Specific embodiment
Specific embodiment one:Present embodiment is illustrated with reference to Fig. 1, Fig. 2, the biogas fermentation engineering of present embodiment is online Monitor and alarm system includes biogas production factory building 1, enters gas blower fan 2, outlet blower fan 3, methane detector 4, ammonia detector 5, sulphur Change hydrogen detector 6, warning lamp 8, buzzer 9 and liquid crystal display 10, the left side wall centre position in described biogas production factory building 1 It is provided with into gas blower fan 2, the described top and bottom for entering gas blower fan 2 are respectively arranged with outlet blower fan 3, 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 Mounted in the room bottom of biogas production factory building 1, the upper end of door 11 of described biogas production factory building 1 is separately installed with warning lamp 8, honeybee Ring device 9 and liquid crystal display 10, described biogas fermentation engineering online monitoring alarm system also include 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 with enter gas blower fan 2, outlet blower fan 3, warning lamp 8, buzzer 9 and liquid crystal display 10 and set up respectively to be connected;It is 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;The described H2S detector 6 installed in the room bottom of biogas production factory building 1 is apart from ground 15cm;It is described Gas blower fan 2 and outlet blower fan 3 be connected by the foundation of controller of fan 14 and dsp controller 12.It is arranged such, when generation biogas During leakage, the molecular mass of methane and ammonia is small, can be suspended in air top layer, and hydrogen sulfide molecule quality is big, rises and falls 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 degree of accuracy of gas content detection in air.
Specific embodiment two:Present embodiment is illustrated with reference to Fig. 1, Fig. 2, the biogas fermentation engineering of present embodiment is online The outlet blower fan 3 that the upper end for entering gas blower fan 2 described in monitor and alarm system sets apart from biogas production factory roof distance as 10cm, the outlet blower fan 3 that the described lower end for entering gas blower fan 2 sets is 10cm apart from the distance of biogas production facility floor;So Set, realize that the gas blower fan 2 that enters of ventilatory is installed in the centre position of room height, outlet blower fan 3 is respectively away from roof and ground Installed at the 10cm of face, be easy to the air-out of house interior, when biogas are leaked, methane and ammonia are suspended in air top layer, vulcanization Hydrogen sink-float can realize gas leakage in air bottom, the outlet blower fan 3 for being now arranged on the top and bottom of biogas production factory building 1 Diffusion discharge.
The present invention is to design a kind of marsh gas fermentation processes monitoring and early warning system by control core of digital signal processor DSP System.DSP has the speed of service higher and abundant peripheral module, disclosure satisfy that quick detection and warning function.What outside was set Methane, ammonia, the analog signal of H2S detector collection are input into the analog interface of DSP, are sentenced by DSP internal processes It is disconnected.And the gas content result that will be collected is included on liquid crystal display outdoors.
Alarm to the leak case of biogas is divided into two kinds of situation one-level level alarms:Methane content>1%, ammonia level> 50ppm, hydrogen sulfide content>1ppm, secondary alarm:Methane content>4%, ammonia level>300ppm, hydrogen sulfide content>10ppm,
When one-level alarm occurs, show there is indication of leakage or preliminary leakage, warning lamp 8 can be lighted, and cause attendant's Note, controller opens ventilation inlet air blower fan and air-out blower fan is taken a breath, and now attendant can enter according to actual conditions Entering interior look into repairing, and prevents the further expansion of accident, if now human inductor 7 can't detect live someone, control Device then can send alarm signal by Ethernet to director's mobile phone, report accident conditions.
When secondary alarm occurs, show that leak case is serious, easily trigger blast and intoxication accident, buzzer sends police Report, points out operating personnel to withdraw as early as possible.Controller automatically cuts off the electrical source of power of biogas production, and blower fan proceeds ventilation.Such 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.
Present embodiment is the exemplary illustration to this patent, does not limit its protection domain, people in the art Member can also be changed to its part, as long as no the Spirit Essence beyond this patent, all in the protection domain of this patent.
