Description
Technical field
Weather monitoring device technical field is the utility model is related to, specifically a kind of inverted pyramid formula air dewfall hydromining
Acquisition means.
Background technology
The dew of nature is divided into two classes, and one kind is the reallocation water or soil of soil-plant-Atmosphere System Water Cycle
Earth distills, and another kind be air dewfall water, be by air contained steam it is supersaturated partly to the cold on ground or atural object surface
Upper condensation forms, and temperature is reduced to below dew point by the influence of Surface long wave radiation, and the scope that generally cools does not surpass
Cross 10 DEG C.Relative humidity in air(RH)It is sufficiently high(General RH>70%), while bright day gas and weak wind are air
The necessary condition that dewfall water is formed.
It is inherently distilled water to air dewfall water, therefore under no external influence, dew be free from yin, yang from
Son, metal ion and bacterium, unless dew absorbs the gas in dissolving ambient atmosphere in forming process or captured by substrate
The aerosol component arrived, as the acidity of dew comes from CO2The acid aerosol that absorption or drop dissolve when increasing.Research shows
The time that the volume that the acid-base value of dew depends on condensing dissolves with soil, dust, large volume of dew particle are then corresponding
Need longer setting time, therefore and CO2, sour gas time of contact will be longer, pH value more levels off to CO2Dissolving put down
Weigh constant(pH=5.6).In addition, longer setting time can cause solid-state alkaline matter more by what is be diluted, so as to lead
Cause the pH of dew more relatively acid.
Unlike the rainwater formed in the air in height, air dewfall water condensation is in lower ground table, its forming process limit
Make in subaerial air layer, and surface layer is the main region of local pollutant emission, the pollutant concentration in dew is bright
The aobvious amount being higher than in rainfall, its chemical analysis are also more accurate.In all kinds of Wet depositions, the formation of dew, which has, not to be known
Property and forming amount it is few, therefore it is gathered relatively difficult always, batch capture air dewfall water carries out Physical Chemical Experiment point in addition
Analysis, using its result be used as air environmental pollution indicator, the requirement to collection is higher, there is no at present cost is low, error is small, gather
Efficiency high and Wet deposition harvester easy to operate.
The content of the invention
The purpose of this utility model is to be directed to above-mentioned deficiency of the prior art, there is provided a kind of inverted pyramid formula air dewfall
Laden water collecting device.
Usual dew condensation phenomenon is generally present under night anticyclone weather condition, and condensation substrate is due to ground long wave spoke upwardly
The cooling effect penetrated, its surface temperature are less than dew-point temperature, and condensation, which is formed, reaches balance condensation potential.Under anticyclone weather condition
In night ground heat balanced structure with there are the downward long-wave radiation ALR of solar radiation Ia, air, heat transfer H, latent energy LE on daytime
And Surface long wave radiation GLR.Only pipe has very strong heat transfer H, latent energy LE, Surface long wave radiation GLR cooling on daytime
Effect, because the heat Ia intensity for absorbing solar radiation is big, write in the compensation reached higher than remaining heat flux collective effect
Cooling effect, dew condensation phenomenon can not be formed;Even and if sensible heat, latent heat and the downward long-wave radiation of air at night be present and mend jointly
Cooling effect is repaid, is still integrally negative radiation energy balance due to the cooling effect of stronger ground long-wave radiation upwardly, therefore
There is the possibility of the formation of dew at night.On the other hand because the upward long-wave radiation on night ground has to non-earth's surface dew condensation face
Stronger heat temperature raising effect, and the temperature that one essential condition of the formation of dew is exactly condensation front is less than dew-point temperature, because
This isolation falls on the ground long-wave radiation upwardly, and the suitable dew condensation face of selection is the important ring of the design of dew harvester
Section.
The purpose of this utility model is achieved through the following technical solutions:
A kind of inverted pyramid formula air dewfall laden water collecting device, including support, inverted pyramid formula dew generate pond and dew
Collection vessel, the dew generate pond are made up of polyethylene foam sheet assembly, are fixed in inverted pyramid type on the support, institute
The polyethylene foam sheet upper surface for stating dew generate pond is closely sticked and has polytetrafluoroethylene film, the dew generate pond point bottom
With dew flow export, the dew collection vessel is used immediately below the dew flow export of the dew generate pond point bottom
In collection dew.Wherein polyethylene foam sheet plays with completely cutting off night the effect of long-wave radiation heating upwardly, and the superiors gather
Condensation contact surface of the tetrafluoroethene film as dew, the dew that generation is condensed above are pooled in dew collection vessel and adopted
Sample.The device makes condensation panel cool according to the upward heat effect of isolation night Surface long wave radiation, reaches dew-point temperature
Following principle, so as to promote the condensation of dew on polytetrafluoroethylene (PTFE) panel to be formed.
In the further design of the utility model, each face polyethylene foam sheet of above-mentioned dew generate pond and horizontal plane
Gradient is 20 °~40 °.
In the further design of the utility model, in the upper, middle and lower area of the dew generate pond one side
Domain further respectively has temp probe, for detecting the difference of temperature change at the dew generate pond different height.
In the further design of the utility model, the device also includes open funnel and lifting platform, and the dew is received
Collection container is positioned on the lifting platform, and the bottle mouth position that the open funnel is placed in the dew collection vessel is easy to holding for dew
Connect and collect.
The utility model has beneficial effect following prominent:
Inverted pyramid formula air dewfall laden water collecting device of the present utility model, construction is novel, and stability is good, cost of manufacture
It is low, made using daytime and night ground heat balance, the principle of radiation balance, ensure the reliability that dew is collected, in device
The long-wave radiation for effectively being completely cut off ground with polytetrafluoroethylene (PTFE) using polyethylene in making is heated, and ensure that condensation front dew shape
Into validity, by reliable container rapidly collect condense convergence dew, well collect dew sample, its analysis result
Reliable data are improved for air environmental pollution to support.
