Abstract

The utility model relates to a device for reducing pollution of waste gas of an internal combustion engine. An ozonizer 6 is arranged in the utility model by an insulating support frame 5, and the front end of the ozonizer 6 is provided with a miniature blower fan 2. When the internal combustion engine works, the ozonizer 6 generates ozone which is rapidly combined with CO and HG exhausted by a muffler to generate innoxious matters to be exhausted. The discharge pollution of the internal combustion engine can be reduced above 70 percent. The ozonizer 6 can be an ozone pipe or an ozone generating slice.

Description

Internal-combustion Engine Exhaust Air Depollution Device

Technical field

The utility model belongs to the device that internal-combustion engine reduces exhaust pollution, specifically refers to be installed on the polluting device that falls on the internal-combustion engine vent-pipe.

Background technique

At present, the exhaust emission of Motor Vehicle has been the big public hazards of one in people's daily life, especially densely populated city, and this public hazards are more and more tortured people's human body.In order to reduce this pollution, the someone proposes some ways, as subtracts rare inflammable mixture; Add fixed filter at the silencing apparatus afterbody; Absorb CO and HC or the like with alkali metal platinum.These ways are not only produced effects not quite, and working life is short, have reduced the power of internal-combustion engine, even some costs an arm and a leg, and can't popularize, so all inadvisable.

Summary of the invention

The purpose of this utility model is, design a kind of Internal-combustion Engine Exhaust Air Depollution Device, the harmful gas that can effectively internal-combustion engine vent-pipe be discharged is that innoxious substance enters atmosphere at the quick be combined into of ozone of silencing apparatus afterbody and the generation of this device, plays and reduces the effect that engine exhaust gas pollutes.

Design proposal of the present utility model is to utilize the metal tube device of adorning ozonizer and small blast fan in one, this device is installed in the rear portion or the afterbody of silencing apparatus.When internal combustion engine, ozonizer produces ozone, and through the effect of small blast fan, the harmful gas that ozone and silencing apparatus are discharged engages, and becomes innocuous gas rapidly and discharges, and above-mentioned ozonizer can be ozonizer or ozone generation flake.As everyone knows, ozone is that extremely strong oxygenant can be rapidly and the CO that discharges of internal-combustion engine, and the HC reaction generates innocuous gas.Practical operation explanation when ozone incidence rate during in 50 milligrams of left and right sides of per minute, imports 750 milliliters petrol engine silencing apparatus afterbody with this device, and (CO) that is discharged (HC) relatively reduced by 80% when being unkitted this device.

The utility model engages accompanying drawing, and details are as follows.

Embodiment

As shown in Figure 1, the agent structure of the design's Internal-combustion Engine Exhaust Air Depollution Device is on the support 3 of the inlet end 1-1 in the metal tube 1 of both ends open a micro-blower 2 to be housed, utilize two support 5 ends that ozonizer 6 is arranged in outlet side 1-2 one side, this ozonizer can be traditional ozone generating pipe, also can be novel ozone generation flake.The electric power of this device is from the power supply 10 of Motor Vehicle, and above-mentioned power supply is connected with oscillator 7 through lead 9, is connected with ozonizer 6 through lead 8 again; This automobile power source 10 is connected with blower 2 through lead 8-1 again.When internal-combustion engine is started working, open ignition switch, start ozonizer 6 and blower 2 simultaneously, the ozone that the flabellum 4 that makes blower 6 is produced ozonizer 6 blows out 1 from outlet side 1-2 and combines with waste gas that internal-combustion engine is discharged, improves the quality of waste gas.Fig. 2 and Fig. 3 represent that the situation that polluting device is installed on outlet pipe falls in the design's I. C. engine exhaust body.Fig. 2 represents that a connection mouth 11 is arranged at the rear portion of silencing apparatus 12, and the outlet side 1-2 of metal tube 1 is welded on the connection mouth 11.Burning when internal combustion engine, directly combine generation with ozone falls dirty effect to the waste gas that is produced by exhaust inlet pipe 13 backs, discharges through waste gas steam outlet pipe 14 again.Fig. 3 is illustrated on the waste gas steam outlet pipe 14 and with clip 17 expansion chamber 15 is installed, and this expansion chamber can make the waste gas of discharge produce eddy flow.And the outlet side 1-2 of metal tube 1 is communicated with expansion chamber 15 through flexible pipe 16.At this moment, waste gas enters expansion chamber 15 behind silencing apparatus waste gas steam outlet pipe 14, and combines with ozone in expansion chamber 15, produces the dirty effect of falling, and discharges from expansion chamber 15 again.

The utility model is reasonable in design, and is simple in structure, easy for installation, makes especially simply, and with low cost, and it can be widely used on various gas and oils or the diesel engine.Can make with producing the different ozonizer of ozone concentration according to the difference of internal combustion engine volume.
