Description
Technical field
The present invention relates to IC Engine Designs and manufacturing technology field, are a kind of exhaustion pipe for reducing pollution.
Background technology
By the prior art, high-temp waste gas that internal combustion engine generates is discharged by common exhaust duct, it will usually generate some it is harmful after
Fruit or harm, e.g., 1）NOx compounds, fine particle lead to atmosphere pollution；2）High-temp waste gas leads to exhaust pipe, and easily heat is tired in itself
Labor is broken.A kind of New gas exhaust pipe is invented, reduces atmosphere pollution, it is required when being.
Invention content
The technical problem to be solved by the present invention is to：How engine exhaust gas is reduced to atmosphere pollution；How exhaust pipe is reduced
Ontology heat fatigue.
The technical solution adopted in the present invention is：By installing a spraying device in exhaust pipe, mist NOx adsorption is utilized
Compound, fine particle to reduce to atmosphere pollution, reduce exhaust pipe heat fatigue, realize goal of the invention.
The present invention includes following technical characteristic to realize technical purpose：A kind of exhaustion pipe for reducing pollution, has：Ontology, spraying system
System, makes mist agent；The ontology, has：Entrance, cavity, outlet；Entrance in succession, be fixed on the exhaust outlet of internal combustion engine；The spraying
System has：Sprayer, material storing box.
The sprayer in the cavity of ontology, can spray into cavity and make mist agent, make mist agent and formed in the cavity
Mist.
Further, the sprayer is mounted on ontology close to one end of entrance.
Further, the sprayer shows periodically injection in time；The sprayer injection frequency is discharged with internal combustion engine
The frequency of exhaust gas is identical.
Further, in one cycle, the sprayer is discharged with internal combustion engine at the beginning of spraying mist to cavity and is given up
It is synchronous at the beginning of gas.
Further, in one cycle, the sprayer sprays the time length ratio internal combustion engine exhaust waste gas of mist to cavity
Duration is slightly long.
It is further, described that make mist agent can be pure water；Can also be based on water, addition can dissolve NOx compounds
Substance.
Further, the entry position of ontology is higher than the outlet port of ontology.
Further, the sprayer can be directed toward the outlet of ontology.
Further, the sprayer can also be directed toward the entrance of ontology.
The beneficial effects of the invention are as follows：1）It is spouting from sprayer to make mist agent, in the cavity as mist, absorbing high temp gives up
NOx compounds in gas, fine particle, to reduce the degree of pollution air；2）Mist agent is made in injection in the cavity, absorbs energy,
Exhaust gas temperature is reduced, mitigates exhaust pipe heat fatigue itself, extends the service life of exhaust pipe.
Description of the drawings
A kind of exhaustion pipe for reducing pollution schematic diagrames of Fig. 1.
In figure, 1 ontology, 1.1 entrances, 1.2 cavitys, 1.3 outlets, 2 spraying systems, 2.1 sprayers, 2.2 storings
Case, 3 make mist agent.
Specific embodiment
Embodiment 1.
1 the present invention will be further described below in conjunction with the accompanying drawings.
A kind of exhaustion pipe for reducing pollution, has：Ontology 1, spraying system 2 make mist agent 3；The ontology 1, has：Entrance 1.1, chamber
Body 1.2, outlet 1.3；Entrance 1.1 in succession, be fixed on the exhaust outlet of internal combustion engine；The spraying system 2, has：Sprayer 2.1,
Material storing box 2.2.
The sprayer 2.1 in the cavity 1.2 of ontology 1, can spray into cavity 1.2 and make mist agent 3, make mist agent 3
Mist is formed in cavity 1.2.NOx compounds, fine particle in mist absorbing high temp exhaust gas.Then, mist together with exhaust gas from going out
Mouth 1.3 is discharged, and into ambient enviroment such as air, mist cools down in ambient enviroment such as air is converted into liquid, is detached from air,
NOx compounds that mist is adsorbed, fine particle are also detached from air therewith.Here, the fine particle includes but not limited to
PM2.5。
The spraying system 2, can be such, apply certain pressure, and mist agent 3 is made from material storing box by a certain number of
2.2 are transported to sprayer 2.1, and spray；This technology has been widely used in internal combustion engine fuel injection system, is the prior art,
Only, what internal combustion engine fuel injection system sprayed is fuel oil, and what inventive combustion engine fuel injection system sprayed is mist.
Further, the sprayer 2.1 is mounted on ontology 1 close to one end of entrance 1.1；With timely, sufficient absorption
Pollutant in exhaust gas.
Further, the sprayer 2.1 shows periodically injection in time；Because engine exhaust gas discharge has the period
Property, so, making mist agent 3 can also periodically spray.
2.1 injection frequency of sprayer is identical with the frequency of internal combustion engine exhaust waste gas；When internal combustion engine one discharges exhaust gas, spray
2 ability of mist system sprays mist to cavity 1.2, does not spray mist in institute's having time, and 3 usage amount of mist agent is made to save.
Further, in one cycle, the sprayer 2.1 to cavity 1.2 spray mist at the beginning of with internal combustion engine
It is synchronous at the beginning of discharging exhaust gas；As soon as when internal combustion engine discharge exhaust gas, spraying system 2 to cavity 1.2 ejection mist and
When, fully absorption exhaust gas in pollutant, enhancing effect.
Further, in one cycle, the sprayer 2.1 sprays the time length ratio internal combustion engine discharge of mist to cavity 1.2
The duration of exhaust gas is slightly long；I.e. sprayer 2.1 to cavity 1.2 spray mist end time relatively a little later, more fully to adsorb
Pollutant in exhaust gas.
Further, described to make mist agent 3 can be pure water, and the cost of pure water is low, and without secondary pollution；Can also be with
Based on water, addition can dissolve the substances of NOx compounds, such as alcohol, to increase NOx compounds in absorbing high temp exhaust gas, thin
The effect of particulate matter.
Further, 1.1 position of entrance of ontology 1 is higher than 1.3 position of outlet of ontology 1；To be conducive to make the discharge row of mist agent 3
Tracheae avoids being condensed into the possibility that water is stayed in 1.2 body of cavity.
Further, the sprayer 2.1 can be directed toward the outlet 1.3 of ontology 1, as shown in Figure 1；What is sprayed makes mist agent 3
Exhaust gas with entering from 1 entrance 1.1 of ontology meets in the same direction, has longer incorporation time, to be sufficiently mixed.
Further, the sprayer 2.1 can also be directed toward the entrance 1.1 of ontology 1（Do not illustrate）；What is sprayed makes mist agent 3
Exhaust gas with entering from 1 entrance 1.1 of ontology reversely meets, quickly to mix.
In the present embodiment, the internal combustion engine can be diesel engine or gasoline engine.The internal combustion engine can be four
It is stroke or two stroke.
The above is only presently preferred embodiments of the present invention, but it is understood that, the invention is not limited in disclosed
Embodiment and component, on the contrary, it is intended to cover be included within the spirit and scope of appended claims various changes
Type, feature combination, equivalent device and equivalent component.In addition, there is the size of the feature of each component in the accompanying drawings simultaneously
It is not limiting, wherein the size of each component can be different from describing the size of component in the accompanying drawings.Therefore, the present invention uses
In remodeling of the covering to the present invention and deformation, as long as they are in appended claims and the range of their equivalent scheme
Within.
