Background technology
The present invention forms principle by natural imitation circle dew, employing is to physical means such as outdoor air suction, compression, condensation, absorption, dew collection and filtrations, realize that artificial dew collection is used for drip irrigation, and reach the purpose of purifying city air and vehicle exhaust with this flow process.Belong to the double technique background that novel dew collection is used for the plantation drip irrigation and administers urban air pollution from using.Belong to imitation the Nature dew formation principle from the invention process method and invent artificial dew new technology flow process, this techniqueflow has manufacture of intraocular dew and purifying city air double technique function.Main technical flows is comprised of " air temperature raising flow process on the ground " and " underground air condensation adsorption flow process " two parts: (1) acrial part: air is after suction on the ground, air is compressed and utilizes solar energy heating to carry out warming and humidifying, make water in air vapour realize maximum saturation; (2) under ground portion: air is admitted to underground cold condensate and adsorption process, mainly is easy to dew by utilization and forms air velocity and transfer Gentle composite glass fiber pipework condensation and adsorbent particles water droplet to realize.Owing to undergroundly be in relative temperature constant state, and meet the above requirement of dew-point temperature " zero " degree, so, by for air temperature raising, airborne steam relative moisture is increased, relatively warm-humid air compressed send under ground portion with dew the flow velocity of easy formation airborne steam is condensed rapidly, forming artificial dew drips, then, obtain the water source in absorptive collection water droplet mode.In air temperature raising, condensation and adsorption process, fine particle, dust and pollutant etc. follow the hydrone coprecipitation to become water droplet in the portion of air, make the process of air setting identical with the process that rainwater forms, simultaneously, it also is the process that is inhaled into air cleaning, be discharged after last air installs the pure fresh air of rear formation after filtration, reach urban air and purify purpose.
The technology of the present invention background belongs to artificial dew collection and drip irrigation greening water-saving category from the Nature air, on the one hand the present invention has by utilization in the air of certain relative moisture and obtains artificial dew water source, be used for the urban afforestation drip irrigation economize, agricultural drop irrigation, the mountain area, arid, semiarid, Gobi desert and Desert Area source of irrigation water, another importance, from administering on the urban air pollution (vehicle exhaust), the present invention is except providing the water saving of drip irrigation water source for urban afforestation, also have purifying city air function, eliminate vehicle exhaust PM10 fine particles for the harm of urban air.
The present invention compares with existing air water-intaking invention, the difference of essence is all arranged: consult similar invention Granted publication number at aspects such as inventive principle, flow path device and application: the device of CN 101614028B＜utilize wind energy from air, to fetch water 〉, this invention is mainly with its special device and the water intaking of suction module.Consult again similar invention Granted publication CN1217070C＜be used for extracting from the surrounding air equipment of drinking water 〉, its inventive principle and use and belong to the different technologies field fully, just water intaking one class device from air.So through looking into all similar inventions, no matter its air suction technology is from water intaking principle and implementation, or range of application and concrete effect etc. all have the difference of essence with the present invention.Another kind of artificial rainfall technology, by in air catalysis on a large scale, produce short time Precipitation Clouds on a large scale, thereby, forming local dewatering, such technology efficiency of producing drinking water is high, but, artificial precipitation does not possess continuation and chronicity from the time, just solves interim damage caused by a drought, can not provide long-term, stable and reliable water source.The present invention forms flow process by imitation dew, can obtain to stablize, reliable and controlled water source, therefore, the present invention be different from fully artificial rainfall technology and other with special material from the air intake technology that absorbs water.The present invention is applied to city or open-air artificial dew and catchments and belong to the New Water Resources development field, is particularly useful for the city and obtains artificial dew and be used for the drip irrigation greening, has the effect of saving urban water.
The present invention compares with existing other air purifying process, and range of application is diverse.Other air purifying process only limits to indoor or the enclosed environment air cleaning, this class air purifying process pollutes for urban air pollution, vehicle exhaust and the PM10 fine particles etc. of open space feels simply helpless, compare with the present invention, belong to diverse range of application.Sharpest edges of the present invention are that city automobile tail gas pollution and the fine particles of eliminating open space are polluted this global problem, countries in the world all do not have reliable solution and technological invention for city automobile tail gas pollution and fine particles pollution at present, so, the invention provides and eliminate the harm that city automobile tail gas brings, alleviate the technical scheme of PM10 fine particles and grey haze suspended solid pollutant in the urban air, effectively purifying city air and vehicle exhaust.
Further contrast the present invention and other artificial air water-intaking invention, other air suction invention belongs to the small air water fetching device, do not support the technique effect of large-scale irrigation, do not possess another important feature of the present invention: administer the especially function of vehicle exhaust PM10 pollution of urban air yet, so, the invention belongs to the catchment air cleaning of drip irrigation and Environments in Urban Open Spaces of artificial dew, be essentially different with existing other air water-intaking technology, its characteristics are as follows: first, natural imitation dew formation principle and flow process are catchmented fully, second, the distinguishing feature that has simultaneously fine particles in purifying city automobile exhaust pollution and the air, the 3rd, for planting greening provides reliable drip irrigation water source, the 4th, by adopting solar energy and small-sized wind energy to provide electric power complementary, dew catchment operation " zero " cost and practicality simple to operate.Five, technical scheme has multifunctional type and sets single functional form.
Further compare the present invention and other indoor or enclosed environment air purifying process, at present, all air purifying process are only limited to for air in indoor air or the enclosure space and purify on the whole world, this class technology is for the air pollution of Environments in Urban Open Spaces, especially at a loss what to do as main pollution source can be described as take city automobile tail gas, up to the present there is not technical solution.The present invention is directed to this global problem and propose solution, air pollution, automobile exhaust pollution, PM10 fine particles and other suspended pollution etc. that are mainly used in Environments in Urban Open Spaces provide air purifying process scheme and implementing method, and this is the maximum difference of the air purifying process of the present invention and other enclosed environment.The present invention is applied to the outdoor air pollutions such as urban transportation arterial highway, residential quarter, roadside and outdoor environment and purifies in the city, simultaneously, carrying out artificial dew catchments for the drip irrigation water source of urban afforestation, has city automobile tail gas clean-up and artificial water intaking double effects.
