Problems solved by technology

[0004] The four types of mufflers mentioned above can only play a single role in reducing exhaust noise. They are not completely from the perspective of protecting the environment, and cannot reduce and treat the temperature and pollutants of the exhaust gas. The function is single.

Embodiment 1

[0016] Example 1: See figure 1 , figure 2 , image 3 , a muffler that can reduce the exhaust temperature, including a muffler housing 3, an exhaust pipe 8 is arranged inside, and an exhaust pipe 8 is composed of a first exhaust pipe 8-1 and a second exhaust pipe 8 -2 components, a water spray device 5 is provided between the first exhaust pipe 8-1 and the second exhaust pipe 8-2. The full contact between the exhaust gas and the water droplets transfers most of the heat to the water droplets.

[0017] Described water spray device 5, is provided with the core cylinder 4 coaxial with exhaust pipe 8 in its middle, is provided with annular pipe 5-2 outside core cylinder 4, is evenly distributed on annular pipe 5-2 The water spray pipe 5-1; the annular pipe 5-2 communicates with the water inlet 5-3 located on the muffler housing 3.

[0018] It also includes a mixing chamber 12 between the second exhaust pipe 8-2 and the exhaust port 6, and a cooling hole 2 is provided on the mu...

Abstract

The invention discloses a silencer capable of reducing the temperature of exhaust gas, and relates to a silencer, in particular to silencers for power plants with internal combustion engines and vehicles. The silencer comprises a silencer shell (3), wherein a gas exhaust pipe (8) is arranged in the silencer shell. The silencer is mainly characterized by comprising a gas exhaust pipe (8) which consists of a first gas exhaust pipe (8-1) and a second gas exhaust pipe (8-2); and a water spraying device (5) is arranged between the first gas exhaust pipe (8-1) and the second gas exhaust pipe (8-2). The silencer has the advantages that noise is reduced during gas exhaust, the temperature of exhaust gas is reduced, inhalable particles and partial harmful gas in tail gas are reduced, and heat pollution and environmental pollution which are caused during gas exhaust are avoided.

Description

technical field [0001] The invention relates to the structure of the muffler, and mainly relates to the structure of the muffler used in internal combustion engine power stations and vehicles. Background technique [0002] After years of development, traditional mufflers have become more and more diverse, with different principles, forms, and specifications. The various common mufflers basically belong to four types: resistive, resistive, compound and exhaust. [0003] The resistive muffler is a muffler that uses porous sound-absorbing materials of different structures in the airflow pipeline to absorb sound energy and reduce exhaust noise; the resistive muffler reflects part of the sound waves back to the direction of the sound source through the sudden change of the acoustic characteristics in the pipeline to achieve The muffler for the purpose of muffler; the composite muffler is designed by combining different muffler principles such as resistance and resistance to form...
