Composite natural gas adsorption layers (8) are transversely paved in the tank body at intervals. Metal meshes (7) are placed on the composite natural gas adsorption layers (8). Metal pipes (4) are uniformly distributed on the metal meshes (7). Heat accumulation materials are arranged in the metal pipes. The heat accumulation materials can be used for regulating a temperature in the storage tank in the adsorption and desorption process of natural gas so as to reduce the thermal effect and improve the storage efficiency. According to the utility model, not only is the problem of recovery of the scattered natural gas in remote areas solved, but also the heat accumulation type natural gas adsorption storage tank an be applied to large-scale natural gas storage and a natural gas refueling station.
Description
Technical field
The utility model relates to the used a kind of storage tank of transport natural gas in the petrochemical industry, especially a kind of heat accumulating type storage tank for absorbing natural gas.
Background technique
No matter existing rock gas stocking system is LNG Liquefied natural gas or compressed natural gas, and in order to increase gas-storing capacity, usual way is to increase pressure.But gas increases after the pressure, can increase tank body thickness, increases drawbacks such as construction cost, potential safety hazard.
Patent of invention (CN2546723Y) is provided with electrothermal piece in order to increase gas-storing capacity in gas holder inside, thereby reduces thermal effect, and gas-storing capacity is existing middle 2.5 times of pressing the equal gas-storing capacity of gas holder; Safety performance is good, and gas storage pressure is low, the Security of raising equipment and operation; This gas holder reduces more than 30% than the gas storage cost of existing gas holder.But have some drawbacks, some retail natural gas well location is not supplied power in remote districts yet; Therefore limited the application area that contains the electrothermal piece natural gas storage tank; Utilize electric heating element to eliminate thermal effect in addition, consume a large amount of electric energy, thereby also increased the storage cost of transportation of rock gas.
Patent of invention (CN1792784A) relates to a kind of vehicle carried type steel cylinder, buries energy-storage travelling wave tube underground to increase the gas-storing capacity of rock gas.The present invention because simple in structure, volume is little, thereby only is applicable to vehicle-mounted steel cylinder, is not suitable for the storage and transportation apparatus of extensive rock gas.
Summary of the invention
In order to overcome the deficiency that exists in the background technique, the utility model provides a kind of heat accumulating type storage tank for absorbing natural gas, utilizes the phase transformation of heat storage material self to regulate the temperature in the storage tank for absorbing natural gas, thereby has improved accumulating efficient.It not only can solve retail natural gas recovery problem from far-off regions the present invention, can also solve the extensive accumulating problem of rock gas.
The technological scheme that the utility model adopts is: this heat accumulating type storage tank for absorbing natural gas comprises tank body; In tank body, transversely be equipped with composite natural gas adsorbent layer at interval; On composite natural gas adsorbent layer, be placed with wire netting; Even distribution metal tube is equipped with heat storage material on the wire netting in the metal tube.
The use of the utility model comprises the inflation and two processes of exitting: (1) gas replenishment process: when natural aspiration attaches storage tank system and inflates; Because the existence of thermal effect; Core temperature can reach 100 ℃ when the natural gas storage can system was at room temperature inflated; The interior heat storage material of storage tank this moment undergoes phase transition most of heat of emitting when absorbing the inflation of natural gas storage can system, makes the interior temperature maintenance of storage tank at 40-50 ℃.(2) deflation course: when the rock gas storage tank system is exitted; Because the existence of thermal effect; Minimum temperature can be reduced to subzero when the natural gas storage can system was at room temperature exitted; The interior heat storage material of storage tank this moment undergoes phase transition emits heat, makes the interior temperature maintenance of storage tank at 5-15 ℃.
The utility model compared with prior art has the following advantages and the high-lighting effect: 1, the utility model adopts a kind of new type compound natural gas adsorbent, and adsorption performance is good, thereby can effectively increase rock gas gas storage efficient.2, bury the multiple layer metal net underground in the natural gas adsorbent storage tank, main effect is when carrying out rock gas absorption and desorption, to quicken mass transfer and heat transfer, quickening inflation and outgassing rate.3, owing in the natural gas storage tank heat storage material is housed, thus thereby the accumulating efficient that can regulate the temperature increase rock gas in the storage tank well.Utilize self phase-transition heat-storage, reduce the waste of other energy, improve energy utilization rate.4, apparatus body is simple in structure, and construction cost is low, both can make the mini gas storage tank, also is applicable to extensive rock gas accumulating mode, also is applicable to that natural gas filling station storage rock gas uses.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The 1-blowhole, 2-air outlet hole, 3-tank body, 4-metal tube, 5-pressure gauge, 6-manhole, 7-wire netting, 8-composite natural gas adsorbent layer.
Embodiment:
Below in conjunction with embodiment the utility model is described further:
This heat accumulating type storage tank for absorbing natural gas comprises tank body 3; There is manhole 6 tank body 3 upper ends; Manhole 6 is filling and the unloadings that are used for carrying out withstand voltage metal tube 4, wire netting 7, composite natural gas adsorbent layer 8, is provided with wire netting 7 between the adjacent composite natural gas adsorbent layer 8 in the tank body 3, and wire netting 7 plays and support natural gas adsorbent, rock gas is evenly distributed gets into the effect of tank body; And wire netting 7 plays the effect of quickening mass transfer and heat transfer when inflation and venting; And metal tube 4 in a row is placed on the wire netting 7 at interval, and heat storage material is housed in the metal tube 4, and heat storage material undergoes phase transition storing heat when inflation; When venting, can emit heat, storage tank for absorbing natural gas need not be provided with electrothermal piece when transport natural gas can increase reserves.
When using the utility model, be divided into two processes: gas replenishment process and deflation course.
When (1) inflating, open the flow control valve of blowhole 1 top, make rock gas get into tank body; Because the existence of thermal effect; Liberated heat underwent phase transition and absorbs by being contained in heat storage materials in the metal tube 4 when the rock gas gas holder was absorbed natural gas, thereby increased the gas-storing capacity of rock gas gas holder, and pressure gauge 5 shows jar internal pressures simultaneously;, pressure stops inflation when reaching 3.5-4MPa, about 1.5-2 of time spent hour.
When (2) exitting, open the flow control valve of air outlet hole 2 tops, behind air outlet hole 2, outwards drawn by the natural gas flow of natural gas adsorbent absorption.
After repeatedly inflating and exitting, if the adsorptive power of natural gas adsorbent reduces, can utilize the method for heating to make natural gas adsorbent regeneration through the unloading of manhole to sorbent, easy to operate.The described heat accumulating type rock gas of the utility model absorbing and storing mode does not receive the restriction of region, is applicable to the storage tank of all kinds and size, is applicable to large-scale gasholder station stored-gas use yet.
