Description
Technical field
The utility model belongs to chemical industry apparatus field, and in particular to a freeze proof LNG gasification device, wherein the freeze proof LNG
Gasifier can keep good service performance when using under circumstances.
Background technique
Liquefied natural gas (LNG) has become the main gas source or transitional gas for not being available pipeline gas gas supply city at present
Source and many supplement gas sources or peak regulation gas source using pipeline gas gas supply city.Since liquefied natural gas is by increasingly
It is widely used in real life, LNG gasification station is also met the tendency of, and LNG gasification station is one and receives, stores and distribute
LNG satellite station and cities and towns or gas enterprise from manufacturer transfer LNG to the intermediate regulations place of user.LNG gasification station with
By means of its construction period it is short and can the satisfaction gas market demand rapidly advantage, gradually in the numerous economic hairs of China's southeastern coast
It reaches, the small and medium-sized cities of energy shortages are built up, the transition gas supply facility before becoming permanent gas supply facility or pipeline gas arrival.
In LNG gasification station, liquefied natural gas LNG in gasification station by gasification installation gasify after, through pressure regulation, metering,
The processes such as smelly are added to be sent into gas ductwork.Applied in LNG gasification station most commonly be air-heating type gasifier, ice-cold liquid natural
Gas is by reforming into gaseous gas after gasifying in air-heating type gasifier.
Air-heating type gasifier is a kind of superficial air heat exchanger, and inside is implemented as finned tube structure.Usually, air temperature type
At work, about -150 DEG C of temperature of liquefied natural gas LNG enters tube side to gasifier, and liquefied natural gas LNG absorbs surrounding air
Heat needs constantly to overheat it to flash to gas；During this period, into the air in gasifier from upper
And it is lower along fin flowing, it releases heat and is supplied to liquefied natural gas LNG.At this point, due to a large amount of heat absorptions of gasifier, gasifier week
Enclosing temperature can drastically reduce, and the large quantity of moisture in air is in the frosting of gasifier surface, icing, moisture condensation, so as to cause gasifier hair
Raw phenomena such as freezing.
Once and gasifier phenomena such as freezing, can cither indirectly or directly cause some problems.First, gasifier occurs
The heat exchange efficiency for meaning that the gasifier freeze for sharp fall, and in actual application, when a certain gasifier
Due to due to icing and heat exchange efficiency reduce when, this group of gasifier needs are stopped using and are thawed, to restore exchange capability of heat,
In thawing the stage for the gasifier, it is necessary to put into another gasifier, mean that LNG gasification station needs to be arranged more gas in this way
Change device, the cost of manufacture for not only increasing only gasification station also increases its occupied area.
Second, freezing for gasifier surface can melt to form ice water during thawing, the ice water under the effect of gravity
Gasifier basis buttress surface is flowed to, may be frozen in gasifier surface second.That is to say, gasifier thaws inherently
One inefficient thing.
Third, the work and change ice, gasifier with gasifier are chronically in a kind of state of Frozen-thawed cycled.Due to gas
Change device buttress and be generally used reinforced concrete structure, there is a large amount of bubble and tiny cracks on surface.Therefore when ice melts
When being melted into water, water is largely present in bubble and crack, and when gasifier reruns, temperature decline, these water will freeze and body
Product expansion, further increases crack.Will lead to concrete in cycles slowly to crack and peel off, and the reinforcing bar in buttress lose it is mixed
The protection for coagulating soil will also be corroded, this greatly reduces the safety on gasifier basis.
Certainly, also there are certain measure of taking, such as jacket water (J.W.) heating, equipment for the heat preservation of gasifier in the prior art
Pipeline ties up heating tape plus simple insulating layer, greenhouse etc. is set up outside equipment, but the heat insulation effect of these measures is all
It is bad, that is to say, the anti-freezing property of the gasifier of the prior art is not able to satisfy the needs of real life production still.

Fig. 1 is the structural schematic diagram of the freeze proof LNG gasification device of an embodiment according to the present utility model, as shown, institute
Stating freeze proof LNG gasification device includes gasifier buttress 10, and is set in turn in the waterproof layer 20 of the gasifier buttress 10, heat preservation
Layer 30 and protective layer 40, wherein the waterproof layer 20 is layed in the outer surface of the gasifier buttress 10 to effectively prevent outside
Moisture enters the gasifier buttress 10, and the insulating layer 30 is layed in the outer surface of the waterproof layer 20 to play heat-insulation and heat-preservation
Effect, the protective layer 40 is set to the periphery of the waterproof layer 20 and the insulating layer 30 to protect overall structure.
Specifically, the gasifier buttress 10 has the structure similar with the gasifier buttress of most of type, therefore
It is no longer illustrated herein with excessive content, the characteristics of freeze proof LNG gasification device provided by the utility model is the gas
Change 10 outer surface of device buttress and be laid with multiple function layers, the functional layer cooperating is so that the freeze proof LNG gasification device has
Good frost resistance, so as to keep good service performance in actual use.
When the gasifier buttress 10 is applied to gasification liquefied gas LNG, the working principle of the gasifier buttress 10
As follows: about -150 DEG C of temperature of liquefied natural gas LNG enters in the gasifier buttress 10, and liquefied natural gas LNG absorbs environment
Atmospheric heat needs constantly to overheat it to flash to gas；During this period, into the gasifier buttress
Air in 10 flows from above to below, and releases heat to be supplied to liquefied natural gas LNG.
The gasifier most often suitable for LNG gasification station is mainly air-heating type gasifier at present, and air-heating type gasifier is to utilize
Natural convection air heating low temperature LNG is vaporized into the heat exchange equipment of gas at normal temperature.It presses certain spacing by aluminum finned tube
