Embodiment
An embodiment of the present utility model carries out technical finesse to the waste gas that diesel engine is discharged, and is referred to as post-processing technology.
As shown in Figure 1, the scrubbing member comprises: scrubbing container 4, gasotron 5, spraying device 6, moisture trap 7 that from top to bottom order in scrubbing container 4 arranges, be arranged on the outlet pipe 8 on the scrubbing container 4, absorbing agent is transported to the transfer pump 9 of spraying device 6, with the particle fuel filter 10 of scrubbing container 4 internal communication.
The waste gas of discharging from the relief opening of motor or diesel engine 1 enters the outlet pipe 3 of drawing by exhaust-gas turbocharger 2 superchargings, outlet pipe 3 extends into the bottom of scrubbing container 4, make the waste gas of discharging from diesel engine 1 enter scrubbing container 4 at the waste gas streams that outlet pipe 3 forms at a high speed ejection, the waste gas streams that enters scrubbing container 4 bottoms obtains the dilatation deceleration and rises to gasotron 5, waste gas is uniformly distributed in the scrubbing container, and continues to rise by gasotron 5.Transfer pump 9 is transported to spraying device 6 above gasotron 5 with absorbing agent, absorbing agent sprays through spraying device 6 and forms the agent of high density atomization absorption, contact and collide with the waste gas streams generation leggy that rises through gasotron 5, particle in the waste gas streams (PM) and sulfur dioxide (SOX) and other harmful gases are caught, neutralize by vaporific absorbing agent, preferably absorbing agent adopts calcium solution, thus with play sour calcium neutralization after material in the waste gas streams contacts and collides.According to actual needs, absorbing agent also can adopt other suitable material.The mode that preferably spraying device 6 can multilayer arranges that in the present embodiment, spraying device 6 comprises first layer sprayer 6a and second layer sprayer 6b, even the 3rd layer of sprayer also can be set according to circumstances, and each sprayer comprises a plurality of spray heads.After the vaporific absorbing agent that ejects by first layer sprayer 6a absorbs and catches particle and harmful gas in the waste gas streams, waste gas streams continues to rise to second layer sprayer 6b, the vaporific absorbing agent that the particle of slipping through the net on a small quantity wherein and harmful gas are ejected by second layer sprayer 6b continues to catch and absorb, and can make like this absorptivity of harmful gas reach 95%.More than the catching rate of particle of two- layer sprayer 6a and 6b make waste gas reach PM2.5 or following through its fine particle after as above processing, waste gas has at this moment reached emission standard, but has become exhausting air.Contain certain water yield in the exhausting air, gas continue to rise, until enter the moisture trap 7 that is arranged on spraying device 6 tops, with the water yield that will be wherein, namely water droplet is removed, and the gas of removing water droplet enters in the atmosphere by outlet pipe 8.The vaporific absorbing agent that ejects is through after contacting and collide with waste gas, because Action of Gravity Field drops to the bottom of scrubbing container 4 by sedimentation, then flow into particle fuel filter 10 from exhaust port, carry out refuse after being collected and process, absorbing agent is carried out oxygenation process, make the SO that dissolves in seawater
2Be converted into sulphate after oxygenation, and sulphate is the constituent element of seawater, absorbing agent is discharged after so processing.
An embodiment who is used for boats and ships, absorbing agent is seawater.The absorbing agent of processing through oxygenation can be discharged into marine greatly.
Another embodiment of the present utility model controls carbon monoxide (CO), oxynitrides (Nox) that diesel engine produces in burning, is referred to as pretreatment technology.
The oxynitrides (NOX) that motor or diesel engine produce and the principle of carbon monoxide (CO) are, when motor in when work, fuel combustion must be more abundant in the firing chamber, the oxygen that needs is just more, but often in the high-revolving situation of high load, oxygen supply does not catch up with, and the firing chamber just produces the operating mode of High Temperature High Pressure anoxic, and at this moment the gas of discharging just generates oxynitrides (NOX) and carbon monoxide (CO) easily.In order to address this problem, to have taked to be the measures such as oxygen supply increase pressurized machine, but can not deal with problems fully.The utility model adopts the technology that installs spraying device B additional at the intake duct A of diesel engine 1 to control the generation of oxynitrides (NOX) and carbon monoxide (CO) for this reason.
When SCS and DCS respectively the sensor F perception delivery temperature of the sensor E by outlet pipe 3 and motor 1 rise and surpass that predetermined value and engine speed rise and when surpassing predetermined value, just start immediately humidification pump C, in time spray into an amount of water by spraying device B to intake duct A thus, preferably water purification forms spray water.At this moment the firing chamber of diesel engine 1 has in time obtained the increase of replenishing of oxygen and humidity in the situation of High Temperature High Pressure anoxic, again because the gasification heat-absorbing action of water can make the firing chamber reduce certain temperature, after oxygenation, humidification and cooling, a large amount of generations of oxynitrides (NOX) and carbon monoxide (CO) have been blocked.Oxygenation and humidification can in time reduce the discharging of above-mentioned two kinds of harmful gases by supplementing water.
In another embodiment of the present utility model, with the use that combines of above two kinds of technology, make the discharging of marine diesel engine obtain effectively comprehensively control.
The utility model can adopt seawater as absorbing agent, so operating cost is extremely low, promotes the use of easily and is not subjected to resource limitation, does not have secondary pollution.
As shown in Figure 2, schematically show an embodiment's of gasotron 5 structure roughly among Fig. 2, in gasotron 5, be provided with screen cloth, be uniformly distributed into the inside of scrubbing container by the waste gas streams of this screen cloth.
As shown in Figure 3, schematically illustrated spraying device 6 embodiment's structure among Fig. 3 has been arranged a plurality of spray heads in this spraying device 6, and the absorbing agent of transfer pump 9 inputs is ejected from a plurality of spray heads, forms vaporific absorbing agent.
As shown in Figure 4, schematically illustrated moisture trap 7 embodiment's structure among Fig. 4, the exhausting air of process waste gas treatment is removed moisture wherein through moisture trap 7.
Technology of the present utility model not only can be applied in the control of marine internal combustion engine gas emission, also can be applicable to similarly have in the traffic tool and mechanical engineering of exhaust emission pollution situation, for example, offshore oil, exploitation of mineral resources drill platform, sea, seashore diesel power generation unit and diesel powered source.Therefore; protection domain of the present utility model is not limited to the embodiment of specification; for example; gasotron 5, spraying device 6, moisture trap 7; outlet pipe 8; the variety of components number of transfer pump 9 parts such as grade and position relationship are not limited to shown in the described and accompanying drawing of embodiment, and variety of components number and the locations of structures relation that can solve technical problem of the present utility model all belong within the scope of the utility model protection.
