Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
Main view, the top view of the 1st kind of embodiment of the invention is set forth as depicted in figs. 1 and 2 in embodiment 1,
Fig. 3 and Fig. 4 gives the perspective view of embodiment 1, shown in the 1st kind of embodiment bottom blast device used for cooling tower by air blast
Machine, catch basin 1, umbrella shaped pieces 7 and multiple umbrella shape rings 6 composition, air blower is made of cylinder 2, motor 3 and impeller 4, cylinder 2 it is upper
Lower ending opening, motor 3 are fixed in the internal cavities of cylinder 2 through fixed link 11, and impeller 4 is fixed on the output shaft of motor 3,
During 3 impeller 4 of motor rotates, external air can be blasted through lower part into cooling tower, it will after progress heat exchange
Heat is taken away, and realizes cooling effect, when cooling load is larger, needs spraying cooling water to be cooled down, to improve cooling efficiency.
Air blower is set to after the bottom of cooling tower, in order to avoid on cooling water projection to air blower, it is necessary to which setting is placed cold
But the radical occlusion device of water projection.
Radical occlusion device in embodiment 1 is just by the umbrella shape of multiple umbrella shape rings 6 and top positioned at 2 top of cylinder of air blower
Piece 7 forms, and forms culvert type blocker, multiple umbrella shape rings 6 and the setting of the interval of umbrella shaped pieces 7, and its outer diameter ruler from the bottom to top
Very little to be gradually reduced, the center of each umbrella shape ring 6 offers central openings 9, between the umbrella shape ring 6 and cylinder 2 of bottom, adjacent
Umbrella shape ring 6 between and the umbrella shape ring 6 and umbrella shaped pieces 7 of the top between be connected through connecting rod 8, and formed pass through convenient for gas
Air outlet 10, the lower ending opening of cylinder 2 is air inlet 5, and the periphery of 2 bottom of cylinder is catch basin 1.
In this way, extraneous air can be pumped into from air inlet 5, and is blasted through air outlet 10 during air blower works
Cooling effect is realized into cooling tower.In cooling tower spray, the shower water that falls is blocked through umbrella shaped pieces 7 and umbrella shape ring 6, is sprayed
Water drenching finally drops down onto the catch basin 1 of air blower surrounding, avoids the motor 3 of air blower by spray water projection.
Embodiment 2, as shown in Fig. 5 to Fig. 8, be set forth the main view of the 2nd kind of embodiment of the invention, right view,
Perspective view and cross-sectional view, the radical occlusion device in the present embodiment is by being located at two the first catch basins 12, Duo Ge above air blower
One drainage trough 13 and multiple arch sheets 14 form, and two the first catch basins 12 are arranged in parallel, multiple first drainage trough, 13 compartment of terrain
It is set between the first catch basin 12 and perpendicular, arch sheet 14 is located at the top of the first catch basin 12, during arch sheet 14 is
Between high, shape that two sides are low.The both ends of first drainage trough 13 are communicated through communication port 15 with the first catch basin 12,14 two sides of arch sheet
Edge be located at the surface of the first drainage trough 13, and form ventilation opening between the two sides of arch sheet 14 and the first drainage trough 13,
So that the gas that air blower blasts enters cooling tower.In this way, being divided after being dropped down on arch sheet 14 by the shower water that top is fallen
It flow in the first drainage trough 13 of two sides, then flows into the first side catch basin 12, avoid cold through the first drainage trough 13 again
But splash of the water to air blower 22.
Main view, the right side of the 3rd kind of embodiment of the invention is set forth as shown in Fig. 9, Figure 10 and Figure 11 in embodiment 3
View and cross-sectional view, the radical occlusion device in the present embodiment are made of two second side catch basins 23 and multiple S-shaped water fenders 16, and two
A second side catch basin 23 is arranged in parallel, S-shaped water fender 16 be arranged at intervals between two second side catch basins 23 and with its at
Plumbness.The ventilation opening passed through convenient for air-flow, the vallecular cavity of S-shaped water fender 16 upward are formed between adjacent two S-shapeds water fender 16
The second drainage trough 18 is formed, the both ends of the second drainage trough 18 are communicated with second side catch basin 23, the edge on 16 top of S-shaped water fender
Positioned at the surface of the second drainage trough 18 adjacent thereto, draw in this way, the shower water fallen by top will entirely fall in second
In chute 18, and flowed into second side catch basin 23 through the second drainage trough 18, the splash to avoid shower water to air blower 22.
In order to further ensure the effect of blocking to shower water, the lower end of shown S-shaped water fender 16 is hinged with through pin shaft 19
Movable plate 17, under the action of not by external force, movable plate 17 makes the ventilation opening between two S-shaped water fenders 16 be in closing shape
State can blow afloat movable plate 17 after air blower starting so that ventilation opening is opened, so that outside air is blasted cooling tower.It is living
The unlatching of movable plate 17 can also be controlled by connecting rod.
As shown in Figure 12 and Figure 13, give the usage state diagram of the 3rd kind of embodiment of the invention, shown in cooling tower 20
Lower section be provided with multiple air blowers 22, spray tube 21 is provided in cooling tower 20, when the cooling load of cooling tower 20 is relatively high
When being not enough to extraneous air that medium is cooling, then needs to open spray equipment and carry out spraying cooling, through the invention 3 kinds
One kind of radical occlusion device can avoid air blower and be arrived by spray water projection, extends the service life of air blower 22, avoid electric leakage thing
Therefore generation.
Since air blower is installed to the bottom of cooling tower, the heat of heat exchange module is pushed in the air with the mode of air blast,
Achieve the purpose that cooling, while reducing fog, also save on water source.Air blower selects multiple small-power air blowers, according to
The quantity of temperature height selection starting air blower, has further reached energy-efficient purpose；And can in non-stop-machine situation,
It is replaced and is safeguarded air blower, saved maintenance cost.
