Description
Technical field
The present invention relates to a kind of PM elution system of building wall and its applications, belong to the prevention and treatment of ecocity haze and rainwater
The technical field of resource utilization.
Background technique
Today's society, haze often appear in each city as diastrous weather phenomenon, and haze is specific weather condition
With the result of mankind's activity interaction.The economy of high density population and social activities will necessarily discharge a large amount of fine particle (PM
2.5, PM10 etc.), once discharge be more than atmospheric air circulation ability and carrying degree, fine particle concentration by continued accumulation, at this time if
It is influenced by quiet steady weather etc., large-scale haze easily occurs.And haze phenomenon is to the people of the city building and health of health
Life, which causes, to be seriously affected.
Meanwhile most cities just will appear urban waterlogging phenomenon whenever rainy season.The reason of urban waterlogging occur has very much, and
Basic reason is urban architecture instead of original natural vegetation, loses strong moisture holding capacity possessed by natural vegetation.Cause
This can not only be subject to benefit to the rainwater of collection if the rain collector of certain capacity can be arranged on the roof of existing building
With, moreover it is possible to effectively alleviate the waterlogging phenomenon in city by the spatiotemporal database of rainwater.
The exterior wall of studies have shown that building has an a degree of regulation of absorbing dust capability, and the PM of exterior wall capture can rainwater from
It is eluted to earth's surface under right souring, so that playing the role of certain laying the dust subtracts haze.However, when the PM of external wall capture reaches
When a certain amount of, if becoming a fine day for a long time, these PM are easily blown in air by wind again, and the air pollutants aggravated in air are dense
Degree, is highly detrimental to the prevention and treatment of city haze.
In living environment, the ornamental plant blade of urban green space has excellent regulation of absorbing dust capability, and gardener author can determine
Phase carries out rainwater sprinkling to ornamental plant surface, while playing pouring, can effectively elute the capture of ornamental plant blade
PM.In contrast, the exterior wall of urban architecture has then lacked the PM elution effect that regularly rainwater sprays and its reaches.
Summary of the invention
The present invention provides a kind of PM elution system of building wall and its applications, can collect urban architecture top layer rainwater benefit
With with building wall PM elution, in one, the PM of external wall capture will be eluted by brainpower insufflation roof rain water, effectively realized
Laying the dust for living environment subtracts haze.

Moisture sensor (16), AMT water level sensor (15), TE/RH series moisture sensor (16) and RS485 intelligent signal conditioner
(17) input terminal connects, and the signal that AMT water level sensor (15) and TE/RH series moisture sensor (16) will test is sent to
RS485 intelligent signal conditioner (17), RS485 intelligent signal conditioner (17) output end are connect with A/D signal adapter (18),
The analog signal detected is converted into the number that C8051F series monolithic (19) can identify by A/D signal adapter (18)
Signal, C8051F series monolithic (19) export result and are converted into analog signal by D/A signal adapter (20) to control water
Corresponding switching task is executed with solenoid valve (8) and blower pump for pipeline (10).
2. the PM elution system of building wall according to claim 1, it is characterised in that: the collection water layer (2) is building
Top layer rainwater processes always high 2/7 of unit；The filter layer (3) is always high 1/7 of architectural top rainwater processing unit, by diameter
The cobble of 10-20cm is simultaneously made of the water-proof metal net of aperture 5cm-10cm package；The water purification layer (4) is architectural top rainwater
It is total high by 1/7 to process unit, is mixed and is formed with active carbon by quartz sand in the ratio of 2-4:1, with filter layer (3), reservoir bed (5)
Contact site is equipped with permeable geotextiles；The reservoir bed (5) is always high 3/7 of architectural top rainwater processing unit.
3. a kind of application of the PM elution system of building wall, it is characterised in that:
When work, in the initial state, building wall PM elutes unit and control start unit in a dormant state, passes through
KG316T time controller (12) cooperation DW17 Series Circuit Breakers (13), CJX2 Series AC Contactor (14) are opened at the appointed time
Power supply starts AMT water level sensor (15) and TE/RH series moisture sensor (16) respectively to reservoir bed (5) and air humidity
It is measured in real time；
During the rainfall, architectural top rainwater processes cell operation, and rainwater falls into collection water layer (2) by protective net (1), then passes through
It crosses filter layer (3) and water purification layer (4) filtration, purification water quality is finally stored in reservoir bed (5), catchment when excessive rainfall water level is higher than
In layer (2) when gap, extra rainwater can be discharged into target structures rain pipe by collecting the overflow pipe (6) of water layer gap；
In no rainy day gas, as humidity reduces in air, the PM content of building surface layer attachment is gradually increased, when air humidity drops
When bottom threshold is arranged down to TE/RH series moisture sensor (16), TE/RH series moisture sensor (16) believes air humidity
The analog signal of breath is transferred to RS485 intelligent signal conditioner (17) reception, and by A/D signal adapter (18) analog signal
It is converted into digital data transmission to give C8051F series monolithic (19), C8051F series monolithic (19) output result passes through D/A
Signal adapter (20) is converted into analog signal to control solenoid valve for water (8) and blower pump for pipeline (10) unlatching, reservoir bed (5)
The rainwater of middle purification enters several laterals (9) pressurization via water-supply-pipe (7) and is sprayed on again by several atomizers (11) mist
Target metope adsorbs metope substance, then forms droplet and slides from metope；
When executing the above process, if there is long-term situation short of rain, the rainwater purified in reservoir bed (5) is repeatedly used for building wall
After face PM elutes unit, it is unable to get supplement, water level decreasing is arranged under threshold value to AMT water level sensor (15) in reservoir bed (5)
In limited time, the analog signal of water level information is transferred to RS485 intelligent signal conditioner (17) and connect by AMT water level sensor (15)
It receives, and analog signal is converted into digital data transmission by A/D signal adapter (18) and gives C8051F series monolithic (19),
C8051F series monolithic (19) exports result and is converted into analog signal by D/A signal adapter (20) to control water electromagnetism
Valve (8) and blower pump for pipeline (10) are closed.
