An energy-saving and environmentally friendly air preheating device for coal-fired boilers is disclosed. The device includes a base plate, preheating pipes, baffle blocks, and gas flow components. The preheating pipes are connected to the top of the base plate, and the gas flow components are mounted on the preheating pipes. A baffle block is rotatably connected to the lower left side of the preheating pipes. The device also includes manifolds, baffles, and flue gas guide plates. Baffles are connected to both the upper and lower sides of the preheating pipes, and manifolds are evenly spaced and densely distributed between the baffles. Flue gas guide plates are slidably connected between the upper and lower sides of multiple manifolds. This invention, when using boiler flue gas after combustion to heat air, can filter out the waste residue from the hot flue gas and use the heat from the waste residue to heat the air, increasing the utilization rate of flue gas thermal energy.
