Description
Technical field
The present invention relates to a kind of air pollutants sweep-out method, more particularly to a kind of finishing pollution sweep-out method, belong to empty
Gas purification techniques field.
Background technology
Finishing pollution is emerging environmental pollution, and source is a lot, is used not in fitment process mainly due to people
What qualified finishing material and irrational design were caused.It can be divided into formaldehyde pollution, benzene pollution, ammonia according to pollutant kind
Pollution, Radon pollution, lead contamination etc..These pollutants are mixed in atmosphere, enter human body by respiratory tract, human body are produced various
Harmful effect.It is said that these indoor air pollutants of radon, benzene, formaldehyde, ammonia, trichloro ethylene can cause the breathing of human body 35.7%
Tract disease, 22% chronic lung disease and 15% tracheitis, bronchitis and lung cancer are multisystem caused by it, multiple organ, many
Tissue, many cells, polygenic infringement, potential healthy hidden danger is brought to human body.
To avoid the infringement of finishing pollution, it should avoid using the material containing harmful substance when choosing finishing material, adopt
With the green building material for meeting national standard.At the same time it can also remove the pollution that finishing is produced from adsorbent.Adsorbent has big
Ratio surface, suitable pore structure and surface texture, have strong adsorption capacity to adsorbate, typically not with adsorbate and medium
Chemically react, pollutant component can be made to be attached to its particle surface.Conventional adsorbent has using carbonaceous as the various of raw material
Acticarbon and metal, nonmetal oxide class adsorbent (such as silica gel, aluminum oxide, molecular sieve, natural clay), most
Representational adsorbent is activated carbon.
Activated carbon relies primarily on therein small hole and pollution molecule is absorbed, and still, absorption is not true
Positive removal, absorbs and simply pollutant is stored in the hole of activated carbon, and what pollutant still existed always.And due to work
Property charcoal hole quantity be limited, pollution molecule outwards release generally up to several years, the suction of activated carbon after usual one month
Attached amount, which just progressivelyes reach the activated carbon after saturation state, saturation, can not continue to absorb pollutant, or even also have the dirt adsorbed
Dye thing outwards discharges, or, after temperature is more than 24 DEG C, the gas adsorbed on activated carbon also can be discharged progressively, cause two
Secondary pollution.So general comprehensive statistics be charcoal absorption efficiency less than 50%, premise still adsorbed after immediately by activated carbon
