The invention relates to an exhaust gas treatment device and method. The device comprises a first exhaust gas treatment tower, a second exhaust gas treatment tower and an exhaust gas inlet pipe. The exhaust gas inlet pipe is connected to a gas inlet of the first exhaust gas treatment tower through a first pipeline, and a gas outlet of the first exhaust treatment tower is connected to a gas inlet of the second exhaust gas treatment tower through a second pipeline. A first branch goes out from the exhaust gas inlet pipe, so that the exhaust gas inlet pipe communicates with a second pipeline. A first valve is arranged on the first pipeline, a second valve is arranged on the first branch, a third valve is arranged on the second pipeline and close to a gas outlet of the first exhaust gas treatment tower, and the second valve is separately connected to the first valve and the third valve. A detection device is arranged on the exhaust gas inlet pipe, is used for detecting acid-base property of exhaust gas in the exhaust gas inlet pipe and is connected to the second valve for communication. The exhaust gas treatment device provided by the invention is simple in structure, and not only can effectively treat acidic and alkali exhaust gas, but also is good in flexibility, and the operating cost can be greatly lowered.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment device and method. Background technique [0002] Waste gas treatment mainly refers to the work of treating industrial waste gas such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases generated in industrial places. Common waste gas treatment includes factory smoke and dust waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc. The commonly used methods are: water absorption method, aerated activated sludge deodorization method, multi-media catalytic oxidation process, because the exhaust gas pollutes the air very seriously, therefore, the environmental protection department has formulated strict requirements for the exhaust gas treatment of chemical plants, requiring Discharge can o...
