Background
Fossil energy in China is greatly emphasized on coal, the proportion of the coal in primary energy in China is still up to 57% until 2020, and petroleum and natural gas only account for 19% and 10% respectively. Coal combustion produces large quantities of carbon dioxide (CO)2) Sulfur dioxide (SO)2) Nitrogen Oxide (NO)X) And Suspended Particles (TSPL)Substances cause serious pollution to the atmosphere and aggravate the greenhouse effect, natural gas is used as clean energy, carbon dioxide generated after combustion is less than other fossil fuels, the emission of sulfur dioxide and dust can be reduced by nearly 100%, and the environmental quality is fundamentally improved. From the perspective of energy consumption, the consumption proportion of clean energy in China is greatly improved in recent years, and in order to accelerate the process of economic sustainable development in China, China needs to adjust the energy structure and accelerate the development of clean energy such as natural gas.
The main storage and transportation modes of natural gas comprise three types: compressed Natural Gas (CNG), Liquefied Natural Gas (LNG), and Adsorbed Natural Gas (ANG). CNG is compressed and stored in a container in a gaseous state, has the advantages of early development and mature technology, is most widely applied to the natural gas storage technology, but needs high-pressure storage, so the requirements on the toughness and the strength of storage tank materials are higher, the manufacturing cost of the storage tank is increased, and the energy consumption is also increased; LNG is formed by converting methane into liquid through multiple processes, and has the limitations that the cooling process is complex, the manufacturing cost is high, and the low-temperature state is not easy to maintain in a complex environment;
the ANG is prepared by loading a special adsorbent with a high specific surface area into a storage tank at normal temperature and low pressure, adsorbing and storing natural gas by virtue of a huge inner surface area and a rich microporous structure of the adsorbent, so that the storage density of the storage tank is close to that of CNG, and the ANG serving as an automobile fuel has the characteristics of low storage pressure, safe and reliable driving, convenience in maintenance and operation, high economic applicability and the like. Because of these advantages, ANG becomes the best way for storing natural gas for vehicles, and is engaged in technical research by a large number of researchers at home and abroad, and the development prospect thereof is generally seen.
The natural gas in the ANG storage facility needs to be adsorbed on the adsorbent and is susceptible to thermal effects during the adsorption and desorption processes. The adsorption process is an exothermic reaction, and the released heat raises the internal temperature of the storage tank so as to reduce the adsorption quantity; the desorption process is an endothermic reaction, the temperature of the storage tank is reduced, so that the desorption amount is reduced, and more natural gas can be released by supplying heat.

The perforated plate 16 is provided with a water through hole, and the position of the water through hole corresponds to the position of a round hole at the intersection of the longitudinal slotted fins 4. Two transverse fins 3 and three longitudinal slotted fins 4 which are arranged transversely and vertically in a cross shape are arranged in the flat tank body, the fins 3 and the fins 4 are welded with the perforated plate 16, round holes are formed in the cross position, the upper round hole and the lower round hole of each longitudinal slotted fin can respectively enter and exit cooling water holes, and the round holes in the fin cross position correspond to the respective water through holes of the perforated plate 16. Certain small gaps are reserved between the transverse fins 3 and the longitudinal grooved fins 4 and the inner side of the tank body 1, so that the formed adsorbent 5 is convenient to take out and replace. The inside of the tank body 1 is divided into a plurality of cuboid empty grooves by the transverse fins 3 and the longitudinal slotted fins 4, the middle part of the empty groove is vertically provided with the porous air charging and discharging pipe 2, and the whole empty groove is filled with the molding adsorbent 5 arranged around the porous air charging and discharging pipe 2.
In the invention, the lower end of the tank body 1 is provided with a support 10, and the support 10 is U-shaped.
In the invention, the tank body 1 is in a flat hollow cuboid shape, so that the storage tank is convenient to install in an automobile, and meanwhile, the storage tank does not occupy too much volume in the automobile, and the conformability is improved.
In the invention, the adsorbent 5 is a molded adsorbent, has a larger size and a certain shape, higher bulk density and strength, and is convenient to replace because of no dust pollution compared with a powdery adsorbent.
In the invention, the transverse fins 3 and the longitudinal grooved fins 4 are both made of materials with good heat conductivity, the fins are transversely and longitudinally divided into a plurality of parts in the tank body, and spaces are reserved in the fins to enable cooling water to flow. The heat conduction fin can be discharged after heat generated in the adsorption process is introduced into flowing cooling water in the fin in time, or heat is brought for the desorption process, and the influence of the adsorption heat effect is reduced.
In the invention, the porous charging and discharging gas pipe 2 is welded on the gas seal head 13 and the holding tube plate 7 of the tank body 1, is inserted into the tank body 1 and is wrapped by the formed adsorbent.
All the transverse fins 3 and the longitudinal grooved fins 4 are processed by steel plates with certain thickness, cooling water flow passages 11 with certain shapes are milled on the surfaces of the steel plates, and two same steel plates are butt-welded to form closed cooling water flow passages 11.

Similarly, when the natural gas storage tank uses natural gas, namely the automobile runs, the adsorbent has an endothermic reaction on the natural gas, a large amount of heat is needed in the desorption process, the circulating cooling water in the fins comes from the cooling water of the engine, the temperature of the cooling water of the engine can reach 80-95 ℃ in the running process, enough heat can be provided for the adsorbent to desorb the natural gas, or the afterheat of the tail gas of the engine is used for providing heat, so that the desorption amount of the adsorbent to the natural gas is increased.
When the adsorbent adsorption capacity is not good, the gas seal head 13 and the connecting flange 12 of the tank body 1 can be disassembled, and the adsorbent 5 formed in the tank body 1 can be replaced, so that the driving mileage of the automobile can be guaranteed.
Example 2
