Description

Automobile exhaust purifier

Patent of the present invention; Automobile exhaust purifier is to belong to vehicle exhaust environmental protection field, and a kind of equipment of purifying vehicle exhaust is provided to vehicle exhaust.

Because at present tail gas discharges under the condition of high temperature, principle says and atomizes not that fuel oil does not have, and the dioxygen oxidation that goes out through catalysis again falls major part, so detect the outlet that flow to that fuel oil not has only minute quantity in the exhaust emissions outlet, several PPm that cooling is separated out not fuel oil that atomizes.Gasifying not, fuel oil detects to come out.So detected data are illusions, because; Gasify after fuel oil does not advance atmosphere; The atomizing that the P6-8 particle diameter is separated out in cooling is fuel droplet not; The water smoke that burning and catalysis-oxidation produce drips to drip with airborne P6-8 particle diameter water smoke and bumps the building, has polluted airborne purified water again, and water oil contact halogenation becomes approaching white halogenation liquid droplet to be suspended in airborne bottom; Just become one of main constouctional material of haze, so present exhaust gas purification equipment is not perfect.Ternary catalyzing unit is not final exhaust gas purification equipment.

Water when the 6-8 micron, calm just being suspended in the atmosphere, the 6-8 micron mist of oil lighter than water drips more easily and is suspended in the atmosphere.86 years aerosol chief scientists of Tsing-Hua University, the doctoral advisor, professor Yao Qiang says; He stands in Beijing Xiang Shanding and overlooks Beijing, and the Beijing city sky is covered with one deck grey gas lid, does not see Beijing city.There is not to isolate not fuel oil and 6-8 micron technology and the equipment that not fuel droplet and water smoke drip that atomizes that gasifies in the tail gas at present.

International Olympic Committee's meeting had one " rain " to occur " blue sky " explanation in second day suddenly eve in 2008; " rain " and can purge the pollutant of carrying secretly in the vehicle exhaust.That is to say; The equipment that " rains " can will be suspended in liquid mist in the tail gas (not fuel oil, water, by the droplet of liquid parcel soot dust granule) near 100% separate.The nucleus equipment of the automobile exhaust purifier of patent of the present invention that Here it is.

The cleaning equipment of automobile exhaust purifier patent and ternary catalyzing unit does not exist together;

Be originally that purifying vehicle exhaust is that tail gas behind the ternary catalyzing unit is through hush pipe outlet discharging.

The present invention is catalyst converter (a 1) back serial connection spraying tube (2), is connected in series wet electrostatic device (3) again,

Spraying tube (2) and wet electrostatic device (3) lead to circulating box (4),

Circulating box (4) outlet connects recycle pump (5), and recycle pump (5) outlet connects nozzle (6) effect in the spraying tube (2);

Behind the wet electrostatic separator, all contaminants of tail gas is separated near 100%, and discharge tail gas is near the saturated transparent tail gas of normal temperature.

The purpose of purifying vehicle exhaust technology;

Purifying vehicle exhaust is discharged to pollution-free state, and reclaim pollutant.

Tail gas clean-up implementation of processes scheme;

One, high temperature automotive tail gas leaves unit's three catalyst converters (1) catalysis that motor advances serial connection and goes out oxygen and nitrogen,

Two, tail gas advances the spraying tube (2) of ternary catalyzing unit (1) serial connection again after the catalysis, in pipe, with nozzle (6) atomization of liquid is sprayed the tail gas cooling, and tail gas becomes vaporific tail gas.

Three, vaporific tail gas advances the wet electrostatic device (3) of serial connection again and isolates; Solid particle, water, oily mixed solution near normal temperature advance circulating box (4)

Four, the circulating liquid in the circulating box (4) is through recycle pump (5) into nozzle (6) the atomizing spray tail gas that boosts.

Five, the isolated clean gas tail gas of wet electrostatic device (3) discharges through hush pipe (7).

Six, wet electrostatic device (4) is made up of static body a and power supply b.

Static body a is made up of hush pipe (7), ceramic insulator (8), electrical hachure (9)

Power supply b positive pole connects electrical hachure (9), negative pole connects hush pipe (7) wall

Effect; Free of contamination 2 carbonoxide gas and nitrogen under the discharging saturation state.

Solid particle, the gasification of elimination vehicle exhaust and atomize fuel oil, 1 carbonoxide gas, nitrogen oxide, polluted water pollution near 100%.
