Technical field
The present invention relates to a kind of energy-saving cooling tower with water pressure changing and air quantity regulating waterpower blower unit.
Background technology
Present cooling tower pattern is an induced cooling tower, its shortcoming is: low, the big energy-consuming of efficient, because the energy of input cooling tower has two aspects: an aspect is that another aspect is by advancing the water energy that the tower water pipe is input to the spray of water distribution water injector by the electric energy of motor deceleration machine input.These two energy of input all need big rich.Simultaneously, the noise of cooling tower is directly proportional with 5 powers of rotation speed of fan.The noise of this cooling tower is big, to environmental pollution is big on every side.
And general hydraulic-power ventilation cooling tower has replaced motor and reductor by turbine, directly promotes the blower fan of cooling tower running by turbine.The water energy that it has made full use of former input cooling tower affluence has saved motor and reductor, has realized energy-conservation.But in summer, the required energy of the blower fan of cooling tower wants enough big, rich water can enough satisfy the needs of rotation speed of fan, has caused cooling tower thermal performance can not satisfy technology to its requirement.In the winter time, if blower fan still as the running at full capacity in summer, big because of air quantity, cooling column water temperature is too low, has constituted the cooling tower one of the main reasons of freezing again.
Summary of the invention
Its purpose of the present invention is: a kind of energy-saving cooling tower with water pressure changing and air quantity regulating waterpower blower unit is provided, and it can overcome the deficiency of above-mentioned cooling tower, and it has the efficient height, fault is few, energy-conservation, noise is little.
The present invention is achieved in that a kind of energy-saving cooling tower with water pressure changing and air quantity regulating waterpower blower unit, comprise: packing is set in the tower body, under the tower body collecting-tank is set, water collection device and water distribution water injector are set in the tower, the water distribution water injector is communicated with into tower water pipe, in the air duct at tower body top blower fan is set, describedly advance the tower water pipe and be communicated with the pressure-regulating speed-changing hydraulic propeller by the hydraulic propeller water inlet pipe, the water inlet pipe of pressure-regulating speed-changing hydraulic propeller is communicated with pressue device and hydraulic propeller decompressor respectively, and the hydraulic propeller decompressor is communicated with the hydraulic propeller outlet pipe; The impeller shaft of pressure-regulating speed-changing hydraulic propeller connects blower fan.
Described pressue device is passed through the water inlet pipe of pressue device cross current pressure-regulating speed-changing hydraulic propeller through valve by the pressue device pump outlet; The water inlet of pressue device water pump is communicated with the hydraulic propeller outlet pipe by the pressue device drinking-water pipe.
Described hydraulic propeller decompressor is communicated with the hydraulic propeller outlet pipe by pressure-reducing valve.
The force structure layer outer wrapping building enclosure of described tower body.
Describedly advance the tower water pipe and the hydraulic propeller outlet pipe is a connecting pipe, cut by the water pipe partition panel to be divided into two-way.
Described pressue device water pump and pressure-reducing valve connect Automatic Temperature Control.
The present invention is provided with the pressure-regulating speed-changing hydraulic propeller, the pressure-regulating speed-changing hydraulic propeller is provided with pressue device and hydraulic propeller decompressor, the impeller shaft of pressure-regulating speed-changing hydraulic propeller connects blower fan, can start pressue device and hydraulic propeller decompressor according to the height of temperature, thereby regulate the blower fan wind speed.For example start pressue device in the summer of temperature sweltering heat, the hydraulic pressure that enters turbine increases, and rotation speed of fan increases, and air quantity increases, the thermal performance of cooling tower increases until desired value.In the winter time, start the hydraulic propeller decompressor, portion of water stream is directly entered the water distribution water injector, at this moment, hydraulic propeller diminishes because of hydraulic pressure, and rotating speed diminishes, until stall.It has cooling effectiveness height, when work fault few, saved the electric energy of big blower fan running, having saved general hydraulic-power ventilation cooling tower again needs high kinetic hydraulic energy, in a word, saves a large amount of energy.Simultaneously, avoided the noise pollution of big motor and reductor and cooling tower to freeze, low because of ambient air temperature at night, blower fan can leave low speed, and the noise 5dB that can descend has again reached environmental requirement.
