Embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
As shown in Figs 1-4, in order to reach the purpose of the present invention, some of embodiments of device and method are saved in gas
In,
Gas is saved on device 1 and is provided with gas inlet 11, gas outlet 12 and gas sampling mouth 13, gas into
Gas port 11 is connected by air inlet tracheae with compressed air source unit 3；Gas outlet 12 is connected by outlet tracheae with gas equipment 2；Gas
Sampler body mouth 13 is connected by sampling tracheae with gas equipment 2, for being sampled to the gas in gas equipment 2.Save dress
1 is put to be connected between gas equipment 2 and compressed air source unit 3.
Gas, which saves device 1, to be included：Data input module, gas analyzer and control processor.Data input module is used
In the gas content parameter of input setting；Gas analyzer is used to gather and analyze the content of gas in gas equipment 2；At control
Reason device is connected with gas analyzer, and analysis result is sent to control processor by gas analyzer, and control processor ties analysis
Fruit is stored and processed, and handling result formation control signal is issued control valve, air inflow of the control valve to gas equipment 2
It is adjusted.In the present embodiment, control valve is arranged on outlet tracheae, and the angle that control valve is opened is bigger, gas equipment 2
Air inflow is bigger, and the angle that control valve is opened is smaller, and the air inflow of gas equipment 2 is smaller.
Control processor includes：Memory module, PID adjustment modules and display module.Memory module is used for gas equipment 2
The content of interior gas is stored；PID adjustment modules are used to be handled the analysis result of gas analyzer, and by analysis
Reason result forms control signal and issues control valve；Display module is used to carry out real-time display to the content of gas in gas equipment 2.
Gas method for saving, comprises the following steps,
(1) gas saving device 1 is connected between gas equipment 2 and compressed air source unit 3, startup power supply, gas section
Device is saved to bring into operation；

By taking SMT industries reflow oven uses nitrogen as an example, i.e., gas equipment 2 is reflow oven, and compressed air source unit 3 is nitrogen pot.It is false
If the oxygen content in product process requirements stove, within 2000ppm, if not filling gas of the present invention saves device, nitrogen can continue
It is filled with reflow oven, the oxygen content in instant stove still in equivalent consume, cause to waste well below 2000ppm, nitrogen.
This bright gas is installed between reflow oven and nitrogen pot and saves device, sets the oxygen content gas parameter required in stove, such as：
2000ppm.Gas saves device and automatically controls the oxygen content in stove in 2000ppm, does not allow oxygen content too low and causes nitrogen
Waste.
Before gas of the present invention is installed and saves device：It is 30m to consume nitrogen amount per hour3/h；
The annual nitrogen expense of brazier is：30m3/ h*8000h*0.8 members/m3=192000 yuan/year；
After gas of the present invention is installed and saves device：Nitrogen amount 22m is consumed per hour3/h-25m3/h；
The annual nitrogen expense of every reflow oven is：
22m3/ h*8000h*0.8 members/m3=140800 yuan/year；
25m3/ h*8000h*0.8 members/m3=160000 yuan/year；
Every reflow oven can save 32000 yuan to 51200 yuan RMB every year, can about save 4 yuan to 6.4 yuan per hour.
Gas saving apparatus structure of the present invention is simple, easy for installation, and gas of the present invention saving device is installed on and is set with gas
For between 2 and compressed air source unit 3, suitable for a variety of gas equipments 2 and compressed air source unit 3, have a wide range of application.Gas section

The content of gas in gas equipment 2 is observed in real time.
In order to further optimize the implementation result of the present invention, in other embodiment, remaining feature technology phase
Together, difference is, after gas is analyzed by gas sampling mouth into gas analyzer, then passes through gas outlet time
To inside gas equipment 2.The waste of gas is avoided, it is cost-effective, it is more energy efficient.Meanwhile avoid gas being directly discharged to air
In, environment is polluted, it is more environmentally friendly.
In order to further optimize the implementation result of the present invention, in other embodiment, remaining feature technology phase
Together, difference is, control processor passes through to the content of gas, the gas content parameter of setting in current gas equipment 2
And the slope of the change curve of gas content is handled in gas equipment 2, handling result is obtained, and forms control signal hair
Give control valve；
If the slope of the change curve of gas content is just in gas equipment 2, in current gas equipment 2 content of gas with
The gas content parameter of setting difference also for just, illustrate, illustrates the content of gas in current gas equipment 2 higher than setting
Gas content parameter, and there is ascendant trend, then send first control signal and directly closed to control valve, control valve, fast prompt drop
The content of gas in low gas equipment 2；
If the slope of the change curve of gas content is negative in gas equipment 2, in current gas equipment 2 content of gas with
The gas content parameter of setting difference also for just, illustrate that the content of gas in current gas equipment 2 contains higher than the gas of setting
Parameter is measured, but there is downward trend, then sends second control signal to control valve, the angle that control valve is opened reduces, slowly drop
The content of gas in low gas equipment 2；
If the slope of the change curve of gas content is just in gas equipment 2, in current gas equipment 2 content of gas with
The gas content parameter of setting difference be also negative, illustrate that the content of gas in current gas equipment 2 contains less than the gas of setting
Parameter is measured, but there is ascendant trend, then sends the 3rd control signal to control valve, the angle increase that control valve is opened, slowly increases
Add the content of gas in gas equipment 2；
If the slope of the change curve of gas content is negative in gas equipment 2, in current gas equipment 2 content of gas with
The gas content parameter of setting difference be also negative, illustrate that the content of gas in current gas equipment 2 contains less than the gas of setting
Parameter is measured, and there is downward trend, then sends the 4th control signal to control valve, control valve is directly opened to maximum angle, soon
The content of gas in speed increase gas equipment 2.
Control processor is by the gas content parameter to the content of gas in current gas equipment 2, setting and uses gas
The slope of the change curve of gas content is handled in equipment 2, and it is more thorough to consider, more energy efficient and environmentally friendly, makes in gas equipment 2
Gas content gentle transition will not rise sharply the phenomenon of rapid drawdown.
New preferred embodiment, it is noted that for those of ordinary skill in the art, do not departing from this hair
On the premise of bright creation design, various modifications and improvements can be made, these belong to protection scope of the present invention.
