Description
Technical field
This utility model relates to a kind of one noise reducing exhaust device peculiar to vessel.
Background technology
Main exhaust outlet on current most of boats and ships is even essentially all and first connects 90 degree of elbow bends reconnection exhaust expansion bellowses, and in view of the impact of exhaust back pressure, the most also can be enlarged to a specification at corrugated tube exit exhaustor latus rectum, the installing space thus causing 90 degree of elbow bends strengthens, and often on spitkit, engine space is not have the highest installing space.The dilatation blood pressure lowering of the noise elimination cavity of the acoustic filter simultaneously installed additional causes again the increasing of acoustic filter external diameter to be twice left and right, has the most more gone out an individual difficult problem for in-site installation.
Present stage result of the above problems mainly has an individual scheme:
One is corrugated tube to move position install to host horizontal, and main frame supercharger outlet directly connects with 90 degree of elbows, installs flexible suspension near 90 degree of elbows additional simultaneously, then certain fragment position later installs acoustic filter.
Another kind is to cut corrugated tube, reduces its height, and to meet the setting height(from bottom) of 90 degree of elbows, certain fragment position the most later installs acoustic filter.
Above-mentioned two method all cannot effectively solve problem.The main frame supercharger outlet of the first scheme and 90 degree of elbows directly connect and may result in supercharger damage, cause series of problems；First scheme is that this method has certain risk to solve this problem in the cost to reduce corrugated tube effectiveness.So, above-mentioned two method all cannot effectively solve problem, and all can not meet installation exhaustor and the requirement of acoustic filter under conditions of narrow and small cabin, topside aerofluxus.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, it is provided that a kind of reasonable in design, simple in construction, take up room little, with low cost, easy for installation by aerofluxus and the one noise reducing exhaust device peculiar to vessel being integrated in one of eliminating the noise.
The technical scheme is that this utility model of this utility model includes breather and muffler plate group, described breather is arranged in the engine space of hull, one end of described breather is provided with air inlet, the other end is provided with gas outlet, described air inlet is connected with the main exhaust corrugated tube of boats and ships, described gas outlet is connected with the outboard air vent of boats and ships, and described muffler plate group is arranged on the stage casing within described breather, and described muffler plate group forms noise elimination cavity with the stage casing, inside of described breather.
Described muffler plate group includes that adaptation is inclined at the first muffler plate within described breather and the second muffler plate respectively, described first muffler plate is at an angle to each other with the length direction of described breather with the length direction of described second muffler plate, forms described noise elimination cavity between described first muffler plate and described second muffler plate.
The length direction of described first muffler plate and described second muffler plate length direction with described breather respectively becomes 30 degree of angles.
Being evenly arranged with the first sound attenuation hole on described first muffler plate, described second muffler plate is evenly arranged with the second sound attenuation hole, the diameter of described first sound attenuation hole is more than the diameter of described second sound attenuation hole.
Described air inlet and described gas outlet are arranged at the lower surface of described breather, described breather correspond to be provided with cambered surface on the both ends of described air inlet and described gas outlet.
The beneficial effects of the utility model are: in this utility model, owing to being provided with the first muffler plate and the second muffler plate in breather inner inclination, and form noise elimination cavity between the first muffler plate and the second muffler plate, so aerofluxus can be integrated in one by this utility model with noise elimination noise reduction；
In this utility model, the air inlet/outlet of breather is arranged on its lower surface, so its air inlet all need not install 90 degree of elbows additional with the connection of external exhaust gas corrugated tube and the connection of its gas outlet and outside outboard air vent, it is all to be inclined in breather due to the first muffler plate and the second muffler plate again, so himself volume of breather can arrange less and not affect the work area of muffler plate inside it, the volume making this utility model overall is smaller and more exquisite relative to conventional equipment, takes up room little, easier for installation；
Diameter due to the first sound attenuation hole on the first muffler plate is more than the diameter of the second sound attenuation hole again, so after main frame waste gas first passes through the preliminary noise elimination of the first muffler plate in noise elimination cavity, through the second muffler plate, remaining noise can further be eliminated by the second sound attenuation hole, to reach the noise reduction of standard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, this utility model includes breather 1 and muffler plate group, described breather 1 is arranged on the engine space inwall of hull, one end of described breather 1 is provided with air inlet 11, the other end is provided with gas outlet 12, described air inlet 11 and described gas outlet 12 are arranged at the lower surface of described breather 1, described breather 1 correspond to be provided with cambered surface 14 on the both ends of described air inlet 11 and described gas outlet 12.The main exhaust corrugated tube of described air inlet 11 and boats and ships is joined directly together and connects, the outboard air vent of described gas outlet 12 and boats and ships is joined directly together and connects, described muffler plate group is arranged on the stage casing within described breather 1, and described muffler plate group forms noise elimination cavity 13 with the stage casing, inside of described breather 1.
Described muffler plate group includes that adaptation is inclined at the first muffler plate 2 and the second muffler plate 3 within described breather 1 respectively, described first muffler plate 2 is at an angle to each other with the length direction of described breather with the length direction of described second muffler plate 3, forms described noise elimination cavity 13 between described first muffler plate 2 and described second muffler plate 3.
In this embodiment, the length direction of described first muffler plate 2 and described second muffler plate 3 length direction with described breather 1 respectively becomes 30 degree of angles.Being arranged by slanted angle, the work surface of described first muffler plate 2 and described second muffler plate 3 can reach again maximum working value effect while the inner space of adaptive described breather 1.
Being evenly arranged with the first sound attenuation hole on described first muffler plate 2, described second muffler plate 3 is evenly arranged with the second sound attenuation hole, the diameter of described first sound attenuation hole is more than the diameter of described second sound attenuation hole.The main frame waste gas of boats and ships first passes through the preliminary noise reduction of described first sound attenuation hole on described first muffler plate 2 during by described noise elimination cavity, get rid of through described gas outlet 12 again after further noise reduction by described second sound attenuation hole on described second muffler plate 3 again so that the exhausting and denoising of boats and ships can be issued to comfort standard in effect of the present utility model.
Depending on the body size of described breather 1 actual size according to marine main engine cabin, the actual size that the size of described first muffler plate 2 and described second muffler plate 3 also is able to according to described breather 1 body is determined.
This utility model is applicable to marine main engine aerofluxus and noise reduction field.
