Description
Technical field
The utility model relates to a kind of experimental provision, particularly a kind of experimental provision can simulating sandstorm or haze true environment.
Background technology
Carry out the research work of sandstorm or haze aspect, need the experimental provision can simulating sandstorm or haze true environment.The wind-tunnel of current China simulation sandstorm true environment has 2, all be built up in Chinese Academy of Sciences cold area arid region environment and Engineering research institute (Lanzhou), but 2 experimental provisions have it obviously not enough, one is that the exhaust outlet of device directly communicates with external environment condition, therefore the sand and dust in wind-tunnel or haze can be made directly to discharge, become the pollution source of sand and dust or haze, experiment and surrounding environment are polluted, cause inevitable Health cost to scientific research personnel and surrounding resident, this experimental provision has received repeated pollution and has complained.Secondly, need constantly to provide sand and dust to device in experimentation, experimental cost is strengthened, also need to increase corresponding utility appliance simultaneously, such as, need the instrument of transport sand and dust for subsequent use.
Summary of the invention
The utility model provides a kind of experimental provision can simulating sandstorm or haze true environment overcoming prior art deficiency.By blower fan, air channel, dirt or haze generator and accessory fan composition, wherein: air channel is by a left side, right two semi-circular air channels and respectively with a left side, the auxiliary air channel that right two semi-circular air channels are communicated with and the closed-loop path that experiment air channel is formed, experiment air channel is provided with view window, left semi-circular air channel is respectively arranged with the transition section and exhaust outlet that are connected with blower fan, blower fan is communicated with left semi-circular air channel by transition section, right semi-circular air channel is communicated with sand and dust generator or haze generator with airduct, sand and dust generator or haze generator are communicated with accessory fan with airduct.Because experiment air channel of the present utility model is closed loop; therefore artificial formation experiment sand and dust or haze are among loop system; fundamentally can eliminate environment to the periphery like this and discharge sand and dust or other objectionable impurities; sand and dust or haze pollution are stopped; protect laboratory and surrounding environment, ensured that experimenter and surrounding people are not subject to the infringement of sand and dust or haze.
A kind of experimental provision of simulating sandstorm or haze true environment of the present utility model, transition section is provided with screen pack, can filters the impurity that blower fan is brought into, make experiment reliably safer.The air outlet of accessory fan is provided with variable valve, and the wind speed that blower fan can be made to provide is able to control according to requirement of experiment.Variable valve is being set for generation of on the accessory fan of sand and dust simultaneously, the concentration of sand and dust can be being controlled, make it reach the parameter of requirement of experiment.
Of the present utility modelly a kind ofly simulate in the experimental provision of sandstorm or haze environment, transition section is tangentially communicated with left semi-circular airduct, and exhaust outlet is communicated with air cleaner.These technical measures by sandstorm simulation in the environment closed, can be eliminated the deficiency that sand and dust are discharged from device, make experiment not produce any negatively influencing to environment and personnel completely.The dust simultaneously used can Reusability.In addition, the utility model experiment that can also carry out being correlated with for simulating haze weather by the haze generator that changes the outfit.

embodiment
The utility model is below in conjunction with embodiment and accompanying drawing explanation.
Of the present utility model a kind of experimental provision of simulating Sand Dust Environment that accompanying drawing 1 provides is by blower fan 1, air channel, sand and dust generator 9 and accessory fan 8 form, wherein: air channel is by a left side, right two semi-circular air channels 14 and 13, and respectively with a left side, the auxiliary air channel 4 that right two semi-circular air channels are communicated with and the closed-loop path that experiment air channel 11 is formed, experiment air channel 11 is provided with view window 10, left semi-circular air channel 14 is respectively arranged with the transition section 2 be connected with blower fan and exhaust outlet 12, blower fan 1 by transition section along be tangentially communicated with left semi-circular air channel 14, and exhaust outlet 12 set on left semi-circular air channel 14 is added is provided with air cleaner, the air cleaner (this structure does not represent on figure) that automobile such as, use.Right semi-circular air channel 13 is communicated with sand and dust generator 9 with airduct 5, and sand and dust generator 9 inside adapter 6 is communicated with accessory fan 8.Transition section 2 is provided with screen pack 3 and blasts foreign material in wind for elimination through blower fan 1.The air outlet of accessory fan 8 is provided with variable valve 7.In the utility model, transition section is tangentially communicated with left semi-circular airduct, and exhaust outlet 12 is communicated with air cleaner.
Sand and dust generator 9 of the present utility model is an airtight container, place dust required by experiment (parameter such as the granularity of dust depends on the requirement of experiment) in it, it there are two interfaces, one for introducing inside by adapter 6, another is for connecting airduct 5, and the end of sand and dust generator 9 inside that wherein adapter 6 is stretched into should be positioned on 9 built-in dust.Adapter 6 is provided with sand and dust variable valve 7.The air-flow that accessory fan 8 produces is introduced and is directly acted on dust by adapter 6 and forms sand and dust by sand and dust generator 9 in use, sand and dust enter pipe 5 by interface 15 and are admitted in air channel 13, the concentration forming sand and dust can be controlled, with the different requirements of satisfied experiment by regulating valve 7.
The utility model sends into wind by blower fan 1 in testing, the air-flow of flowing is formed in pipeline, drive the sand and dust sent into through pipe 5 to form the motion of material recycle in the air channel of device of the sandstorm air-flow of simulation simultaneously, and the phenomenon of view window 10 observation experiment by device is arranged; Or by the experiment that the haze generator that changes the outfit carries out being correlated with in order to simulate haze.Excessive gas when testing can be discharged from exhaust outlet 12, can be purified by air cleaner set on it simultaneously, therefore can not again to environment, and particularly experimental situation produces negatively influencing.
