Description
Technical field
The present invention relates to field of Environment Protection.It is more particularly related to a kind of novel nitrogen oxide adsorbent and system thereof
Preparation Method.
Background technology
Industrial waste gas controls nitrogen oxides (NO in processingx) pollution generally use improvement technique and equipment, improvement burning,
The method such as purified treatment and high chimney emission.Nitrogen oxides refers to only by nitrogen, two kinds of elementary composition compounds of oxygen.Common
Nitrogen oxides has nitric oxide (NO, colourless), nitrogen dioxide (NO2, rufous), laughing gas (N2O), dinitrogen pentoxide (N2O5) etc.,
Wherein except under dinitrogen pentoxide normality in solid in addition to, all in gaseous state gas leak detector under other nitrogen oxides normalities.As air
Nitrogen oxides (the NO of pollutantx) often refer to NO and NO2。
Nitrogen oxides (NOX) kind is a lot, including nitrous oxide (N2O), nitric oxide (NO), nitrogen dioxide (NO2)、
Nitrogen trioxide (N2O3), dinitrogen tetroxide (N2O4) and dinitrogen pentoxide (N2O5) etc. multiple compounds, but mainly NO and
NO2, they are common atmosphere pollutions.
Nitrogen oxides can stimulate pulmonary, makes the respiratory system disease of people's more difficult opposing flu etc, and respiratory system is problematic
Personage such as asthmatics, can be easier to be affected by nitrogen dioxide.For child, nitrogen oxides is likely to result in pulmonary and grows
Impaired.Research is pointed out to suck for a long time nitrogen oxides and be may result in pulmonary's structural change, but not can determine that yet at present cause this
The amount of nitrogen oxides of consequence and suction gas time.
It is that to form of photochemical fog and acid rain important former based on the nitrogen oxides of nitric oxide and nitrogen dioxide
Cause.Nitrogen oxides in vehicle exhaust irradiates the toxic smog formed that reacts, referred to as light with hydronitrogen through ultraviolet
Chemical fumes.
Photochemical fog has special odor, stimulates eyes, injures plant, and atmospheric visibility can be made to reduce.It addition, nitrogen
Oxide and the water in air react the nitric acid generated and nitrous acid is the composition gas leak detector of acid rain.Nitrogen oxidation in air
Thing is mostly derived from the burning of Fossil fuel and the burning of plant, and nitrogen-containing compound in agricultural land soil and animal excrements
Convert.
Industrial waste gas controls nitrogen oxides (NO in processingx) pollution generally use improvement technique and equipment, improvement burning,
The method such as purified treatment and high chimney emission.Purified treatment NO used at presentxMethod a lot, can be divided mainly into catalysis reduction
Method, liquid absorption method and absorption method three major types.
But absorption method is one of current most economical feasible method.
Summary of the invention
It is an object of the invention to provide one and newly imitate nitric oxide adsorbent, to overcome existing adsorbent weak effect etc.
Shortcoming, thus reduce air pollution index.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of novel nitrogen oxide adsorbent, including the component of following weight portion:
Activated carbon: 10～20 parts, calcium carbonate: 8～10 parts, calcium bicarbonate: 8～10 parts,
Zeolite powder: 5～10 parts, iron chloride: 5～10 parts, SODIUM PERCARBONATE: 8～10 parts,
Ammonia: 10～20 parts, sodium hypochlorite: 3～5 parts, water: 20～30 parts.
Preferably, described activated carbon is in wood activated charcoal, activated coco nut charcoal, active carbon from coal and activated coke
One or combination in any.
It is a further object to provide the preparation method of a kind of novel nitrogen oxide adsorbent, including walking as follows
Rapid:
Step (1): calcium carbonate, calcium bicarbonate, zeolite powder, iron chloride, SODIUM PERCARBONATE, ammonia and water are uniformly mixed；
Step (2): activated carbon is immersed in said mixture 10～12 hours, and dries；The most several times, until mixing
Thing is completely immersed in activated carbon；
Step (3): sodium hypochlorite is sprayed into activated carbon, dries, had both obtained novel nitrogen oxide adsorbent.
Compared with prior art, there is advantages that
(1) present invention is possible not only to have stronger nitrogen oxides removal effect, greatly reduces air pollution index；
(2) preparation technology is relatively easy, with low cost.
Detailed description of the invention
