Description
Technical Field
The utility model belongs to the technical field of natural gas storage and transportation, and particularly relates to an adsorption type natural gas filling device.
Background
Natural gas is a clean and efficient energy source, has huge reserves, and depends on storage and transportation technology for popularization and application. Central cities and industrial enterprises using a large amount of gas are far away from gas sources, and natural gas at the gas source point needs to be safely, stably and continuously delivered to users, and five mainstream natural gas storage and transportation technologies exist at present. There are three common storage and transportation techniques, including natural gas Pipeline (PNG) storage and transportation, Compressed Natural Gas (CNG) storage and transportation, and Liquefied Natural Gas (LNG) storage and transportation; the novel storage and transportation technology comprises storage and transportation of adsorbed stored natural gas (ANG) and storage and transportation of Natural Gas Hydrate (NGH). With the market entry of a large number of natural gas vehicles (mainly buses and taxis), the storage mode of natural gas vehicle fuel is more widely concerned, and at present, three storage modes of Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) and Adsorbed Natural Gas (ANG) can be used for storage and transportation of natural gas vehicle fuel. The technology of adsorbing and storing natural gas (ANG) belongs to physical adsorption, and is a technology of adsorbing and storing natural gas at normal temperature and medium pressure (6.0MPa) by using huge internal surface area and abundant microporous structures of a special natural gas adsorbent with a high specific surface which is filled in a storage tank. ANG has the great advantage that the stored energy density close to that of CNG (compressed natural gas) under high pressure (20MPa) can be obtained under low pressure (3.5-6.0 MPa, which is only 1/4-1/5 of CNG). When the pressure in the storage tank is lower than the outside, the gas is adsorbed on the surface of the adsorbent solid micropores for storage; when the pressure in the storage tank is higher than the outside, the gas is desorbed from the surface of the adsorbent solid and is supplied to the outside. At present, oxy-acetylene cutting blanking is dominant in a plurality of steel structure manufacturing enterprises, the production cost is higher, and the potential safety hazard of steel cylinder transportation and carrying is large. And the processing profit of the steel structure is slight, so that the steel structure can only be used for digging potential and reducing consumption in production, the cost is reduced, and the competitiveness and the adaptability of enterprises are improved.
