Abstract
The utility model relates to a gas-storage type gas explosion suppressor for a pipeline, which comprises a high pressure gas bottle, a starting valve, a powder barrel and the like. A spray nozzle is arranged at the top of the powder barrel; the trigger starting valve is positioned between the high pressure gas bottle and the powder barrel; a valve body is started by a gas generator and gas in a gas storage tank is sprayed out to push dry powder in the powder barrel to outflow so as to achieve a fire extinguishing effect; and the spray nozzle is an arch net-shaped spray nozzle. According to the utility model, agent gas production control 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 air storing type gas explosion suppressor.
Background technology
Existing pipeline mostly adopts the aerogenesis spray regime with the gas explosion suppressor, the powder extinguishing agent that explosion suppressor stores, through controller control, the startup by-pass valve control ejects powder extinguishing agent automatically, with burn or the detonation propagation process in flame put out.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 is to provide a kind of pipeline air storing type gas explosion suppressor, 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 air storing type gas explosion suppressor; include air accumulator; the air accumulator lower end is provided with containment vessel, and the containment vessel front end is provided with adpting flange, is provided with valve body in containment vessel; valve body is connected with the powder bucket; powder bucket top is provided with mounting flange, and adpting flange is connected with mounting flange, and the bottom of powder bucket is provided with nozzle.
The refitting nitrogen pressure is 2Mpa to 5Mpa in the described air accumulator; The start-up time of air accumulator is less than 55ms.
Described side of valve body is provided with pressure switch and filling valve.
The inside of described valve body is provided with spool, and spool links to each other with gas generator, and gas generator receives extraneous signal and opens.
Described nozzle is the netted shower nozzle of arc.
Heavy filling amount is 6kg to 40kg in the described powder bucket.
Be transferred to valve body by signal, valve body starts automatically by inner, impels the rapider unlatching of valve body inner spool, and valve body is opened air accumulator by the thrust of gas generator and the thrust of Compressed Gas, the dry powder that makes gas in the air accumulator promote in the powder bucket overflows, and plays the effect of rapid fire extinguishing.
The beneficial effects of the utility model are: 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.Nozzle is the netted shower nozzle of arc, can improve spraying efficiency, can effectively control spraying direction, the area of extinguishing chemical simultaneously.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%.

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 accompanying drawing 1, pipeline is made up of air accumulator 1, connection valve 2, valve body 3, pressure switch 4, mounting flange 5, nozzle 6, powder bucket 7, adpting flange 8 and filling valve 9 with air storing type gas explosion suppressor.Air accumulator 1 lower end is provided with and connects valve 2, connects valve 2 front ends and is provided with adpting flange 8, is provided with valve body 3 in connecting valve 2, valve body 3 is connected with powder bucket 7, powder bucket 7 tops are provided with mounting flange 5, and adpting flange 8 is connected with mounting flange 5, and the bottom of powder bucket 7 is provided with nozzle 6.
The refitting nitrogen pressure is 2Mpa to 5Mpa in the described air accumulator 1; The start-up time of air accumulator 1 is less than 55ms.
The side of described valve body 3 is provided with pressure switch 4 and filling valve 9.
The inside of described valve body 3 is provided with spool, and spool links to each other with gas generator, and gas generator receives extraneous signal and opens.
Described nozzle 6 is the netted shower nozzle of arc.
Heavy filling amount is 6kg to 40kg in the described powder bucket 7.
In when, in the gas tube emergency taking place when, survey through sensor, transmit a signal to gas generator, gas generator is opened rapidly after receiving signal, promotes valve body 3 and opens, and 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 nozzle 6, moment forms the datonation-inhibition barrier in the pipeline, reduces temperature, eliminates flame.The netted spreader nozzle 6 of arc has improved spraying efficiency, can effectively control spraying direction, the area of extinguishing chemical simultaneously.
