Abstract
A kind of water-permeable and air permeable of the present invention purifies air the production technique of pavior brick, belongs to traffic facilities technical field.Adopt industrial waste slag, coal gangue, zeolite, add the high-titanium dry slag higher than 10%, add the water glass of 1% soda ash and 2.5%, stir, calcining, adds low temperature bonding agent, compression moulding after stirring, then through sintering the microporous cellular of kapillary communicating pores into.The present invention can consume trade waste in a large number and produce water-permeable and air permeable and to purify air pavior brick, not only environmental pollution can be reduced, save large stretch of good farmland clay, turn waste into wealth, and the objectionable impurities that can absorb in a large number in degraded air, be not only and realize the effective way that high-level efficiency utilizes resource, also effectively reduce pollution simultaneously, purify air.
Description
Technical field
The invention belongs to traffic facilities technical field, particularly relate to a kind of water-permeable and air permeable and to purify air the production technique of pavior brick.
Background technology
China's topsoil is serious all the more, but due in China's environmental improvement, only water pollutions and the solid waste market degree of administering is higher, and all the other are as air contaminant treatment, be subject to weather effect and can shift between different geographical due to it.Therefore, the enthusiasm of government to air contaminant treatment is lower all the time, and this part market is also comparatively weak.
The loss that Chinese city atmospheric pollution causes mainly comprises: outdoor cause with room air pollution health impact (especially chronic bronchitis), the loss of crop that acid deposition causes and forest, material corrosion, high lead content causes the nervous system injury of children and intelligence to decline in particulate matter.Ministry of Health of China has assert that the respiratory tract disease of chronic obstructive is one of leading cause of the death of China, accounts for dead more than 1/4 according to statistics.
The source of atmospheric pollution can be divided into two natural and artificial large classes.Natural pollution source is formed due to natural cause (as volcanic explosion, hill fire etc.), and man-made pollution source is because people are engaged in production and life activity and being formed.In man-made pollution source, fixing (as chimney, industrial exhaust gas cylinder) and (as automobile, train, aircraft, the steamer) two kinds of movement can be divided into again.Due to man-made pollution source ubiquity, paid close attention to so carry out more people compared with natural pollution source.Air primary pollution source has:
(1) industrial enterprise of industrial enterprise is the main source of topsoil, is also one of emphasis of atmospheric hygiene protected working.Along with developing rapidly of industry, kind and the quantity of atmospheric polluting material are increasing.Due to character, scale, technological process, the difference such as raw material and product category of industrial enterprise, they are also different to the degree of topsoil.
(2) life cooking stove and heating boiler are in residential district, along with concentrating of population, a large amount of domestic life cooking stoves and heating boiler also need to consume a large amount of coal, the heating time especially in the winter time, often make contaminated area full of smoke, this is also a kind of source of atmospheric pollution that can not be ignored.
(3) communications and transportation in recent decades, and due to the development of communications and transportation cause, the automobile that city travels is increasing, and the passenger and freight transportations such as train, steamer, aircraft are frequent, and these add the new source of atmospheric pollution to city again.Wherein have have a strong impact on be automobile discharge waste gas.The feature of auto-pollution air is that the pollutent of discharging is very near apart from the breathing zone of people, can directly be sucked by people.Main containing carbon monoxide, oxynitride, hydro carbons (hydrocarbon polymer), lead compound etc. in the waste gas that car combustion engine is discharged.
According to the regulation of China's " ambient air quality ", that monitors every day and issue mainly contains three air pollutant indexs: pellet, nitrogen peroxide and sulfurous gas.The index of these indexs is excellent 0 ~ 50 time, is good when 51 ~ 100, and more than 100 for polluting." pellet " of the monitoring of standard regulation refers to that diameter is less than the particulate matter of 10 microns, but do not comprise " individual first watch is little ", be less than the particulate matter (be called for short " fine particle ", also known as PM2.5) of 2.5 microns.In above-mentioned three contamination indexs, the ratio of pellet in atmospheric pollution is maximum, and fine particle accounts for 70% ~ 80% in pellet.When a large amount of fine particle swims aloft, atmospheric visibility will diminish, and sky seems dusky, and meteorology is called this phenomenon " gray haze sky ".And cause the arch-criminal in this gray haze sky to be exactly fine particle.According to world's Air quality map denotation that US Adm Nati announces, it is that North China of north African and China, east and central China are whole that whole world fine particle pollutes the highest area, most of China area fine particle mean concns, close to 80 micrograms/cubic meter, exceeds 8 times of the relevant contamination index of World Health Organization's regulation.
The harm that topsoil causes the mankind and living environment thereof and impact, gradually by people are familiar with, sum up and get up to have following several aspect:
1. to the harm of HUMAN HEALTH.Human body has been injured three approach, i.e. suck pollution air, surface skin contact stain air and the food eaten containing atmospheric polluting material, except can causing respiratory tract and pulmonary disorder, also can produce harm to cardiovascular systems, liver etc., the life of serious seized people.
2. to the harm of biology.Animal to fall ill containing pollutent food or dead because of suck pollution air or eat, and atmospheric polluting material can make plant disease-resistant power decline, impact is grown, blade face produces blemish or withered death.
3. to the harm of article.As caused chemical lesion to textile clothes, leather, metal products, material of construction, cultural and artistic products etc. and stain infringement.
4. cause acid precipitation, agricultural, forestry, freshwater aquaculture industry etc. are had a negative impact.
5. destroy high-altitude ozonosphere, form Ozone hole, harm is produced to the mankind and biological living environment.
6. global climate is had an impact, as increasing of carbonic acid gas isothermal chamber gas can cause tellurian air to become dim, global weather disaster is caused to increase, and for example the aerosol particles such as flue dust increases, atmospheric turbidity is increased, weaken solar radiation, affect earth long-wave radiation, cause synoptic climate abnormal.
China's topsoil is in recent years day by day serious, although some Conventional pollution obtain certain control, but new pollution is comed one after another, severe contamination is brought to our environment, China's most area fine particle mean concns, close to 80 micrograms/cubic meter, exceeds 8 times of the relevant contamination index of World Health Organization's regulation.For this reason, we should use up the development that oneself maximum effort goes to stop topsoil situation, return our green home.How Air Pollution prevention and control, alleviates harm and the impact of topsoil, constitutes research topic great and urgent now.And adopt buildings to absorb degraded objectionable impurities, be highly effective means.
The well-ventilated of anticollision barrier, and distance car exhaust gas is near, therefore adopt anticollision barrier absorb obnoxious flavour and degrade, the effect that purifies air is very remarkable.
