Description
Technical field
The utility model relates to organic exhaust gas, the environment-friendly engineering of combustible dust system pipeline, safety engineering field, particularly relates to a kind of explosion proof and suppression device for dust pelletizing system.
Background technology
In conveying or processing procedure, when because of incendiary source, there is detonation, and then blast or detonation, the generation caused the accident in organic exhaust gas.Also some organic exhaust gas is that burning mode processes, and under fortuitous event, tempering may occur, and then cause explosion accident.Dust gathering and flying upward in dust pelletizing system is very easily within the scope of dust explosion, thus runs into thermal source (naked light or temperature) and burn, and then detonation, blast or detonation accident occur.
Domestic and international to organic exhaust gas conveying or treatment system at present, and can mainly concentrate on temperature-sensitive to flammable medium, photosensitive or feel cigarette and interlock containing the field that the dust prevention system of combustible dust study, and then valve-off, or take the measures such as fire resisting damper, and pipeline datonation-inhibition, isolation or venting of dust explosion measure.But because these measures all can not stop detonation or blast impulse wave propagation, or effectively cannot stop the destruction of detonation or explosion wave, and then have an accident.And during accident, detonation or explosion wave are all along pipe transmmision to factory building or workshop, and then cause subsequent explosion generation casualties or property loss accident.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of explosion proof and suppression device for dust pelletizing system, the effect of explosion arrestment back-fire relief is realized by adopting specific physical arrangement, effective prevention relates in organic exhaust gas, combustible dust system the propagation of shock wave in pipeline when there is detonation or explosion, and then the generation of prevention accident, simultaneously, datonation-inhibition and extinguishing chemical is provided with in device of blast prevention, and then reach explosion arrestment and fire extinguishing double action, there are market prospects widely popularizing of the explosion proof and suppression device for dust pelletizing system.
For solving the problems of the technologies described above, the utility model provides a kind of explosion proof and suppression device for dust pelletizing system, for the explosion arrestment back-fire relief of pipeline, comprise: extinguish and anti-explosion parts, first guide assembly, transmission component and check valve sheet, described extinguish and anti-explosion parts, first guide assembly, transmission component and check valve sheet be successively set on described pipeline away from impact wave line of propagation, described first guide assembly comprises fixed pulley, first guide card and pulley line, described transmission component comprises block and weight, described pulley line connects described first guide card and connects described block via described fixed pulley, described block is arranged on the bottom of described weight for fixing described weight, described check valve sheet abuts the bottom of described weight.
In the utility model preferred embodiment, described first guide card is vertical with impact wave line of propagation.
In the utility model preferred embodiment, described extinguish and anti-explosion parts comprise extinguishing chemical, Explosion suppressant one or more.
The beneficial effects of the utility model are: the explosion proof and suppression device that the utility model is used for dust pelletizing system can stop explosion wave, in without external source situation, utilize explosion wave pressure itself to trigger device of blast prevention, by external source interference, reliable for effect, the explosion proof and suppression device for dust pelletizing system universal on have market prospects widely.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
