The reactive muffler comprises a shell, a muffling pipeline, a first partition plate, a micro-perforated pipe, a first guide pipe and a first spraying part, the muffling pipeline penetrates into the shell in the axial direction of the muffling pipeline, and a cooling cavity is formed by the outer wall of the muffling pipeline and the inner wall of the shell; the silencing pipeline comprises an air inlet pipe and an air outlet pipe; the first partition plate is arranged in the silencing pipeline and divides the interior of the silencing pipeline into a first-stage silencing cavity and a second-stage silencing cavity. The air inlet pipe communicates with the first-stage silencing cavity, and the air outlet pipe communicates with the second-stage silencing cavity. The micro-perforated pipe is arranged in the secondary silencing cavity in the axial direction, and one end of the micro-perforated pipe is connected to the first partition plate. Micropores are formed in the micro-perforated pipe; the first guide pipe
