Abstract
The engine exhaust purifying method is characterized by injecting oxidant into exhaust passage between the air exhaust opening of fuel engine cylinder and waste-gas purifier purifying medium. This method can make the purifying medium of the purifier have sufficient oxygen supply in the course of purification reaction to greatly raise the purifying effect of the purifier, and also can notably lower the initial temp. of the medium reaction.
Description
The present invention relates to the exhaust pollution of the fuel engine of various vehicles, boats and ships is carried out the technology of purified treatment.
Fuel engine institute exhaust gas discharged is the primary pollution source of atmosphere.Carbon monoxide in the atmosphere (CO), hydrocarbon (HC), oxynitrides (NO
x) being mainly derived from the toxic emission in the fuel engine work, these three kinds of toxic substances are very harmful to human body.Environmental pollution problem such as photochemical smog, acid rain, black rain also mainly are that the exhaust pollution of fuel engine causes.
Fuel engine is widely used on various vehicles and the boats and ships, and the past, their waste gas of being discharged directly was discharged in the atmosphere without any purification, caused the severe contamination of atmosphere.People designed the exhaust pollution purifier afterwards, after the waste gas of fuel engine being discharged by purifying medium purifies, were drained in the atmosphere again, and it is controlled that expectation is polluted this class.But, after reality is used, prove that this its catharsis of simple purification style is extremely limited.In recent years, people take the method that the discharge portion at fuel engine installs catalyzer additional to improve purification ratio, and still, effect is still undesirable.
Studies show that through the inventor purifying effect of purifier is undesirable, be actually because purify in the reaction due to the reactant hypoxia.
The objective of the invention is: provide a kind of method that improves fuel engine exhaust pollution purifying effect, to alleviate the severe contamination that waste gas that fuel engine discharges causes atmosphere greatly.
Technological scheme of the present invention is: the cylinder exhaust port at fuel engine injects oxygenant to the exhaust passage between the purifying medium of catalytic converter.
Adopt technique scheme, make medium when purifying reaction, sufficient oxygen supply is arranged, thereby improved the purifying effect of purifier greatly, also obviously reduced the initial temperature of medium reactions.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the schematic representation of the inventive method.The implication of each label is among the figure: 1 is fuel engine; 2 is cylinder; 3 is cylinder piston; 4 is cylinder exhaust port; 5 is purifying medium; 6 is purifier; 7 is the purifier relief opening; 8 is aeration device; Aa represents the cylinder exhaust port interface; Bb represents purifier first order purifying medium front-end face; Cc represents purifier afterbody purifying medium front-end face; D, e, f, g represent the different parts of the cylinder exhaust port of fuel engine to the exhaust passage between the purifying medium of catalytic converter respectively, and wherein d is near cylinder exhaust port, and g is near the purifier medium, and e and f are between d, g.
According to the present invention, the position of injecting oxidant should be positioned at below the aa face, and the cc face is with a left side, Generally should be positioned at the bb face with a left side, such as positions such as d, e, f, g.
Oxidant of the present invention can be oxygen, oxygen containing air, ozone and Gao Meng The oxidants such as acid potassium.
Injection etc. be injected and be sprayed to the injection mode of oxidant of the present invention can for blower fan Mode.
Below for implementing four exemplary embodiments of the present invention.
Embodiment 1:
Select air oxidant for use, adopt the blower fan injection mode, the injection phase is selected in middle part, exhaust passage f point.
Embodiment 2:
Select air oxidant for use, adopt the blower fan injection mode, simultaneously from injecting near the d point of cylinder exhaust port with near two positions of g point of purifier medium.
Embodiment 3:
Select for use potassium permanganate to make oxygenant, adopt and spray injection mode, the injection phase is selected in middle part, exhaust passage f point.
Embodiment 4:
Select air oxidant for use, adopt the blower fan injection mode, the injection phase is selected in the cc face with the h point of the every body of the left first order with the right side.
Blower fan injection mode of the present invention can adopt electric fan, also can utilize the power of motor itself to drive blower fan work by certain type of belt drive.
According to the present invention, the oxygenation mode also can be placed oxygenant at cylinder exhaust port between the purifier medium except injection mode, by the oxygen content in the chemical reaction increase waste gas.
Claims (4)
1. method that improves fuel engine exhaust pollution purifying effect, it is characterized in that: the cylinder exhaust port at fuel engine injects oxygenant to the exhaust passage between the purifying medium of catalytic converter.
2. the method for claim 1, it is characterized in that: described oxygenant can be oxygenants such as oxygen, oxygen containing air, ozone or potassium permanganate.
3. the method for claim 1 is characterized in that: the injection mode of described oxygenant can be that blower fan injects and spray modes such as injection.
4. method as claimed in claim 3 is characterized in that: described blower fan injection mode can adopt electric fan, also can utilize the power of motor itself to drive blower fan work by certain type of belt drive.
