Description
Technical field
This utility model is related to ship power system exhaust equipment, refers specifically to one kind environmental protection suitable for ship gas extraction system
Type ship wet type muffler.
Background technology
The gas extraction system of modern ships is generally divided into underwater exhaust, topside aerofluxuss, chimney aerofluxuss and tail part exhaust, and the country sets
The exhaust mode that the barge and public affair ship of meter are more generally adopted is underwater exhaust and topside aerofluxuss, and chimney aerofluxuss are large-scale
Using more on ship such as merchant ship；Tail part exhaust mode in the spitkit of hydraulic jet propulsion, also has minority propeller mostly
The ship of propulsion adopts tail part exhaust mode, but the cost paid is the gross weight increase of gas extraction system, causes the speed of a ship or plane of ship
There is certain reduction.Above-mentioned various exhaust mode generally existing exhaust noises, while the presence in boat diesel engine aerofluxuss is a large amount of
SOx, air is polluted in addition, above-mentioned various conventional exhaust modes cannot also meet the required comfortableness of barge
And high performance requirements.
The content of the invention
The purpose of this utility model seek to reduce ship gas extraction system exhaust noise and diesel engine operating produced by
Smog, the content for reducing the SOx in boat diesel engine aerofluxuss provide a kind of environmental protection type ship wet type muffler.
For achieving the above object, the environmental protection type ship wet type muffler designed by this utility model, its special character
It is：Including deafener body, the deafener chamber body is divided into the sea water chamber and gas-liquid arranged up and down by water-distributing device
Hybrid chamber, the sea water chamber are connected with diesel coolant outlet pipe, and the gas-liquid mixed chamber is connected with exhaust bypass pipe；It is described
Deafener body is inserted into being provided with Diesel Engine Exhaust Pipe, and described Diesel Engine Exhaust Pipe one end is through sea water chamber and gas-liquid mixed chamber
Directly connect, the Diesel Engine Exhaust Pipe other end is stretched out deafener body and connected with diesel exhaust gas mouth by flange-interface
Connect.
Further, water-distributing device structure annular in shape, described Diesel Engine Exhaust Pipe one end is through the circulus
Centre bore, the circulus have been uniformly distributed circumferentially some spouts.As such, it is possible to the sea water of sea water intracavity is made, uniformly
The flue gas that gas-liquid mixed chamber is sprayed into Diesel Engine Exhaust Pipe is sufficiently mixed reaction.
Further, some notch settings have three circles, and the spout on adjacent turn circumferentially misplaces arrangement.
Principle of the present utility model is：In running, sea water Jing cooling water pumps, after cooling main frame, inject this to ship
The sea water intracavity of utility model；Diesel Engine Exhaust Pipe is connected with gas-liquid mixed chamber, and flue gas is entered gas-liquid mixed chamber；Sea water intracavity
Sea water Jing water-distributing devices spray into gas-liquid mixed intracavity, generally in alkalescence, its main component is chloride and sulfate to sea water,
Containing substantial amounts of soluble salt and a certain amount of soluble carbonate salt, the flue gas and sea water generation chemical desulfurization of Diesel Engine Exhaust Pipe is anti-
Should, main chemical reactions are as follows：
SO2+H2O→H2SO3
H2SO3→H++HSO3 -, HSO3 -→H++SO3 2-
SO3 2-+1/2O2→SO4 2-
Flue gas is carried out to mix with fresh seawater when the sea water after desulfurization process discharges hull, the marine site of ship running
It is exactly a natural large-scale Aeration tank, the dissolved oxygen being rich in sea water makes rapidly labile sulfite oxidation into stable sulfur
Hydrochlorate.On the other hand, gas-liquid mixed chamber Media density and velocity of sound Jing after water-distributing device water spray there occurs change, that is, cause acoustic impedance
Change, and make sound wave occur reflection；When two-phase medium is mixed, there is friction, make energy loss, eliminate a part of noise.
The utility model has the advantage of：The natural surroundingses navigated by water on ocean using ship, carry out desulfurization using sea water, save
The raw material gone needed for wet scrubbing, and washed product can enter ocean Jing after processing, its investment and operating cost are relatively
It is low, and using sea water as absorbent, desulfuration efficiency is high, energy-conserving and environment-protective；Simultaneously using water-distributing device water spray make Media density and
The velocity of sound changes, and then eliminates a part of noise, reaches the effect of noise reduction.
