Description
Technical field
The utility model relates to a kind of axial flow hydraulic turbine cooling tower.
Background technology
Existing cooling tower passes through the motor-driven power transmission shaft, and reduces rotating speed, increases moment of torsion by decelerator, makes the cooling tower internal fan rotate with the exhausting heat exchange.Because electrical consumption power is larger, make motor become the main power consumption parts of cooling tower, energy consumption is large, and cooling tower operating cost is high.
And the hydraulic turbine that is used for cooling tower that uses in the market is confined to the lower problem of hydraulic pressure in the cooling tower water inlet pipe.Because hydraulic pressure in the cooling tower water inlet pipe is lower, needs to increase water-aspirator pressure and reach the requirement of hydraulic turbine pressure.Need by water-change pump more or change impeller and realize and increase water-aspirator pressure, so caused the secondary of equipment to drop into, and after changing, pump energy consumption can increase, forming cooling tower energy-conservation, the situation of water pump power consumption.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, the axial flow hydraulic turbine cooling tower of energy savings.
The technical scheme in the invention for solving the above technical problem is: this axial flow hydraulic turbine cooling tower, comprise fan, the decelerator that is connected with fan and water inlet pipe, it is characterized in that: also comprise the exit that is arranged on described water inlet pipe and the hydraulic turbine that is connected with described decelerator.
The hydraulic turbine described in the utility model is axial flow hydraulic turbine.The existing hydraulic turbine generally all uses Francis turbine, because Francis turbine need be arranged on the blower fan bottom, need former blower fan, decelerator etc. are reinstalled in the construction reformation process, bring very large difficulty to installation, and the degree of balance in the time of can't reaching the configuration of former factory after blower fan is reinstalled, produce vibrations and noise in running, affect the service life of equipment.
The hydraulic turbine described in the utility model is connected by shaft coupling with decelerator.
The outlet of the hydraulic turbine described in the utility model is the gradually expanded form structure.The hydraulic turbine described in the utility model is arranged on the exit of water inlet pipe.Utilize the bernoulli principle, form certain negative pressure in hydraulic turbine outlet, to reduce the hydraulic turbine to the requirement of hydraulic pressure, add the characteristics that the water axial flow hydraulic turbine is applicable to large flow, low water head, can utilize the hydraulic pressure of existing cooling tower to transform fully.
Be provided with one on water inlet pipe described in the utility model with the bypass water pipe of water valve, the outlet of described bypass water pipe is lower than the outlet of water inlet pipe.
The below of fan described in the utility model is provided with distributor.
The utility model compared with prior art, have the following advantages and be connected the axial flow hydraulic turbine main shaft with effect and be connected by shaft coupling with power transmission shaft, axial flow hydraulic turbine accesses the cooling tower decelerator by power transmission shaft and reduces rotating speed, increases moment of torsion and make fan rotate the cooling tower of exhausting heat exchange.Configured because power transmission shaft, decelerator, blower fan etc. are former cooling tower, need not during installation to change, only needed axial flow hydraulic turbine is installed on the position of the original motor of cooling tower, installation and maintenance is convenient, engineering time is short, and the blower fan balance need not to readjust, and operates steadily.
The utility model adopts axial flow hydraulic turbine to replace original motor to drive blower fan of cooling tower and rotates.Axial flow hydraulic turbine is installed on the original motor position, and cooling water impacts kaplan turbine runner and produces power main shaft is rotated, the cooling water after acting because deadweight through water inlet pipe outlet gradually expanded form structure with water distribution to distributor.
Description of drawings

Fig. 2 is the scheme of installation of the hydraulic turbine in embodiment.
Label declaration: tower body 1, fan 2, the hydraulic turbine 3, water inlet pipe 4, water valve 5, bypass water pipe 6.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 and Fig. 2, axial flow hydraulic turbine 3 cooling towers comprise tower body 1, fan 2, decelerator and the hydraulic turbine 3.
Fan 2 is arranged in tower body 1, is used for the exhausting heat exchange.Decelerator is connected connection with fan, reduce rotating speed, increase moment of torsion.Be provided with water inlet pipe 4 on tower body 1, the hydraulic turbine 3 is arranged on the exit of water inlet pipe 4.
In the present embodiment, the hydraulic turbine 3 is axial flow hydraulic turbine 3.In the utility model, the hydraulic turbine 3 can be the hydraulic turbine 3 of Francis turbine 3 or other type.
In the present embodiment, the hydraulic turbine 3 is connected by shaft coupling with decelerator.
In the present embodiment, the outlet of the hydraulic turbine 3 is the gradually expanded form structure.The gradually expanded form structure refers to that the outlet diameter of the hydraulic turbine 3 becomes large gradually.
In the present embodiment, be provided with one on water inlet pipe 4 with the bypass water pipe 6 of water valve 5, the outlet of bypass water pipe 6 is lower than the outlet of water inlet pipe 4.Make the rotating speed that can pass through the regulation hydraulic turbine 3 of water adjusting valve 5.In the present embodiment, the below of fan 2 is provided with distributor.
When axial flow hydraulic turbine 3 cooling towers in the utility model use, cooling water enters in cooling tower from water inlet pipe 4 outlets, the hydraulic turbine 3 water that is cooled promotes and rotates, the hydraulic turbine 3 that rotates with transmission of power to decelerator, because decelerator is connected with fan 2, so fan 2 rotates, and completes the task of exhausting heat exchange.
Difference according to system under each operating mode requires to change by the aperture of water adjusting valve 5 water yield of water inlet turbine 3, thereby changes the rotating speed of the hydraulic turbine 3, adapts to various different working condition requirements.
