Problems solved by technology

But for the muffler itself, its main function is to eliminate noise and exhaust gas, and the muffler of the above structure has multiple partitions in the cavity, and the axial directions of each guide tube are not on the same straight line. As far as airflow is concerned, the sound-absorbing baffle acts as a hindrance to the airflow, thus reducing the performance of the muffler

Abstract

The invention relates to a diesel engine muffler. The diesel engine muffler comprises a casing; one end of the casing is provided with an air inlet pipe; the other end of the casing is provided with an air outlet pipe; a hole plate and a catalytic converter are arranged in the casing; the outer circumferential surface of the hole plate is fixed on the inner circumferential wall surface of the casing; the hole plate is located between an air inlet end of the casing and the catalytic converter; the catalytic converter comprises a tubular carrier, a support and catalysts which coat the inner surface and the outer surface of the tubular carrier respectively; the tubular carrier is fixedly connected with the support; the support is fixedly connected with the inner wall surface of the casing. According to the diesel engine muffler, the noise elimination performance is improved and emissions of the harmful gas are reduced.

Description

technical field [0001] The invention relates to a diesel engine muffler. Background technique [0002] The muffler is a device that prevents sound transmission and allows airflow to pass through, and is an important measure to eliminate aerodynamic noise. The muffler is a noise reduction device installed on the airflow channel of aerodynamic equipment (such as blowers, air compressors, boiler exhaust outlets, generators, water pumps and other equipment with high exhaust noise) or in the intake and exhaust systems. . [0003] A diesel engine generator muffler is disclosed in the prior art, which includes a shell, an air inlet, an exhaust port 3, a muffler partition, a draft pipe, a cleaning hole and a sealing cover, and the air inlet and For the exhaust port, the shell 1 is provided with a noise-absorbing partition, and a guide pipe is fixed between the noise-absorbing partitions, and a cleaning hole is provided on one side of the casing, and a sealing cover is provided on ...
