The first SO2 sensor is used for detecting the concentration of SO2 in air after being filtered by the activated carbon filter layer, the humidity sensor is used for detecting the air humidity in the dust removal cavity, the ultrasonic sensor is used for detecting pressure waves or sound waves generated when the air passes through filter holes of the filter screen, the electric heating dehumidifier is used for reducing the air humidity in the dust removal cavity, the rotating speed detector is used for detecting the rotating speed of the turbofan, the central controller can control the operating speed of the turbofan through the frequency converter, a set data range is stored in the data storage device, and the central controller compares a numerical value detected by the first detection device with the data storage device to judge whether the device is abnormal in operation or not;

although the activated carbon filter layer can filter SO2 gas, most of SO2 gas is not filtered by the activated carbon filter layer due to the influence of the water vapor content in the air, sulfurous acid or sulfuric acid is formed by combining with the water vapor and is attached to the surface of a part of the dust removal cavity, the air humidity in the dust removal cavity can be reduced through the electric heating dehumidifier, the SO2 gas is prevented from being combined with the water vapor in the air to form sulfuric acid or sulfurous acid, the probability of adsorption of the SO2 gas by the activated carbon filter layer is increased, and the concentration of the SO2 gas in the air is effectively reduced; when the detected air humidity is lower than or in the set interval, the central controller does not control the operation of the electric heating dehumidifier, and if the detected air humidity is higher than the set interval, the central controller controls the operation of the electric heating dehumidifier, so that the waste of energy can be reduced;

because the air can form the vortex when passing through the mesh on the filter screen, and the shock change of vortex can produce pressure wave or sound wave, the ultrasonic wave converts this sound wave into the signal of telecommunication, with this flow that can judge the gas that passes through between the filter screen, when ultrasonic sensor detected that filter screen department circulation of air speed is less than the setting value, it blocks up to explain filter screen mesh appears, central controller control converter reinforcing turbofan's rate of rotation, promote the air flow in the ventilation hose, guarantee dust collector's dust removal rate, when rotational speed detector detected turbofan's rate of rotation is higher than the setting range, the air flow of filter screen department still is less than the setting value, it is serious to explain the mesh jam condition of filter screen, in time, need to change.
