At present, the cooling tower of industrial hot water and large-scale refrigeration air-conditioner usually is provided with blower fan in order to accelerate the heat transfer rate of hot water and air in tower.Traditional used for cooling tower blower fan adopts motor driving mostly, and this blower fan generally is made of fan blade, motor and retarder, and motor is connected with fan blade by retarder.But this blower fan is because its motor speed is higher, and the vibration of the mechanical transmission of retarder is bigger, causes its noise when the work operation big, and can cause the tower body vibration, and the power consumption of motor is big simultaneously, is unfavorable for energy-conservation and environmental protection.
In order to solve the problem that traditional used for cooling tower blower fan exists, engineers is carried out research and design one after another, wishes to obtain a kind of novel used for cooling tower blower fan.Wherein, Chinese patent CN02216412.X discloses the water turbine that a kind of blower fan of cooling tower is used, this water turbine can connect to form new hydro powered blower fan with fan blade, this water turbine adopts the fan blade rotation of the circulating water of cooling tower as the motivational drive blower fan, need not adopt motoring in addition again, thereby save electric energy effectively.But, what the water turbine of this patent adopted is through-flow type hydro-turbo, thereby it need be provided with the use that cooling tower could be satisfied in an outlet area in the casing of water turbine, and this space, outlet area is wanted enough could produce greatly enough slowly-releasing space water supply and flowed operating movement.But, can make that like this volume of whole water turbine blower fan is relatively large, be unfavorable for its layout in cooling tower and install and use that simultaneously, water turbine blower fan cost of material and manufacture cost have greatly also been strengthened in the outlet area.
Summary of the invention
The purpose of this utility model is the deficiency at the problems referred to above, and a kind of energy-saving and environmental protection, low noise, the efficient and little electric energy hydrodynamic(al) blower fan of exempting from that takes up room are provided.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of electric energy hydrodynamic(al) blower fan of exempting from, comprise fan blade and the water turbine that is connected with fan blade, this water turbine has the casing of bringing the mouth of a river and water outlet into, water wheels are installed in the casing and be connected in water wheels and fan blade between main shaft, described water wheels are combined flow turbine supercharging water wheels.
Above-mentioned combined flow turbine supercharging water wheels are made up of crown, following ring and blade.
Above-mentioned combined flow turbine supercharging water wheels outer rim is provided with pressurized machine.
Above-mentioned water intake is provided with water guider.
Above-mentioned water guider comprises stator and can realize the speed regulator of multistep speed regulation by changing the stator open angle.
Above-mentioned water outlet is located at the below of water wheels, and is provided with a mixed zone in the casing between water outlet and the water wheels.
Above-mentioned water outlet is the straight-tapered water outlet, or is curved elbow water outlet.
Described in the utility modelly exempt from that electric energy hydrodynamic(al) blower fan structure is simple, energy-saving and environmental protection, low noise and efficient, and need not to be provided with huge outlet area, conserve space and manufacture cost.
Description of drawings
Fig. 1 is the utility model structure sectional view.
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Embodiment
As shown in Figure 1, the electric energy hydrodynamic(al) blower fan of exempting from described in the utility model, reaching the fan blade 1 that is connected with water turbine 2 by a water turbine 2 forms, described water turbine 2 has the casing 21 of bringing the mouth of a river 211 and water outlet 212 into, water wheels 22 are installed in the casing 21 and be connected in water wheels 22 and fan blade 1 between main shaft 23.
Further, above-mentioned water wheels 22 are one to be provided with pressurized machine 221 by crown, the down combined flow turbine supercharging water wheels formed of ring and blade, and this combined flow turbine supercharging water wheels outer rim, in order to improve the water energy utilization ratio of water turbine 2.Above-mentioned water intake 211 is provided with water guider 24, and this water guider comprises stator and speed regulator, and the droop adjustment screw on the speed regulator can be fixing on different angles stator, changes its area of passage (aperture), thereby realize the multistep speed regulation of water turbine 2 and fan blade 1.Above-mentioned water outlet 212 is located at the below of water wheels 22, and be provided with a mixed zone 213 in the casing 21 between water outlet 212 and the water wheels 22, this mixed zone can be with through having discharged the tail water of kinetic energy behind the water wheels 22, the pressure flow that does not discharge kinetic energy in water guider 24 outsides and the gas in the current fully mix the directly water outlet 212 discharge water turbines 2 by being connected in mixed zone 213 of back, leave water wheels 22 working zones, above-mentioned mixed zone 213 and water outlet 212, the general design in outlet area that is different from existing tubular turbine, need not the slowly-releasing space, got rid of the resistance of tail water fully, can improve the rotating speed and the kinetic energy of blower fan greatly water wheels.
Further, above-mentioned water outlet 212 is the straight-tapered water outlet, or is curved elbow water outlet.
The technical solution of the utility model has following advantage:
1) energy-saving and environmental protection. Utilize circulating water excess pressure to promote the hydraulic turbine and drive the fan blade rotation, saved fully Cooling tower is equipped with electric machine for fan, and does not increase the power consumption of water circulating pump, saves energy.
2) efficient. The hydraulic turbine produces kinetic energy and directly drives fan blade, do not need by other decelerators, and with The variation of discharge and air quantity correspondingly changes, make gas-water ratio comparatively stable, in order to guarantee cooling effect.
3) low noise. Cancel traditional cooling tower and be equipped with motor and decelerator, greatly lowered cooling tower fortune The mechanicalness noise in when row, to compare noise lower with the cooling tower of electromechanics deceleration transmission, and the utility model Take water as kinetic energy, power conversion is finished in water flow passage, has controlled and has breathed heavily shake, and the hydraulic turbine can not send dried The noise of disturbing.
