The invention discloses a waste gas purifying system of a high-pollution production process of enamelled wires. A filter baffle device has a left side surface and a right side surface which are communicated with each other. A plurality of gas exhaust holes are arranged in the filter baffle device in one or more of a W-like shape, a M-like shape or a V-like shape. The filter baffle device can reduce moving speed of the waste gas, and by means of the design of non-linear air holes and addition of an adsorption layer, particle impurities and organic pollutants in the waste gas are effectively removed, thereby greatly improving purification effects. The filter baffle device can be recycled just by being cleaned at certain time, so that the waste gas purifying system saves cost and is convenient to mount and maintain.
