Description
Technical field
The present invention relates to a kind of regulation method of stainless steel polishing dust, especially relate to the recovery method of heavy metal in the collection of stainless steel polishing dust and dust.
Background technology
Polishing is that indispensable operation produced by stainless steel ware, certainly leads to the dust comprising polish abrasive and stainless steel scurf in a large number during polishing.Polish abrasive is rich in chromium oxide particulate, and stainless steel scurf is rich in the heavy metals such as nickel, molybdenum, titanium.These polishing dusts enter air, water, soil, cause severe contamination to surrounding enviroment, and enter human body by all means, grievous injury health.At present, have although domestic some producers have employed to configure dust mask to operating personnel, install powerful exhaust system, dust arranges net collection, dust concentrates the methods such as landfill, prevention effect is still very undesirable.In addition, in polishing dust, contained a large amount of useful heavy metal also fails to be recycled and to utilize.And external way stainless steel ware surface treatment being taked to passivation and sandblasting, avoid polishing problem.
Summary of the invention
For solving the problem of above-mentioned stainless steel polishing dust pollution, the present invention mainly utilizes the equipment such as adsorbing powder dust case, filtering ponds, fractionating column, by the polishing dust that produces when producing stainless steel ware by absorption, collect, filter, the technological process such as heavy metal recovery in fractionation and dust, reach the pollution that stainless steel polishing dust can be avoided environment, the object heavy metal in dust can recycled again.
Object of the present invention is achieved by following technical proposals:
A regulation method for stainless steel polishing dust, comprises the following steps:
(1) utilize airduct to suck stainless steel polishing dust, after being collected by adsorbing powder dust case, form muddy and inject collecting bag, then through overstocking into block.
(2) dust briquetting is put into first filtering ponds, after the stirring that adds water, precipitation, dust mud is divided into three layers significantly: top layer is the cloth bits of carbon, wood chip and polishing wheel in water, polish abrasive; Intermediate layer is the powder slurry of iron content, nickel, molybdenum, titanium; Bottom is black oxidation chromium abrasive material.
(3) with brush row the polishing wheel cloth on upper strata consider, carbon in wood chip and polish abrasive removes, and with the discharge outlet discharge of water above filtering ponds.
(4) open the plasma discharge mouth below filtering ponds, draw the mud of intermediate layer iron content, nickel, molybdenum, titanium, and imported in second filtering ponds, then the stirring that adds water, precipitation, forms three layers.
(5) again after the program identical with step (3), the powder slurries such as the iron content in intermediate layer, nickel, molybdenum, titanium are discharged by plasma discharge mouth, imports in the 3rd filtering ponds, then the stirring that adds water, precipitation, forms three layers again.
(6) again after the program identical with step (3), the powder slurries such as the iron in intermediate layer, nickel, molybdenum, titanium are discharged by plasma discharge mouth, send into fractionating column.
(7) in fractionating column, inductively-coupled plasma spectrometer is installed, spectrum analysis is carried out to the powder slurry entered in tower, measure characterization of molecules spectral line and be recorded in the characterization of molecules spectral line electronic tag on capsule, characterization of molecules spectral line electronic tag on each capsule and iron standard molecule characteristic spectral line label, heavy metal nickel molybdenum titanium standard molecule characteristic spectral line label are compared by electronic eyes by intelligence spectrum read-write instrument, divide select tap a blast furnace, the mixture of nickel molybdenum titanium, iron and nickel molybdenum titanium and impurity totally four kinds of powder boxes.Four class powder boxes separate by the structure of selecting a good opportunity that divides controlled by intelligent spectrum read-write instrument, and iron powder box, nickel molybdenum titanium valve box and impurity powder box are exported fractionating column from delivery outlet.Simultaneously, the mixture of iron and nickel molybdenum titanium is distributed in the capsule of the ring-like conveyer belt of the second layer again, repeat the program of ground floor conveyer belt, so successively fractionation, after first fractionating column fractionation repeatedly of totally ten layers, the mixture of iron higher for purity and nickel molybdenum titanium is exported from delivery outlet, enters second fractionating column.
(8) in second fractionating column, after the program identical with first fractionating column, the mixture of iron higher for purity and nickel molybdenum titanium is imported to the 3rd fractionating column.
(9) in the 3rd fractionating column, after the program identical with first fractionating column, the nickel molybdenum titanium mixture that purity reaches 98% can finally be obtained.
(10) recovery of heavy metal nickel molybdenum titanium mixture.
Described adsorbing powder dust case by casing, high speed Powerful exhaust fan, electrostatic generator, wire netting, be used for producing the water pipe of cascade, air inlet and funnel and form.
Described filtering ponds are provided with mixer, observation window, discharge outlet and plasma discharge mouth.
Described fractionating column is provided with: the ring-like conveyer belt of capsule, inductively-coupled plasma spectrometer, intelligent spectrum read-write instrument, electronic eyes, iron standard molecule characteristic spectral line electronic tag, nickel molybdenum titanium standard molecule characteristic spectral line electronic tag, mechanism for sorting and delivery outlet are housed.
The electronic tag that can record characterization of molecules spectral line described capsule is equipped with.
The invention has the beneficial effects as follows: by designing efficient stainless steel polishing adsorbing powder dust case, utilize the methods such as the stop of negative-pressure adsorption, wire netting, Electrostatic Absorption and cascade wash away, the most of polishing dust produced during stainless steel polishing operation can be adsorbed, collects, greatly reduce polishing dust to the injury of human body.In addition, the heavy metals such as the nickel in polishing dust, molybdenum, titanium are reclaimed by filtration and fractional method by the present invention.Dust collects from stainless steel polishing ejecta, its nickel, molybdenum, titanium proportioning each other, just meet stainless steel material and smelt the requirement of additive, the heavy metal powder therefore fractionated out not only does not pollute the environment, and can be used as valuable raw material and be supplied to stainless steel smelting enterprise and re-use.
