Description
Technical field
The present invention relates to a kind of fishery vessel liquefied natural gas.It is more particularly to a kind of to ensure that cryogenic liquid gas fuel is excellent
The multi-joint gasification system of fishery vessel liquefied natural gas of matter gasification.
Background technology
Shipping industry and five big fishery are the important components of marine economy, and the oil of increasingly depleted and increasingly tight
Weight pollution oneself turn into restriction Shipping industry and five big Fisheries Developments bottleneck.It is strict with International Maritime Organization (IMO)
Regulation, the emission control waters in ECA Europe will drop to 0.1% to sulfide emission limit value from 2015 from present 1%；
From the year two thousand twenty, global range ship sulfide emission limit value will drop to 0.5% from present 4.5%.Therefore must be as early as possible
Develop the substitute fuel of low-sulfur and use the technology of this fuel, just adapt to the standard that the world is prescribed a time limit, limit is arranged.And price is just
Preferably, environment affinity is strong, and the natural gas of abundance arises at the historic moment.Oil product fuel cost is significantly increased in recent years, make sea-freight and
Fishery fishes for profitless, and due to fuel cost, oneself accounts for the 65% of totle drilling cost, and atrophy phenomenon is presented in the two industries, simultaneously
The order for being inconjunction with shipbuilding industry is greatly decreased, Metallurgy Industry loss, the underproduction of digging up mine, the industry atrophy such as coke, refractory material, causes whole
Individual system is absorbed in vicious circle.Dog-eat-dog, fishery dispute, environmental degradation, resource exhaustion, cost rise, harsh regulation is 21
The complex situations that century sea fishery economic development must be faced.The Chinese government is protection national industry, maintains economic stability, often
Year transfers more than 200 hundred million yuan of fuel allowance to fishery is fished for；To recover ecological, throw stream seedling to sea every year, these behaves without
Doubt and add financial burden.It is investigated that bunker oil is one of origin cause of formation of ocean water body and atmosphere pollution.Into 21 century all kinds of dirts
Contaminating and excessively capturing oneself causes China coast aquatic organism drastically to reduce, and the current wild fishes and shrimps amount of inshore fishing die-offs, and fishes and shrimps individual reduces,
Cultivate fishery contaminated serious.Carbon behavior is made due to the mankind, facilitates climate warming, causes Changes in weather variable, the condition of a disaster takes place frequently.
The mankind are declared in the natural revenge to the mankind must change present life pattern and positive exploration, start the Nature is full of
The mode of production of affinity.The current fishery vessel of China recoverable amount on the regular payroll is 106.66 ten thousand, and the total market size is on more than 200 ten thousand left sides
The right side, accounts for 1/3rd of World Ship total amount, wherein large-scale fishing cruiser on the regular payroll is just up to 69.3 ten thousand, whole ship general power on the regular payroll is about
More than 1600 ten thousand kilowatts, about 8,000,000 tons of diesel oil of year consumption, about 25,000,000 tons of CO2 emission.China's fishing boat quantity and tonnage are occupied
The first in the world, fishery practitioner ranks first in the world, and amount of fishing ranks first in the world, but China's fisher and fishery instrument equipment level falls
Afterwards, with world's gap up to 30 years.In the large consumption spending of fishing boat fuel cost oneself account for more than 65%, and relative low price
Natural gas, with its relatively small number of pollution contribution, is aided with the combustion in IC engine technology of relative maturity, is applied to fishery vessel and starts
Machine field can reduce fuel cost 20%~25%, and the sulphur of pollutant emission reduces 100%, and carbon monoxide reduces by 95%, nitrogen
Oxide reduce 85%, suspended particulate substance reduce 70%~100%, carbon dioxide reduce 20%~25%, using natural gas without
Doubt and the bottleneck for maritime foreign economic development of fighting each other is produced into important function.The Chinese government pay much attention to marine fishery resources development and
It is stable, the policies and regulations for promoting sea fishery economic development are specially worked out, to manufacturing large-scale ocean fishing vessel and standardization fishing boat
Give 30% subsidy, the previous work of corresponding subsidies granted for policy considerations also is being done to fishing boat on natural gas clean energy resource.LNG is low
Geothermal liquid fuel, must gasify before, and be limited by capacity of vessel, and gasifier must accomplish miniaturization and high efficiency.

Low temperature resistant, resistance to saline solution, the electrolysis copper pipe of electrocorrosion-resisting must be then used when water, otherwise stainless steel infusion pipeline will be short-term
Internal cause galvano-cautery causes leakage, and breeds disaster.2) multi-joint gasification system device does not employ former fishery vessel engine cool system
The cooling water of system, but cold and hot exchange is directly carried out using the recirculated water of powerful outer circulation water system, thus prevent to adopt
The non-constant engine power performance brought of engine operating temperature, economy, stationarity is caused to become with engine cool recirculated water
Change, recirculated water accidental release can be avoided to cause water shortage, embrace cylinder, the hidden danger shut down again.3) at the same using advanced control system with
When perceive fluid reservoir tolerance, air pressure, temperature and change of gas condition, make LNG gasification work it is safer.
2nd, it is reliable：Air, solar energy, water, the multi-joint gasification installation of electrical heating change LNG ship oceangoing ship and use water-bath or list merely
It is pure to bathe gasifier using empty, in seasons such as late autumn, winter, early springs because environment temperature is low, cause gasifier to freeze, it is impossible to continuously just
What is often worked covers end, makes LNG gasification work more reliable.
3rd, it is economical：Air, solar energy, water, the multi-joint gasification installation of electrical heating utilize available each in environment as far as possible
Class heat energy goes to complete the cold and hot exchange of LNG gasification；Multi-joint gasification installation can use air or water-bath gasification installation significantly more merely simultaneously
Space-consuming is reduced, makes LNG gasification work more economical.
4th, it is advanced：The signals such as tolerance, air pressure, temperature, makings reach console and navigation ECU using radio transmitting device,
And the LNG energy storage of fishery vessel, energy supply, burning, security protection system are carried out remotely to determine using the Big Dipper, GPRS dual mode satellites
Position, communication, office management and control, therefore top standard is at home and abroad in using the LNG gasification device of this technology at present.
