Zusammenfassung:	The utility model provides a device for reducing hot blast heater waste gas diffusion noise. The device for reducing the hot blast heater waste gas diffusion noise comprises diffusion branch pipes connected with a hot blast heater, diffusion stop valves arranged on the diffusion branch pipes, a diffusion main pipe connected with the diffusion branch pipes, a diffusion chimney connected with the diffusion main pipe, and a diffusion silencer arranged between the diffusion main pipe and the diffusion branch pipes. The device for reducing the hot blast heater waste gas diffusion noise can reduce waste gas diffusion noise and avoid secondary pollution because of waste gas diffusion, and device maintenance is simple and convenient. Meanwhile, the problems that normal operation of the hot blast heater is affected due to the fact the waste gas diffusion stop valve is completely closed because components on the diffusion silencer fall off and the like can be avoided.
