Detailed Description

The positional relationship described in the following embodiments includes: the top, bottom, left and right, unless otherwise indicated, are based on the orientation of the elements in the drawings.

Referring to fig. 1, a first embodiment of the present application, an aerosol conditioning system includes a first branch impactor 100, a temperature and humidity regulating device 200, and a sampler 300.

The first radial impactor 100 may be a PM 10 radial impactor, which includes a first radial inlet 110, a first flow conduit 120, a first impingement plate 130, and a first radial outlet 140. The first sub-diameter inlet 110 is used for introducing aerosol flow containing a plurality of particles, the aerosol flow flows to the first impact plate 130 through the first flow guide pipe 120 positioned at the downstream side of the first sub-diameter inlet 110, the first impact plate 130 is positioned at the downstream side of the first flow guide pipe 120 but positioned at the upstream side of the first sub-diameter outlet 140, the first impact plate 130 can enable the particles with larger particle diameters to be remained on the surface of the first impact plate 130 due to inertial impact, and other particles with smaller particle diameters can be discharged from the first sub-diameter outlet 140 along with the aerosol flow, thereby achieving the effect of particle diameter division. In this embodiment, the discharged gas flow contains only particles of PM 10 or less.

The temperature and humidity adjusting device 200 is located at the downstream side of the first branch outlet 140 for adjusting the temperature and/or humidity of the aerosol flow. In this embodiment, the temperature and humidity adjusting apparatus 200 includes a dryer 210 and a condenser 220, and the condenser 220 is located at the downstream side of the dryer 210. The dryer 210 is used for adjusting the humidity of the aerosol flow, and the condenser 220 is used for adjusting the temperature of the aerosol flow.

The sampler 300 is located at the downstream side of the temperature and humidity adjusting apparatus 200, and at least a portion of the particles in the aerosol flow can be collected by the sampler 300. In this embodiment, the sampler 300 is a filter paper cartridge that can be manually sampled. Because the temperature and humidity of the aerosol flow are adjusted by the temperature and humidity adjusting device, the positive deviation generated by the moisture absorption of the particles and the negative deviation caused by the volatilization loss of the semi-volatile substances can be reduced, and the sampling accuracy is improved.

Referring to fig. 2, a second embodiment of the present application is different from the first embodiment in that it further includes a second branch impactor 400 located downstream of the first branch impactor 100 but upstream of the temperature and humidity regulating device 200. The second radial impactor 400 may be a PM 2.5 radial impactor, which includes a second radial inlet 410, a second flow conduit 420, a second impingement plate 430, and a second radial outlet 440. The second branch inlet 410 is for guiding the aerosol flow guided out from the first branch outlet 140, the aerosol flow flows to the second impact plate 430 through the second draft tube 420 located at the downstream side of the second branch inlet 410, the second impact plate 430 is located at the downstream side of the second draft tube 420 but located at the upstream side of the second branch outlet 440, the second impact plate 430 can allow particles with larger particle size to remain on the surface of the second impact plate 430 due to inertial impact, and other particles with smaller particle size can be discharged from the second branch outlet 440 along with the aerosol flow, thereby achieving the effect of particle division. In this example, the discharged gas flow contains only particles having a PM value of 2.5 or less. The rest of the operation principle of this embodiment is the same as that of the first embodiment.

Referring to fig. 3, a third embodiment of the present application is different from the previous embodiments in that the sampler 300 is changed from a filter paper cassette to a Beta gap mass concentration monitor (Beta Gauge) having filter paper for sampling, and the Beta gap mass concentration monitor can automatically analyze the collected sample, thereby realizing automatic collection and analysis and reducing errors of manual sampling.

The above-described embodiments and/or implementations are only for illustrating the preferred embodiments and/or implementations of the technology of the present application, and are not intended to limit the implementations of the technology of the present application in any way, and those skilled in the art can make modifications or changes to other equivalent embodiments without departing from the scope of the technology disclosed in the present application, but should be construed as technology or implementations substantially the same as the present application.
