Description
Technical field
The utility model is related 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 flowing using water to generate steam that its is cold, is steamed
Vapour volatilization takes away heat and reaches the principles such as evaporative heat loss, convection current heat transfer 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, and therefore named is cold
But tower.
Mechanical ventilation type cooling tower is applied very extensive in many domain class such as megastore, hotel, gas station at present, but
It is that cooling tower can generate very big noise during the work time, noise pollution strength of sound source can generally reach more than 80dB (A)
Even bigger, influences 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 is also continuously improved therewith, the harmfulness of noise on human also slowly by
People recognize.More then be engaged in the researcher of cooling tower relevant industries start to how to realize the noise reduction of cooling tower into
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 have become cooling tower industry urgent problem to the control of cooling tower noise.
It is also restrained for the mounting height of cooling tower in some special occasions.It is 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, which sets the transmission parts such as wind turbine, motor
To the bottom of cooling tower, using bottom blast mode, cool ambient air is made to enter in tower, while the recirculated water in packing layer will
From flow direction above in the following, cool ambient air enters in tower cools down to the recirculated water for flowing through packing layer, while to ensure to blast
Air quantity cannot be excessive, cross conference and small water droplet caused to be blown out by wind from tower top, it is too small to be cooled down to recirculated water (up to not
To design requirement), the recirculated water that also ensure to flow down from packing layer cannot be flowed to from wind turbine, motor on ground, 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 of droplets impact bottom that large area continuously falls is known as the water drenching noise of but tower.Water drenching is made an uproar
The process that sound generates is that the recirculated water in cooling tower flows from top to bottom, by packing layer, then falls into the sink of cooling tower bottom
In caused by impact noise, be called water drenching noise.The volume for flowing through recirculated water, stream in water drenching noise intensity and unit interval
Amount and overboard height are relevant.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of bottom blast formula cooling tower cloth wind structures, can drop
Cooling effect is can guarantee while making an uproar again.
It can cause cooling wind wind speed disorderly uneven in existing guiding device structure, install there are certain difficulty, and
The good water conservancy diversion direction to recirculated water neither one.The bottom blast formula cooling tower cloth wind structure of the utility model can both ensure
It can only be returned in cooling tower underdrain pond by the recirculated water of packing layer rather than then flow into ground after falling on blower motor
On, while also ensure that cooling wind that bottom blasts enters inside tower body to be in direct contact with recirculated water and cooled down.
Technical solution is used by the utility model：Bottom blast formula cooling tower cloth wind structure, including being arranged on cooling
Cloth wind structure between the packing layer and air blower of tower, the cloth wind structure include upper wind plate, lower air distribution plate, gusset piece, upper cloth
Aerofoil, lower air distribution plate upper end edge gusset piece it is circumferentially equidistant be alternately arranged, upper wind plate, lower air distribution plate lower end be connected to air blast
On the ventilating duct of machine side, upper wind plate, lower air distribution plate and ventilating duct, gusset piece will be from passing through the recirculated water and drum after packing layer
The isolation such as wind turbine, motor, upper wind plate, lower air distribution plate lower end to cooling tower sidewall slope set so that recirculated water can be suitable
The upper wind plate being obliquely installed, the collecting-tank of lower air distribution plate inflow bottom of towe, plays water conservancy diversion, while upper wind plate, lower cloth
The setting of aerofoil reduces the overboard height of recirculated water, the speed of water when dropping to collecting-tank is slowed down, so as to reduce water drenching
Noise has certain interval between upper wind plate and lower air distribution plate, the cold wind that air blower bloats is made to pass through gap directly to passing through
The recirculated water of packing layer 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
Slow down it is overboard to collecting-tank when speed.
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
It is overboard to collecting-tank when speed.
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
Between plate, lower air distribution plate only there is smaller gap, recirculated water is avoided to fall on the air blower in ventilating duct, among it less than two
Side is set, and makes recirculated water that can be fallen into collecting-tank along upper wind plate, lower air distribution plate, ensure that the water conservancy diversion work to recirculated water
With.
The beneficial effects of the utility model are：
(1) structure setting of the upper and lower air distribution plate of the utility model plays guide functions to recirculated water, is returned to cooling tower
It in the collecting-tank of bottom, prevents recirculated water from falling to the mechanical, electrical machine of bottom blast, on retarder, short-circuit protection work is played to motor
With increasing the service life of motor, air blower.
(2) cooling wind that the structure setting of the upper and lower air distribution plate of the utility model can blast bottom wind turbine enters in tower,
Be in direct contact and cooled down with recirculated water, at the same air distribution plate using the good material of thermal conductivity factors such as aluminium further to recirculated water into
Row cooling improves the cooling efficiency of cooling tower.
(3) structure setting of the upper and lower air distribution plate of the utility model reduces the water drenching height of recirculated water, so as to reduce leaching
Water noise.
