Description
Technical field
The present invention relates to a kind of processing system for removing the metallic nickel in metallurgical industry waste gas, belong to useless in environmental protection
Gas disposal field.
Background technology
Nickel is a kind of silvery white, hard and have ductility and have ferromagnetic metallic element, and it high polish and can resist
Corrosion.Nickel belongs to siderophile element, and its content highest in the earth's core, its form is natural dilval.The iron magnesium in the earth's crust
Matter rock is nickeliferous higher than sa rock, nickeliferous 1000 times for granite of peridotite, nickeliferous 80 times for granite of gabbro.
The chemical property of nickel is more active, but than iron stabilization.It is difficult to aoxidize in atmosphere during room temperature, is difficult anti-with concentrated nitric acid
Should.Thin nickel wire is flammable, is reacted with halogen during heating, and the slow mechanism dissolved in diluted acid can absorb a considerable amount of hydrogen.Nickel is not dissolved in
Water, surface forms the oxide-film of densification in humid air under normal temperature, and base metal can be prevented to continue to aoxidize.Can delay in diluted acid
Slow dissolving, discharges hydrogen and produces green positive bivalent nickel ion Ni2+；Resistance to highly basic.Nickel can burn in pure oxygen, send
Dazzling white light.Likewise, nickel can also burn in chlorine and fluorine gas.To oxidizing agent solution including including nitric acid, not occurring
Reaction.
Metallic nickel is mainly for the production of alloy（Such as nickel steel and nickeline）And as catalyst（Such as Raney nickel, espespecially as hydrogen
The catalyst of change）, currency etc. being may be utilized in fabricating, nickel plating can be prevented from getting rusty on other metals.Nickel is mainly used to manufacture not
Rust steel and other corrosion-resisant alloys, such as nickel steel, nickel-chromium steel and various non-ferrous alloys, nickeliferous composition corronil higher,
It is just not perishable.Nickel also make hydrogenation catalyst and for ceramic, Specialty Chemical vessel, electronic circuit, glass coloration and
Nickel compound preparation etc..
, almost without acute toxicity, general nickel salt toxicity is relatively low, but carbonyl nickel can produce very strong poison for metallic nickel
Property.Carbonyl nickel is absorbed rapidly by respiratory tract in vapour form, also can on a small quantity be absorbed by skin, and the former is that operating environment toxicity is invaded
Enter the main path of human body.Carbonyl nickel is 3.5 μ g/m in concentration3When will make one to feel the stink just like lamp black, during low concentration
People has uncomfortable sensation.Acute poisoning can be caused after absorbing carbonyl nickel, initial symptoms just occur within 10 minutes or so, such as：Dizzy, head
Pain, instability of gait, sometimes Nausea and vomiting, uncomfortable in chest；Later stage symptom be contact 12 to 36 hours after occur again Nausea and vomiting,
High fever, expiratory dyspnea, chest pain etc..There is Acute Chemical pneumonia during contact high concentration, pulmonary edema and respiratory tract finally occur
Circulatory failure and lethal die.
At present, the widely used nickeliferous metallurgic waste gas processing method of China mainly has dry method, wet method, filtering and electrostatic
4 classes, most commonly sack cleaner（Filtering）, cyclone dust collector（Dry method）, bubble dust collector（Wet method）Deng.With to removing
The raising of dirt efficiency requirements, electrostatic precipitation also progressively begins to use.

Nickeliferous particulate matter in bubble capture gas, grit is discharged with liquid, is purified waste gas, mainly includes that atomizing washing is removed
Dirt device, cyclone washer deduster, Venturi scrubbing deduster etc..Its advantage be treatment effeciency it is higher, suitable for treatment high temperature,
High humidity, inflammable, explosive waste gas, but the shortcomings of have that construction cost is big compared with high, floor space, easily cause secondary pollution.
（3）Filtration treatment：
Filtration treatment is mainly makes the waste gas containing nickel particle thing by porous filter-material, and nickel particle thing therein is retained down,
Waste gas is purified, it is main including self-filtering formula deduster, outside filtration dust catcher, fiber bag precipitator etc..Its is excellent
Point is that treatment effeciency is high, technology simple, but is not suitable for treatment high temperature, oil-containing or sticky waste gas.
（4）Electrostatic Treatment：
Electrostatic Treatment mainly uses the electrostatic attraction produced by high voltage electric field to act on, and nickeliferous particulate matter is separated with waste gas, main
Will be including tube-type esp, Elex precipitator etc..Its advantage is that treatment effeciency is very high, equipment resistance is small, energy consumption is low, resistance to height
Temperature, but have that construction cost is high, occupation area of equipment big, the shortcomings of being not suitable for medium-sized and small enterprises and use.
At present, the nickeliferous waste gas processing method that China generally uses, generally existing construction cost is high, floor space is big, suitable
The shortcomings of answering property is poor, treatment effect is undesirable.Therefore, it is necessary to break away from existing Treatment process route, purified treatment is hewed out
The new way of nickeliferous metallurgical industry waste gas, and then develop a kind of nickeliferous metallurgical industry waste gas purification treatment technology of new type.
