Abstract
The invention discloses a waste gas purification system which comprises a pickling tank, a waste gas collection device and a waste gas treatment device, wherein the waste gas collection device comprises a fan, four baffle plates and a suction pipe arranged at the rear side of each baffle plate; the waste gas treatment device comprises an alkali liquor spray absorber, a first waste gas absorption tower, a second waste gas absorption tower, a preheater, a heat exchanger, a urea pyrolyzer and an SCR reactor; the preheater is connected with the heat exchanger; one end of the heat exchanger is connected with an exhaust chimney and the other end is connected with the urea pyrolyzer; the urea pyrolyzer is connected with the SCR reactor; and the SCR reactor is connected with the exhaust chimney through the heat exchanger. The purification effect of pickling the waste gas can be significantly improved, the denitration efficiency is greater than 98%, and the HF and sulfuric acid waste gas removal efficiency is greater than 99%.
Description
technical field [0001] The invention relates to the field of metal surface treatment, in particular to an exhaust gas purification system and a method thereof. Background technique [0002] Metal wire, such as carbon steel and stainless steel, is the main material for processing various standard parts, mechanical shaft parts, cold-drawn steel and various metal products. In the steel produced in the United States and Japan, wire accounts for about 8%. -10%, during the forming and heat treatment process of steel, oxide skin will be formed on the surface. This type of oxide skin has a dense structure and strong adhesion to the substrate. It contains Fe, Cr, Ni, a small amount of C and Si, and there may be Mn, Ti, Mo and W and other elements, the oxide structure is: ferrous oxide (FeO), iron oxide (Fe2O3), ferric oxide (Fe3O4), chromium oxide (Cr2O3), nickel oxide (NiO), silicon dioxide (SiO2), Chromium spinel (Cr2O3 FeO) and nickel spinel (Ni Fe2O3), etc. Stainless steel oxid...
