Description
Technical field
The present invention relates to cooling tower technical field, especially a kind of cooling tower cloth wind structure.
Background technology
Cooling tower (The cooling tower) is by the use of water as circulating coolant, absorbs heat dissipation from a system
Into air, to reduce the device of water temperature;It is to carry out cold and hot exchange after contacting with air flow using water to produce steam that its is cold, is steamed
Vapour volatilization takes away heat and reaches the principles such as evaporative heat loss, convection heat transfer' heat-transfer by convection and radiant heat transfer to disperse industrially or be produced in refrigeration air-conditioner
Raw waste heat reduces the evaporating radiator of water temperature, and to ensure the normal operation of system, device is generally tubbiness, therefore named to be cold
But tower.
Mechanical ventilation type cooling tower is applied quite varied in many domain classes such as megastore, hotel, gas station at present, but
It is that cooling tower can produce very big noise in the course of the work, its noise pollution strength of sound source can typically reach more than 80dB (A)
It is even more big, influence the normal life of staff around and resident.With society gradual progress, the continuous development of science,
Requirement of the people for residing living environment and working environment also improves constantly therewith, the harmfulness of noise on human also slowly by
People recognize.More then it is engaged in the researcher of cooling tower relevant industries starts to how to realize that the noise reduction of cooling tower enters
Row research, specifically how while cooling tower noise reduction is ensured, and does not influence the heat transfer property of cooling tower, always cold
But the problem of tower noise abatement, thus the control to cooling tower noise has become cooling tower industry urgent problem.
It is also restrained for the setting height(from bottom) of cooling tower in some special occasions.Required based on some above-mentioned, one
Kind enclosed bottom blast formula cooling tower structure is suggested.The structure can solve the above problems, and reach the standard of environmentally friendly noise.
But at the same time also there are some research and development problems, the enclosed bottom blast formula cooling tower sets the transmission parts such as blower fan, motor
To the bottom of cooling tower, using bottom blast mode, cool ambient air is set to enter in tower, while the recirculated water in packing layer will
Flowed to from above following, cool ambient air enters in tower to cool to the recirculated water that flows through packing layer, while to ensure to blast
Air quantity can not be excessive, cross conference and cause fine liquid particles to be blown out by wind from tower top, it is too small recirculated water to be cooled (up to not
To design requirement), the recirculated water that also ensure to flow down from packing layer can not be flowed on ground from blower fan, motor, can only return to tower
In the collecting-tank at bottom.
The noise of bottom blast formula cooling tower mainly has water drenching noise, fan noise, mechanicalness noise, tower body noise, passes through
Steady-state noise caused by the collecting-tank for the droplets impact bottom that large area continuously falls is referred to as the water drenching noise of but tower.Water drenching is made an uproar
Process caused by sound is that the recirculated water in cooling tower flows from top to bottom, by packing layer, then falls into the tank for cooling down tower bottom
In caused by impact noise, be called water drenching noise.Water drenching noise intensity and the volume for flowing through recirculated water in the unit interval, stream
Amount is related to overboard height.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of bottom blast formula cooling tower cloth wind structure, can be with noise reduction
And can ensures cooling effect simultaneously.
It can cause to cool down the disorderly inequality of wind wind speed in existing guiding device structure, certain difficulty be present in installation, and
To the good water conservancy diversion direction of recirculated water neither one.The bottom blast formula cooling tower cloth wind structure of the present invention can both ensure to pass through
The recirculated water of packing layer can only be returned in cooling tower underdrain pond, rather than is then flowed into after falling on blower motor on ground,
In turn ensure that cooling wind that bottom blasts enters inside tower body directly to contact with recirculated water simultaneously to be cooled down.
The technical solution adopted in the present invention is:Bottom blast formula cooling tower cloth wind structure, including it is arranged on cooling tower
Cloth wind structure between packing layer and air blower, the cloth wind structure include upper wind plate, lower air distribution plate, gusset piece, upper wind plate,
The upper end edge gusset piece of lower air distribution plate is circumferentially equidistant to be alternately arranged, and upper wind plate, the lower end of lower air distribution plate are connected to air blower week
On the ventilating duct of side, upper wind plate, lower air distribution plate and ventilating duct, gusset piece are by the recirculated water after by packing layer and air blast
Mechanical, electrical machine etc. is isolated, and upper wind plate, the lower end of lower air distribution plate are set to cooling tower sidewall slope so that recirculated water can be along
The upper wind plate, the lower air distribution plate that are obliquely installed flow into the collecting-tank of bottom of towe, play water conservancy diversion, while upper wind plate, lower cloth wind
The setting of plate reduces the overboard height of recirculated water, slow down the speed of water when dropping to collecting-tank, is made an uproar so as to reduce water drenching
Sound, there is certain interval between upper wind plate and lower air distribution plate, make the cold wind that air blower bloats by gap directly to by filling out
The recirculated water of the bed of material is cooled down, and improves the heat transfer efficiency of cooling tower.
Further, the angle of inclination of upper wind plate is 20 to 50 °, ensures that recirculated water can be fallen into collecting-tank, simultaneously
It slow down overboard speed when arriving collecting-tank.
Further, the angle of inclination of lower air distribution plate is 20 to 50 °, ensures that recirculated water can be fallen into collecting-tank, slows down
Overboard speed when arriving collecting-tank.
Further, upper wind plate, lower air distribution plate are adopted and are formed from aluminium, and further cooling water is cooled down.
Further, upper wind plate, lower air distribution plate are that width gradually broadens from upper end to its lower end, cloth wind in guarantee
Only there is less gap between plate, lower air distribution plate, avoid recirculated water from falling on the air blower in ventilating duct, among it less than two
Side is set, and recirculated water is fallen into along upper wind plate, lower air distribution plate in collecting-tank, ensure that the water conservancy diversion work to recirculated water
With.
The beneficial effects of the invention are as follows:
(1) structure setting of the upper and lower air distribution plate of the present invention plays guide functions to recirculated water, is returned to cooling tower bottom
Collecting-tank in, prevent recirculated water from dropping to the mechanical, electrical machine of bottom blast, on decelerator, short-circuit protection effect played to motor, is increased
The service life of motor, air blower is added.
(2) the cooling wind that the structure setting of the upper and lower air distribution plate of the present invention can blast bottom blower fan enters in tower, with following
The directly contact of ring water is cooled down, while air distribution plate is further cold to recirculated water progress using good materials of thermal conductivity factor such as aluminium
But, the cooling effectiveness of cooling tower is improved.
(3) structure setting of the upper and lower air distribution plate of the present invention reduces the water drenching height of recirculated water, is made an uproar so as to reduce water drenching
Sound.
