Description

Vehicle exhaust smokeless exhaust pipe

The utility model relates to the vehicle exhaust device for eliminating smoke and dust, and concrete is a kind of vehicle exhaust smokeless exhaust pipe.

Face today of 21st century at us, environmental pollution has become the problem that people are concerned about most, atmospheric pollution is an importance of environmental pollution, atmospheric pollution is mainly caused by the harmful gas of motor vehicle exhaust emission and the flue dust of factory chimney discharging etc., country has worked out vehicle exhaust, emission standards such as chimney smoke, in order to make motor vehicle exhaust emission up to standard, except measures such as regulation use unleaded gas, also can on the emission from vehicles pipe, install smoke elimination additional, the device of dedusting, the complex structure that existing this class device has, cost is higher, the smoke elimination that has, dust removing effects is relatively poor.

The purpose of this utility model provides a kind of vehicle exhaust smokeless exhaust pipe, and the cigarette that goes out, Disinfection Effect are good, simple in structure, and filtrate can be cleaned, and is easy to use, and cost is lower.

The purpose of this utility model is achieved in that

A kind of vehicle exhaust smokeless exhaust pipe mainly is made up of body and filtrate, it is characterized in that:

Body comprises outer tube and interior pipe, and outer tube is a hollow circular-tube, and an end is uncovered, and end has end wall in addition, and there is circular hole at this end wall center; Its open-mouth end cylindrical is with the end cap that is threaded, and there is circular hole at this end cap outer wall center; Interior pipe is formed the disjunctor pipe that inside and outside circle respectively has at least three sections protruding, scrobicular ring necks by be threaded beyond each transition joint pipe and two ends tube head of at least three sections pipes, and described two ends tube head respectively has the overhanging pipe end of thin neck;

In the body of interior pipe, be filled with the filtrate of aluminium wire, aluminium powder material;

Pipe is contained in the outer tube in described, and by the end cap location, overhanging pipe end of thin neck of pipe two ends tube head stretches out in the end wall circular hole of the two ends of outer tube and end cap respectively in this.

The utility model has following actively effective effect:

1. this product can be easily installed in Vehicular exhaust outlet pipe end, tail gas filters through aluminium wire, aluminium powder, and its black smoke and toxic substance are filtered thing absorption, and being disposed to airborne gas after the cigarette that goes out, sterilization can be up to standard, little to atmospheric pollution, do not influence the healthy of people.

The inwall of the interior pipe of this product be that multistage is protruding, scrobicular ring neck structure, make tail gas be on-rectilinear movement, help the filtration absorption of cigarette in the tail gas, poison, good filtration effect along inner pipe wall, and the convex-concave ring neck of outer wall is configured with the cooling that is beneficial to outlet pipe, increases the service life.

3. the filtrate of this product can conveniently take out flushing, reuse, and improves effect, reduces cost.

4. this product can be contained on the outlet pipe or silencing apparatus of various automobiles, tractor, motorcycle.
