Description

Cooling tower air quantity regulating system and adopt the variable air rate cooling tower of this system
[technical field]
The utility model relates to a kind of cooling system and cooling device, cooling tower air quantity regulating system and cooling tower that especially a kind of ventilation changes with load variations.
[background technology]
Cooling tower mainly cools off as the water circulation, and in the different applicable cases of different climatic environment Various Seasonal, the inflow temperature meeting respective change of water circulation, and the requirement of leaving water temperature also has difference.
Existing cooling tower, heat exchange generally all adopt the force ventilation mode, and motor generally adopts single speed or double speed, and draught capacity is because the restriction of the fixed rotating speed of fixed frequency motor, and its ventilation value is unalterable after design is supporting.Like this, both wasted energy, do not meet environmental requirement again.Cooling tower also can shorten life cycle because of long-term load is overweight, increases maintenance cost.
Therefore, provide a kind of energy-saving and environmental protection, practical novel cooling tower system and novel cooling tower to be necessity in fact.
[summary of the invention]
The purpose of this utility model is to provide the cooling tower air quantity regulating system of a kind of energy-saving and environmental protection, practicality.
Another purpose of the present utility model is to provide a kind of energy-saving and environmental protection, practical, can reach the energy-saving cooling tower that actual conditions are regulated air quantity as required.
For realizing the utility model purpose, provide following technical scheme:
A kind of cooling tower air quantity regulating system is provided, it comprises controller, variable-frequency governor, wet bulb temperature sensor, leaving water temperature sensor and motor, the terminals of this wet bulb temperature sensor and leaving water temperature sensor are connected with the controller input, the output of this controller is connected with the input of variable-frequency governor, and the output of this variable-frequency governor connects motor.
Use the variable air rate cooling tower of above-mentioned cooling tower air quantity regulating system, it comprises tower body, and tower body inner blower and motor, and further comprise controller, variable-frequency governor, wet bulb temperature sensor, leaving water temperature sensor, the terminals of this wet bulb temperature sensor and leaving water temperature sensor are connected with the controller input, the output of this controller is connected with the input of variable-frequency governor, and the output of this variable-frequency governor connects motor, forms to survey lotus loop control loop.
Particularly, this wet bulb temperature sensor is installed in the cooling tower air intake surface, and this leaving water temperature sensor is installed on the outlet pipe of cooling tower.This system includes predefined with reference to reduced value, and these two measured data of temperature sensor are sent to controller, compare with the reference reduced value, make the judgement of air volume control then.This system can also preestablish the leaving water temperature reference value, to control leaving water temperature in preset range.
During use by the wet bulb temperature sensor that is installed in air intake surface be installed in leaving water temperature sensor on the outlet pipe, sense air intake wet-bulb temperature and leaving water temperature, and be transferred to controller by call wire, after controller is handled calculating through data, be transferred to variable-frequency governor by call wire, by variable-frequency governor according to predefined with reference to reduced value, the Based Intelligent Control that motor is quickened or slows down.
When the difference of leaving water temperature and air intake wet-bulb temperature greater than the reference reduced value of setting, and leaving water temperature according to the result of calculation of controller, goes reduce rotating speed of motor by variable-frequency governor less than when setting value, reach corresponding aeration-cooling required air quantity, thereby reach energy-conservation effect.Make cooling tower summer, daytime, when operating load was big, ventilation was corresponding big; At night, transition season, operating load hour, the corresponding minimizing of wind supply quantity.Simultaneously, ventilation changes with the variation of payload, outdoor temperature, realizes best energy-saving and noise-reducing effect.
The contrast prior art the utlity model has following advantage:
The utility model is by the contrast to cooling tower leaving water temperature and air intake wet-bulb temperature, and then the regulation and control motor speed, regulates intake in response to varying environment, season and needs, thereby reach energy-conservation effect, reduce cost, and realize best noise reduction, and easy to operate.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[specific embodiment]
See also Fig. 1, include motor 2, filler 4, water inlet pipe 5 and the outlet pipe 6 of blower fan 3, driving blower fan 3 among the figure in the tower body 1 of cooling tower, the utility model cooling tower air quantity regulating system comprises the leaving water temperature sensor 8 that is installed in outlet pipe 6, the wet bulb temperature sensor 9 that is installed in air intake surface, variable-frequency governor 7 and controller 10.
The attaching mode of variable-frequency governor 7, leaving water temperature sensor 8, wet bulb temperature sensor 9, controller 10 wherein: by the power input of external power line tipping variable-frequency governor 7, the power output end of variable-frequency governor 7 links to each other with the input terminal of motor 2 with power line; Input at variable-frequency governor 7 is connected with the output of controller 10 with power line; An input of controller 10 links to each other with the terminals of the temperature sensing controller 8 that is installed in outlet conduit 6, and another input of controller 10 links to each other with the terminals of wet bulb temperature sensor 9, forms to survey lotus loop control loop.
During use, by wet bulb temperature sensor 9 that is installed in air intake surface and temperature sensor 8, sense air intake wet-bulb temperature and leaving water temperature, and be transferred to controller 10 by call wire, after controller 10 is handled calculating through data, be transferred to variable-frequency governor 7 by call wire, by variable-frequency governor 7 according to predefined with reference to reduced value, the Based Intelligent Control that motor 2 is quickened or slows down.When the difference of leaving water temperature and air intake wet-bulb temperature greater than the reference reduced value, and leaving water temperature is when setting reference value, removes to reduce the rotating speed of motor 2 by variable-frequency governor 7, reaches corresponding aeration-cooling required air quantity, thereby reaches energy-conservation effect.Make cooling tower summer, daytime, when operating load was big, ventilation was corresponding big; At night, transition season, operating load hour, the corresponding minimizing of wind supply quantity.Simultaneously, ventilation changes with the variation of payload, outdoor temperature, realizes best energy-saving and noise-reducing effect, and easy to operate.
