Description
Technical field
The present invention relates to a kind of fishery vessel that rock gas is fuel of take.Particularly relate to a kind of anti-spike recycling system of fishery vessel storage control prison that adopts gas fuel.
Background technique
Shipping industry and fish for the important component part that fishery is marine economy, and day by day exhausted oil and day by day serious pollution oneself become the bottleneck that restriction transport service and fishery develop.Along with the strict regulations of International Maritime Organization (IMO), the emission control waters in ECA Europe will drop to 0.1% from present 1% to sulfide emission limit value from 2015; From the year two thousand twenty, global range boats and ships sulfide emission limit value will drop to 0.5% from present 4.5%.Therefore must develop as early as possible the substitute fuel of low-sulfur and use the technology of this fuel, could adapt to international in limited time, the standard of the row of limit.And low price, environment affinity is strong, and the abundant rock gas of originating arises at the historic moment.The significantly increase of oil product fuel cost in recent years, make sea-freight and fishery fish for profitless, due to fuel cost, oneself accounts for 65% of overall cost, these two industries all present atrophy phenomenon, the order that is simultaneously inconjunction with shipbuilding industry significantly reduces, Metallurgy Industry loss, the mining underproduction, the atrophy of the industry such as coke, refractory material, causes whole system to be absorbed in vicious circle.Dog-eat-dog, fishery dispute, environmental deterioration, resource exhaustion, cost raises, and rules are harsh is the complex situations that 21 century sea fishery economic development must be faced.The Chinese government, for protection national industry, maintains economic stability, every year to fishing for the fishery fuel allowance of more than 200 hundred million yuan of transferring; For recovering ecological, to sea, throw every year stream seedling, these behaves have increased financial burden undoubtedly.It is investigated that bunker oil is one of origin cause of formation of ocean water body and pollution of atmosphere.Enter all kinds of pollutions of 21 century and excessively capture oneself and cause China coast aquatic organism sharply to reduce, the wild fishes and shrimps amount of inshore fishing die-offs at present, and fishes and shrimps individuality reduces, and cultivation fishery is contaminated serious.Due to the mankind's the carbon behavior of making, facilitate climate warming, cause changes of weather variable, the condition of a disaster takes place frequently.Nature is being declared the mankind to the mankind's revenge and must changed present life pattern and positive exploration, start the mode of production that nature is full of to affinity.The current fishery vessel of China recoverable amount on the regular payroll is 106.56 ten thousand, the total market size is more than 200 ten thousand left and right, account for 1/3rd of World Ship total amount, wherein large-scale fishing cruiser on the regular payroll just reaches 69.3 ten thousand, approximately more than 1,600 ten thousand kilowatts of whole ship total outputs on the regular payroll, year consumes approximately 8,000,000 tons of diesel oil, approximately 2,500 ten thousand tons of CO2 emission.China's fishing boat quantity and tonnage rank first in the world, and fishery practitioner rank first in the world, and rank first in the world ，Dan China fisher and fishery instrument equipment level of amount of fishing falls behind ，Yu world gap and reaches 30 years.In the large consumption of fishing boat spending fuel cost oneself account for more than 65%, and the rock gas of relative low price, with its relatively less pollution contribution, be aided with relatively ripe combustion in IC engine technology, be applied to fishery vessel engine art and fuel cost can be reduced to 20%～25%, the sulphur of pollutant emission reduces 100%, carbon monoxide reduces 95%, nitrogen oxide reduces 85%, suspending particulate matter reduces 70%～100%, carbon dioxide reduces 20%～25%, adopts rock gas undoubtedly the bottleneck of the maritime foreign economic development of air exercise to be produced to important function.The Chinese government pays much attention to the development and stabilization of marine fishery resources, the policies and regulations that promote sea fishery economic development have been worked out specially, to manufacturing large-scale ocean fishing vessel and standardization fishing boat gives 30% subsidy, fishing boat on rock gas clean energy resource is also being done to the previous work of corresponding subsidies granted for policy considerations.
LNG(LNG Liquefied natural gas-Liquefied Natural Gas), be a kind ofly to take liquid methane and be main fuel, methane (CH
4); Containing a carbon atom and 4 hydrogen atoms, compare and can be considered low-carbon (LC) fuel with other hydrocarbon fuels; This fuel is prepared under ℃ condition of low temperature-161.5, is in a liquid state, and gas liquid ratio 625:1; Its greenhouse gases effect only has 1/2 of coal, is 40% of oil, and sulfur compound not,, without suspending particulate matter, is a kind of efficient, low pollution fuel of novelty after burning completely.
CNG(compressed natural gas-Compressed Natural Gas) be a kind of squeezed state methane of normal temperature 20Mpa high pressure, this fuel is prepared under 250kg/ ㎡ condition, is high-pressure gaseous, and other conditions are all methane.
Because above-mentioned rock gas is all the fuel of methane, just store status is different, also can by both qualitative be same sex differential mode fuel.
Oneself is very ripe for current single fuel natural gas combustion in IC engine technology, and all oneself is accepted extensively by society in the application of its product in vehicle and the distribution energy, generating.Why to use bifuel system? first sea situation is complicated, and wind and cloud is changeable, and river course is narrow, bridges and culverts, harbour and hydrologic condition are different, once internal-combustion engine breaks down, the boats and ships that run out of steam will drift with the tide, uncontrollable, its consequence is hardly imaginable, so will consider stand-by power fuel; Have LNG as low temp fuel, CNG is as fuel under high pressure again, and ANG is as adsorbed fuel, and accumulating all has specific characteristics, and therefore from the energy safety of supply guarantee aspect, also will consider stand-by power source; Separately from internal combustion engine Combustion angle, consider, natural gas fired temperature is higher than fuel oil 30%, and velocity of combustion again more oily combustion is slow, and large cylinder diameter ignition effectiveness is poor; From infusion of financial resources, carry out " energy-saving and emission-reduction " technical innovation angle, from the viewpoint of technical innovation cycle and investment in technological transformation payoff period etc., also need---mixed combusting technology and double fuel product peculiar to vessel safer, that be suitable for.
The pollution that fishery vessel exhaust emissions causes inland river, maritime waters is at present the weak link of China's environmental improvement.China's fishery vessel technical equipment falls behind, and especially high energy consumption product is also in a large amount of uses, and this directly jeopardizes fisherman's production and quality of life in the situation that oil price is soaring.Fishery resources are exhausted, and fishing boat operating cost is surging, produce and expand the lifting that funds shortage is all restricting China's fishery vessel technology, affect the development of shipbuilding industry simultaneously; Add day by day harsh Abgasgesetz, all directly affect the normal development of national economy.
