Description
Technical field
The utility model relates to a kind of atomization of liquid simulation atmospheric aerosol that utilizes and produces, and makes it effectively be applied to the generating means of atmospheric aerosol research.
Background technology
Global climate change and environmental problem are related to whole mankind's existence.For aerocolloidal research is the focus that atmosphere and environmental chemistry scientist pay close attention to always.Gasoloid is solid or the liquid particle thing that is suspended in the gas (being generally air).Gasoloid in the atmosphere plays an important role in Atmospheric Chemistry and radiation balance of atmosphere.In the foundation of part and even global atmosphere model, gasoloid is a very important key factor.The aerosol particle thing is the carrier of many reactions, and the composition of the phase of aerosol particle thing is the key factor that influences these reactions.The heterogeneous phase chemical reaction process takes place and can exert an influence to stratospheric ozone in many studies show that, gasoloid surface, and it is also directly and remote effect global climate, human body health in addition.
In the multiple theoretical model to atmosphere optical radiation property prediction, because limited to the understanding of gasoloid fundamental characteristics parameter, all deviations of various degrees that therefore predicts the outcome are necessary to further investigate the physical and chemical process of atmospheric aerosol.
Summary of the invention
Function of the present utility model is by the atomization of liquid, simulates aerocolloidal generation effectively, for research gasoloid physicochemical property, obtains aerocolloidal base attribute parameter effective way is provided.
The utility model is characterized in that: described aerosol generating device is made up of liquid atomiser, drying tube, sample cell, snubber assembly and vacuum pump; On the medium position of described liquid atomiser bottom a higher-order of oscillation head is arranged, be used for producing gasoloid; Liquid atomiser links with drying tube and common pipe in parallel by valve, drying tube connects with sample cell one end with research institute by threeway with the common pipe other end, according to the sample preparation requirement, select to open one of them valve (dry sample is opened the drying tube valve, and wet sample is opened the common pipe valve).The sample cell other end is connected on the vacuum pump, and gasoloid under the vacuum pump effect, is imported into selected pipeline after producing, and enters the measurement that sample cell is realized correlation parameter.
Adopt the utility model can effectively simulate the generation of atmospheric aerosol, realize the preparation of aerosol sample, for the scientific research atmospheric aerosol provides effective means; The utlity model has integration simultaneously, various devices can be for convenience detach, is convenient to the maintenance of device.
Description of drawings
Fig. 1 is a structural representation of the present utility model, wherein: 1-liquid atomiser, 2-drying tube, 3-sample cell, 4-snubber assembly, 5-vacuum pump, 6-higher-order of oscillation head, 7-valve, 8-valve.
Embodiment
As shown in Figure 1, a kind of device that utilizes atomization of liquid simulation atmospheric aerosol to produce can effectively be applied to atmospheric aerosol research.As shown in Figure 2, aerosol generating device is made up of liquid atomiser 1, drying tube 2, sample cell 3, snubber assembly 4 and vacuum pump 5; A higher-order of oscillation head 6 is arranged in the liquid atomiser 1; Liquid atomiser 1 is leaded up to valve 7 and is connected with the import of drying tube 2, and the outlet of drying tube 2 is connected with the import of sample cell 3; Another road directly is connected with the import of sample cell 3 by valve 8; Sample cell 3 connects the import of snubber assembly 4; The import of the outlet of snubber assembly 4 and vacuum pump 5 links; During work, inject the solution of being studied, in drying tube 2, add drying agent, in snubber assembly 4, add distilled water toward liquid atomiser 1.Selection is opened valve 7 or valve 8 (the system dry sample is opened valve 7 valve-offs 8, and the wet sample of system is opened valve 8 valve-offs 7) control dry sample or wet sample and is entered sample cell 3.Solution under higher-order of oscillation head 6 effect liquid atomiser 1 in atomizing formation gasoloid, the effect by vacuum pump 5 enters sample cell 3, in sample cell 3 substrate sedimentations, finishes sample preparation.Snubber assembly 4 is used for stoping gasoloid to enter vacuum pump 5, prevents that vacuum pump 5 is corroded.
