Description
Technical field
The present invention relates to atmospheric aerosol monitoring and control technical field, particularly relating to a kind of multi-functional aerosol diffusion drying tube.
Background technology
The heterogeneous system that atmospheric aerosol refers to air and collectively constitutes with the solid being suspended in gas or liquid particles thing, its diameter is many in 0.001-100 μm.Along with going deep into of scientific research, find that atmospheric aerosol drastically influence human health, lowers air quality and atmospheric visibility, even Global climate change is produced material impact.At present to using advanced instrument analysis aerocolloidal research, but during to sampling of aerosol, the relative humidity of the internal normal work of instrument itself is less than 40% more more.Additionally, the hygroscopic component in aerosol has obvious moisture absorption to increase phenomenon when relative humidity is more than 50%.Therefore, reducing the relative humidity during sampling of aerosol and necessitate, drying tube just plays decisive role.At present, black carbon is as main extinction material, cloud condensation nucl and has porous and can adsorb the characteristics such as more polluter, becomes the research emphasis of atmospheric pollution.In order to study the impact that atmospheric radiation and cloud are condensed by volatile Organic substance of some black carbon surfaces absorption, the Organic substance and the moisture that remove the black carbon surface of fresh discharge necessitate.Therefore, Mobyneb (be dried, aoxidize and adsorb) drying tube just serves decisive role.
Either field observation or laboratory simulation test at present, the commonly used drying device of people has two classes: (1) utilizes the nafion drying tube of film drying technology.Nafion drying tube is simply possible to use in aerocolloidal being dried, and is applicable to the pneumatic conveying drying of low discharge, it is impossible to meets the demand of specific use, such as removes the volatile organic matter on black carbon aerosols surface.Another reason, business-like nafion drying tube price comparison is expensive.(2) gas is utilized to spread, the diffusion drying tube of silica gel adsorption technology.Business-like diffusion drying tube general only one of which gas passage, in order to reach drying effect so that the length of drying tube is longer, and a diffusion drying tube can only fill a kind of material (silica gel, potassium permanganate particles, activated carbon etc.).If needing to remove the volatile organic matter of black carbon surface absorption, study black carbon characteristic, the drying tube series connection then needing multiple filling different material can be only achieved requirement of experiment, such a process increases the length of whole gas circuit, substantial amounts of particle loss can be caused, exit flow flow diminishes, and directly affects particle diameter distribution, causes the biggest puzzlement to experiment.
Summary of the invention
Present invention aim to overcome that the weak point of existing aerosol diffusion drying tube, a kind of spliced multi-functional aerosol diffusion drying device is proposed, can efficiently accomplish and aerocolloidal be dried, aoxidize and adsorb, shorten gas circuit length, less particle loss and reduction cost, specifically realized by techniques below scheme:
