Description
Technical field
This utility model belong to utilize solar energy gasify technical field of LNG, utilize solar energy particularly to one
The system of heat pump gasification LNG (liquefied natural gas).
Background technology
Natural gas can be liquefied as the liquid of colorless and odorless, referred to as liquefied natural gas under-162 DEG C and normal pressure
(LNG).Owing to after natural gas liquefaction, volume energy reduces 600 times, it is simple to store economically and transport, therefore,
A lot of countries and regions, the whole world carry out natural gas trade with the form of LNG, and meanwhile, many countries utilize LNG
Area away from gas field and without long-distance transport pipes domestic to this country supplies.When LNG is as fuel or the raw material of industry,
Certain heat must be provided to be vaporized into gas at normal temperature state by gasifier before using.Heat can be from environment
Air and water obtain, it is also possible to by fuel combustion, hot water or steam obtain.
Conventional gasifier has air-heating type gasifier, open-frame type gasifier, submerged combustion gasifier and water-bath
Formula gasifier.
Air-heating type gasifier utilizes the air gasification LNG under atmospheric environment, when temperature is relatively low, gasifier table
Easily there is heap frost icing phenomenon in face, has a strong impact on the vaporization ability of gasifier, so typically using two groups of skies
Heating type gasifier, during one group of defrosting deicing, another group runs gasification LNG, and this not only increases equipment investment,
And floor space is big.Meanwhile, during air-heating type gasifier gasification LNG, the moisture in air runs into cold
Surface can dew condensation, through measuring and calculating, 15 DEG C, in the environment of relative humidity 60%, gasification produces 1Nm3
Natural gas will produce 0.1L condensed water, generally these condensed waters and directly discharge, and cause the biggest waste, also
Ecological environment around is caused impact.
Open-frame type gasifier utilizes river, river, lake, water LNG in the sea, the water after gasification flow back to again river,
River, lake, sea, the water of these natures is during gasification LNG, owing to low temperature can cause microorganism in water
Death, and the water after open-frame type gasifier is expelled back into river, river, lake, sea can affect ecology of water
Environment.
Submergible combustion burner utilize fuel gas buring directly in water discharge flue gas, add hot water, hot water along
The pipeline of gasifier flows up the LNG adding in heat pipe, has the highest thermal efficiency, but burning needs to consume
A certain amount of natural gas, it is also desirable to utilize water resource as heat exchange medium.
Water bath type gasifier utilizes the LNG in hot water heating gasifier pipe to be vaporized, owing to hot water forces stream
Dynamic, and internal-external temperature difference is big, water bath type gasifier has the advantages that size is little, but need to consume a large amount of electric energy or
Hot water prepared by Fossil fuel, it may also be necessary to consume water source.
