Description
A VENTILATING ASSEMBLY FOR COOLING TOWER
Technical Field
The present invention relates to a ventilating assembly for a cooling tower and more particularly to such assembly having a hydropower device for rotating the ventilating fan and the cooling tower having installation of the ventilating assembly therein.
Background Art
One important factor that affects the performance of the cooling tower is the speed of the air flowing through the cooling tower, especially the mechanical draft tower that uses fan for controlling flow rate of the air for cooling. The rotation of the fan is driven by a motor to draw the outside air into the cooling tower for removing heat from the water, such as heat exchange with the refrigerant in the condenser of the compress or of the cooling system. The circulation of the air in the cooling tower depends on the size of the fan in the large cooling system. The more the amount of hot water (water that exchanges heat thereof with the refrigerant) circulated in the system, the larger the size of the cooling tower is. This requires a motor having sufficient power to drive the rotation of the fan in order to obtain sufficient air volume in the air circulation for cooling system. This causes a burdensome electricity expenses for the operation of the said motor.
Thai Petty Patent No. 12661 disclosed an energy-saving equipment for the cooling tower consisting of a motor-substitute power equipment for driving the ventilating fan of the cooling tower through the installation equipment. The inside of the motor-substitute power equipment has impellers that receive fluid pressure. The impellers rotate and transmit the power to the ventilating fan of the cooling tower through the installation equipment. The energy-saving equipment for the cooling tower according to this invention functions as the power source for driving the ventilating fan of the cooling tower instead of the motor.
Based on the mechanism of the energy-saving equipment for the cooling tower according to the above petty patent, the fluid with high pressure is released through the fluid pipe into the motor-substitute power equipment having impellers therein. The impellers receive the pressure of the fluid and then rotate and transmit the power to the ventilating fan of the cooling tower through the installation equipment. The fluid that passes through the motor-substitute power equipment will flow out to circulate to the cooling tower system.
However, there is a limitation to the energy-saving equipment for the cooling tower according to the above petty patent in case of releasing the fluid with low pressure through the fluid pipe into the motor-substitute power equipment. The fluid pressure is not sufficient for driving the impellers of the motor-substitute power equipment. Therefore, the motor-substitute power equipment cannot transmit the sufficient power to the ventilating fan. The performance of the energy-saving equipment for the cooling tower is reduced.
The inventor of the present invention comes up with a mechanism for increasing the flow rate of the air by driving the ventilating fan of the cooling tower to increase the amount of air circulation and ventilation in the tower efficiently. The energy-saving equipment above also functions as a power source for driving the ventilating fan of the cooling tower instead of the power source from the motor. This is efficient energy use and cost saving with regard to electricity consumed by the motor.
Summary of Invention
The present invention relates to a ventilating assembly for a cooling tower comprising a hydropower device (1), a ventilating fan (2), a hub (3), a first fluid pipe (4) and a pump (6). The hydropower device (1) is connected to the first fluid pipe (4) whereby the water is driven to flow from the first fluid pipe (4) to the hydropower device (1) by the pump (6) which controls water pressure. The water flowing through the hydropower device (1) in which a propeller is mounted to transmit power via the hub (3) for rotating the ventilating fan (2). One end of the hub (3) is connected to the hydropower device (1) and another end of the hub (3) having a shaft is connected to the ventilating fan (2). The water which transmitted power to the ventilating fan (2) and came out of the hydropower device (1) is then circulated into the heat transfer process.
An objective of the present invention is to provide the energy-saving equipment for the cooling tower with a mechanism for increasing air flow rate to remove the limitation in case of releasing fluid with low pressure through fluid pipe into the hydropower device (1) in combination with the pump (6) for controlling fluid pressure
