Description
Technical field
The present invention relates to environmental area, network system and method that particularly a kind of metropolis road gray haze circulation spraying is eliminated.
Background technology
1. the harm of haze weather
Mist or haze are a kind of diastrous weather, and highway, railway, aviation, shipping, electric power system, crop growth etc. are all produced to material impact.Pure water mist itself is less to the health hazard of human body, once but wherein enter toxic gas, or have solid particulate matter, and form gray haze, can cause air quality to decline, influence ecological environment, brings larger harm to health.
What gray haze mainly caused is people's cardiovascular and respiratory disease.Owing to there being the coal-fired difference of heating, North of Huai River resident life expectancy has shortened 5.52.Every cubic metre of increase by 100 micrograms of gray haze concentration, life expectancy is short 3 years, and over nearly 30 years, China's public's smoking rate constantly declines, but lung cancer morbidity rate has risen more than 4 times.This may have certain relation with the increase of gray haze sky.
Gray haze can exert an influence to the respiratory tract of human body, may cause acute upper respiratory infection (flu), acute tracheobronchitis and pneumonia, asthma attack, brings out or increases the weight of chronic bronchitis etc.Particularly child's respiratory tract nose, tracheae, bronchial mucosa are tender, and alveolar negligible amounts, and elastic fibers is grown poor, and interstitial is grown vigorous, is more vulnerable to the infection of Respirovirus.People in the greasy weather, can cause the generation of tracheitis, laryngitis, pneumonia, asthma, rhinitis, eye conjunctivitis and anaphylactia for a long time, to child, teen-age grow and physique all has a certain impact.In addition, foggy weather air quality is poor, and the poor diabetic of resistance very likely occurs that lung and tracheae infect and increase the weight of the state of an illness.
Gray haze sky is also very serious on the impact of human body cardiovascular and cerebrovascular disease, can hinder normal blood circulation, cause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, may bring out angina pectoris, miocardial infarction, heart failure etc., make chronic bronchitis occur cor pulmonale etc.In addition, thick fog weather pressure ratio is lower, and people can produce a kind of sensation of agitation, and blood pressure can increase naturally to some extent.On the one hand often temperature is lower the greasy weather again, and some hypertension, patients with coronary heart disease are indoorly gone to suddenly cold outdoorly from warm, and blood vessel expands with heat and contract with cold, and also can make blood pressure raise, and causes the generation of apoplexy, myocardial infarction.
2. the origin cause of formation of haze weather
Along with the difference of area distribution, the reason that forms haze weather is also different, and in the reason forming at metropolis haze weather, following two key elements are extremely important:
1) meteorological element.There is no obvious Cold Waves Invaded, wind-force is less, and atmosphere is more stable assembles airborne molecule due to not the flowing of air, and swims in air.First be temperature condition, through the survey that haze sky is occurred, while generally generation, temperature interval is many, and at 0 ~ 10 ℃, temperature is below 0 ℃, and airborne steam solidifies, and higher than 10 ℃, atmospheric density reduces, solid particulate matter suspension difficulty.Next is wind condition.When haze weather occurs, wind-force is less, and generally, below 4 grades, wind-force is slightly large, and suspended particulate substance is dispelled very soon.
2) pollutant key element.The aerosol systems of the particle compositions such as airborne dust, sulfuric acid, nitric acid causes the haze that cries of dysopia.Haze is exactly gray haze (mist and clouds in the twilight).Haze weather is a kind of atmosphere pollution state, and haze is the general statement to various suspended particulate substance content overproofs in atmosphere, the particle that especially PM2.5(particle diameter is less than 2.5 microns) " arch-criminal " that be considered to cause haze weather.The source of gray haze is varied, such as vehicle exhaust, industrial discharge, building airborne dust, waste incineration, and even volcanic eruption etc., the normally multiple pollution sources immixture of haze weather forms.The formation existing " source " of gray haze, also has " accomplice ", and Here it is is unfavorable for the meteorological condition of Pollutants Diffusion, once pollutant is gathering for a long time under static meteorological condition, just easily forms haze weather.
3. city traffic is very big to haze weather and air pollution effect
Generally believe that at present city poisonous particles one is external input, the 2nd, the generation in city self, both formation pollution sources that are superimposed.In fact, the first element that haze occurs is that wind-force is little, under such state, the bottom horizontal flow sheet speed of atmosphere is extremely slow, follow the poisonous particles translational speed of Air Flow also very slow, therefore, therefore, haze should be mainly derived from metropolis self, be example take Beijing, according to estimates, the external conveying of the provinces and cities such as Hebei, Tianjin accounts for 20% of Beijing PM2.5 formation, self will account for more than 80%, the accounting of Shanghai and other megapolis may be higher.
Urban inner particulate pollutant is mainly derived from the waste gas of vehicle exhaust, industrial production discharge and the airborne dust of building site and road traffic generation etc., and wherein, traffic tail gas and dust on the roads are again the main pollution sources that haze forms.The haze that traffic causes is mainly two aspects, the one, the discharge of solid particulate matter, the large car that wherein uses diesel oil is " major criminal " of discharge solid particulate matter, comprise the regular bus of large public transport, constituent parts, and large-scale haulage truck etc., because of the adequacy deficiency of burning, tiny carbon granule is discharged in atmosphere.Dust on the roads on the other hand, be example take Beijing, its automobile pollution has reached more than 520 ten thousand for 2013, and this is as being both the large blast fan flowing one by one in city, in its traveling process, the grieshoch on ground is rolled and thrown in the air, and diffusion is towards periphery come gradually, thereby form the contaminated zone with certain altitude and width, from road more close to, ground is lower, and the value of PM2.5 will be larger, pollutes more serious.The road network of megalopolis is very flourishing, 100 near ~ 200m, and not enough 1000m far away, and have a rule road, these road networks link up, and are accompanied by the generation of heavy traffic, by whole city low vacancy pollution.Being enclosed in road central authorities, is tall and big architectural complex, and this weakens the mobility of air, brings difficulty to the dilution of pollutant, has further aggravated the generation of haze disaster.
4. the improvement method of current haze weather
The resolution of state leader in the time talking haze improvement is very large, firmly as poverty is declared a war declares a war to pollution.Nearly stage haze weather expanded range is the red light that the Nature lights to extensive development pattern.In the time administering, emphasize to strengthen ecological environmental protection, make a decision to complete indispensable and demanding task with hard measure, meanwhile, attach most importance in the megalopolis and the region that take place frequently with haze, administer as breach take PM2.5 and PM10.Present stage, haze improvement was generally by following several respects approach:
The one, government improves law.External control atmosphere pollution legislate go ahead, has now formed complete legal system.At present, China's air pollution legislation is not perfect, should improve as early as possible relevant laws and regulations, has implemented the Air Pollution Prevention Law of 13 years and has urgently revised, the Legal System that PM2.5 controls.Control content as increased zone defence connection in Law on Environmental Protection Laws & Regulations, strengthen motor-vehicle tail-gas management, revise automotive emission standard etc. by legislation.
The 2nd, economic restructuring.China is that fossil energy accounts for Chinese overall energy resource structure 92.7% take coal as main energy consumption structure.In the face of environment pollution is serious, the severe situation of ecosystem degradation, the traditional development model take fossil resource as cost is hard to carry on, needs badly by " high-carbon " economical to " low-carbon (LC) " economic transition.And avoid the fundamental policy of pollution that caused by coal burning, and to use exactly clean energy resource, reduce disposal of pollutants from source.
The 3rd, industry energy conservation reduces discharging.According to the principle of " those who created pollution to clearing it up ", to ' force ' exactly enterprise transformation upgrading.Enterprise will advance cleaner production, changes the mode of production by scientific and technological input, uses the clean energy resourcies such as natural gas, solar energy, reduces the discharge of dusty gas, reduces automobile trip, and then realizes energy-saving and emission-reduction.
Present stage, still has by unmanned aerial vehicle, disperse fog and fall the trial of haze aspect, but its cost is high, and the scope of implementing operation is little, and the time is short.
The above governance way of comprehensive analysis, is generally to be undertaken by approach such as management, law, limit rows, and has obtained certain effect, but very limited, when weather conditions possess, haze sky is attacked in the same old way.In fact, the improvement of haze weather, particularly gray haze is international headache, and present stage there is no particularly preferred improvement method in the world, need to be broken through technically.
Summary of the invention
The object of the invention is is not affecting under the prerequisite of the magnitude of traffic flow, and a kind of elimination network system and method for the city gray haze pollution sources that cause because of garage's traffic or other pollution sources is provided, and realizes air purification.
Elimination network system and the method for a kind of urban road gray haze pollution sources that the present invention proposes, the main contents of its invention comprise following four main aspects: (1) urban road gray haze concentration affects factor and PM value real-time detecting system.Mainly the important parameters such as temperature, wind-force, vehicle density, PM concentration value being detected in real time, is definite foundation that provides of spray parameters.(2) the device network system that gray haze spraying is eliminated, mainly carries out production and the conveying of heavy pressure fine spray, comprises water booster pump, water smoke main line, water smoke branch road, nozzle, power supply and water source etc.(3) spraying decision control system.According to the correlated variables parameter detecting in real time, carry out in control centre on the basis of statistical analysis, flow, frequency, pressure and the duration etc. that form spraying operation are controlled parameter, and drive implement system.(4) water spray detection, control and the device systems of zones of different are organically combined, and have formed accurately gray haze elimination network system and the method for the controlled fixed spraying in high-altitude of the present invention.
For inventive point (1) ~ (4), the principle of its realization is mainly as follows: in vehicle traveling process, the tail gas of ejection, wrapping up in and failing clean-burning tiny carbon granule, and contain the poisonous sulfide gas of part, oxides of nitrogen gas and dust on the roads etc., throw to high-altitude, and gradually upwards and periphery diffusion, form contaminated zone; The contaminated zone of different roads overlaps on together, thereby by the low vacancy pollution in whole city.The present invention utilizes the mode of spraying to eliminate gray haze, and increasing the weight of gray haze with the greasy weather has essential difference.The spraying facility of installation and road top, the particle diameter of the atomized water of its ejection is much larger than the particle diameter of natural fog, and weight is large, can not be suspended in the air, thereby can drop to very soon ground, in its landing process, meet with the tail gas and the airborne dust that rise, and the latter is wrapped and together drop down onto ground.After spraying a period of time, the gray haze concentration of road top is reduced very soon, now, stops spraying.Along with the evaporation of ground moisture, and motor vehicle exhaust emission, the PM concentration value of road top progressively rises again, while reaching finite concentration, then carry out spraying operation, so circulation, can avoid roadway pollution to spread to all near spaces, thereby eliminate the gray haze that road traffic produces.
Preferably, network system and method that the road gray haze circulation spraying of described metropolis is eliminated, its spraying water main should be embedded in underground, in reducing ground space resource, is convenient to cold-proof freeze proofly, and spraying arm has been fit to do anti-freezing and heat-insulating processing;
Preferably, network system and method that described metropolis road gray haze circulation spraying is eliminated, its atomization pumping plant should arrange reservoir or the storage tank of a constant volume.
Preferably, network system and method that described metropolis road gray haze circulation spraying is eliminated, its nozzle should arrange enough height, and water spray is higher, and the region of controlling pollution sources is larger.
The invention has the beneficial effects as follows:
1, do not affect traffic.Orthodox car sprinkler pipe is supported and is occupied a fast traffic lane, and running speed is slow, large on the normal current impact of vehicle.Adopt the high-altitude spraying operation of fixing pipeline to have no effect to traffic;
2, the dedusting haze speed that disappears is fast, effective, can replace the operation of automobile watering and lowering dust.Traditional automobile watering operation only can prevent kicking up of floor-dust, cannot remove automobile exhaust pollution thing; And adopt high-altitude spray for dust suppression to fall haze, and can remove tail gas and dust from land surface, and haze dedusting operation falls in entire road All Ranges simultaneously simultaneously, in the several seconds, can complete the haze operation process that once disappears of all roads in city, speed is fast.
3, can realize the accurate control to gray haze pollution sources.Only, with regard to dust on the roads control, tradition watering dedusting is carried out by rule of thumb, and is limited to the foster personnel's of pipe sense of responsibility, often can not get effective control, and a most of the time road is all in dry state.Present networks system can detect in real time, and can computer aid decision-making system, according to vehicle density, temperature, wind-force, pollutant levels etc., adjusts in real time spray parameters, realizes accurately controlling in real time pollution sources.
4, operation cost is low.The manually actual field operation of whole spray process, water, the electricity charge that only must be a small amount of, if charges for water and electricity by 1 yuan/ton, degree, the expense of road every day of wide 1 kilometer of 50m is in 200 yuan, cost is extremely low.
5, reduce urban heat land effect.If this screen system can be installed, in hot summer, it still has the function for urban cooling.In summer, the ability of the road surface heat absorption of black is strong especially, road surface temperature under solar radiation raises rapidly, reach degree more than 70, and periphery meadow greening regional temperature rising amplitude is generally in 10 degree, make the heat discharging after the radianting capacity of road surface to atmosphere and cooling thereof will be much higher than afforested areas, approach more than 10 times, be the main thermal source of Summer urban heat island effect, the atmospheric temperature in city will be spent higher than Huo Zhoujin rural area, suburb 2 ~ 5.After haze screen is installed, in summer spray process, can greatly reduce pavement temperature, reducing city temperature, when alleviating heat island effect, delay ageing of asphalt, improve the application life of flexible pavement.
The specific embodiment
Along with the expansion of city size and the increase of city automobile recoverable amount, vehicle, bringing people's trip simultaneously easily, gives the pollution in city also more and more serious, adds the pollutions such as other industry, fire coal, once weather conditions possess, low latitude, whole city firmly by gray haze pin.How removing fast the gray haze causing because of garage's traffic, purifying city air, is international headache, is also problem in the urgent need to address.
The present invention utilizes can the disappear principle of haze dedusting of artificial spraying, by Test and control, propose on the road of a kind of metropolis, on the intensive arterial road and through street of special traffic flow, the haze cleaner that disappears of spraying is installed, all installations and facilities connect together, and arrange with whole city road network is parallel, have formed the urban road of the present invention haze dedusting network system that disappears.This system is made up of detection system, device network system, decision control system three parts, and detected parameters, after machine analyzing and processing, forms spraying and controls parameter as calculated to control centre through Internet Transmission, controls whole device systems.
For metropolitan gray haze pollution sources are effectively controlled, can adopt the mode of total score control, setting up on the basis of city-level control centre, Dui Ge district sets up subregion control station, the gas and water pump of the thin water atomization pumping plant of installation high-voltage in subregion central control station, and detection, computational analysis and control appliance system, and produce heavy pressure fine spray by control system driving arrangement, the nozzle by Pipeline transport to road top.Typical metropolis road gray haze is eliminated network system general structure design as shown in Figure 1.
(1) structure of device network system
1. high-pressure fine water atomization pumping plant is built
For forming high-pressure atomization water, must build at a certain distance a thin water atomization pumping plant of minitype high voltage.In Design of Pump Station, should consider that the design of site selection for pumping station, reservoir, pumping plant are antifreeze as a whole, the factor of the aspect such as the selection of power and water source demand and pump.
The addressing of pumping plant.Should select the intersection of arterial road, through street, like this, single pumping plant service section will be longer.Usually, through suitable relaying supercharging, single pumping plant at least can be served the section of diameter 4 kilometer range.Meanwhile, site selection for pumping station should consider to be convenient to the access of municipal water sources and power supply.
The design of reservoir.First the volume of reservoir should guarantee to be full of whole pipe-line system, at least can meet the water supply volume of operation in 1 to 2 hour simultaneously.Suppose each pumping plant service 8km section, hour water in every kilometer of section is about 10 m
3, pumping plant storage capacity should be at 80 ~ 160 m
3.Specifically to determine according to parametric synthesis such as the design of pipeline, laying mode, Sprayable and link length.
The selection of water pump.Water pump lift and flow are to control emphasis, apply morely in the designs such as water-supply systems, fire fighting system water supply, and technology is comparatively ripe, select with apply can be with reference to corresponding standard.
Water source power supply supply.The municipal network of rivers and the electrical network in access city.
Pumping plant is antifreeze.Be haze weather season occurred frequently winter, and reply pumping plant is carried out heater by service, the icing blocking pipeline of control.
For further strengthening the haze dust removing effects that disappears, pumping plant construction can consider to be equipped with pneumatic plant facility system, to form aerosol dust removal system.System only increases air pump and corresponding pressure-regulating device, and atomizing effect is good like this, and its particle water diameter is 1 ~ 10 μ m, is only 1/10 of water mist dust-removing particle, is more easily combined with dust molecule, reaches the object of the haze dedusting that disappears.Meanwhile, its water-saving performance is good, and aerosol dedusting is by abundant moisture atomization, and injection flow rate is only 1/8 of water mist dust-removing.Accompanying drawing 2 is a kind of typical aerosol cleaner systematic schematic diagrams, wherein 1 to 12 be respectively reservoir, overflow valve, high-pressure hydraulic pump, high-pressure pump, air gauge, flowmeter, water pressure gauge, water under high pressure pipeline, high pressure gas pipeline, high pressure refinement mist main line, high pressure refinement mist branch road and nozzle etc., wherein, 1 ~ 9 is laid in Regional Control Center, and 10 ~ 12 is section atomizer passgae network system.
2. atomizer passgae is selected and is laid
Spraying main will bear larger water pressure, should adopt seamless steel pipe welding, and its caliber is determined according to flow, but must not be less than 100mm.Main conduit and road are parallel to be arranged, should be laid in undergroundly, adopts the mode of burying underground, can play so good antifreeze effect.
The general caliber of spraying arm is less, can select the following coating steel pipe of DN50, and carry out the antirust processing of mopping, also can select high-pressure hose.Arm generally can adopt welding manner to be connected with main, or other special joint.For the arm that goes out ground, its load is very little, can pass through anchor ear, is fixed together, to reduce construction costs with light pole.Arm also can be fixed by special vertical rod.Should there be enough distances on vertical arm and ground, more than being preferably in 10m, can control so wider pollution sources.The density that its arm is arranged is relevant with pressure, the width of road etc. of atomized water, it is design considerations that Ying Yineng controls whole Road width, there is different arrangements according to different Road widths, road structure form, can select single as 20m is following, the following employing of 40m is double, the following mode that can adopt 3 rows or arranged in rows of 70m.Accompanying drawing 3 is layout profiles of a kind of typical road atomizer passgae, and in figure, 1 ~ 5 is respectively high-pressure water mist main line, high-pressure water mist arm, fixing anchor ear, fixing vertical rod, nozzle etc.Main adopts pre-buried mode, and arm adopts built on stilts mode.
3. nozzle selection and installation
At present, the kind of nozzle is many, and alternative scope is wide, should select anti-aging, cold-resistant, sun-proof, acid and alkali-resistance, the product of long tongue not.Its installation will become with level certain upwards vibrating deflection (being generally 45o left and right), to increase the control range of single-nozzle as far as possible.
(2) detection system construction
Detection system mainly affects parameter with regard to gray haze and equipment operation control parameter detects.
Affect parameter and comprise that wind-force, outside atmosphere temperature, vehicle density and PM concentration value etc. detect in real time.First be wind-force, the size of wind-force directly affects the diffusivity of near-earth air gray haze, and wind-force is larger, spreads sooner, and on the contrary, wind-force is less, and gray haze is more serious to subaerial pollution, and general wind-force is less than 3 grades, and city the probability that gray haze pollutes occurs and rises suddenly; Secondly, temperature is another Important Parameters, and temperature very easily causes gray haze sky between 0 ~ 10 ℃, and temperature is lower than 0 ℃, and the steam in atmosphere is solidified, and higher than 10 ℃, vertically increases to atmosphere exchange velocity, is also difficult for closely in surface air, assembling.Vehicle density is another important factor in order, and in Vehicle Driving Cycle process, its tail gas and the airborne dust causing are one of pollution sources of gray haze sky, metropolis maximum, and driving vehicle is more, and gray haze concentration is larger, must detect in real time it.PM value is the integrated value of gray haze concentration, has directly reacted the degree of contamination of ground air, tackles it and strengthens detecting.For wind-force, outside atmosphere temperature etc., can lay voluntarily corresponding device systems to detect, also can, by networking with meteorological department, obtain real-time related data resource.For vehicle density, the vehicle density detection system that can lay by road below, will detect that transfer of data arrives control analysis center, if there is the real-time detected value of the flow of corresponding road in vehicle supervision department, also can be transmitted through the network to control centre.PM concentration detects and can, in a certain amount of test station of road laying along the line, obtain in time corresponding data.
Equipment operation is controlled parameter and is mainly comprised water under high pressure pressure, high-pressure gas pressure, piping flow etc.These parameters are directly controlled control range, the spraying operation amount etc. of spraying operation, can directly obtain relevant parameter by corresponding head flowmeter and sensor.
(3) decision control system
The Real-Time Parameter obtaining by detection system, as data values such as wind-force, temperature, vehicle densities, enter statistical analysis system, at the scene on the basis of test, with some parameters of spray amount, as spray time interval, mist flow, pressure etc. carry out real-time coupling calculating, to seek optimum spraying operation parameter, and according to the variation of road environment condition, adjusted in real time.
For the driving of device systems, can pass through mode manually, set and started, also can be by the programmable controller being connected with computer, drive corresponding water pump, air pressure pump and valve opening state along the line.
Data terminal, analysis and Control system and the main water of detection system, atmospheric pressure pump can be built in a place, form pump house control branch center, the road within the scope of control area and the diffusion of the gray haze of other major polluting sources.Network system can be passed through in branch center, citywide, connects together, and forms city-level gray haze control centre, is polluted by city-level center United Dispatching, control citywide gray haze.
Disappear in haze dedusting operation in concrete spraying, according to meteorological condition, vehicle density etc., can adopt following several spraying operation mode: cycle operation, simultaneously operation, timing operation and manually control the various ways such as operation.Cycle operation refers to that each nozzle is according to the timing automatic work of setting program a period of time, and the time is adjustable; Simultaneously operation refers to that all nozzles in the whole city work simultaneously; Timing operation refers to the work that automatically starts and stop nozzle according to the predefined time of program; Manual working refers to the mode of manual start and stop nozzle operation.Because metropolitan scope is wider, spatial extent is large, the general mode of automatically controlling that adopts.
For concrete spraying operation control,, according to detected parameters spraying operation is adjusted automatically by analysis and Control system.Such as for vehicle density less night, meanwhile, temperature is lower, and evaporation from land speed is relatively slow, the duration of a spraying operation can be shortened, and the time interval of spraying operation lengthen, to save the consumption of hydroelectric resources; And for evening peak traffic period morning, system will shorten the time interval of spraying operation automatically, strengthen each spray amount.
(4) antifreeze processing
In low temperature sky, in the time that atmospheric temperature approaches 0 ℃, stop spraying, or increase appropriate nontoxic antifreezing agent and carry out spraying operation.If stop spraying, can be back to by system in the reservoir at pump house center the high-pressure atomization water in pipeline, also can, by closing high-pressure hydraulic pump, by high-pressure pump operation, the atomized water in pipeline be blown off.
