Embodiment 1

[0051] Such as Figure 1~6 As shown, the automobile exhaust purification system of the present embodiment is contained in the air inlet end of muffler pipe 100, and it comprises casing 10a, carbon paper 41, carbon paper roll 42,43, sensor 70, rolling bar 15, miniature Slow speed motor 30, control circuit, the parts such as the paper tube 20 in the muffler pipe as the indicator light of signal prompting device. The activated carbon paper of the invention adopts the non-woven fabric with high temperature resistance, tensile strength, good permeability and easy degradation as the base material. Among them, the control circuit is set in the appropriate position of the car, for example, it can be set inside the driver's console, or installed with the control circuit of the car, or integrated in the central control system of the car, and the indicator light is set in the cab, such as Figure 7 As shown, the control circuit is electrically connected with the micro slow motor, the se...

Embodiment 2

[0063] Such as Figure 8 As shown, the purification method of this embodiment is the same as that of Embodiment 1, and the system structure is basically the same. The only difference is that the miniature slow-speed motor is arranged on the inner wall of the box body 10a, and the output shaft of the motor is connected with the active carbon paper roll mounting seat. .

Embodiment 3

[0065] Such as Figure 9-10 Shown is embodiment 3 of the present invention, the principle of the purification method of this embodiment and embodiment 2 is the same, the system structure is then basically the same, but the box body adopts two split type box bodies 10b. These two split boxes are parallel to each other and are located above the muffler pipe. They are arranged at a certain distance according to the space under the tail box of the car body. cover. The active mounting base 13 and the passive mounting base 12 are separately installed in two split boxes.

[0066] The opposite inner sides of the bottoms of the two split-type boxes are respectively provided with smooth transitions and horizontally extending belt-shaped tubes 11, the outer ends of the belt-shaped tubes 11 are open, and each belt-shaped tube is respectively sleeved with a heat-insulating fiber or An elastic pipe joint 60 made of metal; a T-shaped tee pipe 16 with two ports 161, 162 on its upper part, e...

Abstract

The invention relates to an automobile exhaust purification method and an automobile exhaust purification system thereof. The automobile exhaust purification method comprises the following steps of winding one end of activated carbon paper (41) on active and passive carbon paper rolls (42) in tank bodies (10a, 10b), winding the other end thereof on the active carbon paper roll (43), and winding the part between the two ends on a paper tallying tube (20) on an exhaust channel in an automotive muffler tube (100); when the activated carbon paper adsorbs and is saturated with harmful substances, rotating the active carbon paper roll (43), correspondingly rolling the old activated carbon paper on the paper tallying tube (20) onto the active carbon paper roll, simultaneously driving the passive carbon paper roll (42) to rotate by the carbon paper, releasing and rewinding new activated carbon paper on the paper tallying tube, and stopping rotating when winding one circle of new carbon paper on the paper tallying tube; and when completely releasing the new carbon paper on the passive carbon paper roll, replacing the passive carbon paper rolls and the active carbon paper rolls. The invention utilizes the replaceable activated carbon paper to adsorb the harmful substances in exhaust with lasting effect, does not obstruct exhaust emission and noise damping, and the use of the carbon paper does not cause secondary pollution to environment.

Description

technical field [0001] The invention relates to a method for purifying automobile tail gas outside the automobile engine and a purification system for realizing the method. Background technique [0002] At present, in terms of technology to reduce harmful exhaust emissions from automobiles, in addition to starting from the fuel itself, there are organic internal control methods and external control methods. The internal control method is to improve the design of the engine structure and its control system according to the generation mechanism of harmful emissions, and adopt new technologies and new processes such as electronic injection method to make the fuel mixture in the engine burn fully and efficiently so as to reduce harmful gases purpose of discharge. The external control method is the three-way catalytic converter commonly used at present, which is usually located between the exhaust manifold and the muffler, mainly through palladium (Pd) and platinum (Pt) attached...
