Connected by steam pipe, steam pipe is provided with steam inlet, exhaust outlet is connected with air intake by hot-flow flue.
The operation principle of base case：When needing to dry l Water Paper, steam enters steam pipe from steam inlet
In, then the first air inlet and the second air inlet are flowed into by steam pipe, when steam is from the first air inlet and the second air inlet point
Jin Ru not be after the first drying mechanism and the second drying mechanism, cylinder group starts to dry l Water Paper, and l Water Paper to be dried passes through
After first drying mechanism, enter the second drying mechanism and carry out secondary drying, wherein, the steam of the first drying mechanism is to l Water Paper
Entered after being dried by hot-flow flue in the second drying mechanism to the l Water Paper progress secondary drying in the second drying mechanism.
The beneficial effect of base case is：Set two drying mechanisms ensure that and more effectively drying effect is carried out to l Water Paper
Really；After first air inlet and the second air inlet are connected by steam pipe, the first drying mechanism and the second drying mechanism share one
Individual steam inlet, has saved the equipment cost of drying system；Because the steam in the first drying mechanism is dried to l Water Paper
Still there is certain temperature afterwards, set after hot-flow flue, the steam enters the second drying mechanism by hot-flow flue, with passing through the
The steam that two air inlets enter carries out secondary high-temperature drying to l Water Paper together, it is ensured that drying effect, while real by hot-flow flue
The secondary utilization of the steam in the first drying mechanism is showed, has reduced the steam energy consumption of drying system, saved the energy, and make to make
Paper cost is minimized.
Preferred scheme one：Based on scheme it is preferred, exhaust ports are provided with check valve.Beneficial effect：By setting
Check valve so that steam can only be from the first drying mechanism enters the second drying mechanism, it is ensured that the secondary utilization of the steam
It is smoothed out.
Preferred scheme two：Based on scheme it is another preferably, heat pump is provided with hot-flow flue.Beneficial effect：Heat is set
After pump, heat pump carries out efficient heat-collecting to the steam of process and is integrally formed high-temperature steam, enters finally into the second drying mechanism, it is ensured that
To the drying effect of l Water Paper.
Preferred scheme three：Based on scheme it is another preferably, cylinder group Heterogeneous Permutation set.Beneficial effect：By drying cylinder
After group Heterogeneous Permutation is set, the space of drying mechanism is taken full advantage of, the number of drying cylinder is added, so as to improve the baking of l Water Paper
Dry effect.
Excellent alternative four：Based on scheme another preferred choosing, the first air inlet is provided with close with the second air inlet
Seal.Beneficial effect：After the first air inlet and the second air inlet set sealing ring, it is to avoid steam leaks, so as to ensure
The drying effect of drying system.
Brief description of the drawings
Fig. 1 is the structural representation of the steam drying system embodiment in the utility model papermaking drying portion.
Embodiment
The utility model is described in further detail below by embodiment：
Reference in Figure of description includes：First drying mechanism 101, the second drying mechanism 103, cylinder group 105,
Steam pipe 107, hot-flow flue 109.
The steam drying system in papermaking drying portion as shown in Figure 1, including the first drying mechanism 101 and the second drying mechanism
103, the present invention in the first drying mechanism 101 be the first drying chamber, the second drying mechanism be the second drying chamber, the first drying mechanism
101 and second drying mechanism 103 include cylinder group 105, the Heterogeneous Permutation of cylinder group 105 is set, in the present embodiment, cylinder group bag
6 drying cylinders are included, the first drying mechanism 101 is provided with the first air inlet and exhaust outlet, and exhaust ports are provided with check valve second and dried
