Abstract
The utility model relates to a dual-loop automobile tail gas clean-up system, which is installed on an exhaust pipe between an automobile engine and a silencer and has a dual-chamber structure. The dual-loop automobile tail gas clean-up system comprises an air inlet, a joint opening, a filter screen, an oil gathering bottle, a catalytic reaction chamber and an air outlet. With the granule filtration by the filter screen and the chemical reaction within catalyzer effect, the utility model can effectively lower the pollution of automobile tail gas.
Description
Technical field
The utility model belongs to field of environment protection, especially a kind of double loop automobile tail gas purification system.
Background technique
Automobile is discharged a large amount of carbon monoxide, hydrocarbon, nitrogen oxide, fine particulates and sulphide etc.These primary pollutions also can generate secondary pollutions such as photochemical smog, acid deposition by atmosphere chemically react.The technology that reduces tail gas pollution at present mainly adopts the means of emission controls by improving combustion, by modulation to engine and carburetor, carrying out the system point ignition system improves, improve the firing chamber, exhaust gas recirculation, the means of improving fuel qualities reduce harmful matter and generate, and its difficulty is big, lead time is long, so emission controls by improving combustion can not fundamentally solve the tail gas pollution problem.
Summary of the invention
The utility model purpose provides a kind of double loop automobile tail gas purification system, and it can simple and effective reduction automobile exhaust pollution problem.
The purpose of this utility model is achieved through the following technical solutions:
The double loop automobile tail gas purification system is installed on the outlet pipe between motor car engine and the baffler, and is two chambers body structures, comprises intake grill, interface, filter screen, oil-collecting bottle, catalytic reaction chamber and exhaust outlet.Adopt the method for two chamber bodies and usefulness, alleviated the resistance that waste gas is got rid of, increased reactant and catalyzer area of contact, and when a side reaction chamber fault, can meet an urgent need.Intake grill is connected with the motor car engine exhaust outlet, the shunting back enters the filter screen that the catalytic reaction chamber front end connects from two chambers body one end interface, by filter screen abundant comburant and the foreign material that suspend in the tail gas are not filtered, its oil dripping by the filter screen lower end is fond of salty food drops in the oil-collecting bottle, prevent that solid particle from entering catalytic reaction chamber and causing catalyzer death.Enter catalytic reaction chamber through the tail gas that filters, under the effect of catalyzer, generate innoxious substance, collaborate again to enter mobile muffler by exhaust outlet.
The beneficial effects of the utility model are: simple in structure, economical and practical, be easy to promote, and can effectively reduce the pollution problem in the vehicle exhaust.

Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises intake grill 1, interface 2, filter screen 4, oil-collecting bottle 6, catalytic reaction chamber 7, interface 9, exhaust outlet 3, oil dripping mouth 5, catalyst carrier 8.
Tail gas is discharged from motor, enters the filter screen 4 that catalytic reaction chamber 7 front ends connect by intake grill 1 shunting by an end interface 2, and filter screen 4 is eight layers of close filter screen, and is made by Stainless Steel Wire, also can be that other materials is made.Reduced in a large number fully by eight layers of close filter screen that comburant and foreign material enter catalytic reaction chamber 7, both strengthened purifying effect, prolonged catalyzer working life again.Oil dripping mouth 5 by the filter screen lower end is deposited in the oil-collecting bottle 6 then, and oil-collecting bottle 6 is a conical flask, also can be shape such as circular, square, and is made by glass fibre reinforced plastics, also can be that other materials is made.Enter catalytic reaction chamber 7 through the tail gas that filters, anti-catalyst for application is the oxide of copper, iron, and catalyst carrier is a ceramic honey comb, this loose porous structure, make waste-gas cleaning more abundant, and ceramic chemical property is stable, thereby is difficult for influencing reaction effect with other substance reaction.Through collaborating again to enter mobile muffler after the catalytic reaction purification by exhaust outlet.Effectively reduced the pollution of vehicle exhaust.
