Treatment system for purifying industrial waste gas

Abstract

The invention discloses a treatment system for purifying industrial waste gas. The treatment system is mainly used for removing metallic nickel from the metallurgical industrial waste gas. The treatment system includes an anti-impact protector, a multi-parameter gas tester, an alkali cleaning deacidification device, a front-end induced draft fan, a double-magnetic-moment alternating catalysis-nickel oxygen cluster synthesis separation purification device, an electrostatic precipitator, a wet gas purifier and a tail-end induced draft fan. The treatment system creatively utilizes the chemical characteristic of metal oxides which can be combined into metal oxygen clusters under the catalytic action of a multi-magnetic-moment alternating magnetic field, nickel elements with various forms in the waste gas are first converted into nickel oxide (NiO) and then placed in a double-magnetic-moment alternating magnetic field produced by rotation and superposition of two sets of U-shaped electromagnets in the opposite direction, at the moment, the nickel oxide in the waste gas can be catalyzed by the alternating magnetic field to converge to form the nickel oxygen clusters, the nickel oxygen clusters can be removed from the waste gas by trapping hydrazine through specific metallic oxides, and thus the purpose of purifying treatment of the waste gas containing nickel is achieved.

Description

technical field [0001] The invention relates to a treatment system for removing metal nickel in metallurgical industry 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 dissol...

Problems solved by technology

Its advantages are high processing efficiency, small equipment resistance, low energy consumption, and high temperature resistance, but there are disadvantages such as high construction cost, large equipment footprint, and not suitable for small and medium-sized enterprises.

[0015] At present, the nickel-containing waste gas treatment method commonly used in my country has the disadvantages of high construction cost, large floor area, poor adaptability, and unsatisfactory treatment effect.
