Description
Technical field
The present invention relates to smog boxes, and in particular, to can penetration type closing sweep de- settling flux smog box and its detection method.
Background technique
Constantly expand as the level of urbanization is improved with city size, the atmosphere pollution of city especially megapolis is in
Ascendant trend, Air Quality further deteriorate.As the important composition ingredient that haze is formed, aerosol is that solid or liquid are small
Particle disperses and is suspended in the colloidal dispersion system formed in gas medium.Its dispersed phase is solid or liquid fine particle, big
Small is 0.001~100 micron.Urban vegetation is unique lived infrastructure in city, can play and cut down particulate matter etc.
The effect of atmosphere pollution.Plant leaf blade and branch directly can intercept and hold air-borne dust, disengage it from atmospheric environment；Together
When, phytobiocoenose (forest belt, piece woods etc.) can reduce wind speed and change wind direction, lead to the sedimentation of atmosphere pollution, generation lays the dust
Effect.Atmosphere pollution is withheld by the stomata on blade and in suction body by plant, and then is degraded, converted to pollutant
And assimilation, to achieve the purpose that purify air.But how to measure and how many particulate matter be detained on blade, and will not
With the particulate matter (PM of partial size10、PM2.5、PM1Deng) distinguish, there is great difficulty.
Usual way is that method is washed with water in pertinent literature, but since WATER-WASHING METHOD may be by the particle of certain solubilities
Object dissolution, causes the blade amount of laying the dust of measurement less than normal.Also there is document to disclose to blow the particulate matter retained on blade using high wind
It rises, is allowed to be re-suspended into air, thereafter again with the method for the aerosol concentration of different-grain diameter in accurate Instrument measuring air.
But have a disadvantage in that: the air for blowing afloat particulate matter on blade is not inherently pure, and the particulate matter of stripping directly quilt
It blows away, stable aerosol structure can not be formed, therefore have on the accuracy of measurement and greatly influence, test result has very big
Uncertainty.

Meter, and can taking human as controlled wind speed, on blade in the stripping of particulate matter and vapor tight tank body aerosol mixing.
Vacuum pump, i.e. vacuum pump 18 are located at below smog box, guarantee that the air in closed tank body 2 is pumped purification,
Higher vacuum degree can be reached in closed tank body 2.
Operation panel 4 is equipped with temperature height control button, warm-up time control button, fan wind speed control button, fan
Runing time control button, pumping/flush switch control button, washing time control button, tank body air pressure balance control button
Deng.
Ring-like air douche pipe pipeline, i.e. 12 lower section of nitrogen flushing pipeline are distributed a tiny venthole every 5cm,
All gas outlet tiltedly to closed tank body, the i.e. inner wall of closed chamber 2, can spray clean nitrogen after connecting external nitrogen cylinder, right
Inner tank wall is rinsed, and makes to reach pure dustless test environment in vapor tight tank body.
The present invention can penetration type closing sweep de- settling flux smog box detection method includes the following steps:
Plant leaf blade and fine, soft fur brush are placed in valve bag and are sealed before experiment by step 1, open vapor tight tank side door, i.e. side
Valve bag equipped with plant leaf blade is placed in the intracorporal operation pallet 6 of vapor tight tank by lid 15.Close tank body side door, screwing hermetic
Fixing bolt 17.
Step 2 opens headlamp 9, has debugged partial size spectrometer, and partial size spectrometer air inlet is connected vulcanie pipe, rubber
The sebific duct other end extend into tank body center, measurement tank body center at reserved opening at the top of smog box, partial size spectrometer detector interface 8
The particulate in air concentration of position.
Step 3, " pumping " switch on pushing operation panel 4, vacuum pump 18 is started to work, to reach one in tank body
After determining vacuum degree, " flush switch control " button on pushing operation panel 4, vacuum pump 18 stops working at this time, clean nitrogen
By the aperture inward wall injection of ring-like 12 lower section of air douche pipeline, air scour is carried out to the inner wall of closed tank body.By
A period of time to tank body, i.e., after reaching certain pressure in closed chamber 2, presses " stopping " button and stops nitrogen flushing.Repeat aforementioned pumping
For gas-rinsing step until air reaches complete cleaning in vapor tight tank body, the tank body central particles object of partial size spectrometer real-time monitoring is dense
Degree should be extremely low level (lower than 2 micrograms/cubic meter), record the dense of each particles things that time and partial size spectrometer measure at this time
Degree.
Step 4 is stretched by both hands by positive two action panes 5 of tank body by the rubber gloves being fixed on window
Enter to tank interior.Valve bag is opened, hairbrush and blade are taken out, will carefully be swept per a piece of blade surface using hairbrush
Brush.After the completion of whole brushes, variable speed fan 7, and appropriate dither operation pallet 6 are opened, makes the particulate matter of disengaging blade again
It suspends and is scattered in vapor tight tank body.
Step 5 observes the numerical value on partial size spectrometer, and after the value of particulate matter reaches maximum and keeps stablizing, record is at this time
Time and each particles things concentration as ultimate density.After record, fan is closed, i.e. variable speed fan 7, with known
The quality of institute's sample adsorption particulate matter can be calculated in parameter.
Step 6 unscrews sealing fixing bolt 17, opens tank body side door, hairbrush, valve bag and all blades are taken out, then
The valve bag of next plant leaf blade equipped with hairbrush is sealed and is put into tank body.It repeats the above steps and is measured.
The present invention generates air-flow by the rotation that closed tank body apoplexy is fanned, and manually uses hairbrush to sweep in addition de-, by leaf to be measured
The particulate matter that piece sample surfaces are absorbed and retain is blown afloat again, and stable aerosol structure is formed in closed tank body.

8. it is according to claim 1 can penetration type closing sweep de- settling flux smog box, which is characterized in that further include nitrogen punching
Wash pipeline (12)；
Nitrogen flushing pipeline (12) setting is in seal chamber (2)；
Multiple ventholes are provided on the nitrogen flushing pipeline (12).
9. a kind of detection method of smog box, which comprises the steps of:
Step 1: opening side cover (15), matrix is placed in operation pallet (6), side cover (15) are covered；
Step 2: opening headlamp (9), debug partial size spectrometer and partial size spectrometer air inlet is connected to one end of rubber tube；It is described
The other end of rubber tube is extend into closed chamber (2) from the top reserved opening of closed chamber (2)；Measure closed chamber (2) interior air
Particle concentration；
Step 3: vacuum pump (18) being opened by operation operation panel (4), when vacuum degree reaches preset value, nitrogen cylinder is opened and goes out
Port is simultaneously closed vacuum pump (18), and nitrogen is spurted into closed chamber (2) by nitrogen flushing pipeline (12) through venthole；When closed
When pressure in chamber (2) reaches preset value, nitrogen cylinder gas outlet is closed, and record current time, each particles things concentration, point
It is not denoted as the initial concentration of initial time, each particles things；
Step 4: brush is carried out to matrix by action pane (5), watch window (10)；Each particles things are passed through with matrix
In variable speed fan (7) brush to closed chamber (2)；
Step 5: observation partial size spectrometer；After partial size spectrometer numerical stability, current time, each particles things concentration are recorded, point
It is not denoted as the ultimate density of final time, each particles things；
Step 6: according to initial time, the initial concentration of each particles things, the final time, each particles things it is final dense
Degree, obtains the quality of the adsorption particulate matter of matrix.
