Specific embodiment
Below in conjunction with the accompanying drawings embodiments of the invention are illustrated, embodiment is not construed as limiting the invention：
A kind of mechanical-draft cooling tower blast regulation system, it is characterised in that comprising blower fan, is cold below the blade of blower fan
But tower, cooling tower include the water pipe through which, and water pipe includes outlet directed downwardly, water pipe connection heat exchanger and other filter structure,
Heat exchanger is also connected to collecting-tank by water pipe, and collecting-tank is located at the lower section of cooling tower.The reality played by the technical scheme at this place
The technique effect of matter and its realize that process is as follows：Water circulation is sprayed out down from cooling tower, and blower fan drives blade
Rotation is further driven to air current flow, takes away heat, realizes that air quantity is cooled down.The water pipe is distributed between heat exchanger and collecting-tank
Part also include water pump.Water pump provides power for water flowing.
With reference to Fig. 1, the collecting-tank is located at the underface of cooling tower.
With reference to Fig. 3, the collecting-tank is located at the obliquely downward of cooling tower, also comprising inclined wall, can be by cooling tower
Water is directed in collecting-tank.The technique effect of the essence played by the technical scheme at this place and its realize that process is as follows：Incline
Water be not to fall directly in collecting-tank, but wander from inclined wall, further carry out cooling down.
Temperature sensor is included also, the temperature sensor is placed in collecting-tank.The blower fan is also associated with permanent magnetic speed-adjusting
Device.The technique effect of the essence played by the technical scheme at this place and its realize that process is as follows：Blower fan 1 and fan electromotor 2
Logical permanent magnetic speed-adjusting connects (or low-pressure variable-frequency speed regulator), and 4 import of water pump is connected with collecting-tank 7, and the outlet of water pump 4 and heat exchanger 5 enter
Mouthful connection, the outlet of heat exchanger 5 and cooling tower 8 connect, and using permanent-magnet speed governor 9 is manually or automatically adjusted, (or low-voltage variable frequency is adjusted
Fast device), permanent-magnet speed governor 9 (or low-pressure variable-frequency speed regulator) is adjusted forever according to the change of the temperature of collecting-tank 7, if collecting-tank
7 temperature is raised, then judge that the air quantity of blower fan of cooling tower is less, by adjusting permanent-magnet speed governor 9 (or low-pressure variable-frequency speed regulator)
To heighten the rotating speed of fan electromotor 2, increase the air quantity of blower fan 1, that is, the air quantity of increase cooling tower 8, if collecting-tank 7
Temperature is reduced, then judge that the air quantity of blower fan of cooling tower is larger, adjusted by adjusting permanent-magnet speed governor 9 (or low-pressure variable-frequency speed regulator)
The rotating speed of low fan electromotor 2, reduces the air quantity of blower fan 1, that is, the air quantity of reduction cooling tower 8, while ring can also be passed through
The diurnal temperature in border automatically adjusts the air quantity that permanent-magnet speed governor 9 (or low-pressure variable-frequency speed regulator) adjusts blower fan 1.When air quantity demand
During reduction, can pass through to adjust the rotating speed reduction that permanent-magnet speed governor 9 (or low-pressure variable-frequency speed regulator) realizes blower fan, make the energy of blower fan
Consumption is reduced, while start and stop blower fan 1 at short notice is it also avoid, in order to avoid the life-span of motor is impacted.See figures.1.and.2,
This utility model increased permanent-magnet speed governor 9 (or low-pressure variable-frequency speed regulator) realize fan delivery adjust, so as to reach energy-conservation and
The purpose in effective extension device life-span.
In a creative way, each effect of the above is individually present, moreover it is possible to complete the combination of the above results with a nested structure.
It is clear that the technique effect that above structure is realized is realized, discounting for additional technical scheme, this patent title is also
It can be a kind of energy-saving structure.Part details not shown in figure.
It should be noted that multiple schemes that this patent is provided include the basic scheme of itself, it is separate, not mutually
Restriction, but which can also be mutually combined in the case where not conflicting, and reached multiple effects and realized jointly.
