Abstract
The utility model discloses an automobile exhaust processing unit which comprises a cylinder body. An air inlet is formed in one end of the cylinder body, an air outlet is formed in the other end of the cylinder body, the air inlet end of the cylinder body are provided with cellular carriers, first light sources are arranged among the cellular carriers, spiral carriers are arranged behind the cellular carriers, second light sources are arranged at the central shafts of the spiral carriers, and photocatalyst is arranged on the cellular carriers and the spiral carriers. A two-stage catalytic unit is adopted by the automobile exhaust processing unit to carry out reprocessing on tail gas processed by a three-way catalyst and strive to reach the low emission of tail gas polluted gas and to enable the hazard of the tail gas to the atmosphere to be reduced to the minimum degree. Due to the fact that a mature photocatalytic technology is adopted, the automobile exhaust processing unit is low in cost, durable and capable of being used in a cyclic mode many times compared with precious metal catalyst.
Description
Technical field
The utility model relates to a kind of automobile exhaust gas processing apparatus, is specifically related to a kind of ternary catalyzing unit automobile exhaust gas processing apparatus afterwards that is used in.
Background technique
Automobile exhaust pollution is the environmental pollution that the waste gas by motor vehicle emission causes.Major pollutants are hydrocarbon, oxynitrides, carbon monoxide, sulfur dioxide, lead-containing compounds, Benzpyrene and solid particulate matter etc., can cause the photochemical smog phenomenon.
The city major street is subjected to the investigation of automobile exhaust pollution and the pollution rule that comprehensive analysis obtains CO, NOx, HC, CO, NOx annual average have exceeded national atmosphere quality secondary standard in the air of center, major street road, and NOx content has exceeded secondary standard in the walk air of urban district major street.CO content exceeds standard in II, the III class road walk air; In three class streets, I class street vehicle flowrate maximum, the II class is taken second place, and the III class is minimum, and motor vehicle emission tail gas is that the III class is the heaviest, the II class is taken second place, the I class is the lightest to street atmospheric pollution situation.
Therefore, it is imperative to seek a kind of novel tail gas treatment process.
Administer vehicle exhaust both at home and abroad and mainly contain three approach:
The first, the power of change automobile is basic and the most final approach.As develop electric vehicle and substitute fuel automobile.This approach does not produce automobile or only produces seldom dusty gas.It is power that yet existing automobile mainly is still with gasoline, and this scheme short run effect is not obvious.
The second, improve existing automotive powerplant and fuel oil quality.Adopt excellent in design motor, improve chamber structure, adopt new material, improve fuel oil quality etc. automobile gas emission pollution is reduced, but can not reach " zero-emission ".
The 3rd, also be being applicable in a large number at the purification technics with car and new car of extensively adopting at present.Be to adopt some advanced external purification technology that the waste gas that automobile produces is purified to reduce pollution, this approach can not reach " zero pollutes ".The external purification technology is exactly that various purification plants are installed in the vent systems of automobile, adopts the pollutant in method minimizing exhaust physics, chemistry.Can be divided into two classes such as catalyst converter, thermal reactor and filtration trap.The former is many for gasoline automobiles, and the latter is used for diesel engine automobile more.
What wherein catalyst converter was relatively more commonly used is: catalyst, namely ternary catalyzing unit is mainly made catalyzer with platinum, palldium alloy.The working principle of ternary catalyzing unit is: when the vehicle exhaust of high temperature passes through purification plant, purifying agent in the ternary catalyzing unit will strengthen the activity of CO, HC and three kinds of gases of NOx, impel it to carry out certain OR chemical reaction, wherein CO at high temperature is oxidized into colourless, nontoxic carbon dioxide; The HC compound at high temperature is oxidized to water (H
20) and carbon dioxide; NOx is reduced into nitrogen and oxygen.Three kinds of harmful gases become innocuous gas, and vehicle exhaust is purified.
Key reaction equation: 2CO+2NO==2CO
2+ N
2Yet the tail gas of handling through ternary catalyzing unit still contains the harmful components of low density.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of automobile exhaust gas processing apparatus is provided, and it can be used on after the ternary catalyzing unit, further removes the harmful gas in the tail gas.
The technical solution of the utility model realizes in the following manner: a kind of automobile exhaust gas processing apparatus, comprise cylindrical shell, cylindrical shell one end is provided with suction port, the other end is provided with the air outlet, described cylindrical shell inlet end is provided with honeycomb support, be provided with first light source between the honeycomb support, the honeycomb support rear is provided with the spiral carrier, and the central axis of spiral carrier is provided with secondary light source, and honeycomb support and spiral carrier are provided with photocatalyzer.
Described first light source is the dual torus light source.
Described secondary light source is cylindrical light source.
The utility model adopts the two-stage catalysis device, the tail gas that ternary catalyzing unit was handled is handled again, make every effort to reach the low emission of tail gas pollution gas, make tail gas drop to minimum to the harm of atmosphere, and adopt ripe photocatalysis technology, with respect to precious metal catalyst, it is with low cost, durable in use, can repeatedly recycle.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of automobile exhaust gas processing apparatus, comprise cylindrical shell 1, cylindrical shell 1 one ends are provided with suction port 2, the other end is provided with air outlet 3, described cylindrical shell 1 inlet end is provided with honeycomb support 4, is provided with first light source 5 between the honeycomb support 4, and honeycomb support 4 rears are provided with spiral carrier 6, the central axis of spiral carrier 6 is provided with secondary light source 7, and honeycomb support 4 and spiral carrier 6 are provided with photocatalyzer.
Used photocatalyzer is nano-TiO in the utility model
2, TiO
2Under the light source irradiation, carry out the catalytic oxidation-reduction reaction.In addition, the utility model also can adopt the photocatalyzer of other types.The utility model working principle is as follows: the gas of handling through ternary catalyzing unit enters in the cylindrical shell through suction port 2, at first be to obtain one-level to handle, one-level is handled and is adopted wide-aperture honeycomb support 4 loaded optic catalysts, not only kept bigger specific surface area, and bigger exhaust port reduced droop loss, guarantees normal Throughput; The secondary treatment stage is considered the problem of aeration resistance, so abandoned the deflection plate method, and adopted the catalyst carrier form of spiral-type, such pressure drop meeting is very little, when discharging by air outlet hole 3 through the gas after the secondary treatment, harmful gas is processed substantially clean.
As preferred version of the present utility model, described first light source 5 is the dual torus light source.The light source of dicyclo type can guarantee that each aperture of honeycomb support 4 can both obtain good illumination, guarantees light-catalysed efficient catalytic reaction.
As step improvement more of the present utility model, described secondary light source 7 is cylindrical light source.Adopt elongated cylindrical light source, form concentric circles with spiral carrier 6, make the surface of spiral carrier receive the illumination of same degree simultaneously, thereby catalytic reaction is fully reacted the dusty gas of low density.
