Description
Technical field
The invention belongs to normal lighting technical field, particularly one purification degraded pernicious gas road lamp frame and processing method thereof.
Background technology
China's atmospheric pollution level is serious all the more, and due in China's environmental improvement, only the Market Orientation administered of water pollutions and solid waste is higher, all the other are if air contaminant treatment is owing to being subject to weather effect and can shifting between different geographical, therefore all the time, the enthusiasm of government to air contaminant treatment is lower, and this part market is also comparatively weak.
The loss that Chinese city air 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 particle.Ministry of Health of China has assert that the breathing problem 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 volcano eruption, forest 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.Because man-made pollution source is common and exist frequently, paid close attention to so carry out more people compared with natural pollution source.Air primary pollution source has:
⑴Gong industrial enterprise is the main source of atmosphere pollution, is also one of emphasis of atmospheric hygiene protected working.Along with developing rapidly of industry, kind and the quantity of atmosphere pollution are increasing.Due to character, scale, activities, the difference such as raw material and product category of industrial enterprise, they are also different to the degree of atmosphere pollution.
(2) life cooking stove and heating boiler are in residential community, 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 significant is the waste gas that automobile is discharged.The feature of auto-pollution air is that the pollutant of discharging is very near apart from the breathing zone of people, can directly be sucked by people.Main containing carbon monoxide, nitrogen oxide, hydro carbons (hydrocarbon), 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 pollutants indexs: pellet, nitrogen dioxide and sulfur dioxide.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 particle of 10 microns, but do not comprise " individual first watch is little ", the particle that is less than 2 .5 microns (being called for short " fine particle ", also known as PM2.5).In above-mentioned three contamination indexs, the ratio of pellet in air 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 concentration, close to 80 micrograms/cubic meter, exceeds 8 times of the relevant contamination index of World Health Organization's regulation.
The harm that atmosphere pollution 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 health.Human body has been injured three approach, i.e. suck pollution air, surface skin contact stain air and the food eaten containing atmosphere pollution, except can causing respiratory tract and PUD D, also can produce harm to cardiovascular system, liver etc., the life of serious seized people.
2. to the harm of biology.Animal to fall ill containing pollutant food or dead because of suck pollution air or eat, and atmosphere pollution can make plant disease-resistant power decline, impact is grown, blade face produces blemish or withered death.
3. to the harm of article.As to textile clothes, leather, metal product, constructional materials, cultural and artistic products etc., cause chemical lesion and stain infringement.
4. cause acid precipitation, agricultural, forestry, freshwater aquaculture industry etc. are had a negative impact.
5. destroy high-altitude ozone layer, form Ozone hole, harm is produced to the mankind and biological living environment.
6. global climate is had an impact, as increasing of carbon dioxide isothermal chamber gas can cause earth atmosphere increasing dim, global weather disaster is caused to increase, and for example the particulate such as flue dust increases, atmospheric turbidity is increased, weaken solar radiation, affect earth long-wave radiation, synoptic climate may be caused abnormal.
China's atmosphere pollution is in recent years day by day serious, although some Conventional pollution obtain certain control, but new pollution is comed one after another, serious pollution is brought to our environment, for this reason, we should use up the development that oneself maximum effort goes to stop atmosphere pollution situation, return our green home.How Air Pollution prevention and control, alleviates harm and the impact of atmosphere pollution, constitutes research topic great and urgent now.And adopt purification degraded pernicious gas street lamp to absorb degraded hazardous substances, be highly effective means.
At present, existing street lamp device price is higher and easily produce corrosion along with the increase street lamp tube-surface of service time, has a strong impact on the attractive in appearance of street lamp.Existing street lamp device originally can produce certain pollution to air when production and processing in addition, the most important thing is that existing street lamp device does not possess the ability of absorption degradation pernicious gas, for purification degraded air in and near urban road vehicle produce a large amount of pernicious gases helpless.
