The exhaust gas has a strong odor, seriously polluting the environment and affecting human health. In order to purify the exhaust gas and avoid exhaust gas pollution, when the exhaust gas is discharged, the harmful substances in the exhaust gas must be purified through the exhaust gas treatment and purification device.
