It states experimental rig to be located at below cooling collar, steam (vapor) outlet, steam (vapor) outlet and lower nozzle flange is provided at the top of experimental rig
Connection.
The cooling collar and the cooling vertical setting of outer tube.
Sealing-plug is cased between the steam (vapor) outlet and lower nozzle.
Down tube air collecting chamber is provided between the bottom and lower nozzle of the cooling collar.
The cooling pipe is spiral helicine ripple transverse tube.
The utility model has the advantage that
1, after starting fan, the downward wind of fan output, a part of wind enters in intension air flue and flows downward, this part
Wind takes away the heat that cooling pipe tube wall transfers out, and the heat taken out of is flowed out from gas vent, and another part wind enters outer culvert gas
In road and flowing downward, the heat flowed out from gas vent is discharged into the external world through horn mouth by the outer wind contained in air flue, thereby, it is ensured that
Temperature on cooling pipe is constant always, it is ensured that condensation is gone on smoothly, reach good condensing reflux effect.
2 due to the wind of fan discharge be downward, so that the upper pipe space of cooling pipe forms certain pressure
Downward air pressure play and subtract so that it is guaranteed that being difficult to be diffused into outside pipe from the steam entered in experimental rig in cooling pipe
The beneficial effect of small vapour losses is being basically completed condensation compared to the gas of traditional condensation reflux unit conduit upper region
Afterwards, it inevitably has portion gas to diffuse in external environment, which results in vapour losses.
