Description
Technical Field
The utility model belongs to the technical field of natural gas recovery, and particularly relates to an adsorption type natural gas storage device.
Background
The natural gas is used as clean energy, no waste residue and waste water are generated after combustion, and the natural gas has the advantages of safe use, high heat value, cleanness and the like. The natural gas has wide sources and is widely applied to the fields of power generation, chemical raw materials, civil and commercial gas, vehicle energy and the like. However, at supercritical conditions at standard temperature and pressure, natural gas has a very low density, which results in natural gas having a very low volumetric energy density compared to conventional liquid fuels. Therefore, certain technical measures are required to achieve the aim of normally using a large amount of natural gas. The country clearly proposes to expand the use of natural gas, but the utilization speed and development scale of the natural gas are limited by the natural gas storage link between the production place and the market.
At present, natural gas storage methods can be divided into: compressed Natural Gas (CNG), Pipeline Natural Gas (PNG), Liquefied Natural Gas (LNG), Adsorbed Natural Gas (ANG), and hydrated Natural Gas (NGH). At present, the pipeline transportation of natural gas is the most important mode for transporting natural gas on a global scale and is suitable for long-distance transportation. The compressed natural gas storage pressure is up to 20MPA, and the method can be applied to CNG automobiles, district gas supply, city natural gas pipeline network peak regulation and other aspects. The CNG technology in China has been developed for more than 20 years, a mature industrial model is formed, and the advantages of the CNG technology are increased day by day along with the increase of the price of fuel oil. However, the CNG technology has the problems of high energy consumption of multi-stage compression, large investment of high-pressure filling equipment, heavy quality of a high-pressure gas cylinder, high cost and other safety performances to be further improved. LNG is a technology for liquefying natural gas at a temperature lower than the boiling point (-161 ℃) of the natural gas for low-temperature storage, has very high requirements on the design and supply processes of a storage container, and is only suitable for part of automobile transportation industries. NGH is gradually paid attention as a new natural gas safe storage and transportation technology, but the requirement on storage and transportation conditions is high, and the industrial development and application of releasing natural gas from hydrate in a transition state are still in an experimental stage. In comparison, the ANG technology for obtaining high storage energy density through physical adsorption under a low pressure state has incomparable advantages in the aspects of adsorption and manufacturing technology and safety performance compared with CNG, and shows huge potential in the aspects of flexibly trying out and developing downstream markets, reducing the rigidness and risk of a single storage and transportation mode and enriching the industrial chain of natural gas.
The technology of adsorbing and storing natural gas (ANG) is that a special natural gas adsorbent with a high specific surface area is filled in a container, and the storage energy density close to that of CNG under high pressure can be obtained at normal temperature and medium pressure (6.0Mpa) of only 1/4-1/5 by utilizing the huge internal surface area and abundant micropore structures of the adsorbent. When the pressure in the container is lower than the outside, the gas is adsorbed on the surface of the micropores of the adsorbent solid to be stored; when the pressure of the outside is lower than the pressure in the container, the gas is desorbed from the surface of the adsorbent solid and supplied to the outside. This adsorption phenomenon is referred to as physical adsorption.
The adsorption storage and transportation technology mainly comprises the preparation of an adsorbent and related technical research thereof, wherein the preparation of the adsorbent mainly comprises two technical elements: preparation and forming technology of powder adsorbent. In contrast, the preparation and forming technology of the adsorbent and the research on the relevant practical performance are relatively mature, but the development of the adsorption container is gradually carried out along with the increase of the demand of industrial application in recent years. However, there is no method for manufacturing and storing the adsorption natural gas cylinder.
