Embodiment
As shown in Figure 1, the utility model comprises: humidity sensor, humidity control module, liquid line, gas piping and nozzle 9, humidity control module is PLC8.The initiating terminal of liquid line is provided with water pump 1, and the initiating terminal of gas piping is provided with air compressor 2, and the intersection of liquid line and gas piping is provided with nozzle 9; PLC8 is connected with humidity sensor; PLC8 is connected with the solenoid valve 7 of liquid line, gas piping respectively, when the moisture signal of humidity sensor transmission is below or above the setting value of PLC8, the solenoid valve 7 of the liquid line of PLC8, gas piping is opened or closing control, the control liquids and gases flow to intersection, finally arrive nozzle 9 and spray.Described liquid line and gas piping arrange filtration unit 4, and the filtration unit 4 of liquid line is arranged between water pump 1 and the nozzle 9; The filtration unit 4 of gas piping is arranged between air compressor 2 and the nozzle 9.One or more described humidity sensors that described liquid line and gas piping are provided with in pressure governor 6, tensimeter 5, retaining valve, solenoid valve 7, the hand valve are not less than one.The intersection of liquid line and gas piping is not less than one, and nozzle 9 is not less than one.Import hot water in the described liquid line.Described gas piping also comprises gas-holder 3, and the endpiece of air compressor 2 is connected with the inlet end of gas-holder 3.
The course of work of this example: at first open water pump 1 and air compressor 2, the state of keep that liquid line can supply water at any time, gas piping at any time can air feed.Water filters impurity through filtration unit 4, can see the numerical value of hydraulic pressure by water pressure gauge, if numerical value does not meet request for utilization, then regulates by pressure governor 6.Air filters impurity through filtration unit 4, if air pressure does not meet request for utilization, then regulates by pressure governor 6.When the moisture signal of humidity sensor transmission was lower than the setting range of PLC8, the solenoid valve 7 of the liquid line of PLC8, gas piping was opened operation, makes liquids and gases flow to intersection, finally arrived nozzle 9 and sprayed.When the moisture signal of humidity sensor transmission was higher than the setting range of PLC8, the solenoid valve 7 of the liquid line of PLC8, gas piping carried out shutoff operation, and the control liquids and gases stop to flow, and final spraying stops.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
