Specific embodiment
Specific embodiment one: with reference to Fig. 1, Fig. 2, present embodiment is described, the biogas fermentation engineering of present embodiment is online
Monitor and alarm system includes biogas production Factory Building 1, enters gas blower fan 2, blower fan 3 of giving vent to anger, methane detector 4, ammonia detector 5, sulfur
Change hydrogen detector 6, warning lamp 8, buzzer 9 and liquid crystal display screen 10, the left side body of wall centre position in described biogas production Factory Building 1
It is provided with into gas blower fan 2, the described top and bottom entering gas blower fan 2 are respectively arranged with blower fan 3 of giving vent to anger, described CH_4 detection
Instrument 4, ammonia detector 5 and human inductor 7 are arranged on the roof portion of biogas production Factory Building 1, and described H2S detector 6 is pacified
It is contained in the room bottom of biogas production Factory Building 1, door 11 upper end of described biogas production Factory Building 1 is separately installed with warning lamp 8, honeybee
Ring device 9 and liquid crystal display screen 10, described biogas fermentation engineering online monitoring alarm system also includes dsp controller 12, described first
Alkane detector 4, ammonia detector 5, H2S detector 6 are connected with the signal input part of dsp controller 12, dsp controller 12
Output control terminal be connected with entering gas blower fan 2, blower fan 3 of giving vent to anger, warning lamp 8, buzzer 9 and liquid crystal display screen 10 and setting up respectively；Described
The signal input part of dsp controller 12 be connected with human inductor 7, dsp controller 12 control output end be connected with
Too net transmitter 13；Described is arranged on the H2S detector 6 of biogas production Factory Building 1 room bottom apart from ground 15cm；Described
Gas blower fan 2 and blower fan 3 of giving vent to anger pass through controller of fan 14 and be connected with dsp controller 12 foundation.It is arranged such, when generation biogas
During leakage, the molecular mass of methane and ammonia is little, can be suspended in air top layer, and hydrogen sulfide molecule quality is big, and sink-float is at air bottom
Layer, therefore methane detector 4 and ammonia detector 5 are arranged on the top of biogas production Factory Building 1 using ceiling；H2S detector
5 install at the 15cm of ground, are so conducive to improving the accuracy of in the air gas content detection.
Specific embodiment two: with reference to Fig. 1, Fig. 2, present embodiment is described, the biogas fermentation engineering of present embodiment is online
What the upper end entering gas blower fan 2 described in monitor and alarm system set give vent to anger blower fan 3 apart from biogas production factory roof distance as
10cm, what the described lower end entering gas blower fan 2 set give vent to anger blower fan 3 apart from biogas production facility floor distance as 10cm；So
Setting, the gas blower fan 2 that enters realizing ventilatory is installed in the centre position of room height, and blower fan 3 of giving vent to anger is respectively away from roof and ground
Install at the 10cm of face, be easy to the air-out of house interior, during biogas leakage, methane and ammonia are suspended in air top layer, sulfuration
Hydrogen rises and falls in air bottom, is now arranged on biogas production Factory Building 1 top and the blower fan 3 of giving vent to anger of bottom can achieve gas leakage
Diffusion is discharged.
The present invention is to design a kind of marsh gas fermentation processes monitoring and early warning system with digital signal processor dsp for control core
System.Dsp has the higher speed of service and abundant peripheral module, disclosure satisfy that quick detection and warning function.Outside setting
Methane, ammonia, the analogue signal of H2S detector collection input to the analog interface of dsp, are sentenced by dsp internal processes
Disconnected.And the gas content collecting result is shown on liquid crystal display outdoors.
Alarm to the leak case of biogas is divided into two kinds of situation one-level levels to report to the police: methane content > 1%, ammonia level >
50ppm, hydrogen sulfide content > 1ppm, secondary alarm: methane content > 4%, ammonia level > 300ppm, hydrogen sulfide content > 10ppm,
One-level is reported to the police when occurring, and shows there is indication of leakage or preliminary leakage, warning lamp 8 can light, and causes attendant's
Note, ventilation inlet air blower fan opened by controller and air-out blower fan is taken a breath, and now attendant can enter according to practical situation
Enter interior to carry out looking into repairing, the expansion further of Accident prevention, if now human inductor 7 can't detect live someone, control
Device then can send alarm signal by Ethernet to director's mobile phone, reports accident conditions.
When secondary alarm occurs, show that leak case is serious, easily cause blast and intoxication accident, buzzer sends police
Report, points out operator to withdraw as early as possible.Controller automatically cuts off the electrical source of power of biogas production, and blower fan proceeds to take a breath.As
Now human inductor can't detect live someone to fruit, and controller then can send alarm signal by Ethernet to director's mobile phone
Number, report accident conditions.
After accident is processed, blower fan, warning lamp and buzzer stop alarm and stop, and recover normal monitoring state.
