Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
The present invention includes Dehumidifying element, humidifying unit and humidity detection unit; Described Dehumidifying element and described humidifying unit are in parallel or be connected in series, and described Dehumidifying element and humidifying unit are controlled by central control unit; Detecting unit comprises the first humidity sensor being positioned at humidifying unit exit, the second humidity sensor being positioned at airtight space and gas detection sensor.During described system cloud gray model, work when Dehumidifying element is different with humidifying unit.
Described Dehumidifying element comprises and is not limited to gas source generator, dehumidifier etc., and the Selective type of Dehumidifying element is different, and system pipeline connecting mode in parallel or when being connected in series is different; Described humidifying unit comprises wet-membrane humidifier, ultrasonic humidifier, centrifugation humidifier.Described gas source generator comprises gas equipment processed, gas cylinder etc., and described source of the gas comprises and is not limited to nitrogen, argon gas, air.When described system selects gas source generator, atmospheric valve is installed in airtight space gas outlet, inner installing gas detecting sensor;
Described Dehumidifying element and humidifier adopt series system to be connected, and when Dehumidifying element is gas source generator, humidifying unit and airtight space are by forming closed-loop path, and Dehumidifying element and airtight space form open loop;
Further, described Dehumidifying element and humidifier adopt series system to be connected, and when Dehumidifying element is dehumidifier, dehumidifier, humidifying unit and airtight space form closed-loop path;
Further, described Dehumidifying element and humidifier adopt parallel way to be connected, when Dehumidifying element is gas source generator, humidifying unit and airtight space form closed-loop path, the gas outlet of gas source generator and the gas outlet of humidifier are connected to the air inlet of airtight space with parallel way, and Dehumidifying element and airtight space form open loop;
Further, described Dehumidifying element and humidifier adopt parallel way to be connected, and when Dehumidifying element is dehumidifier, form closed-loop path with airtight space.
Concrete implementation step:
In central control unit, set the gas componant required for airtight space and humidity range, humidity and gas componant testing result are uploaded to central control unit and judge by detecting unit:
(1) when the second humidity sensor detects that gas componant in airtight space is not at setting range, humidity is when setting range;
Central control unit controls gas source generator and runs, and humidifying unit is not run, and the atmospheric valve be connected with airtight space is opened; Gas in airtight space is replaced away endlessly, and after the gas in airtight space is qualified, it is out of service that central control unit controls gas source generator, and humidifying unit brings into operation, and the atmospheric valve be connected with airtight space cuts out;
The detected value of central control unit according to the second humidity sensor and the difference of setting range, control humidifying unit initiation culture, and the gas in airtight space is by returning airtight space after humidifying unit humidification; Afterwards, central control unit is according to the comparative result of the detected value of the first humidity sensor and the setting value of airtight space, segmentation adjustment humidifying unit initiation culture, make the detected value of the second humidity sensor more close to the setting value of airtight space, the detected value of the first humidity sensor is more close to the detected value of the second humidity sensor;
