Description

Water and electricity double-drive device, complementary energy generator set and cooling tower Technical Field The application relates to the technical field of power conversion of surplus water in circulating backwater, in particular to a hydropower double-drive device, a surplus energy generator set and a cooling tower. Background In an industrial cooling circulating water system, a traditional medium-large cooling tower fan is usually driven to run by adopting a motor (pure electric energy) -a long transmission shaft-a speed reducer. The fan motor of the cooling tower runs for a long time, has high power consumption and continuously generates high electric charge. The circulating backwater is distributed into the cooling tower through the water distribution pipe, the splashing and thinning of the spray head falls down, and the heat exchange and the cooling are carried out through the filling flow channel, so that the surplus water kinetic energy exists in the circulating backwater and is released to be wasted in the outlet plane of the water distribution spray head (the water distribution spray head contacts with the atmosphere) in the cooling tower. How to use the surplus kinetic energy of the circulating backwater to the cooling tower fan becomes a problem to be solved urgently. Disclosure of utility model In order to apply the surplus kinetic energy of the circulating backwater to the fan of the cooling tower, reduce the waste of the surplus kinetic energy, save the electricity cost and simultaneously generate the effect of generating electricity benefits, the application provides a hydropower double-drive device, a surplus energy generator set and a cooling tower. In a first aspect, the application provides a hydro-electric dual-drive device and a complementary energy generator set, which adopts the following technical scheme: The water-electricity double-drive device and the complementary energy generator set comprise a water turbine and a permanent magnet synchronous motor, wherein a water inlet pipe and a water outlet pipe are arranged on the water turbine, the water outlet pipe is communicated with a water distribution pipe in a cooling tower, an output shaft of the water turbine drives a main shaft of the permanent magnet synchronous motor to rotate, and an output end of the main shaft of the permanent magnet synchronous motor is connected with a transmission shaft of the cooling tower. Through adopting above-mentioned technical scheme, when the fan of cooling tower needs to rotate, contain three kinds of driving methods: 1. The water kinetic energy is sufficient, namely, only the water turbine runs through the permanent magnet synchronous motor, the transmission shaft and the speed reducer in the wind barrel to drive the fan to run, the transmission shaft and the speed reducer in the wind barrel are components in the cooling tower (particularly, when only the water turbine runs, the rotating shaft of the permanent magnet synchronous motor is idle and is equivalent to a transmission shaft, and at the moment, the permanent magnet synchronous motor does not consume electricity and generate electricity and does not generate resistance); 2. the hydraulic turbine works, and meanwhile, the permanent magnet synchronous motor is electrified to generate a rotating moment, and the fan is driven to run through a transmission shaft and a speed reducer in an air duct in a mode of 'hydraulic energy+compensation electric energy'; 3. The absolute kinetic energy is that a permanent magnet synchronous motor (pure electric energy) runs, and a fan is driven to run through a transmission shaft and a speed reducer in an air duct. The application can drive the cooling tower fan to run by adopting a mode of 'water kinetic energy+compensation electric energy', if the water return surplus energy is low and the environment temperature is high (Wen Tianqi in summer), the water outlet temperature of the cooling tower can not reach the production process requirement by driving the fan to run only through the water turbine (low rotating speed and small air quantity), and external power (differential power) is needed to increase the rotating speed of the fan to increase the air quantity. The method has the advantages that surplus kinetic energy of circulating backwater is converted and applied to the fan of the cooling tower, waste of the surplus kinetic energy is reduced, and electricity cost is saved. The hydraulic turbine comprises a permanent magnet synchronous motor, a hydraulic generator, an elastic coupling, a speed increaser and a hydraulic generator, wherein the speed increaser is one-in two-out type, an output shaft of the hydraulic turbine is connected with an input end of the speed increaser through the elastic coupling, and two output ends of the speed increaser are respectively connected with a main shaft of the permanent magnet synchronous motor and an input shaft of the hydraulic generator. The speed increaser
