Vent passages 16 pass sequentially through emergency ventilation airduct 36, accident connection fire resisting damper 361, emergency ventilation passage blower fan 362, radioactivity
Filter 37 connects with No. two air shafts 13.The control of normal ventilation connection fire resisting damper 351, accident connection fire resisting damper 361
The output end with radioactivity warning device is held to be connected.
The natural wind in operation tunnel 10 is led to Waste disposal area 2 by axial flow blower 34, passes through disposal area 2 after ventilation
Discharged with the connection tunnel in operation branch tunnel 11, connection tunnel uses duct ventilation, is divided into two of parallel connection according to working condition
Passage, "dead" gas connection to No. two air shafts 13 drain into exterior space under nominal situation.When useless in hoisting process
Thing bag is damaged to produce radioactivity smog and gas, or radgas caused by stacking exceeds set quota to waste bag for a long time
When, radioactivity alarm activation simultaneously closes off the normal ventilation connection fire resisting damper 351 of normal vent passages 15, and opens thing
Therefore the accident connection fire resisting damper 361 in vent passages 16, into accident smoke evacuation filtered model, radioactive dust and gas pass through thing
Therefore the guiding of vent passages blower fan 362 and radioactivity filter 37 quickly drain into No. two air shafts 13 after filtering.Meanwhile start
Waste cleaning and baling equipment in emergent branch tunnel 41, are cleaned and are repacked to the solid waste being scattered.So far by
It is under control and filtering emission in solid radiation and gaseous waste caused by lifting accident, it is therefore prevented that radioactive pollution.
Other unspecified parts are prior art.The present invention is not strictly limited to above-described embodiment.
