Below by comparing the effect for describing tap type drying device according to an embodiment of the present invention with existing dry arm device.
Wherein Fig. 6-7 shows gas of the tap type drying device of above-mentioned specific embodiment according to the present invention at air outlet
Mobility status is flowed, Fig. 8-9 shows gas of the dry arm device at air outlet between outer tube and air outlet without any air guide structure
Flow mobility status；Figure 10-11, which is shown, installs the dry arm device of a step piece at air outlet between outer tube and air outlet
Air-flow mobility status.Wherein Fig. 6,8,10 are the gas flow rate distribution map at air outlet；Fig. 7,9,11 are transversal in air outlet
The gas flow rate distribution map that face goes out.
When between outer tube and air outlet without any air guide structure, as Figure 8-9, the air velocity on the right side of air outlet is remote
Less than the air velocity on the left of air outlet, the air velocity even 0 in certain places on the right side of air outlet leads to certain places
Form vacuum.Gas flow rate it is uneven, result in that some position flow velocitys at air outlet are excessive, other position flow velocitys are too small,
The wall of the airflow collision air outlet of excessive flow velocity generates very big utter long and high-pitched sounds and noise.
When installing a step piece between outer tube and air outlet, as shown in figs. 10-11, a part of air-flow flows through step piece sky
Gap, although alleviating the non-uniform problem of velocity flow profile to a certain extent, the corner from outer tube to air outlet still deposits
Flow velocity on the left of flow velocity vacuum, air outlet is still excessive.
