The device is composed of a draught fan, a closed loop, a sandstorm generator or a haze generator, and an auxiliary draught fan, wherein the closed loop is composed of a left semi-annular air flue, a right semi-annular air flue, an auxiliary air flue and an experiment air flue, and the auxiliary air flue and the experiment air flue are communicated with the left semi-annular air flue and the right semi-annular air flue respectively. The sandstorm generator or the haze generator is communicated with the right semi-annular air flue through an air pipe, and the auxiliary draught fan is communicated with the sandstorm generator or the haze generator through an air pipe. According to the experimental device, the sandstorms can be simulated in a closed environment, the defect that sand dust or haze is discharged out of the device can be completely eliminated, and there are no negative experimental influences on the environment. According to the experimental device, the haze weather can be simulated by replacing the sandstorm generator with the haze generator so that relevant experiments can be performed.

Technical field
The present invention relates to a kind of experimental provision, particularly a kind of experimental provision that can simulate sandstorm or haze true environment.
Background technology
Carry out the research work of sandstorm or haze aspect, need to have the experimental provision that can simulate sandstorm or haze true environment.The wind-tunnel of the sandstorm of China's simulation at present 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, the one, the exhaust outlet of device directly communicates with external environment condition, therefore can make sand and dust or haze in wind-tunnel directly discharge, become the pollution source of sand and dust or haze, experiment and surrounding environment are polluted, scientific research personnel and surrounding resident are caused to inevitable Health cost, and this experimental provision has been subjected to repeated pollution complaint.Secondly, in experimentation, needing constantly provides sand and dust to device, and experimental cost is strengthened, and also needs to increase corresponding utility appliance simultaneously, for example, need to have the instrument of transport sand and dust for subsequent use.
Summary of the invention
The invention provides a kind of experimental provision that can simulate sandstorm or haze true environment that overcomes prior art deficiency.By blower fan, air channel, dirt or haze generator and accessory fan composition, wherein: the left side of serving as reasons, air channel, right two semi-circular air channels and respectively with a left side, the Bi HeMeter-loop road that the auxiliary air channel that right two semi-circular air channels are communicated with and experiment air channel form, on experiment air channel, be provided with view window, on left semi-circular air channel, be respectively arranged with the transition section and the exhaust outlet that are connected with blower fan, blower fan is communicated with left semi-circular air channel by transition section, on right semi-circular air channel, be communicated with sand and dust generator or haze generator with airduct, on sand and dust generator or haze generator, be communicated with accessory fan with airduct.Because experiment of the present invention air channel is closed Meter-loop road; therefore artificial formation experiment sand and dust or haze are among loop system; environment to the periphery be can fundamentally eliminate like this and sand and dust or other objectionable impurities discharged; having stopped sand and dust or haze pollutes; protected laboratory and surrounding environment, ensured experimenter and around personnel be not subject to the infringement of sand and dust or haze.
A kind of experimental provision of simulating sandstorm true environment of the present invention is provided with screen pack on transition section, can filter the impurity that blower fan is brought into, makes to test safer reliable.On the air outlet of accessory fan, be provided with variable valve, the wind speed that can make blower fan provide is able to according to requirement of experiment control.On the accessory fan for generation of sand and dust, variable valve is set, can controls the concentration of sand and dust, make it reach the parameter of requirement of experiment simultaneously.
In a kind of experimental provision of simulating Sand Dust Environment of the present invention, transition section is tangentially communicated with left semi-circular airduct, and exhaust outlet is communicated with air cleaner.These technical measures can, by sandstorm simulation in the environment of sealing, be eliminated the deficiency that sand and dust are discharged from device completely, make experiment not produce any negatively influencing to environment and personnel.The dust using can Reusability simultaneously.In addition, the experiment that the present invention can also be correlated with for simulating haze weather by the haze generator that changes the outfit.
