylinder 2, the high-pressure gas cylinder 2 at the bottom layer is fixed to the bottom of the gas storage frame 1 by a binding belt 3.

[0025] In this embodiment, in order to adapt to use, the high-pressure gas cylinder 2 is designed by finite element stress analysis, and the structure is optimized under the premise of ensuring safety, and the wall thickness of the high-pressure gas cylinder 2 is controlled to 14.8 mm, which effectively reduces the thickness of the high-pressure gas cylinder 2. Sealant is applied to the threaded connection between the high-pressure gas cylinder 2 and the end plug 6, and two sealing rings 8 are set between the high-pressure gas cylinder 2 and the end plug 6 for sealing.

[0026] Through the large-volume movable gas storage reservoir described in the utility model, each high-pressure gas cylinder 2 is connected to the front and rear ends with a flange 5, and the two flanges 5 are respectively connected to the support plates 4 on the front and rear end surfaces of the gas storage frame 1, so that multiple high-pressure gas cylinders 2 can be fixed in the gas storage frame 1, and the high-pressure gas cylinders 2 will not shake. The overall water volume can reach 39.2 cubic meters, with a large transport capacity, a large volume-to-weight ratio, and high transportation efficiency, which can meet the needs of large equipment such as gas turbines and gas boilers.
