Description
Technical field
The present invention relates to engine of boat and ship tail gas disposal technique fields, and in particular to a kind of ship with check valve starts
Tail gas and device of air.
Background technology
Shipping because have the advantages that can loading object amount is big, safety, operation costs are low etc., be used as economy globalization for a long time
The mainstream means of transportation of change period international trade.Shipping share is up to 90% and respectively in the volume of trade in European Union, the U.S. at present
80%.China's shipping industry is also quickly grown in recent years, and the water route volume of goods transported and volume of the circular flow account for 11.4% He of multi-transportation amount respectively
45.6%, and the foreign trade on 90% is undertaken, have become harbour big country and shipping big country.However the high development of Shipping is given
Atmospheric environment brings pressure.For most ship using diesel engine as power source, main fuel is the higher mink cell focus of sulfur content,
And wherein Large ocean going vessels are often miscellaneous oily for fuel with poor quality, therefore shared by sulfide in the tail gas of boat diesel engine discharge
Ratio very from.Pollutant has accounted for 10% or so of whole world pollutant total displacement in ship tail gas at present, wherein being counted according to Norway
Data show, discharge the amount of sulfide boat diesel engine year up on 6,000,000 tons, account for the 4% of global total release, it is contemplated that the year two thousand twenty
The discharge capacity amount of increase of sulfur dioxide can be more than 40%, and main pernicious gas NOx and SOx in tail gas etc. is more next to the harm of environment
It is more serious.International Maritime Organization IMO has formulated stringent emission regulation thus, and phase III emission regulation started in 2016
Implement.In view of the seriousness and urgency of ship sulphur emissions problem, countries in the world and area tissue have carried out ship discharge in succession
The relevant technologies that object is honoured an agreement, ship emission control technique are increasingly becoming research hotspot.
In order to cope with stringent emission regulation, ship tail gas cannot be directly discharged in air, need to install exhaust gas and gas additional
Device and processing unit.It is counted according to Environmental Protection Agency, the research of flue gas desulfurization starts from early 20th century, and countries in the world research and development use
Flue gas desulfurization technique up to more than 200 kinds, whether add the dry and wet form of water and desulfurization product that can be divided by sweetening process：Wet method, half
Dry method and dry method three classes.Current main-stream technique mainly has gypsum method flue gas desulfurization, the flue gas desulfurization of rotary spraying and drying method and seawater
Doctor treatment etc..Power plant on ship is other than host, also more power plants such as subsidiary engine and boiler.Due to ship overhead
Between it is limited, it is impossible to the mating a set of processing equipment of each power plant is individually for, so needing the exhaust gas of a plurality of discharge duct
Uniformly collect processing, the stable operation of exhaust gas processing device needs the remittance of a lot of platform engines of efficient process and asks
Topic.
In the prior art, about marine diesel tail gas and gas technology mainly have：
A kind of gas collecting apparatus for ship tail gas desulphurization system of Patent No. " CN205991197U ", discloses one kind
Exhaust gas gas collecting apparatus, device at least two conduit air inlet, the end of each conduit air inlet set that there are one go deep into valve inner
Guide wire.But the device does not have independent voltage stabilizing buffer unit, operating mode that can not switch, and prevents gas backflow effect limited.
Patent " CN106629629A " and gas unit and apply its sulfuric acid preparation system, devise a kind of and gas unit
And its sulfuric acid preparation system is applied, including and feed channel and air supply device.And intake valve and gas are provided in feed channel
Valve and outlet valve air supply device are connected to simultaneously feed channel and for providing air for follow up device, intake valve is for controlling
Air enters and feed channel, and air valve is used to control and the path of feed channel inner air flow, and outlet valve is used to prevent and tracheae
Air outflow in road.But the system pertains only to sulfuric acid preparation system technical field, it is impossible to be used in ship tail gas treatment technology is led
Domain.
Main problem existing for marine diesel tail gas and gas technology is back pressure, refluence and leakage at present, and back pressure height can be led
Engine consumption is caused to increase, stabilization of equipment performance declines.Refluence can cause pipeline enclosure to be collaborated, the combustion apparatus high-temp waste gas to have worked
In the equipment not worked into other that cannot collaborate.The pressure oscillation of engine exhaust is very big under high temperature, and common valve body exists
Can be deformed under prolonged thermal shock causes to reveal, and then leakproofness declines.Simultaneously device of air technology is difficult to pacify to existing exhaust gas
Reach above-mentioned requirements simultaneously in full reliability and precision.
