Abstract

The utility model discloses an exhaust pipe tail gas filtering and silencing exhause which is used for filtering automobile exhaust and silencing. The exhaust pipe tail gas filtering and silencing exhause comprises a gas inlet pipe, a shell body and a gas outlet pipe. The exhaust pipe tail gas filtering and silencing exhause is structurally characterized in that a filtering screen is placed, the gas outlet pipe is located inside the shell body and is of an integral structure with the shell body, the gas inlet pipe, the filtering screen and the gas outlet pipe are sequentially connected and fixed in a sleeved mode, and the gas inlet pipe and the gas outlet pipe are provided with a plurality of through holes. The exhaust pipe tail gas filtering and silencing exhause can effectively filter solid particulate matter and other hazardous substances in the automobile exhaust, and has a silencing function.

Description

A kind of tail gas from exhaust pipe filters noise reduction tail larynx

Technical field

The utility model relates to a kind of automobile exhaust pipe tail larynx, and especially a kind of tail gas from exhaust pipe filters noise reduction tail larynx, is used for automobile and carries out tail gas filtering and noise reduction.

Background technique

Along with the increase of automobile quantity, its tail gas that gives off is also increasing to the negative effect of environment, and is especially serious day by day to The Surroundings in Cities harm.Major pollutants are hydrocarbon, oxynitrides, carbon monoxide, sulfur dioxide, lead-containing compounds, Benzpyrene and solid particulate matter in the vehicle exhaust, these harmful matters not only cause PM2.5 to increase, produce haze weather, cause human respiratory system's disease, also increase the weight of urban heat land effect, existent environment of people sharply worsens.In addition, old vehicle of time is except tail gas pollution, and noise pollution is also very serious, and some vehicle sounds of reequiping outlet pipe is also very big.And at present on the market all automobile tail larynx all only possess decorating action, do not filter and erasure effect.

China's model utility 201220179258.9 discloses a kind of tail gas from exhaust pipe filtrating equipment, and it comprises crossing filter ruffle, being filled in the catalyzer in the filter ruffle of suction port, housing, relief opening, housing inner clip plate, pressing plate below.This device exist gas output little, influence exhaust, susceptible to plugging shortcoming, and do not possess silencing function.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of solid particulate matter and other harmful matters in the vehicle exhaust of both can effectively having filtered, and the tail gas from exhaust pipe that possesses silencing function again filters noise reduction tail larynx.

The utility model addresses the above problem the technological scheme of taking: this tail gas from exhaust pipe filters noise reduction tail larynx and comprises suction tude, housing and steam outlet pipe, its structural feature is also to be provided with filter screen, wherein steam outlet pipe is positioned at housing and is structure as a whole with housing, suction tude, filter screen, steam outlet pipe socket are successively fixed, and all have some vents on suction tude and the steam outlet pipe.

One end of housing described in the utility model and steam outlet pipe is provided with the housing screw socket, and an end of suction tude is provided with the suction tude screw socket, and housing screw socket by matching each other of suction tude, filter screen, steam outlet pipe, suction tude screw socket socket and screw thread are successively fixed.

Filter screen described in the utility model is cylindric.

The utility model compared with prior art, has following beneficial effect: between suction tude and steam outlet pipe, be provided with filter screen, have some vents in suction tude and steam outlet pipe, both played the effect of filtering solid particulate matter and other harmful matters in the vehicle exhaust, possessed erasure effect again; Quick and easy for installation, only need slice off the original tail larynx on the automobile exhaust pipe, then suction tude welding or cover are received on the automobile exhaust pipe; Also have install that cost is low additional, the advantage of instant effect, applied widely, easy to maintenance, long service life.

Embodiment

Referring to Fig. 1-Fig. 3, present embodiment comprises suction tude 2, housing 1, steam outlet pipe 3 and filter screen 4, all has some vents 5 on suction tude 2 and the steam outlet pipe 3, and filter screen 4 is cylindric.Wherein steam outlet pipe 3 is positioned at housing 1 and is structure as a whole with housing 1, one end of housing 1 and steam outlet pipe 3 is provided with housing screw socket 6, one end of suction tude 2 is provided with suction tude screw socket 7, and housing screw socket 6 by matching each other of suction tude 2, filter screen 4, steam outlet pipe 3, suction tude screw socket 7 socket and screw thread successively are fixed together.

When installing and using, cut away the original tail larynx on the automobile exhaust pipe earlier, then suction tude 2 is connected on the automobile exhaust pipe, Connecting format can adopt welding or socket, housing 1 and suction tude 2 is screwed by screw socket to get final product then.When dismounting is safeguarded, housing 1 rotation is unscrewed, take off housing 1, take out filter screen 4 again and clean, replaceable filter screen 4 in case of necessity reinstalls successively at last and gets final product.

The utility model adopts stainless steel to make, and contains manganese oxide as catalyzer on the filter screen 4, but is not limited thereto a kind of material, also can have the material of strainability for other.
