Specific embodiment:

Embodiment is shown in attached drawing 1~3, a kind of preventing return water and the automobile exhaust pipe with filtering decrease of noise functions, including exhaust Pipe 1, the exhaust pipe are three-way pipe structure, are equipped with an input end 101 and two outlet ends 102,103 in three-way pipe structure, The inner sidewall of the input end of exhaust pipe is welded with annular flange 2, and filtration, purification dress is removably installed in annular flange 3 are set, the filtering and purifying includes interconnecting piece 301 and purification hollow tube 302, and the purification hollow tube can be from annular It is passed through inside flange, interconnecting piece supports in annular flange, and interconnecting piece and annular flange are fixed by screw.Annular flange week Eight groups of threaded holes are laid with upwards, interconnecting piece is cirque structure, and eight groups of mounting holes, each group of peace are laid on interconnecting piece The corresponding one group of threaded hole in hole is filled, interconnecting piece is fixed in annular flange by eight groups of screws.

Active carbon layer 4, ceramic filter membrane 5, oxidation reaction layer 6 are from left to right successively installed in the purification hollow tube With alkaline material filled layer 7.The filtering and purifying of the application can be dismantled, when filtering and purifying after a period of use, It needs replacing internal active carbon layer, ceramic filter membrane, oxidation reaction layer and alkaline material filled layer, as long as by vent gas treatment After pipe is disassembled from connector, screw is unloaded, so that it may disassemble filtering and purifying, easy to disassemble, replacement It is convenient.

One of outlet end opening upwards of exhaust pipe, Open Side Down for another outlet end of exhaust pipe；Be open to Under outlet end inner sidewall be equipped with sliding rail 8, the inside for the outlet end that Open Side Down and be located at sliding rail end be welded and fixed It is installed with baffle 9, the middle part of baffle is equipped with venthole 901, is slidably matched on the sliding rail and is installed with waterproof baffle 10；It is described anti- The central area of water baffle is enclosed construction, and the peripheral circumferential direction that central area is located on waterproof baffle is equipped with one and irises out stomata 11, the lower part of the waterproof baffle and be located at every group of venthole opposite position at be installed with one group of exhaust pipe 12 respectively, it is described Venthole is distributed in waterproof baffle circumferential direction, and venthole is 8 groups in the present embodiment.

The diameter of the central area of the waterproof baffle is greater than the aperture for the venthole being equipped in the middle part of baffle, encounters rain in this way When water flows backward, waterproof baffle can move up along sliding rail and pass through baffle, and after blocking, exhaust pipe can be enclosed, tail Gas cannot be discharged from the outlet end that Open Side Down；Being welded and fixed to be installed in the middle part of the sliding rail can stop waterproof baffle to move down Block 13.

The lug boss 14 that can change airflow direction is welded on the inside tube body of the three-way pipe structure, it is described convex The portion of rising is semicircle or half elliptic, and lug boss can change airflow direction, weakens the noise that air-flow generates.

When no water flows backward, waterproof baffle is stopped by block, the very big gap of mutual between waterproof baffle and baffle, Tail gas is exhausted, to realize tail gas after filtering and purifying filtration, purification by two outlet ends of exhaust pipe First time noise reduction；When wherein by outlet end, lug boss changes airflow direction, reduces the noise of air-flow, realizes tail gas Second of noise reduction；When tail gas is by the outlet end that Open Side Down, venthole 901 of the tail gas first in the middle part of baffle is passed through, so It is discharged afterwards from the exhaust pipe 12 set up in the lower part week of waterproof baffle, the third time noise reduction of tail gas, final gas has been achieved Body leaves exhaust pipe with minimum sound.

The sliding rail is four sliding slots being symmetrically distributed on the inner sidewall for the outlet end that Open Side Down.The waterproof baffle 10 be circular ring structure, and four groups of sliding blocks 1001 to match with the sliding slot are symmetrically arranged in the circumferential direction of circular ring structure, sliding block cooperation It is installed in sliding slot, and can be moved along sliding slot.

The internal diameter of the exhaust pipe and the internal diameter of venthole are identical.

The length of the exhaust pipe is identical as the length of lower end surface of the upper surface of block to the outlet end that Open Side Down.

When utility model works, in exhaust gas discharge, exhaust gas enters filtering and purifying, and active carbon layer absorbs car tail Larger solid particle and some gases in gas, flow through ceramic filter membrane by the vehicle exhaust of active carbon layer, in ceramic filter Under the filtration of film, most solid particles are left in vehicle exhaust, and the vehicle exhaust for flowing through ceramic filter membrane flows through Oxidation reaction layer, reducibility gas and oxidant reaction in vehicle exhaust, the reducibility gas in vehicle exhaust are oxidized, pass through The vehicle exhaust of peroxidization layer flows through alkaline material filled layer, and the oxidizing gas in vehicle exhaust and alkalization reducing agent are anti- It answers, oxidizing gas is reduced, and sour gas is absorbed, and enters outlet end by alkaline material filled layer, in three-way pipe structure Inside tube body be equipped with and can change the lug boss of airflow direction, lug boss can change airflow direction, weaken air-flow and generate Noise；Tail gas a part is discharged from the outlet end of opening upwards, and another part of tail gas is arranged by the outlet end that Open Side Down When out, by the outlet end that Open Side Down, venthole 901 of the tail gas first in the middle part of baffle is passed through, then under waterproof baffle Exhaust pipe 12 that portion is set up in week is discharged, and has been achieved the third time noise reduction of tail gas, final gas with minimum sound from Begin to rehearse tracheae.

In the section for encountering rainy weather or approach ponding, when position is lower, water will push waterproof baffle along on sliding rail It moving, waterproof baffle is made to contact baffle, waterproof baffle is supported in baffle bottom, and exhaust pipe is sealed by baffle at this time, and stop water to flow backward, Vehicle exhaust is discharged from the outlet end of opening upwards, it can be ensured that automobile reaches home, can effectively prevent water from exhaust pipe Tail portion, which is flowed backward, enters exhaust pipe and engine, effectively prevent exhaust pipe and engine damage.The utility model principle structure is simple, It is easy to use, effectively by Vehicular exhaust filtering and noise reduction, while environmental protection.

Above-described embodiment is the specific descriptions carried out to the utility model, is only carried out furtherly to the utility model It is bright, it should not be understood as the restriction to scope of protection of the utility model, those skilled in the art is according in above-mentioned utility model Appearance is made some nonessential modifications and adaptations and is each fallen within the protection scope of the utility model.
