Treatment system for purifying industrial waste gas

Abstract

The invention discloses a treatment system for purifying industrial waste gas. The system is mainly used for removing metal nickel from waste gas of metallurgical industry. The system comprises an anti-shock protector, a multi-parameter gas tester, an alkali washing and deacidification device, a front-end induced draft fan, a double-magnetic-moment alternating catalytic-nickel oxygen cluster synthesis separation and purification device, an electrostatic dust remover, a wet gas purifier and a tail-end induced draft fan. The system transforms various forms of nickel elements in the waste gas are transformed into nickel protoxide (NiO) by creatively utilizing the chemical characteristic that metal oxide can be chemically combined into metal oxygen cluster under the catalytic action of a multi-magnetic-moment alternating magnetic field, the nickel protoxide is a double-magnetic-moment alternating magnetic field which is generated by oppositely rotating and superposing two sets of U-shaped electromagnet, the nickel protoxide in the waste gas is converged under the catalytic action of the alternating magnetic field to produce the nickel oxygen cluster at the moment, and specific metal oxide is used for capturing hydrazine to capture and remove the nickel oxygen cluster from the waste, so that the purpose of performing purification treatment on the nickel-containing waste gas 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.
