Abstract
The utility model relates to a gas recovery gas explosion suppressor for a pipeline. In the gas recovery gas explosion suppressor for the pipeline, a trigger starting device, a chemical medicament chamber and a sealing membrane are positioned inside a gas tank; a spray head is arranged on the top of the gas tank; and the trigger starting device is positioned inside the chemical medicament chamber, and is in electric signal connection with a controller outside the gas tank through a lead. A gas distributor is also provided; one end of the gas distributor is hemispherical; one end of the gas distributor is connected with a circular plate of which the middle part is provided with holes and the diameter is larger than that of a hemisphere; the inside of the gas distributor is hollow; a hemispherical outer wall is provided with a plurality of gas holes; and the spray head is an arc-shaped netlike spray head. In the gas recovery gas explosion suppressor, mechanical valve control is eliminated, and safe and rapid powder spray is realized by using medicament gas recovery, so that the spray delay time is shortened, the device response speed is increased, the spray efficiency is increased, and the gas explosion risk is lowered.
Description
Technical field
The utility model belongs to pipeline and uses gas explosion suppressor field, especially a kind of pipeline air-generating gas explosion suppressor.
Background technology
Existing pipeline mostly adopts storage to press 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.The mechanically controlled valve door occurs braking ineffective easily.Also there is the risk of decompression in the dry powder explosion suppressor of employing pressure storage type, and in start-up course, the friction of metal valve easily produces spark, 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
The technical problems to be solved in the utility model is, a kind of pipeline air-generating gas explosion suppressor is provided, change original storage die pressing type, the control of removal machinery valve, utilize the medicament aerogenesis to realize dusting safely and fast, shorten and spray lag time, lifting device response speed, improve spraying efficiency, reduce gas explosion harm.
The technical scheme that the utility model adopts is: a kind of pipeline air-generating gas explosion suppressor, triggering starting drive, chemical agent chamber, closure diaphragm are positioned at gas tank inside, shower nozzle is installed on the top of gas tank, and described triggering starting drive is positioned at described chemical agent chamber interior and is connected by the outer controller signal of telecommunication of wire and gas tank.
As a kind of optimal way, also have a gas distributor, an end of described gas distributor is hemispherical, and an end is connected with middle part diameter with holes greater than the plectane of half bulb diameter, and described gas distributor inner hollow has countless pores on the hemispherical outer wall.
As a kind of optimal way, described shower nozzle is the netted shower nozzle of arc.Spraying efficiency can be improved, spraying direction, the area of extinguishing chemical can be effectively controlled simultaneously.
As a kind of optimal way, flange in the bottom is arranged at described gas tank bottom, the one side of described flange in the bottom is fixed in gas tank bottom, and the plectane of another side and gas distributor is overlapping, and gas distributor inside is fixed in by the plectane mider hole of described flange in the bottom by gas distributor in described chemical agent chamber.
As a kind of optimal way, top flange is arranged at the top of described gas tank, and described closure diaphragm is between the ring flange of described top flange.
The beneficial effects of the utility model are: eliminated machinery valve control, exempted the mechanically controlled valve door and ineffective danger occurred easily braking, realized dusting safely and fast, explosion suppressor has been triggered the response time shorten to 3-10ms, spraying efficient can be up to more than 90%.

Fig. 1 is structural scheme of mechanism of the present utility model
Wherein: 1, shower nozzle, 2, top flange, 3, gas distributor, 4, trigger starting drive, 5, wire, 6, flange in the bottom, 7, the chemical agent chamber, 8, gas tank, 9, closure diaphragm.
The specific embodiment:
As shown in Figure 1: pipeline is comprised of triggering starting drive, chemical agent chamber, gas tank, closure diaphragm, shower nozzle, gas distributor, flange in the bottom, top flange with air-generating gas explosion suppressor, triggering starting drive, chemical agent chamber, closure diaphragm are positioned at gas tank inside, shower nozzle is installed on the top of gas tank, and the triggering starting drive is positioned at the chemical agent chamber interior and is connected by the controller signal of telecommunication outside wire and the gas tank.Shower nozzle is the netted shower nozzle of arc.One end of gas distributor is hemispherical, and an end is connected with middle part diameter with holes greater than the plectane of half bulb diameter, and the gas distributor inner hollow has countless pores on the hemispherical outer wall.The one side of flange in the bottom is fixed in gas tank bottom, and the plectane of another side and gas distributor is overlapping, and gas distributor inside is fixed in by the plectane mider hole of described flange in the bottom by gas distributor in the chemical agent chamber.Closure diaphragm is between the ring flange of top flange.
In when, in the gas tube emergency occuring when, survey through sensor, transmit a signal to controller, after controller is analyzed, after being confirmed to be detonator signal, controller sends the signal of telecommunication, the signal of telecommunication triggers the indoor chemical gas producing medicinal of chemical agent and produces chemical reaction, generates rapidly a large amount of gases, and instantaneous expansion becomes gases at high pressure, through behind the special distribution of gas apparatus, in the main body of explosion suppressor, form uniform and stable gases at high pressure, break through the closure diaphragm of explosion suppressor tank with pressure, thereby when pressure release, extinguishing chemical is sprayed from shower nozzle, moment forms the datonation-inhibition barrier in the pipeline, reduces temperature, eliminate flame.The netted insufflation showerhead of arc has improved spraying efficiency, can effectively control spraying direction, the area of extinguishing chemical simultaneously.
