Description
Technical field
This utility model belongs to tunnel ventilation energy-conserving control technology field, especially relevant with a kind of Tunnel Ventilation System.
Background technology
Along with China's highway development, expressway construction constantly extends to mountain area, and freeway tunnel is more and more, more and more longer.Owing to tunnel is the region of a relative closure, the waste gas discharged when automobile travels wherein is unlike being diffused in air with natural wind and traffic air when other sections.Especially for distance, tunnel that the volume of traffic is big, natural wind and traffic air are poor to the diadochy of air in tunnel, cause the harmful substances such as carbon monoxide, oxynitride, Hydrocarbon, sulphurous acid gas and smog dust that automobile discharges can cause the pollution of air in tunnel.When CO mass concentration is the biggest, the health of entail dangers to people；Smog dust then can deteriorate the visual field, and impact is driven the sight line making personnel, brought potential safety hazard to driving.For solving the ventilating problem in tunnel, in tunnel, generally it is provided with Tunnel Ventilation System, though existing tunnel ventilating system can play draught effect, but blower fan is directly by controller control, blower fan frequent start-stop, after fan starting, its wind speed can not carry out speed governing according to the quality of the air quality in tunnel, consumes energy bigger.
Utility model content
After the purpose of this utility model is intended to overcome the fan starting of existing tunnel ventilating system, its wind speed can not regulate, and consume energy bigger defect, it is provided that a kind of can regulate blower fan wind speed and energy-conservation Tunnel Ventilation System.
nullFor this，This utility model is by the following technical solutions: a kind of Tunnel Ventilation System，It is characterized in that，Described ventilating system includes import blower fan electric control box、Outlet blower fan electric control box、Blower fan、CO sensor、Traffic flow detector and console，It is fitted with a controller and several converters in import blower fan electric control box and outlet blower fan electric control box，All converters are controlled by described controller，Each converter correspondence connects a described blower fan，Blower fan is by converter VFC，Each blower fan carries out the detection of CO concentration by corresponding described CO sensor，And the information detected is fed back to controller，Controller controls corresponding converter frequency conversion according to the difference of feedback information，Thus realize the change of corresponding blower fan wind speed，Controller in import blower fan electric control box and outlet blower fan electric control box is all connected with described traffic flow detector，The information of vehicle flowrate detected is fed back simultaneously feeds by traffic flow detector、Controller in outlet blower fan electric control box，Controller in the controller of import blower fan electric control box and outlet blower fan electric control box is connected by Ethernet，Two controllers are all connected with described console and are monitored in real time by console.
When this utility model uses, import blower fan electric control box is positioned at tunnel entrance, outlet blower fan electric control box is positioned at tunnel exit, how many controllers of two electric control boxes controls the wind speed of all blower fans according to the car amount that traffic flow detector detects, difference further according to the CO concentration detected by different CO sensors, realize, by converter, the wind speed that different blower fan is different, and the transformation of wind speed can be carried out according to the change of periphery CO concentration, reduce the power consumption of each blower fan.
This utility model can reach following beneficial effect: 1, each blower fan is by a converter VFC, can control the wind speed of each blower fan at any time, reach efficient, energy-conservation purpose, complies with the trend that national energy-saving reduces discharging；2, each blower fan carries out the detection of CO concentration, then the wind speed by the corresponding corresponding blower fan of converter VFC by a corresponding CO sensor, so can extend the service life of blower fan with the ventilation in effective guarantee tunnel simultaneously.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
nullAs shown in Figure 1，This utility model includes import blower fan electric control box、Outlet blower fan electric control box、Blower fan、CO sensor、Traffic flow detector and console，It is fitted with a controller and several converters in import blower fan electric control box and outlet blower fan electric control box，All converters are controlled by described controller，Each converter correspondence connects a described blower fan，Blower fan is by converter VFC，Each blower fan carries out the detection of CO concentration by corresponding described CO sensor，And the information detected is fed back to controller，Controller controls corresponding converter frequency conversion according to the difference of feedback information，Thus realize the change of corresponding blower fan wind speed，Controller in import blower fan electric control box and outlet blower fan electric control box is all connected with described traffic flow detector，The information of vehicle flowrate detected is fed back simultaneously feeds by traffic flow detector、Controller in outlet blower fan electric control box，Controller in the controller of import blower fan electric control box and outlet blower fan electric control box is connected by Ethernet，Two controllers are all connected with described console and are monitored in real time by console.
When this utility model uses, import blower fan electric control box is positioned at tunnel entrance, outlet blower fan electric control box is positioned at tunnel exit, how many controllers of two electric control boxes controls the wind speed of all blower fans according to the car amount that traffic flow detector detects, difference further according to the CO concentration detected by different CO sensors, realize, by converter, the wind speed that different blower fan is different, and the transformation of wind speed can be carried out according to the change of periphery CO concentration, reduce the power consumption of each blower fan.
