(ANG).Liquefied natural gas (LNG) is generally stored in low-temperature storage tank with the state of liquefaction under 111.7K, 0.101325 Mpa,
There is the problems such as critical pressure is high, operating cost is high, and investment is big in using；Compressed natural gas (CNG) is by sky under 20 MPa
So gas compresses with the state of supercritical fluid and is stored in bomb, and current natural gas used for automobile uses more universal, but is using
In exist pressure high, supporting strict, the problems such as multi-stage compression system, potential safety hazard are many need to be equipped with；Absorbed natural gas (ANG) be
By the adsorption of the solid absorbent loaded in storage tank, reach under relatively low pressure store (3-4 MPa) and realize compression sky
So the storage volume of gas (13-14 Mpa) left and right, absorbed natural gas compared with compressed natural gas, it is possible to increase sky under equal conditions
So gas stores the storage capacity of device or significantly reduces the effect of pressure store while keeping equal storage capacity, and therefore exploitation is ground
Studying carefully absorbed natural gas (ANG) and become focus instantly, developmental research absorbed natural gas (ANG) storage facilities also becomes one and becomes
Gesture.
But, the natural gas in ANG storage facilities adsorbs on the sorbent, is easily subject in absorption and desorption process
The impact of heat effect, adsorption process is an exothermic reaction, easily produces heat, makes the temperature liter of the whole environment of storage facilities
High and affect the adsorbent adsorbance to natural gas, same desorption process is an endothermic process, needs more heat ability
More natural gas it is desorbed out from adsorbent.
Summary of the invention
This utility model is for deficiency of the prior art, it is provided that a kind of low pressure adsorbent natural gas storage tank, simple in construction, behaviour
Facilitate, utilize phase transformation reaction agent and outer loop cooling water that tank inside plays heat absorption and the effect of heat release, be conducive to
The absorption of natural gas and desorption reaction, it is to avoid because temperature reason reduces adsorbance and the desorption rate of natural gas.

Part composition, wherein, described tank body is provided with air inlet, gas outlet, activated carbon import, phase transformation reaction agent import, phase transformation
Reactant exports, described tank interior active charcoal carrier ring, Stainless Steel Coil, and it is cold that described external jacket is provided with circulation
But water pipe, and it is equipped with water inlet and outlet, described air inlet and gas outlet are equipped with the nanofiltration core of special construction, described
Stainless Steel Coil in fill phase transformation reaction agent, and change conveniently, described external jacket is welded with tank body sealing；Described
Phase transformation reaction agent is the one in paraffin, nitric hydrate salt, hydration ammonia salt；The material of described nanofiltration core be rustless steel,
One in POROUS TITANIUM, and the aperture of nanofiltration core is at 0.5 ~ 2nm；Described activated carbon carrier ring is arranged to five layers, and
Using honeycomb-shaped structure on carrier ring, on honeycomb-shaped structure, the size in single hole is 3 ~ 6 nm.
This utility model can realize following effect:
1, phase transformation reaction agent and outer loop cooling water is utilized tank inside to play heat absorption and the effect of heat release, favorably
Absorption and desorption reaction in natural gas, it is to avoid because temperature reason reduces adsorbance and the desorption rate of natural gas；
2, the air inlet of storage tank and gas outlet are equipped with the nanofiltration core of special construction, and the aperture of nanofiltration core is arranged
At 0.5 ~ 2nm, effectively preventing adsorbent during inflatable and deflatable from being brought into pipeline by the natural gas under pressure, impact makes
With.
3, activated carbon carrier ring is arranged to five layers, and uses honeycomb-shaped structure on carrier ring, such is designed with beneficially
Adsorbent is uniformly distributed in storage tank, and in filling process, absorption is uniformly.
4, configuration phase transformation reaction agent is imported and exported, it is possible to changes the reactant of inefficacy more easily, improves efficiency.

Detailed description of the invention
In conjunction with accompanying drawing, detailed description of the invention of the present utility model is:
Embodiment 1
As shown in Figure 1, a kind of low pressure adsorbent natural gas storage tank described in this utility model embodiment, it is by tank body and outer
Portion's chuck two parts composition, wherein, described tank body is provided with air inlet, gas outlet, and activated carbon import, phase transformation reaction agent are entered
Mouth, phase transformation reaction agent outlet, described tank interior active charcoal carrier ring, Stainless Steel Coil, described external jacket is installed
Having circulating cooling water pipe, and be equipped with water inlet and outlet, described air inlet and gas outlet are equipped with the nanometer mistake of special construction

Connect；Described phase transformation reaction agent is hydration ammonia salt；The material of described nanofiltration core is POROUS TITANIUM, and the hole of nanofiltration core
Footpath is at 1nm；Described activated carbon carrier ring is arranged to five layers, and uses honeycomb-shaped structure on carrier ring, on honeycomb-shaped structure
The size in single hole is 4 nm.
When filling natural gas in natural gas storage tank, natural gas generation exothermic reaction, adsorption process are produced a large amount of by adsorbent
Heat, now water inlet and the outlet of the recirculated cooling water in external jacket is opened simultaneously, will circulation by extraneous high-pressure pump
Cooling water circulation in water pipe, utilizes recirculated cooling water to take away the partial heat outside natural gas storage tank, the most internal not
In rust steel disk pipe there is an endothermic reaction in phase transformation reaction agent, has siphoned away the amount of heat that internal adsorption process produces, and increases and inhales
The attached dose of adsorbance to natural gas；Equally, natural gas storage tank use natural gas time, natural gas is occurred heat absorption anti-by adsorbent
Should, desorption process needs amount of heat, and now the recirculated cooling water in external jacket is vented and closes Inlet and outlet water switch, in utilizing
There is an exothermic reaction in the phase transformation reaction agent in portion's Stainless Steel Coil, produces amount of heat, is desorbed natural air stripping to adsorbent
For enough heats, increase the adsorbent desorption rate to natural gas.
When phase transformation reaction agent poor effect when, external nitrogen compressor can be passed through, toward phase transformation reaction agent import department
High pressure is filled with nitrogen, makes the phase transformation reaction agent in Stainless Steel Coil discharge, and then adds new phase from phase transformation reaction agent porch
Become reactant, to ensure the balance of heat effect.
