Description
Technical field
The utility model relates to a kind of cooling tower, relates in particular to a kind of hybrid power spraying and advances cooling tower.
Background technology
Current along with the whole society to the going deep into of energy-saving and emission-reduction, all kinds of energy-saving equipment more and more come into one's own, and are valued by everybody equally as the energy-conservation series products of the cooling tower that extensively is used.The overbottom pressure that spraying drive-in cooling tower makes full use of pipeline medium (water) just is a power, promotes blower fan running cooling medium, does not consume additional energy source, and it is relatively poor or the occasion of specific (special) requirements arranged to be specially adapted to some water quality.
Using more spray cooling tower in the market is main with reverse-flow structure; The cardinal principle of its work is: need the hot water of cooling to flow out from equipment; Because the existence of overbottom pressure; Through cooling tower bottom water inlet pipe, central tube, arrive the spraying propeller at central tube top successively, again through being connected the fog-spray nozzle ejection on the spraying propeller.Because the design of fog-spray nozzle internal structure runner has eddy flow and contraction mouth; Through the water of fog-spray nozzle ejection because the sudden enlargement of outlet; Make the current that spray be horn-like rotation water droplet and be very thin spray pattern, the water of ejection applies reaction force on fog-spray nozzle backward, makes fog-spray nozzle produce moment; The spraying propeller that promotes fog-spray nozzle and be attached thereto rotates around central shaft, and the big more rotating speed of moment is fast more.
The angle of rake rotation of spraying drives the fan blade that is installed in its bottom and rotates together, air is produced upwards flow.Upwards flow air with carry out heat exchange from the water droplet that falls, the heat transferred air in the hot water is discharged outside the tower.Discharge chassis and drip pan that the water that is cooled behind the heat falls into the bottom, be transported in the equipment, accomplish cycle period through outlet pipe.Because fan blade rotates air in the tower is discharged, and attract the tower outer air laterally to get in the tower from air inlet.After air gets in the tower, turn to upwards and flow,, absorb heat and moisture and become damp-heat air with hot water generation heat exchange.Damp-heat air is discharged outside the tower after removing the part water droplet again.
The major impetus of above-mentioned cooling tower is the kinetic energy of tower water into, so the flow of water and pressure are the significant effects factors that influence is used.That as shown in Figure 1, big when flow, when pressure head is high, the water droplet degree of atomization of fog-spray nozzle ejection is high, splash distributes is wide, be uniformly dispersed, and reaction force is big simultaneously, and the power that the spraying propeller receives is corresponding with moment also big, the angle of rake rotary speed height of spraying.The air quantity (air mass flow) that the fan blade rotation produces is also big.At this moment, full contact between air and the water droplet, exchange heat and mass exchange degree are high, and the heat that hot water is pulled away is many more, and cooling effect is good more, and cooling capacity is strong more.Otherwise when the water yield, when hydraulic pressure is low, the water atomization degree of fog-spray nozzle ejection is low, and degree of scatter is poor, the branch cloth cover is little, is prone to into columnar water and wanders down, and reaction force is also little, gives the thrust of fog-spray nozzle accordingly also little.So, the angle of rake rotary speed of spraying is just low, and the air quantity that fan blade produced (air mass flow) is corresponding also little; Air is insufficient with contacting of water droplet, and water, gas exchange abundant inadequately, and cooling effect is just poor; If the water yield is less than certain value; Will promote the propeller of spraying, will have only water spray, the situation that calm volume production is given birth to produces.
In sum, it is bigger that existing spraying advances the performance of cooling tower to receive the influence of into the tower water yield, pressure head, when the water yield, hydraulic pressure unstable; When fluctuating range is big; The fluctuating of correspondingly fluctuating of the cooling capacity of cooling tower, very unstable, thus have a strong impact on the normal use of equipment.So this type of spraying advances major defect of cooling tower to be that cooling effect is unstable, little, the water yield of particularly loading hour can't satisfy instructions for use.
