As shown in Figs. 1-2, the cooling tower of a kind of band joint fog dispersal exhaust system, the cooling tower include tower body 1, combine and disappear
Mist exhaust system 2 and PLC controller 3, the joint fog dispersal exhaust system 2 are connect with tower body 1, the control of PCL controller 3 connection
Fog dispersal exhaust system 2 is closed, the joint fog dispersal exhaust system 2 includes hot-air main air blower 21, cold air pair blower 22, cold and hot sky
Gas mixed flow case 23, wind guiding tube 24, temperature sensor 25, humidity sensor 26, the hot-air main air blower 21 and cooling tower tower body 1
Top connects, and connects at the top of the hot and cold air mixed flow case 23 and hot-air main air blower 21, and the cold air pair blower 22 is arranged
Other than 23 both ends of hot and cold air mixed flow case, the wind guiding tube 24 is arranged other than 23 two sides of cold air mixed flow case, the temperature
Sensor 25 is arranged on tower body 1, and the setting of humidity sensor 26 is other than 23 top of hot and cold air mixed flow case.
The wind guiding tube 24 is arcuate structure, and 24 air outlet of wind guiding tube is downward.
There are four the wind guiding tubes 24.
The working method of the joint fog dispersal exhaust system 2 is as follows:
1) temperature sensor 25 incudes ambient temperature, PCL controller 3 is sent by ambient temperature value, when outer
When boundary's temperature is higher than 0 DEG C, joint fog dispersal exhaust system 2 is controlled by PLC controller 3, hot-air main air blower 21 is opened, closes cold
Air pair blower 22, the damp-heat air generated in cooling tower through hot-air main air blower 21 flow to hot and cold air mixed flow case 23 and by drawing
Air duct 24 is discharged；
2) temperature sensor 25 incudes ambient temperature, and humidity sensor 26 incudes humidity in cooling tower, and will be extraneous
Humidity value is sent to PCL controller 3 in ambient temperature value and cooling tower, and when ambient temperature is lower than 0 DEG C, humidity is less than in cooling tower
When 80%, joint fog dispersal exhaust system 2 is controlled by PLC controller 3, cold air pair blower 22 is opened, closes the main wind of hot-air
Machine 21, the interior damp-heat air generated of cooling tower are discharged after entering hot and cold air mixed flow case 23 by cold air pair blower 22；

Humidity value is sent to PCL controller 3 in ambient temperature value and cooling tower, and when ambient temperature is lower than 0 DEG C, humidity is greater than in cooling tower
When 80%, joint fog dispersal exhaust system 2 is controlled by PLC controller 3, opens hot-air main air blower 21 and cold air pair blower
22, and cold air pair blower 22 is set as inverting, hot-air main air blower 21 extracts damp-heat air that cooling tower generates to cold and hot
Air mixed flow case 23, cold air pair blower 22 extract extraneous cold dry air to hot and cold air mixed flow case 23, and mixed gas is again
It is discharged through wind guiding tube 24；
4) above 1) -3 are repeated) work.
Working principle of the present invention is as follows:
Steam fogging hoarfrost point is 0 DEG C of temperature, humidity 100%, when ambient temperature is higher than 0 DEG C, in cooling tower
Damp-heat air need to be discharged after the cooling of overfire air main air blower 21, and discharge will not generate white haze phenomenon at this time；When external environment temperature
Degree is lower than 0 DEG C, when the humidity of damp-heat air is less than 80% in cooling tower, is also not up to the degree of fogging frosting at this time, and because outer
Boundary's environment temperature is lower, it is only necessary to which opening cold air pair blower 22, the damp-heat air in cooling tower can be discharged (if opening at this time
Hot-air main air blower 21 is then more wasteful)；When ambient temperature ambient temperature, it is lower than 0 DEG C, damp-heat air is wet in cooling tower
When degree is greater than 80%, when the humidity of damp-heat air is bigger, steam easily reaches fogging hoarfrost point, and hot-air main air blower 21 is opened at this time
It opens, cold air pair blower 22 is opened and inverted, and the cold dry air of damp-heat air and external environment that cooling tower generates is mixed
Stream will not produce so as to which the humidity of damp-heat air in cooling tower is reduced to 80% when hereinafter, being discharged in turn from wind guiding tube 24
Raw white haze phenomenon.
The open and close of hot-air main air blower 21, cold air pair blower 22 of the invention mainly pass through PLC controller 3 with
The electric appliance connection of the joint fog dispersal exhaust system 2 of cooling tower, electric signal is transmitted to PLC by temperature sensor 25 and humidity sensor 26
After controller 3, PLC controller 3 converts the electrical signal to the mechanical signal of hot-air main air blower 21, cold air pair blower 22 again,
To realize hot-air main air blower 21, the switch of cold air pair blower 22 and closure.
Cooling tower of the invention controls joint fog dispersal air draft system with joint fog dispersal exhaust system 2, by PLC controller 3
The operation of system 2 in tower in the biggish situation of damp-heat air humidity, is led to even if ambient temperature is lower on the one hand in cold winter
The phenomenon that collective effect of overfire air main air blower 21 and cold air pair blower 22 can also generate white haze to avoid cooling tower, operation
More environmentally friendly, on the other hand, ambient temperature is lower, in the case that damp-heat air humidity is little in tower, opens cold air pair blower 22
Air draft, energy conservation and environmental protection；Wind guiding tube 24 is the gas row that arcuate structure and air outlet are more advantageous to downwards cooling tower generation
Out.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining specific principle of the invention and its actually answering
With so that those skilled in the art can be realized and utilize a variety of different exemplary implementation schemes of the invention and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
