Abstract
The utility model discloses a kind of boat diesel engine pressurized air secondary load device, the engine chamber that this device comprises diesel engine body part and the turbosupercharger be made up of exhaust gas turbine, rotor shaft and compressor turbine, also comprise the air loader being connected described turbosupercharger by suction tude, described air loader comprises three-way valve, three-way valve control box and gas holder, three-way valve control box described in described three-way valve is connected by signaling line, described gas holder connects the lower openings of described three-way valve.The utility model has the advantages that: can required air inflow when marine diesel engine loads suddenly be supplemented in good time and booster action be played to the turbosupercharger of unit, thus improve because air inlet is not enough, insufficient caused a large amount of carbon smoke exhaust situations of burning when boats and ships load, reduction carbon smoke exhaust is to the pollution of ocean environment.
Description
Technical field
The utility model relates to a kind of deceleration loading device, and in particular, the utility model relates to a kind of boat diesel engine pressurized air secondary load device.
Background technique
Increasingly serious Marine Environmental Problems is more and more subject to people's attention; the exhaust emissions of boat diesel engine then plays key player in marine environmental pollution problem; especially when coastal waters boats and ships load; because air inlet is not enough; burn insufficient; often cause a large amount of carbon smoke exhaust, add the particulate matter in paralic environment.
Those skilled in the art are known, adopt the method increasing amount of charge air can reduce the carbon smoke exhaust of diesel engine when boats and ships load, but although the method can obtain certain effect, the result that NOx emission exhaust back pressure may being brought also to increase cause because of oxygen-enriched combusting under problem and steady working condition increases.
Summary of the invention
The purpose of this utility model solves the problem exactly, and provides a kind of boat diesel engine pressurized air secondary load device for this reason, thus the carbon smoke exhaust caused because air inlet is not enough when reducing boat diesel engine loading is to the pollution of ocean environment.
Technical solution of the present utility model is:
A kind of boat diesel engine pressurized air secondary load device, the engine chamber comprising diesel engine body part and the turbosupercharger be made up of exhaust gas turbine, rotor shaft and compressor turbine, also comprise the air loader being connected described turbosupercharger by suction tude, described air loader comprises three-way valve, three-way valve control box and gas holder, three-way valve control box described in described three-way valve is connected by signaling line, described gas holder connects the lower openings of described three-way valve.
Boat diesel engine pressurized air secondary load device of the present utility model, overcome many defects of prior art, its beneficial effect is embodied in following several respects:
(1) air inflow required when marine diesel engine loads suddenly can be supplemented in good time, and air inflow when can meet steady working condition by natural inflow system;
(2) the sluggish and problem that the not enough problem of air inlet that is that cause and unit carbon smoke exhaust amount increase of diesel engine unexpected Loading opportunity group turbosupercharger response can be solved;
(3) booster action can be played to the turbosupercharger of unit, thus reduce the exhaust gas turbine carbon distribution caused more slowly because of turbo charger speed when loading;
(4) can improve because air inlet is not enough, insufficient caused a large amount of carbon smoke exhaust situations of burning when boats and ships load, thus reduce when boats and ships load suddenly because of the pollution of diesel engine carbon black discharge to ocean environment.
Accompanying drawing explanation
Accompanying drawing is system diagram of the present utility model.
Mark in figure: 1-engine chamber, 2-outlet pipe, 3-exhaust gas turbine, 4-rotor shaft, 5-compressor turbine, 6-suction tude, 7-three-way valve control box, 8-signaling line, 9-three-way valve, 10-gas holder.
Embodiment
In order to make the utility model more easily be understood, below in conjunction with drawings and Examples, the technical solution of the utility model is further described:
See accompanying drawing, boat diesel engine pressurized air secondary load device of the present utility model, the engine chamber 1 comprising diesel engine body part and the turbosupercharger be made up of exhaust gas turbine 3, rotor shaft 4 and compressor turbine 5, also comprise the air loader being connected described turbosupercharger by suction tude 6, described air loader comprises three-way valve 9, three-way valve control box 7 and gas holder 10.
Exhaust gas turbine 3 in described turbosupercharger, its one end connects described engine chamber 1 by outlet pipe 2, and its other end connects compressor turbine 5 by rotor shaft 4;
Three-way valve 9 in described air loader is arranged in suction tude 6, and the compressor turbine 5 connected by described suction tude 6 in described turbosupercharger, gas holder 10 described in described three-way valve 9 connects with its underpart opening also passes through signaling line 8 connecting tee valve control box 7, and the spool action of described three-way valve 9 is controlled by described three-way valve control box 7.
Working principle of the present utility model is:
When unit load loading amplitude exceedes certain value, described signaling line 8 is passed through by spool breakdown action signal transmission to three-way valve 9 by described three-way valve control box 7, supplement air inlet to be supplied by the gas holder 10 connecting described three-way valve 9 lower openings, thus solve the problem of air inlet deficiency;
When unit load fluctuation does not exceed setting limit value, by described three-way valve control box 7 by described signaling line 8 by spool closing motion signal transmission to three-way valve 9, still adopt former intake method, complete air inlet by natural aspiration and supply.
Boat diesel engine pressurized air secondary load device of the present utility model, its vibrational power flow is simple, refining, after diesel engine realizes being connected, the carbon smoke exhaust caused because air inlet is not enough when boat diesel engine loads can be effectively reduced, and the situation that the NOx emission caused because of oxygen-enriched combusting under can avoiding exhaust back pressure increase problem and steady working condition increases, thus reduce the pollution to ocean environment.
Below schematically describe the utility model in conjunction with the accompanying drawings and embodiments, this description is not restricted.Those skilled in the art will be understood that in actual applications, and constituted mode of the present utility model some likely occurs as the case may be and changes, and under enlightenment of the present utility model, other staff also may make the design similar to the utility model.Special needs to be pointed out is, only otherwise depart from design aim of the present utility model, all apparent changes and have equivalent similar Design of replacing, all should belong to protection domain of the present utility model.
