But its disadvantage is that the air used to blow up the particles on the blades is not pure, and the blown-off particles are directly blown away, unable to form a stable aerosol structure, so it has a great impact on the accuracy of the measurement. The test results with great uncertainty

Embodiment

[0054] This embodiment provides a self-circulating smoke removal box, the airtight box is located in the stainless steel shell, the strip U-shaped air flushing pipeline is located in the airtight box, and the internal and external pressure protection device, variable speed fan, and lighting are fixed in the airtight box inner wall. The front of the smoke box is made of transparent material for the experimenter to observe and operate. It can also be opened outwards as a sample inlet. There are two arms extending into the operation window. Each operation window is fixed with rubber gloves long enough to ensure that the box internal airtight state. The particle size spectrometer detector interface and reserved other detector and probe interfaces are located on the top of the housing. The operation panel is fixed on the upper surface of the supporting table, the air filter is fixed on the lower surface of the supporting table, and the vacuum pump is located under the supporting t...

Abstract

The invention provides a self-circulation type sweeping-away smog box. An airtight box body is located in a stainless steel shell. A strip type U-shaped air flushing pipeline is located in the airtight box body. An inner and outer pressure protection device, a variable-speed fan and an illuminating lamp are fixed to the inner wall of the airtight box body. A transparent panel is used for observation and operation for an experimenter and can also be opened outwards to be used as a sample inlet, two arm stretching-in operation windows are arranged, each operation window is fixedly provided witha rubber glove which is long enough, and the airtight state inside the box body is ensured. A reserved interface is located at the top end of the shell. An operation panel is fixed to the upper surface of a supporting table, an air filter is fixed to the lower surface of the supporting table, and a vacuum pump is located below the supporting table. The invention further provides a using method ofthe self-circulation type sweeping-away smog box. Granules left on plant leaf samples are released into air again through a blowing-away method and a sweeping-away method, stable and uniform aerosol is formed in the airtight box body, and measuring accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of smoke boxes, in particular to a self-circulating smoke sweeping box and a method for using the same. Background technique [0002] Aerosol is a colloidal dispersion system in which solid or liquid small particles are dispersed and suspended in a gas medium. Its dispersed phase is solid or liquid small particles with a size of 0.001-100 microns, which is an important component of haze formation. Plants can reduce the presence and movement of dust in the air. At the same time, as the wind speed decreases, large particles of dust carried in the air sink to the leaves of trees or the ground, resulting in a dust retention effect. The surface of some plant leaves is fuzzy, and some leaves secrete viscous oils and juices, etc., which can absorb a large amount of environmental pollutants and have an indicator function to repair chemical air pollution; in addition, some of the secretions also have a bactericidal...
