Description

An energy-saving and environment-friendly sound-absorbing exhaust pipe

technical field

The utility model belongs to the field of energy saving and emission reduction of automobiles, in particular to an energy-saving, environment-friendly and noise-absorbing exhaust pipe.

Background technique

With the development of economy and society, more and more cars have entered people's lives, and with the improvement of people's attention to the environment, people's environmental protection requirements for cars are also getting higher and higher. The trachea can only eliminate the noise of the automobile exhaust during the exhaust process and reduce noise pollution. When the exhaust gas emitted by the automobile has more harmful gases and particles, in order to achieve the effect of environmental protection, people install other Purification device, due to the limitation of installation location and installation space, the purification effect of the purification device is not very ideal.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides an energy-saving and environment-friendly muffler exhaust pipe, which can effectively catalyze, filter and silence the harmful gas discharged from the automobile, and realize two times of filtering, greatly reducing the effective gas emission, play the role of environmental protection and noise reduction.

The technical scheme that the utility model adopts is as follows:

An energy-saving and environment-friendly muffler exhaust pipe, comprising an exhaust pipe body, air inlets and air outlets at both ends of the exhaust pipe body, the exhaust pipe body is sequentially provided with a three-way catalytic converter and Filter muffler.

In this utility model, different from the prior art, there is no need to add a special purification device at the outlet of the exhaust pipe, but a three-way catalytic converter is directly integrated on the exhaust pipe to catalyze and filter the harmful gas discharged at the beginning. , At the same time, after the first filtration, an additional filter muffler is installed, and then the second gas filtration and noise reduction are performed, which plays the role of energy saving, environmental protection and noise reduction.

Preferably, the three-way catalytic converter is arranged near the air inlet, and the distance between the three-way catalytic converter and the air intake is smaller than the distance between the three-way catalytic converter and the filter muffler.

In the utility model, the distance between the three-way catalytic converter and the air inlet is smaller than the distance between the three-way catalytic converter and the filter muffler, which helps to buffer and transport the harmful gas for a certain distance after the first transformation and filtration, so that the exhaust rate After being slowed down, it enters the filter muffler, which helps to fully filter the exhaust gas and reduce noise for the second time.

Preferably, the filter muffler includes a network pipe main body with the same diameter as the pipe body and sound insulation cotton wrapped outside the network pipe main body.

In the utility model, when the air flow passes, the main body of the network pipe and the sound insulation cotton in the noise reduction filter will filter the passing air again to reduce noise, thereby reducing noise and protecting the environment.

Preferably, the main body of the network pipe is provided with a plurality of fine holes at equal intervals.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Example:

As shown in Fig. 1 and Fig. 2, an energy-saving and environment-friendly muffler exhaust pipe includes an exhaust pipe body 1, an air inlet 2 and an air outlet 3 at both ends of the exhaust pipe body 1, and the exhaust pipe body 1 is A three-way catalytic converter 4 and a filter muffler 5 are arranged in sequence from the air intake to the air outlet.

The three-way catalytic converter 4 is arranged near the air inlet 2 , and the distance between the three-way catalytic converter 4 and the air inlet 2 is smaller than the distance between the three-way catalytic converter 4 and the filter muffler 5 .

The filter muffler 5 includes a network pipe main body 51 with the same diameter as the pipe body and sound-insulating cotton 52 wrapped outside the network pipe main body.

The working principle of the utility model: after the exhaust gas enters from the exhaust pipe inlet, it is first catalyzed and filtered through the three-way catalytic converter to form the first filtration and purification, and then the second filtration is performed through the main body of the filter muffler and the sound insulation cotton Purify and reduce noise, finally discharge harmless gas, energy saving and environmental protection.
