The invention relates to the technical field of gas filtering, in particular to an annealing furnace gas filtering device which comprises a gas main pipe and a furnace body fixedly connected to one end of the gas main pipe in a communicated mode. The Y-shaped filter is arranged in the middle of the gas main pipe; the pressure controller and the pressure sensors are started, the pressure sensors sense the flow pressure on the two sides of the Y-shaped filter respectively, when the pressure difference is large, the data difference on the pressure gauge becomes large, the pressure gauge transmits data to the pressure controller, and the pressure controller is controlled by a program and starts an alarm to remind a worker to clean a filter element. Meanwhile, the pressure controller closes the second control valve and opens the first control valve through a program, so that the coal gas is controlled not to circulate from the coal gas main pipe but circulate from the coal gas branch pipe, and coal gas conveying i
