Embodiment
The present invention is further illustrated below by the mode of embodiment, but is not therefore limited the present invention to
Among described scope of embodiments.
As shown in figure 1, in ventilation for cabin room system of the prior art, the quick-fried ventilation duct 5 in a place where troops were originally stationed and remove
Wet machine airduct 2 is by cabin manhole 1, and the diameter 51 of the quick-fried ventilation duct 5 in place where troops were originally stationed is 200mm；Such as Fig. 2 institutes
Show, in the ventilation for cabin room system after improvement, two new explosion venting pipes 3 and dehumidifier airduct 2 pass through cabin
Room manhole 1, the diameter 31 of every new explosion venting pipe 3 is 120mm, the diameter 21 of dehumidifier airduct 2
All it is 250mm, as shown in figure 3, explosion-proof fan is all arranged at outside the cabin 4, new explosion venting
The one end of pipe 3 is embedded in explosion-proof fan, and the direction of ventilation of two new explosion venting pipes 5 is identical,
The cross section of cabin manhole 1 is ellipse, and the length of the oval major axis 11 is 600mm, the ellipse
Short axle 12 length be 400mm.
The sectional area of the quick-fried ventilation duct 5 in a piece place where troops were originally stationed and a new explosion venting pipe 3 is calculated as follows：
The quick-fried sectional area S1=π r of ventilation duct 5 in place where troops were originally stationed2=π (d/2)2=3.14* (0.2/2)2=0.0314m2,
The new sectional area S2=π r of explosion venting pipe 32=π (d/2)2=3.14* (0.12/2)2=0.011304m
2
The new explosion venting pipes 3 of a piece 120mm reduce 64% compared with the quick-fried sectional area of ventilation duct 5 in 200mm places where troops were originally stationed,
Take in the case of two new ventilations of explosion venting pipes 3, take sectional area and reduce 28%, i.e., former explosion venting
Than two new explosion venting pipe area occupied 0.008792m more than 3 of the occupied area of pipe 52, so, use
New explosion venting pipe 3, which is aerated, may be such that workmen can be easier to access manhole.
It is guarantee cabin after ventilation to ensure closed in space's large area painting operation ventilation principles and requirements
Oxygen content control is within 18%--21% and spray painting is until the quality requirement dried.To ensure ventilation not
It is impacted, 7.5KM, former explosion-proof fan and new explosion-proof fan parameter pair are lifted on the quick-fried power of fan in place where troops were originally stationed
Such as table 1：
Table 1
The quick-fried ventilation duct 5 in place where troops were originally stationed and the new parameter comparison of explosion venting pipe 3 such as table 2：
Table 2
| Sequence | Parameter | The quick-fried ventilation duct in place where troops were originally stationed | New explosion venting pipe | Remarks |
| 1 | Diameter | 200mm | 120mm | Diameter reduces 40% |
| 2 | Length | 4m | 4m | Length is identical |
Experiment is carried out by using the ventilation of the former explosion-proof fan in Tables 1 and 2 and new explosion-proof fan to draw
Data such as table 3：
Table 3
Wind Coverage Calculation formula in table 3：S*V=π r2*V
When new explosion-proof fan is placed on the first deck, the new access of explosion venting pipe 3 ventilation for cabin room is taken,
The one end of two ventilation ducts is embedded in new explosion-proof fan, and the other end is arranged or be embedded respectively additional
Ventilation duct, the length of additional vent pipe is 4m, the length up to 32m of new explosion venting pipe 3, altogether
8 ventilation ducts, which can just be connected to two new explosion venting pipes 3 in cabin bottom, new explosion-proof fan, to be grown
Degree is different, so can reach cabin bottom, another new explosion venting pipe with a new explosion venting pipe 3
3 reach cabin stage casing, can be controlled with the oxygen content for ensureing cabin after significantly more efficient ventilation in 18%--21%
Effect.
As shown in Figure 1, Figure 2 and Figure 3, the oxygen content for guarantee cabin is controlled within 18%--21%
With paint dry mass technological requirement, in addition it is also necessary to increase by a dehumidifier, dehumidifier is arranged at outside cabin 4,
The one end of dehumidifier airduct 2 is embedded in dehumidifier, and dehumidifier airduct 2 is embedded at cabin manhole 1,
The diameter 21 of dehumidifier airduct 2 is 250mm.
To choose 12000HP ship type forepeaks 315.4m3It is ventilation object (foundation company
