Description
Technical field
The present invention relates to a kind of preparation method of natural zeolite activation processing environmental protection indoor-outdoor air cleanser.
Background technology
Natural zeolite (zeolite) is as a kind of the shape that has micropore canals and gap structure in the silicate nonmetallic ore moisture alkali or alkaline earth metal aluminosilicate mineral, and and have the porous mineral material of the adsorptive selectivity of ion exchangeable, can become nanoscale unit material arranged and generated assembled material in one dimension, two and three dimensions space media.The zeolite nano-pore of composite Nano unit physical property and zeolite cavity characteristic---metal ion and bunch group's assembled material are used in realization aspect clean room's inner air and outer air for it and have been laid good basis.
People are influenced by terrestrial gravitation being called atmospheric thermodynamics owing to centrifugal force with geocyclic atmosphere, atmosphere is in place, face of land density maximum.Along with highly increase become rapidly thin.The troposphere is very close with human relation.Especially in the main activities zone of 1-2 kilometer near the ground place atmosphere pollution, the troposphere is above to be stratosphere, intermediate layer, warm layer and mesosphere.Atmosphere is made up of multiple gases, can be divided into by its composition and do clean atmosphere, steam and particulate.Do clean atmosphere mainly by N, O, three kinds of gas compositions of Ar.They account for 99.94% of total gas volume.
In lower atmosphere layer.Steam also is an important component part, and the different of its concentration with geographic location and meteorological condition can change in a big way, and dry area can be reduced to 0.02%, and can be up to 0.46% on warm temperature ground.Doing clean atmosphere is the environmental key-element of people or biological existence, generally need suck 10-12m for each person every day
3Air is at 60-90m
2Carry out the gas exchange on the alveolar surface, suck O
2Discharge CO
2To keep normal physiological activity.
The factor that causes atmosphere pollution has natural cause, and human factor is also arranged.Natural cause refers to sweep the sand bed on ground, ash, the CO of volcano eruption ejection by strong wind
2Deng.The CO that forest fire produces
2, CO, NO
2And hydrocarbon.Human factor mainly is the pollutant that industrial or agricultural, transportation and life heating etc. are discharged.
Atmosphere pollution is meant the limit that can allow above environment when the pollutant levels that enter in the atmosphere, change the composition of normal atmosphere, destroy its physics, chemistry and ecological balance system, thus harm humans life, production, health, the phenomenon of harm natural resources and property, equipment.
Atmosphere pollution can be divided into acute effect and chronic effect to the harm of health.Acute effect has promptly shown the phenomenon that causes poisoning symptom after being meant the air inrush that human body polluted at short notice, and several acute hazardous events once took place in history.Chronic effect is meant human body under the long term of low concentration pollutant, the chronic hazard of generation.This harm often is difficult for noticeable, and be difficult to differentiate, its harm approach be pollutant and respiratory mucosa by touching, cardinal symptom is eye, schneiderian membrane irriate, chronic bronchitis, asthma lung cancer occur and increases the weight of the state of an illness such as hypertension, heart disease because of the physiological function obstacle.In recent years the countries in the world lung cancer morbidity rate and the death rate obviously rise, and particularly industrially developed country's growth is especially fast, and the city is higher than the rural area.Though the cause of disease of lung cancer imperfectly understands so far, a host of facts explanation air pollution is one of important paathogenic factor, and is certain positive correlation between air pollution degree and the resident's lung cancer mortality.
The existence of the polluter in the atmosphere is to be determined by physicochemical property of himself and forming process; Meteorological condition also plays a part certain.
Pollution sources can be divided into stationary source and mobile pollution source by existence form, and the former refers to factory chimney etc., and the latter refers to the vehicles.As automobile, train, aircraft, steamer etc.The generation form of pollution sources can be divided into the pollution and the communications and transportation of fuel combustion pollution, industrial products production process and pollute.Preceding two classes belong to stationary source, and back one class belongs to mobile pollution source.
The migration of atmosphere pollution is main relevant with distribution, discharge capacity, landform, landforms, the meteorological condition factors such as (wind direction, wind speed, atmospheric turbulance, atmospheric stabilities) of pollution sources with diffusion, same pollution sources are to same place, owing to the influence of meteorologic factor, the concentration that causes can differ tens times in different time.
Because under the modern life condition, it is more and more longer that people rest on the indoor time, the air quality of the therefore indoor local environment relevant with the people is more even more important than the influence of outside atmosphere with health affected to people's life.Yet, factors such as the pollution sources that the mankind are direct and factors such as indirect activity, interior decoration and use article cause introducing in the local environment and ventilation are not smooth make the air of local environment usually be in pollutional condition, have therefore formed the serious harm of and operate as normal and life healthy to people.
At present, the air pollution of radical cure and elimination local environment is subjected to extensive concern always.The airborne major pollutants of local environment comprise the gas with foreign flavor (hydrogen sulfide, amine, mercaptan etc.) that forms because of factors such as human metabolic activity and food spoilages and harmful bacteria (Escherichia coli and staphylococcus aureus etc.) and adorn the pernicious gases such as formaldehyde, benzene, benzene series thing and ammonia that compound in horizontal material and the furniture material discharges formation because of interior decoration, obviously, should be able to remove pernicious gas and harmful bacteria simultaneously to the improvement of local environmental air pollution.
With the natural zeolite is carrier, and passing hole channel suction-operated activation, antibacterial components are assembled in nano pore and the inorganic anti bacterial type eliminating smell agent that has inorganic antibacterial and adsorb function of odor removal fast of technology such as stable curing preparation can become the purified product of local environment air such as room, toilet, automobile cab and refrigerator.
One of three broad aspect of atmosphere pollution main source and two are fuel combustions, comprise the billowing black smoke that chimney discharged, Industrial Boiler, civil boiler and the little cooking stove of industrial and mining enterprises.And the dirt, cigarette, the waste gas that are produced in industrial and mining enterprises' production process.These two classes pollution sources are referred to as stationary source.According to department of China office statistics eighties, these two atmosphere pollution ratios that the aspect produced are respectively 70% and 20%, have occupied 90% height of the whole source of atmospheric pollution.Yet in direct burnt fuel, coal fire discharged pollutant accounts for 96% of fuel combustion.The main source that is China's atmosphere pollution is a fuel, particularly is the industrial and mining enterprises of fuel with the coal.
