Description
Technical field
The utility model relates to a kind of marine auxiliary machinery exhaust system, relates in particular to a kind of novel ship auxiliary exhaust range.
Background technology
In traditional ship design, the waste gas of general subsidiary engine directly is discharged in the atmosphere, contains a large amount of heat energy in the subsidiary engine waste gas and is wasted.In the modernization large ship, general main and auxiliaries all is a heavy oil combustion.The viscosity ratio of heavy oil is bigger, must could use the transportation by lighter pump to lighter and offer main and auxiliary machine burning through after the heating.All be provided with fuel oil waste gas packaged boiler on the general boats and ships, generation steam is heated in the exhaust that (main frame normal operation) can make full use of main frame when this boiler normally navigated by water at boats and ships, supplies with the heavy oil heating and other need the place of steam.The burner section that fuel oil waste gas packaged boiler also can carry through it produces steam.But during at lowsteaming, engine speed is lower at boats and ships for the method for this steam, and the exhaust gas temperature of generation is low, and discharge capacity is few, and the quantity of steam that the main exhaust heating produces is not enough, needs burner section to heat and remedies; During ship berthing, main frame is out-of-run, if need steam on the ship this moment, the burner section that can only lean on fuel oil waste gas packaged boiler to carry produces steam, and the burner section consumption of fuel of fuel oil waste gas packaged boiler is very large.Therefore how making full use of the heat energy in the subsidiary engine waste gas, is a research content in our the modernized ship design.
The utility model content
It is high that the present invention has overcome above-mentioned boats and ships fuel consumption when low speed driving and stop, and exhaust emission is serious, shortcomings such as operation cost height; Improved a kind of simple in structure; Low cost of manufacture, the subsidiary engine discharging waste gas is fully utilized, and reduces the fuel oil consumption; Reduce discharging, help the novel ship auxiliary exhaust range of energy savings environmental protection.
Foregoing of the present invention is mainly following through following scheme: a kind of novel ship auxiliary exhaust range; Comprise ship machine subsidiary engine, main frame and boiler, ship machine subsidiary engine is provided with the auxiliary exhaust pipe, and main frame is provided with the main exhaust pipe; The bottom of boiler is provided with the main exhaust import; The boiler middle part is provided with burner section, and the top of boiler is provided with fuel oil freeing pipe and waste gas exhaust pipe, and the auxiliary exhaust pipe is provided with exhaust conversion butterfly valve; Exhaust conversion butterfly valve is provided with subsidiary engine boiler air inlet pipe, and the bottom of boiler is provided with subsidiary engine boiler admission port;
As preferably, the subsidiary engine boiler admission port of the subsidiary engine boiler air inlet pipe of novel ship auxiliary exhaust range and boiler bottom is complementary.
Through above narration: the present invention has advantage: 1, the coupling setting of exhaust conversion butterfly valve, subsidiary engine boiler exhaust pipe and boiler bottom subsidiary engine boiler admission port on the auxiliary exhaust pipe of ship machine subsidiary engine; The waste gas that has great amount of heat energy that subsidiary engine work is produced gets into boiler through exhaust conversion butterfly valve, subsidiary engine boiler exhaust pipe, subsidiary engine boiler admission port; The waste gas that utilizes ship machine subsidiary engine work generation has reduced the main frame fuel consumption for main frame waste gas replenishes; 2, the heat energy that utilizes ship machine subsidiary engine waste gas to carry gets into boiler, assists burner section to produce steam, reduces burner section because of producing the required fuel oil of steam; Reduce the burner section fuel consumption, practiced thrift the energy, reduce ship machine operation cost; Reduce exhaust gas discharging simultaneously, helped environmental protection; 3, the coupling setting of exhaust conversion butterfly valve, subsidiary engine boiler exhaust pipe and boiler bottom subsidiary engine boiler admission port on the auxiliary exhaust pipe of ship machine subsidiary engine; Having solved marine low speed goes and stops the amount of fuel height; Problems such as operation cost is high, and environmental pollution is serious have satisfied user's demand; 4, the utility model is simple in structure, and manufacture craft is simple, low cost of manufacture; Reduce the use cost that marine low speed is gone and stopped, reduced the whole operation of boats and ships use cost, practiced thrift the energy; Reduced discharge amount of exhaust gas; Help reducing environmental pollution, satisfied user's request, help applying.
Description of drawings
Fig. 1 the utility model structural representation;
Fig. 2 the utility model improves the pre-structure scheme drawing.
The specific embodiment
Below in conjunction with embodiment, and combine scheme drawing, technical scheme of the present invention is further specified.
As illustrated in fig. 1 and 2, a kind of novel ship auxiliary exhaust range comprises ship machine subsidiary engine 1, main frame 3 and boiler 5.Ship machine subsidiary engine 1 is provided with auxiliary exhaust pipe 2, is the discharge line of the waste gas of ship machine subsidiary engine 1 work generation.Main frame 3 is provided with main exhaust pipe 4.The bottom of boiler 5 is provided with main exhaust import 6.The setting of main exhaust pipe 4 and main exhaust import 6 is convenient to energy that waste gas that main frame 3 produces carries to boiler 5 heating, promotes the generation of steam, for the boats and ships cruising provides required quantity of steam.Boiler 5 middle parts are provided with burner section 7.The setting of oil burner 7, when marine low speed is gone and stop the amount of required steam can not satisfy boats and ships required in, through oil burner 7 fuel oils, promote boiler 5 to produce steam, required to satisfy boats and ships.The top of boiler 5 is provided with fuel oil freeing pipe 8 and waste gas exhaust pipe 9.The setting of fuel oil freeing pipe 8 and waste gas exhaust pipe 9, the gas that helps in the boiler 5 is discharged.Auxiliary exhaust pipe 2 is provided with exhaust conversion butterfly valve 10.Exhaust conversion butterfly valve 10 is provided with subsidiary engine boiler air inlet pipe 11.The bottom of boiler 5 is provided with subsidiary engine boiler admission port 12.Subsidiary engine boiler air inlet pipe 11 is complementary with the subsidiary engine boiler admission port 12 of boiler 5 bottoms.The coupling setting of exhaust conversion butterfly valve 10, subsidiary engine boiler exhaust pipe 11 and boiler 5 bottom subsidiary engine boiler admission ports 12 on the auxiliary exhaust pipe 2 of ship machine subsidiary engine 1; The waste gas that has great amount of heat energy that 1 work of ship machine subsidiary engine is produced gets into boiler 5 through exhaust conversion butterfly valve 10, subsidiary engine boiler exhaust pipe 11, subsidiary engine boiler admission port 12; The waste gas that utilizes 1 work of ship machine subsidiary engine to produce replenishes for main frame 3 carries out waste gas, has reduced main frame 3 fuel consumption.The heat energy that utilizes ship machine subsidiary engine 1 waste gas to carry gets into boiler 5, assists burner section 7 to produce steam, reduces burner section 7 because of producing the required fuel oil of steam; Reduce burner section 7 fuel consumption, practiced thrift the energy, reduce ship machine operation cost; Reduce exhaust gas discharging simultaneously, helped environmental protection.The coupling setting of exhaust conversion butterfly valve 10, subsidiary engine boiler exhaust pipe 11 and boiler 5 bottom subsidiary engine boiler admission ports 12 on the auxiliary exhaust pipe 2 of ship machine subsidiary engine 1; Having solved marine low speed goes and stops the amount of fuel height; Problems such as operation cost is high, and environmental pollution is serious have satisfied user's demand.
