The invention provides a waste gas filtering system and filtering method.The waste gas filtering system comprises a filtering device, a separation chamber and a back flushing device, the separation chamber and the back flushing device are connected with the filtering device, waste gas to be treated enters the filtering device through the separation chamber to be filtered, gas in the waste gas to be treated is discharged, and solid particles are intercepted; the reverse blowing device is used for introducing reverse blowing gas into the filtering device, solid particles in the filtering device move towards the direction close to the separation chamber, the first heating device is used for heating the filtering device, the temperature of waste gas in the filtering device is within the range of 350-500 DEG C through the first heating device, and the waste gas is prevented from being coked. According to the waste gas filtering system and filtering method, the heating device is additionally arranged to heat waste
