Description

Device and system for reducing PM2.5 pollution of regional ambient air

Technical Field

The utility model relates to an environmental protection technical field, in particular to reduce regional ambient air PM2.5 and pollute device and system

Background

At present, the atmospheric pollution condition of China is still very serious, and the concentration of total suspended particles in the urban atmospheric environment generally exceeds the standard.

Scientific and technical journal information of 17 th 4 th 2019, and a report of 2019 global air condition (based on 2017 data) issued by the American health effect institute show that the number of people who die from stroke, heart disease, lung cancer, diabetes and chronic lung disease due to long-term exposure to outdoor and indoor air pollution in the world in 2017 reaches nearly 500 ten thousand; 120 thousands in china. The report indicates that among all health risk factors worldwide, the air pollution level ranks fifth, ranking after dietary risk, hypertension, smoking and high fasting glucose. In china, air pollution is the fourth of the health risk factors, and more people die of air pollution related diseases than of traffic accidents or malaria every year after dietary risk, hypertension and smoking.

The 2019 global air condition report first included an assessment of air pollution affecting people's life expectancy. The data show that 2017, globally, the life expectancy of both outdoor and indoor air pollution is shortened by 20 months, which means that the life expectancy of infants born today can be increased by 20 months if the air pollution can be eliminated.

It is estimated that air pollution shortens the life expectancy of the human population by 23 months in 2017 in china, wherein outdoor and indoor air pollution respectively reduces the life expectancy of the human population by 15 months and 8 months. In non-infectious diseases, the contribution rate of air pollution to lung cancer incidence is 26%, and the contribution rates to heart disease and stroke are 17% and 12%, respectively.

The world health organization estimates that air pollution is responsible for approximately 200 million worldwide early deaths each year. This effect is mostly borne by people in developing countries. In many cities, the annual average value of inhalable particles is over 70 micrograms per cubic meter. In 2005, the air quality standards promulgated by the world health organization suggested that these values should be below 20 micrograms per cubic meter in order to prevent health damage.

The southern China, academy of China, considers that the value of PM2.5 is very important and is worthy of attention. "as a physician i know, the accessible lung particles can directly enter the alveoli, so the effect is even greater. "after a special visit of 204 cities in 2006 in the United states, the number of people with heart failure is increased by 10 mg per cubic meter of PM2.5, research is also carried out in 2005 in hong Kong, the hospital admission rate of acute diseases is increased by 1.94% and the hospital admission rate of chronic obstructive lung is increased by 3.1% by 10 mg per cubic meter of PM2.5, and research also shows that the number of outpatients of patients is increased by 10% -15% in a haze weather. "

The particles which can naturally settle in the inhalable particle air are called dust fall (the particles are larger than 10 microns), the particles which are suspended in the air and have the particle size of less than or equal to 100 microns are called Total Suspended Particles (TSP), the sources are mainly factory waste gas, automobile tail gas, building flying dust and the like, wherein the particles which have the particle size of less than 10 microns are called inhalable particles, the particles which have the particle size of less than 2.5 microns are light and can float in the atmosphere for a long time, the floating range is from several kilometers to tens of kilometers, and the particles are continuously accumulated in the atmosphere, so that the pollution degree is increased. In recent years, it has further been recognized that particles having a particle size of 2.5 microns or less (PM2.5) suspended in air tend to be enriched in toxic heavy metals, acidic oxides, organic pollutants, bacteria, viruses, etc. of air, and have a far greater impact on human health than particles having a particle size of 2.5 to 10 microns. An adult breathes an average of 15 cubic meters of air per day, and it is not certain that people breathe heavily polluted air, which is harmful to health.

In recent years, it has further been recognized that particles having a particle size of 2.5 microns or less (PM2.5) suspended in air tend to be enriched in toxic heavy metals, acidic oxides, organic pollutants, bacteria, viruses, etc. of air, and have a far greater impact on human health than particles having a particle size of 2.5 to 10 microns. The particles with the particle size of more than 10 microns can be occluded by vibrissa and can be discharged out of a human body through cough, the particles with the particle size of less than 10 microns can deposit in a lung along with the breathing of a human body, and even can enter alveolar blood (3 hundred million alveoli are formed in the deep part of the lung of the human body), and the particles are deposited on the alveoli to damage the alveoli and mucosa, so that chronic fibrosis of lung tissues is caused, pulmonary heart disease is caused, asthma is aggravated, chronic nasopharyngitis, chronic bronchitis and other diseases are caused, and the life can be seriously threatened. The harm of the particles to children and old people is particularly obvious. The inhalable particles also have strong adsorption capacity, are carriers and catalysts of various pollutants, can be sometimes aggregates of various inhalable particles, and are the chief culprit of various diseases.

PM2.5 was listed as an important standard for air quality detection in the united states as early as 1997.

The investigation results published in 2007 of environmental province of Japan show that if the concentration of airborne particles increases by 10 micrograms per cubic meter, respiratory diseases of some of the elderly over 65 years will become worse within 5 days thereafter, and the death rate of people of this age group due to asthma or pneumonia will increase by 1.1%. The PM2.5 particles can penetrate through the defense hair-like structures of the respiratory tract of the human body (namely nasal cilia in the nasal cavity) and enter the human body, and diseases in the whole range of the human body are caused. PM2.5 may also produce toxic effects on the cardiovascular system. It harms the cardiovascular system of the human body mainly through two ways: by causing inflammatory reactions and secondary hypercoagulative states, and by altering autonomic nervous function. After a human body inhales PM2.5 particulate matters, a series of acute stress reactions of the body can be caused, and the functions of a circulatory system are changed, so that cardiovascular system diseases are caused. In addition, PM2.5 can induce the onset of acute myocardial infarction in the short term. 50% of inhaled PM2.5 can be deposited in the lungs, causing pulmonary sclerosis, asthma, and chronic bronchitis.

U.S. studies have found that the concentration of particulate matter in the air of a large city, which is less than 10 microns in diameter, is typically 4-20 micrograms per cubic meter, and that for every 10 micrograms per cubic meter increase in concentration, the risk of cardiovascular disease increases by 24% and the risk of death increases by 76%. The Swiss research shows that the closer a residence is to a highway, the more easily people suffer from respiratory diseases, and the disease risk is reduced by 12 percent for every 100 meters of residence to the highway. German studies have found that the incidence of coronary heart disease increases by 1.85 times compared to residents living within 150 meters of the traffic key.

The number of patients who breathe in the institute on dust-haze days is increased by more than 15% in the southern mountains of the academy of China, and the fact that the particle size in dust-haze is less than PM5 has a great influence on human bodies is pointed out. The report of the sustainable future of the marching environment, namely the national environmental analysis of the people's republic of China, which is jointly completed by a working group consisting of environmental experts at home and abroad and a professional team of an Asian development bank, is released in 2013 in 14 days 1 month, and the report shows that only less than 1 percent of 500 biggest cities in China meet the air quality standard recommended by the world health organization. The economic loss caused by air pollution in China every year is equivalent to 1.2 percent of the total value of domestic production based on the estimation of disease cost, and is up to 3.8 percent based on the estimation of willingness to pay.

The economic loss caused by air pollution in China every year is estimated to be 1.2 percent of GDP by disease cost, is estimated to be up to 3.8 percent of GDP by willingness to pay, and is respectively 5658 million yuan and 17919 million yuan by 471564 million yuan of GDP in China in 2011.

In order to deal with PM2.5 pollution and ensure the health of citizens, PM2.5 spraying vehicles similar to watering lorries are popularized in various parts of China, PM2.5 in the ambient air nearby the spraying vehicles is accumulated and settled on the ground by spraying the spraying vehicles into the air on various roads in the city, the aim of air freshening is achieved, the same principle as the clear air freshening after rain is achieved, and the good effect is achieved within a certain distance range, but the following defects still exist.

(1) The range of fresh air is limited.

Although a high-power sprayer is adopted in the PM2.5 spraying vehicle, the spraying height is twenty meters or more (below the height of ten floors), and the width is twenty meters or more (if the spraying vehicle is influenced by trees beside a road, the width is smaller). I.e. the range of fresh air (cross-section of 30 m by 30 m), is not useful at distances above 100 m from the PM2.5 spray vehicle.

(2) The period of time for freshening air is limited.

A PM2.5 spraying vehicle runs along an urban road to perform air freshening operation, and the air quality along the road is improved. And PM2.5 pollution in the ambient air of the road section where no PM2.5 spray vehicle runs is still serious.

A large city may have hundreds of roads, and the time period for the PM2.5 spray vehicle to pass is limited. If a road has four spraying vehicles passing by the road a day, the effective time period of one time is half an hour, and the total time is two hours. That is, with this approach, only two hours of air PM2.5 pollution out of 24 hours a day is air-fresh.

(3) The efficiency is low.

The fresh air action range of a PM2.5 spray vehicle is twenty meters high and twenty meters wide, the water mist is maintained in the air for ten minutes, the total time from the beginning of spraying to the completion of the settlement of the water mist is twenty minutes from the time of fresh to the time of recontamination, and the effective time period is half an hour. About 5 tons of running water are loaded in a PM2.5 spraying vehicle, water is required to be filled in a place with a special tap after spraying (certain time is required for filling water), and the vehicle returns to the original road section to continue fresh air operation (certain time is required for returning to the original road section), so that the efficiency is low.

(4) The investment and operation costs are high.

A large city has hundreds of roads, at least hundreds of PM2.5 spraying vehicles, automobile purchase, vehicle maintenance, maintenance cost, gasoline cost, driver and manager wages are required to be put in, and the input and operation cost is not low.

(5) Affecting traffic.

In order to effectively perform air refreshing operation and ensure that the PM2.5 in the atmosphere is completely settled, the PM2.5 spraying vehicle is not suitable for fast running. The PM2.5 spraying vehicle running slowly is easy to cause traffic jam, and frost is added on snow during rush hours.

(6) The resource utilization is not reasonable.

In a time period when the PM2.5 in the atmosphere is seriously polluted, although nearly hundreds of PM2.5 spraying vehicles are all moved to perform air refreshing operation, the effect is not satisfactory due to the limited air refreshing range and the limited air refreshing time period. Under weather conditions such as raining, blowing strong wind, atmosphere PM2.5 pollutes not seriously or pollution-free period, and PM2.5 spraying vehicle just need not to go out to move, causes equipment idle, personnel extravagant.
