Description

Technical Field

[0001] This utility model relates to a waste gas treatment device, specifically a skid-mounted adsorption concentration and catalytic combustion combined waste gas treatment device. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life, particularly from chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries, as well as from domestic waste gas generated by human activities. These emissions are characterized by strong odors, severely polluting the environment and impacting human health. Waste gas contains a wide variety of pollutants with complex physical and chemical properties and varying degrees of toxicity. For example, fuel combustion emissions contain sulfur dioxide, nitrogen oxides, and hydrocarbons. Different raw materials and processes in industrial production result in the emission of various harmful gases and solid wastes, containing components such as heavy metals, salts, and radioactive substances. Automobile exhaust contains hydrocarbons such as lead, benzene, and phenols.

[0003] The typical treatment process for exhaust gas is as follows: paint mist passes through the water curtain plate of the paint booth and then through the spray tower for spraying. After filtration by a filter, it is purified by a photocatalytic oxidation purifier and an activated carbon exhaust gas purifier. Finally, it is discharged from the flue through a fan. This process can meet the standards if the activated carbon is frequently replaced in a short period of time and the fan air volume is matched with the pretreatment equipment. However, if the activated carbon is not frequently replaced or the fan air volume is not matched with the pretreatment equipment, it will not meet the emission standards and will also cause secondary pollution.
