Embodiment Construction

[0012] Below in conjunction with embodiment the utility model is further described:

[0013] The regenerative natural gas adsorption storage tank includes a tank body 3 with a manhole 6 at the upper end of the tank body 3. The manhole 6 is used to load and unload the pressure-resistant metal pipe 4, metal mesh 7, and carbonaceous natural gas adsorbent 8. A metal mesh 7 is arranged between adjacent two layers of natural gas adsorbents 8 in the body 3, and the metal mesh 7 plays a role in supporting the natural gas adsorbent and making the natural gas evenly distributed into the tank body, and the metal mesh 7 is inflated and deflated It plays the role of accelerating mass transfer and heat transfer, and the metal tubes 4 are placed in rows on the metal mesh 7 at intervals. The metal tubes 4 are equipped with heat storage substances, and the heat storage substances are composed of: Ca(NO 3 ) 2 4H 2 O, Na 2 HPO 4 ·7H 2 O, CH 4 COONa·4H 2 O, Na 2 S 2 o 3 ·5H 2 O, Na 2 ...

Abstract

The invention discloses a heat accumulating type tank for absorbing and storing natural gas. The heat accumulating type tank comprises a tank body (3); and the interior of the tank body (3) is provided with multi-layer natural gas adsorbent (8), multi-layer metal meshes (7), and multi-layer metal tubes (4), wherein, heat accumulating material is arranged in the metal tubes (4). The heat accumulating material in the invention can adjust the temperature in the storage tank during the adsorption and desorption of the natural gas, so as to reduce heating effect and improve storage and transportation efficiency, thus not only solving the problem of recovering scattered natural gas in remote areas, but also being applied to large-scale natural gas storage and transportation and natural gas refueling stations.

Description

Technical field: [0001] The invention relates to a storage tank used for transporting natural gas in the field of petrochemical industry, in particular to a regenerative natural gas adsorption storage tank. Background technique: [0002] In existing natural gas storage systems, whether it is liquefied natural gas or compressed natural gas, in order to increase the gas storage capacity, the usual method is to increase the pressure. However, after the gas pressure is increased, the thickness of the tank body will be increased, which will increase construction costs, safety hazards and other disadvantages. [0003] Invention patent (CN2546723Y) In order to increase the gas storage capacity, an electric heating element is installed inside the gas storage tank, thereby reducing the thermal effect, and the gas storage capacity is 2.5 times that of the existing medium-pressure gas storage tank; the safety performance is good, and the gas storage pressure is low , improve the safet...
