Treatment method for purifying industrial waste gas

Abstract

The invention discloses a treatment method for purifying industrial waste gas. A system is mainly used for removing metal nickel in metallurgy industrial waste gas. The waste gas sequentially passes through an anti-impact protector, a multi-parameter gas tester, an alkali washing and deacidifying device, a front-end draught fan, a double-magnetic moment alternating catalysis-nickel oxygen cluster synthesis, separation and purification device, an electrostatic precipitator and a wet gas purifier to be treated. According to the treatment method disclosed by the invention, a chemical property that metal oxide can be compounded into a metal oxygen cluster under the catalysis effect of a multi-magnetic moment alternating magnetic field is creatively utilized, and a nickel element with various forms in the waste gas is converted into nickelous oxide (NiO); then the waste gas is located in a double-magnetic moment alternating magnetic field generated by rotating and stacking two sets of U-shaped electromagnets in opposite directions; at the moment, the nickelous oxide in the waste gas is collected under the catalysis effect of the alternating magnetic field to form a nickel oxygen cluster, and the nickel oxygen cluster is gathered and removed from the waste gas by utilizing a specific metal oxide gathering hydrazine, so that the aim of purifying and treating the nickel-containing waste gas is realized.

Description

technical field [0001] The invention relates to a treatment method for removing metal nickel in metallurgical industrial waste gas, which belongs to the field of waste gas treatment in environmental protection. Background technique [0002] Nickel is a silvery-white, hard, malleable, ferromagnetic metallic element that is highly polishable and corrosion-resistant. Nickel is an iron-loving element, and it has the highest content in the earth's core, and its form is a natural nickel-iron alloy. In the crust, the nickel content of ferromagnesian rocks is higher than that of silica-alumina rocks, the nickel content of peridotite is 1000 times that of granite, and the nickel content of gabbro is 80 times that of granite. [0003] Nickel is chemically active but more stable than iron. It is difficult to oxidize in the air at room temperature, and it is not easy to react with concentrated nitric acid. Thin nickel wire is combustible, reacts with halogens when heated, slowly diss...
