Abstract
The present invention relates to waste gas pollution control and treatment field, and in particular to a kind of tobacco remover and preparation method thereof.Oxidant is added in processing method of the invention, it is ensured that either NO2Or NO can be absorbed by tobacco remover, there is no new tobacco generation.
Description
Technical field
The present invention relates to waste gas pollution control and treatment field, and in particular to a kind of tobacco remover and preparation method thereof.
Background technology
Strip is the indispensable procedure in electroplating technology, and current overwhelming majority electroplating enterprise is all to use nitric acid
Salt as oxidant electroplating technology.Using the oxidisability of nitrate ion, the dissolving metal on plating piece is peeled off, so as to reach
Strip the purpose of coating.Enter in solution when metal is oxidized to metal ion, nitrate ion is reduced generation NO and NO2Gas
Body, is discharged into the smog of formation yellow in air, is commonly called as " tobacco ".Health of the tobacco not only to the operative employee of strip has directly
Harm, it is often more important that the nitrogen oxides of high concentration gets into the air a series of more extensive harm that can also cause, such as broken
Bad ozone layer, formed acid rain, be attached on dust into human body respiratory tract.Therefore during having to efficiently control strip
The tobacco of generation.
Traditional method is that the tobacco that will be produced in strip enters spray column by collecting, by spraying into NaOH
Solution, absorbs a part of NO_x formation sodium nitrate so as to realize reducing the purpose of tobacco.Specific reactive chemistry equation is such as
Under：
3NO2+2NaOH=2NaNO3+NO+H2O
Traditional method has two for the absorption of tobacco：One is that NO in tobacco can not be by sodium hydroxide solution
Absorbed；Two is NO2NO gases can be still produced after being absorbed by sodium hydroxide solution, NO gases get into the air can be oxidized to
NO2.Specific reactive chemistry equation is as follows：
2NO+O2=2NO2
Someone once attempts absorbing tobacco using urea liquid, although urea absorption NO2Efficiency is very high, but urea is to NO assimilation effects
It is limited, can not thoroughly solve the problems, such as tobacco.
The content of the invention
For many deficiencies of the prior art, it is an object of the invention to provide a kind of tobacco remover and preparation side
Method, the technical scheme that it is used is as follows：A kind of tobacco remover, it is characterised in that：By the material mixing of following mass fraction
Into：1 part of NaOH, 0.2~0.6 part of oxidant, 0.03~0.08 part of stabilizer.
Described oxidant is any one in sodium perchlorate, sodium chlorate, sodium chlorite, SODIUM PERCARBONATE, sodium peroxydisulfate
Or combinations thereof.
Described stabilizer is, any one or they in sodium carbonate, Boratex, sodium sulphate, sodium nitrate, sodium acid carbonate
Combination.
The beneficial effects of the invention are as follows：
Oxidant is added in processing method of the invention, it is ensured that either NO2Or NO can be absorbed by tobacco remover,
There is no new tobacco generation.By taking oxidant sodium chlorate as an example, specific reaction equation is as follows：
6NaOH+6NO2+NaClO3=NaCl+6NaNO3+3H2O
2NaOH+2NO+NaClO3=NaCl+2NaNO3+H2O
The processing method need not increase new equipment, and tobacco remover adds original sodium hydroxide solution storage tank, raw material
Wide material sources, total reagent cost is cheap, and the removal efficiency to tobacco is very high, with the practical feasibility promoted.
