Description
Technical field
Carburetor structure field is used the present invention relates to ship, more particularly to a kind of ship LNG vaporization of utilization river heat supply
System.
Background technology
Begin to use liquefied natural gas in modern rivers ship（Liquefied Natural Gas, abbreviation LNG）As
One of fuel of internal combustion engine, liquefied natural gas natural gas is compressed, be cooled to its boiling point（-161.5℃）Become liquid after temperature,
Usual LNG storage is in -161.5 degrees Celsius, the low-temperature storage tank of 0.1MPa or so, and main component is methane, public
It is fossil energy most clean on the earth to recognize.Colourless, tasteless, nontoxic and non-corrosiveness, its volume is about same amount gaseous natural gas
The 1/625 of volume, the quality of liquefied natural gas is only 45% or so of consubstantiality ponding.Its manufacturing process is first to produce gas field
Natural gas purification processing, obtains through the liquefaction of a succession of ultralow temperature, Er Qiefang very small to air pollution after liquefied natural gas burning
The heat for going out is big, so liquefied natural gas is a kind of more advanced energy.
LNG vaporization device is to utilize heat exchange principle, and external heat source is absorbed so that liquefied natural gas reaches vapour by heating agent
Change natural gas transportation after temperature from gas pipeline to power parts such as internal combustion engines, traditional vaporizer uses independent heating unit
Part heat supply, such as heating tube, steam mode, it is necessary to consume fuel for vaporizer provides thermal source, and total system is huger, due to
The reason for structure internal combustion engine and vaporizer between have a certain distance, and heat had during transport it is big scatter and disappear so that
Causing the thermal efficiency is reduced, and the operating efficiency of LNG vaporization device is also decreased.
There is an optimum working temperature, after usual internal combustion engine reaches specified optimum working temperature, can lead to during internal combustion engine
Internal circulation system is crossed to discharge waste heat, and internal combustion engine exhaust temperature also up to 600 DEG C or so, it is how many using internal combustion engine
Waste heat amount and exhaust temperature are then a technical barriers anxious to be resolved for LNG vaporization device provides thermal source.
The content of the invention
The purpose of the present invention is directed to problem above, there is provided a kind of ship LNG vaporization system of utilization river heat supply.
The technical solution adopted by the present invention is：
Using the ship LNG vaporization system of river heat supply, including river house steward, stop valve, outer cooling pump, charge air cooler, smoke evacuation water
Set, ethylene glycol heat exchanger, screw down nonreturn valve A, screw down nonreturn valve B, LNG vaporization device and internal combustion engine, river house steward is by cut-off
Valve is connected with outer cooling pump, and outer cooling pump is carried out cold in heat exchange by screw down nonreturn valve A and the heat that internal combustion engine is produced again
Device is connected, and charge air cooler is connected with smoke evacuation water jacket water inlet end, and smoke evacuation water jacket water side is connected with ethylene glycol heat exchanger, and ethylene glycol heat is handed over
Parallel operation is connected with LNG vaporization device, and the discharge outlet of ethylene glycol heat exchanger is equipped with screw down nonreturn valve B.
Described smoke evacuation water jacket is enclosed within interior combustion gas exhaust outlet pipe, and the high-temperature gas discharged when being worked using interior combustion gas is to water
Water in set carries out concurrent heating.
Described charge air cooler, its role is to reduce high temperature air temperature, the thermic load to reduce internal combustion engine after supercharging,
Improve air inflow, and then increasing combustion engine power.
Described ethylene glycol heat exchanger, is the heat exchanger by the use of ethylene glycol as heating agent, outstanding using ethylene glycol
Thermal conductivity, freezing point are high, corrosivity the advantages of, for LNG vaporization device provide stabilization heat and ensure system normal operation.
System Working Principle：
The low temperature river in river is pumped into charge air cooler by outer cooling pump by river house steward and stop valve, and charge air cooler utilizes internal combustion engine
Generation waste heat heating low temperature river, be heated after river enter smoke evacuation water jacket, river discharge fume water jacket in again by
High-temperature tail gas are heated, and by ethylene glycol heat exchanger, after heat is changed away, river is changed the high temperature river after concurrent heating by ethylene glycol
The discharge outlet of hot device is discharged, and the ethylene glycol after heat absorption provides heat for LNG vaporization device, after by liquefied natural gas vaporization, is sent
Enter internal combustion engine to be burnt.
Notable beneficial effect of the invention is：
（1）The waste heat that internal combustion engine is produced is transformed into low temperature river and worked as by the present invention using the charge air cooler being generally used in automobile
In, it is ensured that while internal combustion engine optimum working temperature, by the use of internal combustion engine produce waste heat as LNG vaporization device supplying heat source
One of.
（2）Present invention design smoke evacuation jacket structure for water, using the high-temperature tail gas of internal combustion engine generation to the river in smoke evacuation water jacket
Carry out concurrent heating, it is ensured that the enough heats of river are supplied to LNG vaporization device, vaporizer is stably worked long hours.
（3）The advantages of present invention utilizes ethylene glycol heat exchanger, the outstanding thermal conductivity of ethylene glycol, freezing point high, corrosivity, be
LNG vaporization device provides stabilization heat and ensures the normal operation of system.
