Description

Vehicle exhaust composite purification device

Art

The utility model belongs to vehicle exhaust composite purification technology field.

Background technique

Vehicle exhaust contains CO, NO _x, CH and small carbon granules, they are the incomplete products of engine combustion.CO, NO in these effulents _xthere is severe toxicity to human body, and be the core forming haze after being discharged into air.Carbon hydride and small carbon granules are once enter the haze PM2.5 that air also directly becomes air.Therefore when a regional motor roll up density very high time, its effulent usually long-term suspension in atmosphere and a large amount of gathering form haze, becomes the main source of pollutant atmosphere PM2.5.According to the investigation of environmental administration of Beijing, Pekinese's haze has 35% to derive from vehicle exhaust.

There is a kind of precious metals pt, Au, Rh make three-way catalyst carries out purified treatment SCR technology to vehicle exhaust, namely select purification technics.Though but improve through for many years and still there is the easy poisoning and deactivation of catalyzer, expensive and strict to the proportion requirement of engine mixed gas, and exist can not process carbon monoxide and carbon hydride, small carbon granules shortcoming and be difficult to promote.

So China there is no a kind of desirable technical products processed vehicle exhaust so far, there is no the pollution that method fundamentally prevents and treats tail gas, particularly eliminate the pollution of PM2.5.

Summary of the invention

The utility model provides a kind of vehicle exhaust composite purification device, it is not affecting under engine operating condition prerequisite, accomplish easy for installation, user cost is cheap and effectively can remove CO, NO contained in vehicle exhaust _xgas and the poisonous and harmful substance such as trickle carbon granules, carbon hydride of failing to burn, reach effectively control PM2.5 and pollute object.

The utility model solves the technological scheme that its technical problem adopts: the utility model is made up of engine exhaust pipe, silencing apparatus, purifier parts, and purifier is arranged on automobile chassis; Silencing apparatus and blower fan UNICOM is made, the other end of blower fan and UNICOM of purifying chamber by air entraining pipe; Blower fan is arranged at the outside of purifier, and purifier inside is provided with purifying chamber and electric panel room, and both open with baffle for separating; Ammonia spirit, reactor, filter is provided with in purifying chamber; Circuit board, air pump is provided with in electric panel room; Automobile exhaust pipe is provided with injecting hole, spark plug; Injecting hole and air pump UNICOM is made by pipeline; Spark plug, circuit board high voltage wire connect; Wherein reactor is made up of porosity, air pipe; Filter is made up of active carbon, mesh, drawer plate; Reactor is immersed among ammonia spirit.

The beneficial effects of the utility model are: can remove the poisonous and harmful substance CO in tail gas completely, NO _xthe hydrocarbon etc. that gas and failing burns, and does not affect engine operating condition.The practical safety of its high-efficiency and economic is the desirable New Product of control PM2.5 public hazards.

Embodiment

As shown in Figure 2, reactor (9) is by porosity (14), and air pipe (27) is formed.The waste gas that air pipe (27) will be introduced from blower fan (6) sends into reactor (9), spray in ammonia spirit (8) through porosity (14) again, and realize in this course contacting with abundant stirring of ammonia spirit.

As shown in Figure 3, filter (10) is by active carbon (24), and mesh (25), drawer plate (26) is formed.Wherein active carbon (24) is placed among mesh (25), and the size of mesh is determined by activated carbon granule size.The effect of drawer plate (26) makes filter (10) become movable parts can pull and push replacing.

As shown in Figure 4, when power turn-on K switch ₁, MD ₁blower fan (6), MD ₂air pump (16) and module I C ₁start working.W0019 can change VDC into high-frequency alternating voltage, through transformer T ₁more than ten thousand volts high pressure are produced, from secondary winding L after boosting ₂be delivered to spark plug (22) through high voltage wire (23), in outlet pipe (1), produce electrical spark.

As shown in Figure 1, when power turn-on K switch ₁after due to the operation of air pump (16), it makes the air in air suck electric control chamber (12) after compression from suction port (28), by pump gas port (17), pipeline (20), injecting hole (3) injects in automobile exhaust pipe (1).

In general the exhaust gas temperature in automobile engine exhaust pipe can up to 700 degree, and the oxygen mix of the carbon monoxide under this high temperature condition in waste gas and injection fresh air chemical reaction will occur under spark plug (22) effect of lighting:

2CO+O ₂＝2CO ₂ (1)

So the carbon monoxide in waste gas is oxidized into innocuous gas carbon dioxide.NO and O meanwhile in waste gas ₂contact with the mixing in silencing apparatus (2) at outlet pipe (1), NO and O ₂fast symphysis can become NO ₂:

2NO+O2＝2NO2 (2)

Under the effect of blower fan (6), waste gas sprays from its porosity (14) from silencing apparatus (2) sucting reaction device (9) again.Because in purifying chamber (7), reactor (9) is immersed among ammonia spirit (8), so the NO in waste gas ₂and the new NO produced ₂have with ammonia spirit and fully contacted.Due to NO ₂and NH ₃chemical reaction can be there is and generate N ₂and H ₂o, its reaction equation is:

6NO ₂+8NH ₃＝7N ₂+12H ₂O (3)

So the harmful components in waste gas are all transformed into harmless CO ₂, N ₂and H ₂o.Under the positive air pressure of blower fan (6) drives, waste gas continues to flow into the PM2.5 particle of filter (10) under the suction-operated of active carbon layer in waste gas and other particles are blocked filtering, then enters air through relief opening (11).

Another effect of active carbon layer in filter (10) is, prevents shaking the ammonia spirit splashed and is discharged purifying chamber (7) with waste gas streams, realizes the iterative cycles of ammonia spirit in purifying chamber (7) and uses.The driving effect of the positive air pressure produced due to blower fan (6) counteracts reactor (9), and filter (10) loses for the additional flow resistance of air-flow, so the utility model can not affect the operating mode of motor.Can drawer plate (26) be extracted out replacing when active carbon layer absorption is saturated, then reuse.

As the effective component NH of the ammonia spirit (8) in purifying chamber (7) ₃be exhausted, by discharging valve (15), raffinate released.Then through filling opening (18), new ammonia spirit is poured into purifying chamber (7), the utility model can work on.Ammonia spirit in the utility model and active carbon be all inexpensive, easily purchase the article with nonhazardous, therefore above-mentioned use of the present utility model can not be affected.
