Abstract
The utility model relates to an automatic gas explosion suppression device for a pipeline, which comprises a controller. The controller is connected with an ultraviolet flame sensor by a sensor input interface; the output end of the controller is connected with an explosion suppressor by a gas generator; the controller is also provided with an online interface and a monitoring interface; and the power supply end of the controller is connected with a DC (Direct Current) stabilized voltage supply. Detection is carried out by the ultraviolet flame sensor, a signal is sent to the controller, the control signal is sent to the gas generator by the controller, the gas generator pushes a push valve body to start the explosion suppressor to rapidly discharge a great volume of gas and a sealing diaphragm of an explosion suppressor tank is broken through by the pressure, so that dry powder is sprayed out of a spray nozzle in the pressure relief process and the fire extinguishing aim is achieved. According to the utility model, gas production controlled by agent is eliminated, safe and rapid powder spraying is implemented by utilizing compressed gas, spraying delay time is shortened, the response speed of the device is promoted, spraying efficiency is improved and the gas explosion hazard is reduced.
Description
Technical field
The utility model belongs to pipeline with gas explosion suppressor field, relates in particular to a kind of pipeline with automatic gas explosion suppression device.
Background technology
Existing pipeline mostly adopts the aerogenesis spray regime with the gas explosion suppressor, ejects the powder extinguishing agent that explosion suppressor stores, and it is inhomogeneous that gas appears in air-generating easily, brakes ineffective.Also there is the risk of decompression in the dry powder explosion suppressor of employing air-generating, and in start-up course, chemical agent produces a large amount of heat, easily lights methane gas, produces blast.And spraying efficiency is low, and the response time is long, and is most of between 20～100ms.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of pipeline with automatic gas explosion suppression device, change original aerogenesis pattern, remove by chemical aerogenesis control, utilize compressed gas to realize dusting safely and fast, shorten and spray lag time, lifting device response speed, improve spraying efficiency, reduce gas explosion harm.
To achieve these goals, the technical solution adopted in the utility model is: a kind of pipeline is with automatic gas explosion suppression device, include controller, controller links to each other with ultraviolet flame sensor by the sensor input interface, the output of controller links to each other with explosion suppressor by gas generator, controller also is provided with on-line interface and monitor-interface, and the power end of controller links to each other with D.C. regulated power supply.
Described on-line interface is used for connecting a plurality of explosion suppressors, receives a plurality of signals.
Described monitor-interface is used for real-time monitoring equipment ruuning situation.
Ultraviolet flame sensor inputs to controller with signal, controller is transferred to gas generator after signal is handled, and gas generator blast pusher moving valve impels compressed air to promote the rapider unlatching of valve body, make gas promote dry powder and overflow, play the effect of rapid fire extinguishing.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is owing to adopted controller that the signal that ultraviolet flame sensor obtains is handled, and by controller with the control signal gas generator, gas generator promotes valve body and opens explosion suppressor, eliminated by chemical aerogenesis control, it is inhomogeneous to occur gas easily, brakes ineffective phenomenon.Utilize compressed gas to realize dusting safely and fast, shorten and spray lag time, the lifting device response speed improves spraying efficiency, reduces gas explosion harm.Realize dusting safely and fast, explosion suppressor is triggered the response time shorten to 1-5ms, spraying efficient can be up to more than 95%.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Among the figure: 1-D.C. regulated power supply, 2-ultraviolet flame sensor, 3-controller, 4-on-line interface, 5-monitor-interface, 6-explosion suppressor, 7-gas generator.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1, a kind of pipeline is with automatic gas explosion suppression device, include controller 3, controller 3 links to each other with ultraviolet flame sensor 2 by the sensor input interface, the output of controller 3 links to each other with explosion suppressor 6, controller 3 also is provided with on-line interface 4 and monitor-interface 5, and the power end of controller 3 links to each other with D.C. regulated power supply 1.
Described on-line interface 4 is used for connecting a plurality of explosion suppressors, receives a plurality of signals.
Described monitor-interface 5 is used for real-time monitoring equipment ruuning situation.
In when, in the gas tube emergency taking place when, survey through ultraviolet flame sensor 2, transmit a signal to controller, and by controller control signal is transmitted on the gas generator, gas generator promotes valve body and opens the explosion suppressor opening device, emits a large amount of gases rapidly, make pressure break through the diaphragm that seals of explosion suppressor jar, thereby when pressure release dry powder is sprayed from shower nozzle, moment forms the datonation-inhibition barrier in the pipeline, reduces temperature, eliminates flame.The netted insufflation showerhead of arc has improved spraying efficiency, can effectively control spraying direction, the area of extinguishing chemical simultaneously.
