The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated radon gas exposure exposure experiment equipment of the present invention.
As shown in drawings, present device includes: the radon need 3 that radon gas can take place connects fills resource loop 14 to accumulating chamber 4, fill source circulating pump 7 and fill source flux controller 12 adjustment accumulating chamber 4 radon gas and daughter accumulations thereof, air compressed gas source 5 is adjusted the radon gas content in the accumulating chambers 4 by accumulation air flow controller 9 and is had emanometer table 6 to monitor by surveying radon loop 15.Have exposure cycle pump 8 on the exposed circuit 16, be delivered to and expose storehouse 1, expose radon gas flow controller 11 and can adjust and be transported to the radon gas that exposes in the storehouse 1 and the flow of daughter thereof adjusting the radon gas of content and daughter thereof in the accumulating chamber 4.From exposing experiment waste gas safety dumping after discharge pipe 17 is delivered to emission-control equipment 2 adsorption treatment that discharge in storehouse 1.Emission-control equipment 2 has the negative pressure-pumping function can adjust the toxic emission flow by adjusting emission flow controller 13.Air compressed gas source 5 provides fresh air to purge the waste gas that removing exposes storehouse 1 and exposed circuit 16 can directly for exposure storehouse 1 by exposing air flow controller 10 and emission flow controller 13.
Embodiment:
When using radon gas to expose exposure experiment equipment, laboratory animal or measuring instrument are put into exposed storehouse 1 earlier, closedly expose storehouse 1 and expose air flow controller 10, open air compressed gas source 5, exposure cycle pump 8 and fill source circulating pump 7.Adjusting is filled source flux controller 12 and through filling resource loop 14 radon gas that radon need 3 produces is delivered to accumulating chamber 4, regulates accumulation air flow controller 9 and makes the content of radon gas in the accumulating chamber 4 and daughter thereof reach requirement by surveying emanometer table 6 monitoring on the radon loop 15.Regulate exposure radon gas flow controller 11, the radon gas of driving predetermined content and daughter thereof begin to carry out the animal radon gas and expose exposure experiment to exposing storehouse 1; In the experiment, regulate to expose radon gas flow controller 11 and can further adjust the radon gas that exposes in the storehouse 1 and the flow of daughter thereof, exposed circuit 16 can be sent accumulating chamber 4 back to and accumulates once more and recycle exposing partially recycled radon gas in storehouse 1 and daughter thereof; Do not need to accumulate once more the waste gas that recycles and can deliver to safety dumping after emission-control equipment 2 adsorption treatment through emission flow controller 13 and discharge pipe 17.After experiment finishes, close exposure radon gas flow controller 11, exposure cycle pump 8, fill source flux controller 12 and fill source circulating pump 7, open exposure air flow controller 10, purge the waste gas of removing exposure chamber 1, exposed circuit 16 with fresh air.Emission-control equipment 2 has the negative pressure-pumping function, regulates emission flow controller 13 and adjusts exhaust gas flow assurance experiment waste gas through the pollution-free back of complete adsorption treatment safety dumping; After purging removing fully, the flow controller of cutting out air compressed gas source 5 and each loop takes out laboratory animal from exposing in the storehouse 4, finish to test.
