Hydroelectric hybrid device of cooling tower

Abstract

A hydroelectric hybrid device of a cooling tower relates to a power system of a cooling tower. A main motor is omitted, and a hydroelectric all-in-one machine is mounted at a position of the original motor outside an air duct of the cooling tower, and consists of a water turbine and an auxiliary motor used for power compensation. A combination mode includes that a joint force output shaft of the water turbine and the auxiliary motor is connected with a transmission shaft, the auxiliary motor also can be combined with an output shaft of the water turbine by a belt pulley or a gear train and then a combination of the auxiliary motor and the output shaft of the water turbine is connected with the transmission shaft, the transmission shaft is connected with a speed reducer, and the speed reducer is connected with a fan. A water inlet of the water turbine is connected with a water feeding pipeline of the cooling tower, a water outlet of the water turbine is connected with a drain pipeline, and the drain pipeline is connected with a water distributing system of the cooling tower and provided with a bypass pipe. The main motor is omitted, the hydroelectric hybrid device is provided with the auxiliary motor matching with the water turbine, kinetic energy of the water turbine is sufficiently utilized, energy consumption of the high-power main motor is saved, and normal running of the hydroelectric all-in-one machine is guaranteed under the condition that the kinetic energy of the water turbine is insufficient by the aid of the low-power compensating motor. Simultaneously, damage to running of the motor due to the excessively close distance from water inlet and outlet pipes of the water turbine to blades of the fan is avoided.

Description

technical field [0001] The present invention relates to cooling tower power systems. Background technique [0002] At present, in addition to the traditional motor reducer as the power source for cooling tower fans on the market, a device that uses the excess flow and water pressure of the cooling tower water supply pump to drive the fan has appeared in recent years to achieve energy saving by using the surplus. purpose, but because the excess flow and water pressure of the water pumps of each unit are different, some excess flow and water pressure can meet the power needs of the fan after converting power, and most of the excess flow and water pressure cannot meet the operation of the fan after working through the water turbine. In this way, the device cannot be used to transform the fan, but some energy is surplus and cannot be used, and because the structure removes the original reducer, two water turbine inlet and outlet pipes with larger diameters are added. The distan...
