Description of drawings
Fig. 1 is the structural representation of the utility model embodiment's marine main engine emission-control equipment.
Wherein, description of reference numerals is as follows: main frame 1, exhaust header 2, outlet pipe 3, control valve 4, control panel 5, exhaust manifold 6, pressurized machine 7 and exhaust boiler 8.
Embodiment
In order to further specify principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.See also Fig. 1, the utility model provides a kind of marine main engine emission-control equipment, this marine main engine emission-control equipment is in order to process the waste gas in the exhaust header 2 that connects main frame 1, comprise a control valve 4 and a bypass arm 3, can also comprise at least one pressurized machine 7, an exhaust manifold 6, a control panel 5 and an exhaust boiler 8.
Main frame 1, main frame 1 provides power in boats and ships, owing to be to produce power by the burning fuel oil, so in operation process, need to suck large quantity of air, and produce simultaneously large quantity of exhaust gas.
Exhaust header 2, exhaust header 2 connects main frame 1, and the effect of exhaust header 2 is the waste gas that main frame produces to be put together with convenient process.Because the volume of the main frame 1 of large ship is very large, independent pipeline waste gas extremely bothers nor reality, so by exhaust header 2 all waste gas is put together processing, it is also convenient not only to reduce trouble but also the recycling processed.
Bypass arm 3, an end of bypass arm 3 connects exhaust header 2.
Control valve 4, control valve 4 is connected on the other end of bypass arm 3, control valve 4 is used for controlling the switching degree of bypass arm 3, because it all is to connect exhaust header 2 that pressurized machine 7 is connected with the bypass arm, and the switching of control valve 4 affects the waste gas intake of bypass arm 3, thereby affects the waste gas intake of pressurized machine 7.
Control panel 5, control panel 5 connects control valve 4, and in order to control the switching of control valve 4, control panel 5 is according to the switching of the rotational speed regulation control valve 4 of pressurized machine 7.Because pressurized machine 7 comes fresh air is pressurizeed by the rotation of the drive pressurized machine 7 of the waste gas that passes into, like this when the exhausted air quantity that passes into is excessive, the rotating speed of pressurized machine 7 will be too fast, thereby the pressure that causes fresh air to be added is excessive, can cause like this oil consumption of main frame 1 to increase.And otherwise the exhausted air quantity that passes into then can cause fresh air pressurized too small when too small, does not reach suitable pressure, thereby affects the work of main frame 1.Control panel 5 can judge that by the rotating speed of pressurized machine 7 exhausted air quantity that pressurized machine passes into is too much or very few, thereby the switching degree of corresponding adjusting control valve is regulated the exhausted air quantity that passes in the bypass arm 3, and the exhausted air quantity that passes into of pressurized machine 7 also can respective change like this.For example, it is too high that control panel 5 detects the rotating speed of pressurized machine 7, and control panel 5 control control valves 4 are opened more, and the exhausted air quantity that then passes in the bypass arm 3 increases, and the exhausted air quantity that pressurized machine 7 passes into reduces, thereby recover normal so that the rotating speed of pressurized machine 7 reduces.Such regulation and control are so that the proper operation scope increase of pressurized machine 7, and the load of main frame 1 is often to change, this exhausted air quantity that causes producing also constantly changes, like this than the situation that does not have control valve 4 and control panel 5, so main frame 1 is because pressurized machine 7 can guarantee in very large range also that when load variations peak efficiency can reduce a lot of energy consumptions.
Exhaust manifold 6, exhaust manifold 6 connects control valve 4, and exhaust manifold 6 puts together the waste gas of pressurized machine 7 and outlet pipe 3 shuntings again, so that follow-up processing.
