Abstract

The device for the receiving of fine dusts is attached to a means of transportation and automatically collects the fine dust during the movement state of the means of transportation. The concentration and/or particle size distribution of the collected fine dusts during the collecting can be determined by a measuring instrument. By the proposed device measured data per function can be transmitted to a receiver.

Description

Beobachtet man die Strömung um ein Fahrzeug kurz nach Ingangsetzen der Parallelanströmung (oder kurz nach Anfahren des Fahrzeugs), so ergeben sich die in 5, 6 und 7. dargestellten Strömungsbedingungen.Observing the flow around a vehicle shortly after starting the parallel flow (or shortly after starting the vehicle), the result in 5 . 6 and 7 , illustrated flow conditions.

Die Strömungskraft wird an der Grenzfläche des Körpers vom Fluid ausgeübt, und zwar durch Schubspannungen in tangentialer Richtung und durch Druck normal zur Oberfläche.The flow force will be at the interface of the body exerted by the fluid, by shear stresses in the tangential direction and through Pressure normal to the surface.

Betrachtet man die Druckverteilung an der Oberfläche, so kann der gesamte (Druck-) Widerstand zerlegt gedacht werden in einen Bug- und einen Heckanteil Fw,B, Fw,H.Considering the pressure distribution at the surface, the whole (pressure) resistance can be thought broken into a bow and a tail portion F w, B , F w, H.

Im „Heck" herrscht immer Unterdruck („Sogkraft"), wodurch der Hauptteil der Widerstandskraft entsteht.In the "tail" there is always negative pressure ("Suction force"), eliminating the bulk the resistance arises.

Im „Bugteil " herrscht in der Stauzone Überdruck, weiter außen entsteht durch die Krümmung der Strömung ein Unterdruck („Sogkraft") siehe 5 [1].In the "front section" there is overpressure in the storage zone, further outwards, a negative pressure ("suction force") is created by the curvature of the flow 5 [1].

Der entgegengesetzt zur Fahrtrichtung wirkende Luftströmung erzeugt an der Stelle der Absaugvorrichtung eine „Sogkraft", siehe 4, 5.The air flow acting in the opposite direction to the direction of travel produces a "suction force" at the location of the suction device, see 4 . 5 ,

Durch die Sogkraft herrscht ein Unterdruck in der Sogkammer Pos. 9. 1.Due to the suction force there is a negative pressure in the suction chamber Pos. 9 , 1 ,

Die Feuchtigkeitssonde (MIS) Pos. 14. 1. steuert die Absperrklappe Pos. 12. 1.
bei trockener Luft „Klappe auf ",
bei feuchter Luft „Klappe zu",
In dem Armaturenbrett kann der Funktionszustand angezeigt werden.The humidity probe (MIS) Pos. 14. 1 , controls the butterfly valve pos. 12 , 1 ,
in dry air "flap open",
in damp air, "shut up",
The functional status can be displayed in the dashboard.

Die aufgewirbelte Feinstaubemission strömt durch das Saugrohr Pos. 6. 1 .The fluidized fine dust emission flows through the suction pipe Pos. 6 , 1 ,

An der Öffnung Pos 13. 1. misst der Durchflussmesser (FQI) die abgesaugte Luftmenge als Option können über ein Staubmessgerät (Aerosolspektrometer) die Feinstaubkonzentration und der Partikelgrößenverteilung analysiert werden.At the opening pos 13 , 1 , If the flowmeter (FQI) measures the extracted air volume, the fine dust concentration and the particle size distribution can be analyzed via a dust measuring device (aerosol spectrometer) as an option.

Über die Umlenkkammer Pos. 15. 1. strömt der aufgewirbelte Feinstaub zu der Unterdruckkammer Pos. 7. 1.About the deflection Pos. 15 , 1 , the stirred-up fine dust flows to the vacuum chamber Pos. 7 , 1 ,

Die Feinstaubemissionen werden durch die Filterkammer Pos. 8. 1. vom Gasstrom abgetrennt.The fine dust emissions are filtered through the filter chamber pos. 8th , 1 , separated from the gas stream.

Die reine Luftstrom in die Sogkammer Pos. 9. 1. und gelangt dann über die Sogschlitze Pos. 3. 1. nach außen.The pure air flow into the suction chamber Pos. 9 , 1 , and then passes over the suction slots pos. 3 , 1 , outward.

Der Differenzdruckmesser (PDISA) Pos. 16. 1. ermittelt den Druckverlust vor und nach dem Filter; in dem Armaturenbrett kann eine Grenzwertüberschreitung optisch oder akustisch angezeigt werden.The differential pressure gauge (PDISA) pos. 16 , 1 , determines the pressure loss before and after the filter; in the dashboard, a threshold may be displayed optically or acoustically.

Ab einem bestimmten Druckverlust wird die Vibrationsvorrichtung Pos. 10. 1. automatisch eingeschaltet und damit der Filter gereinigt.From a certain pressure loss, the vibrating device pos. 10 , 1 , automatically switched on and thus the filter cleaned.

Der abgereinigte Staub wird im Probesammelbehälter Pos. 5. 1. gesammelt.The cleaned dust is in the sample collection Pos. 5 , 1 , collected.

Die Sammelproben können untersucht, analysiert oder direkt entsorgt werden.The Bulk samples can be examined, analyzed or disposed of directly.
