Description
Technical field
The present invention relates to atmospheric environments to administer field more particularly to a kind of atmospheric haze low latitude control techniques.
Background technology
Haze, also referred to as gray haze refer to the aggregate of a large amount of small dusts, soot or salt grain in an atmosphere of suspending, keep air muddy
Turbid, horizontal visibility is as low as a kind of 10 kilometers of weather phenomena below.Its steam is unsaturated, generally in yellow and orange grey, day
Interior variation unobvious.Since gray haze process is influenced significantly by anthropogenic discharge's source gas sol particles, and influenced by steam in one day
And occur mutually conversion, therefore meteorological department usually will " haze " be incorporated to " mist " together as diastrous weather phenomenon progress early warning it is pre-
Report, is referred to as " haze weather ".
Sulfate is the maximum contribution person of haze, and household forms sulphur using coal-fired and coal fire discharged power plant sulfur dioxide
Sour particle.Coal-fired another byproduct nitrogen oxides is initially occurred in the form of natural fog, has also pushed the formation of haze, natural fog
In comprising size be some tens of pm larger particles, these droplets evaporation after will be formed covering whole city small acidity haze grain
Son, to produce haze.
PM2.5 refers to the fine particle that kinetic diameter is less than or equal to 2.5 microns in air, also referred to as particulate matter
Object, the contaminant particles such as sulfate therein, nitrate, organic matter are the main reason for causing haze weather.Therefore, present mist
Haze weather mostly links together with PM2.5 concentration over-standards.
Haze and PM2.5 are the indexs for characterizing air pollution, mainly related with anthropogenic discharge's atmosphere pollution, to human body
Health has negative effect.The formation of haze and PM2.5 are closely related, and control PM2.5 can mitigate haze.
In recent years, China big city haze day frequency of occurrences showed increased.In especially 2013 beginning, China central and east goes out
Existing 4 wide range of haze weather, more than 140 ten thousand square kilometres, 800,000,000 or more populations be affected, Beijing's haze weather in January is up to
26 days, cause all circles' extensive concern.
Atmospheric haze control measures, which have, at present increases the supervision of disposal of pollutants enterprise, reaches discharge standard, or even shut down dirt
The measures such as dye discharge enterprise, watering and lowering dust, but all haze problem cannot be solved from basic, and bring prodigious economic loss.
So the measure still without preferably administering atmospheric haze.
Invention content
Technical problem to be solved by the invention is to provide a kind of atmospheric hazes to prevent comprehensive technology system, is sprayed from low latitude
Safety-type haze prevents material, quickly eliminates haze, and reduce haze influences caused by communications and transportation.
The present invention is to solve above-mentioned technical problem and the technical solution adopted is that provide a kind of atmospheric haze low latitude prevention skill
Road is divided into a grid, such as by art system per 5-10 kilometers：City inside road, provincial highway, national highway, highway, iron
Road, airfield runway etc..Platform is administered by setting up atmospheric environment comprehensive along both sides of the road, 0.5-5 meters of height is spaced 50-100
Rice sprays safety-type atmospheric haze prevention material, and low latitude is quickly administered, to eliminate influence of the haze to communications and transportation.
Above-mentioned atmospheric haze low latitude control techniques, wherein：Each grid is mainly by pre-alarming system, joint control system, anti-
Model system administers system, prevention platform, prevention equipment, takes precautions against material and administer material composition.
Above-mentioned atmospheric haze low latitude control techniques, wherein pre-alarming system passes through dirty in air in real-time monitoring grid
Dye gas composition and concentration, data processing provide alert, and transfer data to prevention platform, and specific aim opens prevention system
Or system is administered, material or improvement material are taken precautions against by preventing equipment application, joint control system cooperates with work between starting grid when necessary
Make.
Above-mentioned atmospheric haze low latitude control techniques, wherein atmospheric environment comprehensive administers platform and is mainly disposed to road
Both sides spray safety-type haze from 0.5-5 meters of low latitudes and prevent material, quickly eliminate haze, improve road visibility.
The present invention, which compares the prior art, following advantageous effect：Atmospheric haze low latitude Prevention Technique body provided by the invention
System is a kind of haze control method of quick raising road visibility, be at all on road, it is small-scale by road k-path partition
For grid, each grid setting atmospheric environment comprehensive administers platform, how many pollutant emission is put into anti-according to pollutants calculation
Model and improvement total amount of material.And each system cooperates, and synergistic effect, according to haze detection data on road, low latitude is quick
Safety-type haze prevention material is sprayed, influence of the haze to communications and transportation is eliminated in the action that can be got instant result.
Description of the drawings
Fig. 1 is that road atmospheric haze of the present invention low latitude prevention regional network is formatted schematic diagram；
Fig. 2 is that atmospheric haze low latitude prevents schematic diagram.
1. road；2. atmospheric environment comprehensive administers platform；3. grid；4. spray material；5. pollutant.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples.
The atmospheric haze low latitude control techniques road network of the present invention is formatted schematic diagram such as Fig. 1, first divides road 1
At grid 3,5-10 kilometers one, one section one section, such as：Urban road, provincial highway, national highway, highway, railway, airfield runway.Needle
Haze prevention is subject to respectively to each grid.
Specific control method is to build several atmospheric environment comprehensives in each grid 3 and administer platform 2, be highly 0.5-5
Rice, spacing are 50-100 meters, and sprinkling atmospheric haze prevents material 4, and haze 5 is eliminated in grid, will not cause to hand on a large scale
It is logical to influence.
Atmospheric haze low latitude control techniques specific workflow：Early warning system first, by analyzing atmosphere pollution
Composition and concentration obtain possibility or atmospheric haze pollution level that atmospheric haze occurs, start early warning system, according to dirt
Dye degree judges whether to need grid joint control, if necessary to start joint control system, transmits data to prevention and control platform, if
Do not need grid joint control, then directly send data to prevention and control platform, carry out data processing, judgement be start crime prevention system or
Governing system.If haze is not yet formed, only pollutant concentration, such as sulfur dioxide, nitrogen oxides, ammonia, VOCs exceed
A certain range has in the presence of the risk for causing haze and being formed, then starts crime prevention system, material type is taken precautions against in selection, is calculated and is taken precautions against
Material utilization amount sends out instruction to prevention equipment, and spraying operation takes precautions against material；If haze has been formed, start governing system,
According to the composition and concentration of haze, such as sulfate, nitrate, dust, VOCs, material type is administered in selection, is calculated and is administered material
Expect dosage, and instruction is sent out to prevention equipment, spraying operation administers material, and the atmosphere data detection after prevention feeds back to early warning
System judges to operate in next step.
