The invention discloses a safe, reliable, green and environment-friendly exhaust purification muffler. It includes the upper shell of the muffler, the lower shell of the muffler, the middle partition, the exhaust pipe and the outlet pipe. The middle partition is placed between the upper shell of the muffler and the lower shell of the muffler. , there is an air inlet pipe on the middle partition, one end of the air inlet pipe is connected to the exhaust pipe, the other end of the air inlet pipe communicates with the space formed by the lower shell of the muffler and the middle partition, and the other end of the middle partition near the air inlet pipe is set There is a catalytic device, and an inner bile pipe is provided on the middle partition. One end of the inner bile pipe is connected to the air outlet pipe, and the other end of the inner bile pipe communicates with the space formed by the upper shell of the muffler and the middle partition. A spark arrester is arranged in the air outlet pipe. The beneficial effects of the invention are: safety, reliability, environmental protection; good heat insulation effect, long service life; high noise reduction efficiency, good sound insulation effect; high air flow conversion efficiency, strong purification ability; stable and firm installation.
Description
technical field [0001] The invention relates to the related technical field of mufflers, in particular to an exhaust purification muffler. Background technique [0002] The muffler is a device that allows airflow to pass through, but can prevent or reduce sound transmission, and is an important measure to eliminate aerodynamic noise. The muffler can block the propagation of sound waves and allow airflow to pass through, which is an effective tool for noise control. There are many types of mufflers, but the muffler mechanism can be divided into six main types, namely resistive muffler, resistive muffler, impedance composite muffler, micro-perforated plate muffler, small hole muffler and active muffler. Most of the existing mufflers adopt the principle of impedance composite noise reduction. Due to complex structure, heavy weight, high-temperature oxidized sound-absorbing filler, high-speed airflow impacting sound-absorbing filler, water vapor permeating sound-absorbing fill...
