Description
Technical field
The utility model is related to a kind of ventilator, in particular to a kind of cooling tower water conservancy diversion air duct.
Background technology
Now, cooling tower is widely used in various industries, is the master that the used heat that will be produced in industrial production is taken in air
Want equipment, and cooling tower air duct is indispensable key technology part in cooling tower, whether science is directly closed for the design of air duct
Overall cooling performance, energy consumption and the life-span of cooling tower are tied to, so the research of air duct has great with manufacture in cooling tower industry
Meaning.Traditional cooling tower air duct is simple " tubbiness " profile, only plays basic fence effect.Then develop loudspeaker
The ventilator of shape, but its wind energy utilization is low, noise is big, causes waste and the noise pollution of the energy, simultaneously because motor with
Vapours directly contact so that motor is easily corroded, reduces the service life of motor.
To solve the above problems, the utility model provides a kind of cooling tower water conservancy diversion air duct, introduces aerodynamic design,
Compared to traditional air duct, there is more preferable refrigeration, energy consumption is lower, and the life-span is longer, and noise is lower.
Utility model content
The utility model overcomes that existing cooling tower air duct air outlet wind speed profile is uneven, and wind energy utilization is low, easily
Vortex is formed, there is the de- wall of air-flow, motor suffers that vapours corrodes, the low phenomenon of service life, there is provided a kind of cooling tower is led
Stream wind, theory is homogenized using gas flowfield, and air-flow can be made uniform, and airflow kinetic energy loss is few, reduces vortex, reduction negative pressuren zone
The de- wall phenomenon of area, airless, mitigates and tower humid air to air inlet backflow, makes air outlet sectional wind velocity evenly, increases electricity
Machine service life.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：
A kind of cooling tower water conservancy diversion air duct, including air duct, the support frame in air duct, the fan below support frame
Leaf, the motor above support frame, the air duct is made up of diversion section, frame sections and closing in section, and the frame sections are arc
Type, tangent with diversion section, the closing in section of the air duct is ellipse, and tangent with frame sections, support frame as described above center is installed upward
Flow guide sleeve, the flow guide sleeve is ellipse, and the motor is placed in flow guide sleeve.
Further, closing in section of the flow guide sleeve higher than air duct.
Further, the flow guide sleeve top sets opening.
Further, the closing in section is identical with flow guide sleeve radian.
Compared with prior art, the utility model has the advantages that：
Make air-flow uniform, airflow kinetic energy loss is few, reduces vortex, reduce negative pressuren zone area, the de- wall phenomenon of airless subtracts
Gently go out tower humid air to be flowed back to air inlet, make air outlet sectional wind velocity evenly, reduce the energy consumption of motor, protect motor not receive
Vapours is destroyed, and improves the service life of motor.
Brief description of the drawings
Fig. 1 is a kind of structure chart of cooling tower water conservancy diversion air duct of the present utility model.
In figure：1. air duct, 2. diversion section, 3. frame sections, 4. closing in section, 5. support frame, 6. flabellum, 7. motor, 8. water conservancy diversion
Set, is 9. open.
Specific embodiment
1 pair of specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of cooling tower water conservancy diversion air duct of the utility model, including air duct 1, the support in air duct 1
Frame 5, installed in the flabellum 6 of the lower section of support frame 5, installed in the motor 7 of the top of support frame 5, the air duct 1 is by diversion section 2, fuselage
Section 3 and closing in section 4 are constituted, and the frame sections 3 are camber, tangent with diversion section 2, and the closing in section 4 of the air duct 1 is ellipse,
Tangent with frame sections 3, upward flow guide sleeve 8 is installed at the center of support frame as described above 5, and the flow guide sleeve 8 is ellipse, the motor 7
It is placed in flow guide sleeve 8.Motor 7 drives flabellum 6 to rotate, and air is by inside the at the uniform velocity progress cooling tower of diversion section 2, expanding air
With hot water contacts face, thermal current is arc by frame sections 3, frame sections 3, dynamic pressure is reduced by expanding air-out area, then
Thermal current is streamed to outside cooling tower due to air-flow de- wall and whirlpool, last hot gas by closing in section 4, then will not occur.Simultaneously
When thermal current is by motor 7, due to the flow guide sleeve 8 that the periphery of motor 7 is installed so that motor 7 will not with vapours directly contact, from
And protect motor 7 not weather, the top of flow guide sleeve 8 sets opening 9, contributes to motor radiating, increases the service life of motor 7.Lead
Stream set 8 is all ellipse with closing in section 4 and radian is identical so that flow velocity is more uniform when thermal current is by closing in section 4, is difficult to produce
Raw whirlpool.The utility model can make that air-flow is uniform and kinetic energy rejection is few, reduce vortex, reduce negative pressuren zone area, airless
De- wall phenomenon, mitigates and tower humid air to air inlet backflow, makes air outlet sectional wind velocity evenly, reduces the energy consumption of blower fan,
Heated vapor is not destroyed to protect motor, improves the service life of motor.
Finally it should be noted that:Above example is merely to illustrate the technical scheme of the application rather than to its protection domain
Limitation, although being described in detail to the application with reference to above-described embodiment, those of ordinary skill in the art should
Understand:Those skilled in the art read still can be to applying after the application specific embodiment carry out a variety of changes, modification or
Person's equivalent, but these changes, modification or equivalent, are applying within pending claims.
