Description of drawings
Fig. 1 is a structural representation of the present utility model.
The structure of the automatic fire extinguisher of the utility model fume pipeline is as shown in Figure 1: by fire and smoke exhaust valve 3, smoke discharging pipe 4, report to the police and control line 5, alarm 6, automatic alarm controller 7, magnetic valve 8, fire extinguisher 9, fire extinguisher and controller cabinet 10, gas pipeline 12, warning shower nozzle 13, fire extinguishing pipeline 14, enclosure 15, magnetic valve 16 constitutes, 1 expression induced-draft fan, 2 expression cooking fume removers, hand control valve on the 11 expression gas pipelines, wherein in the smoke discharging pipe 4 between fire and smoke exhaust valve 3 and enclosure 15 and on the enclosure 15 warning shower nozzle 13 is installed, warning shower nozzle 13, magnetic valve 8 on the fire extinguisher 9, magnetic valve 16 on the gas pipeline 12, alarm 6, fire and smoke exhaust valve 3 is connected with automatic alarm controller 7 by warning and control line 5 respectively, and fire extinguisher 9 is connected with warning shower nozzle 13 by fire extinguishing pipeline 14.
From shown in Figure 1: fire extinguisher 9 and automatic alarm controller 7 are installed in fire extinguisher and the controller cabinet 10, also can divide to be arranged.
At first, in the fume pipeline appropriate location (before entering trunk line or cooking fume filter before or smoke exhaust fan before etc. be determined on a case-by-case basis, improper burning is controlled at minimum zone as far as possible is criterion) a fire and smoke exhaust valve 3 is installed is scurried other position to prevent the intensity of a fire, one magnetic valve is installed on gas pipeline, is blocked combustion gas when meeting accident.Second installs autoamtic fire extinguishing jet head and alarm actuating contact to the fume pipeline 4 between the enclosure 15 and on the enclosure 15 before fire and smoke exhaust valve 3 (the two is combined into a device, just be the warning shower nozzle), next select extinguishing chemical and controller, the extinguishing chemical choice is bigger, use the phosphate powder extinguishing chemical in this suggestion, how many consumptions can be determined according to duct size and enclosure, its consumption of ordinary circumstance is also few (impossible oversize to the fume pipeline between the enclosure before the fire resisting damper, corresponding volume is little), so its container can be selected finished product for use, even can be directly with a tool or a few tool portable dry powder fire extinguisher, control valves etc. also can directly be selected finished product (as magnetic valve etc.) for use, controller is fairly simple, makes also optional finished product easily.With steel pipe, fire-retardant shielding line, metal hose etc. report to the police shower nozzle, alarm bell, fire and smoke exhaust valve, magnetic valve of self-extinguishing is equal to fire extinguishing container is corresponding with controller and be linked together then, like this, finished once cover fume pipeline self-extinguishing facility.The structure of this cover facility is also uncomplicated, though the design that some parts also must be concrete, general engineering technology personnel can realize commercialization in view of the above.Being exactly concrete condition according to fume pipeline in fact combines improvement with general fire extinguishing system (choosing powder extinguishing system here) and forms.It closely links together reporting to the police, prevent fires, putting out a fire and (on many fume pipelines fire resisting damper is installed also, what have also loads onto magnetic valve on gas pipeline, but not with warning and fire extinguishing organic connections, magnetic valve on the gas pipeline generally is to be surveyed, report to the police and controlled by controller by combustible gas probe, here can keep this function, increase by warning shower nozzle control function) and carry out control automatically.Below just simply introduce this facility self-extinguishing process and control procedure.
In a single day operation principle: when meeting accident, as oil cauldron when on fire then enclosure place temperature raise, when temperature is elevated to certain value, the glass marble explosion of self-extinguishing warning shower nozzle, autoamtic fire extinguishing jet head is opened under the effect of spring force, simultaneously alarm actuating contact is closed and start alarm bell by controller and sound the alarm and close fire resisting damper and smoke exhaust fan immediately, closes the solenoid valve shuts combustion gas simultaneously.The staff can take the corresponding measure fire extinguishing after hearing the police immediately, also can be by the urgent start and stop pushbutton enable of controller automatic fire extinguisher eruption fire extinguishing.Nobody the time, delaying time of controller is opened control valve on the fire extinguisher (this valve can manually and automatic), extinguishing chemical sprays self-extinguishing by shower nozzle.Arrive flue as if fire spreading between time delay, when temperature rises to certain value in the flue, (the self-extinguishing warning shower nozzle quantity that is provided with in the flue is determined on a case-by-case basis the self-extinguishing warning shower nozzle that is provided with in the flue, but must not be less than two) thus opening while alarm actuating contact control valve closed and that open immediately on the fire extinguisher by controller automatically because of the glass marble explosion equally makes the extinguishing chemical ejection realize self-extinguishing (being designed to the total flooding fire-fighting mode in the flue, so the flow of the fire extinguishing sprayer on the flow-rate ratio petticoat pipe of the fire extinguishing sprayer on the fume pipeline is wanted greatly).Between time delay if burning can stop the eruption of extinguishing chemical when controlled by the urgent start and stop button of controller.The alarm actuating contact of self-extinguishing warning shower nozzle is designed to double-contact, and controller should use dual power supply in accordance with regulations, so the reliability of facility is good.So far, we have introduced simple formation and warning automatically, fire prevention, fire extinguishing and the control procedure of above-mentioned fire-fighting equipment more clearlyly.Believe that everybody understands the fume pipeline automatic fire extinguishing technology is existing, its application and enforcement are not difficult yet.Next introduce the maintaining of facility again.
