Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, in particular to a muffler fire prevention device. Background Art

[0002] Muffler generally refers to silencer. Muffler refers to the airflow duct with noise transmission at the same time. It can use pipes and elbows with sound-absorbing lining or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance to reduce the noise in the pipe. According to the Occupational Safety Law, the engine exhaust emission system used at the oilfield construction site must be equipped with fire prevention equipment to prevent fires in oil and gas wells, causing major economic losses and casualties. However, the exhaust gas of the engine used on the oilfield workover rig is currently discharged through the exhaust pipe and silencer. Although the silencer has the effect of reducing noise, it is difficult to eliminate the sparks contained in the exhaust gas. Especially under heavy load or engine carbon deposition, afterburning and other fault conditions, the sparks contained in the exhaust gas are easy to cause fire accidents at the oil and gas construction site.
