Accompanying drawing explanation
Fig. 1 is refuse landfill gas engine health protective device system block diagram.
In figure: 1, gas driven generator group safety guard; 2, gas engine cylinder temperature safety guard; 3, processing module; 4, detonation sensor; 5, biogas leak sensor; 6, flame sensor; 7, smoke-detecting sensor; 8,1 cylinder cylinder temperature sensor; 9, n cylinder cylinder temperature sensor; 10, power management control; 11, circuit breaker; 12, ACV Air Cut Valve; 13, arresting gear; 14, rubbish landfill gas engine monitoring device; 15, refuse landfill gas generating set far-end computer supervising device; 16, refuse landfill gas engine health protective device.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, carry out clear, complete description to the technical scheme in the utility model embodiment, described embodiment is only the utility model part embodiment, instead of whole embodiments.
A kind of refuse landfill gas engine health protective device; safety guard is configured with Boolean value output sensor signaling interface, programming instruction interface, drived control interface, completes the control of rotating speed, pressure, the signals collecting of temperature and arresting gear, ACV Air Cut Valve.
Wherein, gas engine cylinder temperature safety guard can complete the collection of single cylinder temperature, average cylinder temperature, single-row cylinder temperature; carry out reservation normal data, data processing operation of fixing a breakdown; by the Treatment Analysis to cylinder temperature; according to different operating mode, provide power management control, circuit breaker, ACV Air Cut Valve work.Main protection function, by safety guard complete independently, opens backup protection functional realiey redundancy protecting when inefficacy appears in safety guard by basic supervising device automatically.Improve the reliability of safety protection function, in design, in sensor type, line fault, processor fault, communication failure etc., take certain measure.Safety guard works alone, security data by internal bus communication to basic supervising device, shown by parameter display screen display and externally communication to far-end computer device.
Described accompanying drawing 1 is refuse landfill gas engine monitoring equipment safety protective device system block diagram.Carry out safeguard protection to gas engine, the method mainly used has two kinds.
In described accompanying drawing 1, method 1 is when gas driven generator group safety guard monitors the alarm signal that detonation sensor sends, and cuts off gas preliminary treatment main line and also makes gas engine emergency shutdown;
In described accompanying drawing 1, method 1 is for sending alarm signal when gas driven generator group safety guard monitors biogas leak sensor, cuts off gas preliminary treatment main line and makes gas engine emergency shutdown;
In described accompanying drawing 1, method 1 is for sending alarm signal when gas driven generator group safety guard monitors flame sensor, cuts off gas preliminary treatment main line and makes gas engine emergency shutdown;
In described accompanying drawing 1, method 1 is for sending alarm signal when gas driven generator group safety guard monitors smoke-detecting sensor, cuts off gas preliminary treatment main line and makes gas engine emergency shutdown;
In described accompanying drawing 1, method 2 is for when gas engine cylinder temperature safety guard monitoring unit single cylinder row Wen Wendu is greater than 690 DEG C, and supervising device protection judgement sends sound and light alarm and after delay judgement confirmation, closes flow valve protection and shut down;
In described accompanying drawing 1, method 2 is for doing work when the several cylinder excess load of gas engine cylinder temperature safety guard gas engine; cylinder Wen Wendu raises; monitoring unit single cylinder row Wen Wendu is less than 690 DEG C; during cylinder temperature image data mistake; can take fault-tolerant processing in cylinder temperature safety guard inside, Cylinder simultaneous faults cylinder temperature data of will reporting to the police will not participate in the computing of average cylinder temperature value.When unit A arrange, B itemize column average cylinder Wen Wendu be greater than 660 DEG C time, supervising device protection judgement send sound and light alarm and delay judgement confirm after, close flow valve protection shut down;
In described accompanying drawing 1, method 2 is for monitoring the acting of gas engine cylinder excess load when gas engine cylinder temperature safety guard; cylinder Wen Wendu raises; when unit single cylinder row Wen Wendu and this column average exhaust temperature difference absolute value (comprise 200 DEG C) more than 200 DEG C; during cylinder temperature image data mistake; can take fault-tolerant processing in cylinder temperature safety guard inside, Cylinder simultaneous faults cylinder temperature data of will reporting to the police will not participate in the computing of average cylinder temperature value.Judgement system sound and light alarm protected by supervising device and delay judgement confirms that closing flow valve protection shuts down;
The power control signal that power management control receiver gases generating set safety guard in described accompanying drawing 1 and gas engine cylinder temperature safety guard send also controls to reduce power by processing module automatically.
Automatically will cut off load break switch by processing module after circuit breaker receiver gases generating set safety guard in described accompanying drawing 1 and gas engine cylinder temperature safety guard send sub-gate signal, protect peripheral power consumption equipment;
ACV Air Cut Valve receiver gases generating set safety guard in described accompanying drawing 1 and gas engine cylinder temperature safety guard send emergency-stop signal and can automatically control emergency shutdown ACV Air Cut Valve action cut-out air inlet pipeline by processing module and make gas engine emergency shutdown.
